Abstract

Background: The multi-process action control model (M-PAC) is an integrative model specifically designed to evaluate intention-behaviour gaps (Rhodes, 2017). To date, however, the processes through which intentions are translated into action have largely been underexplored among adolescents. Purpose: The primary purpose of the study was to investigate the distribution of intention-behaviour profiles during late adolescence; and to apply the M-PAC framework to better understand predictors of these profiles. Methods: Our sample included 1176 grade 11 students (Mage=15.85 + 0.38, 45.6% male) that completed an online questionnaire as part of the baseline cohort in the ADAPT study. The questionnaire assessed the reflective, regulatory, and reflexive processes outlined within M-PAC, and a self-reported measure of moderate-to-vigorous PA. Results: Following the use of a novel tertiary split, six intention-behaviour profiles were observed: successful non-intenders (7.1%; n=83), unsuccessful non-intenders (2.8%; n=33), inactive quasi-intenders (20.6%; n=242), active quasi-intenders (19.2%; n=226), unsuccessful intenders (12.5%; n=147) and successful intenders (37.8%; n=445). Descriptive statistics revealed successful intenders reported the highest scores on all M-PAC predictors, followed by unsuccessful intenders. A graded response pattern continued for quasi-intenders and non-intenders, with successful non-intenders scoring the lowest across all M-PAC variables. Conclusions: The current study offers new insight into the intention-behaviour gap by differentiating adolescents with more conviction in their intentions from those that report intention ambivalence to create six intention-behaviour profiles. Findings demonstrate strong support for the core tenets of M-PAC in predicting physical activity intention-behaviour profiles during late adolescence. Funding: The ADAPT study is funded by an Insight Grant from the Social Sciences and Humanities Research Council of Canada.
