Psychometric properties of the Mississippi Scale for Combat-Related Posttraumatic Stress Disorder based on veterans’ period of service.

Abstract Background: The Posttraumatic Stress Disorder Checklist (PCL-5) is the most widely used screening tool in assessing posttraumatic stress disorder symptoms, based on the Diagnostic and Statistical Manual of Mental disorders (DSM-5) criteria. This study aimed to evaluate the psychometric properties of the newly translated Bangla PCL-5. Methods: A cross-sectional survey was carried out among 10,605 individuals (61.0% male; mean age: 23.6±5.5 [13-71 years]) during May and June 2020, several months after the onset of the COVID-19 outbreak in Bangladesh. The survey included Bangla PCL-5 and PHQ-9 depression scale. We used confirmatory factor analysis to test the four-factor DSM-5 model, the six-factor Anhedonia model, and the seven-factor Hybrid model. Results: Bangla PCL-5 displayed adequate internal consistency (Cronbach’s alpha = 0.90). The Bangla PCL-5 score was significantly correlated with scores of the PHQ-9 depression scale. Confirmatory factor analyses indicated the models had a good fit to the data, including the four-factor DSM-5 model, the six-factor Anhedonia model, and the seven-factor Hybrid model.Conclusions: The Bangla PCL-5 appears to be a valid and reliable psychometric screening tool that may be employed in the prospective evaluation of posttraumatic stress disorder in Bangladesh.

This work describes assessment of the psychometric properties of a self-report instrument, the Glover Vulnerability Scale.© This scale was administered to a total of 11 groups ( N = 695). Six of the groups were Vietnam combat veterans diagnosed as having Posttraumatic Stress Disorder ( n = 531). The estimate of internal consistency was .88; the test-retest correlation over 4 wk. was .81. Convergent and discriminant validations were satisfactory based on the pattern of the scale's correlations with relevant MMPI subscales and demographic data. Scale scores also discriminated levels of functioning within the population diagnosed with Posttraumatic Stress Disorder and discriminated veterans diagnosed with Posttraumatic Stress Disorder from patients with major depressive disorder and anxiety disorder. Principal component factor analysis gave a 4-factor solution: social comfort, vulnerability, paranoia, and family trust. Over-all, the findings strongly support the clinical application of the Vulnerability Scale.

Mississippi Scale

Consistent with prior research, 73 hospitalized male Vietnam veterans with combat-related Posttraumatic Stress Disorder (PTSD) reported high scores on Self-criticism as measured by the Depressive Experiences Questionnaire. Self-criticism scores predicted greater severity of PTSD (Mississippi scale) after controlling for symptomatic depression (MMPI-D scale), suggesting that the nature of depression in Posttraumatic Stress Disorder differs from that in major depressive disorder.
