Exercise Self-efficacySecondary· Baseline and one month from the start of the intervention
A modified version of Bandura's Exercise Self-Efficacy scale (Bandura, 1997) was used in the current study. This 9-item scale assesses how sure one is that they would exercise under different conditions or constraints (e.g. How sure are you that you will exercise when you are feeling down or depressed?), with answer choices ranging from not sure at all (1) to very sure (4). The 9 items are averaged to create a composite score, where a higher score indicates greater exercise self-efficacy (Neupert et al., 2009).

Exercise Control BeliefsSecondary· Baseline and one month from the start of the intervention
Control over exercise was measured using the 6-item Exercise Control Beliefs Scale (Neupert, Lachman, \& Whitbourne, 2009). Items assess the beliefs about one's control over exercise (e.g., I am confident in my ability to do an exercise routine), with answer choices ranging from strongly disagree (1) to strongly agree (5). The 6 items are averaged to create a mean exercise control score, with a higher score indicating greater control over exercise.

Daily Mood and Energy LevelsSecondary· Daily
Twice at random times, each day, mood and energy levels were assessed. A popup notification asked participants to rate their current mood (unhappy, neutral, happy) and energy (low, neutral, high) on a slider scale. Scores were converted by the StepMATE app to a 0-10 scale, with 0 indicating low mood/energy, and 10 indicating high mood/energy. If both mood and energy assessments were completed in one day, they were averaged to create daily average scores, one for mood and one for energy. Data presented below are the average of all daily scores across the month, while daily averages were used in

Self-Reported Vigorous Physical ActivitySecondary· Baseline and one month from the start of the intervention
Vigorous PA was measured using the question 'How often do you engage in vigorous physical activity that causes your heart to beat so rapidly that you can feel it in your chest and you perform the activity long enough to work up a good sweat and are breathing heavily?', with answer choices ranging from never (0) to several times a week (5).

Sponsor's own description
The goal of this study is to develop a smart phone app to administer a behavior change program that helps adults to increase daily steps by planning where, when, and with whom to walk. The investigators tested the effectiveness of the walking program app for increasing the number of daily steps among sedentary older adults. The investigators examined the effects on self-efficacy and social integration/support.
