    Purpose:
    School-based dietary interventions often include a parental component, but the degree of implementation is seldom reported. This study evaluated the implementation of six parental newsletters in the Boost study, a multicomponent school-randomized controlled trial targeting fruit and vegetable intake among year 7th graders (~13-year-olds) in school year 2010/11.
    Methods:
    Post-intervention questionnaire data from parents and teachers at 20 intervention schools were analysed descriptively. Process measures: Dose delivered: number of newsletters uploaded by teachers to the school’s website. Dose received: if parents had seen and read the newsletters. Appreciation: perceived usefulness of newsletters. Reach: dose received stratified by gender and parental occupational social class (OSC).
    Results:
    Questionnaires were completed by parents of 58.7% of the students (N=658) and by teachers at 18 out of 20 intervention schools. Dose delivered: 11 teachers (61.1%) uploaded all newsletters. Dose received: 65.5% of the parents had seen the newsletters; 49.2% had read at least one. Appreciation: 39.2% found the newsletters useful. Reach by OSC and gender: Among parents, 56.1% of high OSC, 46.8% of medium OSC, and 40.0% of low OSC had read at least one newsletter; 30.6% of mothers and 18.0% of fathers had read at least one newsletter.
    Conclusions:
    Parental involvement was challenged by the fact that all newsletters were not uploaded. Newsletters were read by only half of the parents, especially fathers and low OSC parents were difficult to reach. The findings may be subject to selection bias due to parent non-response. Strategies to improve parents’ participation in school-based interventions and surveys should be developed.
