Abstract
BackgroundThe evaluation of childhood trauma is essential for the treatment of schizophrenia. The short form of Childhood Trauma Questionnaire (CTQ-SF) is a widely used measure of the experience of childhood trauma in the general population. Nevertheless, data regarding the psychometric property of CTQ-SF for assessing childhood trauma of patients with schizophrenia are very limited.MethodsTwo hundred Chinese inpatients with schizophrenia completed the Chinese CTQ-SF, the Child Psychological Maltreatment Scale (CPMS), the Impact of Events Scale-Revised (IES-R), and the Dissociative Experiences Scale-II (DES-II). To assess test-retest reliability of the CTQ-SF, all patients completed the CTQ-SF again two weeks later. Concurrent and convergent validity was assessed by analyzing Pearson bivariate correlation coefficients between CTQ-SF and CPMS, IES-R, and DES-II.ResultsThe Cronbach’s α coefficient of the Chinese CTQ-SF was 0.81, and the two-week re-test reliability was 0.81 (P<0.01). The criterion-related validity coefficients of CTQ-SF with the CMPS, IES-R and DES-II were 0.61, 0.41, and 0.51, respectively.ConclusionThe Chinese CTQ-SF has satisfactory psychometric properties to measure childhood abuse or neglect in Chinese inpatients with schizophrenia.
Highlights
Concurrent and convergent validity was assessed by analyzing Pearson bivariate correlation coefficients between CTQ-SF and Child Psychological Maltreatment Scale (CPMS), IES-R, and Dissociative Experiences Scale-II (DES-II)
This study explored whether the Chinese version of the CTQ-SF is applicable for the assessment of childhood trauma in Chinese inpatients with schizophrenia
Patients were considered qualified for the study if they 1) met the diagnosis of schizophrenia according to the ICD-10 as assessed by experienced psychiatrists; 2) were clinically stable; 3) aged between18 and 40 years; and 4) had an educational attainment of at least primary school
Summary
The evaluation of childhood trauma is essential for the treatment of schizophrenia. The short form of Childhood Trauma Questionnaire (CTQ-SF) is a widely used measure of the experience of childhood trauma in the general population. Data regarding the psychometric property of CTQ-SF for assessing childhood trauma of patients with schizophrenia are very limited
