Pink Warrior 2: Teleconference-based Gaming Support

Difference in mean of daily steps taken from Actigraph accelerometer worn for 7 day period from baseline assessment to 14 week assessment

Quality of life score as measured by the Functional Assessment of Cancer Therapy-Breast measure at follow-up, scored for physical, social, emotional, functional, and breast well-being (here we report the total score of these subscales). The range for this scale is 0-123, with 0 indicating a better outcome.

Difference in physical performance as measured by Short Physical Performance Battery from baseline to 14 weeks. The numbers reported here are the sum of scores from the subscales. The range for this measure is between 0-12, with lower scores indicating better outcomes.

Walking skills as measured by the Figure-of-8 Walk test

Flexor muscle strength of hand and forearm measured by dynamometer

Physical function scores on six components: chair stands, arm curls, chair sit and reach, back scratch, 8 foot up and go, and 2 minute step in place test

Mean body weight as measured by a calibrated scale in a cancer clinic setting

Mean waist circumference as measured by Seca-203 measuring tape

Dietary pattern change measured by the National Health and Nutrition Examination Survey (2009-10) measuring fruits, vegetables, dairy/calcium, added sugar, whole grains/fiber, red meat, and processed meat consumption within the past 30 days

Minutes of physical activity as self-reported using the Community Healthy Activities Model Program for Seniors questionnaire

Physical function score as measured by the PROMIS cancer-specific instrument (PROMIS-CA Bank v1.1-Physical Function)

Fatigue score as measured by the PROMIS cancer-specific instrument (PROMIS-Ca Bank v1.1-Fatigue)

Autonomous regulation as measured by the Behavioral Regulation in Exercise Questionnaire-2

Perceptions of autonomy, competence, and relatedness as measured by the Basic Psychological Needs in Exercise scale. 11 items on a 5-point Likert scale. Range: 1 (I do not agree at all) to 5 (I completely agree) for each of the constructs-autonomy (1-20), competence (1-20), and relatedness (1-15). The higher the score means more autonomy, more competence, and relatedness.

Goal-setting and planning measures, adapted from a published, untitled series of items created by Rovniak et al for evaluation of technology-mediated health promotion content. 10 EGS and 10 EPS items on a 5-point Likert scale. Range: 1 (does not describe) to 5 (describes completely) of the goal setting and planning strategies. The higher the score means more exercise goal-setting and planning behavior. (Rovniak et al. Annals of Behavioral Medicine, 2002, 24(2): 149-156.)

Adherence as measured by number of participants who complete at least 80% of program activities

Attrition as measured by percentage of people who drop out of the program

Technological issues will be measured by counting the number of reported occurrences

Adverse events will be measured by counting the number of occurrences

Acceptability and satisfaction will be assessed via Vandelanotte questionnaire with 5-point scale responses, measures are adapted from a published, untitled series of items created by Vandelanotte et al for evaluation of technology-mediated health promotion content. Acceptability and feasibility of 3 components on a 5-point Likert scale-activity monitor (7-item), program team (6-item), and the program itself (15-item). Ranged: 1 (strongly disagree) to 5 (strongly agree). The higher the score means that it is more acceptable and feasible.
