Evaluating internet information on attention-deficit/hyperactivity disorder (ADHD) treatment: Parent and expert perspectives

BACKGROUND: The Internet is increasingly used as a source of health-related information. The objective of this study was to assess the quality of web-based information on treatments for attention-deficit/hyperactivity disorder (ADHD). METHODS: Sixteen expert health professionals in ADHD and 35 parents of paediatric patients with a recent diagnosis of ADHD assessed the information contained in the 10 highest ranked websites in Spanish, using the Spanish version of the DISCERN tool - a validated questionnaire designed to assess the quality and reliability of web-based information on treatment choices (rating scores from 15 to 75). RESULTS: DISCERN scores given by parents and experts were low (total mean scores [standard deviation]: 35.9 [13.1] and 43.4 [13.7], respectively) and inter-rater agreement was poor/moderate (weighted kappa for the global assessment between -0.69 and +0.93, average = 0.29). There was a significant change on the ADHD-knowledge and motivation for treatment (ADHD-KMT) basic knowledge sub-scale score after the assessment of the different websites by parents (total mean scores [standard deviation]: 49.09 [9.46] and 63.21 [9.45]). CONCLUSIONS: Despite a poor/moderate inter-rater agreement between parent and expert opinions, all agreed that the quality of the web-based information on treatment choices for ADHD is generally poor.
