Revision of a method quality rating scale for single-case experimental designs and n-of-1 trials: The 15-item Risk of Bias in N-of-1 Trials (RoBiNT) Scale
Recent literature suggests a revival of interest in  single-case methodology  ( e.g. , the r and omised n-of-1 trial is now considered Level 1 evidence for treatment decision purpose s by the Oxford Centre for Evidence -Based Medicine ) . Consequently , the availability of tools to critically appraise single-case reports is of great importance . We report on a major revision of our method quality instrument , the Single-Case Experimental Design Scale . Three changes result ed in a radically revised instrument , now entitled the Risk of Bias in N-of-1 Trials ( RoBiNT ) Scale : ( i ) item content was revised and increased to 15 items , ( ii ) two subscales were developed for internal validity ( IV ; 7 items ) and external validity and interpretation ( EVI ; 8 items ) , and ( iii ) the scoring system was changed from a 2-point to 3-point scale to accommo date currently accepted st and ards . Psychometric evaluation indicated that the RoBiNT Scale showed evidence of construct ( discriminative ) validity . Inter-rater reliability was excellent , for pairs of both experienced and trained novice raters . Intraclass correlation coefficients of summary scores for individual ( experienced ) raters : ICCTotalScore = .90 , ICCIVSubscale = .88 , ICCEVISubscale = .87 ; individual ( novice ) raters : ICCTotalScore = .88 , ICCIVSubscale = .87 , ICCEVISubscale = .93 ; consensus ratings between experienced and novice raters ( ICCTotalScore = .95 , ICCIVSubscale = .93 , ICCEVISubscale = .93 . The RoBiNT Scale thus shows sound psychometric properties and provides a comprehensive yet efficient examination of important features of single-case methodology
