“…Moreover, Karasek and Theorell (1990) suggest that apart from negative physical effects of job strain (e.g., elevated blood pressure), depression and loss of selfconfidence are possible consequences of high work demands in combination with restricted decision latitude. Several studies have mainly verified the predictive value of single dimensions of the Job ÁDemand ÁControl Model (JDC-Model, Karasek, 1979) for mental health problems (De Jonge, Dormann, Janssen, Dollard, Landeweerd, & Nijhuis, 2001;Mausner-Dorsch & Eaton, 2000;Niedhammer, Goldberg, Leclerc, Bugel, & David, 1998). According to the EffortÁRewardÁImbalance Model (Siegrist, 1995) low rewards, high overcommitment, and the imbalance of efforts and rewards at work must be considered as risk factors for mental ill-health (Larisch, Joksimovic, Knesebek, Starke, & Siegrist, 2003;Pikhart et al, 2004;Tsutsumi, Kayaba, Theorell, & Siegrist, 2001).…”
