Now that you know about a gratitude journal, are you likely to use a gratitude journal in the future?
Questions for parents:
Do you have any general comments about your child’s experience writing in the gratitude journal?
What was it about this experience that you think your child liked or disliked?
Now that you and your child know about a gratitude journal, do you think your child is likely to continue using one in the future?

Statistical methods / analysis
Pearsons correlations will be used to explore the relationship between the different outcome measures, demographic characteristics, disease characteristics, and current insulin regimen. Independent samples t-tests will be employed to assess group differences at follow-up on all the measures. A mixed design analysis of variance (ANOVA) will be used to assess group differences as well as within-group differences in the outcome measures. Multiple linear regression will be used to examine which measures are associated with adolescent and parental stress levels as well as adolescent glycaemic control.
