Unique aspects of childhood OCD

The incidence and presentation of symptoms in pediatric-onset OCD may differ somewhat from those of adult-onset OCD. For example, strongly consider a diagnosis of OCD if a child or adolescent displays behavioral changes (eg, develops new fears or rituals) after exposure to the streptococcal virus. OCD falls under the category of Pediatric Autoimmune Neurological Disorders Associated with Streptococcus (PANDAS),8 and rapid symptom-onset may reflect this phenomenon.

Symptoms may cause no distress… Though many pediatric patients report multiple symptoms,9 some will not recognize that their symptoms are bizarre or excessive.10 In fact, a subset of pediatric patients may appear undistressed by their symptoms or report that they enjoy engaging in OCD behaviors.11

… or may be incapacitating. However, other children find OCD symptoms overwhelming and may even enlist the help of others (eg, family members) to complete their rituals. Parents of these children frequently report that their child experiences “meltdowns” when the OCD symptoms are not accommodated. Pediatric patients frequently report feeling “stuck” because OCD symptoms interfere with their ability to complete day-to-day tasks (eg, bathing, homework, eating, chores, etc). If you suspect this level of incapacitation, obtain information from parents regarding the impact of symptoms on both child and family functioning.

How to approach the evaluation

Given that symptoms of OCD overlap significantly with other psychiatric and neurologic disorders (eg, general anxiety, psychosis, and mood, pervasive-developmental, and tic disorders), a thorough assessment is crucial to the differential diagnosis of OCD.

Particularly with children, you need to distinguish possible symptoms of OCD from developmentally appropriate rituals (eg, bedtime routines) and fears.12

Inquire about a family history of OCD or other anxiety disorders, either of which increases the likelihood of a diagnosis of OCD.13

Several methods of assessment have been developed that may facilitate your attempt to identify OCD. These include diagnostic interviews, clinician-administered inventories, self-report measures, and (for pediatric patients) parent-report and teacher-report measures.

Diagnostic interviews effective but time consuming. In general, diagnostic interviews are reliable and valid measures that facilitate diagnostic decisions by using questions developed specifically to assess DSM-IV symptoms.7 Good examples include the Anxiety Disorders Interview Schedule for DSM-IV: Child & Parent Versions (ADIS),14 the Schedule for Affective Disorders and Schizophrenia for School-Age Children—Present & Lifetime version (K-SADS-PL),15 and the Structured Clinical Interview Diagnostic for DSM-IV (SCID).16

Each method is highly structured and clinician administered. Such interview techniques assess for anxiety disorders and also include sections to help uncover other psychiatric disorders (ie, disruptive behavior disorders, psychotic disorders, and mood disorders).

However, these interviews are fairly time-consuming and require training to administer. As a result, they are typically administered by a psychologist or other mental health professional.

Clinician-administered measures are reliable and efficient. These inventories allow trained clinicians to rate a patient’s level of impairment and distress compared with other patients they have seen. The most commonly-used “gold standard” measures are the Yale-Brown Obsessive Compulsive Scale (Y-BOCS)17,18 for adults, and the Children’s Yale-Brown Obsessive Com-pulsive Scale (CY-BOCS)19 for youth. The Y-BOCS and the CY-BOCS are semi-structured inventories of OCD symptom presence and severity over the previous week. Both measures have repeatedly demonstrated good reliability and validity,17-22 and they can be completed in approximately 15 minutes.

Self-report and parent-report questionnaires may be most helpful. You may find self- or parent-report questionnaires most useful in your practice, because they can be completed quickly and without your assistance. The measures are particularly useful as screening devices, and thus can also be used to identify patients who may benefit from referral to a psychologist or psychiatrist for a more comprehensive evaluation. An additional strength of these questionnaires is that they can easily be readministered to assess posttreatment change.

For the assessment of adult OCD, we use the Florida Obsessive Compulsive Inventory (FOCI)23 and Obsessive Compulsive Inventory—Revised (OCI-R).24 The FOCI, which is reprinted in APPENDIX A, is a brief measure that screens for common OCD symptoms and assesses the severity of OCD impairment in patients with OCD. The OCI-R is a theoretically-driven instrument that assesses the extent to which individuals are “distressed or bothered” by common OCD symptoms.

For assessment of pediatric OCD, several self-report and parent-report measures have been developed,25 and many are useful for diagnostic decisions.

First, the Children’s Obsessional Compulsive Inventory (ChOCI)26 assesses for obsessive symptoms and compulsive symptoms, and the degree of impairment experienced as a result of symptoms.
