TLDR
A set of criteria based upon biostatistical considerations for determining the interrater reliability of specific adaptive behavior items in a given setting was presented and guidelines for differentiating type of adaptive behavior that are statistically reliable from those that are reliable in a clinical or practical sense were delineated.Abstract:
A set of criteria based upon biostatistical considerations for determining the interrater reliability of specific adaptive behavior items in a given setting was presented. The advantages and limitations of extant statistical assessment procedures were discussed. Also, a set of guidelines for differentiating type of adaptive behavior that are statistically reliable from those that are reliable in a clinical or practical sense was delineated. Data sets were presented throughout in order to illustrate the advantages of recommended statistical procedures over other available ones.read more

Is the CVI an acceptable indicator of content validity? Appraisal and recommendations
TL;DR: In this article, the authors compared the CVI to alternative content validity indexes and concluded that the widely-used CVI has advantages with regard to ease of computation, understandability, focus on agreement of relevance rather than agreement per se, and focus on consensus rather than consistency, and provision of both item and scale information.
Focus on research methods. is the cvi an acceptable indicator of content validity? appraisal and recommendations
TL;DR: This work translates item-level CVIs (I-CVIs) into values of a modified kappa statistic and suggests that items with an I-CVI of .78 or higher for three or more experts could be considered evidence of good content validity.

Visual fixation patterns during viewing of naturalistic social situations as predictors of social competence in individuals with autism.
TL;DR: A novel method of quantifying atypical strategies of social monitoring in a setting that simulates the demands of daily experience is reported, finding that fixation times on mouths and objects but not on eyes are strong predictors of degree of social competence.

TL;DR: Clinical guidelines for the diagnosis of autism in the draft version of ICD-10 were operationalized in terms of abnormalities on specific ADOS items, and an algorithm based on these items was shown to have high reliability and discriminant validity.
