The present research aimed to develop and validate a standardised survey instrument for the assessment of patients' awareness of the quality of their oral hygiene performance.
A digital questionnaire was developed that assesses both patients' naïve self-perceptions of oral cleanliness (SPOC) after tooth brushing and patients' perceptions after being informed how oral cleanliness may be captured in dentistry (SPOC). Three studies (N = 56 adults, N = 66 adolescents and one of their parents, N = 24 university students) assessed the instrument's feasibility (patient reports), reliability (internal consistency), validity (correlation with other constructs; sensitivity to manipulation of actual tooth brushing), and the correlation with actual oral cleanliness after tooth brushing.
All study groups accepted the questionnaire well; average answering times were less than 5 min. Cronbach's α exceeds 0.90; correlational analyses support the discriminant validity regarding oral hygiene related self-efficacy expectations and stages of change; manipulation of oral hygiene behaviour results in the expected changes of SPOC scores. Patients' SPOC correlate only moderately with actual oral cleanliness. The comparison between SPOC scores and actual oral cleanliness indicate that they considerably overestimate their oral hygiene performance.
The SPOC questionnaire is an easy-to-use, well-accepted, reliable and valid instrument for the assessment of patients' awareness of the quality of their oral hygiene for research and clinical purposes. The results of the questionnaire may help to reveal unrealistic self-perceptions of patients regarding their oral hygiene. It can raise their awareness of the need to improve their skills and/or efforts in this regard. Trial registration The third study was an interventional study and was registered in the appropriate national register ( www.drks.de ; ID: DRKS00018781; date of registration: 12/09/2019).
本研究旨在开发和验证一种标准化的调查工具，用于评估患者对口腔卫生质量的认知。
开发了一种数字问卷，评估患者在刷牙后对口腔清洁的天真自我感知（SPOC）和在被告知口腔清洁如何在牙科中捕捉后对口腔清洁的感知（SPOC）。三项研究（N=56 名成年人、N=66 名青少年及其父母中的一名、N=24 名大学生）评估了该工具的可行性（患者报告）、可靠性（内部一致性）、有效性（与其他结构的相关性；对实际刷牙行为的操纵的敏感性），以及与刷牙后实际口腔清洁的相关性。
所有研究组都很好地接受了问卷；平均回答时间不到 5 分钟。Cronbach's α 超过 0.90；相关分析支持与口腔卫生相关自我效能期望和改变阶段的区别有效性；口腔卫生行为的操纵导致 SPOC 评分的预期变化。患者的 SPOC 仅与实际口腔清洁中度相关。SPOC 评分与实际口腔清洁的比较表明，它们极大地高估了自己的口腔卫生表现。
SPOC 问卷是一种易于使用、易于接受、可靠且有效的工具，可用于评估患者对口腔卫生质量的认知，用于研究和临床目的。问卷的结果可能有助于揭示患者对口腔卫生的不切实际的自我认知。它可以提高他们在这方面提高技能和/或努力的意识。试验注册：第三项研究是一项干预性研究，并在适当的国家登记处（www.drks.de；ID：DRKS00018781；登记日期：2019 年 9 月 12 日）进行了登记。
