Introduction: Dementia is a growing public health concern, especially with the increasing aging population. Adequate knowl edge and a positive attitude towards dementia are crucial for early detection, management, and reducing stigma. Aim/Objectives: This study aims to evaluate the effectiveness of a Structured Teaching Program (STP) on improving knowledge and attitude regarding dementia among adults in selected villages of Kolar. Methods: A quasi-experimental one-group pretest-posttest design was used. Sixty adults were selected using a non-probability convenient sampling technique. Data was collected using a Structured Knowledge Interview Schedule (SKIS) and a Structured Attitude Interview Schedule (SAIS). Participants underwent a pretest assessment, followed by an STP intervention, and a post test was conducted using the same tool. Descriptive and inferential statistics were used for data analysis. Results: The mean pretest knowledge score was 12.77 (SD = 2.168), which significantly improved to 21.9 (SD = 1.591) in the post-test (t = 24.231, p < 0.001). Similarly, the mean attitude score increased from 27.03 (SD = 5.129) to 31.13 (SD = 2.325) (t = 5.094, p < 0.001), indicating a statistically significant improvement. Conclusion: The findings suggest that the Structured Teaching Program was effective in enhancing knowledge and fostering a positive attitude towards dementia among adults. Such educational interventions can play a crucial role in community-based dementia awareness and prevention strategies.
