Anhedonia is the core symptom of depression. Its presence has been linked to worsened prognosis. The Dimensional Anhedonia Rating Scale (DARS) is a scale measuring desire, motivation, effort and consummatory pleasure across different domains. The aim of this paper was to confirm factor structure, assess reliability and validity of the Polish adaptation of the DARS in a clinical sample of patients with mood disorders and healthy controls (HC).
The study sample included 161 participants aged 18-65 years - 34 HC, 72 patients with bipolar disorder and 55 with major depressive disorder (in depressive episode or remission). Reliability of the Polish adaptation of the DARS was assessed using Cronbach's α and the average inter-item correlation (AIC). Convergent and divergent validity was established by Pearson's correlations between the DARS and the Snaith-Hamilton Pleasure Scale (SHAPS), the Quick Inventory of Depressive Symptomatology- self-report (QIDS-SR), the Hospital Anxiety and Depression Scale (HADS). The structure of the scale was examined by factor analysis.
The factor structure was consistent with the original scale. Strong internal consistency for the DARS total score (Cronbach's α = 0.95) and all subscales (0.86-0.93) was observed. The DARS demonstrated good convergent (moderate to strong correlations with measures of anhedonia and depression) and divergent validity (weak correlations with anxiety level).
The Polish DARS demonstrated excellent internal consistency and very good validity. The scale is a valuable contribution to the psychometrics of anhedonia measures in patients with mood disorders.
快感缺失是抑郁症的核心症状。其存在与预后恶化有关。维度快感缺失评定量表（DARS）是一种测量不同领域欲望、动机、努力和满足性愉悦的量表。本文旨在确认波兰语版DARS在情绪障碍患者和健康对照（HC）临床样本中的因子结构，评估其信度和效度。
研究样本包括161名年龄在18 - 65岁的参与者——34名健康对照、72名双相情感障碍患者和55名重度抑郁症患者（处于抑郁发作期或缓解期）。使用克朗巴赫α系数和平均项间相关性（AIC）评估波兰语版DARS的信度。通过DARS与斯奈斯 - 汉密尔顿愉悦量表（SHAPS）、抑郁症状快速自评量表（QIDS - SR）、医院焦虑抑郁量表（HADS）之间的皮尔逊相关性来确定收敛效度和区分效度。通过因子分析检验量表的结构。
因子结构与原量表一致。观察到DARS总分（克朗巴赫α系数 = 0.95）和所有子量表（0.86 - 0.93）具有很强的内部一致性。DARS显示出良好的收敛效度（与快感缺失和抑郁测量指标呈中度至强相关性）和区分效度（与焦虑水平呈弱相关性）。
波兰语版DARS显示出优异的内部一致性和非常好的效度。该量表对情绪障碍患者快感缺失测量的心理测量学有重要贡献。
