| Description | Adaptation of SHAHRP (Schools Alcohol Harm Reduction Programme) and TATI (Talking to Children About Tough Issues) Alcohol Misuse Prevention Programme (STAMPP): a school based cluster randomised controlled trial. |
| Status | Closed |
| Date Opened to Recruitment | May 2012 |
| Target Recruitment | 105 schools |
| Recruitment to date | 105 schools – 11,317 pupils (Completed) |
| Trial Design | A randomised controlled cluster trial comparing STAMPP vs alcohol education as normal for the reduction of hazardous and harmful alcohol drinking and alcohol related harms. |
| Study Aim | The overall research question to be answered is: Is a classroom psychoeducational intervention with parental components (STAMPP) (cost) effective in reducing hazardous drinking and the harms associated with alcohol use in young people compared with alcohol education as usual (EAU)?This will be assessed by determining changes in several indicators of alcohol consumption, alcohol cognitions, and other alcohol related behaviour. Outcomes will be assessed using a variety of standardised and validated measures. |
| The primary research objective is:• To ascertain the effectiveness and cost-effectiveness of STAMPP in reducing alcohol consumption (self reported consumption of >5 drinks in a single episode in the previous 30 days) in second form pupils (aged at least 13 on the 1st September 2012) at + 18 months post intervention. This will be dichotomised at never/one or more occasions.
• To ascertain the effectiveness of STAMPP in reducing alcohol related harms as measured by the number of self-reported harms (harms caused by own drinking) in second form pupils (aged at least 13 on the 1st September 2012) at + 18 months post intervention |
|
| Secondary research objectives are:• To ascertain the effectiveness and cost-effectiveness of STAMPP in reducing alcohol consumption (frequency of consuming >5 drinks in a single episode in the previous 30 days) in second form pupils (aged at least 13 on the 1st September 2012) at + 6 months post intervention. This will be dichotomised at never/one or more occasion.
• To ascertain the effectiveness of STAMPP in reducing alcohol consumption (self-reported alcohol use in lifetime, last year and previous month; number of drinks in ‘typical’ and last use episodes; age of alcohol initiation, age of alcohol initiation, unsupervised drinking) in second form pupils (aged at least 13 on the 1st September 2012) at + 6 months post intervention and + 18 months post intervention. • To ascertain the effectiveness of STAMPP in reducing alcohol related harms as measured by health service utilisation and self-reported harms (harms caused by own drinking and that of others) in second form pupils (aged at least 13 on the 1st September 2012) at + 6 months post intervention and + 18 months post intervention. And, if shown to be effective: • To ascertain the behavioural and cognitive mediators of change (individual and family factors) that lead to the effectiveness of STAMPP in second form pupils (aged at least 13 on the 1st September 2012) at + 6 months post intervention and + 18 months post intervention. |
