Regular (daily) dental flossing is recommended for preventing oral diseases, but adherence is unsatisfactory. Social cognitive theory (SCT) specifies determinants of dental flossing: cognitions about risk, positive and negative outcome expectations and the perceived ability to perform behaviour predict motivation, which in turn predicts behaviour. Recent research suggests that motivation alone may not suffice to predict behaviour, and proposes if-then-planning. This study aims to predict flossing adherence from social cognitive variables and planning.
Questionnaire data from 157 non-dental university students on flossing, SCT variables and planning were gathered at three measurement points over 6 weeks. Residual floss was used to validate behaviour self-reports.
Social cognitive variables and planning correlated significantly with flossing at all times. Discriminant function analysis suggests that after controlling for Time 1 flossing, planning Time 2 (Wilk's lambda=0.77; p<0.01) is more important in discriminating between adherent and non-adherent participants at Time 3 than Time 1 social cognitive measures. Regression analyses confirmed this result with planning as only predictor of flossing change (p<0.05).
These results suggest targeting planning in interventions to increase compliance with flossing recommendations. Implications for such interventions are discussed.
推荐定期（每日）使用牙线以预防口腔疾病，但依从性并不理想。社会认知理论（SCT）明确了使用牙线的决定因素：对风险的认知、积极和消极结果期望以及对行为表现能力的感知预测动机，而动机又反过来预测行为。近期研究表明，仅靠动机可能不足以预测行为，并提出了“如果-那么”计划。本研究旨在通过社会认知变量和计划来预测使用牙线的依从性。
在6周内的三个测量点收集了157名非牙科专业大学生关于使用牙线、社会认知理论变量和计划的问卷数据。剩余牙线用于验证行为自我报告。
社会认知变量和计划在所有时间都与使用牙线显著相关。判别函数分析表明，在控制了第1次使用牙线的情况后，第2次计划（威尔克斯λ=0.77；p<0.01）在区分第3次时的依从者和非依从者方面比第1次社会认知测量更重要。回归分析证实了这一结果，即计划是使用牙线变化的唯一预测因素（p<0.05）。
这些结果表明，在干预措施中针对计划制定策略，以提高对使用牙线建议的依从性。并讨论了此类干预措施的意义。
