    Adverse childhood experiences, executive function, and maladaptive behaviors in children involved with child protective services
    (Colorado State University. Libraries, 2024) Carvalho, Isidro, author; Daunhauer, Lisa, advisor; Aichele, Stephen, committee member; Sample, Pat, committee member; Barrett, Karen, committee member; Riggs, Nathaniel, committee member
    Childhood traumatic events are common and frequently associated with maladaptive coping mechanisms which contribute to long-term harm. Yet few targeted treatment options exist to prevent maladaptive coping in children exposed to trauma. The purpose of this thesis is to identify if executive function may serve as a potential target for such interventions. This thesis used a sample of 244 children – aged 6 to 18 years old – who were referred by the Larimer County Department of Human Services for trauma assessments. Participant trauma events, executive function, and maladaptive behavior data were used to determine if executive function moderated the established association between trauma events and maladaptive behavior development. Results showed no significant interaction between trauma events and executive function when assessing for either maladaptive internalization or externalization. However, results indicated that executive function had a main effect on both internalization and externalization. This study emphasizes the need for further research on the associations between childhood trauma, executive function, and maladaptive behaviors. It is imperative that moderators of the association between childhood trauma and maladaptive behaviors are found so that new treatment options can be developed.

    Age group differences in responses to laboratory stressors: task appraisals and affect reactivity
    (Colorado State University. Libraries, 2022) Miller, James Walter, author; Luong, Gloria, advisor; Aichele, Stephen, committee member; Graham, Daniel, committee member
    Several theories of lifespan socioemotional development posit that adults become more adept at regulating their emotions during stressful situations as they age. However, mixed findings in the literature do not yet provide clear support for this assumption. Cognitive appraisals have been found to influence affective reactivity to stressors, but few studies have directly examined their role in explaining age-group differences in affective reactivity. Additionally, there is limited information available for how trajectories of adaptation in affective reactivity and cognitive appraisals in response to equivalent stressor exposures may vary across adult age-groups. To address these gaps in the literature, the current study used a structural equation modeling framework to examine younger (n = 138) and older adults' (n = 106) trajectories of affective reactivity and cognitive appraisals in response to three exposures to the Trier Social Stress Test. We then investigated the extent to which, over time, changes in cognitive appraisals accounted for age-group differences in changes of affective reactivity. Older adults reported attenuated reductions in negative affective reactivity, smaller decreases in appraisals of task-difficulty, and reduced improvements in appraisals of task-performance, relative to younger adults. Additionally, older adults' appraisals of the task as relatively more difficult over time accounted for their comparatively elevated levels of negative affective reactivity across assessments. Together, these findings suggest that older adults, compared to younger adults, may show attenuated trajectories of adaptation to repeated stressor exposures when the stressor is novel, uncontrollable, or especially threatening to older adults.

    Trajectories of acculturation, enculturation, and depressive symptoms: findings from a longitudinal study of Latinx adolescents in Los Angeles
    (Colorado State University. Libraries, 2024) Ramirez, Carla M., author; Riggs, Nathaniel, advisor; Aichele, Stephen, committee member; Most, David, committee member; Rieker, Julie, committee member
    Acculturation is conceptualized as a dynamic process of change over time within individuals, yet the bulk of the research on acculturation is conducted using cross-sectional, as opposed to longitudinal approaches. Although there is an emerging body of longitudinal work in this area, there are several factors that contribute to within and between-person variation in acculturation that have yet to be explored. Furthermore, research examining the extent to which change over time in acculturation is related to the rate of change in depressive symptoms is scant. This dissertation utilized a longitudinal data set examining acculturation and substance use among a sample of Latinx youth in Los Angeles, California. Survey data assessing cultural processes, stressors, and depressive symptoms was collected in-person and electronically between 2005 and 2018. Study 1 used growth curve modeling to examine the extent to which there was developmental change in acculturation during the period of adolescence and into early adulthood. The results revealed that there was significant change over time in acculturation and that to some extent change over time varied by the generational group. Study 2 examined how change over time in cultural processes (e.g., acculturation, enculturation, and ethnic identity) was related to changes in depressive symptoms and the extent to which these cultural processes moderated the relationship between stressors and depressive symptoms. The results of study 2 elucidated the moderating effects of the rate of change in acculturation on the association between the rate of change in perceived discrimination and the rate of change in depressive symptoms. This study provides new insights for acculturation research regarding change over time in this construct and the importance of considering context when examining the effect of acculturation on depressive symptoms. Furthermore, the combined results of these studies have important implications for the interpretation of previous studies using proxy measures of acculturation that are discussed further in text. Recommendations for improving the mental health and well-being of Latinx youth are also discussed.
