ABSTRACT 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.

    ABSTRACT: The identification of the gene mutation causing Huntington disease has raised hopes for new treatments to ease symptoms and slow functional decline. As such, there has been a push towards designing efficient pharmacological trials (i.e., drug trials), especially with regard to selecting outcomes measures that are both brief and sensitive to changes across the course of the disease, from subtle prodromal changes, to more severe end-stage changes.

    ABSTRACT: The improvement in interater and test-retest reliability could be considered as one of the better conquests for the last-quarter-of-XXth-century Psychiatry. However, this homogeneity and operativizing of diagnostic criteria has added some disadvantages to diagnostic procedure: high ratios of comorbidity and loss of categorial validity could be considered as undesirable consequences of this event. The use of operative diagnostic systems but not the go-deeply-into psychopathological analysis has removed an important and rich information. This loss of information could compromise the study of ethiopatogenia; correlations between symptoms and neurobiological alterations; and prognosis and therapeutic decisions. We analyze the consequences of this event in the validity of diagnosis, from "major depression" (that may be considered as a less valid category than classical melancholia) to anxiety disorders, dysthymia and somatoform disorders (lossing stability and validity in relation to "neurotic general syndrome" or "neuroticism" as an internalizing condition), and also personality disorders (characterized by longitudinal diagnostic unstability and differents ratios of prevalence, excluding antisocial personality disorder).

    ABSTRACT: 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-deficit/hyperactivity disorder, autism spectrum disorder and other psychiatric disorders completed the BOCS. Results: Principal component factor analysis produced five 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, specificities and internal consistency for both the Symptom Checklist and the Severity Scale emerged high (Symptom Checklist: sensitivity = 85%, specificities = 62-70% Cronbach's α = 0.81; Severity Scale: sensitivity = 72%, specificities = 75-84%, Cronbach's α = 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.
