老年人心理控制源对焦虑-抑郁的影响:无法忍受不确定性的中介作用

Impact of locus of control on anxiety and depression in aged adults: the mediating role of intolerance of uncertainty

目的探讨老年人的心理控制源与焦虑-抑郁水平的关系,着重探讨不确定忍耐力在其中的中介作用。方法采用心理控制源量表、焦虑-抑郁自评量表、短视不确定忍耐力量表对北京两所养老院的224名老年人进行调查,其中,心理控制源量表实际评估个体外控倾向。完成数据收集后,对数据进行描述性统计分析、F检验、相关分析、回归分析、路径分析。结果 (1)女性老年人整体心理健康水平差于男性,表现为女性老年人焦虑(F=15.82,P<0.01)、抑郁(F=15.20,P<0.01)水平更高。(2)心理控制源与老年人焦虑-抑郁显著相关,表现为外控倾向越高,焦虑(r=0.42,P<0.01)与抑郁(r=0.37,P<0.01)水平越高。(3)路径分析结果显示,无法忍受不确定性能够部分地中介控制源对老年人焦虑-抑郁情绪的影响。结论老年人的焦虑-抑郁情绪与其控制源有关,并且无法忍受不确定性能够中介控制源对焦虑-抑郁的影响。

Objective To investigate the relationship between locus of control and anxiety-depression in aged adults,mainly focusing on the mediating role of intolerance of uncertainty. Methods Two hundred and twenty-four aged adults completed the scales of intolerance of uncertainty,locus of control,and the self-rating depression and anxiety scales. The locus of control scale was used actually to assess one＇s tendency to be extra locus of control. The data were analyzed by descriptive statistics analysis,F test,correlation analysis,regression analysis and Pathway analysis. Results（1）The mental healthy level of male aged adults was better than that of female aged adults. Female aged adults were more anxious（ F = 15. 82,P〈0. 01） and depressed（ F = 15. 20,P〈0. 01） than male aged adults.（2）Locus of control were significantly positively correlated with symptoms of anxiety（ r = 0. 42,P〈0. 01） and depression（ r =0. 37,P〈0. 01）.（3） Pathway analysis showed that intolerance of uncertainty partially mediated the effect of locus of control on the symptoms of anxiety and depression. Conclusion The symptoms of anxiety and depression are related with locus of control in aged adults,and intolerance of uncertainty may mediate these effects.
