title: Barriers and facilitators for teachers' implementation of the curricular component of the boost intervention targeting adolescents' fruit and vegetable intake.
abstract: OBJECTIVE
  To examine barriers and facilitators to teachers' implementation of the curricular component of the school-based, multicomponent Boost intervention to promote fruit and vegetable intake among 13-year-olds guided by concepts of Diffusion of Innovations Theory and findings of previous implementation studies.
  
  
  METHODS
  Five focus group and 2 individual interviews.
  
  
  METHODS
  Denmark.
  
  
  METHODS
  Twenty-two seventh-grade teachers from 7 of 20 intervention schools. Four schools (15 teachers) with a high implementation level and 3 (7 teachers) with a low implementation level were selected to obtain maximum variation in teachers' view.
  
  
  METHODS
  Teacher perceptions of implementation of a curricular component.
  
  
  METHODS
  Situational Analysis including an introductory phase of systematic coding.
  
  
  RESULTS
  Teachers' commitment to the Boost curriculum was hindered by intervention duration and extra workload and motivated by a pre-intervention workshop and the thoroughness of the project. Detailed implementation manuals were helpful for some teachers but a barrier to others because they limited opportunities for adaptation.
  
  
  CONCLUSIONS
  Implementation of curricular activities in school-based interventions may be supported by a predefined teaching schedule, detailed teacher manuals, clear learning objectives, and a pre-intervention workshop to enhance motivation. Situational Analysis may contribute to future implementation studies by highlighting the importance of contextual factors.
