领悟社会支持量表在50岁以上中老年群体的跨性别测量等值性

Gender measurement invariance of the Perceived Social Support Scale in people aged 50 years and older

目的检验领悟社会支持量表(PSSS)在50岁以上中老年人群体中的跨性别等值性。方法利用PSSS对北京、湖南和山东三地1013名社区中老年人(50~96岁)进行调查。随后考查PSSS在不同性别中老年人群体中的测量等值性。最后对男性和女性两组样本在PSSS总分和分量表上的得分进行差异性检验。结果问卷各步骤的测量等值性检验的结果均满足测量学要求(△CFI≥0.010,△TLI≥0.010 △RSMEA≤0.015),说明PSSS在不同性别的中老年人群体中的形态等值、弱等值、强等值和严格等值假设均成立。女性中老年人样本在家庭支持、朋友支持、其他人支持和领悟社会支持的总体水平上均高于男性(均P<0.05)。结论 PSSS在中老年人群中具备跨性别等值性,即不同性别中老年人群体的领悟社会支持水平能够通过PSSS得分差异来反映。

Objective To investigate gender measurement invariance of the Perceived Social Support Scale(PSSS)in people aged 50 years and older.Methods A total of 1013 adults(50-96 years old)in Beijing,Hunan and Shandong were tested by using PSSS.The measurement invariance of PSSS between middle-aged and elderly males and females was analyzed.Differences in PSSS total scores and subscale scores between males and females were examined.Results The equivalence test results of each item in the questionnaire met the requirements of the metrology(△CFI≥0.010,△TLI≥0.010,△RSMEA≤0.015),indicating that the hypotheses of morphological equivalence,weak equivalence,strong equivalence and strict equivalence of PSSS were all valid in the middle-aged and elderly population regardless of gender.In addition,middle-aged and elderly females had higher scores in family support,support from friends,support from other people and perceived social support than their male counterparts(P<0.05).Conclusions PSSS has cross-gender equivalence in middle-aged and elderly people.Thus,differences in PSSS can reflect the perceived social support level in middle-aged and elderly people of different genders.
