Validation of the Italian version of the Functioning Assessment Short Test (FAST) for bipolar disorder.

ABSTRACT: Aim. The Functioning Assessment Short Test (FAST) is a useful instrument for the assessment of overall functioning of people with bipolar disorder, showing good psychometric properties. The aim of this study is to validate the Italian version of FAST. Methods. Translation and back-translation of the original FAST Spanish version were performed. Participants with bipolar disorder (n = 132) and healthy controls (n = 132) completed the FAST as a part of an assessment package including the Montgomery-Asberg Depression Rating Scale and the Young Mania Rating Scale. Internal consistency, inter-rater reliability, construct and discriminant validity were assessed. Results. The FAST Italian version showed good internal consistency, inter-rater reliability and discriminant validity. The cut-off discriminating patients from controls was 15, with a sensitivity of 0.79 and a specificity of 0.80. Principal component analysis with oblique rotation showed factor loadings consistent with the a priori structure of the instrument. Conclusions. This study confirmed the psychometric properties of FAST and extended its generalization and validity to the Italian population.

Project description:ObjectivesTo determine the criterion and concurrent validity of the Italian version of the short 10/66 Dementia Diagnostic Schedule and algorithm in a sample of Italian native speakers, older adults.DesignA cross-sectional, validation study.SettingThe study was conducted with older adults living in the community and in nursing homes in the Canton of Ticino, Switzerland, and the Piedmont region in Italy between March and August 2019.ParticipantsA convenience sample of 229 participants (69% females) were recruited. The eligibility criteria were being ≥60 years old and having an informant. The final sample included 74 participants (32%) with a previous clinical diagnosis of dementia and 155 (68%) cognitively healthy older adults.Primary and secondary outcome measuresThe short version of 10/66 Dementia Diagnostic Schedule consists of the Community Screening Instrument for Dementia, the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) 10-word list learning task with delayed recall and the depression scale, Euro-Depression (EURO-D) scale. Disability was measured using the WHO Disability Assessment Schedule (WHO-DAS II).ResultsThe Italian version of the short 10/66 Dementia Diagnostic Schedule showed fair sensitivity (87%), specificity (61%) and agreement with the clinical diagnosis of dementia (kappa=0.40, area under the receiver operating characteristics curve=0.74). Older adults with dementia living in nursing homes had higher disability scores (WHO-DAS II mean=23.14, SE=1.29) than those living in the community (WHO-DAS II mean=7.08, SE=0.66). WHO-DAS II was positively correlated with the short version of the 10/66 dementia diagnosis (β=5.23, 95% CI 2.05 to 8.41).ConclusionsIn settings where lengthy diagnostic procedures are not feasible, the short 10/66 is a practical tool to identify dementia in older adults. Our findings extend evidence on the validity of the 10/66 dementia diagnostic algorithm to high-income countries, where epidemiological evidence on dementia and its impact is outdated.

Project description:INTRODUCTION:Impairments in the ability to understand others and the self in terms of internal mental states (reflective functioning [RF] or mentalizing) are thought to play a key role in the development of borderline personality disorder (BPD). The first aim of this study was to validate the Italian version of the Reflective Functioning Questionnaire (RFQ), a brief self-report measure of RF, by examining its factor structure with Principal Component Analyses (PCA), and correlations with constructs that should be theoretically related to RF. In addition, we investigated whether the RFQ could empirically distinguish between healthy controls and carefully diagnosed BPD patients using Research Operating Curve methods, and was related to severity of borderline pathology as measured with the Shedler-Westen Assessment Procedure (SWAP), an observer-rated measure of BPD pathology. METHODS:An Italian translation of the RFQ was administered to a sample of 154 healthy controls and a clinical sample of 59 BPD patients diagnosed with the Structured Clinical Interview for DSM-IV Axis II disorders. Clinical severity of BPD was assessed with the SWAP. Normal controls completed self-report inventories of constructs related to RF (mindfulness, empathy, Theory of Mind, alexithymia, and autistic traits). RESULTS:PCA confirmed the a priori factor structure in the Italian translation of the RFQ, showing two subscales that measure certainty and uncertainty about mental states, with satisfactory reliability and construct validity. These dimensions also distinguished BPD patients from healthy controls (p < 0.05). ROC analyses showed that the uncertainty subscale discriminated BPD patients from healthy individuals (area under the curve = 78%, cut of 4.5 points, sensitivity = 73%, specificity = 68%). Within the patient group, regression analyses showed uncertainty about mental states to have a significant unique contribution in predicting BPD severity (p < 0.05), explaining 12% of the variance. CONCLUSIONS:Results largely supported the reliability and validity of the Italian version of the RFQ. These findings also provide further evidence for the role of impairments in mentalizing and reinforce the rationale for offering mentalization-based interventions to individuals with this disorder.
