Aim: This article aims to develop and validate a questionnaire to assess the patient-based outcomes following periodontal therapy (QPBOPT).
Materials and methods: Questionnaire (QPBOPT) was formulated with 14 items, considering patient-based outcomes after periodontal therapy. Content validation was undertaken by seven experts in the field of periodontology and the questionnaire was pilot tested. Reliability was assessed using Cronbach's alpha and test–retest methods. The questionnaire was administered among 140 subjects, aged between 30 and 55 years who underwent periodontal flap surgery for periodontitis. Construct validity was done through principal component factor analysis.
Results: Cronbach's alpha for the overall scale was 0.98 in this study, indicating a high correlation between the items, and the questionnaire was found to be reliable. Factor analysis explained a cumulative variance of 95.909%, which proved all the 14 items to be valid.
Conclusion: Analysis of the data presented here shows that the questionnaire is valid and reliable for assessing the patient-based outcomes following periodontal therapy.
Clinical significance: This questionnaire can be a very effective objective tool for the assessment of the treatment outcome following periodontal therapy.
