Conducting research in global applied settings necessitates the use of easily administered, brief, and evidentiary measures. One widely used, brief self-report measure of posttraumatic stress disorder (PTSD) symptoms in children and adolescents is the Child PTSD Symptom Scale for DSM-5-Self-Report (CPSS-5-SR). The present study examined the factor structure, measurement invariance, reliability, and convergent validity of the Spanish translation of the CPSS-5-SR in a sample of 1,296 third- through 12th-graders in El Salvador (M age = 12.73 years, SD = 2.67, 55.2% female, 100.0% Latinx). This sample was collected as part of a government-led initiative to conduct broad school-based psychopathology screening, with the wider goal of introducing trauma-informed services into El Salvador's school system. Consistent with prior research, confirmatory factor analysis indicated that the four-factor DSM-5 model displayed a strong fit with the data. Measurement invariance by gender was also examined, with results showing invariance at the configural, metric, and scalar levels, indicating strong evidence that participants' patterns of response did not differ by gender. The results also indicated strong reliability, Cronbach's α = .91, and convergent validity with measures of commonly comorbid psychopathology, rs = .43-.68. Total scale norms derived from the current sample are provided. These findings highlight the considerable levels of posttraumatic stress experienced by Salvadorian youth and the importance of establishing evidentiary measures of psychopathology that can be used in diverse global populations. In particular, psychometric research represents the first step in augmenting efforts to screen, refer, and treat youth impacted by violence across the globe.
