Abstract

PURPOSE:

This study compares the efficacy of a self-help intervention tailored to the individual's stage of motivational readiness for exercise adoption with a standard self-help exercise promotion intervention.

DESIGN:

Interventions were delivered at baseline and 1 month; assessments were collected at baseline and 3 months.

SETTING:

Eleven worksites participating in the Working Healthy Research Trial.

SUBJECTS:

Participants (n = 1559) were a subsample of employees at participating worksites, individually randomized to one of two treatment conditions.

INTERVENTION:

Printed self-help exercise promotion materials either (1) matched to the individual's stage of motivational readiness for exercise adoption (motivationally tailored), or (2) standard materials (standard).

MEASURES:

Measures of stage of motivational readiness for exercise and items from the 7-Day Physical Activity Recall.

RESULTS:

Among intervention completers (n = 903), chi-square analyses showed that, compared to the standard intervention, those receiving the motivationally tailored intervention were significantly more likely to show increases (37% vs. 27%) and less likely to show either no change (52% vs. 58%) or regression (11% vs. 15%) in stage of motivational readiness. Multivariate analyses of variance showed that changes in stage of motivational readiness were significantly associated with changes in self-reported time spent in exercise.

CONCLUSIONS:

This is the first prospective, randomized, controlled trial demonstrating the efficacy of a brief motivationally tailored intervention compared to a standard self-help intervention for exercise adoption. These findings appear to support treatment approaches that tailor interventions to the individual's stage of motivational readiness for exercise adoption.
