The impact of trauma core dimensions on anxiety and depression: a latent regression model through the Post-Traumatic Symptom Questionnaire (PTSQ). | LitMetric

AI Article Synopsis

  • Adverse life events can trigger traumatic responses, leading to symptoms such as intrusive thoughts and heightened anxiety and depression, which highlights the importance of effective assessment tools like the Post-Traumatic Symptom Questionnaire (PTSQ).
  • This study involved 761 participants to evaluate the PTSQ's psychometric properties and establish clinical cut-offs, confirming its reliability as a measurement tool for trauma-related symptoms.
  • It also explored how different trauma components—intrusion, avoidance, and hyperarousal—specifically impact anxiety and depression, advocating for targeted interventions to address the psychological distress following such experiences.

Article Abstract

Adverse life events (e.g., severe accidents, violence/abuse, organic disorders) can elicit traumatic responses characterized by intrusive thoughts, hyperarousal, and avoidance-highlighting the need for sound assessment tools. Also, these traumatic components could heighten anxiety and depression symptoms. This study aims included to: (1) assessing the psychometric properties of the Post-Traumatic Symptom Questionnaire (PTSQ) and delineating clinical cut-offs; (2) investigating how distinct trauma components contribute to anxiety and depression symptoms. Involving 761 participants who experienced a traumatic event, Part I tested the PTSQ psychometric properties, defining clinical cut-offs. Part II tested the impact of traumatic components on anxiety and depression symptoms, using a multiple multivariate latent regression model. PTSQ exhibited exemplary fit indices and robust psychometric properties. Clinically relevant cut-offs were identified. The differential contributions of intrusion, avoidance, and hyperarousal to anxiety and depression symptoms were evaluated, elucidating the strength and nature of these relationships. This study reaffirms the PTSQ as a psychometrically sound and reliable instrument. It underscores the effects of intrusion, avoidance, and hyperarousal on anxiety and depression symptoms in individuals with traumatic experiences. These insights advocate for evidence-based interventions aimed at alleviating the psychological suffering associated with trauma components, fostering adaptation and supporting psychological health.
