Experimentell: Control group
Participants will wear a Fitbit Zip to record their daily activity data, which will be deidentified and aggregated with an online platform called Fitabase.
Participants in the control group will be matched with the intervention group for how much contact they have with the researcher.
|
Participants will wear a Fitbit Zip for 5 weeks to record their daily activity data.
The first week of the study will provide a baseline measurement of activity.
After this week, participants in this condition will begin receiving daily emails asking them to report their step count in a questionnaire.
Participants in the control group will be matched with the intervention group for how much contact they have with the researcher.

Experimentell: Implementation Intention Condition
Participants will wear a Fitbit Zip to record their daily activity data, which will be deidentified and aggregated with an online platform called Fitabase.
Participants in this arm will receive all components of the intervention: scheduling, maps, and activity goals.
|
Participants will wear a Fitbit Zip for 5 weeks to record their daily activity data.
The first week of the study will provide a baseline measurement of activity.
After this week, participants will be asked to increase their steps incrementally by 2,000 steps each week for the subsequent four weeks.
To help achieve their step goals, they will receive maps of different routes near their home and/or work of varying distances and step counts.
They will be asked to review their schedule for the next day and identify times when they could add steps into their schedules, and to record their daily step data in the daily questionnaire.

Cognitive Composite Score
Tidsram: Baseline (Pre-Test) and Week 5 (Post-Test )
|
Z-score composite on the Brief Test of Adult Cognition by Telephone (BTACT).
Individual tests scores were first standardized to z-scores.
The z-score composite was calculated by averaging the z-scores of the 5 tests: word list immediate, word list delayed, backwards counting, digits backwards, and category fluency.
Post-test z-scores were standardized based on the mean and s.d. of the pretest scores.
A higher z-score is indicative of better cognitive functioning.

Baseline (Pre-Test) and Week 5 (Post-Test )

|
Exercise Control Beliefs
Tidsram: Baseline (Pre-Test) and Week 5 (Post-Test )
|
Degree of perceived control over Exercise.
Range from 1 (Strongly agree) to 5 (strongly agree).
Reverse coded so that a higher number indicates more perceived control over exercise.
|
Baseline (Pre-Test) and Week 5 (Post-Test )
|
|
Exercise Self-efficacy
Tidsram: Baseline (Pre-Test) and Week 5 (Post-Test )
|
Amount of confidence in ability to exercise.
|
Baseline (Pre-Test) and Week 5 (Post-Test )

Exercise Self-efficacy Beliefs - Time Composite
Tidsram: Baseline (Pre-Test) and Week 5 (Post-Test )
|
Amount of confidence in ability to exercise when facing time constraints.
Range from 1 (Very Sure) to 4 (Not sure at all).
Reverse coded so that a higher number indicates more self-efficacy.
3 items, summed to form time-relevant composite scale.
