---|---|---|---|
Murphy et al., (2019) | Brief alcohol intervention + substance free activity (BMI + SFAS) Brief alcohol intervention + relaxation training (BMI + RT) |
The BMI + SFAS condition was associated with lower anxiety levels, lower substance use, and less substance use consequences. The BMI + RT condition was associated with lower anxiety levels, lower substance use, and less substance use consequences. Neither condition was associated with reduced depression individually | The BMI + SFAS condition was associated with lower anxiety levels at first and last follow-up, lower depression levels at last follow-up only, lower substance use at first follow-up only, and less substance use consequences at first follow-up only. The BMI + RT condition was associated with lower levels of substance use and substance use consequences at both first and last follow-up; no significant differences were found for depression or anxiety |
Deady et al., (2016) | CBT/MI-based online modularized intervention | The intervention was associated with lower substance use, depression, and anxiety levels at first follow-up, but these differences lost significance by the last follow-up | The intervention was associated with lower substance use, depression, and anxiety levels at first follow-up, but these differences lost significance by the last follow-up |
O'Leary-Barrett et al., (2016) | Personality targeted intervention | The intervention was associated with a significant main effect on binge drinking onset, depression, and anxiety, but not on the remainder of the substance use outcomes. Significant indirect effects were found for binge drinking frequency, problem drinking onset, and problem drinking frequency | Authors did not respond to requests for data needed to calculate effect sizes |
Sterling et al., (2019) | Intervention for mental health symptoms and substance use | The intervention was associated with lower substance use diagnoses relative to the control group at last follow-up, but not at first follow-up (where there was trend-level significance). No significant, positive effect of the intervention on mental health diagnoses was found overall, but rates of depression diagnoses differed between groups at 3-year follow-up | The intervention was associated with lower substance use diagnoses relative to the control group at last follow-up, but not at first follow-up (where there was trend-level significance). No significant, positive effect of the intervention on mental health diagnoses was found overall. Authors did not provide diagnosis-level data |
Andersson et al., (2017) | Phone-delivered brief personalized feedback | The intervention was associated with a significant reduction in anxiety relative to the control group. No significant, positive effect of the intervention on depression or substance use was found | The intervention was associated with a significant reduction in anxiety relative to the control group. No significant, positive effect of the intervention on depression or substance use was found |
Brown et al., (2015) | Motivational interviewing | The intervention was associated with longer latency to first substance use and fewer days of substance use per month, though the significance of the latter outcome attenuated across follow-ups. The intervention was not associated with a significant difference in alcohol use consequences, depression levels, or anxiety levels | No significant, positive effect of the intervention on mental health was found. Authors did not provide data needed to calculate effect sizes for substance use outcomes |
