CONSORT-EHEALTH Checklist V1.6.2 Report

1b-i) Key features/functionalities/components of the intervention and comparator in the METHODS section of the ABSTRACT Like this: "This study evaluates the effectiveness of national provision of a brief online alcohol intervention for students in Sweden. Risky drinkers (n=1,605) at 9 colleges and universities in Sweden were identified using a single screening question. These students gave consent and were randomised into a two-arm parallel group RCT, consisting of immediate or delayed access to the intervention." 1b-ii) Level of human involvement in the METHODS section of the ABSTRACT Like this: "a fully automated online assessment and intervention with personalized feedback". 1b-iii) Open vs. closed, web-based (self-assessment) vs. face-to-face assessments in the METHODS section of the ABSTRACT Like this: "Risky drinkers (n=1,605) at 9 colleges and universities in Sweden were invited by mail and identified using a single screening question" 1b-iv) RESULTS section in abstract must contain use data Like this: Although there were some indications of possible benefit in sensitivity analyses, suggesting an intervention effect of a 10% reduction (95% CI 10 % increase to 30 % reduction) 1b-v) CONCLUSIONS/DISCUSSION in abstract for negative trials Like this: "Any effects of current national provision are likely to be small and further research and development work is needed to enhance effectiveness INTRODUCTION 2a-i) Problem and the type of system/solution Like this: "Existing evidence of the effectiveness of online interventions with students is mixed [6-8], partly because of unresolved methodological challenges including attrition prevention and assessment reactivity" 2a-ii) Scientific background, rationale: What is known about the (type of) system Like this: "Existing evidence of the effectiveness of online interventions with students is mixed [6-8], partly because of unresolved methodological challenges including attrition prevention and assessment reactivity" METHODS 3a) CONSORT: Description of trial design (such as parallel, factorial) including allocation ratio Like this: "AMADEUS-2 aims to provide a further evaluation of the national system for online alcohol intervention used in routine practice among the student health care centres in Sweden, specifically among the key target population of hazardous and harmful drinkers." 3b) CONSORT: Important changes to methods after trial commencement (such as eligibility criteria), with reasons No changes was done 3b-i) Bug fixes, Downtimes, Content Changes No change was made 4a) CONSORT: Eligibility criteria for participants Like thia " Students who were drinking twice a month or more often, 5 standard drinks (12 grams of alcohol in Sweden) or more for men or 4 standard drinks or more for women, were deemed eligible for trial participation. " 4a-i) Computer / Internet literacy No specified in this trials. Alla participants were young students who were thought to be use to computers. 4a-ii) Open vs. closed, web-based vs. face-to-face assessments: Like this: "All students in their 2nd, 4th or 6th terms (n=54,507) at the 9 colleges/universities were sent an e-mail in March 2013 inviting them to answer a single question about their drinking. If eligible for trial participation, they were provided with information permitting informed consent, making the present study unlike AMADEUS--1. " 4a-iii) Information giving during recruitment Like this: " All students in their 2nd, 4th or 6th terms (n=54,507) at the 9 colleges/universities were sent an e-mail in March 2013 inviting them to answer a single question about their drinking. If eligible for trial participation, they were provided with information permitting informed consent, making the present study unlike AMADEUS--1." 4b) CONSORT: Settings and locations where the data were collected Like this: "The study was undertaken in 9 of 26 student health care centres in Sweden, each providing services to one university or college. These centres were selected on the basis that they had not previously been involved in randomised controlled trials in our research programme" 4b-i) Report if outcomes were (self-)assessed through online questionnaires Like this: This study used a single 2-month follow-up assessment interval, after which the control group gained access to the intervention" 4b-ii) Report how institutional affiliations are displayed Like this: " The initial e-mail routinely sent from the participating student health care centre was altered so as to invite study participation" 5) CONSORT: Describe the interventions for each group with sufficient details to allow replication, including how and when they were actually administered 5-i) Mention names, credential, affiliations of the developers, sponsors, and owners
