Abstract: (224 Views)
Background: Although cognitive bias modification intervention and cognitive-behavioral therapy are two effective methods for reducing food cravings in obese people, to date, no randomized controlled trials compare the effectiveness of internet-based cognitive-behavioral intervention and cognitive bias modification on food cravings in people requesting small gastric bypass surgery.
Aims: This study aimed to examine the effectiveness of a cognitive bias modification compared to internet-based cognitive behavioral therapy for food cravings.
Methods: This study was a quasi-experimental study with a series of pretest-posttest designs with a control group and a follow-up of 2 months. The statistical population consisted of people who wanted gastric sleeve surgery in 2023, were 18 months post-surgery, and lived in Isfahan. From this group, 45 participants were chosen at random into three groups: Internet-based cognitive behavioral therapy, cognitive bias modification, and control (15 participants per group) using purposive sampling. Over six weeks, participants in the intervention groups attended 42 sessions, while the control group did not receive any therapeutic intervention. Participants were assessed using the Food Craving Questionnaire (Cepeda-Benito et al., 2000) before and after the intervention sessions and two months after the intervention. Data were analyzed using SPSS.24 software and mixed analysis of variance with repeated measures.
Results: The findings showed that both cognitive bias modification (CBM) and internet-based cognitive-behavioral therapy (CBT) could have a positive impact on reducing food cravings and its components (p< 0.05). In addition, cognitive bias modification demonstrated significantly higher effectiveness than internet-based cognitive behavioral therapy in the components of lack of control, preoccupation with food, emotional craving, feeling of guilt, and total food craving (p< 0.05).
Conclusion: Considering the effectiveness of cognitive bias moderation training and cognitive-behavioral therapy in reducing food cravings, it is suggested that these interventions be used along with other evidence-based pharmacological and therapeutic interventions as psychological intervention to change their beliefs and attitudes toward cravings.
