UMIN ID: UMIN000054047

Registered date:03/04/2024

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Obesity
• Date of first enrollment: 2024/04/03
• Target sample size: 60
• Countries of recruitment: Japan
• Study type: Interventional

Intervention(s)

Intervention group (Attention bias modification training group: distracting attention from food)
Placebo group (random attention to food/neutral objects)
Control group (no training)

Outcome(s)

• Primary Outcome: (1) Self-assessment scale (questionnaire) 1. Hunger and Satiety Scale 2. face items Gender, age, height, weight, tendency of eating behavior, etc. 3. Japanese version of the DEBQ scale 4. PANAS scale (Japanese translation of Watson et al., 1988) (2) Visual probe task In this task to measure attentional bias, two stimulus images are presented, one on each side of the screen, for 2 seconds after a 1-second presentation of the gazing point (+) in the center of the PC screen. The subject is then asked to press the button on the same side as the point displayed on either side of the screen. The stimulus image is a high-fat food (e.g., pizza) and the comparison image is a musical instrument. The subject's eye movements (gazing time) are also measured. The eye movements are measured using Tobbi's Pro Nano eye tracker. (3) Modified version of the visual probe task In this task for correcting attentional bias, the gazing point (+) in the center of the PC screen is presented for 0.5 seconds, and then two stimulus images are presented for 2 seconds, one on each side of the screen. The intervention group then has a point (*) appear at the location of the neutral image (instrument) on each trial to divert attention away from the high-lipid food image (e.g., pizza). For the placebo group, the position of the dot (*) will be randomized on a trial-by-trial basis. The subjects' eye movements (gazing time) will be measured during the trials. The eye movements will be measured using Tobii's Pro Nano eye tracker.
