Brief summary
This study is a randomized prospective trial with 6-month follow up. A non-inferiority hypothesis is tested. A new developed treatment and education programme for type 1 diabetic patients (PRIMAS) will be tested compared to an established treatment and education programme (German DTTP). Primary outcome variable is glycemic control at 6-month follow up. Secondary outcome variables are: diabetes knowledge, diabetes related distress, depressive symptoms, diabetes self-efficacy, self-care behavior, attitudes towards diabetes and insulin treatment, hypoglycemia awareness.
Detailed description
Both programmes consists of 12 lessons with a length of 90 minutes. Eligible type 1 diabetic patients in a diabetologist practice are pooled and randomised either to the new developed PRIMAS programme or to an established education programme for type 1 diabetic patients (DTTP - Treatment and education programme for intensified insulin treatment) as an active comparator.
Interventions
PRIMAS is a newly developed treatment and education programme for type 1 diabetic patients. It consists of 12 lessons (duration 90 minutes each), slides for diabetes educators and patient material

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in Glycemic Control Measured by A1c | Baseline and 6 months | Difference between baseline A1c and A1c at 6 month follow up. Equivalent effect on glycemic control measured by A1c (non-inferiority). In case of-non-inferiority test of superiority. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hypoglycaemia Awareness Score | 6 month | The hypoglycemia awareness questionnaire provides a score indicating the severity of hypoglycaemia unawareness. This scale ranges from 0 (maximum hypoglycaemia awareness) to 7 (minimum hypoglycaemia awareness), where a score of 4 suggests reduced hypoglycaemia awareness. |
| Diabetes Empowerment Score (DES) | 6 month follow up | Empowerment was measured by a German version of the Diabetes Empowerment Scale, a measure of diabetes-related psychosocial self-efficacy. |
| Summary of Diabetes Self-Care Activities (SDSCA) | 6 month | The Summary of Diabetes Self-Care Activities (SDSCA) measure is a self-report measure of diabetes self-management assessing several aspects of the diabetes regimen. |
| Diabetes Distress Scale (DDS) | 6 month follow up | Diabetes related distress was assessed by a German version of the Diabetes Distress Scale (DDS). The DDS is a 17-item self-report scale for the assessment of emotional burdens in diabetes treatment in both type 1 and type 2 diabetes. |
| Diabetes Knowledge | 6 month | To assess knowledge among insulin-treated diabetes patients, participants completed a new developed 11-item diabetes knowledge score. Each item had to be answered by selecting the correct answer from multiple choices. The numbers of correct answers are summed up; thus, the range of the diabetes knowledge score is between 0 and 11. |
| Diabetes Self-Efficacy Scale | 6 Month Follow up | A German version of the Diabetes Self-efficacy Scale was used to assess diabetes specific self-efficacy. |
| Treatment Satisfaction / Problem Areas in Dealing With Diabetes | 6 Month Follow up | Satisfaction with current diabetes treatment was assessed by a diabetes satisfaction questionnaire developed by Kulzer et al. This questionnaire uncovers problems in dealing with diabetes, also. A high score indicates dissatisfaction with insulin therapy. |
| Evaluation of the Diabetes Education Course | 6 month Follow up | Patients satisfaction with the diabetes education programs was assessed using a self-constructed 12-item scale on specific questions regarding contents and performance of the training. Response mode was a scale ranging from 4 (apply very strong) to 0 (apply not at all). Additionally, patients were asked to give an overall grade for their course ranging from 1 (very good) to 6 (unsatisfactory). |
| CES-D Score | 6 month follow up | Depressive symptoms were assessed using the German version of the Centre for Epidemiologic Studies Depression Scale (CES-D), an instrument for measuring number and severity of depressive symptoms. |
Participant flow
Recruitment details
The participants were recruited in 23 outpatient study centres, which were located all over Germany. A study centre was defined as a medical practice run by a diabetologist and a diabetes educator or diabetes nurse.
