The Effects of Classroom Environmental Quality on the Early Literacy Outcomes of a Regionally Heterogeneous Population of Latino Children

The purpose of this study was to examine the relation between classroom environmental quality and early literacy outcomes amongst a sample of Latino children from various Latin-American countries. Participants included 116 preschoolers that attended various childcare centers in Southeast Florida. Participant’s literacy knowledge was assessed using the Test of Preschool Early Literacy. Classrooms were assessed on environmental quality using the Early Childhood Environmental Rating Scale-Revised. A regression analysis revealed that classroom environmental quality did not account for Latino children’s early literacy outcomes. However, a multiple regression analysis was significant (R2= .15, F(5, 115) = 3.86, p< .05) indicating that quality has a varying impact on children’s early literacy skills based on children’s region of origin. Findings suggest that high classroom environmental quality does not necessarily mean better literacy development for Latino children. Additionally, Latino children should not be viewed as a homogeneous group, particularly in relation to their development of literacy skills in English.

Predicting posttraumatic stress reactions in children prior to traumatic exposure

The present study examined the relations among previously identified risk and protective variables associated with traumatic exposure and evaluated a model of resilience to traumatic events among Latino youth prior to traumatic exposure using structural equation modeling. Model tests were pursued in the context of Full Information Maximum Likelihood (FIML) methods as implemented in Mplus. The model evaluated the role of the following variables: (a) intervening life events; (b) child characteristics; (c) social support from significant others; and (d) children's coping. Data were collected from 181 Latino youth (M age = 9.22, SD = 1.38; 49.0% female) participants. Data analyses revealed that children's perceived available social support and use of coping strategies predicted low state anxiety following exposure to cues of disaster. Life events and preexisting depression symptoms did not significantly predict social support and coping, whereas preexisting anxiety was a significant predictor of perceived social support. This study represents an important initial step towards establishing and empirically evaluating a resilience model. Implications for preparedness interventions and a framework for the etiology of resilient reactions to disaster exposure are discussed.

Anxious children who received treatment grow -up: An 8-to-13 year follow-up study

This dissertation examined the long-term efficacy (8-to-13 years, M = 9.54, SD = 1.689) of exposure-based cognitive-behavioral therapy (CBT) for phobic and anxiety disorders in youths. Long-term efficacy was examined in terms of diagnostic recovery, symptom reductions, and clinically significant change. This dissertation also examined predictors of long-term efficacy (e.g., age, gender, and other clinical characteristics) as well as the relative long-term efficacy of CBT for Hispanic/Latino and European American youth. ^ Participants consisted of 67 youth (age range 15–26 years; M = 19.43, SD = 3.02 years at time of follow-up assessment), (47.8% females, 37.3% Hispanic/Latino) who had participated in one of two clinical trials (Silverman et al., 1999a, b). After providing informed consent to participate in the long term follow-up, youths completed a diagnostic interview and a battery of questionnaires. Results indicated that treatment gains were maintained about 9.5 years after treatment was completed. Maintenance of treatment gains was evident in terms of diagnostic recovery, symptom reductions, and clinically significant change. Long-term treatment gains extended to both ethnic groups and the two ethnic groups were functionally equivalent along most indices examined. Analyses of predictors of long-term outcome showed that parent self-reported pre-treatment depression, youth-reported pre-treatment depression, and youths retrospective reports of negative life events were significantly associated with less favorable long-term gains in terms of total symptoms of anxiety at long-term follow-up. In terms of long-term sequelae, youths with less successful post-treatment outcomes reported seeking-out additional treatment as well as using/abused substances and substance dependence significantly more than youths with successful post-treatment outcomes. Results are discussed in terms of the contribution of the present study to knowledge base about the long-term efficacy of exposure-based CBT procedures for phobic and anxiety disorders in youth. Findings also are discussed in terms of the need to modify CBT procedures to target youths with less successful post-treatment outcomes. Limitations and future directions are presented. ^
