ABSTRACT: OBJECTIVES: Chinese correctional officers (COs) consist of frontline COs in direct contact with the prisoners and non-frontline COs (including administrative staff and professionals). Male COs compose the majority of Chinese COs, especially for frontline COs. Although they are quite susceptible to depressive symptoms due to highly risky and stressful working environment, few studies focus on this issue. This study aimed to evaluate the prevalence of depressive symptoms and to explore its associated factors among Chinese male frontline and non-frontline COs. METHODS: This cross-sectional study was performed during the period of March/April 2011. The study population comprised of 1,900 male COs in four male prisons in a province of northeast China. A questionnaire including the Center for Epidemiological Studies Depression Scale, demographic factors, work conditions, effort-reward imbalance questionnaire was distributed to these COs. A total of 1,494 effective respondents became our subjects (981 frontline COs and 513 non-frontline COs). Frontline and non-frontline COs were analyzed separately. RESULTS: Approximately 61.4 % of Chinese male COs had depressive symptoms (63.5 % in frontline COs and 57.3 % in non-frontline COs). Multivariate logistic analyses showed that effort-reward ratio, overcommitment, chronic disease, and threat perception were associated with depressive symptoms in frontline and non-frontline COs, whereas weekly work time had an effect only in frontline COs. CONCLUSIONS: Chinese male COs, especially frontline COs, might have high-level prevalence of depressive symptoms. Moreover, this study had identified important risk factors that might be important in planning strategies for prevention and intervention of depressive symptoms for Chinese male COs.

ABSTRACT: To establish a new method to estimate injury-tool by analyzing the components of left metal particles from hammers impact on pig skin and filter paper using scanning electron microscope and energy dispersive X-ray spectrometer (SEM-EDX).
The pig skin and filter paper were stricken by two steel hammers. The left metal particles were examined by SEM-EDX and the results were statistically analyzed by SPSS 13.0.
The characteristics of left particles showed stable by several impacts using one steel hammer. The left particles showed no statistical difference for impact on pig skin and filter paper. The left particles displayed a statistical difference using two hammer with different components.
SEM-EDX can be used to detect the left metal particles from the steel hammer and can provide a method for estimating injury-tool.

ABSTRACT: Although occupational stress is an identified predictor of depressive symptoms, the mechanism behind the association is not well understood. The purpose of this study was to examine how psychological capital (PsyCap), a positive psychological state, mediates the association between occupational stress and depressive symptoms among Chinese physicians.
A cross-sectional survey was conducted in Liaoning Province, China, during September-October 2010. Self-administered questionnaires including items on depressive symptoms assessed by the Center for Epidemiologic Studies Depression Scale, occupational stress assessed by the effort-reward imbalance scale and PsyCap estimated by a 24-item Psychological Capital Questionnaire, together with age, gender, marital status and education were distributed to 1300 physicians employed in large general hospitals. The final sample consisted of 998 participants. Asymptotic and resampling strategies were used to examine how PsyCap mediates the association between occupational stress and depressive symptoms.
Both the effort/reward ratio (ERR) and overcommitment were significantly associated with depressive symptoms among male and female physicians. There was a gender difference in the mediating role of PsyCap on the occupational stress-depressive symptoms association. For male physicians, PsyCap did not mediate the association between occupational stress and depressive symptoms. For female physicians, ERR and overcommitment were negatively associated with PsyCap, and PsyCap was negatively associated with depressive symptoms. As a result, PsyCap significantly mediated the associations of ERR and overcommitment with depressive symptoms. The proportion of PsyCap mediation was 19.07% for ERR, and 24.29% for overcommitment.
PsyCap could be a positive resource for combating depressive symptoms in Chinese physicians. In addition to reducing occupational stress, PsyCap development should be included in depression prevention and treatment strategies, especially for female physicians.

ABSTRACT: The aim of this study was to investigate the relation between work-family conflict and burnout, and the mediating role of psychological capital (PsyCap) in the relation between work-family conflict and burnout, among Chinese doctors.
This cross-sectional study was performed during the period of September/October 2010. A questionnaire that comprised work-family conflict assessed by the work-family conflict scale, PsyCap assessed by the PCQ-24 scale and burnout assessed by the Maslach Burnout Inventory-General Survey (MBI-GS), as well as age and gender, was distributed to 1,300 doctors in Liaoning Province, China. A total of 1,011 effective respondents became our final study subjects. Hierarchical linear regression analyses were performed by using SPSS 17.0 to explore the mediating role of PsyCap in the relation between work-family conflict and burnout.
Both work interfering family conflict (WIF) and family interfering work conflict (FIW) were positively related with emotional exhaustion and cynicism among both male and females doctors. However, WIF was positively related with professional efficacy only among male doctors, whereas FIW was negatively related with professional efficacy among both male and female doctors. PsyCap partially mediated the relation between WIF and professional efficacy among male doctors and partially mediated the relations of FIW with emotional exhaustion, cynicism and professional efficacy among female doctors.
Work-family conflict was associated with burnout among Chinese doctors. PsyCap was a mediator between work-family conflict and burnout. PsyCap might be a positive resource to reduce the negative effect of work-family conflict on burnout of doctors, especially female doctors, in China.
