Validity And Reliability Of The Chinese Version Of Snaith-hamilton Pleasure Scale(SHAPS) In Assessment Of Patients With Depression

Background:Anhedonia is the most likely endophenotype concept of depression.Anhedonia has the vital significance for the treatment and prognosis of depression.But at present,domestic tool to evaluate the anhedonia in patients with depression is relatively lack.Objective:To test the validity and reliability of the Chinese version of the Snaith-Hamilton Pleasure Scale(SHAPS)in patients with depression.Methods:Totally 166 patients with major depression completed the Chinese version of SHAPS,Beck Depression Inventory(BDI-I)and Hamilton Depression Scale(HAMD-17).The validity was tested by using correlation analysis and exploratory factor analysis.The reliability was tested by using internal consistency coefficient and Pearson correlation analysis.Results:The ICCs between three different scale score were 0.90(P<0.001)and 0.91(P<0.001).Exploratory factor analysis identified 2 common factors,which explained 62.76%of total variance.The Cronbach coefficient of SHAPS was 0.94.The test-retest coefficient was 0.91(P<0.001).The intercorrelations of 14 items ranged from 0.30 to 0.93 and item-total correlations ranged from 0.61 to 0.79.Conclusion:The Chinese version of SHAPS has good validity and reliability,it could be used to assess anhedonia in Chinese patients with major depression.
