Development of the self-efficacy scale for maternal oral care

This study's purpose was to develop a task-specific self-efficacy scale for maternal oral care (SESMO) with reliability and validity. Methods: A draft scale consisting of 36 items was designed and tested on 119 mothers at a dental clinic. Item analysis was performed to improve its accuracy by reducing the number of items. Internal consistency and test and retest stability were investigated. Concurrent validity was tested by examining associations of the SESMO score with the: general self-efficacy scale (GSES) score; number of decayed teeth; and frequency of tooth-brushing for children. Construct validity was examined by comparing the SESMO scores between mothers of children with caries at initial visit (Group 1) and those continuing regular dental checkups (Group 2). Results: The item analysis selected 16 items for the SESMO. Alpha coefficient of the SESMO was 0.82. Significant correlation was observed between tests and retests (r=0.74). There were significant associations between the SESMO score and GSES score (r=0.39); number of decayed teeth (r=-0.33); and frequency of brushing children's teeth (r=0.66). Group 2 had a significantly higher SESMO score than Group 1 (P<.001). Conclusions: The SESMO showed high reliability and validity. This scale might endure with research applications in pediatric dental practice.
