[Relationship between job burnout and cognitive function and influencing factors of job burn out among medical staff].

OBJECTIVE: To explore the relationship between job burnout and cognitive function and the influencing factors of job burnout among medical staff. METHODS: Questionnaire survey was conducted for 197 medical workers in a grade-three general hospital in Beijing. Maslach Burnout Inventory-General Survey (MBI-GS) was carried out to assess the degree of job burnout among medical staff; Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was used to evaluate the overall cognitive function and cognitive situations of different dimensions. RESULTS: (1) There was a certain level of job burnout among medical staff, especially for the emotional exhaustion dimension (13.29 ± 7.67). (2) High level job burnout group (81.08 ± 12.34) scored lower on visual span than low level job burnout group (92.48 ± 19.62), P<0.05. Overall, job burnout had a negative influence on the general cognitive function (P<0.05). (3) The results of regression analysis indicated that, inefficacy was negatively correlated with age (r=-0.162, P<0.05). Job burnout was positively correlated with level of education (r=0.234, P<0.05) as well as exercise frequency (r=0.320, P< 0.001), and emotional exhaustion was correlated with overtime work (r=0.135, P<0.05); Level of job burnout stayed higher among doctors and nurses, compared with administration staff in hospitals (t=2.966, P<0.05). CONCLUSION: Job burnout of medical staff was relatively in high level; influenced by age, education level, overtime work, exercise frequency and occupational type, job burnout affected the visual span and general cognitive function.

Multiple cueing dissociates location- and feature-based repetition effects.

There is an extensive literature on the phenomenon of inhibition of return (IOR): When attention is drawn to a peripheral location and then removed, response time is delayed if a target appears in the previously inspected location. Recent research suggests that non-spatial attribute repetition (i.e., if a target shares a feature like color with the earlier, cueing, stimulus) can have a similar inhibitory effect, at least when the target appears in the previously cued location. What remains unknown is whether location- and feature-based inhibitory effects can be dissociated. In the present study, we used a multiple cueing approach to investigate the properties of location- and feature-based repetition effects. In two experiments (detection, and discrimination), location-based IOR was absent but feature-based inhibition was consistently observed. Thus, the present results indicate that feature- and location-based inhibitory effects are dissociable. The results also provide support for the view that the attentional consequences of multiple cues reflect the overall center of gravity of the cues. We suggest that the repetition costs associated with feature and location repetition may be best understood as a consequence of the pattern of activation for object files associated with the stimuli present in the displays.

Job Burnout, Mood State, and Cardiovascular Variable Changes of Doctors and Nurses in a Children's Hospital in China.

Aims. This study examines mood and cardiovascular variables related to job stress and burnout in hospital personnel. Main Methods. 400 nurses and physicians from a children's hospital in China were recruited. Participants completed job stress, burnout, and mood state questionnaires. Cardiovascular variables such as body mass index (BMI), triglyceride (TG), and high density lipoprotein (HDL) were measured. Key Findings. Job stress and burnout were significantly associated with mood state. Statistically significant correlations were found between triglyceride levels and job stress scores (r = 0.175, P < 0.01), BMI and job stress scores (r = 0.121, P < 0.05), and HDL levels and job stress scores (r = -0.117, P < 0.05). Significance. Mood state changes may be related to job stress and job burnout, in turn, associated with triglycerides and HDL levels. Public health implications and interventions are discussed.
