Psychophysiological Insights into Child-Centered Play Therapy for Trauma: A Case Study

Existing literature thoroughly reviews the detrimental consequences that adverse childhood experiences (ACEs) have physically, emotionally, neurobiologically, and financially. It is imperative to develop effective treatments that offer a sense of hope to children who have been impacted. The established relationship between high ACE scores and physiological hyperarousal due to emotional dysregulation is clear in the literature. This relationship indicates that taking psychophysiological measures may be an effective method of gauging the effectiveness of trauma treatments. This study measured the heart rate of a child who had experienced multiple ACEs, during 16 child-centered play therapy (CCPT) sessions, using the Empatica (E4) wristband. Bayesian change point analysis was conducted and multiple changes in the heart rate mean were detected and identified within each session’s time series. Additionally, changes in heart rate variability during the 16 sessions were observed and points of interest, e.g., highest and lowest observed heart rates, were noted. Results suggested the number of breakpoints in the heart rate means within each session, as well as the location, i.e., the time of each breakpoint, so that each significantly detectable change in heart rate mean as well as sessions of noted differences in heart rate variability were discussed alongside what was occurring within the video recorded sessions.
