Because the Global Assessment of Functioning [GAF] measures three independent factors: 1] function, 2] severity of signs and symptoms, or 3] dangerousness, one needs to consider which is more problematic. GAF, placed on Axis V, is determined by selecting the lowest of the three levels one finds on examination. For example, a person who is capable of holding a job, whose psychopathology is limited to mild insomnia, mild anorexia, and some anergy, and so forth and who is very intent on killing herself would be about 05 even though the other levels are above 50.
Do not include physical or environmental limitations in selecting a functional level. At times, one may want to specify timing of the score, such as “35 [current],” “25 [on admission],” “55 [at discharge],” "15 [lowest level during past year]," or "75 [highest level during past year]."
Note that for each category there is a range of ten. While usually a number that ends in “5”or “0” will suffice, this range does allow greater specificity when that would be useful.
