To assess the compliance of Daily Disposable Contact Lenses (DDCLs) wearers with replacing lenses at a manufacturer-recommended replacement frequency. To evaluate the ability of two different Health Behavioural Theories (HBT), The Health Belief Model (HBM) and The Theory of Planned Behaviour (TPB), in predicting compliance.
A multi-centre survey was conducted using a questionnaire completed anonymously by contact lens wearers during the purchase of DDCLs.
Three hundred and fifty-four questionnaires were returned. The survey comprised 58.5% females and 41.5% males (mean age 34±12years). Twenty-three percent of respondents were non-compliant with manufacturer-recommended replacement frequency (re-using DDCLs at least once). The main reason for re-using DDCLs was "to save money" (35%). Predictions of compliance behaviour (past behaviour or future intentions) on the basis of the two HBT was investigated through logistic regression analysis: both TPB factors (subjective norms and perceived behavioural control) were significant (p<0.01); HBM was less predictive with only the severity (past behaviour and future intentions) and perceived benefit (only for past behaviour) as significant factors (p<0.05).
Non-compliance with DDCLs replacement is widespread, affecting 1 out of 4 Italian wearers. Results from the TPB model show that the involvement of persons socially close to the wearers (subjective norms) and the improvement of the procedure of behavioural control of daily replacement (behavioural control) are of paramount importance in improving compliance. With reference to the HBM, it is important to warn DDCLs wearers of the severity of a contact-lens-related eye infection, and to underline the possibility of its prevention.
评估日抛型隐形眼镜（DDCLs）佩戴者按照制造商推荐的更换频率更换镜片的依从性。评估两种不同的健康行为理论（HBT），即健康信念模型（HBM）和计划行为理论（TPB）对依从性的预测能力。
进行了一项多中心调查，使用的问卷由隐形眼镜佩戴者在购买DDCLs时匿名填写。
共收回354份问卷。调查对象中女性占58.5%，男性占41.5%（平均年龄34±12岁）。23%的受访者未遵循制造商推荐的更换频率（至少重复使用一次DDCLs）。重复使用DDCLs的主要原因是“省钱”（35%）。通过逻辑回归分析研究了基于两种HBT对依从行为（过去行为或未来意图）的预测：TPB的两个因素（主观规范和感知行为控制）均具有显著性（p<0.01）；HBM的预测性较差，仅严重程度（过去行为和未来意图）和感知益处（仅针对过去行为）为显著因素（p<0.05）。
不遵守DDCLs更换规定的情况很普遍，影响了四分之一的意大利佩戴者。TPB模型的结果表明，与佩戴者关系密切的人的参与（主观规范）以及改善日常更换行为控制程序（行为控制）对于提高依从性至关重要。关于HBM，重要的是要警告DDCLs佩戴者与隐形眼镜相关的眼部感染的严重性，并强调预防的可能性。
