Self-efficacy and Endurance Performance: A Longitudinal Field Test of Cognitive Mediation Theory

On demanda à 123 étudiants de cours de perfectionnement, désignés au hasard, de réaliser "de leur mieux" une tâche très difficile, au but presqu' impossible à atteindre, après cinq semaines d'entraînement à effectuer une tâche spécifique en trois minutes. Une période-test de quatre semaines suivit au cours de laquelle les buts des táches que devaient réaliser les sujets et leur confiance en leur efficacité furent mesurés une fois par semaine avant chaque évaluation de performance. Construit d'après une théorie de médiation cognitive (Garland, 1985), un modèle causal fut utilisé dans lequel des buts de tâches individuelles furent soumis aux effets de la performance, notamment sur l'efficacité des sujets. L'analyse des résultats à partir des quatre tests hebdomadaires confirma les propositions du modèle.
One hundred and twenty-three students in a fitness training course were assigned at random to a "do your best," very hard, or highly improbable goal condition after five weeks of baseline training on a three-minute sit-up task. A four-week test period followed in which subjects' task goals and efficacy expectations were measured once each week prior to an assessment of their performance. Based on cognitive mediation theory (Garland, 1985), a causal model was presented in which individual task goals are proposed to influence performance through their influence on self-efficacy. Path analyses on the data over each of the four test weeks provided support for the proposed model.

Results of the healthy body healthy spirit trial.

Healthy Body Healthy Spirit was a multicomponent intervention to increase fruit and vegetable (F & V) consumption and physical activity (PA) delivered through Black churches. Sixteen churches were randomly assigned to 3 intervention conditions. At baseline, 1,056 individuals were recruited across the 16 churches, of which 906 (86%) were assessed at 1-year follow-up. Group 1 received standard educational materials, Group 2 received culturally targeted self-help nutrition and PA materials, and Group 3 received the same intervention as did Group 2 as well as 4 telephone counseling calls based on motivational interviewing (MI) delivered over the course of 1 year. At 1-year follow-up, Groups 2 and 3 showed significant changes in both F & V intake and PA. Changes were somewhat larger for F & V. For F & V, but not PA, there was a clear additive effect for the MI intervention.
