Development and psychometric evaluation of the exercise benefits/barriers scale

Abstract

Initial psychometric evaluation of an instrument to measure perceived benefits of exercise and perceived barriers to exercise was based on the responses of 650 adults and included item analysis, factor analysis, and reliability measures. Factor analysis yielded nine factors, five benefits and four barriers, which explained 64.9% of the variance in the 43-item instrument. Second order factor analysis resulted in a two-factor solution, one a benefits factor and the other a barriers factor. The standardized Cronbach's alpha reliability coefficients were: .952 for the total scale, .953 for the benefits scale, and .886 for the barriers scale. Use of the instrument in research involving perceptions of the benefits of exercise and the barriers to exercise appears warranted.

Outcomes of a program to enhance exercise self‐efficacy and improve fitness in black and hispanic college‐age women

“…An analysis of the pre-program scores of the higher attendance and lower attendance groups revealed no statistically significant differences on any of the preprogram measures, except for the Modified Sit and Reach test, where the lower attendance women scored higher (were slightly more flexible) than higher attendance women [t (42)=−2.49, p =.03]. Mean scores for the pre-program assessments of exercise self-efficacy and exercise benefits and barriers were consistent with those published elsewhere (Sechrist, Walker, & Pender, 1987;Wallace & Buckworth, 2003).…”

Can Doping be a Good Thing? Using Psychoactive Drugs to Facilitate Physical Activity Behaviour

“…Compared to watching television (zero effort), even moderate-intensity physical activities like walking require considerable effort. These considerations are supported by early surveys showing that ''physical exertion/effort'' is one of the main barriers to regular physical activity [9,10]. More recently, laboratory and prospective studies of affect during and after exercise [11,12] have provided further evidence that sensations experienced during exercise are important correlates of physical activity behaviour in adults [5].…”

“…This is double the time required to meet the vigorous physical activity guidelines (75 min per week). Given that time is perceived to be one of the main barriers to regular physical activity [9,10], vigorous exercise has a clear advantage over moderate-intensity exercise as a way to meet the current physical activity guidelines. There is also growing physiological and epidemiological evidence that vigorous exercise may be essential to maximise the benefits of physical activity [15][16][17][18].…”
