Using an API to Commercialize an Evidence-Based Weight Loss Intervention

2016-06-26 20:34:25 | BioPortfolio

Summary

This study will test the effectiveness of a mobile application that uses an Application Program Interface (API) to distribute evidence-based weight loss interventions. Half of the participants will receive this API-based application, and the other half of the participants will use a non API-based application.

Description

The purpose of this study is to test a weight loss app that uses an API to disseminate an evidence-based weight loss intervention. The investigators hypothesize that, over the course of 12 months, participants using the Leaner app will have lost more weight than those in the attention control group.

Participants (n=206) will be randomly assigned to use either the intervention app (intervention arm; n=103) or a weight loss app of their choosing (attention control arm; n=103) for 12 months. Assessments will take place at baseline, and 3, 6, and 12 months.

Statistical analysis: A linear mixed modeling approach will be used to test the hypothesis. Observed weight vs. time plots will be analyzed for all participants to discern general trends in weight change. The model will include an intervention effect, a time effect, an intervention by time interaction, and a random intercept.

In exploratory analysis, investigators will examine weight change across subgroups of interest; investigators will add the subgroup variable and its interaction with the intervention indicator to the primary model. All analyses will be evaluated at the 0.05 significance level.

Medical and Biotech [MESH] Definitions

The relative amount by which the average fitness of a POPULATION is lowered, due to the presence of GENES that decrease survival, compared to the GENOTYPE with maximum or optimal fitness. (From Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)

Decrease in existing BODY WEIGHT.

A status with BODY WEIGHT that is above certain standard of acceptable or desirable weight. In the scale of BODY MASS INDEX, overweight is defined as having a BMI of 25.0-29.9 kg/m2. Overweight may or may not be due to increases in body fat (ADIPOSE TISSUE), hence overweight does not equal "over fat".

An eating disorder that is characterized by the lack or loss of APPETITE, known as ANOREXIA. Other features include excess fear of becoming OVERWEIGHT; BODY IMAGE disturbance; significant WEIGHT LOSS; refusal to maintain minimal normal weight; and AMENORRHEA. This disorder occurs most frequently in adolescent females. (APA, Thesaurus of Psychological Index Terms, 1994)

A scale comprising 18 symptom constructs chosen to represent relatively independent dimensions of manifest psychopathology. The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses. (From Hersen, M. and Bellack, A.S., Dictionary of Behavioral Assessment Techniques, p. 87)
