Abstract

We verified the need for instruments that could assess the perceptions of patients, therapists, and psychotherapy supervisors about online Psychotherapy. Objectives: to Build a scale of advantages and disadvantages of online psychotherapy. Method: A pilot cross-sectional multicenter sample collected from 2020 to 2021 of 129 patients, 20 therapists, and 35 supervisors. We used several analyses. The final scale contained 22 items divided into two domains: advantages and disadvantages. Results: Cronbach's alpha showed good internal consistency (0.88 and 0.85). The scale showed discriminative ability. Convergent validity showed significant correlations between WAI-SR domains (p 〈0,001). The scale showed a good data fit in the confirmatory factor analysis (X² = 255,859; DF = 197; p = .003; CFI = 0.95; RMSEA = 0.047; GFI = 0.84 TLI = 0.94). Conclusion: This pilot study showed that the instrument proved preliminary good psychometric properties but needs to be evaluated in a larger sample.

在线心理治疗利弊工具的心理计量特性：多中心试点研究的初步结果。

我们验证了对可评估患者、治疗师和心理治疗督导对在线心理治疗看法的工具的需求。目标：建立在线心理治疗利弊量表：从 2020 年到 2021 年，我们对 129 名患者、20 名治疗师和 35 名督导进行了试点横断面多中心抽样调查。我们采用了多种分析方法。最终量表包含 22 个项目，分为两个领域：优势和劣势：Cronbach's alpha 显示了良好的内部一致性（0.88 和 0.85）。该量表具有区分能力。收敛效度显示 WAI-SR 各领域之间存在显著相关（p 〈0,001）。量表在确认性因素分析中显示出良好的数据拟合（X2 = 255,859; DF = 197; p = .003; CFI = 0.95; RMSEA = 0.047; GFI = 0.84 TLI = 0.94）：这项试点研究表明，该工具具有初步的良好心理测量特性，但还需要在更大的样本中进行评估。
