title: The Mental Vulnerability Questionnaire: a psychometric evaluation.
abstract: The Mental Vulnerability Questionnaire was originally a 22 item scale, later reduced to a 12 item scale. In population studies the 12 item scale has been a significant predictor of health and illness. The scale has not been psychometrically evaluated for more than 30 years, and the aim of the present study was both to evaluate the psychometric properties of the 22 and 12 item scales and of three new scales. The main study sample was a community sample comprising more than 6,000 men and women. In this sample the coefficients of homogeneity were all over 0.30 for the three new scales, but below 0.30 for the 12 and the 22 item scales. All five Mental Vulnerability scales had positively skewed score distributions which were associated significantly with both SCL-90-R symptom scores and NEO-PI-R personality scales (primarily Neuroticism and Extraversion). Coefficient alpha was highest for the 22 and 12 item scales, and the two scales also showed the highest long-term stability. The three new scales reflect relatively independent dimensions of Psychosomatic Symptoms, Mental Symptoms, and Interpersonal Problems, but because of reliability problems it remains an open question whether they will prove useful as predictors of health and morbidity.
