New research suggests that having job authority increases symptoms of depression among women, but decreases them among men.

"Women with job authority -- the ability to hire, fire, and influence pay -- have significantly more symptoms of depression than women without this power," Tetyana Pudrovska, lead author of the study, said in a statement. "In contrast, men with job authority have fewer symptoms of depression than men without such power."

For the study, researchers collected and analyzed data from more than 1,300 middle-aged men and 1,500 middle-aged women, who graduated from high schools in Wisconsin.

They found that women without job authority exhibit slightly more symptoms of depression on average than men without job authority. But among people with the ability to hire, fire, and influence pay, women typically exhibit many more symptoms of depression than men.

"What's striking is that women with job authority in our study are advantaged in terms of most characteristics that are strong predictors of positive mental health," Pudrovska said. "These women have more education, higher incomes, more prestigious occupations, and higher levels of job satisfaction and autonomy than women without job authority. Yet, they have worse mental health than lower-status women."

Previous studies suggest that women in authority positions deal with interpersonal tension, negative social interactions, negative stereotypes, prejudice, social isolation, as well as resistance from subordinates, colleagues, and superiors. All of this may increase the risk of women developing depression symptoms.

"Women in authority positions are viewed as lacking the assertiveness and confidence of strong leaders. But when these women display such characteristics, they are judged negatively for being unfeminine. This contributes to chronic stress." Pudrovska said.

On the other hand, Pudrovska said men in authority positions generally deal with fewer stressors because they do not have to overcome the resistance and negative stereotypes that women often face.

"Men in positions of authority are consistent with the expected status beliefs, and male leadership is accepted as normative and legitimate," she said. "This increases men's power and effectiveness as leaders and diminishes interpersonal conflict."

In terms of the study's policy implications, Pudrovska said the study indicates that "we need to address gender discrimination, hostility, and prejudice against women leaders to reduce the psychological costs and increase the psychological rewards of higher-status jobs for women."

The findings are detailed in the December issue of the Journal of Health and Social Behavior.
