Title: Patient Perception of Symptom Variability. A Cross-sectional Study of Patients With Severe COPD.
Brief Summary: This study is investigating how patients with severe stable state COPD perceive the variability of their symptoms throughout the day, the week and the year; the impact of these variations on their daily activities or sleep quality and how they deal with their treatments. For this purpose patients will be asked to answer a questionnaire over the phone


Options:
A: Inclusion Criteria:

* participants must have a diagnosed COPD, be over 40 years and have no other medical barriers to participate in training at home with the e-health program.

Exclusion Criteria:

* medical barriers to participate in training at home with the e-health program.
B: Inclusion Criteria:

To be eligible for inclusion in this study Patients fulfil all of the following criteria:

1. Written informed consent obtained before any assessment is performed.
2. Male and female patients ≥ 40 years of age
3. Diagnosis of COPD \[post-bronchodilator forced expiratory volume at one second (FEV1) \<80% predicted and FEV1/ forced vital capacity (FVC) \<75% without significant post-bronchodilator reversibility (\<10% FEV1 % predicted normal)\]
4. Optimal medical treatment according to GOLD without regular use of systemic corticosteroids
5. Current or ex-smokers with a smoking history equivalent to at least 10 pack years (1 pack year = 20 cigarettes smoked per day for 1 year)
6. Absence of other significant diseases that could contribute to exercise limitation
7. At least 2 COPD exacerbations the year before the time entry

Exclusion Criteria:

Patients fulfilling any of the following criteria are not eligible for inclusion in this study. No additional exclusions are applied by the investigator, in order to ensure that the study population will be representative of all eligible patients.

1. Orthopedic, neurological or other complaints that significantly impair normal biomechanical movement patterns, as judged by the investigator. Specifically if the patients' condition/ co-morbidities are such that physical activity cannot be increased.
2. Respiratory diseases other than COPD (e.g. asthma)
3. Cognitive reading impairment and/or difficulties to manage electronic devices precluding interaction with the tablet, as judged by the investigator
4. Patients not on optimal pharmacotherapy
5. No COPD exacerbations the year before the time entry
C: Inclusion Criteria:

* Outpatients with a diagnosis of COPD
* FEV1\<50% and FEV1/FVC\<0.7 according to lung function data in medical records.
* Smoker or ex-smoker \> 10 pack-years
* Informed consent obtained

Exclusion Criteria:

* Ongoing exacerbation of COPD or within the previous 3 months
* Any other significant respiratory disease (including asthma and allergic rhinitis)
D: Inclusion Criteria:

* People diagnosed with COPD or diabetes type 2 who are predominantly treated in primary care and who benefit from more physical activity, will be included. -This means patients who do not comply with the Dutch Norm for Healthy Exercise (30 minutes activity per day of a moderate intensity during five days a week)
* Their age should be between 40-70 years to ensure homogeneity in the groups
* Additional inclusion criteria for the diabetes group are a recent (no longer than a year ago) HbA1c concentration of more than 7% / more than 53 mmol/mol and a body mass index of more than 25kg/m2

For the COPD group the following additional inclusion criteria apply:

-A clinical diagnosis of COPD according to the GOLD-criteria stage 1, 2 and 3 (post bronchodilator FEV1/IVC \<= 70% and FEV1 between 30 and 80% of the predicted value); at least six weeks respiratory stable and on a stable drug regimen

Exclusion Criteria:

-Patients older than 70 years are not included because of a bigger risk for co-morbidity and a higher chance of mobility problems (balance)
