We explored the relationship between neighbourhood and social participation among older adults using a Living Environments and Active Aging Framework. This prospective cohort study used baseline data from the Canadian Longitudinal Study on Aging (CLSA) with a 3-year follow-up. Three aspects of social participation were the outcomes; walkability and greenness at baseline were exposure variables. The sample consisted of 50.0% females (n=16,735, age 72.9± 5.6 years). In males, higher greenness was associated with lower loneliness and less variety in social activities. No significant associations between greenness and social participation were found in females. High walkability was related to a higher variety of social activity and higher loneliness in males but not females, and less desire for more social activity in both sexes. Greenness and walkability impact social participation among older adults. Future research should include sex and gender-based analyses.

This study examined associations between pregnancy and infant birth outcomes with child telomere length at age 17 years; and investigated if there are sex differences between pregnancy complications and telomere length. We utilised the population-based prospective Raine cohort study in Western Australia, Australia. 2900 pregnant women were recruited at 16–20 weeks’ gestation (Gen 1), and their children (Gen 2) were followed up over several years. Generalised linear models were used to examine relationships between pregnancy or birth outcomes (gestational diabetes, pre-eclampsia, preterm birth, low birth weight, macrosomia), and as a composite, with telomere length, measured via a DNA sample from blood at 17 years of age. Analyses were adjusted for a range of confounders. Among the 1202 included children, there were no differences in child telomere length for any of the individual maternal or birth weight pregnancy outcomes nor were there any significant interactions between each of the complications (individual or composite) and the sex of the child. However, females born from any of the 5 adverse outcomes had shorter telomeres (estimated mean (SE) = -0.159 (0.061), p = 0.010) than females born in the absence of these complications. Specifically, females born from a pre-eclamptic pregnancy had shorter telomeres than females not born from a pre-eclamptic pregnancy (estimated mean (SE) = -0.166 (0.072), p = 0.022). No relationships were observed in males. Further longitudinal studies are needed to understand mediating factors that are important in predicting offspring telomere length and the necessity to investigate females and males independently.

The rates of anxiety and depression increase across adolescence, many experience recurrence after treatment, yet longitudinal studies examining promotive factors are scarce. We prospectively examined the role of the promotive factors structured style, personal and social competencies, family functioning, and social resources in homotypic and heterotypic continuity and discontinuity of anxiety and depression across three years in a clinical sample. Participants were adolescents with anxiety or depressive disorders aged 13–18 years at T1 (N = 717, 44% initial participation rate) and aged 16–21 years at T2 (N = 549, 80% follow-up participation rate). At T1, diagnoses were collected from medical records and participants responded to questionnaires. At T2, semi-structured diagnostic interviews were conducted. Higher levels of all promotive factors were associated with reduced probability of anxiety or depression three years later. The promotive factors were not associated with homotypic continuity of anxiety, whereas personal competence beliefs, social competence, and, less strongly, family functioning were associated with reduced homotypic continuity of depression and heterotypic continuity from depression to anxiety. Analyses with interaction terms did not indicate moderation by the promotive factors. Our findings suggest that bolstering promotive factors may be vital for increasing treatment success and preventing recurrence of anxiety and depression in the transition toward adulthood.

Children’s externalizing behaviors are associated with impairments across the lifespan. Developmental psychopathology theories propose transactional (bidirectional) associations between child externalizing behaviors and parenting during childhood and adolescence. Yet, these foundational relations in early childhood are not well-studied. Utilizing a large, mixed-sex sample, we examined the reciprocal nature of parenting and child externalizing behaviors across early childhood using robust repeated-measures models. Repeated measures data were drawn from a socioeconomically diverse, longitudinal pregnancy cohort of 1287 (64% Black, 31% White) mother-child dyads at four time points (ages one to six). Three variables were included in cross-lagged panel models: observed parenting quality, child externalizing symptoms, and a maternal risk composite. In covariate-adjusted models, higher parenting quality at Wave 1 predicted lower child externalizing symptoms at Wave 2. Higher externalizing symptoms at Wave 1 and Wave 2 predicted lower parenting quality at Wave 2 and Wave 3, respectively. Maternal risk and parenting quality were not significantly associated. Findings showed both parent-driven and child-driven effects across early childhood that did not vary by child sex. The transactional nature of the parent-child relationship begins in infancy, underscoring the importance of early screening and provision of supports for families to minimize and prevent the development of serious psychopathology.

Attention-deficit hyperactivity disorder (ADHD) and subclinical symptoms of hyperactivity-impulsivity and inattentiveness coincide with an increased risk of peer victimization. What remains unclear are the developmental dynamics of these associations. In a sample drawn from two Norwegian birth cohorts (n = 872; 49.94 % girls), assessed biennially from age 6 to age 14, reciprocal relations between ADHD symptoms and victimization were examined while controlling for symptoms of anxiety and depression. ADHD symptoms were assessed through clinical interviews with parents, whereas victimization was reported by teachers using questionnaires. Random-intercept cross-lagged panel modeling revealed a consistent reciprocal within-person effect of increased ADHD symptoms on victimization, and vice versa. Analyses of subdimensions of ADHD projected a consistent cross-lagged bidirectional relationship between victimization and inattentiveness symptoms only, whereas no such reciprocity was found for hyperactivity-impulsivity symptoms. Results did not differ by gender. Findings suggest that the social context may constitute a vulnerability factor in the etiology of the inattentive subtype of ADHD, and at the same time, that inattentiveness symptoms pose a risk for becoming victimized.

Alexithymia (difficulties identifying and describing feelings) predicts increased risks for psychopathology, especially during the transition from childhood to adolescence. However, little is known of the early contributors to alexithymia. The language hypothesis of alexithymia suggests that language deficits play a primary role in predisposing language-impaired groups to developing alexithymia; yet longitudinal data tracking prospective relationship between language function and alexithymia are scarce. Leveraging data from the Surrey Communication and Language in Education cohort (N = 229, mean age at time point 1 = 5.32 years, SD = 0.29, 51.1% female), we investigated the prospective link between childhood language development and alexithymic traits in adolescence. Results indicated that boys with low language function at ages 4–5 years, and those who later met the diagnostic criteria for language disorders at ages 5–6 years, reported elevated alexithymic traits when they reached adolescence. Parent-reported child syntax abilities at ages 5–6 years revealed a dimensional relationship with alexithymic traits, and this was consistent with behavioral assessments on related structural language abilities. Empirically derived language groups and latent language trajectories did not predict alexithymic traits in adolescence. While findings support the language hypothesis of alexithymia, greater specificity of the alexithymia construct in developmental populations is needed to guide clinical interventions.

The human sciences should seek generalisations wherever possible. For ethical and scientific reasons, it is desirable to sample more broadly than ‘Western, educated, industrialised, rich, and democratic’ (WEIRD) societies. However, restricting the target population is sometimes necessary; for example, young children should not be recruited for studies on elderly care. Under which conditions is unrestricted sampling desirable or undesirable? Here, we use causal diagrams to clarify the structural features of measurement error bias and target population restriction bias (or ‘selection restriction’), focusing on threats to valid causal inference that arise in comparative cultural research. We define any study exhibiting such biases, or confounding biases, as weird (wrongly estimated inferences owing to inappropriate restriction and distortion). We explain why statistical tests such as configural, metric and scalar invariance cannot address the structural biases of weird studies. Overall, we examine how the workflows for causal inference provide the necessary preflight checklists for ambitious, effective and safe comparative cultural research.

Cross-linguistic interactions are the hallmark of bilingual development. Theoretical perspectives highlight the key role of cross-linguistic distances and language structure in literacy development. Despite the strong theoretical assumptions, the impact of such bilingualism factors in heritage-language speakers remains elusive given high variability in children's heritage-language experiences. A longitudinal inquiry of heritage-language learners of structurally distinct languages – Spanish–English and Chinese–English bilinguals (N = 181, Mage = 7.57, measured 1.5 years apart) aimed to fill this gap. Spanish–English bilinguals showed stronger associations between morphological awareness skills across their two languages, across time, likely reflecting cross-linguistic similarities in vocabulary and lexical morphology between Spanish and English. Chinese–English bilinguals, however, showed stronger associations between morphological and word reading skills in English, likely reflecting the critical role of morphology in spoken and written Chinese word structure. The findings inform theories of literacy by uncovering the mechanisms by which bilingualism factors influence child literacy development.

A recent meta-analytic review demonstrated that retrospective assessments of childhood abuse acquired during adulthood – typically via self-report – demonstrate weak agreement with assessments of maltreatment gathered prospectively. The current report builds on prior findings by investigating the agreement of prospectively documented abuse from birth to age 17.5 years in the Minnesota Longitudinal Study of Risk and Adaptation with retrospective, Adult Attachment Interview-based assessments of childhood abuse administered at ages 19 and 26 years. In this sample, an agreement between prospective and retrospective assessments of childhood abuse was considerably stronger (κ = .56) than was observed meta-analytically. Retrospective assessments identified prospectively documented sexual abuse somewhat better than physical abuse, and the retrospective approach taken here was more sensitive to identifying abuse perpetrated by primary caregivers compared to non-caregivers based on prospective records.

Women with breast cancer show dissatisfaction with their appearance, a perception of loss of femininity and bodily integrity, and dissatisfaction with the outcome of the surgery. Body Appreciation (BA) is defined as positive attitudes toward one’s body, beyond satisfaction and dissatisfaction with one’s appearance. Although studies about the protective role of BA have increased, to the best of our knowledge, there are no published studies on the association between BA, body dissatisfaction, and distress in participants with breast cancer. The aims of this study are: (a) To analyze whether BA is a moderator of satisfaction with the body from before breast surgery to the one-year follow-up; and (b) to analyze whether BA is a moderator of distress from before breast surgery to the one-year follow-up. The sample consisted of 115 women diagnosed with breast cancer. Several hierarchical regression analyses were conducted. The results indicated that BA moderated the association between the appearance evaluation before the surgery and the appearance evaluation 12 months after the surgery. Although BA was a significative predictor of distress, it was not a moderator of distress from the moment before breast surgery to the one-year follow-up. This study highlights the importance of evaluating the construct of BA in participants with breast cancer using longitudinal designs and developing psychological interventions that focus on increasing BA.

Reactive and control processes – e.g., negative emotionality and immediacy preference – may predict distinct psychopathology trajectories. However, externalizing and internalizing problems change in behavioral manifestation across development and across contexts, thus necessitating the use of different measures and informants across ages. This is the first study that created developmental scales for both internalizing and externalizing problems by putting scores from different informants and measures onto the same scale to examine temperament facets as risk factors. Multidimensional linking allowed us to examine trajectories of internalizing and externalizing problems from ages 2 to 15 years (N = 1,364) using near-annual ratings by mothers, fathers, teachers, other caregivers, and self report. We examined reactive and control processes in early childhood as predictors of the trajectories and as predictors of general versus specific psychopathology in adolescence. Negative emotionality at age 4 predicted general psychopathology and unique externalizing problems at age 15. Wait times on an immediacy preference task at age 4 were negatively associated with age 15 general psychopathology, and positively associated with unique internalizing problems. Findings demonstrate the value of developmental scaling for examining development of psychopathology across a lengthy developmental span and the importance of considering reactive and control processes in development of psychopathology.

This retrospective cohort study examined prosocial skills development in child welfare-involved children, how intimate partner violence (IPV) exposure explained heterogeneity in children’s trajectories of prosocial skill development, and the degree to which protective factors across children’s ecologies promoted prosocial skill development. Data were from 1,678 children from the National Survey of Child and Adolescent Well-being I, collected between 1999 and 2007. Cohort-sequential growth mixture models were estimated to identify patterns of prosocial skill development between the ages of 3 to 10 years. Four diverse pathways were identified, including two groups that started high (high subtle-decreasing; high decreasing-to-increasing) and two groups that started low (low stable; low increasing-to-decreasing). Children with prior history of child welfare involvement, preschool-age IPV exposure, school-age IPV exposure, or family income below the federal poverty level had higher odds of being in the high decreasing-to-increasing group compared with the high subtle-decreasing group. Children with a mother with greater than high school education or higher maternal responsiveness had higher odds of being in the low increasing-to-decreasing group compared with the low stable group. The importance of maternal responsiveness in fostering prosocial skill development underlines the need for further assessment and intervention. Recommendations for clinical assessment and parenting programs are provided.
