Motivation plays a crucial role in lifestyle modifications for disease control and preventing recurrent cardiac events. Higher motivation levels are associated with improved health outcomes, including adherence to a healthy diet and sustained behavior change. However, there is a lack of evaluation of instruments for assessing motivation to adhere to diet recommendations, specifically among patients in Thailand.
This study aimed to assess the psychometric validity of the Thai version of the Motivation for Healthy Eating Scale (MHES) in patients with acute coronary syndrome in Thailand.
The study was conducted between May and August 2022, involving 200 patients with acute coronary syndrome selected through multistage random sampling from tertiary care institutions in Bangkok, Thailand. The scale was translated from English to Thai using the back-translation method. Principal Component Analysis (PCA) and Cronbach's alpha were employed to evaluate the validity and reliability of the scale.
The Thai version of the MHES demonstrated satisfactory reliability with a Cronbach's alpha coefficient of 0.73. The analysis revealed four factors consisting of 16 items: 1) 'integrated and integrated regulation' with seven items, 2) 'intrinsic and external regulation' with three items, 3) 'introjected regulation' with three items, and 4) 'amotivation' with three items. These factors collectively explained 66.78% of the total variance.
The findings indicate that the Thai version of the MHES is a reliable and valid instrument for assessing motivation related to dietary behavior among Thai patients with acute coronary syndrome. Nurses and healthcare professionals can use this scale to evaluate the motivation of dietary behavior among this population, thereby facilitating targeted interventions and promoting positive health outcomes.
动机在通过改变生活方式来控制疾病和预防心脏事件复发方面起着至关重要的作用。较高的动机水平与改善健康结果相关，包括坚持健康饮食和持续的行为改变。然而，缺乏对评估坚持饮食建议动机的工具的评估，特别是在泰国患者中。
本研究旨在评估泰国版健康饮食动机量表（MHES）在泰国急性冠状动脉综合征患者中的心理测量效度。
该研究于2022年5月至8月进行，纳入了200例急性冠状动脉综合征患者，这些患者通过多阶段随机抽样从泰国曼谷的三级医疗机构中选取。该量表采用回译法从英文翻译成泰文。采用主成分分析（PCA）和克朗巴哈系数来评估该量表的效度和信度。
泰国版MHES表现出令人满意的信度，克朗巴哈系数为0.73。分析揭示了由16个项目组成的四个因素：1）“整合与整合调节”有7个项目，2）“内在与外在调节”有3个项目，3）“内摄调节”有3个项目，4）“无动机”有3个项目。这些因素共同解释了总方差的66.78%。
研究结果表明，泰国版MHES是评估泰国急性冠状动脉综合征患者饮食行为动机的可靠且有效的工具。护士和医疗保健专业人员可以使用该量表来评估该人群的饮食行为动机，从而促进有针对性的干预并促进积极的健康结果。
