| dc.description.abstract | Background and Aim: This study reports on the development and validation of a questionnaire designed to assess the knowledge, attitudes, and practices (KAP) of South African dentists regarding Molar Incisor Hypomineralisation (MIH). Given the scarcity of validated instruments in African contexts, the primary aim was to create a psychometrically sound tool tailored to regional clinical, educational, and systemic realities. Materials and Methods: A comprehensive literature-informed KAP questionnaire was initially drafted and refined using feedback from a diverse panel of ten international experts, including representation from African countries, to ensure contextual and cultural relevance. The instrument was piloted with 63 South African dental professionals. Psychometric testing included the Content Validity Index (CVI), Cronbach’s alpha for internal consistency, and Gwet’s AC for intra-rater (test–retest) reliability. Results: The final questionnaire included a refined set of items across the knowledge, attitudes, and practices domains. Content validity was high (S-CVI/Ave = 0.91), reflecting strong expert consensus. Internal consistency was satisfactory for the attitudes (α = 0.746) and practices (α = 0.783) domains, with moderate reliability for the knowledge domain (α = 0.566). Iterative expert review enhanced construct clarity and clinical relevance. | |
