  1. Stress Response and Adolescents’ Adjustment: The impact of child maltreatment Emily C. Cook Rhode Island College Tara M. Chaplin, Rajita Sinha, Jacob K. Tebes, & Linda C. Mayes Yale University 14th Biennial Meeting of the Society for Research on Adolescence, Vancouver, BC

  2. Background • Adolescence is a critical time to examine the relationship between stress response and adjustment. • Heightened reactivity to a stressor has been associated with both adaptive and maladaptive functioning. • Variability in findings may be explained by context. • Child maltreatment may be one important context that explains variability in findings.

  3. Study Aims • To examine the effect of adolescents’ stress response on anger regulation and interpersonal competence. • To examine child maltreatment as a moderator of the relationship between adolescents’ stress response and anger regulation and interpersonal competence.

  4. Proposed Relationship: The Impact of Child Maltreatment on the Relationship between Adolescents’ Stress Response and Adjustment Negative Adjustment

  5. Methods: Sample • Utilized data from a longitudinal project of low income urban families followed since birth • Sub-Sample • Adolescents recruited if no acute psychiatric conditions, no serious medical conditions, not pregnant, and IQ > 80 • N =175 adolescents; 51.8% girls • Youth 14 ½ to 16 years of age ( M = 15.36, SD = 1.01) • 86.9% African American

  6. Methods: Procedures • 4 sessions spaced 1 week apart • Session 1 and 2 : completed questionnaires • Session 3 : laboratory- based stress session (TSST-C)

  7. Methods: Measures • Adolescents’ Stress Response (peak – baseline) • Salivary cortisol levels • Blood pressure • Heart rate • Adolescents’ Adjustment • Anger Regulation (BASC-SRP) • Interpersonal Competence (BASC-SRP) • Child Maltreatment (CTQ short form)

  8. Analytic Plan • Structural Equation Modeling (AMOS 18.0) • Stress responses examined in separate analyses • Path models • Multiple group models • Analyses controlled for gender

  12. Summary of Results Findings from sample as a whole suggested heightened reactivity was associated with adolescents’ adjustment. Found differences for youth low and high in child maltreatment such that: Heightened reactivity associated with positive functioning for youth low in child maltreatment. Heightened reactivity associated with negative functioning for youth high in child maltreatment .

  13. Discussion • Heightened reactivity appears to be associated with positive functioning but associations were modest. • Heightened stress reactivity may be adaptive for youth who report low levels of maltreatment but not high levels, a finding consistent with Boyce’s and Ellis’ theory. • For youth high in child maltreatment, heightened stress reactivity was associated with anger regulation problems, problems that are markers for externalizing behavior.

  14. Limitations and Future Directions • Need to conduct longitudinal studies • Need to assess supportive aspects of environment not just adverse aspects • Important to examine different patterns and trajectories of stress response and the relationship to context and adolescent outcomes
