Self-Acceptance and Supportive Accountability for Active Living Among Adults Receiving Chemotherapy

Semi-structured interviews will be used to assess participants' overall experience and their perceptions of the usability, usefulness, and enjoyability of the intervention.

Face valid questions will be used to determine whether participants found the interventions easy to use. The face valid questions consists of five 7-point Likert-type items. Responses range from "Not At All Easy" (scored as 1) to "Very Easy" (scored as 7). Higher scores reflect greater ease of use.

Face valid questions will be used to determine whether participants found the interventions useful. The face valid questions consists of five 7-point Likert-type items. Responses range from "Not At All Useful" (scored as 1) to "Very Useful" (scored as 7). Higher scores reflect greater perceived usefulness.

Face valid questions will be used to assess the enjoyability of the interventions in this study. The face valid questions consists of five 7-point Likert-type items. Responses range from "Not At All Enjoyable" (scored as 1) to "Very Enjoyable" (scored as 7). Higher scores reflect greater enjoyability.

The interest/enjoyment subscale of the Intrinsic Motivation Inventory (IMIe) will be used to assess the enjoyability of the interventions in this study. The IMIe sub-scale consists of seven 7-point Likert-type items. Responses range from "Not At All True" (scored as 1) to "Very True" (scored as 7). Higher scores reflect greater enjoyability.

We will assess program feasibility via measurements of study retention. We will compute what percentage of enrolled participant complete post-intervention data collection procedures.

We will assess program feasibility via measurements of intervention adherence. We will compute what percentage of participants engage with at least 75% of the intervention modules.

We will assess the feasibility of assessing gene expression in the present context by assessing what percentage of enrolled participants provide analyzable data in optional post-intervention blood draws.

A modified Godin Leisure-Time Exercise Questionnaire will be used to assess participants' physical activity patterns. This self-report measure assesses the number of minutes of strenuous-, moderate-, and light-intensity exercise in a typical week (continuous). Higher scores are favorable, reflecting more aerobic physical activity. An additional item will be included that assesses the number of bouts of muscle-strengthening exercise in a typical week (0-7). Higher scores are favorable, reflecting more muscle strengthening physical activity. We will also gather data provided by consumer-grade, wearable physical activity trackers (Fitbit Charge series or similar).

The Subjective Vitality Scale (SVS) will be used to will be used to assess participants' feelings of vitality. The SVS consists of seven 7-point Likert-type items. Responses range from "Not At All True" (scored as 1) to "Very True" (scored as 7). Higher scores reflect greater enjoyability.

The Meaning Awareness Scale (MAS) will be used to assess meaning salience. The MAS consists of six 7-point Likert-type items. Responses range from "Very Rarely" (scored as 1) to "Very Often" (scored as 7). Higher scores reflect greater meaning salience.

The Personalized Psychological Flexibility Index (PPFI) will be used to assess psychological flexibility. The PPFI consists of sixteen 7-point Likert-type items. Responses range from "Strongly Disagree" (scored as 1) to "Strongly Agree" (scored as 7). Higher scores reflect greater psychological flexibility.

The Behavioral Regulation for Exercise Questionnaire-4 (BREQ-4) will be used to assess physical activity motivation. The BREQ-4 consists of twenty-eight 5-point Likert-type items. Responses range from "Not True For Me" (scored as 0) to "Very True For Me" (scored as 4). It is best practice to score each of the seven subscales separately (i.e., obtain separate scores for amotivation, external regulation, introjected avoidance regulation, introjected approach regulation, identified regulation, integrated regulation, and intrinsic regulation). For each subscale, higher scores reflect greater usage of that type of regulation.

The Physical Activity Acceptance Questionnaire (PAAQ) will be used to assess physical activity acceptance. The PAAQ consists of ten 7-point Likert-type items. Responses range from "Never True" (scored as 1) to "Always True" (scored as 7). It is best practice to score each of the two subscales separately (i.e., obtain separate scores for cognitive acceptance and behavioral commitment). For each subscale, higher scores reflect greater acceptance/commitment.

The Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29+2 Profile v2.1) will be used to assess health-related quality of life. The PROMIS-29+2 Profile v2.1 consists of thirty-one items spanning nine subscales (i.e., physical function, anxiety, depressive symptoms, fatigue, sleep disturbance, ability to participate in social roles and activities, pain interference, cognition, and pain intensity). The physical function subscale has 4 items with 5-point Likert-type responses (e.g., ranging from "Unable To Do" (scored as 1) to "Without Any Difficulty" (scored as 5). Higher scores for physical function are favorable.
