To assess the validity and reliability of a Parental Dental Concerns Scale (PDCS) to identify parents unable to access preventive dental care for their children.
Two studies were conducted. In Study One, a purposive convenience sample of 399 Scottish parents answered questions on going to the dentist, family life and demographics. Parents were retested eight weeks later. In Study Two, 574 Scottish parents participating in a preventive oral health programme were posted the same questionnaire. Information on child dental attendance was gained from dental records. Data were analysed using exploratory (EFA) and confirmatory (CFA) factor analysis. Internal consistency and test-retest correlations provided reliability estimates. Validity was assessed with confirmatory factor analysis, correlations and independent t-tests.
EFA indicated that the PDCS had a four factor structure, supported by a subsequent CFA. The PDCS and its four subscales had good internal consistency, concurrent validity and test-retest reliability. Further work is required to confirm the scale's predictive validity in discriminating between children and parents who did and did not attend the dental practice.
The PDCS is a reliable scale, which demonstrates good construct validity. Further testing is required to confirm its predictive validity.
评估父母牙科关注量表（PDCS）的有效性和可靠性，以识别无法为子女提供预防牙科保健的父母。
进行了两项研究。在研究一，399 名苏格兰父母参与了一项有目的的便利抽样调查，回答了关于看牙医、家庭生活和人口统计学的问题。八周后对父母进行了重测。在研究二，574 名参与预防口腔健康计划的苏格兰父母收到了相同的问卷。从牙科记录中获得有关儿童牙齿就诊的信息。使用探索性（EFA）和验证性（CFA）因子分析对数据进行分析。内部一致性和重测相关性提供了可靠性估计。验证性因子分析、相关性和独立 t 检验评估了有效性。
EFA 表明 PDCS 具有四因素结构，随后的 CFA 也支持了这一结构。PDCS 及其四个分量表具有良好的内部一致性、同时效度和重测信度。需要进一步的工作来确认该量表在区分是否去看牙医的儿童和父母方面的预测有效性。
PDCS 是一个可靠的量表，具有良好的结构有效性。需要进一步的测试来确认其预测有效性。
