Gayathri and Tiwari studied the psychometric properties of their Kannada translation of a parental behaviour scale for children with autistic spectrum disorders. We wish to express our concerns regarding some of their methods and findings.
First, the authors examined test-retest reliability in a sample of only three parents. This is far too small a sample to allow credible conclusions about the reliability of an instrument. Whereas it could have been challenging for the authors to estimate, in advance, a necessary sample size to identify an unknown value for the reliability, it would have been desirable to recruit a sample of at least 30 parents so as to reasonably represent the population.
Next, the authors reported that the intra-class correlation coefficient (ICC) value for test-retest reliability was 0.993. This is an incredibly high level of agreement and is credible only if the authors were assessing facts that do not change. However, they were assessing the agreement on 50 different items, rated on a 1–5 point scale, at time points that were 15–30 days apart. In such circumstances, such a high value for the ICC seems impossible.
Finally, the authors asked three speech-language pathologists to indicate their agreement/disagreement with each item of the scale and to provide suggestions/modifications. The authors wrongly described this exercise as inter-rater reliability. Inter-rater reliability is actually the agreement between different raters who each use the instrument to assess the same patients at the same point in time.
