Available measures of diabetes treatment adherence (1–5) are typically based on measuring deviation from a prescribed regimen and cannot readily capture problem solving and self-regulation that typify modern regimens. Measurement of diabetes self-management must accommodate these advances in therapy.
The Diabetes Self-Management Profile (DSMP), a previously validated, structured interview assessment of adherence in type 1 diabetes (6–8) was modified by the Diabetes Research in Children Network (DirecNet) research group and the authors of the DSMP to construct the DSMP for Flexible regimens (DSMP-F). This study evaluates the psychometric properties of the DSMP-F both cross-sectionally and longitudinally. Data were obtained from youths with type 1 diabetes and their parents during a DirecNet Study Group trial of the GlucoWatch G2 Biographer (GW2B; Cygnus, Redwood City, CA) (9).
RESEARCH DESIGN AND METHODS
The randomized trial included 200 youths with type 1 diabetes who were enrolled at five centers; the methodological details have been published previously (9). Each child was randomized to GW2B use or usual care. Diabetes management in both groups was similar, except for use of the GW2B. Within the sample, 161 youths were treated using flexible insulin regimens (93 on insulin pumps and 68 on “basal-bolus” regimens). HbA1c (A1C) was …
