背景资料：抑郁、焦虑和积极展望量表（DAPOS）旨在测量疼痛人群的情绪，而不受躯体项目的污染。目的：本研究检查了疼痛患者的反应性、内部一致性和结构效度。方法：由慢性疼痛患者（其中大多数患有背痛）完成多学科康复干预前后的问卷调查。结果：与各种测量（SF-36;疼痛灾难化量表; Zung抑郁）相比，DAPOS显示出极好的内部一致性（N = 222，抑郁子量表的Cronbach α = 0.86，焦虑子量表的Cronbach α = 0.90，积极展望子量表的Cronbach α = 0.74）和结构效度（N = 82）。反应性是可以接受的（范围在0.5和0.7之间，治疗后评分的平均变化与基线时患者的变异性，以及标准化反应平均值），尽管远低于Zung抑郁量表。然而，没有躯体项目的再分析呈现的Zung反应不足，这表明在这一措施上的变化几乎完全是由于在躯体症状的变化，而不改变mood.Conclusions：DAPOS的反应性应重新评估明确针对情绪变化的治疗。DAPOS量表显示了可接受的临床和心理测量特性，并增加了积极前景的测量，以创建疼痛患者情绪的更平衡指示。
Background: The Depression, Anxiety, and Positive Outlook Scale (DAPOS) was designed to measure mood in pain populations without contamination from somatic items.Aims: The current study examined responsiveness, internal consistency, and construct validity in pain patients.Method: A questionnaire survey before and after a multi-disciplinary rehabilitation intervention was completed by chronic pain patients, the majority of whom had back pain.Results: The DAPOS showed excellent internal consistency (N = 222, Cronbach alpha = 0.86 for the Depression subscale, 0.90 for the Anxiety subscale, and 0.74 for the Positive Outlook subscale) and construct validity (N = 82) in comparison with a variety of measures (SF-36; Pain Catastrophizing Scale; Zung Depression). Responsiveness was acceptable (ranging between 0.5 and 0.7, for both the mean change in score after treatment to the variability in patients at baseline, and the standardized response mean), although considerably lower than the Zung Depression Inventory. However, reanalysis without somatic items rendered the responsiveness of the Zung inadequate, indicating that change on this measure was due almost entirely to change in somatic symptoms without change in mood.Conclusions: Responsiveness of the DAPOS should be reassessed in treatment targeting mood change explicitly. The DAPOS scales show acceptable clinimetric and psychometric properties, and add a measurement of positive outlook to create a more balanced indication of mood in pain patients.
