Table 1 Inclusion criteria

From: Technology-based interventions for tobacco and other drug use in university and college students: a systematic review and meta-analysis

Stage 1 inclusion criteria
1 The study investigated an intervention for tobacco or other drug use.
2 The intervention was either disseminated via or accessed using a technological device (e.g., computer, smart phone, telephone) or process (e.g., e-mail, internet, SMS, video).
3 The study was conducted in a tertiary (university/college) setting with students or young people.
4 The article was in English.
Stage 2 Inclusion criteria
1 Study design – the study was a randomized controlled trial (RCT) or a randomized trial (RT, i.e. an equivalence trial).
2 Recruitment population – the sample was composed of students attending a tertiary institution (e.g., university, college).
3 Intervention type – the intervention (or some portion of the intervention; e.g., reminder or follow-up contact) was either delivered by or accessed using a technological device or process (internet, telephone, video). Studies that used technology to conduct screening or outcome measurement only (that is not considered part of the intervention) did not satisfy this criterion.
4 Age – the age range of the sample was between 18 and 25 years, OR the mean age of the sample was between 18 and 25 years (including up to 25.9 years).
5 Intervention focus – the intervention was designed to alter a drug use outcome relating to tobacco or other drug use and excluding alcohol (e.g., abstinence, intentions).
