Association between self-efficacy and loss to follow-up in long-term periodontal treatment

To examine whether or not oral health care-specific self-efficacy can predict loss to follow-up for long-term periodontal treatment.

Our prospective cohort study enrolled 144 patients with chronic periodontitis. Patient self-efficacy was assessed on the initial visit using the self-efficacy scale for self-care (SESS). Participants were then followed for 30 months from the onset of periodontal treatment. The loss to follow-up is the main outcome variable. Multiple logistic regression analysis was conducted to examine the association between self-efficacy for self-care and loss to follow-up for periodontal treatment. Gender, age, number of teeth, probing depth, plaque control record (PCR) value, PCR improvement rate, general self-efficacy scale score, and SESS score were used as the independent variables, and loss to follow-up as a dependent variable.

A total of 67 patients were lost to follow-up over the course of the study. Compared with the high-scoring SESS group (60-75), the odds ratio of loss to follow-up for the middle- (54-59) and low-scoring groups (15-53) were 1.05 [95% confidence interval (CI): 0.36-3.07] and 4.56 (95% CI: 1.11-18.74), respectively.

Assessment of oral health care-specific self-efficacy may be useful in predicting loss to follow-up in long-term periodontal treatment.
