Parental Stress: Psychometric Evaluation of the German Version of the Parental Stress Scale in the General Population

Parental stress has negative impact on parents and their children. Parental stress may be of special interest for family and child well-being due to Covid-19 pandemic. A reliable and valid assessment of parental stress would be beneficial both in research and clinical practice. The Parental Stress Scale (PSS) is internationally well established as an economic and psychometric valid assessment. It consists of 18 items. The study evaluated the factor structure of the German version of the PSS in a general population (n=386 parents with children<16 years) for the first time. The sample was part of a representative sample (n=2519). The confirmatory factor analysis did not confirm internationally previously reported models. Eliminating one item, the explorative factor analysis suggested a two factor structure with the dimensions "lack of confident" and "worries and strain". Both subscales showed a good internal consistence (McDonalds omega >= 0,87). We observed correlations of the PSS-17 items with family dysfunction and elevated scores for depressive or anxiety symptoms, but not with sociodemographic factors. One conclusion is that the multidimensional construct of parental stress maybe is not comprehensively represented by the PSS. For the use in clinical practice and research this has to be taken into account. Albeit, the German version of the PSS is an economic, reliable and valid assessment.
