This study aimed determine the structural relationship between psychological constructs of the transtheoretical model (TTM; processes of change, decisional balance, and exercise self-efficacy), motives for physical activity (PA), and amount of PA among Malaysians with type 2 diabetes mellitus (T2DM).
All participants were recruited from the Hospital Universiti Sains Malaysia using a cross-sectional study design with purposive) sampling method. A total of 331 participants were recruited for the present study. Before participation in the study, they were informed that participation in the study was totally voluntary. Those who agreed to participate voluntarily were required to complete the self-administered questionnaire set, which included the processes of change, decisional balance, exercise self-efficacy, physical activity and leisure motivation, and international physical activity questionnaires. Data analysis of structural equation modeling was performed using Mplus 8.
From the 331 participants, most of whom were male (52%) and Malay (89.4%), with a mean age of 62.6 years (standard deviation = 10.29). The final structural equation model fit the data well based on several fit indices [Root Mean Square Error of Approximation (RMSEA) = 0.059, Comparative Fit Index (CFI) = 0.953, Tucker-Lewis Index (TLI) = 0.925, Standardized Root Mean Square Residual (SRMR) = 0.031]. A total of 16 significant path relationships linked between the TTM, motives for PA, and amount of PA.
The pros of decisional balance, others' expectations, and psychological condition were constructs that directly affected PA, whereas the other constructs had a significant indirect relationship with the amount of PA. A positive mindset is crucial in deciding a behavioral change toward an active lifestyle in people with T2DM.
本研究旨在确定跨理论模型（TTM；变化过程、决策平衡和锻炼自我效能感）的心理结构与马来西亚 2 型糖尿病（T2DM）患者的身体活动（PA）动机和 PA 量之间的结构关系。
所有参与者均采用横断面研究设计和目的抽样法从马来西亚大学医院招募。共有 331 名参与者被招募参加本研究。在参与研究之前，他们被告知参与研究是完全自愿的。那些自愿参与的人需要完成自我管理的问卷，其中包括变化过程、决策平衡、锻炼自我效能感、身体活动和休闲动机以及国际身体活动问卷。使用 Mplus 8 进行结构方程建模数据分析。
在 331 名参与者中，大多数为男性（52%）和马来人（89.4%），平均年龄为 62.6 岁（标准差=10.29）。根据几个拟合指数，最终的结构方程模型很好地拟合了数据[近似均方根误差（RMSEA）=0.059，比较拟合指数（CFI）=0.953，塔克-刘易斯指数（TLI）=0.925，标准化均方根残差（SRMR）=0.031]。共有 16 条显著路径关系将 TTM、PA 动机和 PA 量联系起来。
决策平衡、他人期望和心理状况的优势是直接影响 PA 的结构，而其他结构与 PA 量有显著的间接关系。积极的心态对 2 型糖尿病患者积极生活方式的行为改变决策至关重要。
