N2 - Objective: Despite the promising results related to
intuitive eating, few studies have attempted to explain
the processes encouraging this adaptive eating behaviour.
The focus of the present study was on exploring
mechanisms of change in intuitive eating and weight in
acceptance and commitment therapy (ACT) interventions.
Mediation provides important information regarding the
treatment processes and theoretical models related to
specific treatment approaches. The study investigates
whether psychological flexibility, mindfulness skills and
sense of coherence mediated the interventions' effect on
intuitive eating and weight. Design: Secondary analysis
of a randomized control trial. Mediation analysis
compared two ACT interventions - face-to-face (in a
group) and mobile (individually) - with a control group
using a latent difference score model. Settings: Data
were collected in three Finnish towns. Subjects: The
participants were overweight or obese (n 219), reporting
symptoms of perceived stress. Results: The effect of the
interventions on participants' (i) BMI, (ii) intuitive
eating and its subscales, (iii) eating for physical
rather than emotional reasons and (iv) reliance on
internal hunger and satiety cues was mediated by changes
in weight-related psychological flexibility in both ACT
groups. Conclusions: These findings suggest that ACT
interventions aiming for lifestyle changes mediate the
intervention effects through the enhanced ability to
continue with valued activities even when confronted with
negative emotions and thoughts related to weight.
