The psychometric properties of the internet related problem scale: A pilot study

Armstrong et al. (International Journal of Human Computer Studies, 53:537-550, 2000) explored the relationship between problematic Internet use and self-esteem. They devised a questionnaire called the Internet Related Problem Scale (IRPS) in order to measure the level of problem an individual is having due to their Internet use. This questionnaire study further examined the psychometric properties of the IRPS. Participants were recruited through the Internet, yielding 79 valid responses (14 males and 65 females). Factor analysis of the IRPS revealed six factors-salience, negative effects, mood enhancement, productivity, loss of control, and lack of information. These factors showed good internal consistency and concurrent validity, with salience being the most reliable. The limitations to this study are also addressed. Despite these limitations, the findings do seem to suggest that the IRPS has good psychometric properties and can be used in future studies examining Internet addiction. © 2007 Springer Science+Business Media, LLC.
