The purpose of this cross-sectional study was to use Ajzen's Theory of Planned Behaviour (TPB) as a theoretical framework for understanding the intention to be physically active among a group of obese individuals. Individuals ( = 96) classified as obese (BMI ≥30 kg/m) completed a self-administered questionnaire assessing intention to be physically active and its theoretically related variables. The TPB explained 66% of the variance in physical activity intentions. Significant independent predictors of intention were perceived behavioural control (β = .40) and attitude (β = .36). The consideration of past behaviour (β = .32) explained an additional 7% of the variance. These findings support the idea that, in designing interventions for obese individuals, nurses should focus on developing skills to overcome barriers to physical activity and on developing a positive attitude towards this behaviour.

Cette étude transversale a pour objectif d'utiliser la théorie du comportement axé sur un objectif (TCAO) d'Ajzen comme cadre théorique pour comprendre l'intention d'activité physique chez un groupe d'individus obèses. Des individus (n = 96) identifiés comme obèses (IMC ≥ 30 kg/m2) ont rempli un questionnaire autoadministré évaluant l'intention d'être physiquement actif et ses variables théoriquement afférentes. L'utilisation de la TCAO a expliqué 66% de la variance liée aux intentions d'exercice physique. Le contrôle comportemental perçu (β = 0,40) et l'attitude (β = 0,36) constituaient d'importants prédicteurs de comportement indépendants. La pr ise en compte de comportements antérieurs (β = 0,32) a permis d'expliquer 7% des variances. Ces conclusions ont appuyé l'idée selon laquelle les infirmières doivent, à l'étape de la conception d'interventions pour individus obèses, mettre l'accent sur l'acquisition d'habiletés qui permettront de surmonter les obstacles à l'activité physique, ainsi que sur le renforcement de ce comportement.

    Currently published issues of the CJNR (1969-2015) are being moved to the McGill online archives where they will be hosted in perpetuity. This migration should be completed by Spring 2016. During this transition, all issues of CJNR remain accessible to our readers as before:

    1) Past issues of CJNR from 2003 to December 2015 through ingentaconnect.

    2) Issues from 2002 to 1969 can be accessed through the CJNR digital archive.

    We understand that this is a significant change. Please be confident that all parties are working diligently to make this a seamless transition that will further advance the scope and impact of CJNR.

    Thank you.
