The effects of childhood maltreatment, recent interpersonal and noninterpersonal stress, and HPA-axis multilocus genetic variation on prospective changes in adolescent depressive symptoms: A multiwave longitudinal study

Based on a multiwave, two-year prospective design, this study is the first to examine the extent to which multilocus hypothalamic-pituitary-adrenal axis (HPA axis)-related genetic variants, childhood maltreatment, and recent stress jointly predicted prospective changes in adolescent depressive symptoms. A theory-driven multilocus genetic profile score (MGPS) was calculated to combine the effects of six common polymorphisms within HPA-axis related genes (CRHR1, NR3C1, NR3C2, FKBP5, COMT, and HTR1A) in a sample of Chinese Han adolescents (N = 827; 50.2% boys; Mage = 16.45 ± 1.36 years). The results showed that the three-way interaction of HPA-axis related MGPS, childhood maltreatment and recent interpersonal, but not noninterpersonal, stress significantly predicted prospective changes in adolescent depressive symptoms. For adolescents with high but not low HPA-axis related MGPS, exposure to severe childhood maltreatment predisposed individuals more vulnerable to recent interpersonal stress, exhibiting greater prospective changes in adolescent depressive symptoms. The findings provide preliminary evidence for the cumulative risk mechanism regarding gene-by-environment-by-environment (G × E1 × E2) interactions that underlie the longitudinal development of adolescent depressive symptoms and show effects specific to interpersonal stress.

Dynamic Relations Between Negative News Media Experiences and Mental Distress? Examining Transactional Effects During Times of Health Crises

The current study concentrates on individual's media experiences during public health crises - especially media experiences of fear and issue fatigue regarding COVID-19 news media coverage - and their relationship to mental distress. Specifically, we aim to examine potential transactional effects and ask whether media experiences are only a cause or also a consequence of mental distress throughout a health crisis. Utilizing a three-wave panel survey of German citizens (n  = 856), the study employs two random intercept cross-lagged panel models (RI-CLPMs). RI-CLPMs distinguish stable between-person differences from temporal within-person changes, facilitating a nuanced understanding of transactional dynamics. Our study shows distinct relationships between media experiences and mental distress. While the respondents' experiences of issue fatigue led to subsequent changes in their depressive symptoms, which, in turn, influenced subsequent changes in their issue fatigue at the within-person level, media-related fear experience was strongly associated with depressive symptoms only at the between-person level. Thus, our findings demonstrate a causal transactional relationship between media experiences of issue fatigue and mental distress that evolves over time. Media experiences of fear, however, appear to be a consequence of trait-like differences between individuals rather than a result of intraindividual change.

Associations between forms of aggression and peer victimization: Does prosocial behavior matter?

Relatively little is known regarding factors that may mitigate the strength of the associations between forms of aggressive behavior and peer victimization. The goal of the current study was to investigate prosocial behavior as a moderator of these links over a 2-year period during middle childhood. Participants included 410 third-grade students (53% boys) and their homeroom teachers. Results indicated that prosocial behavior was associated with lower initial levels of victimization, whereas relational aggression was associated with higher initial levels of victimization. Physical aggression predicted more stable patterns of victimization over time, and prosocial behavior moderated the prospective link from relational aggression to peer victimization; specifically, relational aggression predicted decreases in victimization at higher levels of prosocial behavior and more stable patterns over time when levels of prosocial behavior were low. Further, gender differences were observed in the moderating effect of prosocial behavior on the prospective link from physical aggression to peer victimization, such that it served as a risk factor for boys and a protective factor for girls.

Executive functioning as a prospective moderator of the relations between maltreatment in childhood and externalizing symptoms and wellbeing from adolescence to young adulthood

Although childhood maltreatment is associated with externalizing symptoms, not all individuals with these experiences develop externalizing behaviors and some exhibit positive adjustment. To address this multifinality, we used latent growth curve modeling to identify trajectories of (a) externalizing symptoms and (b) subjective wellbeing from late adolescence through young adulthood, determine whether types of childhood maltreatment and domains of executive functioning (EF) are associated with initial levels and growth (slopes) of externalizing symptoms or subjective wellbeing, and investigate whether EF moderates these relations. Participants were youth recruited at ages 10-12 (N = 775; 69% male, 31% female; 76% White, 21% Black/African American, 3% multiracial). We examined EF at ages 10-12, childhood maltreatment reported retrospectively at age 25, and externalizing symptoms and subjective wellbeing at multiple points between ages 16 and 28. Experience of childhood maltreatment and certain EF domains were associated with externalizing symptoms and subjective wellbeing at age 16. EF domains were associated with rate of change in externalizing problems, though not in expected directions. EF variables moderated the relation between maltreatment and initial levels of both outcomes and change in externalizing symptoms. Findings have implications for intervention efforts to mitigate externalizing problems and bolster positive adjustment.

The Effect of Missing Item Data on the Relative Predictive Accuracy of Correctional Risk Assessment Tools

Missing data are pervasive in risk assessment but their impact on predictive accuracy has largely been unexplored. Common techniques for handling missing risk data include summing available items or proration; however, multiple imputation is a more defensible approach that has not been methodically tested against these simpler techniques. We compared the validity of these three missing data techniques across six conditions using STABLE-2007 (N = 4,286) and SARA-V2 (N = 455) assessments from men on community supervision in Canada. Condition 1 was the observed data (low missingness), and Conditions 2 to 6 were generated missing data conditions, whereby 1% to 50% of items per case were randomly deleted in 10% increments. Relative predictive accuracy was unaffected by missing data, and simpler techniques performed just as well as multiple imputation, but summed totals underestimated absolute risk. The current study therefore provides empirical justification for using proration when data are missing within a sample.

Identifying Trajectories of Change in Burnout Symptoms of Gaelic Games Athletes Over Two Consecutive Seasons

Athlete burnout is conceptualized as an enduring multidimensional syndrome, and longitudinal research is essential to understanding its development over time. However, much of the existing work has been limited to a small number of timepoints (≤3) or short intervals between waves (≤3 weeks), which fail to account for the chronic and complex nature of the syndrome. This study aimed to address these limitations by tracking burnout in adult athletes at 6 timepoints over a 21-month period for the first time. Data from 207 Gaelic games athletes were included in latent growth analysis to compare burnout trajectories of increasing complexity. A linear model best described all burnout symptoms. On average over the 21-month period, feelings of exhaustion declined, sport devaluation increased, and reduced accomplishment remained stable. Findings provide important insight into potential high-risk periods in the season and can help to inform targeted intervention or prevention efforts.

Prenatal chronic inflammation and children's executive function development

Fetal inflammation, typically measured indirectly through prenatal maternal cytokine markers, has been shown to impact early childhood executive functions (EFs), which are central to later cognitive and life outcomes. Here, we assessed the impact of prenatal inflammation on EF developmental trajectories using direct placenta histopathology measures in 131 mothers who predominantly self-identified as Black (90.8% Black; 0.8% Asian American, 1.5% biracial, 0.8% Latinx, 3.1% White, 3.1% Missing). We found that placental measures of inflammation were associated with limited gain in EF development from 3 to 5 years old. In follow up analyses, we addressed whether screening questionnaires in infancy might aid in classification of infants as higher risk for subsequent EF problems. We found that parent responses to the Ages & Stages Questionnaire and the Infant/Toddler Sensory Profile at 12 months predict the development of EF abilities in children exposed to chronic inflammation. These findings open promising opportunities for early screening of children at risk for poor executive functioning in children exposed to prenatal inflammation.

Examining processes of change for acceptance and commitment therapy and cognitive behavioral therapy self-help books with depressed college students

Given the prevalence of depression, it is worthwhile to consider a variety of treatment approaches to reach as many sufferers as possible, including highly accessible formats such as self-help books. Books based in acceptance and commitment therapy (ACT) and cognitive behavioral therapy (CBT) propose to treat depression through distinct processes of change, though the degree to which these treatments are distinguishable in this format is unclear. Furthermore, it is possible that some individuals may respond better to therapeutic processes from one approach over the other based on personal preferences. We tested the effects of ACT and CBT self-help books on processes of change in a sample of 139 depressed college students in which some participants were given a choice of treatment and others were randomized. Cognitive fusion, which improved better in the ACT group, was the only process of change that distinguished the two treatments. Additionally, early improvements in cognitive fusion were associated with less depression-related stigma at posttreatment. Lastly, randomization, instead of choosing a treatment, led to greater improvements in almost all processes of change. We discuss how these findings inform personalized care, tangible differences between ACT and CBT, and effective practices for treating depression at large scale.

Dealing with missing data in multi-informant studies: A comparison of approaches

Multi-informant studies are popular in social and behavioral science. However, their data analyses are challenging because data from different informants carry both shared and unique information and are often incomplete. Using Monte Carlo Simulation, the current study compares three approaches that can be used to analyze incomplete multi-informant data when there is a distinction between reference and nonreference informants. These approaches include a two-method measurement model for planned missing data (2MM-PMD), treating nonreference informants' reports as auxiliary variables with the full-information maximum likelihood method or multiple imputation, and listwise deletion. The result suggests that 2MM-PMD, when correctly specified and data are missing at random, has the best overall performance among the examined approaches regarding point estimates, type I error rates, and statistical power. In addition, it is also more robust to data that are not missing at random.

Caregiver-reported infant motor and imitation skills predict M-CHAT-R/F

Altered motor and social-communicative abilities in infancy have been linked to later ASD diagnosis. Most diagnostic instruments for ASD cannot be utilized until 12 months, and the average child is diagnosed substantially later. Imitation combines motor and social-communicative skills and is commonly atypical in infants at risk for ASD. However, few measures have been developed to assess infant imitation clinically. One barrier to the diagnostic age gap of ASD is accessibility of screening and diagnostic services. Utilization of caregiver report to reliably screen for ASD mitigates such barriers and could aid in earlier detection. The present study developed and validated a caregiver-report measure of infant imitation at 4, 6, and 9 months and explored the relationship between caregiver-reported imitation and motor abilities with later ASD risk. Participants (N = 571) were caregivers of term and preterm infants recruited as part of a large multi-site study of PediaTrac™, a web-based tool for monitoring and tracking infant development. Caregivers completed online surveys and established questionnaires on a schedule corresponding to well-child visits from birth to 18 months, including the M-CHAT-R/F at 18 months. Distinct imitation factors were derived from PediaTrac at 4, 6, and 9 months via factor analysis. The results supported validity of the imitation factors via associations with measures of infant communication (CSBS; ASQ). Imitation and motor skills at 9 months predicted 18-month ASD risk over and above gestational age. Implications for assessment of infant imitation, detecting ASD risk in the first year, and contributing to access to care are discussed.

Developmental Trajectories of Mental Health in Chinese Early Adolescents: School Climate and Future Orientation as Predictors

There is growing support for the dual-continua model of mental health, which emphasizes psychopathology and well-being as related but distinct dimensions. Yet, little is known about how these dimensions co-develop from childhood to early adolescence and what factors predict their different trajectories. The current study aimed to identify distinct patterns of mental health in Chinese early adolescents, focusing on both psychopathological symptoms (i.e., depressive symptoms and self-harm behaviors) and subjective well-being (i.e., life satisfaction and affect balance). This study also examined the contributions of school climate and future orientation to these trajectories. A total of 1,057 students (Mage = 11.88, SDage = 1.67; 62.1% boys) completed four assessments over two years, with six-month intervals. Using parallel-process latent class growth modeling, we identified four groups: Flourishing (32.5%), Languishing (43.8%), Troubled with Stable Depressive Symptoms (16.1%), and Troubled with Increasing Self-Harm Risk (7.6%). Furthermore, school climate and future orientation contributed to adolescents' membership in these trajectories, either independently or jointly. Specifically, higher levels of future orientation combined with higher school climate were associated with a lower likelihood of belonging to the Troubled with Increasing Self-Harm Risk trajectory, compared to the Flourishing group. Our findings identified four distinct mental health trajectories consistent with the dual-continua model, and demonstrated that the development of psychopathology and well-being were not always inversely related (e.g., the Languishing group). Adolescents with unique developmental profiles may benefit from tailored intervention strategies that build on the personal and environmental assets of the adolescent.

Connecting through touch: Attitudes toward touch in pregnancy are associated with couples' sexual and affectionate behaviors across the transition to parenthood

Touch is a universal nonverbal action often used by romantic partners to demonstrate affection and care for each other. Attitudes toward touch might be particularly relevant across periods of relational strain-such as the transition to parenthood-when couples face many novel stressors and shifting priorities which can interfere with their sexual and affectionate experiences. New parent couples (N = 203) completed self-report measures online across six time-points (two prenatal). We tested whether couples' attitudes toward touch (touch aversion, touch for affection, touch for emotion regulation) at baseline (20 weeks mid-pregnancy) predicted their frequency of sexual and affectionate behaviors from mid-pregnancy through 12-month postpartum. Both partners' more positive attitudes toward touch (i.e., for affection and emotion regulation) and lower aversive attitudes toward touch, as measured in mid-pregnancy, predicted couples' higher frequency and variety of sexual and affectionate behaviors at 3-month postpartum. Touch attitudes generally did not predict the degree of change in the frequency or variety of sexual or affectionate behaviors, with one exception: non-birthing parents' more positive attitudes toward touch for emotion regulation in mid-pregnancy predicted a slower decline in couples' affectionate behaviors across pregnancy. Findings underscore a link between new parents' attitudes toward touch and their subsequent sexual and affectionate behaviors, particularly in the early postpartum period. New parents need to navigate novel sexual changes and a nonverbal strategy such as touch might be useful to promote intimacy and care.

Using Monte Carlo Simulation to Forecast the Scientific Utility of Psychological App Studies: A Tutorial

Mobile applications offer a wide range of opportunities for psychological data collection, such as increased ecological validity and greater acceptance by participants compared to traditional laboratory studies. However, app-based psychological data also pose data-analytic challenges because of the complexities introduced by missingness and interdependence of observations. Consequently, researchers must weigh the advantages and disadvantages of app-based data collection to decide on the scientific utility of their proposed app study. For instance, some studies might only be worthwhile if they provide adequate statistical power. However, the complexity of app data forestalls the use of simple analytic formulas to estimate properties such as power. In this paper, we demonstrate how Monte Carlo simulations can be used to investigate the impact of app usage behavior on the utility of app-based psychological data. We introduce a set of questions to guide simulation implementation and showcase how we answered them for the simulation in the context of the guessing game app Who Knows (Rau et al., 2023). Finally, we give a brief overview of the simulation results and the conclusions we have drawn from them for real-world data generation. Our results can serve as an example of how to use a simulation approach for planning real-world app-based data collection.

Trajectories of adaptive functioning from early childhood to adolescence in autism: Identifying turning points and key correlates of chronogeneity

Background

Previous research has demonstrated heterogeneous adaptive outcomes across the autism spectrum; however, the current literature remains limited in elucidating turning points and associated factors for longitudinal variability (chronogeneity). To address these empirical gaps, we aimed to provide a finer-grained characterization of trajectories of adaptive functioning from early childhood to adolescence in autism.

Methods

Our sample (N = 406) was drawn from an inception cohort of children diagnosed Autistic at ages 2-5. Adaptive functioning was assessed with Vineland Adaptive Behavior Scales (VABS, 2nd Edition) across 6 visits from the time of diagnosis by age 18. Parallel-process latent growth curve modeling were used to estimate domain-level VABS trajectories, followed by latent class growth analysis to identify trajectory subgroups. Child characteristics at diagnosis, family demographics, and participation outcomes at adolescence were compared across subgroups.

Results

Piecewise latent growth models best described VABS trajectories with two turning points identified at around ages 5-6 and 9-10, respectively reflecting transitions into school age and early adolescence. We parsed four VABS trajectory subgroups that vary by level of functioning and change rate for certain domains and periods. Around 16% of the sample exhibited overall adequate functioning (standard score >85) with notable early growth and social adaptation during adolescence. About 21% showed low adaptive functioning (standard score ≤70), with decreasing slopes by age 6 followed by improvements in communication and daily-living skills by age 10. The other two subgroups (63% in total) were characterized by adaptive functioning between low and adequate levels, with relatively stable trajectories entering school age. These subgroups differed most in their cognitive ability at diagnosis, household income, and social participation in adolescence.

Conclusions

We identified key individual and family characteristics and time windows associated with distinct adaptive functioning trajectories, which have important implications for providing timely and tailored supports to Autistic people across developmental stages.

Positive school climate and strong school identification as protective factors of adolescent mental health and learning engagement: A longitudinal investigation before and during COVID-19

The COVID-19 pandemic resulted in significant disruptions for children and youth around the world, especially given school closures and shifts in teaching modes (on-line and hybrid). However, the impact of these disruptions remains unclear given data limitations such as a reliance on cross-sectional and/or short-interval surveys as well as a lack of broad indicators of key outcomes of interest. The current research employs a quasi-experimental design by using an Australian four-year longitudinal survey with student responses from Grade 7 to 10 (aged 12-15 years old) (N = 8,735 from 20 schools) in one education jurisdiction. Responses are available pre-pandemic (2018 and 2019) and during the pandemic (2020 and 2021). Importantly the survey included measures of well-being, mental health and learning engagement as well as potential known school-environment factors that could buffer against adversity: school climate and school identification. The findings were generally in line with key hypotheses; 1) during COVID-19 students' learning engagement and well-being significantly declined and 2) students with more positive school climate or stronger school identification pre-COVID-19 fared better through the disruption of the pandemic. However, these same students suffered from a steeper decline in well-being and engagement which may be explained through the impact of losing meaningful social or group connections. This decline was evident after controlling for gender, academic grade (as a proxy of age), parental education, and socioeconomic status. It is concluded that investing in the social environment of schools is important in crisis preparedness and can facilitate better crisis response among youth.

Learning strategies and reading achievement in primary schools: Longitudinal relationship and gender differences

BACKGROUND

Learning is a self-regulated loop where learning strategies and achievements are interrelated. In reading, although some studies have explored the relationship between different learning strategies (memorization, elaboration and control) and reading achievement, little is known about how they interact over time. Even though the longitudinal relationship was revealed in some studies, most of the evidence was based on the whole population, regardless of gender differences.

AIMS

This study was designed to examine the longitudinal relationship between memorization, elaboration, control strategies and reading achievement, as well as the gender difference in the longitudinal relationship.

SAMPLE

The sample consisted of 3878 Chinese students (2025 boys, 1853 girls) who were surveyed in Grade 4 and Grade 6.

METHODS

A cross-lagged model was conducted to examine the longitudinal relationship between memorization, elaboration, control strategies and reading achievement while controlling for gender, age and parents' educational levels. Multigroup cross-lagged models were conducted to examine gender differences in the longitudinal relationship between these variables.

RESULTS

Memorization and elaboration strategies were reciprocally related. Both predicted subsequent control strategies, but not vice versa. Only memorization strategies positively predicted subsequent reading achievement, while prior reading achievement positively predicted the subsequent three strategies. The effects of prior reading achievement on subsequent learning strategies were stronger for boys.

CONCLUSIONS

Memorization strategies play a prominent role in promoting deeper strategies and reading achievement in Chinese primary schools, which might relate to culture and developmental stages. Higher achievement or positive feedback from learning results might be motivation for using different strategies, especially for boys.

Childhood maltreatment, multilocus HPA-axis genetic variation and adolescent comorbidity profiles of depressive and anxiety symptoms

BACKGROUND

Despite a growing body of evidence showing both genetic and environmental influences on adolescent depression and anxiety, the involved comorbid mechanisms regarding gene-by-environment (G × E) interaction remain unclear.

OBJECTIVE

The current study was the first to investigate the extent to which multilocus hypothalamic-pituitary-adrenal (HPA)-axis genetic variants moderated the association between childhood maltreatment and adolescent comorbid depression and anxiety.

METHODS

The participants were 827 Chinese Han adolescents (Mage = 16.45 ± 1.37 years; 50.2 % girls). A theory-driven multilocus genetic profile score (MGPS) was computed by calculating alleles of core HPA-axis genes (CRHR1, NR3C1, NR3C2, and FKBP5) associated with heightened stress reactivity. Childhood maltreatment was retrospectively collected using Childhood Trauma Questionnaire. Comorbidity profiles of self-reported adolescent depressive and anxiety symptoms were constructed via person-centered latent profile analysis.

RESULTS

Three heterogeneous comorbidity profiles of depressive and anxiety symptoms were identified: comorbid severe symptoms (9.7 %), comorbid moderate symptoms (46.4 %) and comorbid mild symptoms (43.9 %). The HPA-axis related MGPS significantly interacted with childhood maltreatment, especially emotional maltreatment (emotional abuse: OR = 1.14, 95 % CI [1.03, 1.26], p < .01; emotional neglect: OR = 1.07, 95 % CI [1.01, 1.13], p < .05), to distinguish the comorbid severe symptoms profile from the comorbid mild symptoms profile (OR = 1.03, 95 % CI [1.01, 1.06], p < .05).

CONCLUSION

The HPA-axis related genes showed an additive polygenic sensitivity toward childhood maltreatment, which might be one of the polygenic G × E mechanisms underlying adolescent comorbid depression and anxiety.

Longitudinal relations between theory of mind and academic achievement among deaf and hard-of-hearing school-aged children

This 2-year longitudinal study investigated the bidirectional relations between the development of theory of mind (ToM) and academic competences in a sample of 270 deaf and hard-of-hearing (DHH) children (Mage at Wave 1 = 7.52 years, SD = 0.99; 58.5% boys and 41.5% girls). Across three waves (10 months apart), children were assessed for their ToM abilities, using the ToM scale and a second-order false belief task, as well as for their language and mathematics skills. Cross-lagged correlational analysis revealed significant bidirectional associations between ToM and academic achievement (language and mathematics). That is, ToM predicted academic achievement with similar strength as ToM development itself was predicted by academic achievement. Our results highlight the bidirectional nature of the association between ToM and academic achievement, and they show that ToM development plays a crucial role in DHH children's school functioning.

Are Family Factors Differentially Associated with Externalizing Symptoms Among Youth with Perinatally Acquired HIV?

Youth with perinatally-acquired HIV (PHIV) face unique psychosocial stressors. They are at risk for externalizing problems, including symptoms of oppositional defiant disorder, conduct disorder (CD), and attention-deficit/hyperactivity disorder (ADHD), as well as risk-taking behaviors, such as substance use (SU). Although family factors have been differentially associated with externalizing and SU behaviors based on youth sex in prior research, there is a dearth of literature considering these processes among youth with PHIV. Participants included 314 youth with PHIV (M = 12.88 years, SD = 3.08 years; 50.80% male; 85.30% Black or Latinx). Boys exhibited higher levels of ADHD symptoms than girls. Among boys, lower levels of consistency in discipline were associated with higher CD symptoms. Lower levels of family cohesion were associated with higher levels of SU among girls, and higher levels of CD symptoms across youth sex. Findings support the need for family-focused behavioral interventions among youth with PHIV.

Longitudinal Relationships Between Help-Seeking Intentions and Depressive Symptoms in Adolescents

PURPOSE

Cross-sectional studies have shown an association between lower help-seeking intentions and greater depressive symptoms among adolescents. However, no longitudinal study has examined the direction of this association. The current study investigated whether help-seeking intentions and depressive symptoms are reciprocally associated at the within-person (individual) level during early to mid-adolescence.

METHODS

Longitudinal data on help-seeking intentions and depressive symptoms in adolescents were obtained from a population-based birth cohort study (Tokyo Teen Cohort; N = 3,171) at four time points (10y, 12y, 14y, and 16y). A random intercept cross-lagged panel model was used to evaluate the within-person prospective associations between help-seeking intentions and depressive symptoms.

RESULTS

At the within-person level, significant associations were consistently observed between antecedent greater depressive symptoms and subsequent lower help-seeking intentions across all time points (10y-12y: standardized regression coefficient (β) = -0.12, p < .001; 12y-14y: β = -0.07, p < .05; and 14y-16y: β = -0.09, p < .01). Meanwhile, significant within-person associations were partly observed between antecedent lower help-seeking intentions and subsequent greater depressive symptoms from 10y to 12y (β = -0.07, p < .05) and from 14y to 16y (β = -0.12, p < .001). These prospective associations were almost the same when adjusted for the number of potential confidants as a time-varying confounder.

DISCUSSION

Adolescents with worsening depressive symptoms may become increasingly reluctant to seek help over time. Proactive early recognition and intervention with support from parents, teachers, and other individuals may facilitate the management of depression in adolescents.

The genetics of gaming: A longitudinal twin study

Background

Gaming is a popular past-time activity among children and adolescents, but it there is also a possible link to negative consequences such as psychological distress and lowered academic achievement. However, there are fundamental knowledge gaps remaining regarding central characteristics of gaming such as heritability, stability over time, and sex differences. We examined the genetic and environmental contribution to gaming behavior, including sex differences, continuity and change, in a longitudinal cohort of twins.

Methods

This is the first longitudinal twin study on gaming, involving 32,006 twins in Sweden. Parents were asked about the twins' gaming at ages 9, 15 and 18. We used univariate and multivariate twin analyses to estimate the relative contribution of genetic and environmental influences at each time-point as well as across time. Sex-differences were also explored.

Results

The results showed large sex differences, where genetics explained more of the variance for boys (31.3%-62.5% depending on age) than for girls (19.4%-23.4%). Genetic factors explained an increasing amount of the variance for boys (31.3% at age 9, 62.5% at age 15 and 53.9% at age 18). Shared environmental factors explained a larger proportion of the variance among girls, which remained relatively stable over time (70.5% at age 9, 61.8% at age 15 and 60.5% at age 18). The results also indicated that most of the variance came from genetic and environmental sources specific to each age.

Conclusions

Compared to many other behavioral phenotypes, such as gambling, gaming was relatively unstable with a large degree of genetic innovation. There were large sex differences in the contribution of genetic and environmental factors. This suggests that excessive gaming could be the result of age- and sex-specific genetic and environmental factors, and should be taken into account when mapping gaming behaviors, since these behaviors might be under continual etiological transformation.

Enhancing Tobacco Quitline Outcomes for African American Adults: An RCT of a Culturally Specific Intervention

INTRODUCTION

This study tested the effectiveness of a culturally specific tobacco cessation video intervention among African American quitline enrollees.

STUDY DESIGN

This was a 3-arm semipragmatic RCT.

SETTING/PARTICIPANTS

African American adults (N=1,053) were recruited from the North Carolina tobacco quitline and data were collected between 2017 and 2020.

INTERVENTION

Participants were randomized to receive (1) quitline services only; (2) quitline services plus a standard, general audience video intervention; or (3) quitline services plus Pathways to Freedom (PTF), a culturally specific video intervention designed to promote cessation among African American persons.

MAIN OUTCOME MEASURES

The primary outcome was self-reported 7-day point prevalence smoking abstinence at 6 months. Secondary outcomes included 7-day and 24-hour point prevalence abstinence at 3 months, 28-day continuous abstinence, and intervention engagement. Data analyses occurred in 2020 and 2022.

RESULTS

At 6 months, 7-day point prevalence abstinence was significantly greater in the Pathways to Freedom Video arm compared with quitline-only (OR=1.5, CI=1.11, 2.07). Twenty four-hour point prevalence abstinence was significantly greater in the Pathways to Freedom (than in quitline-only) group at 3 (OR=1.49, 95% CI=1.03, 2.15) and 6 (OR=1.58, 95% CI=1.10, 2.28) months. At 6 months, 28-day continuous abstinence (OR=1.60, 95% CI=1.17, 2.20) was significantly greater in the Pathways to Freedom Video arm than in the quitline-only arm. Views of the Pathways to Freedom Video were 76% higher than views of the standard video.

CONCLUSIONS

Culturally specific tobacco interventions delivered through state quitlines can increase cessation and thus have the potential to decrease health disparities among African American adults.

Detection of atypical response trajectories in biomedical longitudinal databases

Many health care professionals and institutions manage longitudinal databases, involving follow-ups for different patients over time. Longitudinal data frequently manifest additional complexities such as high variability, correlated measurements and missing data. Mixed effects models have been widely used to overcome these difficulties. This work proposes the use of linear mixed effects models as a tool that allows to search conceptually different types of anomalies in the data simultaneously.

Investigating associations between parent engagement and toddlers' mathematics performance

Early mathematics skills relate to later mathematics achievement and educational attainment, which in turn predict career choice, income, health and financial decision-making. Critically, large differences exist among children in early mathematics performance, with parental mathematics engagement being a key predictor. However, most prior work has examined mothers' mathematics engagement with their preschool- and school-aged children. In this Registered Report, we tested concurrent associations between mothers' and fathers' engagement in mathematics activities with their 2- to 3-year-old toddlers and children's mathematics performance. Mothers and fathers did not differ in their engagement in mathematics activities, and both parents' mathematics engagement related to toddlers' mathematics skills. Fathers' mathematics engagement was associated with toddlers' number and mathematics language skills, but not their spatial skills. Mothers' mathematics engagement was only associated with toddlers' mathematics language skills. Critically, associations may be domain-specific, as parents' literacy engagement did not relate to measures of mathematics performance above their mathematics engagement. Mothers' and fathers' mathematics activities uniquely relate to toddlers' developing mathematics skills, and future work on the nuances of these associations is needed.

Developmental patterns of children's shyness: Relations with physiological, emotional, and regulatory responses to being treated unfairly

The dysregulation of social fear has been widely studied in children's shyness, but we know little about how shy children regulate during unfair treatment. We first characterized developmental patterns of children's shyness (N = 304, ngirls  = 153; 74% White, 26% Other) across 2 (Mage  = 2.07), 3 (Mage  = 3.08), 4 (Mage  = 4.08), and 6 (Mage  = 6.58) years of age. Data collection occurred from 2007 to 2014. At age 6, the high stable group had higher cardiac vagal withdrawal and lower expressed sadness and approach-related regulatory strategy than the low stable group when being treated unfairly. Although shy children may be more physiologically impacted by being treated unfairly, they may mask their sadness to signal appeasement.

The Indirect Effect of Avoidant Motives for Sex on the Pathways From Childhood Maltreatment to Risky Sex Behaviors

Literature supports a strong link between engagement in risky sex and childhood maltreatment, with engagement in risky sexual behavior proposed as a manifestation of avoidant coping. Sex motives refer to underlying motivations for engaging in sex such as increased intimacy, or peer pressure. Limited research has examined the role of sex motives on the relationship between childhood maltreatment and risky sex. This study sought to examine this path between childhood maltreatment types and later engagement in risky sex through sex motivations that seek to avoid or reduce negative affect (i.e., sex to cope and sex to affirm self-esteem). A sample of sexually active undergraduate women (n = 551) completed a series of questionnaires on childhood maltreatment, risky sexual behavior, and motivations for sexual intercourse as part of a larger parent study on revictimization. Path analysis was conducted to examine differential indirect effects of childhood maltreatment on risky sex (i.e., sex with a stranger and hookup behaviors). Results suggested sex to cope with negative affect mediated the relationship between emotional abuse, sexual abuse, physical neglect, and hookup behavior. Only an indirect path between childhood emotional abuse and sex with a stranger was identified through sex to cope. Emotional abuse was the only maltreatment to predict sex to affirm, but sex to affirm did not predict risky sex outcomes. Findings provide support for differential pathways from various forms of childhood maltreatment, specifically sexual abuse, emotional abuse, and physical neglect, to increased risky sex as a manifestation of avoidant coping. Furthermore, results support the call for more inclusion of nonsexual forms of childhood maltreatment in studies of risky sex and avoidant coping as a potential intervention target for risky sexual behavior regardless of childhood maltreatment type.

Associations between New Mothers' Partner-Oriented Sexual Values and Sexual Distress in the Transition to Parenthood

Women commonly experience heightened sexual distress in pregnancy and postpartum, and there is limited knowledge of protective factors. Women report declines in the importance of sexuality during this time, suggesting that valuing sexuality could be a relevant individual difference factor. It may be particularly protective for women to feel successful in living in line with their sexual values. In a longitudinal study, we examined associations between the extent to which women valued their role as a sexual partner, and their success living in line with this partner-oriented sexual value, with their sexual distress. Women (N = 367) reported the importance of their role as a sexual partner, success living according to this value, and sexual distress during pregnancy (18-20 weeks) and at 3, 6, 12 and 24-months postpartum. More strongly valuing one's role as a sexual partner was associated with more sexual distress, both between-person (i.e., across women) and within-person (i.e., variation within women over time). Above and beyond these effects, greater success at living in line with one's partner-oriented sexual value was associated with less sexual distress. Finding ways to live in line with one's sexual values may protect against sexual distress for new mothers in the transition to parenthood.

Sexual growth and destiny beliefs: Longitudinal associations with dyadic coping among couples seeking medically assisted reproduction

BACKGROUND

Medically assisted reproduction is a vulnerable time for couples' sexual health. Believing that sexual challenges can be worked through (i.e., sexual growth beliefs) or that these challenges indicate incompatibility (i.e., sexual destiny beliefs) may be related to dyadic coping-the strategies couples use to cope-with the physical and psychological stressors of medically assisted reproduction.

AIM

In the current study we aimed to examine the longitudinal associations between typical (i.e., average) levels of sexual growth and destiny beliefs and positive and negative facets of dyadic coping and how greater than typical levels of these constructs predicted each other across time.

METHODS

Couples (n = 219) seeking medically assisted reproduction were recruited for an online longitudinal, dyadic study.

OUTCOMES

Couples completed online measures of sexual growth and destiny beliefs and positive and negative dyadic coping at baseline, 6-and 12-months.

RESULTS

Random intercept cross-lagged panel models demonstrated that at the within-person level, reporting higher sexual growth beliefs at baseline, relative to their average across time points, was associated with lower negative dyadic coping at 6 months. Higher negative dyadic coping at 6 months, relative to their average, was linked to lower sexual growth beliefs at 12-months. When individuals reported higher sexual destiny beliefs at 6-months, relative to their average, they and their partners reported higher negative dyadic coping at 12 -months. At the between-person level, higher overall levels of sexual destiny beliefs were related to higher overall levels of negative dyadic coping. No associations with positive dyadic coping were identified.

CLINICAL IMPLICATIONS

Couples may benefit from identifying and reducing unhelpful beliefs about sex and negative dyadic coping.

STRENGTHS AND LIMITATIONS

Strengths of this study include our large, inclusive sample, engagement of community partners, and novel analytical approach to assess change over time. However, following couples in 6-month increments and not using questionnaires specific to medically assisted reproduction may have limited our ability to detect nuanced changes that couples experience during this time.

CONCLUSION

Lower sexual growth and higher sexual destiny beliefs may promote couples' engagement in less adaptive coping behaviors as they seek medically assisted reproduction.

Early-life adversity is associated with poor iron status in infancy

Exposure to early-life adversity (ELA) and iron deficiency early in life are known risk factors for suboptimal brain and socioemotional development. Iron deficiency may arise from and co-occur with ELA, which could negatively affect development. In the present study, we investigated whether ELA is associated with iron deficiency in infants receiving no iron supplementation. This study is a secondary analysis of extant data collected in the 1990s; participants were healthy infants from working-class communities in Santiago, Chile (N = 534, 45.5% female). We measured stressful life events, maternal depression, and low home support for child development during infancy and assessed iron status when the infant was 12 months old. Slightly more than half of the infants were iron-deficient (51%), and 25.8% were iron-deficient anemic at 12 months. Results indicated that ELA was associated with lower iron levels and iron deficiency at 12 months. The findings are consistent with animal and human prenatal models of stress and iron status and provide evidence of the association between postnatal ELA and iron status in humans. The findings also highlight a nutritional pathway by which ELA may impact development and present a nutritionally-focused avenue for future research on ELA and psychopathology.

School climate, school identification and student outcomes: A longitudinal investigation of student well-being

BACKGROUND

Schools are increasingly recognized as key facilitators of child and youth well-being. Much attention has been directed to the school social environment and the areas of school climate or school connectedness/identification. Drawing on the social identity approach and related work, it has been argued that school social identification may be the mechanism or process through which school climate comes to impact individual student functioning (Applied Psychology, 28, 2009, 171). Much of the previous research on social identity and well-being, though, is limited because it is cross-sectional.

AIMS, SAMPLE & METHODS

This current study aims to advance understanding of the relationships between school climate, school identification and positive and negative well-being. It adopts a three-wave longitudinal sample of Australian students (N = 6537 wave 3, grades 7-10) and incorporates a range of control variables. Multilevel modelling (MLM) is used to test relationships of interest.

RESULTS AND CONCLUSIONS

In line with predictions, school identification was a significant mediator of the relationship between school climate and the well-being dimensions of positive affect and depression (but not anxiety). The substantial theoretical and practical implications of this research are discussed, including the role of the school social environment in helping young people successfully transition to adulthood.

A prospective study of the relative contribution of adolescent peer support quantity and quality to depressive symptoms

BACKGROUND

During adolescence, peer support has an increasingly important role in identity formation and well-being. Prior research has identified that lack of social support from peers in adolescence is a potent risk factor for depression. Two ways that social support has been operationalized is by the number of one's friends (i.e., 'quantity') and perception of one's network (i.e., 'quality'). Typically, these aspects of peer support are assessed separately.

METHODS

Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 3,857), this study sought to test whether (1) adolescent depression relates to having fewer friends versus lower quality friendships, (2) these aspects of adolescent peer support prospectively predict depression in adulthood, (3) gender moderates the effects of peer support on depression, and (4) these aspects of peer support buffer the effects of stressful life events on depression.

RESULTS

Peer support quality uniquely predicted depression in adolescence and adulthood among both males and females. The effect of peer support quality on depressive symptoms, however, was greater for females than males. By contrast, peer support quantity did not uniquely predict depression for males or females.

CONCLUSIONS

Qualitative aspects of adolescent peer support uniquely contribute to mental health not only in adolescence, but in adulthood as well. Potential processes through which peer support relates to depression are discussed, as well as implications for treatment.

Opening the doors for spillovers: a contingency view of the effects of work from home on the work-home interface

Why do employees experience work from home (WFH) differently? We draw on boundary theory to explain how WFH influences employees' work-home interface. WFH intensity increases negative spillovers (i.e., work-to-home conflict and home-to-work conflict) and positive spillovers (i.e., work-to-home enrichment and home-to-work enrichment) between the work and home domains. Negative spillovers can be mitigated through high-quality work equipment and beneficial spatial conditions at home. Domain centrality predicts who can benefit from increased WFH intensity. We test our theory with a sample of 545 employees, obtained through a two-step random sampling procedure in the city of Munich/Germany during the COVID-19 pandemic. We find that WFH intensity increases work-to-home conflict and home-to-work enrichment, affecting employees' relationship satisfaction and job satisfaction. High-quality work equipment mitigates the detrimental effects of WFH. Employees with a high family centrality can reap benefits of more WFH because they experience more home-to-work enrichment. The simultaneous desirable and detrimental effects of WFH intensity can partly explain why studies have found heterogenous WFH experiences among employees.

The role of psychological flexibility in acceptance-enhanced behavior therapy for trichotillomania: Moderation and mediation findings

Trichotillomania is characterized by recurrent pulling out of one's hair, leading to significant hair loss and accompanied by clinically significant distress and/or functional impairment. The current study used data from a randomized controlled trial comparing the effectiveness of acceptance-enhanced behavior therapy (AEBT) to psychoeducation plus supportive therapy (PST; active control) for trichotillomania in an adult sample. The objectives were to examine the moderating and mediating influence of trichotillomania-specific psychological flexibility in treatment for trichotillomania. Participants with lower baseline flexibility performed better in AEBT than PST in terms of greater symptom reduction and quality of life. Lower baseline flexibility also predicted higher likelihood of disorder recovery in AEBT relative to PST. In addition, relative to PST, symptom reduction in AEBT was mediated by psychological flexibility, controlling for anxiety and depression. These findings suggest that psychological flexibility is a relevant process of change in the treatment of trichotillomania. Clinical implications and directions for future research are discussed.

Potential of cell-free hemoglobin and haptoglobin as prognostic markers in patients with ARDS and treatment with veno-venous ECMO

BACKGROUND

Hemolysis is associated with increased mortality in patients with sepsis, ARDS, or therapy with extracorporeal membrane oxygenation (ECMO). To quantify a critical threshold of hemolysis in patients with ARDS and treatment with veno-venous ECMO, we aimed to identify cutoff values for cell-free hemoglobin (CFH) and haptoglobin (Hp) plasma concentrations associated with a significant increase in ICU mortality.

METHODS

Patients with ARDS admitted to a tertiary ARDS referral center between 01/2007 and 12/2018 and treatment with veno-venous ECMO were included. Cutoff values for mean CFH (mCFH) and mean Hp (mHp) plasma concentrations dividing the cohort into groups with significantly different ICU mortalities were calculated and patient characteristics were compared. A multiple logistic regression model with stepwise backward variable selection was included. In addition, cutoff values for vulnerable relative timespans for the respective CFH and Hp concentrations were calculated.

RESULTS

A quantitative cutoff value of 11 mg/dl for mCFH separated the cohort (n = 442) regarding ICU mortality (mCFH ≤ 11 mg/dl: 38%, [95%-CI: 32.22-43.93] (n = 277) vs. mCFH > 11 mg/dl: 70%, [61.99-76.47] (n = 165), p < 0.001). Analogously, a mHp cutoff value ≤ 0.39 g/l was associated with a significant increase in ICU mortality (mHp ≤ 0.39 g/l: 68.7%, [60.91-75.61] (n = 163) vs. mHp > 0.39 g/l: 38.7%, [33.01-44.72] (n = 279), p < 0.001). The independent association of ICU mortality with CFH and Hp cutoff values was confirmed by logistic regression adjusting for confounders (CFH Grouping: OR 3.77, [2.51-5.72], p < 0.001; Hp Grouping: OR 0.29, [0.19-0.43], p < 0.001). A significant increase in ICU mortality was observed when CFH plasma concentration exceeded the limit of 11 mg/dl on 13.3% of therapy days (≤ 13.3% of days with CFH > 11 mg/dl: 33%; [26.81-40.54] (n = 192) vs. > 13.3% of days with CFH > 11 mg/dl: 62%; [56.05-68.36] (n = 250), p < 0.001). Analogously, a mortality increase was detected when Hp plasma concentration remained ≤ 0.39 g/l for > 18.2% of therapy days (≤ 18.2% days with Hp ≤ 0.39 g/l: 27%; [19.80-35.14] (n = 138) vs. > 18.2% days with Hp ≤ 0.39 g/l: 60%; [54.43-65.70] (n = 304), p < 0.001).

CONCLUSIONS

Moderate hemolysis with mCFH-levels as low as 11 mg/dl impacts mortality in patients with ARDS and therapy with veno-venous ECMO. Furthermore, a cumulative dose effect should be considered indicated by the relative therapy days with CFH-concentrations > 11 mg/dl. In addition, also Hp plasma concentrations need consideration when the injurious effect of elevated CFH is evaluated.

Longitudinal development of well-being among Finnish employees during 2019-2021: Relationships with personality trait profiles

We examined well-being profiles among Finnish employees before and during the COVID-19 pandemic and their links with personality trait profiles. Longitudinal survey data were collected in 2019-2021, and 733 respondents participated in all five surveys. The data were analyzed with a person-centered approach using latent profile analysis (LPA). Measures included burnout, work engagement, psychological distress; and Big Five personality traits. Six well-being profiles: Disengaged, Declined, Engaged, Fluctuated, Stable, and Burned-out, and four personality profiles: Ordinary, Reserved, Resilient, and Overcontrolled were identified. Resilient participants typically belonged to the Engaged well-being profile and Reserved to Burned-out and Fluctuated well-being profiles. Although some separation in developmental well-being profiles existed, overall, well-being was rather stable. Personality trait profiles played a crucial role in maintaining well-being.

Modeling geostatistical incomplete spatially correlated survival data with applications to COVID-19 mortality in Ghana

Survival models which incorporate frailties are common in time-to-event data collected over distinct spatial regions. While incomplete data are unavoidable and a common complication in statistical analysis of spatial survival research, most researchers still ignore the missing data problem. In this paper, we propose a geostatistical modeling approach for incomplete spatially correlated survival data. We achieve this by exploring missingness in outcome, covariates, and spatial locations. In the process, we analyze incomplete spatially-referenced survival data using a Weibull model for the baseline hazard function and correlated log-Gaussian frailties to model spatial correlation. We illustrate the proposed method with simulated data and an application to geo-referenced COVID-19 data from Ghana. There are several disagreements between parameter estimates and credible intervals widths obtained using our proposed approach and complete case analysis. Based on these findings, we argue that our approach provides more reliable parameter estimates and has higher predictive accuracy.

Engagement and Utilization of a Complete Remote Digital Care Program for Musculoskeletal Pain Management in Urban and Rural Areas Across the United States: Longitudinal Cohort Study

BACKGROUND

Musculoskeletal (MSK) conditions are the number one cause of disability worldwide. Digital care programs (DCPs) for MSK pain management have arisen as alternative care delivery models to circumvent challenges in accessibility of conventional therapy. Despite the potential of DCPs to reduce inequities in accessing care, the outcomes of such interventions in rural and urban populations have yet to be studied.

OBJECTIVE

The aim of this study was to assess the impact of urban or rural residency on engagement and clinical outcomes after a multimodal DCP for MSK pain.

METHODS

This study consists of an ad hoc analysis of a decentralized single-arm investigation into engagement and clinical-related outcomes after a multimodal DCP in patients with MSK conditions. Patients were coded according to their zip codes to a specific rural-urban commuting area code and grouped into rural and urban cohorts. Changes in their engagement and clinical outcomes from baseline to program end were assessed. Latent growth curve analysis was performed to estimate change trajectories adjusting for the following covariates: age, gender, BMI, employment status, and pain acuity. Outcomes included engagement, self-reported pain, and the results of the Generalized Anxiety Disorder 7-item, Patient Health Questionnaire 9-item, and Work Productivity and Activity Impairment scales. A minimum clinically important difference (MCID) of 30% was considered for pain.

RESULTS

Patients with urban and rural residency across the United States participated in the program (n=9992). A 73.8% (7378/9992) completion rate was observed. Both groups reported high satisfaction scores and similar engagement with exercise sessions, with rural residents showing higher engagement with educational content (P<.001) and higher program completion rates (P=.02). All groups showed a significant improvement in all clinical outcomes, including pain, mental health, and work productivity, without statistically significant intergroup differences. The percentage of patients meeting the MCID was similar in both groups (urban: 67.1%, rural: 68.3%; P=.30).

CONCLUSIONS

This study advocates for the utility of a DCP in improving access to MSK care in urban and rural areas alike, showcasing its potential to promote health equity. High engagement, satisfaction, and completion rates were noted in both groups, as well as significant improvements in clinical outcomes.

Longitudinal associations between mindfulness and changes to body image in first-time parent couples

Pregnancy and postpartum are associated with declines in body image. Research on postpartum body image focuses almost exclusively on the person who gave birth and studies examining protective factors for postpartum body image are scarce. We assessed 257 new-parent couples from mid-pregnancy to 6-months postpartum to examine whether mindfulness-a recognized contributor to psychological well-being-buffered against declines in both partners' perceptions of mothers' body. Mothers' positive body image and partners' perception of mothers' body were collected at four time-points (second and third trimester; 3- and 6-months postpartum); both partners' mindfulness facets-observing, describing, awareness acting, non-judgement, and non-reactivity-were assessed in the second trimester. Dyadic latent growth curve modeling revealed that both partners' perceptions of mothers' body were positively correlated at all moments; however, mothers' positive body image worsened over time, whereas partners' perception of mothers' body remained stable. Mindfulness facets were positively associated with mothers' positive body image (observe, describe, and non-judging) and fathers' (non-judging) perceptions of mothers' body in pregnancy. Mothers' mindfulness facets (acting with awareness, non-judging) were associated with subsequent trajectories of their own body image. By identifying mindfulness facets as targetable protective factors during pregnancy, these findings have implications for future research and interventions focused on perinatal body image.

Community Violence Exposure and Generalized Anxiety Symptoms: Do Callous-Unemotional Behaviors Moderate this Relation Among Urban Youth?

Community violence exposure (CVE; i.e., direct victimization and witnessed violence) is a major public health concern among youth who reside in low income, urban neighborhoods, who tend to experience CVE chronically and disproportionately. Frequent CVE is associated with generalized anxiety disorder (GAD) symptoms, such as persistent or excessive worry and difficulty concentrating. However, not all youth experiencing CVE exhibit such symptoms. One understudied factor that may moderate this relation is callous-unemotional (CU) behaviors (e.g., behaviors consistent with lack of guilt, low levels of empathy). CU behaviors are associated with lower levels of responsiveness to contextual processes; as such, CU behaviors may be associated with lower levels of GAD symptoms in the context of CVE. However, little research considers CU behaviors and GAD symptoms concurrently. To address this gap, the present study examined associations among witnessed and direct CVE, CU behaviors, and GAD symptoms among low-income, urban youth (N = 104, 50% male, Mage = 9.93 ± 1.22 years old, 95% African-American/Black). Multiple regression analyses indicated teacher-reported CU behaviors moderated the relations between CVE and caregiver-reported GAD symptoms. Post-hoc probing revealed that among youth with higher levels of CVE, higher levels of CU behaviors were associated with elevated GAD symptoms compared to their peers with lower levels of CU behaviors. Youth with lower levels of CU behaviors evidenced moderate levels of GAD symptoms regardless of their levels of CVE. Thus, low-income, urban youth who experience elevated levels of CVE may be at increased risk for co-occurring GAD and CU symptoms.

On the Combined Role of Work Engagement and Burnout Among Novice Nurses: A Longitudinal Person-Centered Analysis

This study examined the profiles taken by global and specific facets of work engagement and burnout among a sample of novice ( M tenure = 3.77 years) nurses ( n = 570; 88.4% females; M age = 29.3 years). This study also investigated the role of psychological need satisfaction in the prediction of profile membership, and the implications of these profiles for attitudinal (job satisfaction), behavioral (in-role and extra-role performance, absenteeism, and presenteeism) and health (perceived health difficulties) outcomes. Latent profile analyses revealed six profiles: High Global Engagement and Low Global Burnout, Moderately High Global Engagement and Moderately Low Global Burnout, Low Dedication and Efficacy and Highly Cynical, Dedicated but Exhausted Burned-Out, Low Efficacy Burned-Out, and Very Low Global Engagement and Very High Global Burnout. Although these profiles were replicated over a 1-year period, profile membership was only weakly stable. The most beneficial outcomes were observed in the High Global Engagement and Low Global Burnout profile, and the most detrimental in the Very Low Global Engagement and Very High Global Burnout profile. Need satisfaction was also associated with profile membership, although associations were stronger for global levels of need satisfaction than for specific levels of autonomy, competence, and relatedness need satisfaction.

Major depression, temperament, and social support as psychosocial mechanisms of the intergenerational transmission of parenting styles

In this three-generation longitudinal study of familial depression, we investigated the continuity of parenting styles, and major depressive disorder (MDD), temperament, and social support during childrearing as potential mechanisms. Each generation independently completed the Parental Bonding Instrument (PBI), measuring individuals' experiences of care and overprotection received from parents during childhood. MDD was assessed prospectively, up to 38 years, using the semi-structured Schedule for Affective Disorders and Schizophrenia (SADS). Social support and temperament were assessed using the Social Adjustment Scale - Self-Report (SAS-SR) and Dimensions of Temperament Scales - Revised, respectively. We first assessed transmission of parenting styles in the generation 1 to generation 2 cycle (G1→G2), including 133 G1 and their 229 G2 children (367 pairs), and found continuity of both care and overprotection. G1 MDD accounted for the association between G1→G2 experiences of care, and G1 social support and temperament moderated the transmission of overprotection. The findings were largely similar when examining these psychosocial mechanisms in 111 G2 and their spouses (G2+S) and their 136 children (G3) (a total of 223 pairs). Finally, in a subsample of families with three successive generations (G1→G2→G3), G2 experiences of overprotection accounted for the association between G1→G3 experiences of overprotection. The results of this study highlight the roles of MDD, temperament, and social support in the intergenerational continuity of parenting, which should be considered in interventions to "break the cycle" of poor parenting practices across generations.

Time spent playing predicts early reading and math skills through associations with self-regulation

Children's play time has declined in recent decades, which could negatively impact early self-regulation-a vital component of school readiness. To date, studies have not fully explored how the time spent playing relates to children's self-regulatory skills, and in turn, their early reading and math competencies. Using data from time diaries and direct assessments of self-regulation, prereading, and math skills, this study examined how minutes spent playing at home predict these skills in a sample of 128 children followed from age four to five. Additionally, it considered whether self-regulation explained links between play time and prereading and math. Results showed that the time spent playing positively related to children's self-regulation. Moreover, through its association with self-regulation, play time had indirect effects on prereading and math skills measured one year later. Results suggest that fostering opportunities for play time during the preschool years may help to boost school readiness skills.

Missing data in bioarchaeology II: A test of ordinal and continuous data imputation

OBJECTIVES

Previous research has shown that while missing data are common in bioarchaeological studies, they are seldom handled using statistically rigorous methods. The primary objective of this article is to evaluate the ability of imputation to manage missing data and encourage the use of advanced statistical methods in bioarchaeology and paleopathology. An overview of missing data management in biological anthropology is provided, followed by a test of imputation and deletion methods for handling missing data.

MATERIALS AND METHODS

Missing data were simulated on complete datasets of ordinal (n = 287) and continuous (n = 369) bioarchaeological data. Missing values were imputed using five imputation methods (mean, predictive mean matching, random forest, expectation maximization, and stochastic regression) and the success of each at obtaining the parameters of the original dataset compared with pairwise and listwise deletion.

RESULTS

In all instances, listwise deletion was least successful at approximating the original parameters. Imputation of continuous data was more effective than ordinal data. Overall, no one method performed best and the amount of missing data proved a stronger predictor of imputation success.

DISCUSSION

These findings support the use of imputation methods over deletion for handling missing bioarchaeological and paleopathology data, especially when the data are continuous. Whereas deletion methods reduce sample size, imputation maintains sample size, improving statistical power and preventing bias from being introduced into the dataset.

Longitudinal trajectories of mental health and loneliness for Australian adolescents with-or-without neurodevelopmental disorders: the impact of COVID-19 school lockdowns

BACKGROUND

The impact of COVID-19 (SARS-CoV-2) pandemic school lockdowns on the mental health problems and feelings of loneliness of adolescents with neurodevelopmental disorders (NDDs) is hypothesized to be greater than that of their non-NDD peers. This two and a half year longitudinal study compared changes in the mental health and loneliness of Western Australian adolescents pre-COVID-19 (November 2018 and April 2019), immediately prior to COVID-19 school lockdowns (March 2020), and post schools reopening (July/August 2020).

METHODS

An age-and-gender matched sample of 476 adolescents with-or-without NDDs completed online assessments for mental health and loneliness.

RESULTS

Adolescents with NDDs reported elevated levels of adverse mental health across all four waves of data collection. These young people experienced little change in mental health problems and feelings of loneliness over time, and any increase during school lockdowns returned to, or fell below pre-COVID-19 levels once schools reopened. In comparison, adolescents without NDDs experienced significant increases from a low baseline in depression symptoms, externalizing symptoms, feelings of isolation, and having a positive attitude to being alone, and evidenced a significant decline in positive mental wellbeing. Quality of friendships were unaffected by COVID-19 school lockdowns for all adolescents regardless of NDD status. Of the adolescents with NDDs, those with Attention-Deficit/Hyperactivity Disorder reported a significant increase in positive mental wellbeing following school lockdowns.

CONCLUSIONS

Adolescents with NDDs emerged relatively unscathed from COVID-19 school lockdowns and the short term impacts associated with these were not maintained over time. These findings should be considered in the context of this study's geographical location and the unpredictability of school lockdowns. Learning to live with school lockdowns into the future may be a critical element for further investigation in the context of interventions.

Associations among socioeconomic status and preschool-aged children's, number skills, and spatial skills: The role of executive function

Extensive literature has documented socioeconomic status (SES) disparities in young children's standardized math achievement, which primarily reflect differences in basic number and arithmetic skills. In addition, growing evidence indicates that direct assessments of executive function (EF) both predict standardized math achievement and mediate SES differences in standardized math tests. However, early spatial skills and children's approximate number system (ANS) acuity, critical components of later math competence, have been largely absent in this past research. The current study examined SES associations with multiple direct assessments of early ANS, cardinality, and spatial skills, as well as standardized math achievement, in a socioeconomically diverse sample of 4-year-old children (N = 149). Structural equation modeling revealed SES effect sizes of .21 for geometric sensitivity skills, .23 for ANS acuity, .39 for cardinality skills, and .28 for standardized math achievement. Furthermore, relations between SES and children's spatial skills, ANS acuity, cardinality, and standardized math skills were mediated by a composite measure of children's EF skills. Implications of pervasive SES disparities across multiple domains of early math development, as well as the mitigating role of EF, are discussed.

Maternal-fetal attachment, parenting stress during infancy, and child outcomes at age 3 years

Maternal-fetal attachment (MFA), a woman's relationship with and affiliative behaviors toward her unborn child, has been linked to near-term infant physical and developmental outcomes. However, further longitudinal research is needed to understand whether the impact of MFA extends past the earliest years of life. The current study explored relationships between MFA and child socioemotional competence and behavior problems at age 3 and whether parenting stress mediated the association between MFA and child outcomes. Data were collected from 221 primarily Black/African-American mothers who completed a scale of MFA during pregnancy. Mothers reported on parenting stress at infant age 7 months and reported on child socioemotional competence and problem behaviors at child age 3 years. In path analyses, MFA was directly associated with child socioemotional competence at age 3 years, but an indirect association between MFA and socioemotional competence via parenting stress was not significant. We also observed a significant indirect association between lower MFA and child internalizing behavior problems via parenting stress that was related to maternal dissatisfaction regarding interactions with her child. Findings suggest that assessing MFA may serve as a means to identify dyads who would benefit from support to promote individual health outcomes.

Measuring students’ learning progressions in energy using cognitive diagnostic models

This study applied cognitive diagnostic models to assess students’ learning progressions in energy. A Q-matrix (i.e., an item attribute alignment table) was proposed based on existing literature about learning progressions of energy in the physical science domain and the Trends in International Mathematics and Science Study (TIMSS) assessment framework. The Q-matrix was validated by expert review and real data analysis. Then, the deterministic inputs, noisy ‘and’ gate (DINA) model with hierarchical relations was applied to data from three jurisdictions that had stable, defined science curricula (i.e., Australia, Hong Kong, and Ontario). The results suggested that the hypothesized learning progression was consistent with the observed progression in understanding the energy concept. We also found similarities in students’ attribute mastery across the three jurisdictions. In addition, we examined the instructional sensitivity of the selected item. We discuss several curriculum-related issues and student misconceptions that may affect students’ learning progressions and mastery patterns in different regions of the world.

Indicators of suicidal outcomes among 6- to 12-year-old treatment seeking youth

Suicide among elementary school-age youth is vastly understudied despite being a major health concern. This study utilized mediation and moderation models to elucidate the nature of risk factors for suicide by examining the effect emotion dysregulation (of anger, sadness, and worry) has on the relation between ADHD symptoms (hyperactivity/impulsivity and inattention) and suicidal outcomes (suicidal behavior and risk for suicide) in children ages 6 to 12. When accounting for sex, age, depressive symptoms, and emotion dysregulation, hyperactivity/impulsivity was positively associated with suicidal behavior; however, inattention was negatively associated with suicidal behavior. After accounting for the variance associated with sex, age, and depressive symptoms, two interaction effects were evident. At low levels of sadness and worry dysregulation, hyperactivity was positively associated with suicide risk. However, at high levels of sadness and worry dysregulation, hyperactivity was not related to suicide risk. Findings support moderation over mediation.

The Mediating Role of Internalizing Problems Between Peer Victimization and Dating Violence Victimization: A Test of the Stress Generation Hypothesis

Peer victimization and dating violence are highly prevalent among adolescents. Those two forms of victimization are notably associated with heightened levels of internalizing problems. The stress generation hypothesis stipulates that depressive cognitions and behaviors may generate interpersonal stressors for depressed individuals. It has thus been hypothesized that victims of peer victimization may experience higher levels of internalizing problems, which in turn, may render them more at risk of experiencing dating violence victimization. We used a longitudinal design with three waves from the Quebec Youth's Romantic Relationships Survey (n = 4,923). Participants (59.6% girls, aged between 14 and 18 years old) reported their experiences of dating violence victimization, peer victimization and psychological distress. A cross-lagged panel analysis was performed to test the mediational effect of psychological distress between peer victimization and dating violence while controlling for age and gender. The interaction effect of gender in the model was also tested. The longitudinal relationship between peer victimization and dating violence victimization was significantly mediated by internalizing problems. This result thus supports the stress generation hypothesis. No interaction effect of gender was observed in the model, thus suggesting that this relationship does not change as a function of gender. This study offers to practitioners in the area of prevention and intervention for peer victimization and dating violence a different way of tackling the problem of revictimization. Indeed, our findings revealed that internalizing problems were longitudinally associated with subsequent relational problems, when occurring after being victimized. Therefore, addressing internalizing problems instead, or in addition to prevention or intervention efforts to stop victimization may help in reducing revictimization rates.
