“…Schools have long been a target of agencies and social institutions especially by those with a focus on health. A sampling of health intervention research includes mental health and bullying (Wells et al, 2003;Vreeman and Carroll, 2007;Durlak et al, 2011); social and emotional health (Bond et al, 2004;Patton et al, 2006); diet, exercise and obesity (PeÂrez-Rodrigo and Aranceta, 2001;Sahota et al, 2001;Bauer et al, 2004;Shepherd et al, 2006;Stice et al, 2006;Sharma, 2006;Brown and Summerbell, 2009;Shaya et al, 2008;Harris et al, 2009), harm minimisation (McBride et al, 2004, drug and alcohol (Cuijpers, 2002;Dusenbury et al, 2003) and peer-led vs adult-lead health education (Mellanby et al, 2000). In addition to an intervention approach to specific health problems or illnesses there is also evaluation of interventions for their fidelity to implementation process, pre-determined outcomes, programme achievements and challenges for sustainability beyond the intervention and surveillance period (Durlak and DuPre, 2008).…”
