Interactive Tool to Support Self-management Through Lifestyle Feedback, Aimed at Physical Activity of COPD/DM Patients

Physical activity will be measured with the Personal Activity Monitor (PAM). The PAM is a small (58 x 42 x 13 mm, weight 28 gram) tri-axial accelerometer that can be easily attached to a belt and is worn on the hip. The PAM registers all movements that are made on a day and measures the intensity of hip movements. Via a docking station, which must be connected to the internet, the PAM scores can be uploaded and converted into minutes a day in a sedentary category (< 1.8 METS) a living category (1.8-3 METS) a moderate category (3-7 METS) and a vigorous category (>7 METS). The number of minutes of physical activity in the moderate and vigorous category is used as an outcome measurement. The possibility of noticing (e.g. providing feedback) users about their activity scores and their calories used will be deactivated; the displays will be turned off. The level of physical activity in minutes a day at t0 will be compared to the minutes of activity at t1 and t2.

To measure the quality of life of participants the Dutch version of the SF-36 will be used (see appendix F1.3). The SF-36 is a generic health status instrument designed for the use across a wide range of chronic disease populations. "The SF-36 has shown an excellent reliability and validity in diverse patient populations in the US and the Netherlands. The SF-36 is composed of 36 items, organized into 8 multi-item scales covering a similar number of dimensions, including physical functioning, physical role functioning, bodily pain, general health, vitality, social functioning, emotional role functioning, and mental health.". A higher score on the SF-36 indicates a better quality of life.

Self-efficacy is described as people's belief in their capability to organize and execute the course of action required to deal with prospective situations. Self-efficacy is an important construct since it influences the processes of planning, taking initiative, maintaining behaviour change, and managing relapses.

To measure self-efficacy of participants two questionnaires will be used: the Dutch adaptation of the General Self-Efficacy Scale (GSE) from Jerusalem and Schwarzer (1995) and the Dutch adaptation of the Exercise Self-efficacy Scale (ESS) developed by Bandura (1997). The GSE contains 10 questions in a 4 points response format and the ESS contains 18 questions regarding different situations related to exercise with a scale response format from 0-100.

Personal reported health status will be measured by a disease specific questionnaire.

For diabetes the Diabetes Symptom Checklist-revised (DSC-R) will be used. On the 34 items of the DSC-R, participants first indicate whether they have experienced each symptom in the past 4 weeks. If "yes" is selected, the participant continues to rate how troublesome that symptom is on a 5-point scale ranging from 1 (not at all) to 5 (extremely). The instrument yields a total score and the following subscales: Fatigue, Cognitive, Pain, Sensory, Cardiology, Ophthalmology, Hypoglycemia, and Hyperglycemia. The total score and all dimension scores range from 0 to 5. Higher scores indicate greater symptom burden.

For COPD the Chronic Respiratory Questionnaire (CRQ) will be used. The CRQ consists of four domains: fatigue, dyspnoea, mastery (the patient's feeling of control over their disease), and emotional function.

The PAM scores and the number of minutes of PA in the living, moderate and vigorous category >1.8 METS. These measures indicate all types of activity during the day.

If available in the medical record of the general practitioner, disease specific health outcomes will be extracted, such as CCQ, MRC values for COPD patients and Hba1C blood values for diabetes patients, blood pressure and BMI.
