Trial Outcomes & Findings for Randomized Controlled Trial of eScreen for Problematic Drug Use (NCT NCT01532388)

NCT ID: NCT01532388

Last Updated: 2023-11-13

Results Overview

The primary outcome measure for this trial was the total DUDIT score for the first four DUDIT questions at 3-month follow-up, as a measure of drug consumption only, referred to as the DUDIT-C.The DUDIT-C is a measure including the first four items of the DUDIT, with a minimum score of 0 and a maximum score of 16. Higher scores mean a worse outcome. Regarding the DUDIT-C, you will find information on it in the following articles. Please note that the analyses all refer to the same sample from a randomized controlled trial. Apart from the data in the two articles describing results from the current study, there are additional analyses shown in: Berman, A. H., Wennberg, P., \& Sinadinovic, K. (2015). Changes in Mental and Physical Well-Being Among Problematic Alcohol and Drug Users in 12-Month Internet-Based Intervention Trials. Psychology of Addictive Behaviors, 29(1), 97-105. doi: 10.1037/a0038420 A higher score means a worse outcome.

PRIMARY outcome

Timeframe: 3 months

Population: The analyses have been carried out according to both the Intention To Treat method (ITT) and according to Per protocols method (PP). Where possible, missing values were imputed with last observation carried backwards. In cases where no follow-up data were available, the last observation was carried forward.
