The Relationship Between Self-compassion And Anhedonia In Schizophrenia And Depression

Objective Schizophrenia and depression patients always show reduced mental health which characterized by a lot of negative feelings,decreased self-evaluation.As one of the objective criteria of mental health,self-compassion may be damaged.Although anhedonia is a common clinical symptom of schizophrenia and depression,few studies explore the relationship between self-compassion and anhedonia.Anhedonia looks the same on the surface in schizophrenia and depression,but it is essentially different in psychopathology.The difference may have influence on the relationship between self-compassion and anhedonia.So,the following objectives: first,we expect to know the level of self-compassion of schizophrenia and depression.Second,this study is to investigate the relationship between self-compassion and anhedonia.Third,this study is to explore the different influence of depressed symptoms on the relationship between self-compassion and anhedonia in schizophrenia and depression.Methods(1)subjects: 172 schizophrenic patients and 112 patients with depressive patients,176 healthy controls(HC).(2)All subjects were assessed with the Chinese Version of Revised Self-Compassion Scale(SCS-C),the Chinese Version of Revised Social Anhedonia Scale(RSAS-C),and the Chinese Version of Revised Physical Anhedonia Scale(RPAS-C).Schizophrenic patients also were assessed by the Beck Depression Inventory(BDI)and the Positive and Negative Syndrome Scale(PANSS),meanwhile,depressive patients also were rated with the BDI.Results(1)Depressive patients had lower total score of SCS-C,higher scores ofRPAS-C and RSAS-C when compared with the healthy subjects(all P<0.01).The SCS-C total score was significantly negatively correlated with RPAS-C score(r=-0.325,P<0.01)and RSAS-C score(r=-0.347,P<0.01)in depression.When the BDI score is regarded as a covariate,the relationship between self-compassion and anhedonia has no statistical significance in depression(r=-0.153,-0.174,P>0.05).(2)Schizophrenic patients had lower total score of SCS-C,higher scores of RPAS-C and RSAS-C when compared with the healthy subjects(all P<0.01).The SCS-C total score was significantly negatively correlated with RPAS-C score(r=-0.382,P<0.01)and RPAS-C score(r=-0.422,P<0.01)in schizophrenia.When the BDI score is regarded as a covariate,the relationship between self-compassion and anhedonia remains persistent(r=-0.258,-0.304,P<0.01).Conclusion Patients with schizophrenia and depression have self-compassive deficits,and depressive patients were worse than schizophrenia.All patients have physical anhedonia and social anhedonia,and depressive patients were more severe than schizophrenia.The lower self-compassion was,the higher anhedonia was in two groups.The relationship between self-compassion and anhedonia is independently of symptom in schizophrenia,however,the relationship between self-compassion and anhedonia in depression is affected by the depressed symptoms,suggesting there is different pathomechanism of the influence of self-compassion on anhedonia in two patients group.
