This instrument measures quality of life for parents who have children with a chronic disorder. It includes 36 items concerning physical, emotional, social and cognitive functions as well as daily activities, family relations, communication and family worry. Items are answered on a five-grade scale from 0 = never a problem, to 4 = almost always a problem. These result for each item is transformed so that 0 = 100, 1 = 75, 2 = 50, 3 = 25, 4 = 0, and the sum score is divided by the number of items, so that higher score indicates higher quality of life.

This is a 16-item measure that aim to measure aspects of parenting self-regulation, representing the degree to which participants perceive themselves as efficacious and competent in their role as parents. The scale includes 16 items covering the four subdomains of self-efficacy, personal agency, self-sufficiency and self-management. Items are rated on a scale from 1 = strongly disagree, to 5 = strongly agree.

This 2-item questionnaire is developed by the research group and aims to serve as a parent-reported proxy for the two key self-management behaviors: taking insulin and handling high and low blood glucose values. In percentages from 0-100%, parents are asked to estimate to what extent their child 1) takes insulin and 2) handles high and low blood glucose values, in relation to all the times these behaviors are required.

This questionnaire is developed by this research group and based on common diabetes-specific themes of parental, behavioral challenges reported by parents in an interview study conducted by the group. In 12 items, parents are asked to rate how often they experience a set of challenges on a Likert scale from 0 = never, to 4 = always. These items cover four domains 1) parent worry and frustration, 2) talking, asking and reminding 3) child resistance to self-management routines, 4) child resistance to communication about self-management. This is a pilot use of the questionnaire, testing the items before deciding on future validation and psychometric evaluation. We will also use it to look at participants responses over time at a qualitative, clinical and explorative level and to investigate how the domains relate to eachother, to glycemic control and how/if responses change over time.

This 7-item version of the GAD questionnaire is a short measure of symptoms of anxiety. Participants are asked how often they have been bothered by a set of anxiety symptoms the last 2 weeks ranging from 0=not at all, to 7=daily. The measure will serve as a control variable in mediation analyses.

This is a 37 item questionnaire that aims to measure health related quality of life in children living with chronic conditions. Added to this questionnaire is the diabetes module with 10 diabetes-specific items. Questions concern aspects of how often the condition affects different aspects of every-day-life, such as whether the child feels lonely due to his/her condition, or if he/she is bothered by the medical treatment. It is scored using five ordinal response categories ranging from "never" to "always." The negative oriented items are coded 4 ("never") to 0 ("always") whereas the positive oriented questions are inverted, so that higher score indicates higher health related quality of life.

This questionnaire is newly developed by the research group and is to be piloted in the current study. The length of questionnaire is adapted to individual CBT treatments depending on the number of treatment components that are presented. One week after a new behavioral strategy and an associated assignment have been presented to the participants, they are asked to rate their engagement according to the following three domains:

1. Frequency: how many days they have used the strategy (1 - 7),
2. Intensity: how much effort they have put down in using it (0 = none, to 5 = a lot).
3. Usability: how helpful they perceive the strategy to be for them (0 = not at all, to 5 = very).

The total score for each of the 3 domains are divided by the number of strategies, to reach a mean score for each of the three domains. Results will be examined at a qualitative level to guide further refinement of the intervention.
