The Development of a Physical Activity Barriers Questionnaire for Youth with Visual Impairments

Abstract

We developed a preliminary Physical Activity Barriers Questionnaire for Youth with Visual Impairments (PABQ-VI) using social cognitive theory as the guiding theoretical framework. Twenty-one youth with VI in Ireland participated in our study. Validity (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.
