- Rate of exercise completion [ Time Frame: 8 weeks ]Rate of exercise completion will be measured by the number of exercises completed per subject. There are 8 exercises in total. A good rate of completion will be defined as an average of 5 or more exercises completed per subject.
- Ease of exercises [ Time Frame: 8 weeks ]Ease of exercises will be measured by a self-report 10-point Likert scale (0=not easy to complete, 10=very easy to complete). Ease will be defined as an average score of 6 or more on this scale.
- Self-reported psychological impact of exercises [ Time Frame: 8 weeks ]Psychological impact of exercises will be measured by two self-reported 10-point Likert scales. One scale measures optimism after completing the exercise (0=not optimistic, 10=very optimistic), and the other scale measures helpfulness of the exercises (0=not helpful, 10=very helpful). Psychological impact will be defined as an average score of 6 or more on both of these scales.
- Objective psychological impact of exercises [ Time Frame: 8 weeks ]
Object psychological impact of exercises will be measured by clinician-administered questionnaires given at baseline and again at 8 weeks. These questionnaires include:
- Life Orientation Test-Revised (scores range from 6-30; a high score means higher optimism)
- Gratitude Questionnaires-6 (scores range from 6-42; a high score means higher gratitude)
- Hospital Anxiety and Depression Scale (scores range from 0-42; a high score means higher depression and anxiety).
Objective psychological impact will be defined as having significantly improved scores at 8 weeks as compared to scores at baseline.
- Feasibility of step counter & pill counter devices [ Time Frame: 8 weeks ]Feasibility of these devices is measured by the amount of data we collect from 1) a step counter used for 2 weeks and 2) a pill counter used for 8 weeks. Feasibility will be defined as receiving data from both devices from more than 80% of subjects.
