This study aimed to develop and evaluate the validity and reliability of dentists' radiation protection knowledge, attitudes, and practices (DRP-KAPs) questionnaire.
This study was conducted using a stepwise approach. In the first step, items were generated to determine the relevant content and domains after a thorough literature review. In the second step, the content validity of the questionnaire was assessed by seven experts using face and content validity. The content validity index for relevance and clarity (I-CVI, S-CVI/Av, and S-CVI/UA) and the content validity ratio (CVR) were performed. Then, the questionnaire was pre-tested with 10 dentists for face validation. In the third step, reliability was assessed using internal consistency (Kuder-Richardson-20 (KR-20) and Cronbach's alpha) and test-retest (Kappa and intraclass correlation coefficient [ICC]) methods by filling out the questionnaire by 100 dentists practicing in the Rabat-Salé-Kénitra region, in Morocco.
The finalized DRP-KAPs questionnaire contains 41 items covering knowledge, attitudes and practices (KAPs). The I-CVIs, S-CVI/UA and S-CVI/AV and CVR values of the 41 items were ≥0.86 for each item, ≥0.82, ≥0.97, and ≥0.71, respectively. With regard to internal consistency reliability, the KR-20 coefficients for the knowledge and practice domains were 0.70 and 0.68, respectively, and the Cronbach alpha for the attitude domain was 0.73. The DRP-KAPs questionnaire has good reliability with the ICC coefficients for attitude items ranging from 0.57 to 0.95 and Kappa coefficients for knowledge and practice items ranging from 0.64 to 1 and 0.77 to 1, respectively.
The developed DRP-KAPs questionnaire was found to be a noteworthy tool for assessing radiation protection among dentists, with acceptable internal consistency, good ICC and Kappa coefficients, and good content validity indices.
本研究旨在开发并评估牙医辐射防护知识、态度和行为（DRP-KAPs）问卷的有效性和可靠性。
本研究采用逐步推进的方法。第一步，在全面的文献综述后生成项目，以确定相关内容和领域。第二步，由七位专家通过表面效度和内容效度评估问卷的内容效度。计算相关性和清晰度的内容效度指数（I-CVI、S-CVI/Av和S-CVI/UA）以及内容效度比率（CVR）。然后，对10名牙医进行预测试以进行表面效度验证。第三步，通过摩洛哥拉巴特-萨勒-凯尼特拉地区的100名执业牙医填写问卷，使用内部一致性（库德-理查森-20（KR-20）和克朗巴赫α系数）和重测（卡帕系数和组内相关系数[ICC]）方法评估可靠性。
最终确定的DRP-KAPs问卷包含41个涵盖知识、态度和行为（KAPs）的项目。41个项目的I-CVI、S-CVI/UA、S-CVI/AV和CVR值分别为每个项目≥0.86、≥0.82、≥0.97和≥0.71。关于内部一致性可靠性，知识领域和行为领域的KR-20系数分别为0.70和0.68，态度领域的克朗巴赫α系数为0.73。DRP-KAPs问卷具有良好的可靠性，态度项目的ICC系数范围为0.57至0.95，知识和行为项目的卡帕系数分别为0.64至1和0.77至1。
所开发的DRP-KAPs问卷被认为是评估牙医辐射防护的一个值得关注的工具，具有可接受的内部一致性、良好的ICC和卡帕系数以及良好的内容效度指数。
