Developing the Social Cognitive Factor Scale (SCFS) to Analyze the Determinants Influencing the Utilization of Traditional Chinese Medicine Preventive Health Services among Older Adults

Introduction Traditional Chinese medicine (TCM) boosts immunity, aids self-repair, and supports elderly health. Despite government efforts, older adults underutilize TCM preventive health services. This study aimed to develop a reliable and valid Social Cognitive Factor Scale (SCFS) to understand this from a behavioral psychology perspective. Methods The SCFS, a self-report questionnaire rooted in Bandura's social cognitive theory, was developed by an expert panel using insights from current literature, focus group qualitative research, and scale testing. Twenty experts in TCM public health research and 840 community-dwelling older adults were included in this study. Scale development involved a literature review to establish the initial item pool, two Delphi expert consultations for item screening and revision, and comprehensive testing for reliability and effectiveness. Results The SCFS consisted of 22 items classified into six dimensions: perceived environment, social support, belief and knowledge, self-efficacy, outcome expectations, and self-regulation. The overall Cronbach's alpha of the scale was 0.946, and the split-half reliability of the total scale was 0.828, showing good reliability. A total of six factors were extracted, explaining 78.85% of the total variation. Exploratory factor analysis showed that the scale had good construct validity. Scores on the SCFS were significantly and positively correlated with the utilization rate of TCM preventive health services for older adults (r = 0.537, p < 0.01). Conclusion TCM plays a significant role in actively addressing the challenges of aging. The SCFS provides a reliable and valid tool for understanding the underutilization of TCM preventive health services among older adults. A positive correlation with service utilization rates highlights its potential for guiding interventions.
