Validation of the Zung depression scale in a Jamaican population [abstract]

ABSTRACT

OBJECTIVE: To validate the Zung depression scale in a Jamaican population in order to incorporate its use in primary health care facilities. METHODS: The Zung depression scale is a 20-item questionnaire used in the evaluation and detection of depression in individuals. Four mental health officers administered the scale to a cohort of 584 persons at the Maxfield Park Health Centre. RESULTS: Approximately 17 percent of the sample fell in the category of moderate depression and 5 percent in the category of severe depression. These results are consistent with other international studies. Wide variations were seen in the age bands designated adolescent, young adult, adult and elderly. The results showed good internal consistency with Cronbach ‘ of 0.813. Factor analysis using principle component analysis and varimax rotation identified three factors positive outlook, physical activity and psychological symptoms. CONCLUSION: Overall, items were highly predictive of depression. (AU)
