Trajectories of mental health problems in childhood and adult voting behaviour:Evidence from the 1970s British Cohort Study

The link between childhood mental health difficulties such as conduct problems and adult political abstention has been overlooked despite early mental health difficulties potentially resulting in political self-marginalisation. Using the1970s British Cohort Study, we estimate developmental trajectories of conduct problems (i.e., from 5 to 16 years). Logistic regression, linear probability models, and propensity score matching were then conducted to test the association between trajectory group membership and voter turnout at 30, 42, and 46 years of age. Three distinct trajectories of conduct problems were identified: a normative (n = 11,871; reference group), moderate-chronic (n = 3433), and elevated-chronic (n = 250) group. Results revealed an association between conduct problems and decreased turnout. In particular the elevated-chronic group had a decreased odds of voting of 52.2%, 52.0%, and 45.7%, as compared to the normative group at 30, 42, and 46 years respectively. The moderate-chronic group had a decreased odds of voting of 24.7% as compared to the normative group at age 30 only. Matched results and linear probability models substantiated findings, suggesting (1) the importance of considering childhood factors when examining antecedents of lifelong voting behaviour, and (2) the political self-marginalisation of people with chronic childhood conduct problems more than 3 decades later.

Maternal warmth and toddler development : support for transactional models in disadvantaged families

Studies support cognitive and social domains of development as entwined in childhood, however, there is a paucity of investigation into the nature of the mother-child relationship within an interdependence framework. Furthermore, the focus on these processes within families from impoverished communities using frequent assessments in early childhood has been limited. Our objectives were to identify (1) the directional associations between toddler's communication ability and social competence, (2) to establish whether the association between toddler's communication ability and social competence is mediated by maternal warmth, and (3) to establish support for transactional models between toddlers' outcomes and maternal warmth in disadvantaged communities in Ireland. Participants included 173 toddlers and their families enrolled in a prenatally commencing prevention programme. Toddler's communication and social competence were assessed at 12, 18, 24 and 36 months and maternal warmth at 6 and 24 months. Cross-lagged models were estimated examining multiple paths of associations simultaneously. Direct and indirect paths of maternal warmth were also examined. Bi-directional associations were found between communication ability and social competence from 12 to 24 months but not thereafter. Maternal warmth did not significantly mediate these associations, however, support of a transactional model was found with social competence. The results support early positive associations between better communication ability and social competence in the first 2 years, however, they suggest that these associations are no longer present by the third year. The role of maternal warmth in fostering social competencies is important for toddlers and equally important is toddler's level of social competence in eliciting increased maternal warmth

Developmental trajectories of aggression, hyperactivity/inattention, and anxious depressed mood:Co-occurring problems within a chilean context

The current study examined multi-trajectories of aggression, hyperactivity/inattention and anxious/depressed problems, along with associated risk factors for trajectory group membership, using a person-centred approach. The sample included 2,857 children (50.1% males) enrolled in the Chilean Encuesta Longitudinal de la Primera Infancia cohort. Maternal reports using the Child Behaviour Checklist (CBCL) were completed when children were three, five and eleven years old. Information on risk/protective factors was collected using maternal reports and standardised assessments when children were aged three. Group-based multi-trajectory analysis was implemented. Results indicated that a five-group model best fit the data, with co-occurring symptoms across domains for all groups. Risk factors for membership of groups with the most elevated risk profiles included child sex, maternal age, single parent status, and maternal education, whilst children’s receptive language, maternal vocabulary skills, and not having early attendance in the educational system emerged as protective factors. These identified risk factors may be important targets for future intervention programmes in the Chilean context.publishedVersio

Systematic Review on the Impact of Different Presentations of Maternal Depression on Children's Socio-Emotional Development

Background: Maternal depression from the perinatal period onwards is associated with an increased likelihood of suboptimal socio-developmental outcomes in offspring, with increasing interest in the extent to which sustained maternal depression impacts on these associations. The current protocol outlines the methodology of a systematic review to synthesise the evidence on the impact of maternal depression from the perinatal period onwards and offspring socio-emotional development, defined as internalising, externalising, and social competence outcomes. We aim to explore the effects of timing, chronicity and severity of maternal depression on outcomes, and identify sources of methodological bias. Methods/Design: The conduct and reporting of the protocol will adhere to PRISMA-P guidelines. The systematic review will be conducted using the following electronic databases: APA PsycInfo, EMBASE, MEDLINE. Grey literature will be searched from the ProQuest Dissertations & Theses Global database. Discussion: Findings from the systematic review will enhance knowledge around potential heterogeneity of timing, chronicity and severity of maternal depression and its impact on offspring socio-emotional development
