Exercise adherence involves a number of sociocognitive factors that influence the adoption and maintenance of regular physical activity. Among trait-like factors, self-motivation is believed to be a unique predictor of persistence during behavior change. The aim of this study was to validate the factor structure of a French version of the Self-Motivation Inventory (SMI) and to provide initial convergent and discriminant evidence for its construct validity as a correlate of exercise adherence.
Four hundred seventy-one elderly were recruited and administered the SMI-10. Structural equation modeling tested the relation of SMI-10 scores with exercise adherence in a correlated network that included decisional balance and perceived quality of life.
Acceptable evidence was found to support the factor validity and measurement equivalence of the French version of the SMI-10. Moreover, self-motivation was related to exercise adherence independently of decisional balance and perceived quality of life, providing initial evidence for construct validity.
运动坚持涉及许多社会认知因素，这些因素会影响规律体育活动的采用和维持。在类似特质的因素中，自我激励被认为是行为改变期间坚持的独特预测因素。本研究的目的是验证法语版自我激励量表（SMI）的因子结构，并为其作为运动坚持相关因素的结构效度提供初步的聚合和区分证据。
招募了471名老年人并对其进行了SMI - 10测试。结构方程模型在一个包含决策平衡和感知生活质量的相关网络中测试了SMI - 10得分与运动坚持之间的关系。
发现有可接受的证据支持法语版SMI - 10的因子效度和测量等效性。此外，自我激励与运动坚持相关，独立于决策平衡和感知生活质量，为结构效度提供了初步证据。
