Psychometric properties of the portuguese version of the adaptive behavior scale.

Santos et al. (2014) translated the Adaptive Behavior Scale into Portuguese. They then tested if the new version gives steady scores and truly measures adaptive skills.

The team worked with people with intellectual disability and typical peers. They followed the cross-cultural steps laid out in Rasing et al. (1992): translate, back-translate, pilot, then check stats.

The Portuguese scale showed good reliability and validity. In plain words, it gives consistent results and really tracks how clients dress, cook, work, and socialize.

This study copies the method Badia et al. (2012) used to validate the Spanish Leisure Assessment Inventory. Both teams adapted a Western tool into a new language and ran the same psychometric checks.

Schaaf et al. (2015) asked whether we even need adaptive behavior scales for funding. They found support-needs tools alone predict dollars, while adding adaptive scores adds no value. Sofia’s positive results do not clash with C et al.; they simply show the scale works, not that it must drive funding.

Davis et al. (2009) warned that the Rosenberg Self-Esteem Scale is weak for adults with ID. Sofia’s work offers a positive counterpoint: the Portuguese Adaptive Behavior Scale is strong, so you can trust its scores when planning skill goals.

If you serve Portuguese-speaking clients with ID, you now have a proven tool. Use it to spot skill gaps, write baseline goals, and show progress to funders. Swap it in next session instead of guessing or using an English form.
