The purpose of this study was to examine the relationship of perceived risk, outcome expectancies, and perceived self-efficacy to intention and in turn exercise behavior. A convenience sample of people 18 years or older (N = 645) was recruited from public locations in Thailand. A descriptive cross-sectional design was used with self-administered questionnaires. Path models were estimated using Amos 18. Outcome expectancies and perceived self-efficacy indirectly influenced exercise behavior via intention. Unexpectedly, perceived risk of heart disease did not contribute to the model. Differences were found across age and gender groups. The final models showed a better fit in the middle-aged group, χ2(1) = 0.374, p = .541, and in women, χ2(1) = 0.197, p = .657, than in younger individuals and men. Interventions that enhance intention to exercise through outcome expectancies and perceived self-efficacy may be effective. Interventions may be more effective if they target particular age and gender groups.
本研究的目的是检验感知风险、结果期望和感知自我效能与锻炼意图进而与锻炼行为之间的关系。从泰国公共场所招募了18岁及以上的便利样本（N = 645）。采用描述性横断面设计，使用自填式问卷。使用Amos 18估计路径模型。结果期望和感知自我效能通过意图间接影响锻炼行为。出乎意料的是，心脏病的感知风险对该模型没有贡献。在年龄和性别组之间发现了差异。最终模型在中年组（χ2(1) = 0.374，p = 0.541）和女性组（χ2(1) = 0.197，p = 0.657）中比在年轻个体和男性中拟合得更好。通过结果期望和感知自我效能增强锻炼意图的干预措施可能是有效的。如果针对特定的年龄和性别组，干预措施可能会更有效。
