Motivation Assessment Scale

The Motivation Assessment Scale (MAS) is a quick, user-friendly indirect assessment tool that “assesses the functions or motivations of behaviour problems”. In other words, it helps us better understand why someone does what they do.

The MAS consists of 16 questions which describe situations in which the behaviour might occur. All you have to do is circle how often
(from never to always) the behaviour occurs in different situations. When you have answered all 16 questions, you total the scores using a simple scoring sheet.The results on the scoring sheet suggest what the function (or functions) of the behaviour are
– sensory, tangible, attention or escape. The simplest way to use the scoring sheet is to look at the function with the highest score – this is the most likely function of the behaviour.
