To evaluate the reliability and validity of Arabic Rapid Estimate of Adult Literacy in Dentistry (AREALD-30) in Saudi Arabia.
A convenience sample of 200 subjects was approached, of which 177 agreed to participate giving a response rate of 88.5%. Rapid Estimate of Adult Literacy in Dentistry (REALD-99), was translated into Arabic to prepare the longer and shorter versions of Arabic Rapid Estimate of Adult Literacy in Dentistry (AREALD-99 and AREALD-30). Each participant was provided with AREALD-99 which also includes words from AREALD-30. A questionnaire containing socio-behavioral information and Arabic Oral Health Impact Profile (A-OHIP-14) was also administered. Reliability of the AREALD-30 was assessed by re-administering it to 20 subjects after two weeks. Convergent and predictive validity of AREALD-30 was evaluated by its correlations with AREALD-99 and self-perceived oral health status, dental visiting habits and A-OHIP-14 respectively. Discriminant validity was assessed in relation to the educational level while construct validity was evaluated by confirmatory factor analysis (CFA).
Reliability of AREALD-30 was excellent with intraclass correlation coefficient of 0.99. It exhibited good convergent and discriminant validity but poor predictive validity. CFA showed presence of two factors and infit mean-square statistics for AREALD-30 were all within the desired range of 0.50 - 2.0 in Rasch analysis.
AREALD-30 showed excellent reliability, good convergent and concurrent validity, but failed to predict the differences between the subjects categorized based on their oral health outcomes.
评估阿拉伯快速成人口腔 Literacy 评估工具(AREALD-30)在沙特阿拉伯的可靠性和有效性。
采用方便抽样法,共招募了 200 名受试者,其中 177 名同意参与,应答率为 88.5%。将快速成人口腔 Literacy 评估工具(REALD-99)翻译为阿拉伯语,以准备更长和更短的阿拉伯快速成人口腔 Literacy 评估工具版本(AREALD-99 和 AREALD-30)。每位参与者都提供了 AREALD-99,其中也包含了 AREALD-30 的单词。还发放了一份包含社会行为信息和阿拉伯口腔健康影响量表(A-OHIP-14)的问卷。采用重测信度评估 AREALD-30 的可靠性,在两周后对 20 名受试者进行重测。通过与 AREALD-99 和自我感知的口腔健康状况、牙科就诊习惯和 A-OHIP-14 的相关性评估 AREALD-30 的收敛和预测有效性。通过与教育水平的关系评估区分效度,通过验证性因素分析(CFA)评估结构效度。
AREALD-30 的可靠性非常好,组内相关系数为 0.99。它表现出良好的收敛和区分效度,但预测效度较差。CFA 显示存在两个因素,Rasch 分析中 AREALD-30 的 INfit 均方统计量均在 0.50-2.0 的理想范围内。
AREALD-30 显示出极好的可靠性、良好的收敛和同时有效性,但未能预测基于口腔健康结果分类的受试者之间的差异。
