Health State Descriptions Time Begin
Now I would like to review different functions of your body. When answering these questions, I would like you to think about the last 30 days, taking both good and bad days into account. When I ask about difficulty, I would like you to consider how much difficulty you have had, on an average, in the past 30 days, while doing the activity in the way that you usually do it. By difficulty I mean requiring increased effort, discomfort or pain, slowness or changes in the way you do the activity. Please answer this question taking into account any assistance you have available.
Sleep and Energy
In the last 30 days, how much of a problem did you have due to not feeling rested and refreshed during the day?
Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
By problem, we mean a reduced level of energy and vitality and how it affected daily life, e.g. inability to complete tasks or days missed off work for example as the person lacked the energy he/she usually has to carry on activities.
