Individuals suffering from major depressive disorder (MDD) often report workplace-related stress as the major cause of their disorder. Accordingly, workplace-related stress was established as a fifth psychosocial problem area of Interpersonal Psychotherapy (workplace-related Interpersonal Psychotherapy, W-IPT). The aim of the study was to investigate the influence of W-IPT on depressive symptoms and on workplace-related issues in individuals with MDD compared to a treatment-as-usual (TAU) condition.
A total of 27 individuals with MDD (mean age = 43 years, 48% males) were randomly assigned either to eight weekly group sessions of W-IPT or to the TAU condition. At baseline, 8 weeks later at the end of the intervention, and 20 weeks later at follow-up, the Hamilton Rating Scale for Depression was conducted. In addition, the participants completed the Beck Depression Inventory, the Work Ability Index (WAI), the Return to Work Attitude (RTW-SE), and the Insomnia Severity Index (ISI).
Symptoms of depression in experts' ratings as well as in self-rated ratings decreased over time, but more so in the W-IPT condition compared to the TAU condition [experts rating: large effect size ( = 1.25) and self-assessment: large effect sizes ( = 0.94)]. The subjective ability to work (WAI) [medium effect size ( = 0.68)], self-efficacy to returning to work RTW-SE [medium effect size ( = 0.57)], and subjective symptoms of insomnia (ISI) [large effect size ( = 1.15)] increased over time, but again more so in the W-IPT condition compared to the TAU condition. The effects of the intervention remained stable from the end of the intervention to follow-up.
The pattern of results of this pilot study suggests that a newly established fifth IPT focus on workplace-related stress appeared to be particularly efficient in individuals with MDD due to work-related stress in reducing depressive symptoms and reducing sleep complaints as well as in improving occupational outcomes.
患有重度抑郁症（MDD）的个体常称与工作场所相关的压力是其患病的主要原因。因此，与工作场所相关的压力被确立为人际心理治疗（与工作场所相关的人际心理治疗，W-IPT）的第五个社会心理问题领域。本研究的目的是调查与常规治疗（TAU）相比，W-IPT对患有MDD的个体的抑郁症状及与工作场所相关问题的影响。
共有27名患有MDD的个体（平均年龄 = 43岁，48%为男性）被随机分配到接受为期八周的W-IPT小组治疗或TAU治疗组。在基线、干预结束8周后以及随访20周后，进行汉密尔顿抑郁评定量表评估。此外，参与者还完成了贝克抑郁量表、工作能力指数（WAI）、重返工作态度量表（RTW-SE）和失眠严重程度指数（ISI）。
专家评定以及自评中的抑郁症状随时间推移而减轻，但与TAU治疗组相比，W-IPT治疗组的减轻程度更大[专家评定：大效应量（ = 1.25），自评：大效应量（ = 0.94）]。主观工作能力（WAI）[中等效应量（ = 0.68）]、重返工作的自我效能感RTW-SE[中等效应量（ = 0.57）]和失眠主观症状（ISI）[大效应量（ = 1.15）]随时间推移而增加，但同样与TAU治疗组相比，W-IPT治疗组的增加幅度更大。从干预结束到随访，干预效果保持稳定。
这项初步研究的结果模式表明，新确立的人际心理治疗的第五个重点——关注与工作场所相关的压力，对于因工作相关压力而患有MDD的个体，在减轻抑郁症状、减少睡眠问题以及改善职业结果方面似乎特别有效。
