冗思反应量表简版在抑郁症状阴性和阳性大学生人群中的测量等值性

Measurement Equivalence of the 10-item Ruminative Response Scale Across Groups with Screen-negative or Screen-positive Depressive Symptoms

目的:检验冗思反应量表简版(10-item Ruminative Response Scale,RRS-10)在抑郁症状阴性和阳性大学生人群中的测量等值性,并探讨抑郁与冗思的关系。方法:7842名中国在校大学生完成了RRS-10和流调中心抑郁量表(Center for Epidemiological Studies Depression Scale,CES-D)。根据CES-D的划界分,有7347名大学生为抑郁阴性组,495名为抑郁阳性组。结果:单组验证性因素分析结果表明RRS-10的两因子结构在抑郁症状阳性组和阴性组样本中均拟合良好。多群组验证性因素分析的结果表明RRS-10在抑郁症状阳性组和阴性组两样本间达到部分等值。独立样本t检验结果表明抑郁症状阳性组在冗思总体水平、沉思因子及反思因子上的得分显著高于抑郁阴性组。结论:RRS-10在抑郁阳性组和阴性组两样本间具有部分等值性。抑郁阳性个体的冗思水平显著高于抑郁阴性个体。

Objective： This study aimed to test the measurement equivalence of the Chinese version of the 10-item Ru- minative Response Scale（RRS-10） across groups with screen-negative or screen-positive depressive symptoms in a large Chinese undergraduate sample. Methods： A total of 7,842 university students finished the RRS-10 and the Center for Epi- demiological Studies Depression Scale（CES-D）. According to the cut-off score of CES-D, 7,347 subjects were classified as group with screen-negative depressive symptoms, and 495 subjects were classified as screen-positive group with depres- sive symptoms, respectively. Results： A two-factor model of RRS-10 fit the data reasonably both in group with screen-neg- ative or screen-positive depressive symptoms. And the RRS- 10 was equivalent across these two groups. Besides, group with screen-positive depressive symptoms had higher rumination scores than group with screen-negative depressive symp- toms. Conclusion： The Chinese version of the RRS-10 had measurement equivalence across groups with screen-negative or screen-positive depressive symptoms in Chinese undergraduates. In addition, individuals with screen-positive depres- sive symptoms show more rumination than those with screen-negative depressive symptoms.
