Reliable change score software utility

Thanks to Paul Barrett for his recent FYI post about useful software utilities available from Prof. Grant Devilly (Swinburne University [Australia] Centre For Neuropsychology). Avaiable for FREE are the following utilities.
A link to the output from the Reliable Change Generator is provided above. It looks promising. Below is an excerpt from the web page:
  • The Reliable Change Generator was developed to help clinicians, researchers and students to assess whether any change apparent in a client (or anything/one for that matter) isn't just an artefact of measurement. This computer programme was developed to reduce the time it takes to assess reliable change and facilitate the increased use of this statistic in practice and research.
  • You can save files, open saved files and even generate a printed one page summary report to keep in your records.
  • This was developed following my experiences in teaching university psychology and medical students (many of whom hate statistics with a vengeance) and reading research papers where the authors have made some rather large leaps of faith in whether people "improved" or "worsened" over time. If I can give one piece of advice before you embark on measuring reliable change it is this: As with this programme, statistics are tools – not the end product.
