► We explored psychometric characteristics of the QABF to the Spanish population. ► Data from 300 participants with intellectual disabilities and 328 behavioral problems were obtained. ► Exploratory factor analysis identified the five hypothesized subscales of the QABF. ► Test-retest reliability from 40 problem behaviors assessed indicate that the QABF has good stability over time.
