Slip Buddy App for Weight Management: Randomized Feasibility Trial of a Dietary Lapse Tracking App

Background Although calorie tracking is one of the strongest predictors of weight loss in behavioral weight loss interventions, low rates of adherence are common. Objective This study aims to examine the feasibility and acceptability of using the Slip Buddy app during a 12-week web-based weight loss program. Methods We conducted a randomized pilot trial to evaluate the feasibility and acceptability of using the Slip Buddy app compared with a popular commercial calorie tracking app during a counselor-led, web-based behavioral weight loss intervention. Adults who were overweight or obese were recruited on the web and randomized into a 12-week web-based weight loss intervention that included either the Slip Buddy app or a commercial calorie tracking app. Feasibility outcomes included retention, app use, usability, slips reported, and contextual factors reported at slips. Acceptability outcomes included ratings of how helpful, tedious, taxing, time consuming, and burdensome using the assigned app was. We described weight change from baseline to 12 weeks in both groups as an exploratory outcome. Participants using the Slip Buddy app provided feedback on how to improve it during the postintervention focus groups. Results A total of 75% (48/64) of the participants were female and, on average, 39.8 (SD 11.0) years old with a mean BMI of 34.2 (SD 4.9) kg/m2. Retention was high in both conditions, with 97% (31/32) retained in the Slip Buddy condition and 94% (30/32) retained in the calorie tracking condition. On average, participants used the Slip Buddy app on 53.8% (SD 31.3%) of days, which was not significantly different from those using the calorie tracking app (mean 57.5%, SD 28.4% of days), and participants who recorded slips (30/32, 94%) logged on average 17.9 (SD 14.4) slips in 12 weeks. The most common slips occurred during snack times (220/538, 40.9%). Slips most often occurred at home (297/538, 55.2%), while working (153/538, 28.4%), while socializing (130/538, 24.2%), or during screen time (123/538, 22.9%). The conditions did not differ in participants’ ratings of how their assigned app was tedious, taxing, or time consuming (all values of P>.05), but the calorie tracking condition gave their app higher helpfulness and usability ratings (all values of P<.05). Technical issues were the most common type of negative feedback, whereas simplicity was the most common type of positive feedback. Weight losses of ≥5% of baseline weight were achieved by 31% (10/32) of Slip Buddy participants and 34% (11/32) of calorie tracking participants. Conclusions Self-monitoring of dietary lapses and the contextual factors associated with them may be an alternative for people who do not prefer calorie tracking. Future research should examine patient characteristics associated with adherence to different forms of dietary self-monitoring.

Our second aim was to describe the total number of slips reported and the contextual factors reported at slips including location of slips, type of eating episode (e.g., lunch, snack), stress, and hunger/satiety. This aim was descriptive in nature. Our third aim was to assess the usability, acceptability, and burden of Slip Buddy App quantitatively and via qualitative interviews where participants shared what they liked and disliked about Slip Buddy App and features they would like added. Like aim 1, we tested whether the commercial app is signi cantly superior in usability, acceptability, and burden which would signal areas for further modi cation to Slip Buddy before proceeding to an e cacy trial. Our fourth aim was to describe percent weight loss from baseline to 12 weeks in both groups, including the proportion of participants who lost clinically signi cant weight. This aim is exploratory because only a fully powered e cacy trial could address this question and that is premature during this developmental stage.

" "As the nature of diet tracking differed between the two treatment conditions, how we assessed app use also differed. For participants in the Slip Buddy condition, we intended to categorize participants as having used the Slip Buddy App for a given day if (1) backend data from the app revealed at least one slip was recorded or check-in completed (optional), or (2) in the absence of slips, the participants responded to the end-of-day check-in saying that they did not have any slips that day. Staff reviewed the data in the Slip Buddy database server (i.e., backend data) and recorded the number of days each week each participant used the app (e.g., either recorded a slip or responded to a noti cation or check-in reporting that they experienced no slips). However, some participants reported that they did not see or receive the end-of-day check-in noti cations from the app which we determined was related to the authentication token on the phone expiring periodically. The endof-the-day noti cation gives the participant the opportunity to con rm that no slips occurred if none had been recorded thus far. Without the noti cation we cannot distinguish between a day in which the participant did not track slips and a day in which no slips occurred. For this reason, backend data would be an underestimation of app use. Because failure can sometimes happen while transmitting app data to the remote database server, we also collected self-report app use data by emailing participants each week a single item asking them how many days they used the app to track slips that week. Self-report data was available for 74% (n=282/379) of weeks across all participants (counting only 7 weeks for the participant who withdrew due to pregnancy). Because 26% of selfreport data was missing and backend data was incomplete by an unknown amount, we leveraged both forms of data to measure app use. We used the larger of the two values for two reasons: 1) when self-report data is higher than backend data it could correct for the underestimation bias of backend data, and 2) when backend data is higher than self-report it could correct for recall bias from selfreport. The weakness is that we don't have a way to correct for recall bias from self-report that overestimates use which surely exists to some extent. Self-report data were used on 58% of total weeks (220 weeks) and backend data were used 27% of weeks (104 weeks) which includes the 7 weeks backend was higher than self-report and the 97 weeks in which self-report was missing. On the remaining 15% of weeks (55 weeks) self-report and backend were the same so that value was used. Even though there is no way to correct for possible overestimations via selfreport, on 26% of weeks (97 weeks) only backend data were available which would be an underestimate for those weeks."

Participants randomized to the Slip Buddy condition were provided the Slip Buddy App, and participants randomized to the Calorie Tracking condition were instructed to install the free, commercially-available MyFitnessPal app. Each group had a different counselor who was either a registered dietitian or a clinical psychologist and each was trained in the app assigned to their respective conditions. As in our previous work, [17,18] the lifestyle intervention was delivered via twice daily posts and each week's content was based on the corresponding module of the DPP. The DPP assigns participants the goals of 1) calorie tracking to achieve a calorie goal based on amount needed to lose 1-2 pounds per week (modi ed to weekly slip tracking in the Slip Buddy condition), 2) developing a healthy diet consistent with the American Heart Association guidelines, 3) engaging in 150-300 minutes per week of moderate intensity exercise, 4) developing a strength training regimen consistent with the National Guidelines for Physical Activity, and 5) losing 1-2 pounds per week. Goal setting occurred on Monday mornings when the counselor asked participants to set 2-3 diet and exercise goals and gave speci c suggestions based on the topic of the week (e.g., self-monitoring, reduce added sugar, add 15 minutes of exercise) to help participants progress toward their weight loss goal. On Fridays, the counselor put up a weigh-in post asking participants to reply with their weight change in pounds (e.g., lost 1 pound) for the week. This ensures participants are weighing themselves weekly and allows an opportunity for problem solving for those not losing weight. Goal accountability occurred every Sunday when the counselor asked participants to report how they did on their weekly goals. In between these key posts were posts related to the topic of the week (e.g., nutrition, making time for exercise). On remaining days the counselor posted discussion threads relating to that week's module. Each week staff produced weight and engagement reports for the counselors so they could identify participants who hadn't engaged in the past week and/or who were not losing weight and attempt to engage them in the group by tagging them in posts. Tagging a participant in a post results in their receiving a noti cation on their Facebook account that when clicked leads them to the post in which they were tagged. In our previous studies, this Facebook-delivered weight loss intervention has produced mean weight losses at 12 weeks ranging from 2 6% 4  has produced mean weight losses at 12 weeks ranging from 2.6%-4.8%. [19][20] Slip Buddy App As described above, we developed Slip Buddy App which assists users to track non-homeostatic eating and the contextual factors surrounding it ( Figure 1). [16] Because "non-homeostatic eating" is scienti c jargon, the app refers to these episodes as "slips." Participants were instructed to hit an "Oops!" button each time they have a diet slip, de ned as any eating that resulted in consuming (food or drink) more than planned at a meal or between meals, eating in the absence of hunger (e.g., ate a donut someone brought to work), emotional eating, eating past the point of fullness, or an unhealthy food choice (e.g., stopped for fast food instead of cooking). The de nition of a slip appeared near the "Oops!" button as a reminder to the user. To increase awareness of when slips are most likely to occur, the app passively collected the date and time for each slip reported. For each slip, participants were asked to rate their stress and hunger/satiety on 0-10 scales, to describe the context of the slip from drop-down menus, including type of eating episode (e.g., lunch, snack) and activity during the episode (e.g., working, socializing, watching TV). They were also asked to type in their location (e.g., restaurant), food consumed, and any other notable details they wanted to remember later in open text boxes. A check-in tab asks participants to report weight, hours slept last night, stress, and hunger in the morning and stress and hunger in the afternoon, but unlike in our rst pilot study, we removed the noti cations for the morning and afternoon check-ins to keep noti cations to a minimum. The only noti cation occurred at the end of the day, asking participants if they missed entering any slips for the day and if so, to record the missed slips.
The data collected by the app was securely sent to the remote Slip Buddy database server in addition to being recorded in the local database in participants' mobile phones. The history tab showed participants their past slip entries so they can look for patterns in contextual factors such as stress ratings, hunger level, activities, and/or location (see Figure 1). During the group each week, the counselor instructed participants to view their slip history from the previous week and use that information to set goals around how to avoid and/or manage cues associated with past slips. For example, if most slips occurred while watching TV in the evening, they could set the goals of planning healthy snacks at this time or reducing TV time. Participants were urged to use the app to learn when and why they slip and to reduce their slips over time toward the goal of losing subitem not at all important 1 2 3 4 5 essential expenditure via exercise in an effort to stay within that goal. Participants were asked to enter everything they eat and drink throughout each day and all of their structured physical activity. They were asked to stay within their calorie goal to facilitate a weight loss of 1-2 pounds per week."

The de nition of a slip appeared near the "Oops!" button as a reminder to the user. To increase awareness of when slips are most likely to occur, the app passively collected the date and time for each slip reported. For each slip, participants were asked to rate their stress and hunger/satiety on 0-10 scales, to describe the context of the slip from drop-down menus, including type of eating episode (e.g., lunch, snack) and activity during the episode (e.g., working, socializing, watching TV). They were also asked to type in their location (e.g., restaurant), food consumed, and any other notable details they wanted to remember later in open text boxes.

App Use As the nature of diet tracking differed between the two treatment conditions, how we assessed app use also differed. For participants in the Slip Buddy condition, we intended to categorize participants as having used the Slip Buddy App for a given day if (1) backend data from the app revealed at least one slip was recorded or check-in completed (optional), or (2) in the absence of slips, the participants responded to the end-of-day check-in saying that they did not have any slips that day. Staff reviewed the data in the Slip Buddy database server (i.e., backend data) and recorded the number of days each week each participant used the app (e.g., either recorded a slip or responded to a noti cation or check-in reporting that they experienced no slips). However, some participants reported that they did not see or receive the end-of-day check-in noti cations from the app which we determined was related to the authentication token on the phone expiring periodically. The endof-the-day noti cation gives the participant the opportunity to con rm that no slips occurred if none had been recorded thus far. Without the noti cation we cannot distinguish between a day in which the participant did not track slips and a day in which no slips occurred. For this reason, backend data would be an underestimation of app use. Because failure can sometimes happen while transmitting app data to the remote database server, we also collected self-report app use data by emailing participants each week a single item asking them how many days they used the app to track slips that week. Self-report data was available for 74% (n=282/379) of weeks across all participants (counting only 7 weeks for the participant who withdrew due to pregnancy). Because 26% of selfreport data was missing and backend data was incomplete by an unknown amount, we leveraged both forms of data to measure app use. We used the larger of the two values for two reasons: 1) when self-report data is higher than backend data it could correct for the underestimation bias of backend data, and 2) when backend data is higher than self-report it could correct for recall bias from selfreport. The weakness is that we don't have a way to correct for recall bias from self-report that overestimates use which surely exists to some extent. Self-report data were used on 58% of total weeks (220 weeks) and backend data were used 27% of weeks (104 weeks) which includes the 7 weeks backend was higher than self report and the 97 weeks in which self report was missing On the remaining self-report and the 97 weeks in which self-report was missing. On the remaining 15% of weeks (55 weeks) self-report and backend were the same so that value was used. Even though there is no way to correct for possible overestimations via selfreport, on 26% of weeks (97 weeks) only backend data were available which would be an underestimate for those weeks. For participants in the Calorie Tracking condition, research staff reviewed MyFitnessPal records and we coded a "complete day" of calorie tracking any day in which participants tracked 2+ meals and 800+ kcal/day, as has been done elsewhere. [21,22] As participants in the Calorie Tracking condition were instructed to track all food and beverage intake, we only included "complete days" of tracking in our calculations of MyFitnessPal use.
Using the above de nitions, we calculated the number and percentage of days participants in each treatment condition used their assigned app over the 12-week intervention. Because the Slip Buddy App was down for two days in week 3, participants in this condition could have only used the app on a maximum of 82 days versus the 84 possible days for participants in the Calorie Tracking condition.
We also categorized participants in both conditions as to whether they used their assigned app at least once over the 12-week intervention, and whether they used their assigned app during week 12 as a measure of sustained engagement. Two participants were withdrawn or dropped out of the intervention due to incident pregnancy. For these women, use was not assessed after they were no longer in the intervention (after week 7 for the Slip Buddy participant who became pregnant, after week 2 for the Calorie Tracking participant), but instead the calculation of percent days the app was used only counted days they were in the intervention. Slip Buddy App Data (Slip Buddy participants only)

Slips Reported
Backend data from the app was used to describe the number of slips reported for each participant during the intervention period and contextual factors related to slips.

Location of Slip
Participants were asked to note via free response where they were when the slip occurred. The rst author collapsed free responses into categories that included work, home, other person's house, restaurant/bar, at an event (e.g., football game), in the car, or at the gym.

Nature of Eating Episode
Participants also indicated the nature of the eating episode in which the slip occurred which included the choices breakfast, lunch, dinner, dessert, snack, or alcohol. Alcohol was included to capture drinking episodes that happen outside of the context of meals or snacks and to prompt participants to think of excess alcohol intake as a dietary slip. Activity during Slip Participants also indicated what they were doing from a drop-down menu of domestic activities (e.g., chores), working/studying (e.g., employment, school), socializing, screen time, or commuting.

Stress and Hunger/Fullness Ratings of Slips
When they entered a slip, participants rated how much stress they were experiencing before their slip on a 0 to 10 scale where 0 indicates no stress and 10 indicates extreme stress. Stress scores of 5 and above were considered moderate to high stress, whereas stress ratings of less than 5 were considered low stress. Participants also rated how hungry or full they felt before they slipped on a 0-10 scale where 0 indicates extremely hungry, 5 indicates comfortably full, and 10 indicates stuffed, i.e., uncomfortably full.

My Fitness Pal Data (Calorie Tracking participants only)
Participants were asked to record their diet every day for 12-weeks. This data was extracted from MyFitnessPal and coded for analysis. The rst level of coding included recording each day that the participant entered at least one item. The second level was extracting the number of eating episodes and calories each day.

Usability
The System Usability Scale (SUS)[23] was used at 12-weeks to assess the usability of Slip Buddy App. The SUS is a 10-item 5-point Likert scale questionnaire regarding human-computer interaction. For one participant who only answered 9 of the 10 questions, we used their mean of those 9 items to impute a response to the tenth item. A SUS score above 70 is considered acceptable and above average while a score above 85 is considered excellent.
[24] Moreover, when users rate a system with a SUS score of 82 (+-5), they tend to be "promoters" of the system, meaning likely to recommend it to a friend. [25] Acceptability At 12-weeks, participants in both conditions rated the helpfulness and ease of use of their assigned app (response options: strongly disagree, disagree, neutral, agree, strongly agree). We dichotomized responses as strongly agree/agree vs strongly disagree/disagree/neutral. Because Slip Buddy App is exclusively focused on diet, unlike calorie tracking apps which address both diet and exercise, we included a question at follow-up asking participants to rate whether a feature that would allow them to track exercise slips (i.e., times when they had planned to exercise but did not follow through) would increase the effectiveness of Slip Buddy App.
Acceptability was also evaluated in post-intervention focus groups via two questions, "what did you like most about Slip Buddy App and why?" and "what did you like least about Slip Buddy App and why?" During the intervention, participants started a discussion about the possibility of Slip Buddy App having a feature that would allow people to track when they were tempted to slip but resisted that temptation. Given the enthusiasm for the idea, we added a question to the focus subitem not at all important 1 2 3 4 5 essential group script asking participants about the extent to which they would like to track temptations that did not turn into slips.

Burden
At 12-weeks, participants in both conditions rated how burdensome it was to use their assigned app on a scale of 0-100 with 0 being not at all burdensome and 100 being very burdensome. Participants rated how much they agreed that the app was time consuming, taxing, and tedious (response options: strongly disagree, disagree, neutral, agree, strongly agree). We dichotomized responses as strongly agree/agree vs strongly disagree/disagree/neutral.

For variables that were normally distributed, we described distributions using mean and standard deviation (M[SD]), and for variables that were not normally distributed, we described distributions using median and interquartile range (IQR). We compared use, retention, usability, and acceptability by treatment condition using t-tests, chi-squared tests, or Fisher's exact tests as appropriate. We compared treatment conditions on app burden using a Wilcoxon rank-sum test. Insu cient retention, acceptability, and use was assumed if the calorie tracking condition showed a statistically signi cant advantage relative to Slip Buddy. Statistical tests were not used to compare groups on weight loss because this pilot study was not powered for weight loss e cacy thus it is not appropriate to perform such tests, as discussed elsewhere.
[27] We took an intentto-treat approach to describing weight change. Two participants (one in each condition) became pregnant during the study. We used latest available prepregnancy weights (from weeks 2 and 3, respectively) from their study scales as their follow-up values. Three participants did not provide weight at follow-up. We also used their latest weight from their study scales (weeks 6, 9, and 10, respectively) as their follow-up values.

Always clearly define "use" of the intervention.   Table 2). The nature of the eating episode most likely to be reported as a slip was a snack (n=220; 40.9%), followed by dinner (n=102; 19.0%), dessert (n=77; 14.3%), and lunch (n=60; 11.2%; Table 2). Activities engaged in when the slip occurred was split over work or studying (n=153; 28.4%), socializing (n=131; 24.2%), screen time (n=123; 22.9%), and domestic activities (n=112; 20.8%); a small percent of slips occurred while commuting (n=20; 3.7%; Table 2). The median stress rating during slips was 4 (inter-quartile range: 2-5). The median hunger/fullness rating during slips was 4 (inter-quartile range: 2-5). One-fth of slips (n=106; 20%) occurred when both stress and hunger were low, and another 20% (n=105) occurred when both stress and hunger were high.  Table 3).

Clear selection
The majority of both Slip Buddy (n=24; 77%) and Calorie Tracking participants (n=26; 87%) agreed or strongly agreed that using their respective app was easy (Χ2 (1,N=61)=0.8820; p=0.3674; Table 3). Two-thirds of Slip Buddy participants (n=21; 68%) agreed or strongly agreed that adding the ability to track exercise slips would be helpful.

Burden
On a scale of 0 to 100, median burden rating for participants in the Slip Buddy condition was 30 (IQR: 15-50) and the median burden rating for participants in the Calorie Tracking condition was 45 (IQR: 10-60; U=949.5000, p=0.7829). The proportion of participants who agreed or strongly agreed that using their assigned app was tedious or taxing did not differ by treatment condition (Table 3) how to use when no slips (n=7; 21%), did not nd stress ratings relevant (n=5; 15%), focus on slips is too negative (n=4; 12%), was not sure what to count as a slip (n=4; 12%), did not include diet instruction (n=4; 12%), slip history screen was not as informative as it could be (n=1; 3%). For the nal question regarding their thoughts on a feature that would allow them to track when they were tempted but did not slip, 75% (n=21) said they would be enthusiastic about this feature. The remainder said they worried it would add too much burden.

Weight Change
Over 12 weeks, participants randomized to the Slip Buddy condition had average weight loss of -6.5 pounds (SD=9.7) or 3.0% (SD: 4.5%) of their baseline weight and participants randomized to the Calorie Tracking condition had weight loss of -7.5 pounds (SD=10.7) or 3.6% (SD: 4.9%) of their baseline weight (Table 4). In terms of clinically signi cant weight loss, 31% and 34% of participants randomized to the Slip Buddy and Calorie Tracking conditions, respectively, achieved 5% or greater weight loss, and 47% and 47%, respectively, achieved 3% or greater weight loss (Table 4). In a secondary analysis assuming no weight loss for the 2 participants who became pregnant and the 3 participants lost to follow-up (i.e., baseline observation carried forward approach), weight losses were on average -6.1 (SD: 9.8) pounds and -2.8% (SD: 4.6%) among Slip Buddy participants and on average -7.1 (SD: 10.8) pounds and -3.4% (SD: 5.0%) among Calorie Tracking participants, with 31% and 34% of participants, respectively, losing 5% or greater weight loss from baseline, and 48% and 47%, respectively, losing 3% or greater weight loss from baseline. In a secondary analysis of just the 59 participants who provided weight at follow-up and were not pregnant (n=30 Slip Buddy, n=29 Calorie Tracking), weight losses were on average -6.5 (SD: 10.0) pounds and -3.0% (SD: 4.7%) among Slip Buddy participants and on average -7.9 (SD: 11.1) pounds and -3.8% (SD: 5.1%) among Calorie Tracking participants, with 33% (n=11) and 38% (n=12) of participants, respectively, losing 5% or greater weight loss from baseline and 44% (n=14) and 44% (n=14), respectively, losing 3% or greater weight loss. subitem not at all important 1 2 3 4 5 essential 17a) For each primary and secondary outcome, results for each group, and the estimated effect size and its precision (such as 95% confidence interval)

18-i) Subgroup analysis of comparing only users
A subgroup analysis of comparing only users is not uncommon in ehealth trials, but if done, it must be stressed that this is a self-selected sample and no longer an unbiased sample from a randomized trial (see 16-iii).

20-i) Typical limitations in ehealth trials
Typical limitations in ehealth trials: Participants in ehealth trials are rarely blinded. Ehealth trials often look at a multiplicity of outcomes, increasing risk for a Type I error. Discuss biases due to non-use of the intervention/usability issues, biases through informed consent procedures, unexpected events. 21) Generalisability (external validity, applicability) of the trial findings NPT: External validity of the trial findings according to the intervention, comparators, patients, and care providers or centers involved in the trial Does your paper address subitem 20-i? * Copy and paste relevant sections from the manuscript (include quotes in quotation marks "like this" to indicate direct quotes from your manuscript), or elaborate on this item by providing additional information not in the ms, or briefly explain why the item is not applicable/relevant for your study This study has limitations. First, the sample size was not large enough to compare the two conditions on weight loss. However, the purpose of this work was to evaluate feasibility and acceptability of the Slip Buddy App using a user-informed process to guide improvements to the technology prior to conducting a fully powered randomized trial. We chose a 12-week intervention length to allow us to gain user insights after a prolonged period of use, but this study does not provide information on tracking habits over longer periods of time, such as whether slip tracking decreases over time as participants learn their triggers and slip less.

Clear selection
Another limitation is that our ability to measure app use via backend data was hampered by the fact that some participants did not see or receive end-of-the-day noti cations that when clicked would indicate whether no slip entries meant a slipfree day or non-use. For this reason, we had to rely on self-report use data which is prone to biases due to forgetting or social desirability. This can be ameliorated in the next version, and the addition of temptation and exercise slip tracking will give the user more to do each day with the app even in the absence of slips. Another limitation is that the Slip Buddy app was not operating for two days which could have affected use in subsequent days to the extent that participants were frustrated by this. Because it is a newly developed app, bugs and crashes are more common relative to commercial apps that have been around for many years and this will certainly impact usability ratings. Finally, a limitation is that the sample overrepresented non-Hispanic White women (83% of our sample, n=53). In future research, recruitment will need to limit enrollment of non-Hispanic white women, the population segment that too often comprises the majority of weight loss trial samples, [37] to no more than the proportion of the population they represent.
