The aim of this study was to examine and compare the treatment effects of counselling in clients’ primary language and counselling with an interpreter. National Institute for Health and Care Excellence (NICE) guidance indicated that interpreters should be used when working with individuals whose primary language is not English. Following a pre-test post-test non-equivalent groups design, clients (N = 133) received counselling in their primary language or through an interpreter. Measures of depression (Patient Health Questionnaire; PHQ-9) and anxiety (Generalised Anxiety Disorder Scale; GAD-7) were completed pre- and post-treatment to examine treatment outcomes. Data were analyzed using a 2 (condition) x 2 (time) mixed design Analysis of Variance (ANOVA). There was no significant difference in treatment outcome between counselling in client’s primary language and interpreter facilitated counselling. Client satisfaction was rated high in both groups, and no significant difference was found. The findings suggest that interpreters can be used effectively when offering counselling to clients whose primary language is not English. Due to service provision, clients were not randomly allocated, and no control group was used.

本研究的目的是检查和比较以客户的主要语言进行咨询和使用口译员进行咨询的治疗效果。国家健康与护理卓越研究所 (NICE) 指南指出，在与主要语言不是英语的个人一起工作时应使用口译员。按照前测后测非等效组设计，客户（N = 133) 以他们的主要语言或通过翻译接受咨询。抑郁症（患者健康问卷；PHQ-9）和焦虑（广义焦虑症量表；GAD-7）的测量在治疗前和治疗后完成，以检查治疗结果。使用 2（条件）x 2（时间）混合设计方差分析 (ANOVA) 分析数据。以客户的主要语言进行咨询和口译促进咨询之间的治疗结果没有显着差异。两组的客户满意度都很高，并且没有发现显着差异。调查结果表明，在为主要语言不是英语的客户提供咨询时，可以有效地使用口译员。由于提供服务，没有随机分配客户，也没有使用对照组。
