Brief summary

The primary objective of this study is to experimentally test the momentary and more distal psychological effects of daily self weighing as compared to an active control group.

Detailed description

Two significant public health problems, obesity and eating disorders, are prevalent during emerging adulthood, a unique stage of life between ages 18 and 25. Over half of emerging adults experience weight gain and/or disordered eating (e.g. overly restrictive dieting, binge eating); both of which contribute to obesity. Because many emerging adults attend college, the college community represents a viable population for implementing interventions to prevent weight gain, while not triggering disordered eating. A promising strategy for preventing weight gain during college is daily self-weighing, an example of behavioral self-monitoring, an evidence-based strategy for weight control. Self-monitoring is fundamental to behavior change: feedback allows the user to evaluate progress in relation to a goal and modify behavior. Despite self-monitoring being recommended, some evidence suggests that self-monitoring strategies, self-weighing in particular, may have unintended psychological consequences; the concern being that negative mood states could precipitate disordered eating. Alternatively, other evidence suggests positive psychological outcomes related to daily self-weighing in young adults. Technological advances have allowed for users to track personal health information in real time. Given that 60% of U.S. adults track weight, diet, or exercise, and 92% of adults aged 18-34 own a smartphone, electronic self-monitoring is feasible in this population. What is less known is individuals' psychological and behavioral response to self-monitoring. This original, important study will contribute to the fields of obesity and eating disorders and experimentally test the psychological effects of this daily weight-control intervention.

Interventions

Participants are provided with a wifi-enabled scale and asked to weigh themselves daily, first thing in the morning.

BEHAVIORALdaily temperature-taking

Participants are provided with a wifi-enabled thermometer and asked to take their temperature daily, first thing in the morning.

Design outcomes

Primary

MeasureTime frameDescription
psychological response to daily self-weighing3 Months1. Daily self-weighing will result in significantly greater reactivity than daily-temperature-taking 2. There will be no significance in mood ratings between daily self-weighing and daily temperature-taking groups for EMA recordings later in the day. 3. The daily self-weighing group will report significantly more weight control behaviors at the end of the day as compared to the daily temperature-taking group.

Secondary

MeasureTime frameDescription
Identify moderators of response to daily self-weighing in a college-aged female population3 Months1. Participants with lower baseline dietary restraint scores will experience significantly greater success in preventing weight gain over 3 months in response to daily self-weighing as compared to daily temperature-taking, in comparison to those with higher baseline dietary restraint scores 2. Participants with higher baseline body satisfaction, lower body consciousness, and higher-self esteem will have significantly more favorable reactions to daily self-weighing, both in terms of momentary mood and prevention of weight gain over 3 months 3. Baseline weight status will moderate the effectiveness of daily self-weighing as a weight gain prevention tool, such that it will work significantly better for overweight patients.
