In the article Stanish, H., Curtin, C., Must, A., Phillips, S., Maslin, M., and Bandini, L. (2015). Enjoyment, barriers, and beliefs about physical activity in adolescents with and without autism spectrum disorder. Adapted Physical Activity Quarterly, 32(4), 302-317. doi:10.1123/APAQ.2015-0038, the authors omitted acknowledgment that the study was an extension of a larger (parent) study that compared physical activity levels and correlates among adolescents with intellectual disabilities (ID) and typically developing (TD) adolescents. Some of the methods for the study published in this journal are identical to those in the parent study, and the same comparison group of TD adolescents was used for both disability groups (ID and autism spectrum disorder). The online version of the article has been corrected.
