Cross-cultural adaptation into Italian and validation of the Frenchay dysarthria assessment - 2

Abstract: A comprehensive evaluation of dysarthria is required to make an accurate differential diagnosis with other communication disorders and plan effective rehabilitation programs. The Frenchay Dysarthria Assessment-2 (FDA-2) is a valid, reliable and widely used protocol for the assessment of dysarthria. An Italian version of the FDA-2 is currently lacking.To perform a cross-cultural adaptation of the FDA-2 in Italian and to validate the Italian version of the FDA-2.Validation study.Inpatient rehabilitation center.69 patients with dysarthria and 112 healthy controls.The FDA-2 was translated and cross-culturally adapted to Italian. The validation study was carried out in 4 steps: (1) 42 audio-recorded samples of FDA-2 items from 11 patients with dysarthria were independently assessed by 7 speech and language pathologists for interrater reliability and re-assessed after 6 weeks for intrarater reliability; (2) 11 patients were simultaneously assessed by 3 speech and language therapists for interrater reliability of the whole Italian version of the FDA-2 and re-assessed within 24 hours for test-retest reliability; (3) the Italian version of the FDA-2 was administered to 112 healthy volunteers to gain normative data; (4) 49 patients with different types of dysarthria were assessed using the Italian version of the FDA-2, the Therapy Outcome Measure impairment scale and the Robertson Profile for the validity analysis.Interrater and intrarater reliability ranged from good to excellent (ICC >0.75) except for 3 audio-recorded items. The overall protocol demonstrated excellent (ICC >0.9) inter-rater and test-retest reliability for all the sections and the total score. Normative data were gained for 6 age groups. For the validity analysis, a statistically significant difference was found between dysarthric patients and healthy subjects for all sections and the total score. The FDA-2 significantly correlated to the therapy outcome measure (r=0.75) and the Robertson Profile (r=0.81).The Italian version of the FDA-2 yield satisfactory reliability and validity, comparable to the psychometric properties of the original version.Speech and language pathologists can rely on a valid and reliable tool in Italian for the assessment of dysarthria in both clinical and research practice.

Discussion on Related Problems for Structural Reliability Design

Abstract: In this paper, the basic feature, implication, criterion of the reliability are to be discussed, including the reliability index, stochastic information, computing of the reliability, probability distribution of failure probability, etc. It is aimed to understand the reliability design/analysis method more extensively and comprehensively.

Method of Fuzzy Modeling in Reliability Prediction Algorithm

Abstract: To introduce a kind of method of fuzzy modeling based on the accuracy of data sources and accessibility of the interface which can predict the future system reliability. Data sources are from Reliability management system, distribution network planning detail and projects of overhaul, capital construction, technical transformation, business expansion. There is little reports of the reliability evaluation algorithm by now. This paper is based on the correlation analysis method of load forecasting to forecast the reliability index.
