ABSTRACT
OBJECTIVE:
To develop and validate new measures of diabetes-specific health-related quality of life (HRQOL) for people with type 1 diabetes (T1D) that are brief, developmentally appropriate, and usable in clinical research and care. Here we report on the phases of developing and validating the self-report Type 1 Diabetes and Life (T1DAL) measures for children (age 8-11) and adolescents (age 12-17).METHODS:
Measure development included qualitative interviews with youth and parents (n = 16 dyads) followed by piloting draft measures and conducting cognitive debriefing with youth (n = 9) to refine the measures. To evaluate the psychometric properties, children (n = 194) and adolescents (n = 257) at three T1D Exchange Clinic Network sites completed the age-appropriate T1DAL measure and previously validated questionnaires measuring related constructs. Using psychometric data, the investigators reduced the length of each T1DAL measure to 21 and 23 items, respectively, and conducted a final round of cognitive debriefing with six children and adolescents.RESULTS:
The T1DAL measures for children and adolescents demonstrated good internal consistency (α = 0.84 and 0.89, respectively) and test-retest reliability (r = 0.78 and 0.80, respectively). Significant correlations between the T1DAL scores and measures of general quality of life, generic and diabetes-specific HRQOL, diabetes burden, and diabetes strengths demonstrated construct validity. Correlations with measures of self-management (child and adolescent) and glycemic control (adolescent only) demonstrated criterion validity. Factor analyses indicated four developmentally specific subscales per measure. Participants reported satisfaction with the measures.CONCLUSIONS:
The new T1DAL measures for children and adolescents with T1D are reliable, valid, and suitable for use in care settings and clinical research.Key words
