Here is the design of a clinical trial:

Official Title: Evaluation of an Intervention Program Addressing Reablement Services in a Swedish Context (ASSIST 1.0) - A Protocol for a Feasibility Study

Included conditions:
- Older Adults
- Participation

Study Armgroups:
- {'label': 'ASSIST 1.0', 'type': 'EXPERIMENTAL', 'description': "A ten-week intervention program using a person-centred approach to support the older person to set up goals to perform daily activities that he/she wants or needs to do. The activity goals will target improvements in quality of life, physical health, mental well-being, and conditions for social community. The focus will be on supporting the older person's activities in everyday life that are considered meaningful for the individual. During the intervention, a specially designed application will send reminders and feedback related to the older adults' activity goals of doing their prioritized everyday activities both to the older adults and to the home care providers via mobile phones, tablet etc. The home care providers will participate in coaching sessions supporting the intervention held by the team of researchers.", 'interventionNames': ['Behavioral: ASSIST 1.0']}
- {'label': 'Ordinary home care services', 'type': 'NO_INTERVENTION', 'description': 'The home care providers in the control group (CG) will provide services as usual to older adults participating in the control group. They will however, identify potential older persons to participate in the control group according to the same procedure and criteria as the intervention group.'}

Interventions:
- {'type': 'BEHAVIORAL', 'name': 'ASSIST 1.0', 'description': '10 weeks intervention applying a person-centred approach by using goal setting and smart products.', 'armGroupLabels': ['ASSIST 1.0']}

Primary Outcomes:
- {'measure': 'Change in Canadian Occupational Performance Measure (COPM)', 'description': "Measuring the older adults' self-perception of activity performance and satisfaction within the areas of self care, productivity and leisure, measured on a 1-10 scale, where 10 represents most satsified and highest performance ranking.", 'timeFrame': 'Change between baseline and 8 to 10 weeks post baseline.'}

Please estimate the sample size based on the assumption: 
Statistics and tests will be reported in accordance with the CONSORT 2010 statement and its extensions for non-pharmacological treatment trials.
Sample size and power considerations
        As this study is a feasibility study, a sample size calculation is not required.51 52 However, the sample should be representative of the target population and be large enough to provide information related to the feasibility and the potential outcome of the programme.52 If the programme is feasible and reveals positive outcomes, the intention is to evaluate the outcomes of the programme in a future large-scale RCT. Initially, such a study will include a pilot period. If no adjustments of the ASSIST programme are required, the data from the pilot period might be included in the large-scale RCT (internal pilot).53 Furthermore, the results of the feasibility study and the pilot period will be the basis for a power calculation for the future large-scale study and thereafter, a sample size justification should51 be presented for phase IIIâthe RCT design in this project (figure 1).
        All statistics and tests will be reported in accordance with the Consolidated Standards of Reporting Trials (CONSORT) 2010 statement54 in conjunction with the CONSORT 2010 extensions for randomised trials of non-pharmacological treatment.55 56
