This study systematically reviewed the evidence on interventions seeking to improve Food and Nutrition Literacy (FNLIT) functional, interactive and critical skills in primary school-aged children. Electronic databases, including PubMed/MEDLINE, SCOPUS, Web of Science, Cochrane, Pro-Quest and Google Scholar were systematically searched. Randomised and non-randomised controlled trials, pre-/post-test and case–control designs were included. The primary outcomes were three levels of FNLIT: functional, interactive and critical. All citations, full-text articles and abstract data were screened by two independent reviewers. Any conflicts were then resolved through discussion. The quality of the included studies was individually evaluated using the Effective Public Health Practice Project (EPHPP) quality assessment tool. Two reviewers extracted data from the included studies, and a descriptive analysis was performed. The quality of all eligible studies (n 19) was rated as moderate/weak. A wide variety of skill-building activities were introduced by programmes, including recipe skills/food preparation, food label literacy, food tasting, gardening harvesting, and supporting cultural practices and ethnic foods. Only four studies measured food literacy (FL) (food label literacy) via a valid measure. Most interventions focused on the functional level of FL, except for two programmes (one scored weak and one scored moderate). In most of the studies, delivery of intervention content was facilitated by teachers (n 15). Promising interventions were tailored to the needs and interests of students, incorporated into the existing curriculum and facilitated by teachers. The successful intervention strategies led to improvements in functional, partly interactive and critical skills. Future interventions should focus, holistically, on all aspects of FNLIT, especially interactive and critical skills.

School-based studies, despite the large number of studies conducted, have reported inconclusive results on obesity prevention. The sample size is a major constraint in such studies by requiring large samples. This pooled analysis overcomes this problem by analysing 5926 students (mean age 11·5 years) from five randomised school-based interventions. These studies focused on encouraging students to change their drinking and eating habits, and physical activities over the one school year, with monthly 1-h sessions in the classroom; culinary class aimed at developing cooking skills to increase healthy eating and attempts to family engagement. Pooled intention-to-treat analysis using linear mixed models accounted for school clusters. Control and intervention groups were balanced at baseline. The overall result was a non-significant change in BMI after one school year of positive changes in behaviours associated with obesity. Estimated mean BMI changed from 19·02 to 19·22 kg/m2 in the control group and from 19·08 to 19·32 kg/m2 in the intervention group (P value of change over time = 0·09). Subgroup analyses among those overweight or with obesity at baseline also did not show differences between intervention and control groups. The percentage of fat measured by bioimpedance indicated a small reduction in the control compared with intervention (P = 0·05). This large pooled analysis showed no effect on obesity measures, although promising results were observed about modifying behaviours associated with obesity.

Strategies are needed to improve the dietary habits of children. The aim of the present study was to evaluate the effect of implementing a school food programme on the dietary quality of lunches consumed by school children aged 7–13 years compared with packed lunches brought from home. A secondary objective was to investigate if a possible effect would differ between the younger children and the older. A quasi-experimental study design with four intervention schools and four matched control schools was conducted. In total, 984 school children participated. Data on packed lunches were collected at baseline. At the 1st follow-up the children in the intervention schools were offered free school meals and at the 2nd follow-up children paid for their school meals. The control group had packed lunches at all measurements. A digital photographic method combined with a Meal Index of dietary Quality (Meal IQ) was used for dietary assessment. Multilevel modelling was employed for data analyses. The quality of dietary intake was improved when free school meals were offered (P = 0·004); if the school meals were paid for the use was limited and no difference in change in dietary quality was found (P = 0·343). The school food programme had no difference in effect according to age (P = 0·083). In conclusion, offering a free school meal had a positive effect on dietary quality of the lunches consumed by school children aged 7–13 years. No effect was measured when the school meals were not provided for free. The dietary effect did not depend on age.

In recent years, researchers have worked closely with parents, teachers, other school staff, and external stakeholders to increase knowledge on ways to effectively teach children and adolescents with disabilities in mainstream school settings. State, national, and global directives have encouraged the implementation of research-based practices and contributed to advocacy efforts for students with and without disabilities. In a longitudinal comparative case study, Grima-Farrell (2017) responded to these movements by striving to enhance teacher knowledge on how to effectively implement and sustain the use of validated teaching approaches to maximise the student engagement and success of all students. This paper specifically reports on the school-based efforts of 6 experienced teachers as they strive to implement research-based practices to respond to the diverse needs of their students. Results are presented using the research-to-practice model (Grima-Farrell, 2017) as a conceptual framework for guiding instructional decision-making through the implementation and sustained use of validated educational research approaches.

In this qualitative study, we explored the perspectives of 10 adolescents with a diagnosis of autism spectrum disorder (ASD) and their experiences of bullying. Through individual semistructured interviews, they were asked to describe their understandings and experiences of bullying. Details of their experiences are described as well as the perceived impact on the students and their schooling. Data analysis revealed a number of common experiences including high rates of traditional bullying and more specifically verbal bullying, with fewer incidents of cyberbullying reported. In support of literature in the area, the results of the study indicate that bullying can be a significant inhibitor, which may prevent students with ASD from taking full advantage of their schooling. Listening to and reflecting on the voices and personal stories of adolescent students with ASD is critically important for developing more supportive approaches to their education and needs. The reports of bullying by students on the autism spectrum emphasises the need for more effective interventions and management strategies to be implemented in a whole-school approach as well as targeted strategies to prevent bullying experiences for this particular population of students.

Purpose: There is limited research on the costs of social and emotional learning (SEL) interventions [Crowley, Jones, Greenberg, Feinberg & Spoth (2012). Resource Consumption of a Diffusion Model for Prevention Programs: The PROSPER Delivery System. Journal of Adolescent Health, 50 (3), 256–263]. This paper describes a comprehensive methodology for determining the costs of a successful universal, school-based SEL intervention that was implemented in nine public schools over 3 years.

Methods: Resource costs were identified using the Cost–Procedure–Process–Outcome Analysis Model [Yates (1996). Analyzing Costs, Procedures, Processes, and Outcomes in Human Services. Thousand Oaks, CA, US: Sage Publications, Inc.; Yates (1999). Measuring and Improving Cost, Cost-Effectiveness, and Cost-Benefit for Substance Abuse Treatment Programs. No. NIH 99-4518, 135] and the ingredients model [Levin (Ed.) (1983). Cost-Effectiveness A Primer (Vol. 4). Beverly Hills, CA: Sage; Levin & McEwan (2001). Cost-Effectiveness Analysis: Methods and Applications. (2nd ed.). Thousand Oaks, CA: Sage Publications]. This involved careful identification of resource use, finding the cost per unit for each resource by intervention activity, and ultimately calculating the total resource cost (resource use $\times$ cost per unit).

Results: Our analysis estimated the overall cost of this 3-year SEL and literacy intervention to be $1,831,296 for nine schools. This averages to $67,825 yearly per school and $130 yearly for each student. The analysis estimated the first year of the intervention to be the costliest ($683,106) and then decreasing in Year 2 ($581,764) and Year 3 ($566,426).

Conclusion: This research emphasizes the need to study the costs of SEL interventions. By providing a detailed and standardized methodology, this cost analysis can provide added support for implementing an effective social and emotional learning intervention in a school setting. Furthermore, it provides groundwork for more advanced cost analyses, such as a cost–effectiveness analysis or a benefit-cost analysis (BCA).

Little is known about the mediating effects of the determinants of fruit and vegetable (FV) intake in school-based interventions that promote FV intake, and few studies have examined the impact of the degree of implementation on the effects of an intervention. The present study examined whether the degree of implementation of an intervention had an effect on children's fruit or vegetable intake and determined possible mediators of this effect. The study is part of the European PRO GREENS intervention study which aimed to develop effective strategies to promote consumption of fruit and vegetables in schoolchildren across Europe. Data from 727 Finnish children aged 11 years were used. The baseline study was conducted in spring 2009 and the follow-up study 12 months later. The intervention was conducted during the school year 2009–2010. The effects were examined using multilevel mediation analyses. A high degree of implementation of the intervention had an effect on children's fruit intake. Knowledge of recommendations for FV intake and liking mediated the association between a high degree of implementation of the intervention and an increase in the frequency of fruit intake. Knowledge of recommendations for FV intake and bringing fruits to school as a snack mediated the association between a low degree of implementation of the intervention and an increase in the frequency of fruit intake. Overall, the model accounted for 34 % of the variance in the change in fruit intake frequency. Knowledge of recommendations acted as a mediator between the degree of implementation of the intervention and the change in vegetable intake frequency. In conclusion, the degree of implementation had an effect on fruit intake, and thus in future intervention studies the actual degree of implementation of interventions should be assessed when considering the effects of interventions.

This study used depression (CDI – Kovacs, 1981), anxiety (MASC – March, 1997) and coping strategy (CRI-Y – Moos, 1993) scales and studied the fitness and discriminant validity of reduced versions. The sample consisted of 916 Portuguese pupils, 54.3% feminine, aged 10 to 21 years old. The participants were selected from a set of public schools nation-wide. Two classes were chosen from the 5th to the 12th grades.

A set of principal component analyses was carried out in a randomly chosen sample (n = 394) and all the three reduced measures were found to be strongly correlated with the previous. Confirmatory factor analyses (CFA) using the other part of the sample (n = 522) revealed adjustment indexes suggesting a good fit for both the whole model and gender and age groups separately. All scales revealed a good internal consistency. Globally, girls were more anxious and developed more coping strategies than boys. Older students tended to be less depressed, while younger adolescents present higher scores in depression and anxiety and less coping strategies. Reduced scales are sensitive to gender and age differences and can be used in school settings in order to establish a baseline and roadmaps for both universal and selective mental health school based programs.

The objective of the present review was to summarise the existing European published and ‘grey’ literature on the effectiveness of school-based interventions to promote a healthy diet in children (6–12 years old) and adolescents (13–18 years old). Eight electronic databases, websites and contents of key journals were systematically searched, reference lists were screened, and authors and experts in the field were contacted for studies evaluating school-based interventions promoting a healthy diet and aiming at primary prevention of obesity. The studies were included if they were published between 1 January 1990 and 31 December 2007 and reported effects on dietary behaviour or on anthropometrics. Finally, forty-two studies met the inclusion criteria: twenty-nine in children and thirteen in adolescents. In children, strong evidence of effect was found for multicomponent interventions on fruit and vegetable intakes. Limited evidence of effect was found for educational interventions on behaviour, and for environmental interventions on fruit and vegetable intakes. Interventions that specifically targeted children from lower socio-economic status groups showed limited evidence of effect on behaviour. In adolescents, moderate evidence of effect was found for educational interventions on behaviour and limited evidence of effect for multicomponent programmes on behaviour. In children and adolescents, effects on anthropometrics were often not measured, and therefore evidence was lacking or delivered inconclusive evidence. To conclude, evidence was found for the effectiveness of especially multicomponent interventions promoting a healthy diet in school-aged children in European Union countries on self-reported dietary behaviour. Evidence for effectiveness on anthropometrical obesity-related measures is lacking.

The objective of the present study was to evaluate the effects of the Pro Children intervention on schoolchildren's fruit and vegetable (FV) intake after 1 and 2 years of follow-up. The intervention combined a FV curriculum with efforts to improve FV availability at schools and at home. Effects were examined in a group-randomised trial among 1472 10–11-year-old children from sixty-two schools in Norway, the Netherlands and Spain. FV intake was assessed by means of validated self-administered questionnaires completed before the intervention (September 2003), immediately after the first year of the intervention (May 2004) and 1 year later (May 2005). Data were analysed using multilevel linear regression analyses with age and sex as covariates. Significant intervention effects for FV intake were found at first follow-up in the total sample. The adjusted FV intake reported by the children from intervention schools was 20 % higher than FV intake reported by children from control schools. At 1 year later, a significant impact was only observed in Norway. Positive intervention effects on FV intake occurred both at school and outside school. We conclude that the Pro Children intervention is a promising means to promote European schoolchildren's FV intakes, but mainly fruit intake, in the short term. As shown in Norway, where the intervention was best implemented, the intervention might also result in longer-term effects. Further strategies need to be developed that can improve implementation, have an impact on vegetable intake and can secure sustained effects.
