Sammanfattning
Background : The Brief Obsessive Compulsive Scale (BOCS), derived from the Yale-Brown
Obsessive-Compulsive Scale (Y-BOCS) and the children ’ s version (CY-BOCS), is a short
self-report tool used to aid in the assessment of obsessive-compulsive symptoms and diagnosis
of obsessive- compulsive disorder (OCD). It is widely used throughout child, adolescent and
adult psychiatry settings in Sweden but has not been validated up to date. Aim : The aim of the
current study was to examine the psychometric properties of the BOCS amongst a psychiatric
outpatient population. Method : The BOCS consists of a 15-item Symptom Checklist including
three items (hoarding, dysmorphophobia and self-harm) related to the DSM-5 category
"Obsessive-compulsive related disorders", accompanied by a single six-item Severity Scale for
obsessions and compulsions combined. It encompasses the revisions made in the Y-BOCS-II
severity scale by including obsessive" compulsive free intervals, extent of avoidance and
excluding the resistance item. 402 adult psychiatric outpatients with OCD, attention-defi cit/
hyperactivity disorder, autism spectrum disorder and other psychiatric disorders completed the
BOCS. Results : Principal component factor analysis produced fi ve subscales titled "Symmetry" ,
"Forbidden thoughts", "Contamination","Magical thoughts" and "Dysmorphic thoughts" . The
OCD group scored higher than the other diagnostic groups in all subscales ( P 0.001).
Sensitivities, specifi cities and internal consistency for both the Symptom Checklist and the
Severity Scale emerged high (Symptom Checklist: sensitivity 85%, specifi cities 62- 70%
Cronbach ’ s á 0.81; Severity Scale: sensitivity 72%, specifi cities 75- 84%, Cronbach ’ s
á 0.94). Conclusions : The BOCS has the ability to discriminate OCD from other non-OCD
related psychiatric disorders. The current study provides strong support for the utility of the
BOCS in the assessment of obsessive-compulsive symptoms in clinical psychiatry.
