    ObjectiveWe assessed the interaction between self-efficacy and joint problems and self-efficacy and visual problems on the risk of hearing aid abandonment in older adults. DesignA retrospective cohort study comprising older adults who received hearing aids in Chile was conducted. Hearing aid self-efficacy was measured using the S-MARS-HA questionnaire, while joint and visual problems were assessed through self-reported questions. Survival regression models were conducted to investigate the interaction between self-efficacy and joint problems, as well as self-efficacy and visual problems. Study sampleThe study included 355 older adults who received hearing aids through the Chilean public health sector. ResultsA significant interaction effect indicated that the relationship between self-efficacy and the risk abandonment was influenced by joint problems (p < 0.05). In the subpopulation with joint problems, self-efficacy was associated with a reduced risk of hearing aid abandonment (HR = 0.81), whereas in the subpopulation without joint problems, the protective effect was more pronounced (HR = 0.52). The interaction between self-efficacy and visual problems was not significant. ConclusionsThe interaction between self-efficacy and joint problems was associated with the risk of abandonment. Addressing limitations associated with joint problems and individuals' confidence in using their hearing aids could reduce the abandonment.
