The HeLP co-ordinators carried out all parent interviews for their respective schools discount mycelex-g 100 mg online. These interviews were carried out between January and March 2014/15 purchase mycelex-g 100mg with mastercard, during the spring term, after the intervention had finished. Focus groups A selection of children from each school participated in a focus group that consisted of between six and eight children. The HeLP co-ordinator for the school carried out two or three focus groups per school, depending on school size. One focus group was carried out with children who were considered to be engaged and another was carried out with children considered to be less engaged children. Details of how these categories were given are presented in the following section (see Observations). The aim of the focus groups was to obtain detailed data on what children had learnt; whether or not they talked about healthy lifestyles at home with their family and peer group and what they discussed; what they thought about the programme and how they felt it differed from the usual curriculum; how they felt about choosing and working with a character like them; what it was like to try to set and achieve their goals; what strategies they used to help achieve their goals; and whether or not there had been any changes at a family level (see Appendix 13 for the focus group schedule). They were led by the HeLP co-ordinator for that school and facilitated by an additional HeLP co-ordinator, who took notes and supported the management of the group. To help children remember the details of the programme, visual cues were provided along with a short summary of the activities they participated in for each phase. Observations Observations of intervention components were carried out to obtain data on fidelity to form (i. To assess fidelity to form, a yes/no checklist was completed (by the HeLP co-ordinator) for all HeLP components to indicate whether or not a component had been delivered (see Appendix 14 for an example checklist). The key components observed to assess fidelity to function were the parent assembly (phase 1), the healthy lifestyles week (phase 2), the parent assembly (phase 3) and the class-delivered assembly (phase 4). To assess fidelity to function, a score between 1 and 10 was given for (1) delivery, (2) child responsiveness, (3) parent responsiveness and (4) teacher responsiveness for each of the four key components observed. At the beginning of data collection, the trial manager and the principal investigator independently scored fidelity to function for the parent assembly (phase 1) across three schools. Thereafter the majority of observations were carried out by the trial manager. The HeLP co-ordinator assessed the majority of the healthy lifestyle week components (phase 2) after they had carried out initial assessments alongside the trial manager. Once again, no discrepancies in scoring were observed (see Appendix 15 for an example checklist). Each HeLP co-ordinator also collected informal observational data, in the form of field notes (see below), for child and school engagement. The HeLP co-ordinator gave each child an engagement score between 0 and 3. The criteria for scoring were: l 0 = uninterested/unaware goals needed to be set l 1 = reluctant/needs a lot of prompting l 2 = enthusiastic and happy to chat about goals and how they will achieve them l 3 = very enthusiastic; has discussed goals at home and has clear strategies for achieving them. School-level engagement was assessed using three scores based on the HeLP co-ordinator interaction with and observations of the head teacher, the Year 5 teacher(s) and the school support staff. A score between 0 and 3 was given to each staff member: l 0 = unengaged/unco-operative l 1 = supportive l 2 = enthusiastic and supportive l 3 = very enthusiastic and used HeLP in other aspects of teaching/school activities. Field notes Each HeLP co-ordinator kept recorded notes in a diary of their informal interactions with and observations of staff and children during the intervention, which fed into their assessment of staff and child engagement. In addition, the HeLP co-ordinators recorded any unintended consequences of the programme.

PROCESS EVALUATION Registers of attendance The HeLP co-ordinator kept registers of attendance for all intervention components and for parental attendance at parental engagement events (i. The Year 5 teachers were asked to keep a register for each personal, social and health education lesson that they delivered during the healthy lifestyles week, which was given to the HeLP co-ordinator. Parental signature In phase 3 of the intervention, children were asked to set goals at home with their parents on a goal-setting pro forma before they had their one-to-one discussion with the HeLP co-ordinator. Parents were asked to sign the form once discussions had taken place. All goal-setting pro formas were collected by the HeLP co-ordinator following the one-to-one discussion, and a copy of the goals was sent back to each parent/carer. Analysis All qualitative and quantitative process data were analysed blind to trial outcome and, initially, analysed separately. The different data sources were then combined to address each research question. Details of the analyses and subsequent synthesis are described in the sections below. Data from registers, parent questionnaire and goal-setting sheets Child and parental attendance at events, parental signature on the goal-setting sheet and both quantitative and more open qualitative responses from the parent questionnaire were entered into a Microsoft Access® (2014 version, Microsoft Corporation, Redmond, WA, USA) database.

Training and development Respondents were presented with a scale from minimal to major training and development provision. Only 8% of respondents reported that there had been major initiatives to provide training and development (Figure 27). Figure 28 suggests, however, that there has been a decline in GP engagement with leadership in and around CCGs. Figure 20) have shown reason for an optimistic picture of clinical leadership in and around CCGs, Figure 28 shows a degree of pessimism. There was an overall view that GPs are now less engaged in leadership than they were previously. There was broad agreement that, increasingly, service redesign is being tackled above the CCG level and that co-ordinated commissioning across multiple CCGs was increasingly common.
