The crossover effect: A review of racial/ethnic variations in risk for substance use and substance use disorder across development

Purpose of Review: The "crossover" effect, a phenomenon by which some minority groups switch from low to high risk for substance use as a function of age, was first documented 25 years ago. However, rigorous methodological research examining the crossover effect has only recently emerged. The current paper reviews the past 25 years of research on the crossover effect, which has primarily examined the shift from low to high substance use risk among Blacks relative to Whites. Recent Findings: Although findings regarding the crossover effect vary based on gender, socioeconomic status, and substance, Blacks and Hispanics appear to be at lower risk for some substance use- particularly binge drinking and cigarette smoking-than Whites during adolescence and early adulthood, but at higher risk for use in later life. Research regarding the crossover effect of substance use disorder and related problems is limited but more consistent with a similar pattern of effects observed. Summary: Due to significant limitations of the extant literature examining the crossover effect, it requires additional research clarifying sociodemographic differences in the, identifying its mechanisms, and determining its clinical implications. Such research may have important implications for preventing racial/ethnic disparities in the consequences associated with disordered substance use

Collective ethnic-racial identity and health outcomes among African American youth: Examination of promotive and protective effects

OBJECTIVES: Racial discrimination is associated with numerous negative health outcomes, including increased risk for depression and anxiety symptoms and substance use. Positive affect toward of one's ethnic or racial group (i.e., ethnic-racial identity affirmation) has been shown to buffer the negative effects of racial discrimination on health outcomes. The extent to which one believes his or her group is valued by others (i.e., positive collective ethnic-racial identity) has also been proposed to be protective. However, to date a limited body of research has examined the moderating effect of collective ethnic-racial identity on health, and among available studies, findings are mixed. METHOD: African American youth (N = 612; 58.2% female, M grade = 8) completed measures on experiences of discrimination, mood symptoms, substance use, ethnic-racial identity affirmation, and collective ethnic-racial identity (assessed using the Collective Self-Esteem Scale). RESULTS: Controlling for demographic variables and affirmation, a significant main effect was found for collective ethnic-racial identity, such that believing that others viewed your group positively was associated with better health outcomes among African American youth. However, collective ethnic-racial identity was not found to buffer the effects of discrimination on health outcomes. CONCLUSIONS: These findings highlight the importance of examining collective ethnic-racial identity and the promotive effect it can have on health outcomes for African Americans. More research is needed to better understand if there are health outcomes in which collective ethnic-racial identity may also mitigate risk as a consequence of racial discrimination.

A longitudinal test of impulsivity and depression pathways to early binge eating onset

OBJECTIVE: The very early engagement in bulimic behaviors, such as binge eating, may be influenced by factors that dispose individuals to impulsive action as well as by factors that dispose individuals to depressive symptomatology. Using a longitudinal design, we conducted the first test of the simultaneous operation of both risk factors as children transition from elementary to middle school. METHOD: In a sample of 1,906 children, we assessed risk for impulsive action (negative urgency, which is the tendency to act rashly when distressed, and eating expectancies, which are learned anticipations that eating will alleviate negative mood) and risk for depression (negative affect and depressive symptomatology) and binge eating behavior at three time points using a longitudinal design: the end of fifth grade (last year of elementary school: T0), the beginning of sixth grade (first year of middle school: T1), and the end of sixth grade (T2). RESULTS: Both the impulsive action and depression pathways predicted very early engagement in binge eating: each accounted for variance beyond the other. Mediation tests found that T1 eating expectancies mediated the predictive influence of T0 negative urgency on T2 binge eating (z = 2.45, p < .01) and that T1 depressive symptoms mediated the influence of T0 negative affect on T2 binge eating (z = 2.04, p < .05). DISCUSSION: In children, elevated levels of both negative urgency and negative affect predict early binge eating. This finding has important clinical implications because there are different interventions for the two different risk processes

Racial Differences in the Transactional Relationship Between Depression and Alcohol Use From Elementary School to Middle School

Objective: The aim of this investigation was to test hypothesized reverse prospective relationships between alcohol consumption and depressive symptomatology as a function of race among youth. Method: In a two-wave prospective study, 328 European American, 328 African American, and 144 Hispanic American youth were studied at the end of fifth grade (last year of elementary school) and the end of sixth grade (first year of middle school). Results: A positive correlation was observed between alcohol consumption and depressive symptoms among all youth. However, the predictive relationship differed based on race. For European American and Hispanic American youth, depressive symptom levels at the end of elementary school predicted alcohol consumption at the end of the first year of middle school, but the converse relationship was not observed. For African American youth, the opposite pattern was found. Alcohol consumption at the end of elementary school predicted depressive symptom levels at the end of the first year of middle school, and the converse relationship was not observed. Conclusions: These findings suggest the possibility that etiological relationships between depression and alcohol use vary by race, thus highlighting the importance of considering race when studying the risk process

Perceived Police Injustice, Moral Disengagement, and Aggression Among Juvenile Offenders: Utilizing the General Strain Theory Model

Although many juvenile offenders report experiencing police injustice, few studies have examined how this source of strain may impact youths' behavioral outcomes, including risk for future recidivism. This study begins to address that gap in the literature. We applied the general strain theory as our theoretical framework to examine the interactive effect of perceived police injustice and moral disengagement on juvenile aggressive behavior. Our sample included 95 juvenile offenders who completed questionnaires on measures of perceived police injustice and moral disengagement. Results supported our hypothesis, such that moral disengagement predicted past month aggression among juvenile offenders, but only by youth who reported mean and high levels of perceived police injustice. While more research is needed in this area, this study's findings underscore the need to address both perceived police engagement and moral disengagement among youth at-risk of engaging in delinquent behaviors. Implications for intervention programs are also presented

The relationship between racial discrimination and substance use: Does locus of control help explain risk?

Introduction Exposure to racial discrimination has been consistently linked with risk for substance use. However, outside of externalizing and affect-based factors, few other mechanisms have been examined. One potential candidate is locus of control, a learning processes that involves the degree to which one attributes rewards as resulting from their own control (internal locus of control) versus outside control (external locus of control). There is evidence that exposure to stressors is associated with locus of control, with a separate body of literature linking locus of control with substance use. Thus, it is plausible that locus of control may be a mechanism underlying the relationship between racial discrimination and substance use. Methods The current study investigated this pathway among 503 racial/ethnic minority adults aged 18&ndash;35 who completed an online questionnaire including measures on racial discrimination related stress, locus of control, and substance use. Results Results indicated a significant indirect effect between racial discrimination related stress, two external domains of locus of control (i.e., powerful others and chance), and substance use. A significant indirect effect was not found for internal locus of control. Conclusion These findings expand our understanding on potential mechanisms that underlie the racial discrimination-substance use risk pathway among racial/ethnic minority adults, which may in turn provide important targets for substance use intervention programming. &nbsp;</p

Differential typologies of current substance use among Black and White high-school adolescents: A latent class analysis

Black and White adolescents demonstrate different prototypical profiles (i.e., typologies) of substance use, with Blacks demonstrating lower risk for concurrent use of two or more substances. Despite knowledge of these differences, typologies of adolescent substance use identified by person-centered methods, such as latent class analysis, have not characterized profiles by racial group. The current study examined typologies of substance use among Black and White youth separately using person-centered methods to identify common patterns of substance use among subjects. Data were drawn from a 5-year parent study examining adolescent health outcomes. The current study examined high-school aged White (n = 7271, 45.4% male) and Black youth (n = 1301, 40.1% male) who reported past-30-day frequency of cigarette, alcohol, marijuana, inhalant, and other drug use. Latent class analysis was used to examine substance use typologies among each group adjusting for grade and sex. Black and White youth demonstrated different typologies such that four typologies emerged among Blacks: Non-Use (87.8%), Alcohol and Marijuana Use (6.3%), Alcohol, Marijuana, and Cigarette Use (3.8%), and Frequent Polysubstance Use (2.0%). Conversely, five typologies emerged among Whites: Non-Use (73.4%), Predominant Alcohol Use (13.9%), Alcohol, Marijuana, and Cigarette Use (9.4%), Moderate Polysubstance Use (1.6%), and Frequent Polysubstance Use (1.7%). Findings suggest that Black and White youth engage in similar rates of concurrent substance use. Given that Black youth face greater risk for adverse consequences from substance use, prevention efforts are needed to prevent related health disparities related to concurrent substance use

Cultural socialization and alcohol use: The mediating role of alcohol expectancies among racial/ethnic minority youth

Introduction: Cultural socialization is associated with reduced risk for several health outcomes among racial/ethnic minority youth. However, to date, less is known about its effect on substance use or the mechanisms through which this process may operate. The current study aimed to examine the effect of cultural socialization on alcohol use through alcohol expectancies among racial/ethnic minority youth. Methods: 113 minority adolescents (69.9% African American; 13.3% Hispanic; 10.6% Multiracial; 2.7% American Indian/Alaskan Native) between ages 12 and 18 (mean age 15) were recruited from community-based after school centers. Participants completed measures on cultural socialization, four alcohol expectancy domains (i.e., positive social, wild and crazy, negative arousal, and sedation), and past year alcohol use. Results: A significant indirect pathway between cultural socialization, alcohol expectancies and alcohol use was found for negative arousal expectancies (b = −0.160, Boot CI [95] = −0.413, −0.021). Indirect paths were non-significant for the other three alcohol expectancies. Conclusions: Our findings suggest that cultural socialization can help reduce alcohol use among racial/ethnic minority adolescents, in part though influencing negative arousal expectancies. Given evidence that alcohol expectancies play an important and long-lasting role in alcohol use across development, incorporating cultural socialization into intervention programming for racial/ethnic minority youth may prove beneficial to reduce risk for alcohol use.

Examination of the indirect effect of alcohol expectancies on ethnic identity and adolescent drinking outcomes

Although overall rates of alcohol use tend to be lower among racial/ethnic minority youth compared to White youth, consequences associated with use tend to be more severe. Identifying factors that prevent alcohol use is crucial to reducing its impact among minority adolescents. One such factor is ethnic identity, which involves gaining clarity about one's ethnic background and regard toward one's ethnic group. Strong ethnic identity has been found to work through antidrug beliefs to decrease minority youth's substance use. The current study extends previous literature by examining whether specific alcohol cognitions-alcohol expectancies-explain the promotive effect of ethnic identity on alcohol use and severity of alcohol use among minority youth. Participants were 113 ethnic minority youth ages 12-18 (M = 15.27). Most participants were male (66%) and identified as non-Hispanic African American/Black (70%), followed by Hispanic/Latino (15%), multiracial (12%), and American Indian/Native American (3%). Participants completed self-report measures of ethnic identity, positive and negative alcohol expectancies, and hazardous drinking, which were analyzed in an indirect effects model. Results indicated that ethnic identity was inversely related to negative alcohol expectancies. A significant indirect effect of ethnic identity on severity of alcohol use through negative alcohol expectancies was found. However, no indirect effect was found for positive alcohol expectancies. Findings suggest that strong ethnic identity serves as a promotive factor preventing alcohol use for ethnic minority youth, in part through more negative alcohol expectancies, and may be a beneficial target for intervention programs to reduce alcohol use among this group.
