“…In type 1 diabetes, for example, there are at least six different components of the treatment regimen (insulin administration, exercise, types of foods consumed, amount of calories consumed, frequency of food consumption and glucose testing, and concentrated sweet consumption) that are all unrelated to each other (see Johnson, 1992, for a review). Variance in adherence across different components of a complex treatment regimen has been documented for many diseases and conditions including hypertension (Kravitz et al, 1993), cystic fibrosis (Passero, Remor, & Salomon, 1981), epilepsy (Hazsard, Hutchinson, & Krawiecki, 1990), diabetes (Orme & Binik, 1989), and orthodontics (Gross, Samson, Sanders, &. Smith, 1988), suggesting that single indicator assessments of adherence will prove inadequate in many, if not most, situations.…”
