Mediating effect.

ObjectiveThe present study aimed to identify the social cognitive predictors of regular dental visits and mouth self-examination behaviors among the elderly population, based on the Health Action Process Approach (HAPA) model.BackgroundRegular dental visits and mouth self-examination can prevent oral and dental problems among the elders. Little information is available regarding the social cognitive predictive factors of these two behaviors.Materials and methodsA cross-sectional study was conducted in 24 municipality centers in Tehran, Iran in 2021. The centers were selected randomly using a multi-stage cluster sampling method and 301 elderly attendants aged 60≥years participated in the study. Data collection was done using a researcher-made questionnaire including demographic characteristics and the HAPA model constructs for two target behaviors. Data were analyzed using the Smart-PLS version 3.3.9 via correlation and PLS-SEM analysis.ResultsThe mean age of the participants was 65.3±5.33 years and 79.7% were female. The SEM analysis showed that Action Self-Efficacy [b (SD) = 0.595 (0.065), PConclusionAction self-efficacy predicted the intention for regular dental visits and mouth self-examination behaviors. The relationship between intention and both behaviors was mediated by Planning. Emphasis on improving Action Self-Efficacy and Intention formation will enhance the effectiveness of interventions aiming at promoting the oral health of the elderly population.
