About this study
The iSTART intervention is a 30-day substance prevention web-app whereby students complete five weekly interactive modules using a smart device or computer. Each module is approximately 15 minutes long, and focuses on a select substance: (i) alcohol, (ii) marijuana, (iii) nicotine, (iv) prescription drugs, and (v) illicit drugs. The modules are based on key theoretical constructs, behavior change strategies, and practical module components: attitudes (knowledge), perceived susceptibility (risk perceptions), subjective norms (normative re-education), and self-efficacy (refusal skills). This intervention will be evaluated via a time series design using a sample of 600 students randomly assigned to either the intervention, comparison, or control condition at a public institution in southern California.

iSTART Web-appBehavioural
30-day substance prevention web-app for students at a Hispanic Serving Institution.
| Study group | Role | What they receive |
|---|---|---|
| Prevention Group | Experimental | Web-app with five weekly substance modules. Each module is approximately 15 minutes long. Receives: Behavioral: iSTART Web-app |

| Control Group | No intervention | No access to web-app. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline alcohol use behavior at 3 months.
Measured as the number of days drinking alcohol in past 30-days
Measured: Baseline and 90-days following intervention completion.
Change from baseline binge drinking at 3 months.
Measured as the number of days consumed five or more alcoholic beverages at the same time for males; four or more for females in past 30-days.
Measured: Baseline and 90-days following intervention completion.
Change from baseline tobacco use at 3 months.
Measured as the number of days using cigarettes, pipe tobacco, chewing tobacco, snus in past 30-days.
Measured: Baseline and 90-days following intervention completion.
Change from baseline electronic vaping at 3 months.
Measured as the number of days vaped in past 30-days.
Measured: Baseline and 90-days following intervention completion.
Change from baseline marijuana use at 3 months.
Measured as the number of days smoked marijuana in past 30-days.
Measured: Baseline and 90-days following intervention completion.
Change from baseline non-prescribed prescription drug use at 3 months.
Measured as the number of days used stimulants, sedatives, benzodiazepines, and prescription opioids in past 30-days.
Measured: Baseline and 90-days following intervention completion.
Change from baseline illicit drug use at 3 months.
Measured as the number of days used cocaine, amphetamines, MDMA/Ecstasy, heroin, fentanyl, and non-Rx opioids in past 30-days.
Measured: Baseline and 90-days following intervention completion.
Secondary outcomes (2)
Change from baseline behavioral intent at 3 months.
Measured as the intent to smoke marijuana/cigarettes, binge drink, and use non-prescribed drugs. Participants are asked to rate the likelihood of use in the next 30 days on a four-point Likert scale from 1=very likely to 4=very unlikely.
Measured: Baseline and 90-days following intervention completion.
Change from baseline alcohol-specific outcomes at 3 months.
Measured as participants who report any past 30-day alcohol use indicate how many times they have experienced ten select outcomes in the last 30 days while drinking alcohol, or as the result of their alcohol use. Example items include: 'Not being able to do your homework or study for a test', 'Missed out on other things because you spent too much money on alcohol', 'Went to work or school high or drunk', 'Felt that you needed more alcohol than you used to use in order to get the same effect', and 'Had withdrawal symptoms, that is, felt sick because you stopped or cut down on drinking'. Participants respond: 'never', '1-2 times', '3-5 times', '6-10 times', and 'more than 10 times' in the past 30-days.
Measured: Baseline and 90-days following intervention completion.
