Critiques of the validity of the DSM diagnostic criteria for depressive disorder argue that it fails to differentiate between abnormal sadness due to internal dysfunction or depression (sadness without an identifiable cause), and normal sadness (sadness with a clear cause).

A population survey was undertaken in adult education centres in Spain aiming to explore beliefs about depression and normal sadness. Two hypothetical case vignettes portrayed individuals experiencing deep sadness, both fulfilling criteria for major depressive disorder (DSM-IV), one with a clear cause, the other without an identifiable cause. Three hundred and forty-four (344) questionnaires were obtained (95% response rate).
Participants statistically significantly differentiated between the sadness-with-cause vignette, seen more frequently as a normal response, while the one without a cause was seen as pathological. Help-seeking behaviour recommendations followed this distinction: a medical option was statistically significantly more common when there was no cause for sadness. Socio-cultural variation in how people understand and deal with sadness was also found.
This study emphasizes the importance of taking into account the context in which depressive symptoms occur as it seems that the absence of an appropriate context is what makes people conceptualize them as abnormal. It also raises questions about the lack of face validity of the current diagnostic classification for depressive disorder that exclusively uses descriptive criteria.
对抑郁障碍的 DSM 诊断标准有效性的批评认为,它未能区分由于内部功能障碍或抑郁症引起的异常悲伤(无明确原因的悲伤)与正常悲伤(有明确原因的悲伤)。
在西班牙的成人教育中心进行了一项人群调查,旨在探讨对抑郁和正常悲伤的信念。两个假设的案例描述了经历深度悲伤的个体,均符合 DSM-IV 重度抑郁障碍的标准,一个有明确原因,另一个没有可识别的原因。共获得 344 份问卷(95%的回应率)。
参与者在有原因的悲伤案例与无原因的悲伤案例之间进行了统计学上的显著区分,前者更常被视为正常反应,而后者则被视为病理性的。寻求帮助的行为建议遵循这一区别:当悲伤没有原因时,选择医学方法的比例统计学上显著更高。还发现了人们理解和处理悲伤的社会文化差异。
本研究强调了考虑抑郁症状发生背景的重要性,因为似乎正是缺乏适当的背景使人们将其概念化为异常。它还提出了关于当前仅使用描述性标准的抑郁障碍诊断分类缺乏表面有效性的问题。
