TwinssCan — Gene-Environment Interaction in Psychotic and Depressive Intermediate Phenotypes: Risk and Protective Factors in a General Population Twin Sample

Abstract: Meta-analyses suggest that clinical psychopathology is preceded by dimensional behavioral and cognitive phenotypes such as psychotic experiences, executive functioning, working memory and affective dysregulation that are determined by the interplay between genetic and nongenetic factors contributing to the severity of psychopathology. The liability to mental ill health can be psychometrically measured using experimental paradigms that assess neurocognitive processes such as salience attribution, sensitivity to… Show more

“…Parameter estimates to construct the simulated data sets were based on similar data from an adolescent and young adult twin data set described elsewhere (i.e., TwinssCan) ( 48 , 49 ). Access to this data set only allowed us to test the power of the direct associations between parenting styles and mean daily-life social experience, as participants were not asked in the experience sampling whether they were with mothers/fathers specifically—thereby not allowing for the testing of our described interaction effects.…”

“…The current sample was recruited as part of the TwinssCan study, a longitudinal twin study that was developed to investigate gene-environment interactions in the development of psychopathology in adolescent twins and their siblings (Pries et al, 2019). All participants were recruited through the East Flanders Prospective Twin Survey (EFPTS; Derom et al, 2013), a prospective and population based twin registry.…”

“…We aimed to extend previous research by using the ESM to investigate the quantity and quality of social behaviours and experiences in youths' everyday lives and associations with self-reported psychopathology symptoms. Our first study (Study 1) was a post-registered 13 analysis (i.e, a form of pre-registration for pre-existing data) from a large youth twin study 14 . We initially set out to perform these analyses in one sample and our post-registration (for Study 1 only) reflects this.…”

“…For Study 1, N=778 adolescent and adult twins aged 15-35 and their non-twin siblings were recruited as part of the TwinssCan study, which in turn was part of the East Flanders Prospective Twin Survey (see 14 The inclusion criterion for both studies was an adequate understanding of the study procedures, and for Study 1, being a member of a monozygotic or dizygotic twin pair, or a sibling of a twin. Exclusion criteria were being over 21 years of age, and having less than 30% compliance to the ESM protocol, resulting in n=663 for Study 1, and n=1027 for Study 2.…”
