Partner- and planning-based interventions to reduce fat consumption: randomized controlled trial.
Objective: The research tested the efficacy of partner- and planning-based interventions to reduce dietary fat intake over a 6-month period.Design: Randomized controlled, blinded, parallel trial.Methods: A computer randomization feature was used to allocate council employees (N = 427, of which 393 c...

Outcome measures were comprised of validated self-report measures of dietary fat intake (saturated fat intake, fat intake, ratio of 'good' fats to 'bad' fats); psychosocial mediators (enjoyment, intention, self-efficacy, social influence, partner support); weight and waist size (baseline and 6 months only).Results: Data from 393 participants were analysed in accordance with intention-to-treat analyses. All intervention groups reported greater reductions in fat intake than the control group at 3 months. The partner-based groups increased the ratio of 'good' fats to 'bad' fats at 3 and 6 months and lost more inches on their waist, versus the non-partner groups. The impacts of the partner-based manipulations on outcomes were partially mediated by greater perceived social influences, partner support, and enjoyment of avoiding high-fat foods. The partner-based interventions also increased intention and self-efficacy. However, the effects in this study were typically small and generally marginally significant.Conclusions: Partner-based interventions had some positive benefits on dietary-related outcomes at 3 and 6 months. Support for implementation intentions was more limited. pubtype: Academic Journal doctype: research randomized controlled trial Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
