no maladaptive daydreaming is not part of dissociative disorders anymore and has not been since 2013.

in short dissociative disorders include a criteria that reality remains intact where as maladaptive daydreaming condition is considered a psychotic problem where a persons sense of reality does not stay intact. statistically in my location it is seen more in psychotic disorders like schizophrenia.

testing wise a person has to score high on the psychotic range (hallucinations, delusions, losing touch with whats real and what isnt, like they cant tell the difference between their dream worlds and the real worlds situations.)

if you would like to know more about this condition many colleges have psych courses that include this condition as one of the lighter mental problems many have a problem with, you can also find accurate information through library reference departments in psychology section. your treatment provider can also tell you more in detail what maladaptive daydreaming condition is.

unfortunately you wont find in any diagnostic manuals as its in te study the condition phase where people are doing studies to get more information about it.

if you have this problem you may consider asknig your treatment providers if they know of any studies being done on this in your area. I found this to be very helpful to me..

I participated in one study and it was found to be part of my insomnia not my dissociative problems nor my PTSD or OCD. in other words due to lack of getting enough sleep my brain kept slipping into the daydreaming brain waves at the wrong times causing problems with my life. medication for my insomnia stopped the maladaptive daydreaming.
