| Perceived Physical Activity Benefits Scale (PABS) |
|---|
| Regular physical activity is essential for maintaining good health in older adults. |
| Older adults who engage in physical activity experience improved quality of life. |
| Exercise helps older adults maintain independence in daily activities. |
| Engaging in regular exercise reduces the risk of premature death in older adults. |
| The benefits of exercise outweigh the risks for most older adults. |
| Regular physical activity improves heart health and reduces the risk of cardiovascular disease. |
| Strength training exercises help prevent osteoporosis and maintain bone health. |
| Exercise can reduce the risk of falls by improving strength and balance. |
| Regular exercise enhances cognitive function and reduces the risk of dementia. |
| Physical activity can help manage chronic conditions such as diabetes and arthritis. |
| Older adults should engage in at least 150 minutes of moderate-intensity physical activity per week. |
| Strength training exercises should be performed at least twice a week for older adults. |
| Even light-intensity activities, such as walking, provide significant health benefits for older adults. |
| It is never too late for older adults to start exercising and gain health benefits. |
| Attitude Towards Physical Activities Scale (APAS) |
| I enjoy engaging in physical activity. |
| Exercise is an important part of a healthy lifestyle. |
| I feel motivated to exercise regularly. |
| I believe I can still benefit from exercise regardless of my age. |
| Exercising with others makes it more enjoyable for me. |
| I would be more likely to exercise if I had proper guidance. |
| Encouragement from family or friends increases my likelihood of exercising. |
| Physical Activity Practice Scale (PAPS) |
| I engage in physical activity at least 3 times a week. |
| I perform strength-training exercises at least twice a week. |
| I engage in moderate-to-vigorous physical activity for at least 150 minutes per week. |
| I incorporate light physical activities (e.g., walking, stretching) into my daily routine. |
| I participate in group-based or social exercise programs. |
| I do balance or flexibility exercises to prevent falls. |
| I track my physical activity levels using a device or app. |
| My healthcare provider has advised me (or the older adult I care for) to exercise regularly. |
| I (or the older adult I care for) follow an exercise plan or routine. |
