This study aimed to validate and explore the psychometric properties of the credibility/expectancy questionnaire (CEQ) for the Portuguese population in the context of routine practice. The sample includes 87 clients from a university psychotherapy clinic. All clients completed self-report measures to assess credibility and expectation (CEQ), as well as measures of general mental health, depressive symptoms and therapeutic alliance in session 1 and session 2. The exploratory analysis revealed the existence of two factors in CEQ for the Portuguese population, factor 1 credibility and factor 2 expectation. The measure demonstrated good internal consistency, test-retest reliability and good adjustment in the confirmatory analysis. In terms of convergent validity, no significant correlation was found between credibility and expectation and the therapeutic alliance. The results corroborate the CEQ psychometric qualities for the Portuguese population, also showing its applicability in a context of routine practice.
本研究旨在验证并探索可信度/期望问卷（CEQ）在葡萄牙人群常规实践背景下的心理测量特性。样本包括来自一所大学心理治疗诊所的87名来访者。所有来访者均完成了自我报告测量，以评估可信度和期望（CEQ），以及在第1次和第2次治疗时的一般心理健康、抑郁症状和治疗联盟测量。探索性分析揭示了葡萄牙人群CEQ中存在两个因素，因素1为可信度，因素2为期望。该测量在验证性分析中显示出良好的内部一致性、重测信度和良好的拟合度。在收敛效度方面，可信度和期望与治疗联盟之间未发现显著相关性。结果证实了CEQ在葡萄牙人群中的心理测量质量，也表明了其在常规实践背景下的适用性。
