Evaluating the service quality in early intervention (EI) from the perspective of professionals with knowledge in this area is essential for the improvement of EI centres. In this study, we aimed to test the reliability and validity of the adapted Inventory of Quality in Early Intervention Centres-P (IQEIC-P) in a sample of professionals who worked in EI centres. Three hundred and twenty-four professionals of 85 EI Spanish centres were recruited for this research. Various psychometric analyses were used to evaluate the factorial structure, the internal consistency, factorial validity and construct validity. A 5-dimension structure was obtained in the exploratory factor analysis (EFA). The results showed an adequate internal consistency (Cronbach's alpha values between 0.71 and 0.83, and composite reliability (CR) values higher than 0.70), as well as satisfactory convergent and discriminant validity (average variance extracted (AVE) values above 0.50). In the confirmatory factor analysis, good model fit indicators were observed. The IQEIC-P showed adequate psychometric properties, demonstrating to be a valid instrument for the evaluation of service quality in EI centres from the perspective of professionals. The benefits will influence the professionals themselves, and they will have a positive and direct impact on the families that are attended to in these centres.
从专业人士的角度评估早期干预（EI）服务质量对于改善 EI 中心至关重要。在这项研究中，我们旨在测试经过改编的早期干预中心质量评估量表-专业版（IQEIC-P）在从事 EI 中心工作的专业人士样本中的信度和效度。为此研究共招募了 85 个西班牙 EI 中心的 324 名专业人士。采用各种心理测量学分析来评估因子结构、内部一致性、因子有效性和构念有效性。探索性因素分析（EFA）得出了 5 维度结构。结果显示具有良好的内部一致性（Cronbach's alpha 值在 0.71 到 0.83 之间，综合可靠性（CR）值高于 0.70），以及令人满意的收敛和区分效度（平均方差提取值（AVE）大于 0.50）。在验证性因素分析中，观察到了良好的模型拟合指标。IQEIC-P 具有良好的心理测量学特性，证明是评估专业人士视角下 EI 中心服务质量的有效工具。其效益将影响专业人士本身，并对这些中心所服务的家庭产生积极而直接的影响。
