When digital versions of self-report symptom scales are compared to pen and paper versions , most scales show high interformat reliability .
This supports the reliability of results obtained in psychotherapy research on the Internet and the comparability of the results to traditional psychotherapy research .
BACKGROUND Research on Internet-based interventions typically use digital versions of pen and paper self-report symptom scales .
However , adaptation into the digital format could affect the psychometric properties of established self-report scales .
Several studies have investigated differences between digital and pen and paper versions of instruments , but no systematic review of the results has yet been done .
OBJECTIVE This review aims to assess the interformat reliability of  self-report symptom  scales used in digital or online psychotherapy research .
Test-retest reliability of alcohol measures: is there a difference between internet-based assessment and traditional methods?
This study compared Web-based assessment techniques with traditional paper-based methods of commonly used measures of alcohol use . Test-retest reliabilities were obtained , and tests of validity were conducted . A total of 255 participants were r and omly assigned to 1 of 3 conditions : paper-based ( P&P ) , Web-based ( Web ) , or Web-based with interruption ( Web-I ) . Follow-up assessment s 1 week later indicated reliabilities ranging from .59 to .93 within all measures and across all assessment methods . Significantly high test-retest reliability coefficients support the use of these measures for research and clinical applications . Furthermore , no significant differences were found between assessment techniques , suggesting that Web-based methods are a suitable alternative to more traditional methods . This cost-efficient alternative has the advantage of minimizing data collection and entry errors while increasing survey accessibility
