We added attributions to our list of determinants from the needs assessment because of their demonstrated interaction with self-management for other chronic illnesses and health problems (Hospers, Kok, & Strecher, 1990; Kuttner, Delamater, & Santiago, 1990; Weiner, 1985). We wanted
the child’s attributions of success to be internal and attributable to effort: “Working with my parents, doctor, and school nurse, I can control my own asthma. I don’t need grown-ups to do it for me.”
