Impact of pediatric cancer on parents' relationships.

Purpose: Cancer in children leads to changes in family life, which can also affect the stability and quality of the parents' relationships. Studies show that parents' educational level, duration of partnership until diagnosis, child's cancer, and grandparents' relationship stability may influence parental partnership. The aim of this study was to investigate the influence of childhood cancer on the stability and quality of parental relationships in Germany.

Methods: N = 74 parents of children with cancer aged 28-65 years (M = 41.9, SD = 7.6) completed questions on the stability and quality of their partnership as well as parental distress, depression, and anxiety. Stability was compared with the separation rate in the general population, and quality was compared using norm data from the German version of the Quality of Marriage Index (QMI-D; Zimmermann et al., 2019). A regression model was developed to predict mothers' current partnership quality.

Results: The proportion of separated and divorced people was 12.2 % compared to 14. % in the general population. Retrospectively assessed partnership quality at time of diagnosis was significantly lower than in the German general population (p < .05). Higher anxiety proved to be the most significant predictor of maternal lower partnership satisfaction assessed at the time of the survey.

Discussion: Parents of children with cancer did not show an increased separation rate. The partnership quality at the time of diagnosis was significantly lower, but was still above the cut-off of 34, suggesting predominant resilience of parental partnerships. However, some of parents showed significantly lower satisfaction. Future studies should identify parents who are more likely to experience a deterioration in partnership satisfaction or separation so that partnership interventions can be offered where appropriate.
