We developed the Interpersonal Sensitivity/Privileged Self Scale (IPS) to measure personality traits related to “modern-type depression,” and assessed its validity and reliability through three surveys completed by 804 undergraduates. Factors for validity were examined by confirmatory factor analysis. As predicted, the scale comprised two superordinate factors: interpersonal sensitivity (IS) and privileged self (PS). Criterion-related validity for the IPS scale was assessed by examining its relationship with depressive symptoms and typus melancholicus, and by comparing subscale scores regarding depression types (i.e., melancholic, atypical). All subscale scores were positively correlated with depressive symptoms. Correlations between typus melancholicus and subscales showed that the interpersonal sensitivity subscale was positively correlated with typus melancholicus, while the privileged self subscale was not correlated. An analysis of variance revealed that the “self-righteousness” score was significantly higher for the atypical depression group compared to the melancholic depression group. The test-retest correlation indicated good test-retest reliability for all subscales. Overall, the findings indicated that the IPS has high validity and reliability.
我们编制了人际敏感性/特权自我量表（IPS）来测量与“现代型抑郁症”相关的人格特质，并通过804名本科生完成的三项调查评估了其效度和信度。通过验证性因素分析检验效度因素。正如预期的那样，该量表包含两个上位因素：人际敏感性（IS）和特权自我（PS）。通过检查IPS量表与抑郁症状和抑郁性抑郁症的关系，并比较抑郁类型（即抑郁性、非典型性）的子量表得分，评估了IPS量表的效标效度。所有子量表得分均与抑郁症状呈正相关。抑郁性抑郁症与子量表之间的相关性表明，人际敏感性子量表与抑郁性抑郁症呈正相关，而特权自我子量表则无相关性。方差分析显示，非典型抑郁症组的“自以为是”得分显著高于抑郁性抑郁症组。重测相关性表明所有子量表的重测信度良好。总体而言，研究结果表明IPS具有较高的效度和信度。
