Exploring the relationship between alienation appraisals, trauma, posttraumatic stress, and depression

Area of Science:

• Psychology
• Clinical Psychology
• Trauma Studies

Background:

• Cognitive models link negative trauma appraisals to posttraumatic stress disorder (PTSD) symptoms.
• Alienation appraisals, characterized by disconnection from self and others, are increasingly recognized as significant in trauma-related distress.
• Prior research indicates alienation appraisals fully mediate the link between trauma exposure and PTSD in adults.

Purpose of the Study:

• To investigate the role of alienation appraisals in mediating the relationship between cumulative trauma and trauma-related distress in student and clinical samples.
• To explore whether alexithymia, social support, and loneliness also mediate this relationship, clarifying alienation's specific role.

Main Methods:

• Mediation and hierarchical regression analyses were employed.
• Questionnaire data were collected from a student sample (N=100) and a clinical sample of trauma-exposed adults (N=93).

Main Results:

• In students, alienation fully mediated cumulative trauma's link to posttraumatic stress.
• In the clinical sample, alienation appraisals were the primary predictor of posttraumatic stress and a strong predictor of depression.
• Alienation appraisals emerged as a significant mediator/predictor across both samples, outperforming other explored factors like alexithymia, social support, and loneliness in some analyses.

Conclusions:

• Alienation appraisals are a key predictor of posttraumatic distress.
• Clinical evaluation of alienation is recommended to guide psychological interventions for individuals with trauma histories.
