Post-Traumatic Stress Disorder (PTSD) Symptoms in Adults with Psychiatric Disorders.

Abstract

This study explores unrecognised symptoms related to post-traumatic stress disorder (PTSD) in individuals with a range of psychiatric disorders in the absence of traumatic events. We also examine the association between PTSD symptoms, social interaction with peers and therapeutic alliance with mental health professionals. A purposive sample of 120 adults consecutively referred to the psychology department from September 2008 to September 2010 was included in this study. We used the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) to ascertain the presence of PTSD symptoms, social interaction levels and treatment alliance with health professionals. Individuals previously undiagnosed with PTSD, referred without any noted traumatic event had high levels of symptoms related to PTSD, as measured by the PK scale of the MMPI-2. The PK scale was significantly correlated with several MMPI-2 clinical scales, the Social Introversion Scale (Si) and the Treatment Alliance Scale (TRT) (p < 0.001). This study demonstrated the presence of symptoms related to PTSD in individuals with a range of psychiatric disorders despite the absence of reported trauma. The presence of symptoms related to PTSD may be associated with an indirect negative impact on social contacts and a poorer therapeutic alliance with mental health professionals. Investigating symptoms of PTSD during a psychological assessment even when trauma is not the presenting complaint is merited in most cases.
