Practicing Interoceptive Sensitivity as a Couple: A Mixed-Methods Acceptance Analysis of a Dyadic vs. Single Pilot...

Area of Science:

• Behavioral Science
• Health Psychology
• Nutrition Science

Background:

• Interoceptive sensitivity (IS) training may enhance intuitive eating (IE).
• Dyadic interventions involving couples are increasingly explored for health behaviors.
• Older adults (50+) present unique considerations for health behavior change interventions.

Purpose of the Study:

• To assess the acceptance and feasibility of dyadic interoception-based training for intuitive eating among couples aged 50+.
• To compare spousal acceptance of dyadic versus single-participant training formats.
• To identify barriers and facilitators to engaging in interoception-based intuitive eating training within a couple context.

Main Methods:

• A pilot randomized controlled trial using a mixed-methods convergence design.
• Survey data from 68 couples and focus group discussions with 4 couples were synthesized.
• Intervention included three exercises: Body Scan (BS), hunger (HU), and satiety (SA) exercises.

Main Results:

• Moderate general acceptance of the training, with a preference for the Body Scan (BS) exercise due to pleasantness and perceived benefits like improved sleep.
• Barriers included a perceived lack of usefulness and unclear training objectives.
• Spousal involvement was viewed positively, with pre-existing harmonized routines facilitating joint training.

Conclusions:

• Dyadic IS training shows potential for promoting IE in older couples.
• Future interventions should incorporate regular feedback and closer guidance to enhance understanding of IS and IE processes.
• Leveraging couples' existing routines and communication may optimize intervention effectiveness.
