Preliminary psychometrics of the Structured Trauma-Related Experiences and Symptoms Screener for Adults (STRESS-A) in an urban prenatal healthcare clinic.

ABSTRACT

OBJECTIVE: The primary objective of the current study was to examine preliminary psychometric characteristics of the Structured Trauma-Related Experiences and Symptoms Screener for Adults (STRESS-A), a novel self-report instrument that inventories childhood and adulthood trauma-related experiences and assesses symptoms of posttraumatic stress disorder (PTSD) according to the Diagnostic and Statistical Manual for Mental Disorders (5th ed.; [DSM-5] American Psychiatric Association, 2013). Designed for efficient administration and interpretation by nonclinically trained professionals, the STRESS-A is a promising tool for use in settings where mental health professionals are lacking. METHOD: A sample of 170 women in their third trimester of pregnancy and receiving services at an urban prenatal health care clinic completed the STRESS-A and a battery of instruments measuring mental health functioning, perceived stress, and emotion dysregulation. Tests of reliability and validity were conducted, including confirmatory factor analysis to examine the fit of STRESS-A symptom criteria relative to PTSD symptom structures supported in the literature. RESULTS: Results provide initial support for internal consistency, reliability, and convergent and construct validity in a largely Hispanic pregnancy sample. The STRESS-A symptom structure fit well with several that have been supported in the literature, including the 4-factor model of the DSM-5. CONCLUSION: The STRESS-A is a promising tool for assessing risk associated with trauma exposure and probable DSM-5-based PTSD. Findings support its utility in a high-risk pregnancy cohort, a population that is underserved, yet shows high rates of trauma exposure and associated symptoms. Addressing maternal trauma-related impairment may have important implications for healthy fetal and child development. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
