Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a Conjoint Behavioural Consultation Model design, to target diabetes self-management knowledge and behaviours, with input from a consultant (clinical psychologist with extensive experience working with people with diabetes), consultee (experienced diabetes nurse educator) and the individual participant with type 1 diabetes. The intervention requires 6 individual (up to 1 hour) sessions over approximately 8 weeks, via a combination of face to face and remote/ virtual visits. After the intervention phase, there is one follow up visit at 3 months and again at 6 months.
Data collection includes self-reported diabetes self-management actions, surveys and clinical measures such as glycated hemoglobin.
Principles of diabetes self-management education and behavioural psychology will guide the intervention, that will target active coping and positive diabetes self-management behaviours with the aim of improving diabetes related health outcomes.
Intervention code [1] 315134 0
Behaviour
Comparator / control treatment
Participants will act as their own control, as per a 'single case research methods' design (baseline / intervention phase / return to baseline phase).
Standard care (i.e. outpatient diabetes clinic appointments) will continue while participants are enrolled in this pilot study.
Various process and glycaemic measures will be assessed at baseline, then re-assessed at 3 months and 6 months post the intervention phase to measure any lasting effects from the intervention.
Control group
Active

Outcomes
Primary outcome [1] 320877 0
Individual diabetes self-management will be assessed with a self-reported questionnaire and participant log book. Historical data from glucometer or insulin pump will also be uploaded to obtain further glucose and insulin data.
Timepoint [1] 320877 0
Measured at baseline, end of intervention, 3 months and 6 months post intervention
Primary outcome [2] 320887 0
Time in target glucose range will be measured, where possible, with participants own glucose sensor data.
Timepoint [2] 320887 0
Data from participants own continuous glucose sensor will be requested, where possible, at baseline, end of intervention and 6 months.
Secondary outcome [1] 373210 0
Diabetes distress will be measured using a validated diabetes distress scale (T1-DDS)
Timepoint [1] 373210 0
Measured at baseline, end of intervention, 3 months and 6 months post intervention
Secondary outcome [2] 373212 0
Glycated haemoglobin will be assessed via laboratory (serum assay) or point of care test.
Timepoint [2] 373212 0
Baseline, end of intervention and end of study (6 months)

Eligibility
Key inclusion criteria
1. Diagnosis of type 1 diabetes for at least 12 months
2. Aged 18 to 50 years.
3. Glycated haemoglobin within the previous 6 months > 8% And/ OR clinically significant diabetes distress score
Minimum age
18 Years
Maximum age
50 Years

Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Pregnancy or breastfeeding
2. Non-English speaking
3. A level of disability that prevents independence in diabetes self-management.
4. A psychiatric disorder which in the opinion of the researchers would preclude participation in the intervention.
5. Inability to adhere to the protocol and study visits.
6. Use of Psychotropic medication will not automatically be an exclusion criteria, if the dosage has been stable for the past 3 months and will continue to be stable during the intervention period. Any changes in medication during the study period will be noted along with the other measurements at all stages.

Other design features
Single case research methods, using a reversal design (ABA pattern). This design involves a sequence of experimental conditions from non - intervention (A) to an intervention phase (B) and then back to a non-intervention phase (A).

Efficacy
Statistical methods / analysis
Single case research design allows assessment of the effects of the independent variable on the outcome measures, via intra-subject replication. The mechanism for measuring outcomes is through replications within the same participant (intra-subject), and across participants (inter-subject), with multiple data points. Individual participants are compared with themselves under the experimental conditions. Clinical significance is measured to demonstrate treatment effectiveness, determined by: effect size, visual/graphical inspection of data, process measures, measures of social validation.

Summary
Brief summary
This study will test a (one to one) diabetes self-management intervention that targets active coping with diabetes related goals, that are identified as most important to the individual throughout the intervention. We will test if this style of intervention is acceptable and effective and results in positive changes in diabetes self-management, glucose levels and well-being measures including diabetes distress. There will be the opportunity for some or all of the study visits to be completed remotely (e.g., via phone, or online platform). To be eligible for this study you will be aged from 18 to 50 years, diagnosed with type 1 diabetes for at least one year, your HbA1c within the preceding 6 months was at or above 8% OR based on your score on a diabetes distress survey. Information will be collected via surveys, medical records where possible, and some self-reported information.
