TL;DR: This study demonstrates the psychometric properties of the IcaBI in an Italian stroke population, and shows that the scale can be considered a valid and reliable assessment tool for measuring functional disability in Italian acute ischemic stroke survivors.
Abstract: The objective of this study was to assess and validate the psychometric properties of the Italian culturally adapted Barthel Index (IcaBI) in a cohort of people with ischemic stroke. The validation process was conducted in an Italian cohort of 99 stroke inpatients to whom the IcaBI was administered in order to test its structural validity, and inter-and intrarater reliability. The internal consistency (Cronbach's alpha) was 0.901. Factor analysis revealed a two-factor structure. The interclass correlation coefficient 3,1 (ICC) for intra-rater reliability was estimated at 0.987 (95% CI: 0.975-0.993), while the ICC for inter-rater reliability was 0.909 (95% CI: 0.852-0.948). This study demonstrates the psychometric properties of the IcaBI in an Italian stroke population, and therefore shows that the scale can be considered a valid and reliable assessment tool for measuring functional disability in Italian acute ischemic stroke survivors.

TL;DR: The development of a codebook as a supplement to the assessment tool Observation Scheme-12 enables an objective rating of audiotaped clinical communication with acceptable reliability.
Abstract: The aim of the study was to confirm the validity and reliability of the Observation Scheme-12, a measurement tool for rating clinical communication skills. The study is a sub-study of an intervention study using audio recordings to assess the outcome of communication skills training. This paper describes the methods used to validate the assessment tool Observation Scheme-12 by operationalizing the crude 5-point scale into specific elements described in a codebook. Reliability was tested by calculating the intraclass correlation coefficients for interrater and intrarater reliability. The validation of the Observation Scheme-12 produced a rating tool with 12 items. Each item has 0 to 5 described micro-skills. For each item, the codebook described the criteria for delivering a rating from 0 to 4 depending on how successful the different micro-skills (or number of used jargon words) was accomplished. Testing reliability for the overall score intraclass correlation coefficients was 0.74 for interrater reliability and 0.86 for intrarater reliability. An intraclass correlation coefficient greater than 0.5 was observed for 10 of 12 items. The development of a codebook as a supplement to the assessment tool Observation Scheme-12 enables an objective rating of audiotaped clinical communication with acceptable reliability. The Observation Scheme-12 can be used to assess communication skills based on the Calgary-Cambridge Guide.

TL;DR: This pattern analysis system is easy to use even for inexperienced personnel, and is reliable with high accuracy and specificity, and intrarater and interrater statistics also support its reliability and reproducibility.

TL;DR: The Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) is a reliable outcome measure for cutaneous lupus erythematOSus (CLE) in adults used in clinical trials, but it has not been validated in children, limiting clinical trials for paediatric CLE.
Abstract: Background The Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) is a reliable outcome measure for cutaneous lupus erythematosus (CLE) in adults used in clinical trials. However, it has not been validated in children, limiting clinical trials for paediatric CLE. Objectives This study aimed to validate the CLASI in paediatrics. Methods Eleven paediatric patients with CLE, six dermatologists and six rheumatologists participated. The physicians were trained to use the CLASI and Physician's Global Assessment (PGA), and individually rated all patients using both tools. Each physician reassessed two randomly selected patients. Within each physician group, the intraclass correlation coefficient (ICC) was calculated to assess the reliability of each measure. Results CLASI activity scores demonstrated excellent inter- and intrarater reliability (ICC > 0·90), while the PGA activity scores had good inter-rater reliability (ICC 0·73-0·77) among both specialties. PGA activity scores showed excellent (ICC 0·89) and good intrarater reliability (ICC 0·76) for dermatologists and rheumatologists, respectively. Limitations of this study include the small sample size of patients and potential recall bias during the physician rerating session. Conclusions CLASI activity measurement showed excellent inter- and intrarater reliability in paediatric CLE and superiority over the PGA. These results demonstrate that the CLASI is a reliable and valid outcome instrument for paediatric CLE.
