The GHQ-12 for the Assessment of Psychological Distress of Family Caregivers

Abstract

This study examined the utility of the 12-item General Health Questionnaire (GHQ-12) to assess the psychological distress of family caregivers. To accomplish this goal, a sample of 172 caregivers, 25 men and 147 women, aged 56.6 (SD = 13.7) completed self-report questionnaires and provided data on demographic factors. Univariate and bivariate models adjust adequately, although the two-factor model (anxiety/depression and social dysfunction) presented a better fit. Relative caregivers scored higher in psychological distress (anxiety and depression levels) on the GHQ-12 than did the normal population. In conclusion, the GHQ-12 is a sensitive instrument to detect the presence of anxiety and depression in relative caregivers, and the external validity of the instrument is generally adequate. The GHQ-12 seems particularly appropriate for research and clinical and health intervention in caregivers. Implications and limitations of these results are discussed, along with suggestions for future research.
