The strength of the therapeutic alliance is widely understood to impact treatment outcomes, however, the alliance-outcome relationship in teletherapy has remained relatively unexamined. The aim of this meta-analysis is to systematically summarize the relationship between therapeutic alliance and treatment outcomes in teletherapy with adult patients conducted via videoconferencing or telephone. We conducted a systematic search of the databases PsycINFO, PsycARTICLES, ProQuest Dissertation Databases, EMBASE, The Cochrane Library, MEDLINE, Google Scholar, and PubMed for studies published before June 26, 2023. We identified 31 studies with 34 independent samples (4862 participants). The average weighted effect size was 0.15, = .001, 95% CI [0.07, 0.24], = 34. Very few teletherapy treatment studies were identified that initially reported on alliance-outcome associations, underlining that this is an under-researched area. The association between alliance-teletherapy outcomes in this meta-analysis was small but significant, and somewhat weaker than the alliance-outcome associations reported for in-person treatments and other online interventions. This might indicate that there are other processes at play in teletherapy that explain variance of treatment outcomes, or that the therapist (and the relationship) has less influence on the treatment outcomes than in in-person therapy.

远程治疗中治疗联盟质量与治疗结果之间的关联：系统评价和荟萃分析


人们普遍认为治疗联盟的强度会影响治疗结果，然而，远程治疗中的联盟与结果之间的关系仍然相对未经检验。本荟萃分析的目的是系统地总结通过视频会议或电话对成年患者进行远程治疗时治疗联盟与治疗结果之间的关系。我们对数据库 PsycINFO、PsycARTICLES、ProQuest Dissertation Databases、EMBASE、The Cochrane Library、MEDLINE、Google Scholar 和 PubMed 进行了系统检索，查找 2023 年 6 月 26 日之前发表的研究。我们确定了 31 项研究，涉及 34 个独立样本（4862 名参与者） 。平均加权效应大小为 0.15, = .001, 95% CI [0.07, 0.24], = 34。很少有远程治疗研究最初报告了联盟-结果关联，强调这是一个研究不足的领域。在这项荟萃分析中，联盟与远程治疗结果之间的关联虽小，但意义重大，并且比面对面治疗和其他在线干预措施所报告的联盟与远程治疗结果之间的关联要弱一些。这可能表明远程治疗中还有其他过程在起作用，可以解释治疗结果的差异，或者治疗师（及其关系）对治疗结果的影响小于面对面治疗。
