Problem-Solving Therapy for Patients With Chronic Disease and Poor Mental Well-being in General Practice
Study Details
Study Description
Brief Summary
In Denmark the vast majority of patients with chronic ischemic heart disease and/or type 2 diabetes are managed in general practice. 20% of the patients suffer from poor mental health.
Problem-solving therapy (PST) is a psychotherapeutic method that is proven effective in adults with poor mental health. PST can be provided in general practice.
The main objective of this study is to test effectiveness of providing PST to this group patients.

Detailed Description
20% of patients with type 2 diabetes and/or chronic ischemic heart disease have poor mental health. Since these patients are managed in general practice interventions targeting poor mental health in these patients should be delivered in here.
Problem-solving therapy (PST) is a well-established psychotherapeutic method that can be delivered by health care providers in general practice.
The main objective of this study is to test the effectiveness of delivering PST for patients with T2D and/or IHS who suffer from poor mental health. We hypothesize that the patients' mental health will be improved after treatment with PST.
Health care providers from 12 general practices are trained in PST and subsequently provide PST for patients with T2D and/or IHS and poor mental health.
Patients are recruited at the annual control visit for the chronic disease. All patients are screened for impaired mental health with the WHO-5 questionnaire. Patients with a score below 50 are offered PST.
The study is conducted as a stepped wedge cluster-randomised controlled trial with a one-year follow-up. In this design clusters are stepped wise exposed to the intervention. Initially all general practices are in the control group. After four months half of the recruited GPs attend the PST training programme and switch to performing the intervention. After an additional four months the remaining GPs are educated in PST and all GPs now perform the intervention. Both general practitioners and practise nurses will perform PST consultations.
The power calculation is based on:
-
The primary outcome (PHQ-9 score at 6 and 12 months. The minimal clinical effect is 5 points)
-
ICC is estimated to 0,05.
Based on these assumptions we will include 194 patients with IHS and 194 patients with T2D (we expect 25% overlap) to obtain a power of 90%.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Control Patients in the control group will have unrestricted access to care as usually provided. No restrictions are imposed on the general practitioners (GPs) regarding treatment of patients with mental health problems, as we are interested in assessing the added value of PST in routine clinical practice. In both groups, GPs are recommended to follow the current guidelines. |
|
| Experimental: Intervention Patients with type 2 diabetes and/or chronic ischemic heart disease are offered up to seven problem solving therapy sessions within a three-month period from inclusion. In both groups, GPs are recommended to follow the current guidelines. |
Behavioral: Problem Solving Therapy
Problem Solving Therapy is a well-established evidence-based therapy form that is highly effective in patients with mental health issues. Initially, the patient makes a problem list and for each problem, possible solutions will be outlined. Considering pros and cons for each solution, the patient is asked to choose the one considered most appropriate. The patient is encouraged to put this solution into action and a follow-up consultation is planned.

- Mental health - Anxiety [6 months]
General Anxiety Disorder-7 (GAD-7) 6 months of follow-up
- Diabetes related stress [12 months]
Problem Areas in Diabetes-5 (PAID-5) at 12 months of follow-up
- Mental health - Depression [6 months]
Patient Health Questionnaire-9 (PHQ-9) at 6 months of follow-up
- Prescriptions of psychopharmacological medications [12 months]
Prescriptions of psychopharmacological medications during one year after start of patient-inclusion. Register-based.
- Medication adherence [Baseline and 12 months]
Changes in medication adherence to antidiabetic drugs and statins
- Lipid profile [Baseline and 12 months]
Changes in lipid profile (from blod samples)
- Blood pressure [Baseline and 12 months]
Changes in blod pressure
- Smoking status [Baseline and 12 months]
Changes in smoking status
- Use of health care services [Baseline and 12 months]
Changes in use of health care services including any contacts to general practice, out-of-hours medical service, cardiovascular readmissions and all cause hospitalizations
- Health literacy [Baseline]
Data on health literacy will be collected at baseline using the HLSAC instrument (Health Literacy for School-Aged Children), which allows the calculation of a health literacy summary score used to examine health literacy levels. HLSAC is currently being validated among adults. The summary score is between 10-40 points: 10-25 points indicates low health literacy, 26-35 points indicates moderate health literacy, 26-40 points indicates high health literacy.
