This study explored the impact of the peer support programme on pupils at Japanese technical high school for over 6 years. A total of 268 pupils (an intervention group 112; a control group 114) were invited for the study and the pupils of the intervention group were given peer support training and they joined its supporting activities. All the pupils were assessed three times by adopting IRS, RSES10 and GHQ28. The results showed that the programme seemed to give positive influences on the peer supporters in terms of IRS, RSES10 and GHQ28. Also, both group members were classified into low-scoring groups and high-scoring groups, depending on their scores at the first assessment. Then, the results of analysis showed that the pupils from both low & high -scoring groups significantly improved their scores in IRS. In RSES10 and GHQ28, the pupils from the low-scoring groups improved their scores, but those from the high-scoring groups did not improve much. As a conclusion, even in a technical high school where the majority of pupils was male pupils (over 90%), the peer support programme seemed to give positive influences on the peer supporters in terms of IRS, RSES10 and GHQ28.  

This study aimed to explore how the peer support programme gave influences on technical high school pupils in Japan. The study invited a total 76 pupils (37 in an intervention group and 39 in a control group) to be involved into the peer support programme and assessments. The participants were annually assessed three times by adopting four scales, which examined their interpersonal relationship level, self-esteem, mental health, and school environmental adaptation states. The results showed that pupils in the intervention group (the peer supporters) tended to improve their own skills and abilities in terms of all the scales after joining the programme. Also, in terms of Adaptation Scale for School Environments on Six Spheres (ASSESS), which was a newly developed scale, there were no significant positive influences in both areas of “fulfillments in study” and “peer support activities against bullying”. As a conclusion, even in the technical high school where the majority of pupils were male, the peer support programme gave positive influences on the intervention group (the peer supporters) in terms of interpersonal relationship level, self-esteem, mental health, and school environmental adaptation states.
