Adolygiad Systematig
Mae'r awduron yn datgan. "To assess the effectiveness of early, computerized brief interventions on alcohol and cannabis use by young people aged 15 to 25 years who are high or risky consumers of either one or both of these substances by synthesizing data from randomized controlled trials."
Mae'r awduron yn datgan. "We included 60 studies that had randomized 33,316 participants in this review. Study characteristics: The studies were mostly from the United States and targeted high and risky alcohol use among university students. Bias/quality assessment: Some of the studies lacked clear descriptions of how the randomization sequence was generated and concealed. Many of the studies did not blind the participants. Some of the studies suffered from high loss to follow-up, and few studies had a pre-registered protocol. Findings: For alcohol, we found moderate quality evidence that multi-dose assessment and feedback was more effective than a single-dose assessment. We found low quality evidence that assessment and feedback might be more effective than no intervention. Assessment and feedback might also be more effective than assessment alone (low quality evidence). Short-term effects (< 6 months) were mostly larger than long-term (≥6 months) effects. For cannabis, we found that assessment and feedback might slightly reduce short-term consumption compared to no intervention. Adding feedback to assessment may have little or no effect on short-term cannabis consumption. Moreover, there may be little or no difference between assessment plus feedback and education on short-term and long-term cannabis consumption. Adverse effects: We did not find evidence of any adverse effects of the interventions."
Mae'r awduron yn datgan. "Computerized brief interventions are easy to administer, and the evidence from this review indicates that such brief interventions might reduce drinking for several months after the intervention. Additionally, there is no evidence for adverse effects. This means that brief, computerized interventions could be feasible ways of dealing with risky alcohol use among young people. The evidence on cannabis consumption is scarcer, suggesting the need for more research."
