Validation of the Mainland Chinese version of the Edinburgh Postnatal Depression Scale in Chengdu mothers

Background The Mainland Chinese version of the Edinburgh Postnatal Depression Scale (EPDS) has been validated among antenatal women, subsequent validation among postnatal women is necessary. Objectives This study investigated the prevalence of postnatal depression and the psychometric characteristics of the Mainland Chinese version of the EPDS among postnatal women. Design Two studies were used for validating the EPDS with specific aims. Study I established the psychometric properties of the EPDS by examining the convergent, discriminant and construct validity, internal consistency and stability of the scale. Study II established its sensitivity, specificity and the optimal cut-off score of the EPDS according the DSM-IV-TR criteria using the Structured Clinical Interview. Setting : Four regional public hospitals in Chengdu. Participants : A convenience sample was composed of 300 and 342 postnatal women in study I and II, respectively. Method A receiver operating characteristic (ROC) analysis was carried out to evaluate the global functioning of the scale. The Beck Depression Inventory (BDI), Dyadic Adjustment Scale (DAS) and standard SF-12 Health Survey (SF-12) were used to investigate the convergent, discriminant and construct validity. An exploratory factor analysis was used to investigate the structural validity of the scale. Confirmatory factor analysis (CFA) was tested the proposed factor module by Linear Structural Relations (LISREL). The Cronbach's alpha reliability coefficient, split-half reliability and test-retest reliability were used to examine the internal consistency and stability of the scale. Results The prevalence of postnatal depression was 4.7%. Structural validity revealed a three-factor structure for the EPDS and the CFA showed a good overall fit of this three-factor model. Convergent and construct validity was supported and discriminant validity suggested that the EPDS successfully discriminated among the nondepressed, mildly and clinically depressed groups. The area under curve (AUC) was 89.6% and the logistic estimate for the threshold score was 10.5 (sensitivity, 81.25%; specificity, 80.67%) for clinical depression. The split-half reliability of the EPDS was 0.74, Cronbach's alpha was 0.78 and test-retest reliability was 0.90. Conclusions Our data confirm the validity of the Mainland Chinese version of EPDS in identifying postnatal depression among postnatal women in Chengdu by using >10 cut-off point. Because of its brevity and acceptability, it is recommended that the EPDS be used in routine postnatal screening.

Study on the current situation of work values of contract nurses and the related factors

Objective To understand the current situation of work values and the needs of contract nurses, in order to provide the evidence of effective nursing human resources management. Methods 979 contract nurses in 7 3-Class general hospitals in Chengdu were surveyed by using Work Value Questionnaires. Results The top 3 dimensions of work values of contract nurses were relationship, achievement and economic rewards. Score of the dimension of economic rewards had significant difference among the nurses with different ages (P=0.004). Score of the dimension of social communications had significant difference among the nurses with different marriage status (P=0.005). Contract nurses with different work experiences gave different scores to economic rewards, social communications and security (P<0.01). Score of the dimension of intellectual stimulation had significant difference among the nurses with different professional titles (P=0.030). Conclusions Relationship, personal achievement and economic reward play important roles in the value system of contract nurses. Age, marriage status, work experiences and professional titles have influence on work value of contract nurses. Key words: Questionnaires; Contract nurses; Work values

Psychometric evaluation of the Mainland Chinese version of the Edinburgh Postnatal Depression Scale

Background The Edinburgh Postnatal Depression Scale (EPDS) has been validated in many countries, but not in Mainland China. Objectives This study investigated the reliability and validity of the Mainland Chinese version of the EPDS. Design A three-stage design was used for this study. Stage I consisted of a multi-stepped process of forward and backward translation, using a panel of six experts to test content validity. Stage II established the psychometric properties of the EPDS by examining the convergent, discriminant and construct validity, internal consistency and stability of the scale. Stage III established its sensitivity, specificity and the optimal cutoff score of the EPDS according the DSM-IV-TR criteria using the Structured Clinical Interview. Setting Three regional public hospitals in Chengdu. Participants A convenience sample was composed of 312 and 451 pregnant women at 28–36 weeks’ gestation. Method Translation and back-translation of the original English instrument and content validation by an expert panel. Receiver operating characteristic (ROC) analysis was carried out to evaluate the global functioning of the scale. The Beck Depression Inventory (BDI), Dyadic Adjustment Scale (DAS) and standard SF-12 Health Survey (SF-12) were used to investigate the convergent, discriminant and construct validity. The Cronbach's alpha reliability coefficient, split-half reliability and test–retest reliability were used to examine the internal consistency and stability of the scale. Results The translation process was rigorously conducted to ensure that equivalence was established. Content validity was confirmed by a satisfactory level of agreement with a content validity index (CVI) of 0.93. The area under curve (AUC) was 85.6% and the logistic estimate for the threshold score was 9.5 (sensitivity, 80.0%; specificity, 83.03%) for clinical depression. Convergent and construct validity was supported and discriminant validity suggested that the EPDS successfully discriminated among the non-depressed, mildly and clinically depressed groups. The split-half reliability of the EPDS was 0.76, Cronbach's alpha was 0.79 and test–retest reliability was 0.85. Conclusions Based on the results of this psychometric testing, the Mainland Chinese version of the EPDS is considered ready for use in the routine screening of pregnant women. It is hoped that with this type of cross-cultural information, the universality of the constructs of the instrument can be reliably demonstrated.

Food groups and risk of forearm fractures in postmenopausal women in Chengdu, China

Background Forearm fractures are a major cause of disability in postmenopausal women. However, no prior report on the relationship of dietary patterns and forearm fracture in mainland China is available and the results from Western studies may not be applicable to the Chinese population.Objective To determine whether food groups are associated with the risk of forearm fracture among postmenopausal women in China.Design Case–control study.Methods Cases were 209 postmenopausal women aged 50–70 years with new forearm fractures, identified in hospitals in Chengdu. Controls were age- and district-matched subjects randomly selected from the community of Chengdu. Dietary habits and food group intake were measured by a structured food frequency questionnaire.Results The dietary pattern in Chinese postmenopausal women was of high intakes of cereals, vegetables, fruits, beans or bean products, but lower intakes of meat and milk. The estimated odds ratios (95% confidence intervals) for forearm fracture were 0.53 (0.42–0.67) for each quintile increase in vegetable intake, 0.73 (0.59–0.92) for each quintile increase in cereal intake, and 0.26 (0.14–0.48) in subjects who met World Health Organization (WHO) dietary recommendations for vegetables and fruits.Conclusions This is the first report indicating that the levels of vegetable and cereal intake, and that meeting WHO recommendations for vegetable and fruit intake, are associated with a decrease in the risk of forearm fractures in Chinese postmenopausal women.

Aanlysis and strategies of sources of stress of nurses in cardiovascular department

Objective To analyze the main causes of sources of stress for nurses in cardiovascular department. Methods We selected 110 nurses from three class-one hospitals in Chengdu and divided them into the nurses in cardiovascular department (the research group) and nurses in other departments (the control group). We compared the two groups in the following aspects: family, society, interpersonal relationship, work nature and work strength, continuing education and professional demand. In view of the high spirit stress existed in nurses in cardiovascular department, some corresponding stress-relief strategies were adopted. Results Two groups were statistically different in social, interpersonal relationship, work nature and work strength, continuing education and professional demand. While in the aspect of family, no difference was seen. Conclusions nurses in cardiovascular department had high spirit stress in social, interpersonal relationship, work nature and work strength, continuing education and professional demand. To analyze sources of stress and stress-relief strategy for them could improve physical and psychological health of them and thus enhance nursing quality. Key words: Nurses in cardiovascular department; Source of stress; Physical and psychological health

Diet, activity, and other lifestyle risk factors for forearm fracture in postmenopausal women in China: a case-control study

Forearm fractures are a major cause of disability in postmenopausal women, but the risk factors have not been previously studied in China and the results from Western studies may not be applicable to the Chinese population. The aim of this study was to determine whether calcium intake, activity level, lifestyle, and other factors are associated with risk of forearm fracture among Chinese postmenopausal women. In this case-control study, the authors used a structured questionnaire to assess potential risk factors in 209 postmenopausal women 50 to 70 years old with new forearm fractures identified in eight hospitals in Chengdu and in age and location of residence-matched control subjects randomly selected from the community. Adjusted odds ratios (95% CIs) were as follows: each quintile increase in current energy intake 0.46 (0.36, 0.60); fifth quintile energy-adjusted current calcium intake versus lowest quintile, 0.17 (0.06, 0.47); eating bean products when 30 to 49 years old, 0.15 (0.05, 0.47); eating meat, 0.13 (0.02, 0.74) and eating pork ribs, 0.37 (0.17, 0.83) when 16 to 29 years old; greater past activity, 0.78 (0.68, 0.89) and present activity, 0.84 (0.74-0.96); greater height (per centimeter), 1.12 (1.06, 1.20); each year irregular menses before menopause, 1.25 (1.04, 1.49); each floor of residence, 1.71 (1.38, 2.12); and prior fracture in first- or second-degree relatives, 2.74 (1.08, 6.92). Some risk factors for forearm fractures were similar to those described in white women, whereas others were specific to this ethnic setting, and would need to be considered in future preventive programs.
