Trial Outcomes & Findings for Computer-Delivered Intervention for Individuals With Obesity and Elevated Anxiety Sensitivity (NCT NCT03917901)

NCT ID: NCT03917901

Last Updated: 2024-08-26

Results Overview

The Anxiety Sensitivity Index-3 is an 18-item measured that will be used to assess sensitivity to, and fear of, the potential negative consequences of anxiety-related symptoms and sensations. Items are rated on a 5-point Likert scale, ranging from 0 (Very Little) to 4 (Very Much). Scores will be calculated by summing all items (possible range = 0 -72), with lower scores indicating a better outcome.

The Dutch Eating Behavior Questionnaire will be used to assess emotional eating. Items are rated on a 5-point Likert scale ranging from 1 (never) to 5 (very often). For the current study, the emotional eating subscale (13 items) will be used as a measure of emotional eating. The 13 items of the subscale are summed and divided by 13 to create a mean score with a range from 1-5. Lower scores on this measure indicate better outcomes.

The Eating Expectancy Inventory will be used to measure cognitive expectancies of eating. The Eating Expectancy Inventory subscale facet: eating helps manage negative affect will be used in the current study. Respondents will be asked to rate on a 7-point Likert scale the degree to which they 1 (completely disagree) to 7 (completely agree) to each item. Responses are summed for each subscale. Lower scores on the 18-item eating helps manage negative affect subscale (possible range = 18 - 126) indicate better outcomes.

Exercise self-efficacy will be assessed with a 5-item self-report assessment of one's confidence about their ability to engage in physical activity. Items are rated on a 9-point Likert-type scale that ranges from 0 (not at all confident) to 8 (extremely confident). A total score will be created by summing the 5-items with higher scores indicating a better outcome (possible range 0 - 40).
