Florida Obsessive-Compulsive Inventory: development, reliability, and validity.
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: 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.Journal of Obsessive-Compulsive and Related Disorders 04/2013; 2(2):114–118.

ABSTRACT: This report describes the development and psychometric properties of the Children’s Florida Obsessive Compulsive Inventory (C-FOCI). Designed specifically as a brief measure for assessing obsessive–compulsive symptoms, the C-FOCI was created for use in both clinical and community settings. Study 1 included 82 children and adolescents diagnosed with primary Obsessive–Compulsive Disorder, and their parents. The Children’s Yale-Brown Obsessive–Compulsive Scale (CY-BOCS) was administered to assess symptom severity. Thereafter, parents completed the Child Obsessive–Compulsive Impact Scale—Parent Version and Child Behavior Checklist, and youth completed the C-FOCI, Child Obsessive–Compulsive Impact Scale—Child Version, Multidimensional Anxiety Scale for Children, and Children’s Depression Inventory—Short Form. A subgroup of 21 individuals was retested with the C-FOCI after completing 14 sessions of intensive cognitive-behavioral therapy. Construct validity of the C-FOCI was supported vis-à-vis evidence of treatment sensitivity, and moderate relations with clinician-rated symptom severity, the CY-BOCS Symptom Checklist, child- and parent-rated functional impairment, child-rated anxiety, and parent-rated internalizing symptoms. Discriminant validity was evidenced by weak relationships with parent-reports of externalizing symptoms. For Study 2, 191 non-clinical adolescents completed the C-FOCI to assess the feasibility of internet administration. Overall, internal consistency was acceptable for the C-FOCI Symptom Checklist and Severity Scale, and respondents were able to complete the measure with little difficulty. Taken together, the findings of Studies 1 and 2 provide initial support for the reliability and validity of the C-FOCI for the assessment of pediatric obsessive–compulsive symptoms.Child Psychiatry and Human Development 09/2009; 40(3):467-483.

ABSTRACT: The assessment of varied psychiatric disorders, including obsessive–compulsive disorder (OCD), is shifting towards the use of evidence-based assessments (EBAs). This shift has fostered the development, validation and adaptation of several measures to rate obsessive–compulsive symptoms and other related problematic areas such as functional impairment or family attitudes among others. The aim of this paper is to present a systematic review of psychometric studies on pediatric OCD-specific measures to classify these according to assessment evidence-based criteria. Selection criteria that determined which studies were included in the review were: (1) analyzing an OCD measure and (2) including participants’ age being 18 years or younger. The literature search procedure was conducted in Medline, PsycINFO, PsycARTICLES, ERIC, Cochrane Library, and Scholar Google databases and enabled us to locate 42 studies which analyzed psychometric properties of 14 OCD measures studied in children and adolescents. Instruments were grouped into the following assessment areas: symptom presence and severity, functional impairment, family functioning and cognitive dimensions of OCD. Psychometric data regarding internal structure, internal consistency, reliability, validity and diagnostic precision were also reported. Further, measures were classified as well-established, approaching well-established and promising assessments in terms of reliability and validity. We concluded that the assessment of OCD in pediatric populations is a growing field that in a short-medium term could provide a wide variety of EBAs for the evaluation obsessive–compulsive symptoms and other OCD-related dimensions. The paper concludes by highlighting directions for future research.Journal of Child and Family Studies 11/2014; 23(8). DOI:10.1007/s10826-013-9801-7 · 1.42 Impact Factor
