Abstract

ABSTRACT The purpose of this study is to investigate the explanatory value of the theory of planned behavior (TPB) to predict the intentions of physical activity in older adults with lower-extremity osteoarthritis. This is a cross-sectional study with a sample of 41 older adults (50+ years) with lower-extremity osteoarthritis. The instruments used were as follows: International Physical Activity Questionnaire, Knee Injury and Osteoarthritis Outcome Score, Hip disability and Osteoarthritis Outcome Score and TPB exercise scale. The Western Ontario and McMaster Osteoarthritis Index scores were calculated and used in the statistical analysis. Results revealed that attitudes and perceived behavioral control were statistically significant predictors of physical activity intentions. Attitudes and perceived behavioral control accounted for 46% of the variance in physical activity intentions. Subjective norms did not evidence a significant effect. Knowledge of the predictors of physical activity intentions can guide researchers and clinicians in the development of interventions that are tailored to the personal characteristics and needs of older adults with chronic diseases.

计划行为理论预测葡萄牙老年骨关节炎患者的身体活动

摘要本研究的目的是探讨计划行为理论在预测老年下肢骨关节炎患者体育活动意向方面的解释价值。这是一项横断面研究，以41名患有下肢骨关节炎的老年人（50岁以上）为样本。使用的工具如下：国际体育活动问卷、膝关节损伤和骨关节炎结果评分、髋关节残疾和骨关节病结果评分和TPB运动量表。计算西安大略和麦克马斯特骨关节炎指数得分，并将其用于统计分析。结果显示，态度和感知的行为控制是体育活动意向的统计学显著预测因素。态度和感知的行为控制占体育活动意向差异的46%。主观规范没有证明有显著影响。了解体育活动意向的预测因素可以指导研究人员和临床医生制定针对患有慢性病的老年人的个人特征和需求的干预措施。

期刊介绍： Activities, Adaptation, & Aging is the working tool for activity directors and all health care professionals concerned with the enhancement of the lives of the aged. Established as the primary journal for activity professionals, Activities, Adaptation & Aging provides a professional outlet for research regarding the therapeutic implications of activities on quality-of-life issues and overall life satisfaction for the elderly. The journal examines a wide spectrum of activities: activity-based intervention for persons with dementia; activity determinants in independent-living elderly; activity implications in a variety of settings; activity participation patterns; and activity implications for everyday practice.
