Systematically Defined Informative Priors in Bayesian Estimation:An Empirical Application on the Transmission of Internalizing Symptoms Through Mother-Adolescent Interaction Behavior
Background Bayesian estimation with informative priors permits updating previous findings with new data, thus generating cumulative knowledge. To reduce subjectivity in the process, the present study emphasizes how to systematically weigh and specify informative priors and highlights the use of different aggregation methods using an empirical example that examined whether observed mother-adolescent positive and negative interaction behavior mediate the associations between maternal and adolescent internalizing symptoms across early to mid-adolescence in a 3-year longitudinal multi-method design. Methods The sample consisted of 102 mother-adolescent dyads (39.2% girls, M-age T1 = 13.0). Mothers and adolescents reported on their internalizing symptoms and their interaction behaviors were observed during a conflict task. We systematically searched for previous studies and used an expert-informed weighting system to account for their relevance. Subsequently, we aggregated the (power) priors using three methods: linear pooling, logarithmic pooling, and fitting a normal distribution to the linear pool by means of maximum likelihood estimation. We compared the impact of the three differently specified informative priors and default priors on the prior predictive distribution, shrinkage, and the posterior estimates. Results The prior predictive distributions for the three informative priors were quite similar and centered around the observed data mean. The shrinkage results showed that the logarithmic pooled priors were least affected by the data. Most posterior estimates were similar across the different priors. Some previous studies contained extremely specific information, resulting in bimodal posterior distributions for the analyses with linear pooled prior distributions. The posteriors following the fitted normal priors and default priors were very similar. Overall, we found that maternal, but not adolescent, internalizing symptoms predicted subsequent mother-adolescent interaction behavior, whereas negative interaction behavior seemed to predict subsequent internalizing symptoms. Evidence regarding mediation effects remained limited. Conclusion A systematic search for previous information and an expert-built weighting system contribute to a clear specification of power priors. How information from multiple previous studies should be included in the prior depends on theoretical considerations (e.g., the prior is an updated Bayesian distribution), and may also be affected by pragmatic considerations regarding the impact of the previous results at hand (e.g., extremely specific previous results)
Do You See What I See? Longitudinal Associations Between Mothers’ and Adolescents’ Perceptions of Their Relationship and Adolescent Internalizing Symptoms
This 6-year community study examined how discrepancies in mothers’ and adolescents’ perceptions of their relationship were longitudinally associated with adolescent internalizing symptoms, and vice versa. 497 adolescents (57% boys, Mage T1 = 13.03, SDage = 0.46) and their mothers reported in 6 annual waves on conflict and warmth in the mother-adolescent relationship and adolescents reported on their depressive and Generalized Anxiety Disorder (GAD) symptoms. Latent Congruence Models suggested that both adolescent depressive and GAD symptoms significantly predicted higher levels of conflict as well as stronger discrepancies in perceptions of conflict 1-year later. In turn, higher levels of conflict significantly predicted both adolescent depressive and GAD symptoms 1-year later. For warmth, lower levels significantly predicted adolescent depressive symptoms 1-year later. Concluding, these findings suggest (1) more systematic evidence for longitudinal associations between conflict than warmth in the mother-adolescent relationship and adolescent internalizing symptoms; (2) support for a transactional model, including support for both interpersonal scar or symptom-driven effects (concerning both levels of and mother-adolescent discrepancies in conflict) and interpersonal risk or relationship-driven effects (concerning levels of both conflict and warmth); (3) longitudinal effects from adolescent internalizing symptoms to mother-adolescent discrepancies, but not vice versa; and (4) strong consistency in patterns of findings across both adolescent depressive and GAD symptoms, with few differential longitudinal associations with aspects of mother-adolescent relationship quality. Thereby, this study provides a more nuanced understanding of the direction of effects between adolescent internalizing symptoms and both levels of and discrepancies in mothers’ and adolescents’ perceptions of their relationship
Longitudinal Associations Between Depressive Symptoms and Quality of Romantic Relationships in Late Adolescence
While youth with higher levels of depressive symptoms appear to have lower quality romantic relationships, little is known about longitudinal associations for both men and women. Therefore, this study used longitudinal dyadic design to examine both concurrent and longitudinal associations between depressive symptoms and positive as well as negative aspects of romantic relationship quality across two waves one- or two-years apart. The sample consisted of 149 Dutch stable heterosexual couples (149 females and 142 males participated at T1) in a stable romantic relationship in late adolescence with a mean age of 20.43 years old at the first wave. Actor-Partner Interdependence models were used to examine potential bidirectional associations over time between depressive symptoms and romantic relationship quality, above and beyond potential concurrent associations and stability of the constructs over time, from the perspective of both romantic partners. Results consistently indicated that men and women who reported higher levels of depressive symptoms perceived less positive aspects (intimacy and support) and more negative aspects (conflict) in their romantic relationship over time. In addition, unexpectedly, when men and women perceived more positive relationship aspects, their partners reported higher levels of depressive symptoms over time. These findings stress that depressive symptoms can interfere with the formation of high-quality romantic relationships
Polygenic Risk for Major Depression Interacts with Parental Criticism in Predicting Adolescent Depressive Symptom Development
Research has focused more and more on the interplay between genetics and environment in predicting different forms of psychopathology, including depressive symptoms. While the polygenic nature of depressive symptoms is increasingly recognized, only few studies have applied a polygenic approach in gene-by-environment interaction (G × E) studies. Furthermore, longitudinal G × E studies on developmental psychopathological properties of depression are scarce. Therefore, this 6-year longitudinal community study examined the interaction between genetic risk for major depression and a multi-informant longitudinal index of critical parenting in relation to depressive symptom development from early to late adolescence. The sample consisted of 327 Dutch adolescents of European descent (56% boys; Mage T1 = 13.00, SDage T1 = 0.44). Polygenic risk for major depression was based on the Hyde et al. (Nature Genetics, 48, 1031–1036, 2016) meta-analysis and genetic sensitivity analyses were based on the 23andMe discovery dataset. Latent Growth Models suggested that polygenic risk score for major depression was associated with higher depressive symptoms across adolescence (significant main effect), particularly for those experiencing elevated levels of critical parenting (significant G × E). These findings highlight how polygenic risk for major depression in combination with a general environmental factor impacts depressive symptom development from early to late adolescence
Depression Socialization in Early Adolescent Friendships: The Role of Baseline Depressive Symptoms and Autonomous Functioning
There is mixed evidence for depression socialization, a process by which friends affect each other’s level of depressive symptoms. The current study examined whether adolescents’ baseline depressive symptoms and three dimensions of autonomous functioning (autonomy, peer resistance, and friend adaptation) make adolescents more or less sensitive to depression socialization, and how these dimensions of autonomous functioning were connected. In this preregistered, two-wave longitudinal study, participants completed questionnaires on depressive symptoms, autonomy, and peer resistance and participated in a task to assess friend adaptation. Participants were 416 Dutch adolescents (Mage = 11.60, 52.8% girls) across 230 close friend dyads. In contrast to expectations, results showed no significant depression socialization nor significant moderation. Furthermore, autonomy and peer resistance were related but distinct constructs, and not related to friend adaptation. These findings suggest that there is no depression socialization in early adolescence, regardless of level of autonomous functioning
Daily Identity Dynamics in Adolescence Shaping Identity in Emerging Adulthood
According to identity theory, short-term day-to-day identity exploration and commitment processes are the building blocks
for long-term development of stable commitments in emerging adulthood. This key assumption was tested in a longitudinal
study including 494 individuals (43% girls, Mage T1 = 13.31 years, range 11.01–14.86 years) who were followed from
adolescence into emerging adulthood, covering ages 13 to 24 years. In the first five years, adolescents reported on their daily
identity processes (i.e., commitment, reconsideration and in-depth exploration) across 75 assessment days. Subsequently,
they reported on their identity across four (bi-) annual waves in emerging adulthood. Findings confirmed the existence of a
dual-cycle process model of identity formation and identity maintenance that operated at the within-person level across days
during adolescence. Moreover, individual differences in these short-term identity processes in adolescence predicted
individual differences in identity development in emerging adulthood. Specifically, those adolescents with low daily
commitment levels, and high levels of identity reconsideration were more likely to maintain weak identity commitments and
high identity uncertainty in emerging adulthood. Also, those adolescents characterized by stronger daily changes in identity
commitments and continuing day-to-day identity uncertainty maintained the highest identity uncertainty in emerging
adulthood. These results support the view of continuity in identity development from short-term daily identity dynamics in
adolescence to long-term identity development in emerging adulthood
Perceived Parental Support and Psychological Control, DNA Methylation, and Loneliness: Longitudinal Associations Across Early Adolescence
A broad range of factors have been associated with the development of adolescent loneliness. In the family context, a lack of parental support and high levels of parental psychological control have systematically been linked to loneliness. On the biological level, DNA methylation (which is an epigenetic process that suppresses gene expression) is believed to play a role in the development of loneliness. Specifically, high levels of DNA methylation in genes that play an important role in the functioning of the human stress response system are believed to elevate the risk of loneliness. Moreover, DNA methylation levels in these stress-related genes can be influenced by stressful environmental factors, suggesting a potential mediating role of DNA methylation in the association between parenting behaviors and loneliness. The current 3-year longitudinal study is the first study to examine the potential bidirectional longitudinal associations between loneliness, DNA methylation in stress-related genes, and both perceived parental support and psychological control. Furthermore, we explored the potential mediating role of DNA methylation in stress-related genes in the associations between perceived parenting and loneliness. The sample comprised 622 early adolescents (55% girls, M age T1 = 10.77 years, SDage T1 = 0.48) who were followed from Grade 5 to 7. Parental support, psychological control, and loneliness were assessed annually by adolescent self-report questionnaires and DNA methylation was determined from saliva samples. Cross-Lagged Panel Models (CLPM) revealed that higher levels of loneliness predicted lower perceived parental support and higher perceived psychological control over time, as well as higher DNA methylation in some stress-related genes, that is, the glucocorticoid receptor gene (NR3C1) and the brain-derived neurotrophic factor (BDNF). In addition, higher NR3C1 methylation was predictive of lower perceived parental support and higher psychological control over time. No evidence was found for a mediating role of DNA methylation. Overall, our longitudinal findings challenge the current focus on DNA methylation and parenting behaviors as risk factors for adolescent loneliness. Instead, they suggest that the less considered direction of effects, which implies that loneliness predicts DNA methylation and aspects of parenting such as support and psychological control, should receive greater attention in future research
Psychometric Qualities of the Educational Identity Processes Scale (EIPS)
CC BY 4.0In the educational domain, the development of identity becomes especially salient
during school transition phases. To assess the specific identity processes that match
the adolescents’ experiences before and after the school transition, the Educational
Identity Processes Scale (EIPS) was developed. The present study aimed to test the
psychometric qualities of the EIPS by examining its factor structure, the internal and
convergent validity of the identity dimensions, and whether the questionnaire was
measurement invariant over time. The pre-transition version was tested in a Dutch sample
(N = 242 early adolescents) and the post-transition version was tested in a Lithuanian
sample (N = 1,268 mid-adolescents). Findings indicated good psychometric qualities for
both the pre- and post-transition versions of the EIPS. Additionally, context dependencies
were observed, as distance to the transition influenced the meaning of specific identity
processes and determined whether specific processes could be considered as part of
normative development
Daily Identity Dynamics in Adolescence Shaping Identity in Emerging Adulthood: An 11-Year Longitudinal Study on Continuity in Development
According to identity theory, short-term day-to-day identity exploration and commitment processes are the building blocks for long-term development of stable commitments in emerging adulthood. This key assumption was tested in a longitudinal study including 494 individuals (43% girls, Mage T1 = 13.31 years, range 11.01–14.86 years) who were followed fro
