30ppl w OCD interviewed

Developed a list of 65 true and false statements

Given to 2 groups of ppt

Yale-brown obsessive compulsive scale (Y-BOCS)

Semi-structured interview- approx 30 mins

10 items= total- for the last week

5- obsessions

5- compulsions

0-4 scale

Y-BOCS score

8 to 15= mild

16 to 23= moderate

24 to 31= severe

32 to 40= extreme

Interviews checklist for Y-BOCS

>50 types of obsessions + compulsions divided into 15 categories

Eval of Y-BOCS

S- strong inter-rater relatability- tested 40 ppl w OCD using this. Each assessed by 4 interviewers. Agreement- shows Y-BOCS is a reliable measure of OCD symptom severity

W- only considers symptom severity in the last week- ppl may experience their symptom’s, throughout in diff ways throughout the week.

Example of weakness of Y-BOCS

Symptoms might be worse on days where the person isn’t at work- important cuz w/o qualitative data putting scores into context is difficult to get an accurate impression of the impact that the symptoms r having on the overall functioning

Diff between Y-BOCS + MOCI

MOCI- self- report

Y-BOCS- completed by clinician

Scores on both r weakly correlated- due to the way data is collected
