Causal Complexity In Secondary Traumatic Stress Among Child Welfare Workers: An Application of Qualitative Comparative Analysis

Background

Child welfare workers are at a greater risk of Secondary Traumatic Stress (STS) due to their exposure to trauma in working with children and families. Multiple theories have identified various organizational conditions as key determinants of STS. However, they often assume that the effects on STS are linear, independent, and symmetrical. In reality, the same level of STS can result from different conditions. High STS can also arise from multiple combinations of conditions that coexist. Moreover, the conditions for high STS may not be simply the opposite of the conditions for low STS. This study applies Qualitative Comparative Analysis (QCA) to uncover such causal complexity and identify the necessary and sufficient conditions for the presence and absence of high STS among child welfare workers.

Methods

The sample involves 277 child welfare workers managing active cases from Wave 8 of the Florida Study of Professionals for Safe Families. STS was measured using 17 items assessing intrusion, avoidance, and arousal symptoms. High STS was calibrated into a fuzzy set based on a diagnostic guideline to determine a clinical level of STS (crossover point = 2.24). Seven organizational conditions were included: high workplace trauma exposure, low organizational justice, time pressure, high supervisory support, high peer support, high work-life balance, and high organizational cultural competence. Each condition was calibrated using theoretically grounded anchors and empirically balanced distributions. QCA analysis was conducted in R, along with logical minimization and enhanced standard analysis to ensure accurate and robust results.

Results

High workplace trauma exposure was found to be a necessary condition for high STS (consistency = .85, coverage = .56). Four sufficient pathways to high STS were identified (consistency = .80, coverage = .38). All the pathways involved the combination of high trauma exposure and low organizational justice, suggesting high STS occurred when both conditions were present at the same time within organizations. Notably, high peer support led to high STS when structural constraints such as high time pressure and poor work-life balance were present. Seven sufficient pathways to the absence of high STS were identified (consistency = .83, coverage = .52). The most important pathway included low trauma exposure combined with high supervisory support and work-life balance.

Discussions

Workplace trauma exposure is an essential precondition for high STS, highlighting the need to distribute trauma cases adequately and prevent workplace violence. Organizational justice emerged as an equally important condition for both the presence and absence of high STS. This suggests that fairness in resource distribution, decision-making, and interpersonal relationships should be included as another core principle in developing STS-informed organizations. The context-dependent role of peer support is noteworthy. Peer support may not be sufficient and can even be harmful when structural constraints are prevalent. Effective STS interventions should address multiple organizational conditions comprehensively and be tailored to the specific organizational contexts, rather than relying on a one-size-fits-all solution. Furthermore, different organizational approaches may be necessary depending on whether the goal is to prevent STS or to reduce existing STS symptoms.
