Abstract

Background: Offspring of parents with bipolar disorder have increased risks of their own psychopathology. However, a large‐scale survey of psychiatric, somatic, and adverse social outcomes up to adulthood, which could aid in prioritizing and tailoring prevention, is lacking. It also remains to clarify how risks are modified by other parental factors. Methods: Swedish population registers were linked to compare offspring having (N = 24,788) and not having (N = 247,880) a parent with bipolar disorder with respect to psychiatric diagnoses and psychotropic medication, birth‐related and somatic conditions, social outcomes, accidents, suicide attempts, and mortality. Individuals were followed until age 18. We estimated the influence of lifetime parental psychiatric comorbidity, bipolar disorder subtype, and sex on outcomes. Results: Children of parents with bipolar disorder had 2–3 times higher risks of all psychiatric diagnoses, except for bipolar disorder, for which the risk was 11‐fold. Significantly increased risks were also found for several somatic conditions, low school grades, criminal behavior, victimization, accidents, and suicidal behavior. Adjusting for lifetime parental psychiatric comorbidity attenuated most associations. Offspring of a parent with bipolar disorder type 2 had statistically significantly higher risks of attention deficit hyperactivity disorder, respiratory tract conditions, and accidents compared with offspring of a parent with bipolar disorder type 1. Offspring of mothers with bipolar disorder had higher risks of several psychiatric diagnoses, respiratory tract conditions, low school grades, and accidents compared with offspring of fathers with bipolar disorder. Having two parents with bipolar disorder entailed the highest risks of psychiatric outcomes in offspring. Conclusions: Early intervention and family support are particularly warranted for the offspring of a parent with bipolar disorder in the presence of lifetime parental psychiatric comorbidity, when the parent has bipolar disorder type 2, or when the mother or both parents have bipolar disorder.

9. Visual Disengagement: Genetic Architecture and Relation to Autistic Traits in the General Population

Author

Siqueiros Sanchez, Monica, Pettersson, Erik, Kennedy, Daniel P., Bölte, Sven, Lichtenstein, Paul, D'Onofrio, Brian M., and Falck-Ytter, Terje

Abstract

Visual disengagement has been hypothesized as an endophenotype for autism. In this study we used twin modelling to assess the role of genetics in basic measures of visual disengagement, and tested their putative association to autistic traits in the general population. We used the Gap Overlap task in a sample of 492 twins. Results showed that most of the covariance among eye movement latencies across conditions was shared and primarily genetic. Further, there were unique genetic contributions to the Gap condition, but not to the Overlap condition--i.e. the one theorized to capture visual disengagement. We found no phenotypic association between autistic traits and disengagement, thus not supporting the hypothesis of visual disengagement as an endophenotype for autistic traits.

14. Associations Between General and Specific Mental Health Conditions in Young Adulthood and Cardiometabolic Complications in Middle Adulthood : A 40-Year Longitudinal Familial Coaggregation Study of 672,823 Swedish Individuals

Abstract

OBJECTIVE: Most mental disorders, when examined individually, are associated with an increased risk of cardiometabolic complications. However, these associations might be attributed to a general liability to psychopathology or confounded by unmeasured familial factors. The authors investigated the association between psychiatric conditions in young adulthood and the risk of cardiometabolic complications in middle adulthood, up to 40 years later. METHODS: This cohort study (N=672,823) identified all individuals and their siblings born in Sweden between 1955 and 1962 and followed the cohort through 2013. Logistic regression models were used to estimate the bivariate associations between 10 psychiatric conditions or criminal convictions and five cardiometabolic complications in individuals. A general factor model was used to identify general, internalizing, externalizing, and psychotic factors based on the comorbidity among psychiatric conditions and criminal convictions. The cardiometabolic complications were then regressed on the latent general factor and three uncorrelated specific factors within a structural equation modeling framework in individuals and across sibling pairs. RESULTS: Each psychiatric condition significantly increased the risk of cardiometabolic complications. These associations appeared nonspecific, as multivariate models indicated that most were attributable to the general factor of psychopathology, rather than to specific psychiatric conditions. There were no or only small associations between individuals' general psychopathology and their siblings' cardiometabolic complications. The same pattern was evident for the specific internalizing and psychotic factors. CONCLUSIONS: Associations between mental disorders in early life and later long-term risk of cardiometabolic complications appeared to be attributable to a general liability to psychopathology. Familial coaggregation analyses suggested that the elevated risk could not be attributed to con, Supported by the Swedish Research Council for Health (grant 2017-01358) , ALF Funding from the Stockholm Region (grant 20190712), and the China Scholarship Council.

Abstract

Objective: Associations were examined between six psychiatric diagnoses in parents and a broad range of psychiatric and nonpsychiatric outcomes in their offspring. Methods: All individuals born in Sweden between 1970 and 2000 were linked to their biological parents (N=3,286,293) through Swedish national registers. A matched cohort design, with stratified Cox regression and conditional logistic regression analyses, was used examine associations between six psychiatric diagnoses in the parents and 32 outcomes in their offspring. All children, including those exposed and those not exposed to parents with psychiatric diagnoses, were followed from their date of birth to the date of emigration from Sweden, death, or December 31, 2013, when the offspring were 14–44 years old. Results: In terms of absolute risk, most children who had parents with psychiatric diagnoses were not diagnosed in specialist care themselves, and the proportion of offspring having any of the 16 types of psychiatric conditions ranged from 22.17% (of offspring exposed to parental depression) to 25.05% (of offspring exposed to parental drug-related disorder) at the end of follow-up. Nevertheless, in terms of relative risk, exposure to any of the six parental psychiatric diagnoses increased probabilities of the 32 outcomes among the offspring, with hazard ratios that ranged from 1.03 to 8.46 for time-to-event outcomes and odds ratios that ranged from 1.29 to 3.36 for binary outcomes. Some specificities were observed for parental diagnoses of psychosis and substance-related disorders, which more strongly predicted psychotic-like and externalizing-related outcomes, respectively, in the offspring. Conclusions: The intergenerational transmission of parental psychiatric conditions appeared largely transdiagnostic and extended to nonpsychiatric outcomes in offspring. Given the broad spectrum of associations with the outcomes, service providers (e.g., psychiatrists, teachers, and social workers) should consider clients' broader psychiatric family history when predicting prognosis and planning interventions or treatment.

Abstract

Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts. Extraversion item data from multiple personality inventories were harmonized across inventories and cohorts. No genome-wide significant associations were found at the single nucleotide polymorphism (SNP) level but there was one significant hit at the gene level for a long non-coding RNA site (LOC101928162). Genome-wide complex trait analysis in two large cohorts showed that the additive variance explained by common SNPs was not significantly different from zero, but polygenic risk scores, weighted using linkage information, significantly predicted extraversion scores in an independent cohort. These results show that extraversion is a highly polygenic personality trait, with an architecture possibly different from other complex human traits, including other personality traits. Future studies are required to further determine which genetic variants, by what modes of gene action, constitute the heritable nature of extraversion.

Abstract

ImportanceNeuroticism is a pervasive risk factor for psychiatric conditions. It genetically overlaps with major depressive disorder (MDD) and is therefore an important phenotype for psychiatric genetics.

32. Brief Report: Association between Autism Spectrum Disorder, Gastrointestinal Problems and Perinatal Risk Factors within Sibling Pairs

Author

Isaksson, Johan, Pettersson, Erik, Kostrzewa, Elzbieta, Diaz Heijtz, Rochellys, and Bölte, Sven

Abstract

Autism spectrum disorder (ASD) has been associated with gastrointestinal (GI) problems, but the nature of this association is unclear. Parents to siblings, concordant or discordant for ASD (N = 217), participated in a web survey covering mother's weight gain during pregnancy, maternal viral/bacterial infection and use of antibiotics, duration of breastfeeding, mode of delivery, birth weight and child GI problems. ASD was associated with GI problems and perinatal environmental risk, based on a summation of maternal infection and antibiotic use during pregnancy and/or the breastfeeding period. The association between GI problems and ASD remained within the sibling pairs (ß = 1.23; p < 0.001) in the adjusted model. Our results indicate non-shared environmental effects on the ASD/GI association, but none of the factors examined explained the link.

35. Opportunities of measuring hierarchical models of psychopathology.

*PATHOLOGICAL psychology, *PSYCHOMETRICS, *PSYCHIATRIC diagnosis, *PSYCHOLOGICAL distress, *TEST design
Abstract

All psychiatric phenomena are positively associated, and several different models can account for this observation. These include the correlated factors, network, general psychopathology as outcome, and hierarchical models. Advantages of hierarchical models, which consist of one general and several (general factor‐residualized) specific factors, is that the general factor provides an opportunity to reliably measure global distress and impairment, while the specific factors might improve the ability to discriminate between individuals with different kinds of problems. Nevertheless, other models also have their respective advantages, and it remains challenging to empirically determine which model best accounts for the positive manifold in psychiatry. Instead, I present two non‐empirical arguments in favor of hierarchical models. First, by measuring the general factor in isolation, the specific factors tend to include both favorable and unfavorable correlates, which might reduce stigma compared to psychiatric diagnoses that by and large are associated with only unfavorable outcomes. Second, the general psychopathology factor displays an unusual psychometric property in that it includes symptoms of opposite meaning if they have similar valence (e.g., self‐reported symptoms such as gullible and paranoid, lazy and workaholic, and terrified and apathetic load in the same direction), which one might want to measure in isolation from variance capturing the content of symptoms. I conclude by speculating that tests designed based on hierarchical models might help clinical assessment. [ABSTRACT FROM AUTHOR]

38. Comparative study across multiple industries how hybrid-, onsite, and remote work setting affect collaboration

Author

Pettersson, Erik, Fyrner, Timmy, Pettersson, Erik, and Fyrner, Timmy

Abstract

Background: The outbreak of COVID-19 generated challenges for both employers andemployees over a broad spectrum of industries. People were recommended to observe socialdistancing and lockdowns and/or curfews for non-essential businesses were implemented. Thisglobal situation catalyzed process innovation and a transition from traditional work settings,specifically on-site work, to a remote work setting where employees use online communicationrequiring homes with computers and high-speed internet. Purpose: This thesis explores how work settings changed due to the pandemic, how differentwork settings affect work-related collaborations which is a cornerstone in the innovationprocess, but also to investigate differences amongst personality traits in various work settings. Methodology: The research presented herein is based on a quantitative survey of 156respondents from a multitude of industries including several countries. The survey wasdesigned using the Likert scale to capture how respondents perceived various aspects ofcollaboration before, during, and after the COVID-19 pandemic. In addition to respondent’sperceptions, relevant demographic information was collected. The survey results were analyzedusing descriptive statistics, CFA, SEM analysis, and statistical tests. Results and Analysis: Differences between work settings were found regarding certain aspectsof collaboration. The most notable was that informal collaboration was limited when workingfrom home. The most important aspects of collaboration are to be able to trust collaborativepartners and feel mutual respect. Conclusions: Employers need to develop digital communication tools and collaborationpractices when adopting a hybrid workplace. Informal interactions are an important aspect ofcollaboration, and these interactions are limited when working from home. Management needsto nurture an atmosphere of trust and mutual respect for successful collaboration. Recommendations for future research: Studies are reco

Abstract

IMPORTANCE: Psychiatric conditions in parents are associated with many psychiatric and nonpsychiatric outcomes in offspring. However, it remains unknown whether this intergenerational transmission is attributable to broader psychopathology comorbidity or to specific conditions. OBJECTIVE: To estimate associations between general and specific psychopathology factors in parents and a wide range of register-based outcomes in their offspring. DESIGN, SETTING, AND PARTICIPANTS: This Swedish national register-based cohort study included 2 947 703 individuals born between 1970 and 2000 and followed up with participants through December 31, 2013. Statistical analysis was performed from October 2022 to October 2023. EXPOSURES: Hierarchical factor model consisting of 1 general and 3 specific psychopathology factors fit to 9 parental psychiatric diagnoses and violent criminal court convictions. MAIN OUTCOMES AND MEASURES: A total of 31 outcomes were measured in offspring and sorted into 6 broad clusters: psychotic-like outcomes, neurodevelopmental outcomes, internalizing outcomes, externalizing outcomes, behavior and accidents, and psychosocial outcomes. RESULTS: Of 2 947 703 individuals, 1 518 252 (51.5%) were male, and the mean (SD) age at the end of follow-up was 28.7 (8.9) years. The general psychopathology factor in parents was significantly associated with all 31 offspring outcomes (range: odds ratio [OR] for accidents, 1.08 [95% CI, 1.07-1.08] to OR for social welfare recipiency, 1.40 [95% CI, 1.39-1.40]), which means that children whose parents scored 1 SD above the mean on the general psychopathology factor had an 8% to 40% higher odds of different studied outcomes. The specific psychotic factor in parents was primarily associated with all 5 psychotic-like outcomes (range: OR for prescription of antiepileptics, 1.05 [95% CI, 1.04-1.06] to OR for schizophrenia, 1.25 [95% CI, 1.23-1.28]) and the specific internalizing factor in parents was primarily associated with all, Funding Agency:Chinese Scholarship Council CSC202106380087

Abstract

IMPORTANCE: General and specific factors of psychopathology are associated with future adverse outcomes, indicating that they might be useful for identifying individuals at greatest risk. However, it remains unknown if these associations are attributable to confounders that may influence both the psychopathology factors and later outcomes. OBJECTIVE: To analyze associations between psychopathology factors and clinically relevant outcomes within family pairs, adjusting for unmeasured confounds by applying co-twin control and sibling comparison designs. DESIGN, SETTING, AND PARTICIPANTS: This longitudinal cohort study with a follow-up range of 9 to 13 years included all Swedish twins born from 1959 to 1985 who participated in the Study of Twin Adults: Genes and Environment (60% response rate) and the oldest pair of all Swedish siblings born from 1959 to 1985 per the Multi-Generation Register. Twins were evaluated based on responses to a hierarchical factor model derived using multivariate statistics. Sibling pairs were evaluated based on psychiatric diagnoses per the Swedish National Patient Register. Information on outcome events and prescriptions were derived from the National Patient Register, Prescribed Drug Register, and Crime Register. Baseline assessment was in August 2005, and data were analyzed from January 2022 to February 2023. EXPOSURES: Hierarchical factor model consisting of 1 general and 4 specific factors fit to 48 psychiatric symptoms on which twin participants self-reported in 2005 and 1 general and 3 specific factors fit to 9 register-based psychiatric diagnoses assigned to sibling participants prior to 2005. MAIN OUTCOMES AND MEASURES: Outcomes consisted of 7 register-based events occurring after 2005, including suicidal behavior, substance overdoses, and criminal suspicion or convictions (data available until the end of 2013), and prescription of antidepressants, antialcohol or antiopioid medication, antipsychotics, and stimulants (data available

42. Different Neurodevelopmental Symptoms Have a Common Genetic Etiology

Author

Pettersson, Erik, Anckarsäter, Henrik, Gillberg, Christopher, and Lichtenstein, Paul

Abstract

Background: Although neurodevelopmental disorders are demarcated as discrete entities in the Diagnostic Statistical Manual of mental disorders, empirical evidence indicates that there is a high degree of overlap among them. The first aim of this investigation was to explore if a single general factor could account for the large degree of observed overlap among neurodevelopmental problems, and explore whether this potential factor was primarily genetic or environmental in origin. The second aim was to explore whether there was systematic covariation, either genetic or environmental, over and above that contributed by the potential general factor, unique to each syndrome. Method: Parents of all Swedish 9- and 12-year-old twin pairs born between 1992 and 2002 were targeted for interview regarding problems typical of autism spectrum disorders, ADHD and other neurodevelopmental conditions (response rate: 80 percent). Structural equation modeling was conducted on 6,595 pairs to examine the genetic and environmental structure of 53 neurodevelopmental problems. Results: One general genetic factor accounted for a large proportion of the phenotypic covariation among the 53 symptoms. Three specific genetic subfactors identified "impulsivity," "learning problems," and "tics and autism," respectively. Three unique environment factors identified "autism," "hyperactivity and impulsivity," and "inattention and learning problems," respectively. Conclusion: One general genetic factor was responsible for the wide-spread phenotypic overlap among all neurodevelopmental symptoms, highlighting the importance of addressing broad patient needs rather than specific diagnoses. The unique genetic factors may help guide diagnostic nomenclature, whereas the unique environmental factors may highlight that neurodevelopmental symptoms are responsive to change at the individual level and may provide clues into different mechanisms and treatments. Future research would benefit from assessing the general factor separately from specific factors to better understand observed overlap among neurodevelopmental problems.

Abstract

© 2020, The Author(s), under exclusive licence to Springer Nature Limited.Lithium is a first-line medication for bipolar disorder (BD), but only one in three patients respond optimally to the drug. Since evidence shows a strong clinical and genetic overlap between depression and bipolar disorder, we investigated whether a polygenic susceptibility to major depression is associated with response to lithium treatment in patients with BD. Weighted polygenic scores (PGSs) were computed for major depression (MD) at different GWAS p value thresholds using genetic data obtained from 2586 bipolar patients who received lithium treatment and took part in the Consortium on Lithium Genetics (ConLi+Gen) study. Summary statistics from genome-wide association studies in MD (135,458 cases and 344,901 controls) from the Psychiatric Genomics Consortium (PGC) were used for PGS weighting. Response to lithium treatment was defined by continuous scores and categorical outcome (responders versus non-responders) using measurements on the Alda scale. Associations between PGSs of MD and lithium treatment response were assessed using a linear and binary logistic regression modeling for the continuous and categorical outcomes, respectively. The analysis was performed for the entire cohort, and for European and Asian sub-samples. The PGSs for MD were significantly associated with lithium treatment response in multi-ethnic, European or Asian populations, at various p value thresholds. Bipolar patients with a low polygenic load for MD were more likely to respond well to lithium, compared to those patients with high polygenic load [lowest vs highest PGS quartiles, multi-ethnic sample: OR = 1.54 (95% CI: 1.18–2.01) and European sample: OR = 1.75 (95% CI: 1.30–2.36)]. While our analysis in the Asian sample found equivalent effect size in the same direction: OR = 1.71 (95% CI: 0.61–4.90), this was not statistically significant. Using PGS decile comparison, we found a similar trend of association between a high genetic loading for MD and lower response to lithium. Our findings underscore the genetic contribution to lithium response in BD and support the emerging concept of a lithium-responsive biotype in BD.

Abstract

Background The statistics of mental health problems in the UK portrays a dark picture: 1 in 10 children have a diagnosable mental health disorder, approximately three children in every classroom (Green, McGinnity, Meltzer, Ford, & Goodman, 2009; Murphy & Fonagy, 2012). These mental health problems may have a long shadow later in life for children (Kelly-Irving et al., 2013; Kessler, Foster, Saunders, & Stang, 1995); they also affect children's families (Bogels & Brechman-Toussaint, 2006) as well as the overall economy (Prince et al., 2007). In addition to being associated with adverse life outcomes, these mental health problems can lead to self-harm and suicide (Fombonne, Wostear, Cooper, Harrington, & Rutter, 2001). Furthermore, studies have shown that the earlier these symptoms appear, the worse the outcome tends to be (Otto et al., 2001). It is of vital importance to identify children who are at greatest risk of developing mental health problems as early as possible because earlier intervention or prevention tends to be most effective (Colizzi, Lasalvia, & Ruggeri, 2020). One way to identify children at highest risk of developing mental health problems is to study their vulnerability to any mental health problems rather than focusing on the risk of a specific disease, taking into account both genetic and environmental risk factors. Recent research has provided empirical evidence for a general factor of psychopathology (p-factor), indicating that the range of psychopathology symptoms, from internalizing to externalizing problems, can be summarized by a common latent factor that explains a large part of the variance. This p-factor, capturing the vulnerability to mental health problems, emerges taking into account dimensionality of disorders (quantitative continuum of symptoms) as well as diagnoses, persistence and co-occurrence of the range of disorders (Allegrini et al., 2020; Caspi et al., 2014; Martel et al., 2017), both during childhood and adulthood. The p-factor is predictive of multiple negative outcomes, general wellbeing and impairment throughout life (Caspi & Moffitt, 2018). The p-factor is analogous to the g-factor (general cognitive ability, intelligence) indicating that a common factor characterizes a range of cognitive abilities, although there is some specificity for verbal, non-verbal and spatial abilities (Carroll, 1993). Similarly, there is some specificity for psychopathology symptoms after accounting for the p-factor (Allegrini et al., 2020; Selzam, Coleman, Caspi, Moffitt, & Plomin, 2018). An important factor to consider is what explains the wide individual differences in p-factor. Individual differences in mental health problems are explained by both genetic and environmental factors. Twin and family studies have shown that virtually all dimensions of psychopathology are explained by substantial genetic influence, with heritability estimates ranging from 30-80% (Knopik, Neiderhiser, DeFries, & Plomin, 2017). Behavioural genetic and genomic studies have also indicated substantial genetic correlations across dimensions of psychopathology, as well as across medical diagnoses, implying that shared genetic factors contribute to the co-occurrence of the range of dimensions of psychopathological traits and diagnosed mental health disorders (Allegrini et al., 2020; Knopik et al., 2017). The common p-factor is also found to be highly heritable (50-60%) during childhood and adolescence and highly heritable across raters (Allegrini et al., 2020). Great progress has been made in identifying specific genetic markers associated with a range of mental health problems (Visscher et al., 2017). Individually these markers are not very useful because their effect sizes are very small. However, markers can be aggregated in genome-wide polygenic scores (GPS) to predict psychopathology symptoms across development (Middeldorp & Wray, 2018). The predictive ability of GPS constructed from genome-wide association (GWA) studies of a range of mental health traits has been shown to be significant, but the predictive accuracy is still modest. The goal of the proposed study is to boost the predictive power of GPS by focusing on the p factor. Multivariate prediction models that leverage joint prediction of multiple GWA summary statistics have been shown to be effective in boosting power and predictive accuracy of GPS (Allegrini et al., 2020, 2019; Grotzinger et al., 2019; Maier et al., 2018; Turley et al., 2018). There are several multivariate methods available for researchers to use (Genomic SEM, MTAG, SMTpred). The predictive accuracy for the cognitive traits has been shown to be similar between these different methods (Allegrini et al., 2019). However, to our knowledge it has not been tested empirically for mental health outcomes, that is if the different multivariate methods differ for the prediction for psychopathology symptoms (and diagnoses of mental health problems) across development. The current project will investigate how the genetics of the p-factor can best be captured using methods leveraging GWA summary statistics -- both multi-trait GWA prediction (e.g. Genomic SEM; MTAG) and multi-polygenic score models (e.g. multiple regression; prediction models using the elastic net). We will test whether the way genomic p is constructed leads to differences in prediction in both the dimensional p- factor (continuous measures of psychopathology) and clinical outcomes (diagnoses by a psychiatrist; p-factor) during childhood and early adulthood. We will systematically test the multivariate prediction of GPS (using both multi-GPS and multi-trait GWA prediction) to the p-factor from childhood to emerging adulthood (using data from self-, parent-, teacher-ratings). This project will leverage the most recent GWA summary statistics of psychiatric problems in adulthood. In addition, the project will attempt to boost the power to predict the p factor by including GPS of nonpsychiatric traits, most notably educational attainment and intelligence. It has been shown both phenotypically and genetically that educational attainment and intelligence are predictors of psychiatric problems both during childhood and in adulthood (Harden et al., 2019; Plomin & Deary, 2015). We will test the extent to which polygenic scores derived from GWA summary statistics from intelligence, educational attainment and personality-related phenotypes like neuroticism and risk-taking will increase the prediction of the p-factor. We will test the prediction in both dimensional/quantitative measures of mental health as well as clinical outcomes of mental health using multivariate genomic prediction methods building on work by Mallard and colleagues (2019), which suggests that diagnostic criteria in adulthood are only moderately related to self-reported symptoms (Mallard et al., 2019). Here we will test the prediction of p- factor in self-, parent- and teacher ratings, as well as clinical diagnoses across childhood and adulthood. Finally, we will study the specificity of psychiatric problems after accounting for genomic p factor. There are symptom-specific genomic factors, or residual variance in psychopathology after controlling for multivariate GPS predictions (genomic p-factor) (Grotzinger et al., 2019). Here we will test how this symptom-specific variance could increase prediction of specific symptoms of psychopathology (internalizing, externalizing and neurodevelopmental disorders) during childhood and emerging adulthood, over and above the genomic p factor. Genomic SEM will be employed to fit the common pathway model to the multivariate data using summary statistics of adult psychiatric GWA, testing for both common and specific factors of psychopathology. Using the summary statistics derived from Genomic SEM, we will construct GPS to test the variance explained in the phenotypic p-factor and the specific psychopathology symptoms from childhood to emerging adulthood in two representative samples from the UK and Sweden. Our project will take a systematic look at how the genetics of p can best be aggregated to predict the predisposition to psychopathology from childhood to early adulthood. This prediction could potentially be useful in order to identify children at greatest risk who would benefit most from early prevention and intervention. Additionally, the future potential impact of this work would allow using the genomic p factor in studies as a control variable. When studies explore the environmental risk factors of psychopathology, genetic p allows to partially control for genetic confounding, thus getting a cleaner measure of non-genetic, environmental risk factors of adverse mental health.

49. The nature of psychopathology

Abstract

Readers of JCPP Advances known that the dominant classification system (Diagnostic and Statistical Manual of Mental Disorders) in psychiatry and psychology conceptualizes psychopathology as discrete diagnostic categories. This measurement model builds on a strong assumption of a clear discontinuity between individuals who meet criteria for a diagnosis and those who don't fulfill diagnostic criteria. During the past decades we have seen huge efforts to test this assumption and explore alternative models, such as research from the hierarchical taxonomy of psychopathology consortia. Key findings of these efforts are reviewed and discussed in the December issue of JCPP Advances.

Abstract

Understanding the relationship between chronic pain conditions and suicidal behavior is imperative for suicide prevention efforts. Although chronic pain conditions are associated with suicidal behaviors, these associations might be attributed to unmeasured confounding, or mediated via pain comorbidity. We linked a population-based Swedish twin study (N = 17 148 twins) with 10 years of longitudinal, nationwide records of suicidal behavior from health and mortality registers through 2016. To investigate whether pain comorbidity versus specific pain conditions were more important for later suicidal behavior, we modeled a general factor of pain and two independent specific pain factors (measuring pain-related somatic symptoms and neck-shoulder pain, respectively) based on 9 self-reported chronic pain conditions. To examine whether the pain-suicidal behavior associations were attributable to familial confounding, we applied a co-twin control model. Individuals scoring one standard deviation above the mean on the general pain factor had 51% higher risk of experiencing suicidal behavior (Odds Ratio (OR), 1.51; 95% Confidence Interval (CI), 1.34–1.72). The specific factor of somatic pain was also associated with increased risk for suicidal behavior (OR, 1.80; 95% CI, 1.45–2.22]). However, after adjustment for familial confounding, the associations were greatly attenuated and not statistically significant within monozygotic twin pairs (general pain factor OR, 0.89; 95% CI, 0.59–1.33; somatic pain factor OR, 1.02; 95% CI, 0.49–2.11) Clinicians might benefit from measuring not only specific types of pain, but also pain comorbidity; however, treating pain might not necessarily reduce future suicidal behavior, as the associations appeared attributable to familial confounding., Funding agencies:American Foundation for Suicide Prevention SRG-0-133-19China Scholarship Council CSC201806360008
