Diabetes Self Management Technology Questionnaire (DSMT-Q)
The Diabetes Self-Management and Technology Questionnaire (DSMT-Q) is a patient reported measure that has been developed to assess self-management among people living with type 2 diabetes who use web-based and mHealth technologies. Available to use in two versions (web-based and mHealth technologies users and non-users).
Background
The DSMT-Q includes 13 questionnaire items over two sub-scales. Understanding individual health and making informed decisions (7 items) and Confidence to reach and sustain goals (6 items).
The DSMT-Q has been developed with both patient and expert input and can be used in a range of applied settings. Whilst the questionnaire has been designed to ensure relevance to people living with type 2 diabetes who are using web-based and mHealth technologies, items are also applicable to those who are not using technology to manage their health. As such, this instrument may be used in a variety of contexts where a comparator group receives standard care or non–technology-based resources.
This tool is fully compliant with relevant regulatory bodies, such as the FDA and EMA and has shown good psychometric properties.

Design and development
-
The content of the DSMT-Q was informed by an initial study that undertook in-depth qualitative interviews (n=15) with people living with type 2 diabetes in order to explore experiences of using web-based and mHealth technologies to manage their health. On completion of the interviews, 36 items were developed and refined following cognitive debrief interviews with people living with type 2 diabetes, expert consultation, and public patient involvement (PPI) feedback. Item reduction steps were performed on survey data (n=250), and psychometric validation of the remaining candidate items using appropriate quantitative methods were carried out. The two subscales identified via the study show high construct validity, internal consistency and test-retest reliability. The validation phase was conducted entirely via electronic COA means (eCOA).

Scoring system
-
A scoring guide is available for researchers. This includes sub scale calculations. Individual item responses are coded from 0-4 with a score ranging from 0 to 100 where a lower score indicates lower self-management.
-
Administration methods
-
Available to use in two versions (web-based and mHealth technologies users and web-based and mHealth technologies non-users), for electronic completion.
-
Complementary measures
-
Due to its focus on the use of technology to aid self-management, the DSMT-Q can be usefully integrated with other measures of self-management or quality of life for people with type 2 diabetes. In our portfolio, for instance, the HASMID, a mixed health related quality of life and self-management instrument, and the DHP, which measures the impact of diabetes 1 and 2 on the behaviour and psychology of patients.
