Summary: |
Single planning interventions have been found to promote short-term dietary change. Repeated planning interventions may foster long-term effects on behavior change. It remains unknown whether there is a critical number of boosters to establish long-term maintenance of behavioral changes. This study aimed at investigating what social-cognitive variables mediate the effects of the interventions on dietary behavior change. Overall, 373 participants (n = 270 women, 72.4%; age M = 52.42, SD = 12.79) were randomly allocated to one of five groups: a control group, a single planning group, and three groups with 3, 6, or 9 weeks' repeated planning interventions. Follow-ups took place 4, 6, and 12 months after baseline. Change in fat consumption was not promoted by any of the interventions. In terms of social-cognitive variables, intentions, self-efficacy and coping planning displayed a time × group interaction, with the 9 weeks' planning group showing the most beneficial effects. Effect sizes, however, were very small. None of the tested planning interventions successfully promoted change in fat consumption across the 12 month period. This, however, could not be explained by problems with adherence to the intervention protocol. Potential explanations for this unexpected result are discussed.

Summary in another language: |
Il a été établi que des interventions de planification uniques favorisent les changements à court terme des régimes diététiques. Les interventions de planification répétées pourraient produire des effets à long terme sur le changement de comportement. On ne sait toujours pas s'il y a un nombre critique de relances pour établir le maintien à long terme de changements comportementaux. De plus, notre recherche avait pour but de trouver quelles variables sociocognitives sont médiatrices par rapport aux effets des interventions sur le changement de comportement diététique. Au total, 373 participants (n = 270 femmes, 72.4%; âge M = 52.42, ET = 12.79) ont été répartis aléatoirement dans l'un de cinq groupes : un groupe contrôle, un groupe à planification unique et trois groupes à interventions planifiées répétées de trois, six et neuf semaines. Des suivis ont eu lieu à quatre, six et 12 mois de la mesure de la ligne de base. Aucune des interventions ne faisait la promotion d'un changement dans la consommation de gras. En termes des variables sociocognitives, les intentions, l'auto-efficacité et la planification pour faire face ont donné une interaction temps par groupe, le groupe de planification de neuf semaines démontrant le plus d'effets bénéfiques. Toutefois, la grandeur des effets était très petite. Aucune des interventions planifiées n'a réussi à promouvoir un changement réussi pour la consommation de gras sur la période étudiée de 12 mois. Cela, toutefois, n'a pu être expliqué par des problèmes d'adhésion au protocole d'intervention. Nous discutons d'explications possibles de ces résultats inattendus.
