The aims of this study were to revisit the reliability and normative values of this test, and establish normative equations accounting for several factors.
The results of a study in China on the validity, reliability and normative scores of a Chinese translation of the Strengths and Difficulties Questionnaire (SDQ) were recently published in your online journal on 29 April 2008 by Du et al [ 1].
To evaluate psychometric properties (convergent and divergent validity; alternate forms reliability) and provide normative data for the Alternating Names Test (ANT), a new bedside test of set-switching, a component of executive function (EF).
To ensure that a test is adequately interpreted, there is a need for multiple sources of validity evidence (American Education Research Association et al. 2014), in addition to reliability, standardization, and normative comparison procedures.
20 Its reliability, validity, and normative data are well documented.
To ensure reliability of assessing normative need, 280 subjects of the 2,788 were re-examined.
The Hammill et al. (1992) scoring system awards the rating of the tool's reliability, validity and normative data as either 'good' A, 'acceptable' B or 'unacceptable'—F.
The Hammill et al. scoring system awards the rating of a tool's reliability, validity and normative data as either 'good' A, 'acceptable' B or 'unacceptable'—F.
All the assessment tools were 'not recommended' due to the existence of 'unacceptable' reliability, validity or normative data based on the Hammil scoring system.
To obtain a final score, normative, reliability and validity ratings were combined to provide an overall rating of the scales as being either 'highly recommended' (two As), 'recommended' (As and/or Bs) or 'not recommended' (any Fs).
