PMID 31508444WHAT IT FOUND
A new questionnaire for chronic periodontitis patients asks about brushing, dental visits, habits and coping.
Answers were consistent, stable in a 2-week retest, and matched an existing self-management scale.
Key findings
01The final questionnaire was organised into three domains: CP-medical management with 12 items, CP-role management with 7 items, and CP-emotional management with 5 items.
02Responses on the whole questionnaire were consistent (Cronbach's α 0.931), and when 30 patients answered again after 2 weeks their scores were stable (coefficient 0.825).
03The whole questionnaire had a correlation coefficient of 0.869 with the behaviour part of the Chronic Disease Self-management Study Measure.

What it does not show
It was developed and tested in one Chinese tertiary stomatology hospital, and participants were recruited by convenience sampling, so it may not fit patients from other regions, languages or care settings. The authors did not perform confirmatory factor analysis, so the three-domain structure needs testing in new samples. Only patients were interviewed during development; dentists and nurses were not included. The study measured questionnaire properties, not whether the questionnaire improves patient education, self-management or periodontal health. The retest sample was only 30 patients.
Declared interests
The authors declared no conflicts of interest, and the study received no funding.
The easy way to misread this
Do not read this as evidence that periodontitis self-management education works. The study tested a questionnaire's consistency and relationship to another scale, not the effect of using it in care. It was also tested only in Chinese outpatients with chronic periodontitis at one hospital.
