The modified Fresno test is a questionnaire developed to evaluate Evidence-Based Practice among physical therapists. A previous study has indicated that a shorter version with 9 items would be more appropriate for Brazilian physical therapists.
To test the measurement properties of the modified Fresno test - Brazilian-Portuguese short version.
To analyze the reliability of the modified Fresno test - Brazilian-Portuguese short version by two raters (intra and inter-rater) in a sample of 133 physical therapists. The intraclass correlation coefficient (ICC) and standard error of measurement (SEM) was used to assess the test-retest reliability. Internal consistency was tested using the Cronbach's alpha coefficient. An expert committee analyzed content validity using the content validity index (CVI). Confirmatory factor analysis (CFA) using the principal components method was used to assess construct validity. Responsiveness was estimated using effect size, and ceiling and floor effects were also investigated.
Inter-rater and intra-rater reliability were, respectively: ICC= 0.93 (95 % CI 0.91, 0.95); rater 1 - ICC= 0.95 (95 % CI 0.94, 0.97); rater 2 - ICC= 0.98 (95 % CI 0.98, 0.99). The agreement was very good (values ≤ 5 %). Internal consistency was good for most instrument items (≥ 0.80). The CVI showed agreement among the expert committee members (0.96). The Cronbach's alpha coefficients calculated for the corrected item total showed values greater than 0.40. In the CFA, the "model 2" showed acceptable indices (≥ 0.90). Responsiveness was classified as very small. No ceiling and floor effects.
The Fresno Modified Test - Brazilian-Portuguese short version has good to excellent reliability. CFA showed that the fit indices were adequate to be used in the population of interest.
改良的弗雷斯诺测试是一种用于评估物理治疗师循证实践的问卷。先前的研究表明，一个包含 9 个项目的更简短版本可能更适合巴西物理治疗师。
测试改良的弗雷斯诺测试-巴西葡萄牙语短版本的测量特性。
在 133 名物理治疗师的样本中，由两位评估者（内部和外部评估者）分析改良的弗雷斯诺测试-巴西葡萄牙语短版本的可靠性。使用组内相关系数（ICC）和测量标准误差（SEM）评估测试-重测信度。使用克朗巴赫的 alpha 系数测试内部一致性。内容效度由内容效度指数（CVI）进行专家委员会分析。使用主成分法进行验证性因子分析（CFA）评估结构效度。使用效应量估计反应性，并调查天花板和地板效应。
内部和外部评估者的可靠性分别为：ICC=0.93（95%CI 0.91，0.95）；评估者 1-ICC=0.95（95%CI 0.94，0.97）；评估者 2-ICC=0.98（95%CI 0.98，0.99）。一致性非常好（值≤5%）。大多数仪器项目的内部一致性良好（≥0.80）。CVI 显示专家委员会成员之间达成一致（0.96）。为校正项目总分计算的克朗巴赫的 alpha 系数显示值大于 0.40。在 CFA 中，“模型 2”显示出可接受的指标（≥0.90）。反应性被归类为非常小。无天花板和地板效应。
改良的弗雷斯诺测试-巴西葡萄牙语短版本具有良好至优秀的可靠性。CFA 显示，适合度指数足以在感兴趣的人群中使用。
