Here is the design of a clinical trial:

Official Title: Evaluation of the Occupational Therapy Intervention Program "A Better Everyday Life 1.0" - a Protocol for a Feasibility Study

Included conditions:
- Activities of Daily Living

Study Armgroups:
- {'label': 'ADL intervention', 'type': 'EXPERIMENTAL', 'description': 'The participants are assigned to an eight-week intervention program aiming at enhancing ADL ability. The program consists of a minimum of five and a maximum of eight sessions; Session one - First meeting and occupational therapy evaluation (mandatory), Session two - Goal setting and clarifying reasons for problems related to ADL (mandatory), Session three- seven - Interventions aiming at enhancing ADL ability (Number of sessions can vary. However, a minimum of two sessions are mandatory), Session eight - Re-evaluation (Mandatory)', 'interventionNames': ['Behavioral: ADL intervention']}

Interventions:
- {'type': 'BEHAVIORAL', 'name': 'ADL intervention', 'description': 'Overall, an adaptational approach is being applied. The intervention sessions include changes related to the person, the environment and/or the occupation.', 'armGroupLabels': ['ADL intervention']}

Primary Outcomes:
- {'measure': 'Assessment of Motor and Process Skills (AMPS)', 'description': "The Assessment of Motor and Process Skills (AMPS) is a standardized observation-based evaluation tool used by occupational therapists to measure a person's observed quality of ADL task performance in terms of physical effort and/or fatigue, efficiency, safety and independence. After the observation the quality of each skill is evaluated on a four point ordinal scale according to the scoring criteria in the AMPS manual.\n\nThe available AMPS software, based on Many-Faceted Rasch statistics, makes it possible to convert ordinal raw scores into overall linear ADL motor and ADL process ability measures adjusted for task challenge, skill item difficulty and rater severity. The measures are expressed in logits (log-odds probability units).", 'timeFrame': 'Change from baseline at eight weeks.'}
- {'measure': 'ADL-Interview (ADL-I)', 'description': "The ADL-Interview (ADL-I) is developed to describe and measure the ADL ability based on self-report. Using the ADL-I, the participant is asked to report their perceived ADL ability (i.e. quality of ADL task performance) for each of the 47 ADL items using seven response categories.\n\nData will be used to (a) describe the self-reported quality of ADL task performance on each task for a single person or a group of people and (b) measure a single person's overall self-reported quality of ADL task performance. To create an overall measure of self-reported quality of ADL task performance Rasch measurement methods are applied in order to transform the ratings into an overall linear (interval scale) measure of self-reported quality of ADL task performance, adjusted for the difficulty of the ADL task.", 'timeFrame': 'Change from baseline at eight weeks.'}

Please estimate the sample size based on the assumption: 
Not explicitly stated as this is a feasibility study.
Sample size
        As this study is a feasibility study, a sample size calculation is not required.44 45 However, the sample needs to be representative of the target population and to be large enough to provide information related to the feasibility and the potential outcome of the programme.45 Results from a recent study,44 using audit of sample sizes for pilot and feasibility studies conducted in the UK revealed sample sizes for feasibility studies from 10 to 300 participants. Hence, the results provide no clear guidelines on sample size estimations for future studies. In the present study, occupational therapists apply a new occupational therapy programme. As it may take some time for the occupational therapist to get experienced in applying the programme, several participants are needed. Consequently, the sample size is estimated to a total of 30 participants.
