Second, patients often do not associate their symptoms with traumatic experiences and because of denial and minimization or out of shame, they can be reluctant to disclose their traumatic events. Therefore, the initial clinical presentation might be comorbid psychiatric disorder such as depression, substance abuse, or other anxiety disorders. First, PTSD typically co-exists with other psychiatric disorders ( 7). This is in part due to difficulties encountered by clinicians when a PTSD diagnosis is needed. Despite the high rates of PTSD is reported among psychiatric patients, most public mental health facilities and psychiatric clinics do not routinely evaluate for history of trauma or PTSD or provide specialized trauma-related services ( 6).
#Mmpi 2 validity and reliability full
Nearly one-third of psychiatric outpatients are diagnosed with lifetime history of full (20%) or subthreshold (9%) PTSD ( 5). In primary care, the adjusted current prevalence rate for full or subsyndromal PTSD is 11.8% ( 4). PTSD is far more prevalent in clinical populations. In Korea, one epidemiological study reported a life-time trauma experience rate of 78.8% and a life-time PTSD prevalence of 4.7% among adults living in an urban area ( 3).
According to a US epidemiological study, 60.7% of men and 51.2% of women in the general population have experienced at least one traumatic event in their lifetime, and the life-time prevalence of PTSD in the US general population is 7.8% ( 2). The core symptoms of PTSD are re-experiencing, avoidance, negative alterations in cognitions and mood, and increased arousal ( 1). Post-traumatic stress disorder (PTSD) is characterized by specific sets of symptoms that develop after exposure to actual or threatened death, serious injury, sexual violence, or work-related aversive details. This study demonstrated the favorable psychometric prosperities of the Korean version of the SCL-PTSD, supporting its use in clinical research and practice. Concurrent validity was demonstrated by significant correlation with the IES-R score. Convergent validity was confirmed because the scores of the SCL-PTSD were significantly correlated with BDI, SAI and TAI scores.
In comparison with other diagnostic groups, the scores of the SCL-PTSD were significantly higher compared to those of adjustment disorder, depression, other anxiety disorders, and schizophrenia, demonstrating its criteria-related validity. The Korean version of the SCL-PTSD showed excellent internal consistency and moderate-to-good four-week temporal stability in both the interpersonal and non-interpersonal trauma groups. Self-report data of the SCL-PTSD, Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Impact of Events Scale-Revised (IES-R) were gathered.
This study investigates the reliability and validity of the Korean version of the SCL-PTSD among 104 psychiatric outpatients with PTSD, caused by interpersonal (n = 50) or non-interpersonal trauma (n = 54). However, the psychometric properties have not been investigated in a clinical setting for patients with PTSD from diverse traumatic events. The Symptom Checklist - Post-Traumatic Stress Disorder Scale (SCL-PTSD), also known as Crime-Related PTSD Scale has been validated in survivors of interpersonal trauma in the general population.
