Diabetes Health Profile

Diabetes Health Profile (DHP-1)

Based on a conceptual model the DHP-1 was developed for people with Type 1 diabetes to assess the impact of living with diabetes has on patients quality of life1. Developed using a multimethod methodology including, in-depth interviews with patients, clinical consensus and extensive psychometric validation, the DHP-1 comprises 32 items which are summed to provide three domain scores measuring: Psychological distress – (14-items) (dysphoric mood, feelings of hopelessness, irritability, self-harm, feeling of external hostility); Barriers to activity (13-items) (perceived limitation to activity, operant anxiety) and Disinhibited eating (5-items) (lack of eating control, response to food cues and emotional arousal). The observed Flesch Kincaid readability statistic is 5.8 for the DHP-1 and a Flesch reading ease is 74.7. Completion time is approximately 9–12 minutes. The DHP-1 has demonstrates highly satisfactory measurement properties including reliability coefficients 0.80, construct, convergent and criterion validity and ability to discriminate between patients experiencing hypoglycaemic episodes.

Diabetes Health Profile (DHP-18, DHP-3D & DHP-5D)

The DHP-18 was developed for people with Type 1 and Type 2 diabetes to measure the impact of living with diabetes on the patient's quality of life(5). It comprises 18 items which capture the three key domains based on a conceptual model and conceptual framework identified for the DHP-1. These are, Psychological distress – 6-items (dysphoric mood, feelings of hopelessness, irritability); Barriers to activity 7-items ( perceived limitation to activity, operant anxiety) and Disinhibited eating 5-items (lack of eating control, response to food cues and emotional arousal). The observed Flesch Kincaid readability statistic is 4.5 for the DHP-1 and a Flesch reading ease is 83.0. Completion time is approximately 5–6 minutes.

The DHP-18 has demonstrated very good measurement properties including reliability coefficient 0.70 and the ability to discriminate between different treatment and patient groups.

Both the DHP-3D and DHP-5D can be used to provide condition-specific utility values to complement generic utilities from more widely validated measures such as the EuroQol-5 Dimension.

Scoring the DHP

Items are scored using a 4-point Likert-type scale ranging from 0-3. Domain raw scores are transformed to a common score range of 0-100, with 0 representing no dysfunction.

Uses

• Evaluating health improvement and quality of life
• Monitoring population quality of life
• Evaluating health programmes and quality of life
• Evaluating treatment effectiveness and quality of life
• Enhancing doctor-patient communication
• Provide condition-specific utility values to complement generic utilities from more widely validated measures
