Abstract

Purpose: This study aimed to develop and evaluate the validity and reliability of dentists' radiation protection knowledge, attitudes, and practices (DRP-KAPs) questionnaire.

Methods: 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.

Results: 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.

Conclusion: 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.

开发和验证摩洛哥牙医辐射防护知识、态度和实践问卷。

目的：本研究旨在开发和评估牙医辐射防护知识、态度和实践（DRP-KAPs）问卷的有效性和可靠性：本研究采用逐步法进行。第一步，在全面查阅文献后生成项目，以确定相关内容和领域。第二步，由七位专家通过面效和内容效度对问卷进行内容效度评估。对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（CVR）进行了评估。然后，在 10 名牙科医生中对问卷进行了预试，以进行表面验证。第三步，使用内部一致性（Kuder-Richardson-20（KR-20）和 Cronbach'sα）和重复测试（Kappa 和类内相关系数 [ICC]）方法对可靠性进行评估，由摩洛哥拉巴特-萨莱-凯尼特拉地区的 100 名牙医填写问卷：最终确定的 DRP-KAPs 问卷包含 41 个项目，涵盖知识、态度和实践 (KAPs)。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。在内部一致性信度方面，知识和实践领域的 KR-20 系数分别为 0.70 和 0.68，态度领域的 Cronbach alpha 为 0.73。DRP-KAPs 问卷具有良好的可靠性，态度项目的 ICC 系数为 0.57 至 0.95，知识和实践项目的 Kappa 系数分别为 0.64 至 1 和 0.77 至 1：开发的 DRP-KAPs 问卷具有可接受的内部一致性、良好的 ICC 和 Kappa 系数以及良好的内容效度指数，是评估牙科医生辐射防护情况的重要工具。

期刊介绍： Journal of Applied Clinical Medical Physics is an international Open Access publication dedicated to clinical medical physics. JACMP welcomes original contributions dealing with all aspects of medical physics from scientists working in the clinical medical physics around the world. JACMP accepts only online submission. JACMP will publish: -Original Contributions: Peer-reviewed, investigations that represent new and significant contributions to the field. Recommended word count: up to 7500. -Review Articles: Reviews of major areas or sub-areas in the field of clinical medical physics. These articles may be of any length and are peer reviewed. -Technical Notes: These should be no longer than 3000 words, including key references. -Letters to the Editor: Comments on papers published in JACMP or on any other matters of interest to clinical medical physics. These should not be more than 1250 (including the literature) and their publication is only based on the decision of the editor, who occasionally asks experts on the merit of the contents. -Book Reviews: The editorial office solicits Book Reviews. -Announcements of Forthcoming Meetings: The Editor may provide notice of forthcoming meetings, course offerings, and other events relevant to clinical medical physics. -Parallel Opposed Editorial: We welcome topics relevant to clinical practice and medical physics profession. The contents can be controversial debate or opposed aspects of an issue. One author argues for the position and the other against. Each side of the debate contains an opening statement up to 800 words, followed by a rebuttal up to 500 words. Readers interested in participating in this series should contact the moderator with a proposed title and a short description of the topic
