“…The null findings for our planning intervention is contrary to the weight of evidence that has tended to support effects of planning interventions on health behaviour, including the relatively few studies that have applied these effects on medication adherence (Brown et al, 2009;Farmer et al, 2012;Jackson et al, 2006;Liu & Park, 2004;Lourenco et al, 2014;O'Carroll et al, 2014;Pakpour et al, 2015).
