1.  Does Workplace Social Capital Associate with Hazardous Drinking Among Chinese Rural-Urban Migrant Workers? 
PLoS ONE  2014;9(12):e115286.
The present study sought to investigate the associations between workplace social capital and hazardous drinking (HD) among Chinese rural-urban migrant workers (RUMW).
A cross sectional study with a multi-stage stratified sampling procedure was conducted in Shanghai during July 2012 to January 2013. In total, 5,318 RUMWs from 77 workplaces were involved. Work-place social capital was assessed using a validated and psychometrically tested eight-item measure. The Chinese version of Alcohol Use Disorders Identification Test (AUDIT) was used to assess hazardous drinking. Control variables included gender, age, marital status, education level, salary, and current smoking. Multilevel logistic regression analysis was conducted to test whether individual- and workplace-level social capital was associated with hazardous drinking.
Overall, the prevalence of HD was 10.6%. After controlling for individual-level socio-demographic and lifestyle variables, compared to workers in the highest quartile of individual-level social capital, the odds of HD for workers in the three bottom quartiles were 1.13(95%CI: 1.04–1.23), 1.17(95%CI: 1.05–1.56) and 1.26(95%CI: 1.13–1.72), respectively. However, contrary to hypothesis, there was no relationship between workplace-level social capital and hazardous drinking.
Higher individual-level social capital may protect against HD among Chinese RUMWs. Interventions to build individual social capital among RUMWs in China may help reduce HD among this population.

2.  English Proficiency and Peer Interethnic Relations as Predictors of Math Achievement among Latino and Asian Immigrant Students 
Journal of adolescence  2012;35(6):10.1016/j.adolescence.2012.08.002.
Studies show math achievement to be the best predictor of entering post-secondary education. However, less is known about the predictors of math achievement, particularly among immigrant youth. This study examined English proficiency and peer interethnic relations as predictors of mathematics achievement among Latino and Asian high school students, postulating an interaction between the predictors and mediation by academic motivation. A multilevel moderated-mediation model was used to analyze data from a national sample of 2,113 non-native English speaking Latino and Asian students attending high school in the U.S. We found that higher academic motivation mediated the relationship between English proficiency during their sophomore year and gains in senior math achievement scores for both Asian and Latino students. For Latino students however, this indirect path was only significant for students whose perceptions of positive peer interethnic relations at school were average or above average.

3.  Workplace Social Capital and Mental Health among Chinese Employees: A Multi-Level, Cross-Sectional Study 
PLoS ONE  2014;9(1):e85005.
Whereas the majority of previous research on social capital and health has been on residential neighborhoods and communities, the evidence remains sparse on workplace social capital. To address this gap in the literature, we examined the association between workplace social capital and health status among Chinese employees in a large, multi-level, cross-sectional study.
By employing a two-stage stratified random sampling procedure, 2,796 employees were identified from 35 workplaces in Shanghai during March to November 2012. Workplace social capital was assessed using a validated and psychometrically tested eight-item measure, and the Chinese language version of the WHO-Five Well-Being Index (WHO-5) was used to assess mental health. Control variables included sex, age, marital status, education level, occupation status, smoking status, physical activity, and job stress. Multilevel logistic regression analysis was conducted to explore whether individual- and workplace-level social capital was associated with mental health status.
In total, 34.9% of workers reported poor mental health (WHO-5<13). After controlling for individual-level socio-demographic and lifestyle variables, compared to workers with the highest quartile of personal social capital, workers with the third, second, and lowest quartiles exhibited 1.39 to 3.54 times greater odds of poor mental health, 1.39 (95% CI: 1.10–1.75), 1.85 (95% CI: 1.38–2.46) and 3.54 (95% CI: 2.73–4.59), respectively. Corresponding odds ratios for workplace-level social capital were 0.95 (95% CI: 0.61–1.49), 1.14 (95% CI: 0.72–1.81) and 1.63 (95% CI: 1.05–2.53) for the third, second, and lowest quartiles, respectively.
Higher workplace social capital is associated with lower odds of poor mental health among Chinese employees. Promoting social capital at the workplace may contribute to enhancing employees’ mental health in China.

4.  Historical Change in the Link between Adolescent Deviance Proneness and Marijuana Use, 1979–2004 
We examined historical change in the association between adolescent deviance proneness and marijuana use using 26 years (from 1979 through 2004) of national 12th grade data from the Monitoring the Future (MTF) study. “Deviance proneness” was measured using a latent factor model of behavioral and personality characteristics that underlie both substance use and antisocial disorders. Marijuana use outcomes were measured in terms of youths’ annual frequency of use, and youths’ degree of involvement with marijuana. Separate within-gender structural equation models were used to determine whether links between deviance proneness and marijuana use were consistently significant and invariant in magnitude across 13 2-year historical cohorts. Overall results affirmed the established association between adolescent deviance proneness and both the frequency of marijuana use as well as regular use. Among male youth, the size of the association between deviance proneness and marijuana use was significantly smaller at the cohort of lowest population prevalence (1991/92) compared to cohorts marking peaks in marijuana use prevalence, thus suggesting a “softening” historical trend. By contrast, the prediction of female marijuana use from deviance proneness was not consistently related to historical shifts in population prevalence of marijuana use. Study findings point to the utility of risk-focused prevention programming that targets early precursors of both antisocial and substance use disorders.

5.  Investigating Ethnic Differences in Adolescent Alcohol Use and Peer Norms Using Semi-Continuous Latent Growth Models 
Aims: To investigate whether ethnic differences in vulnerability to peer norms supportive of alcohol use is a viable, partial explanation for the ethnic differences in reported prevalence and amount of alcohol use during high school. Methods: Survey data from a sample of 680 adolescents from Project STAR (Students Taught Awareness and Resistance) of the Midwestern Prevention Project were used. Hypotheses were tested using sequential, semi-continuous growth curve models. Results: Relative to Black adolescents, White adolescents reported greater peer alcohol use during middle school and were much more likely to consume alcohol during high school. General peer norms in seventh grade and middle school growth in alcohol use norms among close friends was predictive of a greater propensity to consume alcohol in ninth grade among White adolescents. Conclusion: Lower peer norms for alcohol use among Black adolescents might better account for differences between Black and White adolescents than the possibility that White adolescents are more vulnerable to peer norms.

6.  Family and Neighborhood Fit or Misfit and the Adaptation of Mexican Americans 
In this study, a person-environment fit model was used to understand the independent and combined roles of family and neighborhood characteristics on the adjustment of adults and children in a sample of 750 Mexican American families. Latent class analysis was used to identify six qualitatively distinct family types and three quantitatively distinct neighborhood types using socioeconomic and cultural indicators at each level. The results showed that members of single-parent Mexican American families may be particularly at-risk, members of the lowest-income immigrant families reported fewer adaptation problems if they lived in low-income neighborhoods dominated by immigrants, members of economically successful immigrant families may be more at-risk in integrated middle class neighborhoods than in low-income neighborhoods dominated by immigrants, and members of two-parent immigrant families appear to be rather resilient in most settings despite their low socioeconomic status.

7.  A Person-centered Approach to Studying the Linkages among Parent–Child Differences in Cultural Orientation, Supportive Parenting, and Adolescent Depressive Symptoms in Chinese American Families 
This longitudinal study examined whether supportive parenting mediates relations between parent– child differences in cultural orientation (generational dissonance) and depressive symptoms with a sample of 451 first and second generation Chinese American parents and adolescents (12–15 years old at time 1). Using a person-centered approach, meaningful typologies of cultural orientation were derived for fathers, mothers, and adolescents. Overall, results provided support, though qualified, for the notion that generational dissonance is linked to depressive symptoms through decreased supportive parenting. In general, having a parent with a bicultural profile seemed to be most advantageous if adolescents similarly had a bicultural profile, whereas more American oriented adolescents with more Chinese oriented parents reported the least supportive parenting and most depressive symptoms. Directions for future research and the benefits of using a person-centered approach in research of acculturation and generational dissonance are discussed.

8.  Cultural and Contextual Influences on Parenting in Mexican American Families 
Family stress theory can explain associations between contextual stressors and parenting. However, the theory has not been tested among Mexican Americans or expanded to include cultural-contextual risks. This study examined associations between neighborhood, economic, and acculturative stressors and parenting behaviors in a sample of 570 two-parent Mexican American families. Results support the negative impact of economic stress on parenting through parental depressive symptoms. Neighborhood stress influenced fathers’ depressive symptoms and parenting, but not mothers’. The effects of acculturative stress were inconsistent. Results suggest that contextual stressors common to Mexican American families impact parenting behaviors through parental depression.
