Trial Outcomes & Findings for Financial Incentives to Improve Asthma (NCT NCT05322044)

NCT ID: NCT05322044

Last Updated: 2025-02-05

Results Overview

Comparison of average % ICS adherence measured by EMD for intervention group participants and average % ICS adherence measured by EMD for control group participants at 12-weeks (post-intervention period). EMD will electronically record date/time of asthma inhaler actuation. Data from EMD will be downloaded at study visit/s. Possible scores: 0% (poor adherence) to 100% (good adherence).

A self-report validated questionnaire to explore the child's perceptions of their asthma will be conducted at each study visit. Within and between group comparisons between groups will be explored. The B-IPQ has 8 items which are scored on a Likert scale 0-10 scoring system and an overall score is calculated. Minimum score is 0 and maximum score is 80. Overall score indicates degree in which illness is perceived threatening - higher scorer = more threatening view.

Measured by an adaptation of the Treatment Self-Regulation Questionnaire (TSRQ) for the purpose of this study. Within and between group comparisons will be explored. There are 4 items for autonomous motivation. All items are scores on a scale of 0 (not at all true) and 7 (very true). A total score is calculated from all 4 questions, minimum score 4 and maximum score 28. A higher score = higher motivation in either domain. Addition of 2 questions for intervention group only on a similar scoring scale (0 = not at all true - 7 = very true) about the influence of incentives over motivation which will be reported descriptively.

A self-report validated questionnaire to explore the child's belief in their asthma medicines will be conducted at each study visit. Within and between group comparisons between groups will be explored. The questionnaire is split into 1) BMQ specific (medicines prescribed to child) that has 10 items and 2) BMQ - general (medicines in general) that has 8 items - all with a likert scale response of strongly agree - strongly disagree. Questions can be grouped into: necessity, concern, harm and over-use. Total scores for Necessity: 5 = low belief in need for medicine; 25 = high belief in need for medicine

Timeframe: study visit 1 (0 weeks), study visit 2 (12-weeks) and study visit 3 (24-weeks)

Population: Participant numbers decrease between baseline, 12-weeks and 24-weeks due to participant withdrawal

A self-report validated questionnaire to explore the child's belief in their asthma medicines will be conducted at each study visit. Within and between group comparisons between groups will be explored. The questionnaire is split into 1) BMQ specific (medicines prescribed to child) that has 10 items and 2) BMQ - general (medicines in general) that has 8 items - all with a likert scale response of strongly agree - strongly disagree. Questions can be grouped into: necessity, concern, harm and over-use. Total score for concern: 5 = low belief in concern of medicine; 25 = high belief in concern of medicine
