The overall aim was to describe and compare well-being, social life, and quality care among parents of children with cancer with respect to mothers versus fathers and whether the children were on versus. off treatment. The Life Situation Scale for Parents (LSS-P) was answered by 320 parents, comprising 85 mothers and 71 fathers of children on treatment, and 93 mothers and 71 fathers of children off treatment. The results show that the well-being of parents of children with cancer is affected by their child's situation, and that they experience such things as economic strain and a sense of being dependent on the care provided, especially during the child's treatment phase. Mothers whose children are receiving treatment see their life situation as less satisfying, and report being sadder and having lower self-esteem.
