Perceived injustice has been associated with problematic recovery outcomes in individuals with debilitating health conditions. However, the relation between perceived injustice and recovery outcomes has not been previously examined in individuals with debilitating mental health conditions. The present study examined the relation between perceived injustice and symptom severity in individuals undergoing treatment for Major Depressive Disorder (MDD).
The study sample consisted of 253 work-disabled individuals with MDD who were referred to an occupational rehabilitation service. Participants completed measures of depressive symptom severity, perceived injustice, catastrophic thinking, pain and occupational disability at three time-points (pre-, mid- and post-treatment) during a 10-week behavioural activation intervention.
Regression analysis on baseline data revealed that perceived injustice contributed significant variance to the prediction of depressive symptom severity, beyond the variance accounted for by time since diagnosis, pain severity and catastrophic thinking. Prospective analyses revealed that early treatment reductions in perceived injustice predicted late treatment reductions in depressive symptom severity.
The study sample consisted of work-disabled individuals with MDD who had been referred to an occupational rehabilitation service. This selection bias has implications for the generalizability of findings.
The findings suggest that perceived injustice is a determinant of symptom severity in individuals with MDD. The inclusion of techniques designed to reduce perceived injustice might augment positive treatment outcomes for individuals receiving treatment for MDD.
在患有身体虚弱疾病的个体中，感知到的不公正与不良的康复结果有关。然而，在患有严重精神健康状况的个体中，感知到的不公正与康复结果之间的关系尚未得到检验。本研究探讨了在接受重度抑郁症（MDD）治疗的个体中，感知到的不公正与症状严重程度之间的关系。
研究样本包括 253 名因 MDD 而丧失工作能力的个体，他们被转介到职业康复服务机构。参与者在 10 周行为激活干预治疗的三个时间点（治疗前、治疗中和治疗后）完成了抑郁症状严重程度、感知不公正、灾难性思维、疼痛和职业残疾的测量。
基线数据的回归分析显示，感知不公正除了与诊断后时间、疼痛严重程度和灾难性思维有关的方差外，还对抑郁症状严重程度的预测有显著贡献。前瞻性分析显示，早期治疗中感知不公正的减少预测了晚期治疗中抑郁症状严重程度的减少。
研究样本包括因 MDD 而丧失工作能力的个体，他们已被转介到职业康复服务机构。这种选择偏差对研究结果的普遍性有影响。
研究结果表明，感知到的不公正程度是 MDD 患者症状严重程度的决定因素。纳入旨在减少感知不公正的技术可能会增强接受 MDD 治疗的个体的积极治疗结果。
