(2010) 17(Suppl 1):S1-S329 nurses and social workers and compare it with that of psychiatry residents and nurses and to explore the attitudes of the same groups toward the elderly. It was expected that the study results would provide relevant inputs towards developing continuing professional education methods for primary care professionals and to enable them to care for old age mental problems The participants of this study were primary care health workers, nurses and physicians. The reference group for comparison comprised psychiatry residents and nurses. All were administered knowledge and attitude questionnaire. Background questionnaire covering previous psycho-geriatric education, work experience and need for further training was collected and the data were assessed as group mean comparisons. Psycho-geriatric knowledge was measured by a 40-item knowledge test on psychopharmacology, clinical syndromes, assessment, old age and psychotherapy. The attitudes were measured by a 30-item Likert-type questionnaire. The geriatric psychiatry knowledge level and the reported attitudes toward care of the elderly of the primary care groups were significantly lower than the reference group. The discrepancy was attributed to lack of adequate training and undergraduate education.
