Psychometric tools providing quantitative measures of the constructs of adaptive behavior, support needs, and quality of life (QOL) have received considerable attention within the field of intellectual disability (ID). The relationship between the three constructs was investigated by examining scores on the Adaptive Behavior Scale (ABS), Supports Intensity Scale (SIS), and Personal Outcomes Scale (POS; a QOL scale). Data from 146 Portuguese adults with ID revealed that: (a) the ABS domains showed a moderate negative relationship with the SIS subscales; (b) the absolute value of correlations between SIS/ABS domains were greater than either the ABS/POS or SIS/POS correlations; and (c) people with relatively stronger adaptive skills and less intense support needs experience a higher QOL. Additionally, adaptive behavior scores were a stronger predictor of personal outcomes than the support needs scores. Personal outcomes associated with QOL were similar when assessed by the POS through self-report and report-of-others measures. Implications for future research and practice are discussed.The final publication is available at Springer via http://dx.doi.org/10.1007/s10882-016-9514-0
