Adolescents' Self-Efficacy to Overcome Barriers to Physical Activity Scale

Abstract

This paper describes a revised measure of self-efficacy to overcome barriers to moderate and vigorous physical activity in a sample of 484 high school students in Toronto, Ontario. The students had a mean age of 15.3 years. Principal axis factoring with oblique rotation yielded five factors: self-efficacy to overcome internal, harassment, physical environment, social environment, and responsibilities barriers. Two problematic items were removed, which resulted in a 22-item measure. Subsequent analyses were conducted on responses to this shortened measure. Confirmatory factor analysis supported the five-factor model and demonstrated age- and sex-invariance. The subscales had good internal consistency reliability. Structural regressions demonstrated a strong relationship between the resulting factors and a physical activity measure (energy expenditure), showing predictive validity.

High School Sport Participation: Does It Have an Impact on the Physical Activity Self-efficacy of Adolescent Males?

“…The fact that there was a positive relationship between the two variables suggested that one's self-efficacy for activity was related to his ability to participate in physical activity. This finding was consistent with the results of previous research, which stated that self-efficacy was significantly related to physical activity behaviour (Von Ah, Ngamvitroj, Park, & Kang, 2004), specifically in high school aged participants (Allison, Dwyer, & Makin, 1999: Dwyer et al, 2012. The regression showed that SEPAQ score can predict some variability in PAQ-A scores, however high school sport participation did not significantly predict active behaviour or self-efficacy in this sample.…”

“…Specifically, a recent review on physical activity correlates in adolescents found that self-efficacy was significantly and positively related to physical activity in 28 studies (Van Der Horst, Paw, Twisk, & Van Mechelen, 2007). Even more recently, Dwyer et al (2012) found evidence in a sample of Canadian high school students to support the findings of this review.…”

Family and individual predictors and mediators of adolescent physical activity

“…Self-efficacy is believed to be one of the key individual factors determining the initiation and change of healthy behaviours in a person, including physical activity (Dishman et al, 2004;Dwyer et al, 2012;Wienert, Kuhlmann, & Lippke, 2015;Zhou, Sun, Knoll, Hamilton, & Schwarzer, 2015). Due to the fact that one of the most significant sources of self-efficacy is a person's own early, positive experiences of activity (mastery experiences), observing the success of significant persons (vicarious experiences/modelling) and feedback obtained from them (verbal persuasion), it is the influence of parents that plays a key role in shaping self-efficacy in children.…”

Enhancing the Content Validity of Self-Reported Physical Activity Self-Efficacy in Adolescents: A Qualitative Study

“…4 Personreported outcome measures (PROMs) were used to assess different aspects of self-efficacy specific for PA in adolescents such as task-or self-regulatory (mainly overcoming barriers) self-effiacy. [9][10][11][12][13][14][15] Among the existing self-regulatory PA self-efficacy PROMs, the recently developed Self-Efficacy to Overcome Barriers to Physical Activity Scale (SOBPAS) by Dwyer et al 10 and the Perceived Physical Activity Self-Efficacy Scale (P-PASES) by Wu et al 14 have demonstrated adequate psychometric properties in adolescents. 10,14 Both instruments were developed to measure adolescents' confidence in ability to overcome different barriers to participate in PA (eg, bad weather, not having enough skills, and not having social support).…”
