Abstract :We developed a preliminary Physical Activity Barriers Questionnaire for Youth with Visual Impairments insert ignore into journalissuearticles values(PABQ-VI); using social cognitive theory as the guiding theoretical framework. Twenty-one youth with VI in Ireland participated in our study. Validity insert ignore into journalissuearticles values( content test, internal structure , and relations to other variables ); and reliability evidence of the PABQ-VI scores were examined. Content test validity evidence was assessed using a panel of experts. Item-total correlations were used to assess internal structure validity evidence , and resulted in the removal of nine items. Bivariate correlations were conducted to establish relations to other variables validity evidence. Results revealed that scores obtained on the PABQ-VI were negatively correlated with physical activity levels, but not significantly correlated with self-efficacy for overcoming barriers. Omega and spilt-half reliability estimates were used to establish reliability evidence. Results of these calcuations revealed high reliability estimates. The development of the PABQ-VI will assist researchers to quickly identify PA barriers that limit youth with VI, and to help inform the design of future PA interventions.
