Temporal Orientation and the Association Between Adverse Life Events and Internalizing Symptoms in Vietnamese American and European American Adolescents.

Adverse life events are associated with greater internalizing symptoms. However, prior research has identified cross-cultural variation in whether and to what extent factors amplify or buffer the impact of these stressors. Broadly defined as the tendency to focus on past, present, or future events, temporal orientation is a dispositional factor that is culturally influenced and may explain variance in internalizing symptoms following adverse events. Cultural congruence, or the degree to which a factor is considered normative in an individual's culture, may be an important explanation of variation in levels of risk. The current study examines how culturally congruent temporal orientation differentially impacts the relation between adverse life events and internalizing symptoms in a longitudinal sample of 10th and 11th grade Vietnamese American (n = 372) and European American adolescents (n = 304). Results indicated that Vietnamese American adolescents endorsed significantly higher levels of past and present, but not future, temporal orientation compared to European American adolescents. Among both Vietnamese and European American adolescents, past temporal orientation was positively associated with internalizing symptoms and adverse life events. Findings also demonstrated that the influence of present temporal orientation on the relation between adverse life events and internalizing symptoms was further moderated by ethnicity, such that present temporal orientation buffered risk for negative outcomes among European Americans but not Vietnamese Americans. These data highlight the importance of measuring and testing specific dimensions of culturally relevant processes when considering responses to adverse life events.

Effects of individual differences, society, and culture on youth-rated problems and strengths in 38 societies.

BACKGROUND: Clinicians increasingly serve youths from societal/cultural backgrounds different from their own. This raises questions about how to interpret what such youths report. Rescorla et al. (2019, European Child & Adolescent Psychiatry, 28, 1107) found that much more variance in 72,493 parents' ratings of their offspring's mental health problems was accounted for by individual differences than by societal or cultural differences. Although parents' reports are essential for clinical assessment of their offspring, they reflect parents' perceptions of the offspring. Consequently, clinical assessment also requires self-reports from the offspring themselves. To test effects of individual differences, society, and culture on youths' self-ratings of their problems and strengths, we analyzed Youth Self-Report (YSR) scores for 39,849 11-17 year olds in 38 societies. METHODS: Indigenous researchers obtained YSR self-ratings from population samples of youths in 38 societies representing 10 culture cluster identified in the Global Leadership and Organizational Behavioral Effectiveness study. Hierarchical linear modeling of scores on 17 problem scales and one strengths scale estimated the percent of variance accounted for by individual differences (including measurement error), society, and culture cluster. ANOVAs tested age and gender effects. RESULTS: Averaged across the 17 problem scales, individual differences accounted for 92.5% of variance, societal differences 6.0%, and cultural differences 1.5%. For strengths, individual differences accounted for 83.4% of variance, societal differences 10.1%, and cultural differences 6.5%. Age and gender had very small effects. CONCLUSIONS: Like parents' ratings, youths' self-ratings of problems were affected much more by individual differences than societal/cultural differences. Most variance in self-rated strengths also reflected individual differences, but societal/cultural effects were larger than for problems, suggesting greater influence of social desirability. The clinical significance of individual differences in youths' self-reports should thus not be minimized by societal/cultural differences, which-while important-can be taken into account with appropriate norms, as can gender and age differences.

Latent profile analyses of disordered eating behaviors and nonsuicidal self-injury among Vietnamese adolescents.

OBJECTIVE: Comorbidity of disordered eating (DE) behaviors and nonsuicidal self-injury (NSSI) is linked to increased functional impairment. The present study identified subtypes of DE and NSSI comorbidity in a non-Western, low- and middle-income country where there has been particularly little research in this area. METHOD: Latent profile analyses (LPA) were conducted to identify patterns of subgroup comorbidity in self-reported DE behaviors and NSSI behaviors, in a sample of Vietnamese high-school students (N = 1451, 51% female). Parallel-process LPA was used to predict NSSI subgroup membership from DE subgroup membership. RESULTS: A seven-class LPA model was identified for DE: (1) Low frequencies of all DE behaviors; (2) Frequent levels of all DE behaviors; (3) Frequent fasting and purging behaviors; (4) Frequent binge eating only; (5) Moderate binge eating; (6) Moderate fasting and purging behaviors; (7) Exercise and fasting. A two-class (high versus low) model was identified for NSSI. Odds of membership in the high-NSSI class were significantly increased for all DE classes except the class characterized by moderate binge eating. Odds of belonging to the high-NSSI class were highest for those in DE classes involving purging behaviors. Males predominated in classes characterized by high behavior dysregulation. DISCUSSION: DE and NSSI represent important clinical concerns among Vietnamese youth in urban contexts, and males may show particular vulnerability for certain risk behaviors. The association of classes of DE behaviors to NSSI was particularly strong for classes that involved purging, highlighting the importance of this specific behavior for understanding comorbidity of DE and NSSI. PUBLIC SIGNIFICANCE: Disordered eating and nonsuicidal self-injury (NSSI; hurting oneself without intending to die) commonly co-occur. There has been less research on disordered eating and NSSI among individuals from non-Western or low/middle-income countries. We examined patterns of these behaviors in a school-based sample of Vietnamese adolescents. We found that patterns of disordered eating distinguished by purging showed particular links to NSSI, which could have implications for screening and treatment.

How discrimination experiences relate to racial/ethnic identity and mental health across first- and second-generation Vietnamese American adolescents.

OBJECTIVES: Racial/ethnic discrimination has been linked to behavioral and emotional problems in youth from marginalized groups. However, the psychological experience associated with discrimination may differ between immigrant and nonimmigrant youth. Race-based discrimination may impact an adolescent's view of their own group (private regard) and/or their sense of how others view their group (public regard). Owing to differences in racialization, immigrant adolescents may be affected differently by experiences of discrimination than their U.S.-born peers. The present study examined whether nativity moderated the paths from racial/ethnic discrimination to private and public regard to mental health problems among Vietnamese American youth. METHOD: Surveys were completed by 718 Vietnamese American 10th and 11th graders (Mage = 15.54 years, 61.4% female, 38.6% male). In this sample, 21.2% were first-generation (i.e., born outside of the United States) and 78.8% were second-generation (i.e., born in the United States with at least one parent born outside of the United States). RESULTS: Multigroup path analysis tested the direct and indirect effects of racial/ethnic discrimination on behavioral and emotional problems via private and public regard and whether associations differed for first- versus second-generation youth. Racial/ethnic discrimination was associated with lower public regard, but not private regard, for both first- and second-generation Vietnamese American youth. Public regard was negatively associated with behavioral and emotional problems only among second-generation youth. No indirect effects were significant. CONCLUSIONS: Findings suggest differences in racialized experiences, as well as opportunities to support second-generation Vietnamese American and other marginalized youth from immigrant families from the mental health impacts of discrimination.

Building global capacity for brain and nervous system disorders research.

The global burden of neurological, neuropsychiatric, substance-use and neurodevelopmental disorders in low- and middle-income countries is worsened, not only by the lack of targeted research funding, but also by the lack of relevant in-country research capacity. Such capacity, from the individual to the national level, is necessary to address the problems within a local context. As for many health issues in these countries, the ability to address this burden requires development of research infrastructure and a trained cadre of clinicians and scientists who can ask the right questions, and conduct, manage, apply and disseminate research for practice and policy. This Review describes some of the evolving issues, knowledge and programmes focused on building research capacity in low- and middle-income countries in general and for brain and nervous system disorders in particular.

Longitudinal Relations between Emotion Restraint Values, Life Stress, and Internalizing Symptoms among Vietnamese American and European American Adolescents.

Objective: Recent research has documented cultural differences in the extent and manner in which various forms of emotion regulation are linked with psychological well-being. Most of these studies, however, have been cross-sectional, nor have they directly examined the values underlying the use of emotion regulation. The present study examined emotion restraint values and their interactions with life stress in predicting internalizing symptoms across time among Vietnamese American and European American adolescents. The study focused on adolescence as a critical developmental period during which life stress and internalizing symptoms increase significantly. Method: Vietnamese American (n = 372) and European American (n = 304) adolescents' levels of emotion restraint values, internalizing symptoms, and stress were assessed at two timepoints six months apart. Results: Results indicated differential associations between emotion restraint values, stress, and symptoms over time for the two groups. For Vietnamese American adolescents, emotion restraint values did not predict depressive, anxiety, or somatic symptoms. For European American adolescents, emotion restraint values predicted higher somatic symptoms but buffered against the effects of interpersonal stress on anxiety and depressive symptoms. Conclusions: These results provide increased understanding of the role of values related to emotion restraint in shaping adolescent internalizing symptoms and responses to stress across cultural groups. Implications of the findings for guiding intervention efforts are discussed.

Interpersonal Psychotherapy-Adolescent Skills Training With Youth From Asian American and Immigrant Families: Cultural Considerations and Intervention Process.

Although research has identified effective evidence-based depression prevention interventions for diverse youth, little is known about how the intervention process unfolds with immigrant family youth. This study utilized a qualitative approach to explore cultural and clinical differences in the implementation of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST) in two schools, one serving youth from primarily immigrant, Asian American families and the second, youth from mostly nonimmigrant, non-Hispanic White families. A total of 131 IPT-AST sessions were audio recorded, transcribed, and coded for presence and patterns of cultural and clinical constructs. Results revealed that sessions with immigrant family youth were more likely to contain discussions of interpersonal problems characterized by estrangement, goals of spending time together with important others, mentions of emotion suppression and academic achievement expectations, conversations about acculturation, differences in value orientation, and discomfort with implementing new intervention skills. Dialogue from interventionist and youth exchanges is presented to illustrate how these themes emerged and were addressed by interventionists in a culturally responsive manner. The study highlights how IPT-AST with immigrant family and Asian American youth may unfold differently compared to youth from nonimmigrant families. Implications of findings for providers are discussed.

Adolescents' family obligation and activities in rural and urban Vietnam: Implications for social change.

This study examined how urbanisation may modify adolescents' values and activities concerning family obligation by surveying 572 adolescents (Mage  = 15.75, SD = .73) in rural and urban Vietnam. Compared with their rural peers, urban adolescents reported a stronger sense of family obligation but spent less time actually engaging in family assistance, findings that were partly explained by urban households' less financial hardship and higher parental education levels. As expected, stronger family obligation values were associated with greater family assistance activities across rural and urban Vietnam. However, stronger family obligation values were associated with more study hours only in urban Vietnam, indicating that urbanisation may broaden the meaning of family obligation to encompass the academic domain. Additionally, weaker family obligation values were associated with more employment hours only in rural Vietnam, suggesting that rural adolescents with little attachment to the traditional value of family obligation may pursue autonomy through employment outside the home. In traditionally familistic societies undergoing urbanisation, family obligation may take on different meaning depending on adolescents' ecological settings that construct cultural values and behavioural norms.

Urbanization, and child mental health and life functioning in Vietnam: implications for global health disparities.

PURPOSE: Urbanization is linked to increased health risks, including mental health. However, the large majority of this research has been conducted in high-income countries, and little is known about effects in low-and-middle-income countries (LMIC) where urbanization is occurring most frequently and most rapidly. Within global mental health, children and adolescents are a critical but understudied population. The present study assessed relations between urbanization factors, and child mental health in Vietnam, a Southeast Asian LMIC. METHODS: Most studies investigating urbanization and mental health have used geographically based dichotomous urban vs. rural variables. Because of significant limitations with this approach, the present study assessed parent-reported urbanization factors (e.g., pollution, crime). In Sub-study #1 (cross-sectional), 1314 parents from 10 Vietnam provinces completed the Urbanization Factors Questionnaire, Child Behavior Checklist (mental health), and Brief Impairment Scale (life functioning). In Sub-study #2 (longitudinal), 256 parents from one highly urban and one highly rural province completed the same measures, at three timepoints across 12 months. RESULTS: Cross-sectional canonical correlations identified relatively small (e.g., R2 = 0.08) but significant relations between urbanization factors, and child functioning. Parallel analyses using a geographically defined urban vs. rural variable did not produce significant results. The large majority of longitudinal relations between the different urbanization factors and child functioning were non-significant. CONCLUSIONS: This study, among the first to assess urbanization as a multi-dimensional continuous construct in relation to child psychopathology, highlights the value of the use of an urbanization factors approach. A new "urbanization factors differentials" theory is proposed to suggest how effects of urbanization factors might result in global health disparities.

Explanatory variables for women's increased risk for mental health problems in Vietnam.

PURPOSE: The United Nations Sustainable Development Goals include gender equality for women, including health, as one of seventeen targets. Within this broad domain, a wide range of research indicates that being female is associated with increased risk for mental health problems, particularly in low- and middle-income countries (LMIC). What is less clear are the trans-diagnostic demographic and environmental risk factors in LMIC that may underlie this increased risk. The purpose of the present study was to identify socio-economic and related disadvantages potentially underlying increased risk for women for mental health-related problems in the Southeast Asian LMIC of Vietnam. METHODS: Nine hundred and seventy-seven adults were randomly selected from five provinces in central coastal Vietnam. Individuals were assessed cross-sectionally for depression (PHQ-9), anxiety (GAD-7), post-traumatic stress disorder symptoms (PDS), somatic syndrome (SCL-90-R), alcohol dependence (ICD-10), functional impairment (PDS life functioning section), and self-perceived general physical health (SF-36). Trans-diagnostic risk factors assessed included financial stress, education level, exposure to traumatic events, and others. RESULTS: At the multivariate level, gender explained approximately 5% of the variance in mental health symptoms, with women significantly higher in all mental health domains except alcohol dependency. The trans-diagnostic risk factors explained slightly over half of this variance, with financial stress and lower education levels the two strongest individual explanatory variables for women's increased risk for mental health problems. CONCLUSIONS: These results suggest that support for gender equality including in regard to economic stability and education may be critical for reducing broad gender disparities in mental health functioning.

Effects of Preference on Outcomes of Preventive Interventions among Ethnically Diverse Adolescents At-Risk of Depression.

Patient-centered care includes efforts to align treatment with patient preferences to improve outcomes and has not been studied in adolescent depression prevention. Within a school-based randomized trial, we examined the effects of offering a preference between two evidence-based preventive interventions for youth at risk of depression, Learning to BREATHE (L2B) and Interpersonal Therapy-Adolescent Skills Training. We examined the effects of 3 preference factors (assignment condition [preference vs. random], receipt of preferred program, and baseline program preference) on outcomes in a diverse sample of 111 adolescents (M age = 15.18 years, SD = .86): 81 (73%) girls, 45 (41%) White, 40 (36%) Asian American, 8 (7%) Latinx, 1 (1%) African American, and 17 (15%) multiracial or other race/ethnicity. Findings revealed little evidence that receiving a preferred intervention or being given a choice of interventions was linked to greater improvement or initial engagement. Further, analyses did not indicate that adolescents with baseline indications for a specific intervention would benefit more from that intervention; rather, adolescents with generally lower baseline functioning improved more regardless of the intervention received. However, receipt of L2B and a baseline preference for L2B were associated with greater improvements in about half of the outcomes examined, with effect sizes ranging from R 2 = 0.04 to 0.14. There was little support for the need to match interventions to adolescent preferences in school-based prevention efforts. Rather, the more scalable mindfulness-based intervention had stronger effects than the interpersonal intervention and may hold promise for diverse adolescents.

Prospective relations between parent-adolescent acculturation conflict and mental health symptoms among Vietnamese American adolescents.

OBJECTIVES: Intergenerational acculturation conflict in immigrant families has been implicated as a risk factor for adolescent maladjustment. However, the directionality and specific family related mediators of this association have not been identified. The present study prospectively examined relations between adolescent reports of perceived acculturation conflict and internalizing and externalizing mental health symptoms. Perceived parent-adolescent relationship strain and perceived parental psychological control were examined as potential mediators. METHOD: Survey measures were administered to 375 Vietnamese American adolescents (48.8% males; M = 15.55 years, SD = .59) at 3 time points over 6 months. RESULTS: Using cross-lagged path analysis, perceived acculturation conflict predicted externalizing symptoms, whereas internalizing symptoms predicted perceived acculturation conflict. Perceived maternal psychological control mediated the association between perceived acculturation conflict and later externalizing symptoms, whereas maternal psychological control, parental unresponsiveness, and unmet parent expectations mediated the association between internalizing symptoms and later acculturation conflict. CONCLUSION: Culturally competent enhancement of parental sensitivity and responsiveness might be targeted as a modifiable protective factor in family-based preventive interventions for at-risk immigrant families.

Vietnam as a case example of school-based mental health services in low and middle income countries: Efficacy and effects of risk status.

The purposes of this study were to (a) assess the efficacy of a universal classroom-based mental health and social skills program for primary school students in Vietnam, and (b) given the universal nature of the intervention, assess outcomes as a function of risk status (high vs. low). RECAP-VN is a semi-structured program that provides students with classroom social skills training, and teachers with in-classroom consultation on program implementation and classroom-wide behavior management. Project data were collected at three time-points across the academic year from 443 2nd grade students in regards to their social skills and mental health functioning, in the Vietnamese cities of Hanoi and Danang. Mental health functioning (emotional and behavioral mental health problems) was the ultimate outcome target (at Time 3), with social skills intermediate (at Time 2) outcomes targeted to improve mental health functioning. Significant treatment effects were found on both social skills and mental health functioning. However, although program effects on mental health functioning were significant for both low and high risk status groups, program effects on social skills were only significant for low risk status students, suggesting that different mechanisms may underlie program effects for high and low risk status students. Overall the results of this study, one of the first to assess directly the effects of a school-based program on mental health functioning in a low or middle income country, provide some support for the value of using school-based programs to address the substantial child mental health treatment gap found in low- and middle-income countries.

Functional impairment and mental health functioning among Vietnamese children.

PURPOSE: Functional impairment is a key indicator of need for mental health services among children and adolescents, often a stronger predictor of service usage than mental health symptoms themselves. Functional impairment may be of particular importance in low- and middle-income countries (LMIC) because of its potential to focus policy on treatment of child mental health problems which is generally given low priority in LMIC. However, few studies have assessed functional impairment in LMIC. The present study assessed rates of functional impairment among children in Vietnam, as a case example of an LMIC, as well as effects of other risk/protective factors of particular relevance to LMIC (e.g., whether the family lived in an urban or rural area; family structure variables such as grandparents living with the family). METHODS: 1314 parents of children 6-16 years old from 10 Vietnamese provinces were interviewed. RESULTS: The overall rate of functional impairment among Vietnamese children was 20 %, similar to rates in high-income countries such as Germany and the United States, suggesting that LMIC status may not be associated with dramatic increases in functional impairment in children. Functional impairment was significantly greater among mental health cases than non-cases, with increases of over 550 % associated with mental health caseness. A number of other risk factors (e.g., marital status) had smaller but significant effects. CONCLUSIONS: Mental health problems are a major but not the sole contributor to functional impairment among Vietnamese children. The pragmatic significance of this research lies in its potential to affect public awareness and policy related to child mental health in LMIC.

Linkages between mental health need and help-seeking behavior among adolescents: Moderating role of ethnicity and cultural values.

Risk of developing emotional and behavioral mental health problems increases markedly during adolescence. Despite this increasing need, most adolescents, particularly ethnic minority youth, do not seek professional help. Informed by conceptual models of health behavior, the current study examined how cultural values are related to help seeking among adolescents from 2 distinct racial/ethnic groups. Using a prospective survey design, 169 Vietnamese American and European American youth in 10th and 11th grade reported on their mental health need, as measured by emotional/behavioral mental health symptoms and stressful life events, with participants reporting on their help-seeking behavior at 6-month follow-up assessments. Multinomial logistic regression analyses indicated that mental health need interacted with cultural values and ethnicity to predict help-seeking behavior. Specifically, associations between symptoms and stressful life events, and help-seeking behavior were smaller among Vietnamese American adolescents, and among adolescents with strong family obligation values. These results underscore the complex sociocultural factors influencing adolescents' help-seeking behavior, which have important implications for engaging youth in needed mental health care.

Parent-teacher agreement on children's problems in 21 societies.

Parent-teacher cross-informant agreement, although usually modest, may provide important clinical information. Using data for 27,962 children from 21 societies, we asked the following: (a) Do parents report more problems than teachers, and does this vary by society, age, gender, or type of problem? (b) Does parent-teacher agreement vary across different problem scales or across societies? (c) How well do parents and teachers in different societies agree on problem item ratings? (d) How much do parent-teacher dyads in different societies vary in within-dyad agreement on problem items? (e) How well do parents and teachers in 21 societies agree on whether the child's problem level exceeds a deviance threshold? We used five methods to test agreement for Child Behavior Checklist (CBCL) and Teacher's Report Form (TRF) ratings. CBCL scores were higher than TRF scores on most scales, but the informant differences varied in magnitude across the societies studied. Cross-informant correlations for problem scale scores varied moderately across societies studied and were significantly higher for Externalizing than Internalizing problems. Parents and teachers tended to rate the same items as low, medium, or high, but within-dyad item agreement varied widely in every society studied. In all societies studied, both parental noncorroboration of teacher-reported deviance and teacher noncorroboration of parent-reported deviance were common. Our findings underscore the importance of obtaining information from parents and teachers when evaluating and treating children, highlight the need to use multiple methods of quantifying cross-informant agreement, and provide comprehensive baselines for patterns of parent-teacher agreement across 21 societies.

The Vietnam Multicomponent Collaborative Care for Depression Program: Development of Depression Care for Low- and Middle-Income Nations.

In this article, we discuss the Vietnam Multicomponent Collaborative Care for Depression Program, which was designed to provide evidence-based depression care services in low-resource, non-Western settings such as Vietnam. The article provides the program development background; the social, economic, and political context in which the program was developed; and the structure and content of the program and their underlying rationale in the context of rural Vietnam. Although the program was found to be acceptable, feasible, and effective in reducing depression outcomes, we did face challenges in implementation, which are outlined in this article. Key challenges included cultural factors (e.g., a lack of recognition of depression as a health-related entity amenable to professional treatment, relatively low levels of psychological mindedness useful for understanding of psychological interventions) and health system (e.g., lack of mental health specialists, overburdened health providers unfamiliar with behavioral interventions) factors. We discuss the strategies we employed to resolve these challenges and our successes and failures therein. We conclude with recommendations for others interested in implementing similar programs in low- and middle-income countries settings.

Mixed-methods needs assessment for development of school-based mental health implementation science capacity in low- and middle-income countries: Vietnam as a case example.

Worldwide, the majority of youth reside in low- and middle-income countries (LMIC). School-based mental health (SBMH) services are particularly important in LMIC, in part because of LMIC's limited mental health infrastructure. Among the challenges to developing SBMH in LMIC are limited implementation science (IS) capacity, critical for identifying barriers to evidence-based intervention (EBI) use and dissemination, etc., specific to the local country context. A key step in IS capacity development is conducting a needs assessment, to identify barriers (and their solutions) to IS development itself within the local context. The present study conducted an IS needs assessment focused on SBMH in the Southeast Asian LMIC of Vietnam. Seventy-five Vietnamese mental health professionals in SBMH-related fields participated in a mixed-methods study. Vietnamese SBMH researchers and practitioners most likely to have experience and/or interest in IS were selected for study recruitment. Professionals' formal understanding of and experience with IS as a scientific field was highly limited. However, after reading a brief but detailed description of IS, participants' interest in IS training was high, and their mean rating of its potential utility for Vietnam to develop SBMH was 4.7 on a 1-5 scale. Participants also reported on barriers and potential solutions for EBI use in SBMH in Vietnam. Contrary to expectations, the most frequent and severe barriers were not financial but related to limited stakeholder engagement. Overall, these and other study results provide some suggestions how IS capacity to support SBMH may be most efficiently developed in settings such as Vietnam.

Relations between risk perception, perceptions of peers' driving, and risky driving among Cambodian adolescents.

Introduction: Traffic accidents are a leading cause of death globally, with substantial economic impact particularly in low-and-middle-income countries (LMIC). Adolescents are at particular risk, partly due to their tendency to engage in risky driving. However, most research designed to identify potential causes of risky adolescent driving has been conducted in Western, high-income countries, which often have substantial cultural differences from LMIC that potentially influence risky adolescent driving. Methods: The present study, one of the first focused on this topic in Southeast Asia, cross-sectionally assessed 425 adolescent motorbike drivers in the Southeast Asian LMIC Cambodia. Adolescents' (a) beliefs about peers' driving (social norms) and (b) driving risk perception were assessed as predictors of four risky driving behaviors: aggressive driving; distracted driving; intoxicated driving; violating driving laws. Results: Canonical correlation analysis identified a general relation between (a) beliefs about peers' driving, and (b) all four risky driving behaviors, with R2 = 0.35 indicating over one-third of the variance in risky driving was explained by perceptions of peers' driving. Risk perception was not involved in the significant canonical relation, however. Gender moderated two of the underlying relations, with females showing larger relations between perceptions of friends' driving, and distracted driving and violating driving laws. Discussion: These findings provide useful directions for future research (e.g., assessing the accuracy of Cambodian adolescents' perceptions of peers' driving) useful for helping stakeholders tailor road safety programs (e.g., providing adolescent drivers with accurate information regarding their peers' actual driving behaviors) for adolescent motorcyclists in Cambodia and similar countries.

Concurrent and convergent validity of culture-specific psychopathology syndromes among Cambodian adolescents.

Psychopathology is defined in part by its impacts on life functioning (e.g., fulfillment of daily responsibilities at work or school, in family relationships). Relations to life functioning are particularly important in the validation of culture-specific syndromes (patterns of mental health symptoms specific to a particular culture), to demonstrate that culture-specific symptom patterns do in fact represent pathology. The current study's goal was to assess the construct validity of the Cambodian Somatic Symptom and Syndrome Inventory (CSSI). The study focused on the statistically unique effects of the CSSI on life functioning (i.e., effects of the CSSI on life functioning, controlling for Western psychopathology syndromes), to determine whether the CSSI contributes information beyond standard Western measures, which would support CSSI culture-specific convergent validity. Because adolescence is a key period when psychopathology often develops, study participants were 391 high-school students in one urban and one rural area of Cambodia. Participants completed the CSSI, the Western psychopathology surveys Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder questionnaire (GAD-7), and life functioning measures assessing functional impairment, quality of life, and help-seeking. Results indicated strong CSSI concurrent validity (canonical correlation = 0.75) with the PHQ-9 and GAD-7, and CSSI total effects convergent validity on life functioning indicators. All CSSI statistically unique effects (controlling for the PHQ-9 and GAD-7) on life functioning measures were non-significant indicating that the CSSI, shown to be a valid assessment measure in the current study, does not add predictive information beyond standard Western measures. A key limitation that should be considered in interpretation of these results is that the life functioning measures, although reviewed by Khmer psychologists, were Western-based, thus potentially inflating relations with Western psychopathology measures.
