The Child PTSD Symptom Scale: Psychometric properties among earthquake survivors

From PubMed via Jisc Publications RouterEvidence for a single underlying factor structure of posttraumatic stress disorder (PTSD) in children remains elusive. We assessed the underlying factor structure of the Child PTSD Symptom Scale through exploratory (EFA) and confirmatory factor analyses (CFA) in 570 survivors of the 2015 Gorkha earthquake in Nepal. The EFA suggests that the three-factor DSM-IV model fit these data best. The CFA suggests that while the DSM-IV model adequately fit these data, the four-factor King model fit them better. There was no evidence of differential item functioning by age or gender, and internal consistency of the scale was high. PTSD (overall or by factor) was not correlated with functional impairment. Inconsistent psychometric results across contexts and methodologies suggest that our current theoretical conceptualizations and empirical models of posttraumatic stress are lacking. Future studies must both document the instrument properties to assure internal validity and cross-study comparisons and, bolstered by increased psychometric data and analyses, rework theoretical models of PTSD with improved cross-cultural validity.The research was funded by World Vision International (ended 2015), an elrha R2HC award from the Wellcome Trust and DFID (ended 2016), and additional funding from the National Institute of Mental Health (T32MH096724 and R01MH110872).
