Dimensional system of classification: Graded and transitional approach?

[vashappenin]

Hey all,
So in the study design under mental health it says dimensional (graded and transitional) approaches of classification
But I'm still confused about the difference between graded and transitional approaches.. And do we need to know the strengths and limitations of the dimensional approach as a whole or between graded and transitional too? Can someone please explain?

Thanks in advance

Graded involves measuring ones characteristics on a continuum while transitional involves seeing a patients response to treatment by showing the difference (before and after) on a dimensional graph.
AS FAR AS I know, we don't need to know the limitations or strengths for these (I'm going to double check to be sure though) Mainly focus on the limitations and strengths of the whole approach.

Ok thanks for that! Graded is easy to understand, it's just transitional that I'm confused with..

My understanding is that in dimensional approaches, grading is describing the degree to which a person shows a particular behaviour or personality characteristic (e.g. where on the continuum they are likely to be, how severe a behaviour is etc). Grading allows evaluation over time (transitional).

Transitional is the stability/variability of the behaviour over time - in the dimensional approach it is recognised that behaviours are dynamic, context-depending and changing and this is monitored.

Monitoring the transitional aspects allows evaluation of progress and response to treatment.

So basically, change over time.
