The Florida Obsessive-Compulsive Inventory (FOCI) is a new self-report questionnaire that has separate scales for symptom enumeration (The Checklist) and evaluation of symptom severity (Severity Scale). The present research investigated the FOCI in a sample of 113 patients with obsessive-compulsive disorder (OCD). The results indicated that the FOCI Severity Scale is internally consistent (alpha = .89) and highly correlated with the total score from the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS; Goodman et al., 1989 a). The correlations of the FOCI Severity Scale with measures of depression and global severity of psychopathology were similar to those obtained with the Y-BOCS Total Severity Score. The FOCI Symptom Checklist had adequate reliability (K-R 20 = .83) and moderate correlations (rs < .45) with the FOCI Severity Scale, the Y-BOCS scales, and measures of depression and severity of psychopathology. These findings imply concurrent validity for the FOCI Severity Scale. A strength of the FOCI is that it offers a quick evaluation of both presence and severity of OCD symptoms. An important limitation is that the FOCI does not assess the severity of individual symptoms.

    • "The original FOCI, from which our screen was derived, was designed as a self-report measure (Storch et al., 2007) and is available on many OCD related websites. The FOCI has moderate correlation with Yale Brown Obsessive Compulsive Scale (YBOCS) obsessive, compulsive, and total severity scores (correlations ¼0.71 to 0.87) (Storch et al., 2007). However, to our knowledge, the FOCI has not been validated against the current gold standard, an OCD diagnosis obtained by clinician-administered, structured interview . "

    ABSTRACT: Collecting phenotypic data necessary for genetic analyses of neuropsychiatric disorders is time consuming and costly. Development of web-based phenotype assessments would greatly improve the efficiency and cost-effectiveness of genetic research. However, evaluating the reliability of this approach compared to standard, in-depth clinical interviews is essential. The current study replicates and extends a preliminary report on the utility of a web-based screen for Tourette Syndrome (TS) and common comorbid diagnoses (obsessive compulsive disorder (OCD) and attention deficit/hyperactivity disorder (ADHD)). A subset of individuals who completed a web-based phenotyping assessment for a TS genetic study was invited to participate in semi-structured diagnostic clinical interviews. The data from these interviews were used to determine participants׳ diagnostic status for TS, OCD, and ADHD using best estimate procedures, which then served as the gold standard to compare diagnoses assigned using web-based screen data. The results show high rates of agreement for TS. Kappas for OCD and ADHD diagnoses were also high and together demonstrate the utility of this self-report data in comparison previous diagnoses from clinicians and dimensional assessment methods.

    • "Members of the obsessive–compulsive spectrum disorders subworkgroup of the DSM-5 anxiety, obsessive–compulsive spectrum, posttraumatic, and dissociative disorder work group created a template for OCRDs that was adapted from the Florida obsessive compulsive inventory (FOCI; Storch et al., 2007). The FOCI is a 25-item self-report scale for OCD that has demonstrated strong psychometric properties, including strong correlation with the clinician-rated Yale–Brown obsessive compulsive scale (Y–BOCS; Goodman et al., 1989), which is considered the ''gold standard'' in OCD assessment.

    ABSTRACT: There will be several changes to the diagnosis of obsessive–compulsive and related disorders (OCRDs) in DSM-5. Several disorders, including body dysmorphic disorder (BDD), hoarding disorder (HD), trichotillomania (hair-pulling disorder) (TTM), and excoriation (skin-picking) disorder (SPD), will be included alongside obsessive compulsive disorder (OCD) in a distinct diagnostic category of OCRDs. Also, dimensional assessments of psychopathology will be included to supplement traditional categorical diagnoses. The DSM-5 subworkgroup on obsessive–compulsive spectrum disorders developed a set of brief self-rated scales for BDD, HD, TTM, and SPD that are consistent in content and structure, reflect DSM-5 criteria, and can be used by clinicians to help generate a dimensional severity rating for the disorders. In the present paper, we discuss the scales’ creation and examine their psychometric properties in a large non-clinical sample (n=296). The scales each demonstrated a single factor structure, strong internal consistency (α=.80–.89), convergent validity (rs=.74–.92), and significantly higher total scores in individuals who indicated the presence of the respective disorder’s core symptom on a binary diagnostic screener (Cohen’s d=0.57–2.18). The results provide support for further evaluation of these scales in clinical samples and take an important step toward the integration of standardized dimensional measurement into DSM-5.

    • "Two new self-report questionnaires for OCD are available in addition to the ones mentioned in the 2007 guideline. The Florida Obsessive-Compulsive Inventory includes a symptom checklist (20 items) and a severity scale (5 items) (Storch et al. 2007b). In a study of 113 patients with OCD, this questionnaire exhibited high internal consistency and high correlation with scores on the clinician-rated Yale-Brown Obsessive Compulsive Scale (Y-BOCS). "

    ABSTRACT: Support for the serotonin-1D (5-HT(1D)) hypothesis of obsessive-compulsive disorder (OCD) and related conditions comes from a variety of sources. Some pharmacologic challenges with the 5-HT(1D) agonist sumatriptan, and case reports in which prolonged administration of 5-HT(1D) agonists was associated with a therapeutic effect, suggest that 5-HT(1D) may play a role in obsessive-compulsive symptoms. Genetic studies have also found that polymorphism of the 5-HT(1D) gene may be preferentially transmitted to those patients with OCD. However, taking into account that OCD is a heterogeneous syndrome, the 5-HT(1D) hypothesis requires further investigation in order to disentangle the role of the 5-HT(1D) receptor in this common and often severe disorder.
