Check on stuff that you think some things you think are healthy are actually, got a lot more sugar content than you expected. Engaged parent, school 16 However, 18 parents reported some negative feelings towards certain aspects of the programme in their questionnaire responses. One parent, who felt that their child was a fussy eater, had a smaller range of foods to choose from as he wanted to cut down on less healthy options. One parent felt that it was the responsibility of the parents to educate their children about physical activity and health. A small number of data from teachers also suggested that a few parents were less engaged with the programme. Two teachers from two different schools reported disappointing parental attendence, and in one school (school 7) a teacher informally reported to the HeLP co-ordinator that a parent had talked to the teaching assistant about not wanting to be lectured at about how to look after her child. Another teacher from a different school (school 9) reported that she had heard from a minority of children that their parents had thrown the project leaflets in the bin. School engagement School engagement scores ranged from 9 (maximum score) to 2. Characteristics of the less engaged schools included lack of senior leadership within the school generally, absent teacher during of the drama workshops and absent Year 5 teacher owing to illness during phases of the programme. There was nothing to suggest that variation in school engagement was linked to differences in school context, or school characteristics and policies as assessed by the School Characteristics and Policies Questionnaire (see Appendix 16).

Whereas phase 1 and phase 2 of the HeLP intervention focused on introducing the messages and engaging children and parents with how changes could be made using the creative delivery methods discussed in Chapter 2 (see Study design, Intervention), phase 3 focused on the children setting personalised goals around the key messages. Children were encouraged to set three goals based on snacking, fizzy drink consumption and physical activity, depending on the area in which they needed to make changes. Table 42 shows the number and percentage of goals set for each target behaviour by gender. As Table 42 shows, the majority of goals set by both genders were focused on increasing their physical activity and snacking. No marked differences were observed in the type of goal set by gender or engagement. Children reported mixed feelings about setting goals, with some finding it easy and others finding it more challenging for various reasons: I felt setting the goals, um one of my goals is really easy to set but the other two were really hard.
