A baseline model (model 1) for each subscale tested for generalisability of the final factor solutions reported to the 12-month data set (configural invariance) generic 500mg azulfidine. In this model generic 500 mg azulfidine with visa, the 12-month data set received separate factor loadings and error variances order azulfidine 500 mg with amex. In the next model (model 2) generic 500 mg azulfidine with mastercard, the factor loadings of the 12-month data set were fixed to the values estimated for the baseline data set. Comparing the fit between models 1 and 2 is thus a test of metric invariance. In other words, if model 2 does not provide a significantly improved fit (as assessed by a chi-squared difference test) compared with model 1, the factor loadings for the two data sets can be assumed to be equal. In the next step, invariance of error variation and the error term correlations was investigated. Model 3 fixed the general error variance and the values of error term correlations of the 12-month data set to the values for the baseline data set. Again, if there is no significant improvement compared with the preceding model (in this case model 2), residual invariance can be concluded. Results of invariance tests Confidence and motivation (items 6–14) The metric invariance test for the confidence and motivation subscale failed to demonstrate full metric invariance as the comparison of model 2 with model 1 was significant (Table 57). An inspection of the results of the CFA with the two data sets separately revealed a clear difference in the factor loading for item 10. For the baseline data set B, the factor loading of item 10 was 0. As a result, partial invariance was testing whereby only the factor loading of item 10 was allowed to vary between samples (model 2a). The fit of model 2a was not a significant improvement on model 1, confirming partial metric invariance. Last, residual invariance was confirmed through model 3.

APPENDIX 18 Peer norms (items 15–22) The metric invariance test for the peer norms subscale also failed to demonstrate full metric invariance as model 2 provided a significant improvement on model 1 (Table 58). An inspection of the results of the CFA with the two data sets separately revealed a clear difference in the factor loading for item 15. For the baseline data set B, the factor loading of item 15 was 0. As a result, partial invariance was testing whereby only the factor loading of item 15 was allowed to vary between samples (model 2a). The fit of model 2a did not provide a significant improvement on model 1, thereby confirming partial metric invariance. Last, residual invariance was confirmed through model 3. As in the above CFA conducted separately for the two data sets, the regression weight for item 15 was also low here, suggesting that it may be advisable to consider removing this item from the scale. Family approval/behaviours and child attitudes (items 23–32 without item 31) As with confidence and motivation and peer norms, the metric invariance test for the family approval/ behaviours and child attitudes subscale failed to demonstrate full metric invariance. As shown in Table 59, model 2 provided a significant improvement on model 1. An inspection of the results of the CFA with the two data sets separately revealed a clear difference in the factor loading for item 24.

Schools have been highlighted as providing a captive audience with the potential to access children across the socioeconomic spectrum; however cheap azulfidine 500 mg amex, few studies took a relational approach to both the intervention and the trial design purchase azulfidine 500 mg fast delivery, whereby the building of relationships with all participants to enhance engagement with the programme and the trial was a key focus in recruitment azulfidine 500 mg free shipping, data collection generic 500mg azulfidine with mastercard, and intervention design and delivery. Specifically, the design of the HeLP study ensured that (1) baseline measurements were collected before schools (and children) were allocated to the intervention or the control group; (2) a standardised objective measure with a significant follow-up time was utilised to assess obesity prevention (BMI SDS at 24 months); (3) an objective measure of physical activity, with evidence of high compliance, was used29 (GeneActiv activity monitor; www. During intervention delivery we ensured that (1) delivery personnel had the necessary skills and competencies to build relationships; (2) there was one key contact person per school who co-ordinated the research hand delivery (the HeLP co-ordinator); (3) the delivery methods used were suitably engaging and dynamic for the target group, so that the children would be motivated to take the messages home and initiate discussion with their family; (4) the intervention used strategies to enhance identification with, 4 NIHR Journals Library www. The intervention aimed to change behaviours both inside and outside the school environment; these measurements were concerned with behaviours across the week, including weekends. We aimed to capture physical activity data across the whole week for children at baseline and at 18-month follow-up. To support this aim, we used wrist-worn activity monitors (the GeneActiv accelerometer), as feasibility studies had demonstrated high rates of compliance with this monitor in this age group. Aim and objectives The aim of this cluster RCT was to determine the effectiveness and cost-effectiveness of HeLP in preventing overweight and obesity in children.

As the intervention was designed to be delivered in schools, a cluster design was used. Individual child measurements were collected at baseline, 12 months [My Lifestyle Questionnaire (MLQ) only, which assessed potential mediating variables], 18 months and 24 months (anthropometric only) post baseline. Alongside the evaluation of effectiveness, we carried out a parallel economic and process evaluation. Following the exploratory trial28 and after assessing delivery requirements, we decided to run the trial in two cohorts, each with the same number of intervention and control schools. All schools were recruited in spring 2012 and then allocated to cohort 1 (commencing the trial in September 2012) or cohort 2 (commencing the trial in September 2013). Ethics approval and research governance We obtained ethics approval for the trial from the Peninsula College of Medicine and Dentistry Research Ethics Committee (reference number 12/03/140) in March 2012. Research governance approval was obtained in June 2012 from our sponsor, the Royal Devon & Exeter NHS Foundation Trust (study number 1304762). A Trial Steering Committee (TSC) was composed and chaired by Professor Martin White (editor-in-chief of the Public Health Research programme), with five other independent members and the research and development director for the Royal Devon & Exeter NHS Trust as the research sponsor (see Appendix 1). After discussion at the first TSC meeting (5 November 2012), it was agreed that a Data Monitoring Committee was not necessary because the risk of harm was considered low and no interim analyses were planned. Stakeholder involvement The development of HeLP and the conduct of the trial benefited greatly from the extensive stakeholder involvement in both intervention and trial design. We worked with a group of teachers, head teachers, parents and children from the early piloting of HeLP27 who became our Project Advisory Group (PAG). We invited teachers and parents from our PAG to be partners on our research bids for both the exploratory28 and the definitive trial. Meetings were held when required and at times convenient to the group (usually 4–6 p. Our PAG members advised us on what was feasible and acceptable when taking behavioural and anthropometric measures from 9- to 10-year-old children, and how to communicate with parents about the research process so that they would (1) receive the information, (2) understand it and (3) feel that they were able to engage with the researchers if they had any concerns or queries. In addition, it was important for us to understand how best to recruit schools and engage teachers with both the programme and the trial. The head teacher in our PAG suggested that we recruit schools via a regional network of primary school heads (the Devon Association of Primary Headteachers) during one of their quarterly briefing sessions, and a teacher involved in the exploratory trial28 offered to talk to head teachers about her experiences of being involved in the programme during the session. Our PAG also supported the intervention development and delivery, providing invaluable feedback on possible intervention activities and delivery methods and ensuring that they were acceptable to and feasible for schools, children and their families. It was important that any intervention we developed did not widen existing health inequalities and had the potential to engage children and their families from across the socioeconomic spectrum.
