Stepping up, stepping back, being pushed, and stepping away : the process of making treatment decisions for children with cancer by parents who no longer live together
… Using grounded theory techniques, the process of stepping up, stepping back, being pushed, and stepping away in making treatment decisions was described by parents. The process depicted differing levels of parent involvement based on the parent's position in the family, involvement with the child …
