Transtheoretical model may help to identify OSA patients' level of intention to exercise
Date:12/15/2007

WESTCHESTER, Ill. Research has shown a strong relationship between weight and obstructive sleep apnea (OSA). Your neck gets thicker as you gain weight. This increases the level of fat in the back of the throat, making your airway more likely to be blocked. Because exercise reduces body weight, it has been suggested as a potential intervention for mild to moderate OSA. In an effort to answer the question as to how ready OSA patients are to engage in exercise, a study published in the December 15 issue of the Journal of Clinical Sleep Medicine (JCSM) features the Stages of Change, a construct of the Transtheoretical Model (TTM) of behavior change.

The study focused on 255 patients attending a public hospital based sleep disorders center in Queensland who were being tested for probable OSA. The participants filled out questionnaires that assessed their intention to exercise.

The Stages of Change in the Transtheoretical Model are as follows:

  • Stage: Pre-contemplation
    Intent / Action: No intention to exercise in next six months, no action

  • Stage: Contemplation
    Intent / Action: Serious intent to exercise in next six months, no action

  • Stage: Preparation
    Intent / Action: Serious intent to exercise in next 30 days, some action

  • Stage: Action
    Intent / Action: Exercise regularly, but for less than six months

  • Stage: Maintenance
    Intent / Action: Exercise regularly, for more than six months

    The following measures were used in this study to assess demographic variables and level of habitual self-reported exercise, and to assess the TTM:

    • The Decisional Balance Inventory (consists of 10 items assessing the Pros of exercise and 10 items assessing the Cons of exercise).
    • Self-Efficacy Scale (represents situations that may be considered as potential barriers to exercising).
    • Stages of Change for Regular Exercise (measure assessed exercise-related i
