The role of psychological defences in moderating between trauma and post‐traumatic symptoms among Palestinian men

Psychological defences are conceptualized as protective processes that help individuals to maintain their integrity in the face of threat and danger. Accordingly, their role in defending trauma victims from post‐traumatic symptoms was examined. The sample consisted of 128 Palestinian male political ex‐prisoners who had reported various degrees of torture and ill‐treatment. The first aim was to analyze the dimensionality and distribution of different defence mechanisms. The second was to examine which defences would moderate the association between the reported torture and ill‐treatment and the post‐traumatic symptoms (PTS). Third, the direct associations between reported torture and ill‐treatment and defences and between the defences and symptoms were explored. Defence mechanisms were assessed by a 40‐item version of the Defense Style Questionnaire (DSQ), and Post‐traumatic symptoms by the Harvard Trauma Questionnaire (HTQ), and experiences of torture and ill‐treatment by a scale developed for that purpose. The results show, first, that the men used predominantly mature defences such as anticipation, sublimation, suppression, and rationalization, but also relatively frequently somatization and dissociation, which are characteristic responses among trauma victims. Second, the principal component analysis revealed four defence dimensions, differentiated by the level of maturity and the approach to reality: the mature reality‐based, the consciousness‐limiting, the immature reality‐escaping, and the immature reality‐distorting defences. Third, against our hypothesis, the moderating analyses indicated that the reported torture and ill‐treatment were relatively more associated with vigilance, avoidance, and intrusion symptoms if men used consciousness‐limiting defences. Yet as expected, the mature reality‐based defences did not show a protective effect. Furthermore, a high level of reported torture and ill‐treatment was associated with a low level of the mature reality‐based defences, but not with a high level of immature defences. Last, similarly to earlier studies, the immature reality‐distorting and immature reality‐escaping defences associated directly with high, and mature reality‐based defences with low, levels of PTS‐symptoms.
