[Effort-Reward Imbalance in Household and Family Work--Analysing the Psychometric Properties among Fathers of Underage Children].

Recently, the concept of effort-reward imbalance (ERI) developed by Siegrist had been applied to unpaid household and family work (ERI-HF). Evidence suggests that the imbalance between effort spent and reward received in family and domestic labor is associated with poor mental and physical health. However, so far, the adopted questionnaire ERI-HF was exclusively used among women in childcare responsibility. This paper reports on the application of the model to men in childcare responsibility using data from a clinical sample of fathers in rehabilitation clinics (N=415). Analogous to the original version, ERI-HF is divided into 2 components: (i) dysbalance of effort and reward, and (ii) overcommitment. For both components, confirmatory factor analyses revealed good to satisfactory properties. Overall, 13.4% of men in childcare responsibility showed a dysbalance between high effort and low reward of household and family work. High levels of effort were more frequently reported than high levels of low reward. With percentages ranging between 24.3 and 59.6%, a significant proportion of fathers reported difficulties to withdraw from household and family work obligations. Analyses of construct validity revealed significant associations between ERI and socio-demographic factors (number of children, employment status, single fatherhood, work-family-conflict) as well as subjective health. Taken together, our findings suggest that the instrument is applicable to men in childcare responsibility.
