A - 166 Predictors of Intention to Participate in Programmed Exercise for Postconcussion Recovery.

Abstract

Programmed exercise has been proposed for postconcussion recovery, but willingness to engage in such programs has not been explored. This study investigated sociocognitive factors from the Theory of Planned Behavior (TPB) and their relationship to exercise intention for postconcussion recovery (intention). Four hundred and fifty-nine adults completed an online survey (Age = 18-72years, 34% concussion history). All participants received information about mTBI, postconcussion symptoms, and programmed exercise. The measures assessed TPB constructs including intention, and evaluated program design features that could affect engagement (e.g., session frequency). Structured equation modelling found that intention was significantly predicted (p < 0.05) by subjective norms (strongest predictor) and perceived behavioral control (weaker predictor). Attitudes did not significantly predict intention. The model accounted for approximately half of the variance in exercise intention (R2 = 0.506). The addition of moderators (habitual exercise, concussion history) did not have any effect. Key program design features were personalization and supervision. People's intention to undertake programmed exercise for postconcussion recovery is shaped by individual psychological factors, especially subjective norms and perceived behavioral control. This could be considered in the program design (e.g., building program connections with significant others; fostering a sense of control through personalization/session timetabling). Further research is needed to establish the effect of such additions on engagement with programmed exercise for postconcussion recovery.
