ABSTRACT
Youth exposed to natural disasters are at risk of developing trauma-related symptoms as well as engaging in substance use. Although previous research has established associations between disaster-related stressors and substance use in youth, less has focused on how symptoms of posttraumatic stress disorder (PTSD) may underpin this association. The current study used network analysis to identify specific PTSD symptoms associated with substance use following a natural disaster. Participants were 91,732 youths (Grades 3-12) from across Puerto Rico who completed a needs assessment 5-9 months after Hurricane Maria made landfall in September 2017. We examined associations between PTSD symptoms and substance use, identified clusters of symptoms and bridges between them, and explored age- and binary gender-related differences in associations between specific PTSD symptoms and substance use. Analyses identified two symptom communities: (a) arousal and reactivity, negative alterations in cognition and mood, and substance use, and (b) avoidance and intrusion. Broader findings suggested that substance use was most strongly associated with PTSD-related irritability and angry outbursts among youths. Surrounding nodes explained only 4.1% of the variance in substance use, but this was higher among youths who reported not having a supportive adult, R2 = 8.5; friend, R2 = 7.9; or teacher/counselor, R2 = 7.7, in their life. The bridge symptoms of sleep disruption and physiological reactivity were identified as potentially critical intervention targets for disrupting PTSD symptom networks after a natural disaster. Implications for triaged mental health care following natural disasters and directions for future research are discussed.

Background: Knowledge regarding barriers faced by Latina/o/x caregivers in accessing youth mental health services (MHS) have largely depended on resource intensive interview-based assessments. Objective: We evaluated a questionnaire for Latina/o/x caregivers of youths that presents a briefer and more feasible alternative. Method: We conducted a psychometric evaluation of the Barriers to Treatment Questionnaire - Latina/o/x Caregivers (BTQ-LC) with a sample of 598 Latina/o/x caregivers from across the United States. Descriptive statistics and confirmatory factor analyses were used to identify common barriers to services, confirm the factor structure of the scale, and establish construct validity. Results: Descriptive statistics suggest that not knowing where and how to access services, and normalization of youth psychopathology were the most frequently reported barriers among caregivers of youth with clinically elevated problems on the CBCL. Confirmatory factor analysis suggests that the BTQ-LC was best represented by a three-factor structure: (1) structural, (2) perceptions regarding mental health problems, and (3) services. Our finding suggest that the BTQ-LC could also be used as a single factor as fit indices ranged from acceptable to poor. BTQ-LC scales were all negatively correlated with the utilization of common youth MHS (i.e., psychological counseling, medical doctors, school professionals). Conclusions: The BTQ-LC represents an important step towards improving our understanding and assessment of barriers to services contributing to mental health disparities among Latina/o/x youths.
