Objective: The objective of this feasibility study is to address uncertainties regarding the inclusion of accelerometer-based assessment of physical activity within the Fun For Wellness online intervention among free-living adults with obesity in the United States of America. Method: The study design is a prospective, double-blind, parallel group randomized pilot trial. Discussion: Results are intended to inform the preparation of a future definitive randomized controlled trial.

Detailed Description
-----------------
Fun For Wellness is an online intervention designed to promote growth in well-being and physical activity by providing confidence-enhancing learning opportunities to participants [1]. The conceptual framework for the Fun For Wellness intervention is guided by self-efficacy theory [2]. Evidence has been provided for the efficacy of Fun For Wellness to promote self-reported physical well-being actions in free-living adults who comply with the intervention [3]. The objective of this feasibility study is to address uncertainties regarding the inclusion of accelerometer-based assessment of physical activity within the Fun For Wellness online intervention among free-living adults with obesity in the United States of America. Four specific aims will be investigated. Aim 1. To determine if accelerometer-based assessment of physical activity can be used within the Fun For Wellness intervention. Aim 2. To determine if accelerometer-based assessment of physical activity should be used within the Fun For Wellness intervention. Aim 3. To determine how to implement accelerometer-based assessment of physical activity within the Fun For Wellness intervention. Aim 4. To provide a preliminary effect size estimate for each direct effect in the conceptual model for the Fun For Wellness online intervention. Pursuit of these four specific aims is based on a general conceptual framework for feasibility and pilot studies in preparation for a future definitive randomized controlled trial [4-6]. Within this conceptual framework, a randomized pilot trial is a type of a feasibility study and a feasibility study may include a focus on the acceptability of an intervention [4-6].

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Participants will be randomly assigned to either the Fun For Wellness (FFW) group or the Usual Care (i.e., UC) group by the code programmed within the FFW website that is specified to achieve a 1:1 group (i.e., nFFW = 15, nUC = 15) assignment. Participants assigned to the UC group (i.e., UC participants) will proceed through the pre-operative weight management program provided by the center. Participants assigned to the FFW group (i.e., FFW participants) will proceed through the pre-operative program provided by the center and will be given 4 weeks (i.e., Week 3 through Week 6) of 24 hr access to the FFW online intervention during data collection for this study.

| Experimental: Fun For Wellness (FFW)<br>Participants assigned to the FFW group (i.e., FFW participants) will proceed through the pre-operative program provided by the center and will be given 4 weeks of 24 hr access to the FFW online intervention during data collection for this study. Intervention participants will: 1) watch original videos with vignettes performed by professional actors; 2) read and/or watch mini-lectures that teach skills for behavior change; 3) engage in self-reflection exercises, 4) play original interactive games related to vignettes and mini-lectures; 5) interact with other FFW users via chat room functions and; 6) watch funny narrated video clips about well-being and/or physical activity. | Behavioral: Fun For Wellness (FFW)<br>* FFW consists of videos, games, and content in the form of 152 BET I CAN challenges [1]. Behavior challenges are intended to increase a participant's capabilities to set a goal and to create positive habits. Emotion challenges are intended to increase a participant's capabilities to cope with negative emotions and to cultivate positive emotions. Thought challenges are intended to increase a participant's capabilities to challenge negative assumptions and to create a new narrative for their life. Interaction challenges are intended to increase a participant's capabilities to communicate and connect with others. Context challenges are intended to increase a participant's capabilities to read cues and to change cues in the environment. Awareness challenges are intended to increase a participant's capabilities to know herself/himself and to know the issue. Next steps challenges are intended to increase a participant's capabilities to make a plan and to stick with a plan.<br>|

| physical activity self-efficacy (leisure-related moderate sub-scale) | Physical activity self-efficacy will be measured at Wave 3 with the 48-item physical activity self-efficacy scale [11]. Responses to the six Likert-scale quantitative items intended to measure the leisure-related moderate sub-scale will be summed at Wave 3 to form a leisure-related moderate sub-scale score at Wave 3 with higher values representing greater physical activity self-efficacy (leisure-related moderate). The minimum score will be 0. The maximum score will be 24. | Week 11 | 
| Self-efficacy to regulate physical activity | Self-efficacy to regulate physical activity will be measured at Wave 3 with the 13-item self-efficacy to regulate physical activity scale [11]. Responses to the thirteen Likert-scale quantitative items will be summed at Wave 3 to form a a total self-efficacy to regulate physical activity score at Wave 3 with higher values representing greater self-efficacy to regulate physical activity. The minimum score will be 0. The maximum score will be 52. | Week 11 | 
| physical activity (Fitbit Zip) | A commercial-grade (Fitbit Zip) accelerometer will be initialized and attached to an adjustable nylon belt to measure physical activity objectively at Wave 3. Average minutes-per-day of moderate to vigorous physical activity will be determined using the Fitbit application, which uses a proprietary algorithm to estimate fairly active minutes and very active minutes. | Week 12 | 
| physical activity (Actigraph wGT3X-BT) | A research-grade (Actigraph wGT3X-BT) accelerometer will be initialized and attached to an adjustable nylon belt to measure physical activity objectively at Wave 3. Average minutes-per-day of moderate to vigorous physical activity will be calculated based on established cut points (e.g., > 1952 counts per minute). | Week 12 | 
| self-reported physical activity | Self-reported physical activity will be measured at Wave 3 with the long form of the international physical activity questionnaire [9,10]. Average minutes-per-day of moderate to vigorous physical activity will be formed by dividing the sum of the minutes per day (across one week) of minutes-per-day of moderate to vigorous physical activity in the work, transportation, domestic and gardening, and leisure domains by 7 days. | Week 12 | 
| feasibility of accelerometer-based assessment of physical activity (participation rate) | The feasibility of accelerometer-based assessment of physical activity will be assessed with participation rate at Wave 3. Participation rate at Wave 1 will be defined as the percentage of consented patients who provide usable data at Wave 3. Usable data will be defined as: (a) a log sheet with a valid start date is submitted, (b) a monitor is worn for at least 4 days (including one weekend day) with at least 10 hours of valid wear time per day, and (c) no evidence of monitor error (e.g., activity counts > 20,000 or lengthy strings of repeated activity counts). | Week 12 | 
| feasibility of accelerometer-based assessment of physical activity (retention rate) | The feasibility of accelerometer-based assessment of physical activity will be assessed with retention rate at Wave 3. Retention rate at Wave 3 will be defined as the percentage of consented patients who provide usable data at Wave 1, Wave 2, and Wave 3. Usable data will be defined as: (a) a log sheet with a valid start date is submitted, (b) a monitor is worn for at least 4 days (including one weekend day) with at least 10 hours of valid wear time per day, and (c) no evidence of monitor error (e.g., activity counts > 20,000 or lengthy strings of repeated activity counts). | Week 12 | 
| acceptability of accelerometer-based assessment of physical activity (quantitative) | The acceptability of accelerometer-based assessment of physical activity will be assessed at Wave 3 with a modified version of an unnamed questionnaire used in previous research [7,8]. The 11-item acceptability questionnaire used in this study consists of a mix of both Likert-scale quantitative (6) and open-ended qualitative (5) items. Responses to the six Likert-scale quantitative items will be summed at Wave 3 to form a total acceptability score at Wave 3 with higher values representing greater acceptability. The minimum total acceptability score at Wave 3 will be 6. The maximum total acceptability score at Wave 3 will be 23. | Week 13 | 
| acceptability of accelerometer-based assessment of physical activity (qualitative) | The acceptability of accelerometer-based assessment of physical activity will be assessed at Wave 3 with a modified version of an unnamed questionnaire used in previous research [7,8]. The 11-item acceptability questionnaire used in this study consists of a mix of both Likert-scale quantitative (6) and open-ended qualitative (5) items. Responses to the five qualitative items will be content analyzed together at Wave 3 to find conceptual themes at Wave 3 with regard to the acceptability of accelerometer-based assessment of physical activity. | Week 13 |
