www.learningbenefits.net Leon Feinstein 18-July-2006 Targeted and universal intervention
www.learningbenefits.net Five questions How well can we identify those children at risk of adult social exclusion? Which measures are most predictive? What difference does it make? What are the implications for the delivery of services? What are the implications for the targeting of interventions?

www.learningbenefits.net Some cost-benefit notation C(T+) = The social cost of the outcome (T=truth) P(T+) = The unconditional probability of the outcome P(D+)= The level of targeting of the intervention C(D+)= The cost of the intervention f= the effectiveness of the intervention; 0 f 1.
www.learningbenefits.net True and false positives Truth PositiveNegative Decision (Predicted outcome) PositiveTrue positive A False positive B NegativeFalse negative C True negative D P(TP) = P(D+ | T+) = A / (A+C) P(FP) = P(D+ | T-) = B / (B+D)
www.learningbenefits.net Costs and benefits C(T-, D+) = The cost of a positive decision and hence intervention for those who would not experience the outcome (deadweight +stigmatisation costs) C(T+, D-) = The cost of a negative decision and hence failure to intervene for those who would experience the outcome B(T+, D+) = The net benefit of a positive decision and intervention for those who would experience the outcome (net of intervention and stigmatisation costs) B(T-, D-) = The net benefit of a negative decision and absence of intervention for those who would not experience the outcome.

Preliminary discussion Targeting depends on identification Identification capabilities are very strong So targeted intervention is possible, but: Ethical issues Stigmatisation Need effective and appropriate intervention Facilitated community engagement crucial People move in and out of risk Progressive universalism is essential Role of schools and GPs?
