The current study examined the longitudinal relations of socio-cultural stressors
(i.e., acculturative stressors, enculturative stressors, ethnic discrimination) and
Mexican-origin adolescent mothers’ depressive symptoms and risk-taking behaviors.
Utilizing an idiographic and nomothetic approach, we conducted lagged analyses to examine
how individuals’ fluctuations in stressors predicted subsequent adjustment.
Further, we investigated potential threshold effects by examining if the
impact of fluctuations in stressors differed at varying levels of stressors.
Mexican-origin adolescent females (N = 184) participated in
yearly in-home assessments across 5 years and reported on their experiences of
acculturative and enculturative stressors, ethnic discrimination, depressive symptoms, and
risk-taking behaviors. Findings revealed that within-person fluctuations in acculturative
stressors, and to a lesser extent, perceived discrimination, related to youths’
depressive symptoms. For risk-taking behaviors, however, only within-person fluctuations
in enculturative stressors emerged as significant. Further, a threshold effect emerged in
the link between enculturative stressors and risk-taking behaviors, suggesting that
fluctuations in enculturative stressors predicted changes in risk-taking behaviors at high
levels of enculturative stressors, but not low levels. Our findings highlight the
differential relations between socio-cultural stressors and adolescent females’
adjustment, and suggest that prevention programs aimed at reducing depressive symptoms
should attend to any degree of change in socio-cultural stressors,
whereas programs focused on risk-taking behaviors should be especially attuned to levels
of enculturative stress.
