Effect of occupational commitment on job burnout of traditional Chinese medicine doctors / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the status of job burnout in traditional Chinese medicine (TCM) doctors and explore the effect of occupational commitment on job burnout.</p><p><b>METHODS</b>A test of occupational commitment and job burnout was carried out in 507 TCM doctors with occupational commitment questionnaire and Maslach Burnout Inventory-Human Services Survey (MBI-HSS).</p><p><b>RESULTS</b>The age group of < 30 years scored lowest (2.352 +/- 0.660) in personal accomplishment compared with 30 years old group and 40 years old group [(2.136 +/- 0.704) and (2.127 +/- 0.628) respectively] (P < 0.01). The score of emotional exhaustion and depersonalization increased with educational levels. There was significantly negative correlation between job burnout and occupational commitment (P < 0.01). Occupational commitment had significant effect on job burnout (P < 0.01). Occupational trouble commitment was a major predictor for emotional exhaustion (P < 0.01). Professional self-efficacy commitment was a major predictor for depersonalization (P < 0.01). Affective commitment was a major predictor for personal accomplishment (P < 0.01).</p><p><b>CONCLUSION</b>Occupational commitment is a good predictor for job burnout. Improving occupational commitment is an important measure to prevent job burnout.</p>

Association between the functional monoamine oxidase A gene polymorphism and aggressively driving behavior / 中华预防医学杂志

<p><b>OBJECTIVE</b>This study is purposed to explore the relationship between aggressively driving behavior and functional polymorphism in the promoter region of the monoamine oxidase-A (MAOA) gene.</p><p><b>METHODS</b>A total of 348 automobile drivers were investigated with Deffenbacher's driver anger scale, driving vengeance questionnaire (DVQ) and driver aggression behavior questionnaire. Eighty-eight drivers were selected as more, medium and less aggressive group, each. Polymerase chain reaction (PCR) and 2.5% agarose gel electrophoresisi were adopted to detect the polymorphism of functional 30 bp-uVNTR in the promoter region of the X-chromosomal MAOA gene and their frequencies of varied genotypes were estimated.</p><p><b>RESULTS</b>Two alleles with 3 and 4 repeats of 30 bp-uVNTR were detected in the drivers. Among the more aggressive group, number of the allele with 3 repeats of 30 bp-uVNTR (63/88) was significantly more than that with 4 repeats (25/88) (chi(2) = 10.21, P < 0.01), and number of the allele with 4 repeats of 30 bp-uVNTR was more in the less aggressive group, indicating that persons with allele of 3 repeats of 30 bp VNTR were more aggressive in their driving than those with 4 repeats.</p><p><b>CONCLUSIONS</b>Aggressively driving behavior in drivers possibly related to their functional MAOA-uVNTR polymorphism. Effect of the gene on aggressively driving behavior should be further studied.</p>

Human factors of drivers and traffic accidents / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To find out the relationship of traffic accidents with life events, driving stress, aggressive driving, etc.</p><p><b>METHODS</b>A total of 905 automobile drivers were investigated with life events scale (LES), general driver stress questionnaire, driver behavior inventory and accidents experience, etc.</p><p><b>RESULTS</b>The scores of life events, driving stress, and aggressive driving in accident drivers (21.79 +/- 14.10, 23.81 +/- 11.86, 9.42 +/- 8.25 respectively) were higher than those in nonaccident drivers (16.82 +/- 8.45, 20.09 +/- 10.63, 5.66 +/- 7.54) (P < 0.01). The number of vehicle accidents was significantly correlated with the scores of LES, driving stress, driver's aggressive behavior, drowsy driving, weekly time of driving, drinking index (P < 0.05). A logistic analysis (Forward:LR) showed that the driving hour, drowsy driving, aggressive driving, and drinking index were closely related with traffic accidents (P < 0.01).</p><p><b>CONCLUSION</b>Life events, driving stress and aggressive driving of the drivers are important factors related to traffic accidents.</p>
