This study examined relationships between general adaptive behavior and the degree of community independence displayed by 272 adults with intellectual disabilities. Specifically, the Adaptive Behavior Assessment System—Second Edition (ABAS-II; Harrison & Oakland, 2003) was completed for each participant and compared with actual levels of work and residential independence. The participants' adaptive behavior accounted for 40%–43% of the variance in their work and residence independence. The results from this field-based study indicated that participants who displayed higher levels of adaptive behavior generally worked and lived more independently. Participants with the lowest general adaptive behavior required the highest degree of community supports. Implications of these findings are discussed.
