摘要: The proposition that an intervention without evidence of effectiveness for a targeted health problem should be continued to offered until such time with is available replace it problematic. persistence offerings has been identified as one type research-practice gap (McLennan, Wathen, MacMillan, & Lavis, 2006). Nevertheless, this appears the recommended approach suicide prevention suggested in editorial journal response review paper finding no compelling two marketed school-based programs, Signs Suicide (SOS) and Yellow Ribbon (YR) (Ickowicz Schachar, 2015; Wei, Kutcher, LeBlanc, 2015). More precisely, concluded “rejection initiatives under scrutiny would only justified when if something better can offered” (p.4, Ickowicz While understandable why wants do order address issue serious suicide, may counterproductive continue supporting failed demonstrate effectiveness. The authors raise potential adverse impacts from rejecting interventions One concern hidden within group null effect are some children benefit given intervention. However, case, overall then reflect few who might actually counterbalanced by harmed intervention, assuming study adequately powered. It certainly possible underpowered studies or otherwise flawed miss true positive effects, example Type II error. error also go other way missed. It could argued effects secondary participation more problematic than treatment existing disorder latter situation willing take on greater risk alleviation suffering whereas harm come someone pre-existing condition. Despite there be, paradoxically, lower standard offering perhaps driven belief “it can’t hurt” “better nothing.” Certainly very challenging conduct typical need look at small differences among large samples followed over significant periods time. Perhaps these demands lead apparent waiver for, least limited of, prior their dissemination. Even direct comes interventions, consequences still through opportunity costs. Opportunity cost, fundamental economic concept, means “by choosing use resources way, we forgo opportunities same resources” (p. 153; Gafni Birch, 2003). There real resource costs implementation including purchase training costs, ongoing personnel student staff have considered light how consumed (or be) used what effect. A net not free.
