Anchored on the key constucts of Ajzen's Theory of Planned Behavior (1985), this paper seeks to test a model that explores the influence of knowledge, attitude, and caring behavior on nursing students' behavioral intention toward geriatric care. A five-part survey-questionnaire was administered to 839 third and fourth year nursing students from a comprehensive university in the Philippines. To delineate the underlying dimensions of knowledge, attitude, and caring behavior, an exploratory factor analysis (EFA) was carried out. The resulting factors were integrated in the proposed model prior to structural equation modeling (SEM). The emerging model shows that while knowledge did not directly influence intent, it had a direct impact in the development of attitudes. Impliedly, by delineating the variables through EFA, new relationships between specific knowledge, attitude, and caring behavior dimensions can be observed. As shown, a nursing student's intent to care for older people can be increased if he/she sees them as powerful and wise. On the other hand, if one sees older people as demanding in nature, he/she is less likely to pursue geriatric nursing in the future. Interestingly, the resulting structural model in this study has successfully and clearly delineated the positive and negative determinants of nursing students' intent to care for geriatric patients. The researchers hope that the model be used as an assessment tool for various nurse populations in order to effectively plan innovative strategies when introducing geriatric nursing.
