This study examined the relationships between grit personality, self-efficacy, motivation (autonomous, controlled, and amotivation), and the readiness to change index toward exercise. Participants were 391 adults aged between 18 and 64 years old ( = 31.16; = 12.45) from Hermosillo, Sonora (Mexico) who completed questionnaires (i.e., the Grit Personality Scale, the Exercise Self-Efficacy Questionnaire, the Treatment Self-Regulation Questionnaire and the Stages of Change Questionnaire for Physical Activity) measuring the variables of interest. The reliability of the instruments was tested using Cronbach's alpha, whereas confirmatory factor analyses were performed for each instrument separately. A measurement model and a structural equation model were assessed as well. The results of the structural equations model showed that grit personality was positively associated with self-efficacy, and in turn, with autonomous motivation and with the readiness to change index. On the other hand, self-efficacy was negatively correlated with controlled motivation, and positively correlated with the readiness to change index. Finally, self-efficacy also showed a negative correlation with amotivation, which, in turn, was negatively correlated with the readiness to change index. These results provide information to develop psychological intervention programs based on grit personality and motivation, with the aim of increasing the number of participants who engage in exercise.
本研究考察了坚毅人格、自我效能感、动机（自主动机、受控动机和无动机）与运动改变意愿指数之间的关系。参与者为来自墨西哥索诺拉州埃莫西约的391名18至64岁的成年人（平均年龄 = 31.16岁；标准差 = 12.45岁），他们完成了测量相关变量的问卷（即坚毅人格量表、运动自我效能量表、治疗自我调节问卷和身体活动改变阶段问卷）。使用克朗巴哈系数对工具的信度进行了检验，同时对每个工具分别进行了验证性因素分析。还评估了一个测量模型和一个结构方程模型。结构方程模型的结果表明，坚毅人格与自我效能感呈正相关，进而与自主动机和改变意愿指数呈正相关。另一方面，自我效能感与受控动机呈负相关，与改变意愿指数呈正相关。最后，自我效能感也与无动机呈负相关，而无动机又与改变意愿指数呈负相关。这些结果为制定基于坚毅人格和动机的心理干预计划提供了信息，旨在增加参与运动的人数。
