Eivind Ystrom is professor of personality psychology and leader of the genetics research group at PROMENTA Research Center (GeoGen). His main research interest is gene-environment interplay for early life socioeconomic status and mental health development. This includes extended pedigree and molecular genetic studies on genetic transmission; how heritable traits in parents have effect on children, or “genetic nurture”; and how genetic effects varies over schools and neighbourhoods.

He is currently leading the ERC Consolidator project “The PsychoGeography of Intergenerational Mobility” and the Research Council of Norway FRIPRO project “Early Life SocioEconomic status, mental health, and educational performance: an evaluation of sensitivity to the environment (ELiSE)”. He is a partner in the ERC MSCA Doctoral Network “the European Social Science Genetics Network (ESSGN)” and the Nordforsk collaborative project “Post-Pandemic Vulnerability and Resilience (SISU)”.

The GeoGen team integrates national registries and large genotyped cohort studies to apply designs for separating direct and indirect genetic effects and uncover how heritable traits interacts with the environments in shaping children’s psychological development.

He is associate editor of JCPP Advances.

Prenatal and postnatal depression potentially have severe consequences, but we do not know to what extent they have the same etiological factors. Genetically informative designs yield insight into common etiology between pre- and postnatal depression and inform on potential prevention and intervention efforts. This study evaluates the overlap in genetic and environmental factors in pre- and postnatal depression symptoms. Methods We conducted univariate and bivariate modeling, using a quantitative, extended twin study. The sample was a subsample of the MoBa prospective pregnancy cohort study in 6039 pairs of related women. Measurement was conducted at week 30 of pregnancy and 6 months following delivery, using a self-report scale. Results The heritability of depressive symptoms was 16.2 % (95 % CI = 10.7–22.1) prenatally and 25.7 % (95 % CI = 19.2–32.2) postnatally. The correlation between risk factors for prenatal and postnatal depressive symptoms was at unity ( r = 1.00) for genetic effects, and at disunity ( r = 0.36) for environmental effects. The genetic effects for postnatal depressive symptoms were 1.7 times larger compared to prenatal depressive symptoms. Limitations Although genes for depression become more influential postpartum, only future studies can inform on the mechanisms for such a socio-biological augmentation of effect. Conclusion Genetic risk factors for prenatal and postnatal depressive symptoms are indistinguishable in kind, with greater impact after birth, whereas environmental risk factors for depression symptoms are mostly non-overlapping before and after birth. These findings indicate that interventions could be of different kind before and after birth.

Background We examine whether associations between prenatal exposure to hazardous maternal alcohol consumption during the first trimester of pregnancy and sleep problems in young children represent a causal association. Methods The population-based sample consists of 15,911 mothers with 30,395 offspring from the Norwegian Mother, Father, and Child Cohort Study (MoBa) and the Medical Birth Registry of Norway (MBRN). Women self-reported pre-pregnancy alcohol consumption and consumption during the first trimester of pregnancy twice: at gestational weeks 17 and 30. Mothers reported their children's sleep problems, when they were 1.5 and 3 years (mean = 50; SD = 10). We tested models adjusting for (1) measured confounders, (2) unmeasured familial risk factors by sibling design, and (3) maternal hazardous drinking in the 3 months prior to pregnancy as an instrumental variable within the sibling design. Results Children of mothers with hazardous drinking during the first trimester were at increased risk of sleep problems at 1.5 (β = 1.14, 95%CI 0.04–2.25) and 3 (β = 2.86, 95%CI 1.85–3.87) years of age. These associations were reduced to close to zero and non-significant at 1.5 (β = −0.32, 95%CI −1.91–1.26) and 3 (β = 0.06, 95%CI −1.56–1.64) years when controlling for both familial and measured environmental risk factors. Conclusions There is a moderate association between maternal hazardous drinking during pregnancy and offspring sleep problems up to age three. This association is explained by risk factors differing between families and does not reflect a cause-effect relationship.

Aims: Certain risk constellations of parental drinking, mental health and years of education are prospectively associated with offspring’s risk for a diagnosis of anxiety/depression, but it remains unknown how they may relate to other aspects of offspring’s mental health. We examined whether such risk constellations were also prospectively associated with the extent of offspring’s utilisation of healthcare services for anxiety/depression. Methods: The sample included 8773 adolescent offspring of 6696 two-parent families who participated in the Nord-Trøndelag Health Study in Norway. The exposures consisted of five parental risk constellations characterised by drinking frequencies and quantities, years of education and mental health previously derived based on the parental self-reports using latent profile analysis. The outcomes were the number of years in contact, and the total number of consultations/visits, with healthcare services for anxiety/depression in adolescents and young adults as recorded in healthcare registries in the period 2008–2014. Associations were examined using zero-inflated negative binomial regression models, accounting for demographics and offspring’s early mental health. Results: Parental risk constellations were not significantly associated with the extent of offspring’s healthcare utilisation for anxiety/depression during the seven-year study period, neither in respect of number of years nor in number of contacts. Conclusions: Offspring of four risky constellations were no more likely to use healthcare services for longer time periods or have more consultations/visits than offspring of the lowest-risk constellation. Parental risk constellations appear more informative for understanding disorder aetiology than for understanding management and treatment of anxiety and depression during adolescence and early adulthood.

Objective: Fatigue is a common symptom in somatic and mental illness. Musculoskeletal pain and psychological distress have in turn frequently been shown to be associated with fatigue across clinical conditions and in the general population. The study aims to disentangle direct effects from those due to mere confounding from shared etiologies. Design: The study used genetically informative longitudinal twin data, through a co-twin control design with an additional within-person dimension. Methods: Data on fatigue, pain and distress from 2196 mono – and dizygotic twins from the Norwegian Twin Registry examined at two time points five years apart was analyzed using multilevel generalized linear regression modeling. Fatigue was regressed on pain and distress, with further controls added for confounding from genetic and stable non-shared environmental sources. Results: Pain and distress had a significant impact on fatigue at genetic, stable non-shared environmental and time-varying levels, even when controlling for somatic comorbidity. Conclusion: The findings indicate that a significant proportion of the association between fatigue, pain and distress is due to genetic and environmental confounding. Pain and distress exert significant, albeit smaller effects on fatigue even when controlling for genetic and stable environmental contributions, indicating direct effects. Potential etiological pathways and underlying mechanisms are discussed.

Educational attainment and mortality in schizophrenia. Acta Psychiatrica Scandinavica. ISSN 0001-690X. 145(5), s. 481–493. doi: 10.1111/acps.13407. Fulltekst i vitenarkiv Vis sammendrag
Background Individuals suffering from schizophrenia have a reduced life expectancy with cardiovascular disease (CVD) as a major contributor. Low educational attainment is associated with schizophrenia, as well as with all-cause and CVD mortality. However, it is unknown to what extent low educational attainment can explain the increased mortality in individuals with schizophrenia. Aim Here, we quantify associations between educational attainment and all-cause and CVD mortality in individuals with schizophrenia, and compare them with the corresponding associations in the general population. Method All Norwegian citizens born between January 1, 1925, and December 31, 1959, were followed up from January 1, 1990, to December 31, 2014. The total sample included 1,852,113 individuals, of which 6548 were registered with schizophrenia. We estimated hazard ratios (HR) for all-cause and CVD mortality with Cox models, in addition to life years lost. Educational attainment for index persons and their parents were included in the models. Results In the general population individuals with low educational attainment had higher risk of all-cause (HR: 1.48 [95% CI: 1.47–1.49]) and CVD (HR: 1.59 [95% CI: 1.57–1.61]) mortality. In individuals with schizophrenia these estimates were substantially lower (all-cause: HR: 1.13 [95% CI: 1.05–1.21] and CVD: HR: 1.12 [95% CI: 0.98–1.27]). Low educational attainment accounted for 3.28 (3.21–3.35) life years lost in males and 2.48 (2.42–2.55) years in females in the general population, but was not significantly associated with life years lost in individuals with schizophrenia. Results were similar for parental educational attainment. Conclusions Our results indicate that while individuals with schizophrenia in general have lower educational attainment and higher mortality rates compared with the general population, the association between educational attainment and mortality is smaller in schizophrenia subjects than in the general population.

Norwegian health survey data (1987 – 2003) were analysed to determine if binge drinking increases the risk of incident major events from ischemic heart disease (IHD) and stroke. Among current drinkers reporting average alcohol intakes between 2 to 60 g/day (n = 44,476), frequent binge drinking (5+ units ≥ once per month) was not associated with a greater risk of IHD (adjusted hazard ratio = 0.91, 95% confidence interval: 0.76, 1.09) nor stroke (adjusted hazard ratio = 0.98, 95% confidence interval: 0.81, 1.19), in comparison with participants who reported that they never or only infrequently (<once per month) had episodes of binge drinking. Participants with an average alcohol intake between 2 – 60 g/day had a lower risk of IHD in comparison with participants with very low intakes (<2 g/day) both among frequent binge drinkers (adjusted hazard ratio = 0.67, 95% confidence interval: 0.56, 0.80) and among never/infrequent binge drinkers (adjusted hazard ratio = 0.75, 95% confidence interval: 0.67, 0.84). The findings suggest that frequent binge drinking does not, independently of the average alcohol intake, increase the risk of incident IHD or stroke events. However, the findings should be interpreted in light of the limitations of the study design.

Abstract Objective: We examined the risk of developing a future alcohol use disorder (AUD) among offspring of families with different constellations of parental risk factors. Method: We analyzed a sample of 8,774 offspring (50.2% male) from 6,696 two-parent families who participated in the Nord-Trøndelag Health Study in Norway when offspring were 13–19 years old in 1995–1997 or 2006–2008. Based on population registry information and parental Nord-Trøndelag Health Study self-reports, families were classified via Latent Profile Analysis into fiver risk constellations reflecting parents’ education, drinking quantities and frequencies, and mental health. Information about AUD-related diagnoses, treatments, and prescriptions for all offspring in the period between 2008 and 2016 was obtained from 3 national health registries and pooled to reflect any AUD. The likelihood of AUD in offspring was examined with a set of nested logistic regression models. Results: Registry records yielded 186 AUD cases (2.1%). Compared with the lowest-risk constellation, offspring from two constellations were more likely to present with AUD in unadjusted analyses. After adjusting for all covariates, including offspring’s alcohol consumption and witnessing parental intoxication during adolescence, AUD risk remained elevated and statistically significant (adjusted odds ratio = 2.34, 95% confidence interval = 1.14, 4.85) for offspring from the constellation characterized by at least weekly binge drinking, low education, and poor mental health in both parents. Conclusion: Weekly binge drinking by both parents was associated with future AUD risk among community offspring in Norway when clustered with additional parental risks such as poor mental health and low educational attainment.

Aims: Mothers with substance use disorders (SUD) often show impairments in parental reflective functioning (PRF), which may have adverse effects on their capacity for sensitive caregiving. Parenting personality is also associated with caregiving. However, no studies have investigated how these individual factors may contribute to variance in PRF in mothers with SUD. In this study PRF and personality were assessed in 43 mothers with SUD. Methods: PRF was assessed by the Parent Development Interview. Personality traits were assessed by the Revised Neuroticism-Extraversion-Openness Personality Inventory. Results: The results indicate that higher levels of the Openness trait are associated with better PRF. Conclusion Mothers low in Openness may need more specific and situational training in interpreting mental states in their children. Highly open mothers with SUD will likely need more help distinguishing the child’s mental states from their own, and might need help to maintain mutuality and regulating the intensity of their responses to the child’s behavior.

Background Different methods in pharmacoepidemiology can be used to study hypnotic use in children. But neither questionnaire-based data nor prescription records can be considered a “gold standard”. This study aimed to investigate the agreement between mother-reported questionnaire-based data and prescription record data for hypnotic drugs in children aged 0–18 months. The agreement was compared to the agreement for a group of antiepileptic drugs. Methods Prescription record data were collected from the Norwegian prescription database for 47,413 children also surveyed in the Norwegian mother and child cohort between 2005 and 2009. Agreement between in the two data sources was calculated using Cohens Kappa. Multinomial logistic regression was used to calculate the effect of sociodemographic variables on discrepancies in data sources. Results The agreement between mother-reported and dispensed hypnotics was less than 50% for all hypnotics. Sensitivity of reporting increased with number of filled prescriptions. The agreement of antiepileptic drugs was 92.9% in the same population. Of several sociodemographic factors only paternal educational level and maternal work situation was significantly related to agreement between prescription record and survey data. Conclusion There was a moderate agreement between reported use and dispensed hypnotic drugs for infants and toddlers. Results indicate that sociodemographic factors play only a minor role in explaining discrepancy.

Background: Epidemiological studies have shown that long-term exposure to paracetamol during pregnancy is associated with attention-deficit/hyperactivity disorder (ADHD). The mechanism by which paracetamol may modulate the increased risk of developing ADHD is currently unknown. We have conducted an epigenome-wide association study (n = 384 cord blood samples) and investigated whether prenatal exposure to paracetamol is associated with DNA methylation in children diagnosed with ADHD. Results: Analyses identified significant differences in DNA methylation (n = 6211 CpGs) associated with prenatal exposure to paracetamol for more than 20 days in children diagnosed with ADHD compared to controls. In addition, these samples were differentially methylated compared to samples with ADHD exposed to paracetamol for less than 20 days (n = 2089 CpGs) and not exposed to paracetamol (n = 193 CpGs). Interestingly, several of the top genes ranked according to significance and effect size have been linked to ADHD, neural development, and neurotransmission. Gene ontology analysis revealed enrichment of pathways involved in oxidative stress, neurological processes, and the olfactory sensory system, which have previously been implicated in the etiology of ADHD. Conclusions: These initial findings suggest that in individuals susceptible to ADHD, prenatal long-term exposure to paracetamol is associated with DNA methylation differences compared to Controls.

Objectives: To evaluate the contribution of genetic and environmental factors for stability in, comorbidity with, and life events related to personality disorders. Methods: DSM-IV criteria for 10 personality disorders were assessed using structured interviews in 2801 Norwegian twins in early adulthood (age 28; range 19-36) and again in 2282 twins 10 years later. Biometric models were used on criteria counts to analyze the genetic and environmental factors for PDs and: 10-year stability, comorbidity with common mental disorders and psychotic-like experiences, substance abuse, and stressful life events. Results: Heritability of PDs were estimated to be 40% to 20% heritable. The 10-year stability estimated as tetrachoric correlation of PDs ranged from .35 to .58. Genetic variants influencing PDs were estimated to be the same over 10 years, the environmental factors were estimated to change 74-84% over the same period. Genetic and environmental factors for comorbidity between PDs and common mental disorders have different dimensionality and structure. The link between PDs and substance use are dependent on the specific criteria endorsed rather than at the disorder level. Stressful life events are important for the development of PDs and substance use over and beyond what can be explained by life-course selection due to genetic risk. Conclusion: Although PDs at specific assessments are mostly influenced by environmental factors, genetic factors are more important in explaining stability and comorbidity. The unequal structure of genetic and environmental factors leads to a mismatch between the observed comorbidity between PDs and mental disorders and the expected commonality in genetic factors. Aggregation of symptoms and disorders according to the estimated genetic structure could improve the precision of molecular genetic studies. This longitudinal twin study has also shown that PDs are related to stressful life events, mental disorders, and substance abuse over and beyond what can be explained by genetic risk.

Factors such as early trauma or abuse are well-established environmental risk factors for the development of Borderline Personality Disorder (BPD). Compared to other mental disorders, little attention has been paid to the contribution of genetic risk factors. The present symposium aims to give an overview of how family and twin studies, and molecular genetic studies can contribute to the understanding of the disorder, and its relationship to risk factors and comorbid disorders: Eivind Ystrom will present on how twin studies can be used to investigate genetic and environmental risk factors contributing to comorbidity between BPD, mental disorders, and substance abuse. Using interview data from a population-based twin study, Ystrom and colleagues have found that genetic factors are the main contributors to the 10-year stability of BPD. Genetic factors for BPD are to a great extent overlapping with the risk for antisocial PD and substance use disorders. However, BPD is related to stressful life events, internalizing symptoms and personality disorders, and substance abuse over and beyond what can be explained by common genetic risk factors. Ralf Kuja-Halkola will present how national health register data can be used to investigate genetic contributions. Using twins and siblings, familial aggregation of clinical BPD diagnosis was investigated, and the heritability of BPD was estimated to 46%. The familial co-aggregation between BPD and attention deficit hyperactivity disorder (ADHD) was estimated, e.g. full siblings of individuals with ADHD diagnosis have a 2.8 times increased risk of having a BPD diagnosis compared to full siblings of individuals without ADHD diagnosis. Additionally, the co-aggregation in full siblings between BPD and a range of psychiatric and somatic disorders, and behavioral traits will be presented. Fabian Streit will present the initial results of the largest genome-wide association study (GWAS) which systematically investigates the contribution of common genetic variants to BPD. In a meta-analysis including over 6000 cases, and 500,000 controls. The results highlight first associated genes, also related to comorbid disorders, such as post-traumatic stress disorder (PTSD), or ADHD. Polygenic risk scores predicted up to 3% of the variance in case-control status. Positive genetic correlations were observed with other psychiatric disorders, most pronounced with PTSD, depression, ADHD, and anxiety. Additional analyses indicated genetic correlations with factors such as somatic disorders, pain, mood swings, childhood maltreatment, and material deprivation. Guy Hindley will present molecular genetic investigations of mood instability, a key component of BPD. A recent GWAS identified a strong positive genetic correlation of the trait with depression but weak correlations with bipolar disorder and schizophrenia. However, genetic correlation does not capture shared genetic variants with mixed effect directions. By applying statistical tools which capture mixed effect directions, the extensive genetic overlap between mood instability and all three mental disorders could be demonstrated, irrespective of their genetic correlation. This overlap was used to identify 246 novel genetic loci associated with mood instability. Biological characterization highlighted a convergence on synaptic gene-sets. These findings indicate shared neurobiological mechanisms between mood instability and diverse mental disorders.

Background: An emerging body of evidence suggests that genetic risk for psychiatric conditions is diffuse, probabilistic in nature, and overlaps substantially across different domains. However, psychiatric conditions are diagnosed and treated as specific disorders based on differentiated symptom clusters. In the context of generalised genetic risk, it remains to be determined how distinct psychiatric conditions emerge. The prospects of using genomic data to predict individual-level risk for psychiatric conditions are at present unclear. For prediction to be useful, it needs to be both sensitive (identifying who is at risk) and specific (at risk for what). While increasing sample sizes for genetic discovery may boost sensitivity, the generalised nature of genetic risk implies that identifying predictors of differentiation of psychiatric symptoms may be needed to increase specificity. The Norwegian Mother, Father, and Child Cohort Study (MoBa) is a large population-based pregnancy cohort with genotype and phenotype data, ideally suited to address these questions. Methods: We used the Child Behavior Checklist to assess behavioural and emotional difficulties at ages 1.5, 3, and 5. Symptom¬ differentiation was operationalised as the relative level of these domains over time (behavioural difficulties – emotional difficulties = differentiation). This means that individuals with high scores have relatively more behavioural than emotional difficulties, and the inverse for low scores. These scores can be compared to overall difficulties (behavioural + emotional = total). Following a preregistered analysis plan, we estimated latent growth trajectories of differentiation across early childhood, as well as mediation effects of differentiation on symptoms of psychiatric conditions at age 8. We tested associations between 10 polygenic scores (PGS) for core neurodevelopmental and psychiatric conditions and the extent (intercept) and rate (slope) of the differentiation process. The analytic sample comprised 57,387 genotyped children (including 12,347 pairs of full siblings) from MoBa. We used multilevel structural equation models to account for unmeasured familial confounding, and corrected for multiple comparisons using FDR. Results: ADHD PGS predicted the extent and rate of differentiation toward behavioural difficulties in early childhood (βintercept = 0.10 [0.09, 0.11]; βslope = 0.02 [0.02, 0.03]), and the extent of differentiation at age 5 in turn mediated 33-37% of the PGS associations with ADHD symptoms at age 8. The ADHD PGS association was smaller for total difficulties (βintercept = 0.05 [0.04, 0.06]; βslope = 0.01 [0.01, 0.02]). Schizophrenia PGS predicted differentiation toward emotional difficulties at age 5 (βintercept = -0.03 [-0.04, -0.02]; βslope = -0.01 [-0.02, -0.01]), and bipolar disorder PGS predicted differentiation toward behavioural difficulties (βintercept = 0.02 [0.01, 0.03]; βslope = 0.01 [0.01, 0.02]) – though in both cases effect sizes were substantially smaller. Discussion: We identify genomic predictors of symptom differentiation in early life. Results support a direct effect of ADHD PGS on differentiation toward behavioural difficulties, independent of individuals’ total burden of symptoms. PGS for schizophrenia and bipolar disorder differentially associates with the development of emotional and behavioural difficulties in early childhood. This research may help refine risk predictions in child psychiatry, an important step to enable early prevention.

Background and aims: Substantial correlations between normal and abnormal personality traits have been found, but there is still little knowledge regarding the extent to which the underlying genetic and environmental influences are shared. Methods: 2,282 Norwegian twins were assessed for DSM-IV criteria for personality disorders using structured interviews. Ten years later years the twins were re-interviewed, and normal personality was assessed using the Big Five Inventory. Multivariate twin models were fitted to the five domains of normal personality and dimensional measures of each of the personality disorders individually. Results: While the heritability of the number endorsed criteria for the personality disorders ranged from 0.2 to 0.41, the proportion of genetic variance that was unique to each PD ranged from 19% for Avoidant to 79% for Schizotypal, with a median of 58% across all PDs. Conversely, the proportion of environmental variance unique to the personality disorder criteria ranged from 79% to 99%, with median of 97%. Conclusion: Our results suggest that a considerable proportion of the genetic variance and virtually all environmental variance is unique to the personality disorders, and not shared with the five broad domains of normal personality.

Backgroundand Aims: The stability over time for avoidant personality disorder (AVPD) and obsessive-compulsive personality disorder (OCPD) has previously been found to be moderate. However, the mechanisms underlying this temporal development are not well understood. In the present study we estimate the influence of genetic and environmental factors on stability and change in AVPD and OCPD. Methods: AVPD and OCPD traits were assessed using the Structured Interview for DSM-IV Personality in 2,793 young adult twins from the Norwegian Institute of Public Health Twin Panel (wave 1). On average 10 years later (wave 2) 2,282 of these were re-interviewed. Longitudinal biometric models were fitted to dimensional representations of AVPD and OCPD. Results: The number of endorsed sub-threshold criteria for both PDs decreased 31% from wave 1 to wave 2. The correlations between the numbers of traits endorsed at the two time points were 0.54 for AVPD and 0.37 for OCPD. Genetic factors contributed 67% and 53%, respectively, to the stability of AVPD and OCPD. The correlations between the genetic factors influencing AVPD and OCPD at the two time points were 1.00 and 0.72 respectively, while the environmental influences correlated 0.26 and 0.23, respectively. The correlation between the stable risk factors for AVPD and OCPD was 0.39 of which 63% was attributable to genetic influences. Conclusion: Both AVPD and OCPD were moderately stable from young to middle adulthood. Stability was in large part due to genetic factors, whereas environmental influences contributed to change.

Borderline and antisocial personality disorder traits in early to middle adulthood: A longitudinal twin study. Vis sammendrag
Background and Aims: Antisocial personality disorder (ASPD) and borderline personality disorder (BPD) share genetic and environmental risk factors. Little is known about the temporal stability of these etiological factors in adulthood. Methods: DSM-IV criteria for ASPD and BPD were assessed using structured interviews in 2,282 Norwegian twins in early adulthood and approximately 10 years later. Longitudinal biometric models were used to analyze the number of endorsed criteria. Results: The mean criterion count for ASPD and BPD decreased 40% and 28% respectively from early to middle adulthood. Rank-order stability was 0.58 for ASPD and 0.45 for BPD. The best-fitting longitudinal twin model included only genetic and individual-specific environmental factors. Genetic effects, both those shared by ASPD and BPD, and those specific to each disorder remained completely stable. The unique environmental effects, however, changed substantially, with a correlation across time of 0.19 for the shared effects, and 0.39 and 0.15 respectively for those specific to ASPD and BPD. Genetic effects accounted for 71% and 72% of the stability over time for ASPD and BPD respectively. The genetic and environmental correlations between ASPD and BPD were 0.73, and 0.43 respectively at both time points. Conclusion: ASPD and BPD traits were moderately stable from early to middle adulthood, mostly due to genetic risk factors which did not change over the10 year assessment period. Environmental risk factors were mostly transient, and appear to be the main source of phenotypic change. Genetic liability factors were, to a large extent, shared by ASPD and BPD.

Objective: To measure the impact of the personality traits of Negative Affectivity and General Self-Efficacy measured during pregnancy to predict breastfeeding status at 4-months postpartum, adjusting for cesarean section, premature birth, parity, maternal age, and years of maternal education. Design: Prospective cohort study. Setting: The data collection was conducted as part of the Norwegian Mother and Child Cohort Study at the Norwegian Institute of Public Health. The national sample of 29,581 mothers completed assessment of Negative Affectivity and General Self-Efficacy at gestation weeks 17 and 30 and completed a self-report questionnaire at 6-months postpartum capturing detailed information about nutrition from birth thru 6 months. Outcome Measures: Mothers were classified with a cut-off at 4 months in the groups full breastfeeding, mixed breastfeeding, and bottle feeding. Results: We found that each interval of high Negative Affectivity increased the odds ratio of mixed breastfeeding (OR, 1.39; 95% CI, 1.27-1.51) and bottle feeding (OR, 1.56; 95% CI, 1.39-1.76), compared to full breastfeeding. Each interval of high General Self-Efficacy decreased the odds ratio of bottle feeding at 4 months (OR, 0.89; 95% CI, 0.83-0.96) but not of mixed breastfeeding (OR, 1.00; 95% CI, 0.95-1.04), compared to full breastfeeding. Conclusions: Our results support the hypothesis that Negative Affectivity and General Self-Efficacy are important antenatal predictors of breastfeeding 4 months postpartum. Adequately addressing the concerns and difficulties of mothers high in Negative Affectivity and low in General Self-Efficacy during prenatal and antenatal care could help prevent difficulties to sustain full breastfeeding.

Svekkelse av kognitive funksjoner som hukommelse og språkforståelse er en utbredt følge av traumatisk hjerneskade. De senere årene har flere studier undersøkt feilfri læring ("errorless learning") som metode for kognitiv rehabilitering etter traumatisk hjerneskade. Studiene rapporterer at feilfri læring gir bedre læringsresultater enn læring gjennom prøving og feiling ("errorful learning"). Feilfri læring baseres på et prinsipp for læring der anledningen til å gjøre feil reduseres eller elimineres. Den aktuelle pasientgruppen regnes som spesielt sårbar for at de feil som gjøres i en læringssituasjon, kan forstyrre innlæringen av riktig informasjon. Så langt har forskning på dette feltet vært konsentrert om kontrollerte, eksperimentelle situasjoner, og har i liten grad dokument klinisk anvendelse av feilfri læring som metode for rehabilitering. Målsetningene for denne studien er 1) å undersøke mulige forbedringer eller raffineringer av læringsteknikker basert på feilfri læring, og 2) evaluere feilfri læring i klinisk rehabilitering av personer som har vært utsatt for traumatisk hjerneskade.

Bakgrunn: Angst og depresjon hos mødre påvirker flere prosesser hos barn som er viktig for utvikling av prososial atferd. Det finnes ikke undersøkelser som har sett på sammenhengen mellom prososial atferd hos barn i førskolealder og mødre med angst og depresjon. Mål: Å undersøke i en ikke-klinisk populasjon om det var en sammenheng mellom prososial atferd hos 3 år gamle barn og mødrenes angst og depresjon når barnet var 6, 18 og 36 måneder. Det andre målet var å undersøke om effekten av mors angst og depresjon ble moderert av om barnet vokste opp sammen med andre barn i husholdningen og om barnet var i barnehage eller lignende på dagtid. Det siste målet var å undersøke om det var en sammenheng mellom varigheten på angsten og depresjonen hos mødrene og barnas prososiale atferd. Metode: Datainnsamlingen ble utført som en del av Den norske mor og barn undersøkelsen(MoBa) ved Nasjonalt folkehelseinstitutt. Utvalget besto av 5314 mødre og barn. Mødrene besvarte spørreskjemaer når de var i 18. svangerskapsuke og da barna var 6, 18 og 36 måneder gamle. Mødrene rapporterte om barnas prososiale atferd, da barna var 3 år gamle. Dette ble målt med prososial skala i SDQ. Mødrene rapporterte om egen angst og depresjon som målt med SCL-8 da barna var 6, 18 og 36 måneder gamle. Prososial atferd ble inndelt i normalskårer (80. prosentil) og lav skårer (20. prosentil). Resultater: Lav prososial atferd hos 3 år gamle barn ble predikert av angst og depresjon hos mor da barnet var 6, 18 og 36 måneder, også etter at det var kontrollert for sosiodemografiske variabler og faktorer i barnets proksimale miljø. Både det å være hjemme med mor eller far i 18. levemåned og hjemme med mor i tredje leveår, predikerte større sannsynlighet for å ha lav prososial atferd, sammenlignet med om barnet var i barnehage eller lignende. Effekten av mors angst og depresjon på barnets prososialitet ble ikke moderert av om barnet var i barnehage eller lignende. Barnas lave prososiale atferd ble predikert av tilbakevendende angst og depresjon hos mor i barnas tre første leveår, men ikke av vedvarende eller kortvarig angst og depresjon. Konklusjon: Angst og depresjon hos mødre har en betydning for 3 år gamle barns utvikling av prososial atferd. Mors angst og depresjon påvirker barnets utvikling av prososial atferd fra det er spedbarn og til det er 3 år gammelt. Selv ikke å tilbringe tid i barnehage, park, hosdagmamma, praktikant eller med far, reduserer denne risikoen.

Denne studiens hovedmål var å undersøke hvilken rolle personlighetstrekk etter femfaktormodellen, og manipuleringstaktikker (Buss, 1992), spilte for tilfredsheten i et parforhold. Det ble postulert at manipuleringstaktikker medierer sammenhengen mellom partners personlighet og egen tilfredshet. Dette ble gjort ved å undersøke følgende sammenhenger: a) forholdet mellom tilfredshet og personlighet, b) forholdet mellom manipuleringstaktikker og personlighet, c) forholdet mellom manipuleringstaktikker og tilfredshet, d) forholdet mellom personlighetstrekk og tilfredshet, mediert av manipuleringstaktikker. Studien har også undersøkt kjønnsforskjeller og personlighetslikhet mellom ektefeller. Denne studien har vært et selvstendig forskningsprosjekt, hvor det har blitt oversatt og satt sammen et spørreskjema bestående av selvrapportert personlighet (BFI), tilfredshet i parforhold (RAS), samt selvrapportert og partnerrapportert bruk av manipuleringstaktikker (ToM) i parforhold. Det ble samlet inn data fra 242 par med barn i grunnskolen, hvor hver av ektefellene svarte selvstendig på hvert sitt skjema. Dataanalysene inkluderte regresjonsanalyse og strukturlikningsmodellering. Resultatene viste at nevrotisisme hadde en negativ sammenheng med tilfredshet, mens omgjengelighet og samvittighetsfullhet hadde en positiv sammenheng med tilfredshet. Videre at egne personlighetstrekk, heller enn ektefellens personlighetstrekk alene var av størst betydning for egen tilfredshet. Det var mange sammenhenger mellom personlighetsrekk og manipuleringstaktikker for både kvinner og menn. De fleste fantes mellom omgjengelighet, nevrotisisme og samvittighetsfullhet i forhold til egenrapporterte manipuleringstaktikker. Bruken av taktikker generelt og umodenhetstaktikker spesielt viste negativ sammenheng med tilfredshet for både kvinner og menn. En strukturell likningsmodell på tilfredshet og personlighet mediert av taktikker viste at egen tilfredshet var predikert av egne personlighetstrekk, og ikke predikert av ektefellens personlighetstrekk alene, men mediert av partners manipuleringstaktikker. Resultatene tyder på at egen personlighet har mer å si for egen tilfredshet enn ektefelles personlighet. Det ser ut til at nevrotisisme og mangel på omgjengelighet og samvittighetsfullhet, sammen med umodenhetstaktikker gir et solid amalgam som forringer ektefellens tilfredshet.
