Abstract

Objective: The Relational Depth Frequency Scale (RDFS) is a 6-item measure to assess the impact of relational depth experiences on psychotherapeutic outcomes. To date, the RDFS has only been validated in online samples of clinical and non-clinical individuals. This study aimed to examine the psychometric properties of the RDFS in clinical dyads of clients and psychotherapists.

Method: A total of 86 psychotherapy dyads—86 psychotherapists (18 male, 68 female, mean age = 44.34) and 86 clients (17 male, 69 female, mean age = 34.22)—completed the RDFS, and the Scale to Assess the Psychotherapeutic Relationship (STAR), mid-psychotherapy.

Results: CFA showed acceptable fit statistics for a one-factor model. The partial measurement invariance across both partners of the psychotherapeutic dyad was positively verified. The RDFS had good internal consistency for psychotherapists and clients (α = .90 and .81, respectively). Actor-partner interdependence model confirmed moderate to high levels of convergent validity against the STAR. Relational depth in both partners was predicted by their own perceptions of the quality of the psychotherapeutic relationship. Psychotherapist frequency of relational depth was also related to client perceptions of the psychotherapeutic relationship.

Conclusion: The RDFS is a promising tool measuring relational depth both from psychotherapist and client perspectives.

摘要

目的：关系深度频率量表 (RDFS) 是一项 6 项测量，用于评估关系深度体验对心理治疗结果的影响。迄今为止，RDFS 仅在临床和非临床个体的在线样本中得到验证。本研究旨在检查 RDFS 在客户和心理治疗师的临床二元组中的心理测量特性。

方法：共有 86 名心理治疗师——86 名心理治疗师（18 名男性，68 名女性，平均年龄 = 44.34）和 86 名来访者（17 名男性，69 名女性，平均年龄 = 34.22）——完成了 RDFS 和心理治疗评估量表关系（STAR），中期心理治疗。

结果：对于单因素模型，CFA 显示出可接受的拟合统计量。对心理治疗二元组双方的部分测量不变性进行了积极验证。RDFS 对心理治疗师和来访者具有良好的内部一致性（分别为α  = .90 和 .81）。参与者-合作伙伴相互依赖模型证实了针对 STAR 的中度至高度收敛效度。双方的关系深度是由他们自己对心理治疗关系质量的看法来预测的。心理治疗师的关系深度频率也与来访者对心理治疗关系的看法有关。

结论：从心理治疗师和客户的角度来看，RDFS 是一种很有前途的测量关系深度的工具。
