The goal of this study is to explore a new intervention that supports physical activity within the first 6 weeks after stroke. All participants will complete assessments at weeks 0 and 7. During weeks 1 through 6, participants will use a Fitbit Inspire to track their step counts and meet with an occupational therapist one time per week. They will also complete weekly surveys. Physical activity levels will be measured using surveys and a wearable activPAL monitor 6 times during the study: Weeks 1, 3, 5, 7, 12, and 24.

PA-ChatS consists of (1) self-monitoring step count using a Fitbit Inspire, and (2) behavioral activation for stepping activity delivered via the telephone and guided by the PA-ChatS workbook. Participants will receive education regarding the physical activity after stroke, American Heart/Stroke Association guidelines for post-stroke physical activity levels, and an overview of the intervention activities. They will then use the Fitbit data to monitor average daily step counts, set a new step count goals (increasing by 5 to 10% of the daily average step count from the prior week), and create a specific plan for achieving the new step count goal. The interventionist will collaboratively problem solve with the participant to identify strategies to overcome barriers to stepping activity and maintain safety.

Adherence to PA-ChatS sessions
Percentage of participants who complete 6 out of 6 (100%) of PA-ChatS sessions. Session completion will be documented by the study intervention therapist and total count of sessions completed will be computed after the last intervention session is delivered.
Time frame: 6-weeks
Adherence to wearable activity tracker
Percentage of participants who use the wearable activity tracker (Fitbit Inspire 3) an average of 5 of 7 days/week during the 6-week intervention period. Data will be exported from Fitbit to compute average number of days per week the Fitbit was used.
Time frame: 6-weeks
Acceptability of PA-ChatS Intervention
The Client Satisfaction Questionnaire-8 will be used to measure acceptability of the intervention. This is an 8-item measure with each item rated on a 1 to 4-point Likert-type scale, and then averaged across all 8 items. A mean score of 3 or more indicates that the intervention is generally acceptable.
Time frame: Week 7
Safety of the PA-ChatS intervention
All participants will be queried regarding possible adverse events during the study at one time-point using an adverse events questionnaire previously administered in physical activity studies after stroke.
Time frame: Week 7
Change in step count
The activPAL micro4 will be used to measure step count, following a 24-hour, 7-day wear protocol.
Time frame: Weeks 1 to 12
Change in sedentary time
The activPAL micro4 will be used to measure sedentary time, following a 24-hour, 7-day wear protocol. Participants will complete a daily diary indicating the sleep time. Sleep will be removed following a diary-informed method.
Time frame: Weeks 1 to 12
Adherence to step count
The activPAL micro4 (24/7 wear protocol) will used to measure step count. The proportion of participants achieving 7500 or more steps per day will be reported.
Time frame: Week 24
Adherence to sedentary time
The activPAL micro4 (24/7 wear protocol) will used to measure sedentary time. Participants will complete a diary to indicate sleep time, and sleep will be removed following a diary-informed method. The proportion of participants achieving 7 hours or less of sedentary time per day will be reported.
Time frame: Week 24
Adherence to moderate-to-vigorous physical activity
The International Physical Activity Questionnaire will used to measure minutes per week of moderate-to vigorous-physical activity (MVPA). The proportion of participants achieving 90 minutes or more/week of MVPA will be reported.
Time frame: Week 24
Adherence to strength training
The Muscle-Strengthening Exercise Questionnaire Short Form will used to measure days per week of strength training. The proportion of participants achieving 2 or more days per week of strength training will be reported.
Time frame: Week 24
