AbstractActor and partner effects for the 2‐year longitudinal associations between marital adjustment and life satisfaction were evaluated in a population‐based sample of middle‐aged and older adults (N = 1,385 couples). Results showed that (a) higher marital adjustment at baseline predicted higher life satisfaction at follow‐up, (b) higher life satisfaction at baseline predicted higher marital adjustment at follow‐up, (c) marital adjustment more strongly predicted life satisfaction than life satisfaction predicted marital adjustment for women, and (d) higher partner marital adjustment at baseline predicted higher life satisfaction at follow‐up. Results suggest that marital adjustment and life satisfaction influence one another in a bidirectional fashion and that the direction is predominantly from marital adjustment to life satisfaction in women.

Purpose: To identify school typologies based on the availability of play equipment and installations. We also examined the associations between availability of play items and child adiposity. Design: Secondary analysis of longitudinal data. Setting: Elementary schools in Montreal, Canada. Participants: We used data from the Quebec Adipose and Lifestyle Investigation in Youth study (QUALITY), an ongoing investigation of the natural history of obesity and type 2 diabetes in Quebec children of Caucasian descent. Measures: The presence of play items was assessed in each child's school. A trained nurse directly assessed child anthropometric measurements to derive body mass index and waist circumference. Body fat composition was measured using DEXA Prodigy Bone Densitometer System. Analyses: The final analytic sample comprised 512 students clustered in 296 schools (81% response). We used K-cluster analyses to identify school typologies based on the variety of play items on school grounds. Generalized estimation equations were used to estimate associations between school clusters and outcomes. Results: We identified 4 distinct school typologies. Children in schools with the most varied indoor play environments had lower overall body fat, B = −1.26 cm (95% confidence interval [CI], −2.28 to −0.24 cm), and smaller waist circumference, B = −4.42 cm (95% CI, −7.88 to −0.96 cm), compared to children with the least varied indoor play environment. Conclusion: Our results suggest that policies regulating the availability of play items in schools may enrich comprehensive school-based obesity prevention strategies. Extending research in this area to diverse populations is warranted.

Purpose. To examine the relation between dieting and smoking initiation among adolescents. Design. Prospective data from a nationally representative study were used. Setting. Two waves (1994 to 1996) of the National Longitudinal Study of Adolescent Health. Subjects. The sample included 7795 non-Latino Caucasian and non-Latino African-American adolescents. Measures. Dieting status was the independent variable and trying smoking and initiation of regular smoking were the dependent variables. Covariates included age, ethnicity, overweight status, false self-perception about being overweight, and availability of cigarettes at home. Analysis. Logistic regression and latent transition analyses were used. Results. Females had a higher prevalence of dieting (55%) when compared with males (25%). Dieting initiation was a significant predictor for initiation of regular smoking among females (OR = 1.94, p = .010), but not among males. Inactive dieting was a significant predictor among males (OR = 1.74, p = .031), but not among females. Compared to nondieters, initiating and consistent female dieters reported a higher probability of trans itioning to having tried regular smoking, although results from logistic regression suggested that the association between consistent dieting and initiation of regular smoking was not significant. Conclusions. There is a positive relation between initiating dieting and initiating regular smoking among females, but among males it is the inactive dieters who show a positive relationship. Results illustrate the importance of examining the association between dieting and the initiation of regular smoking.

Adolescence is a critical period for sexuality development; this study examined prospective associations between pornography use and sexual aggression using a longitudinal study of middle and high school students surveyed five times across 3 years (mean age = 13.7 years at baseline; 53.2% female; 76.5% White; 21.0% Native American; 88.9% heterosexual). Across waves, 15.7%–29.0% of adolescents had viewed pornography in the past 6 months. Results indicated significant, reciprocal associations between pornography and sexual harassment perpetration that were stronger for male adolescents, and some significant associations between pornography use and subsequent sexual assault perpetration. Findings underscore the need to consider multiple theories of the link between pornography viewing and aggression and need for media literacy sexual education beginning in middle school.

As the most likely primary caregivers, mothers are an integral part of children's social influence and are therefore greatly involved in shaping their children's behaviors. The objectives were to determine the prospective associations between maternal and child diet quality and sedentary behaviors. This study, within the framework of a community-based intervention study, included 1130 children aged 8–10 years and their mothers. The study was carried out during two academic years (2012/2014) with a mean follow-up of 15 months. Exposure and outcome variables were measured at baseline and follow-up, respectively. Diet quality was assessed by the KIDMED questionnaire and the short Diet Quality Screener, respectively. Sedentary behaviors were determined by standardized questions of sedentary behaviors. Maternal consumption of fruits, vegetables, fish, legumes, pasta/rice, dairy products, nuts and baked goods were positively associated (p < 0.05) with the corresponding child behavior. Multiple linear regression models adjusted for sex, age, maternal education and intervention group revealed significant cross-sectional (p < 0.005) and prospective (p < 0.01) associations between maternal and child overall diet quality and sedentary behaviors. Maternal diet quality and sedentary behaviors were predictive for these lifestyle behaviors in children. ; This work was supported by grants from Instituto de Salud Carlos III FEDER, (PI11/01900 and PI20/00199).

This longitudinal study examines whether early experiences with caregivers between the ages of 10 and 12 are associated with later adolescent personality at age 16 using both parent and child reports. Lower positive parenting was prospectively associated with higher neuroticism and lower extraversion and conscientiousness for both parent and self‐reports of personality, as well as lower openness and agreeableness by parent report. Substantiated maltreatment was prospectively associated with greater neuroticism and lower agreeableness and conscientiousness assessed by parent report. Prospective associations were similar across Black and White participants. Positive parenting and, to a lesser extent, a lack of maltreatment were associated with adaptive personality profiles in adolescents, and associations were stronger for parent reports of personality.

Abstract

Aims
Emerging adulthood (i.e. ages 18–25) is a developmental phase associated with frequent alcohol and cannabis use, placing this population at risk for substance use problems. Depression and anxiety (i.e. emotional psychopathology) are also prevalent during this phase, and some emerging adults use substances to cope with these negative emotions. Mindfulness—a multifaceted construct—involves being present in a nonjudgmental and nonreactive way. Certain mindfulness facets are particularly relevant in buffering against substance use. A recent longitudinal study [Single A, Bilevicius E, Johnson EA. et al. (2019) Specific facets of trait mindfulness reduce risk for alcohol and drug use among first-year undergraduate students. Mindfulness 10:1269–1279] showed that specific mindfulness facets (i.e. acting with awareness, nonjudging of inner experience and nonreactivity to inner experience) predicted decreased alcohol and drug use in undergraduates. These pathways were explained by low levels of emotional psychopathology.


Methods
This study expanded this recent work by using a three time-point longitudinal design and by including measures of both alcohol and cannabis use and related problems. Using MTurk, participants (N = 299) completed online measures of trait mindfulness, depression, anxiety, alcohol and cannabis use and related problems at three time-points, each 2 weeks apart. Structural equation modeling was used to test the hypotheses.


Results
The acting with awareness and nonjudging of inner experience facets predicted fewer alcohol problems, but not alcohol use, and this effect was mediated by low levels of emotional psychopathology. These results were not supported for cannabis use and problems.


Conclusion
This study demonstrates that there may be differences in the pathways from trait mindfulness to alcohol and cannabis use during emerging adulthood.

BACKGROUND: Prior investigations have found negative associations between military unit cohesion and posttraumatic stress disorder (PTSD); however, most relied on cross-sectional data and few examined relationships of unit cohesion to other mental disorders. This study evaluates prospective associations of perceived unit cohesion with a range of mental health outcomes following combat deployment. METHODS: US Army soldiers were surveyed approximately 1–2 months before deployment to Afghanistan (T0); and 1 month (T1), 3 months (T2), and 9 months (T3) after return from deployment. Logistic regression was performed to estimate associations of perceived unit cohesion at T0 with risk of PTSD, major depressive episode (MDE), generalized anxiety disorder (GAD), alcohol or substance use disorder (AUD/SUD), and suicidal ideation at T2 or T3 among soldiers who completed all study assessments (N=4,645). Models adjusted for socio-demographic and Army service characteristics, pre-deployment history of the index outcome, and deployment stress exposure. RESULTS: Higher perceived unit cohesion at T0 was associated with lower risk of PTSD, MDE, GAD, AUD/SUD, and suicidal ideation at T2 or T3 (AORs=0.72 to 0.85 per standard score increase in unit cohesion; ps<.05). Models of incidence of mental disorders and suicidal ideation among soldiers without these problems pre-deployment yielded similar results [AORs=0.65 to 0.79; ps<.01], except that perceived unit cohesion was not associated with incident AUD/SUD. CONCLUSIONS: Soldiers who reported strong unit cohesion before deployment had lower risk of post-deployment mental disorders and suicidal ideation. Awareness of associations of perceived unit cohesion with post-deployment mental health may facilitate targeting of prevention programs.

To examine whether cause, severity, and frequency of traumatic brain injury (TBI) increase risk of postdeployment tinnitus when accounting for comorbid posttraumatic stress disorder.Self-report and clinical assessments were done before and after an "index" deployment to Iraq or Afghanistan.Assessments took place on Marine Corps bases in southern California and the VA San Diego Medical Center. Participants were 1647 active-duty enlisted Marine and Navy servicemen who completed pre- and postdeployment assessments of the Marine Resiliency Study. The main outcome was the presence of tinnitus at 3 months postdeployment.Predeployment TBI increased the likelihood of new-onset postdeployment tinnitus (odds ratio [OR] = 1.86; 95% confidence interval [CI], 1.28-2.70). Deployment-related TBIs increased the likelihood of postdeployment tinnitus (OR = 2.65; 95% CI, 1.19-5.89). Likelihood of new-onset postdeployment tinnitus was highest for those who were blast-exposed (OR = 2.93; 95% CI, 1.82-6.17), who reported moderate-severe TBI symptoms (OR = 2.22; 95% CI, 1.22-3.40), and who sustained multiple TBIs across study visits (OR = 2.27; 95% CI, 1.44-4.24). Posttraumatic stress disorder had no effect on tinnitus outcome.Participants who were blast-exposed, sustained multiple TBIs, and reported moderate-severe TBI symptoms were most at risk for new-onset tinnitus.

The present study examined the longitudinal associations among familism respect and obligations values, ethnic centrality and private regard, and ethnic self-identification. Data were drawn from a socioeconomically diverse sample of Latino students attending a predominantly White university. The selection of a White label was associated with less positive private regard, less ethnic centrality, and less strong endorsement of familism respect and obligation values at the start of the academic year compared to those students who selected a national origin label. There was a complex relationship between ethnic identity and familism values over time. Ethnic centrality supported the growth in familism respect values across time, but familism respect values also predicted later growth in ethnic private regard. Our results highlight the fact that ethnic identity processes and familial cultural values can mutually influence each other in emerging adulthood for Latinos.
