Evidence-Based Criteria (Silverman & Hinshaw, 2008)

Criteria 1: Well-Established Treatment	Criteria 2: Probably Efficacious Treatments	Criterion 3: Possibly Efficacious Treatments	Criterion 4: Experimental Treatments
1.1 There must be at least two good group-design experiments, conducted in at least two independent research settings and by independent investigatory teams, demonstrating efficacy by showing the treatment to be: a) statistically significantly superior to pill or psychological placebo or to another treatment OR b) equivalent (or not significantly different) to an already established treatment in experiments with statistical power being sufficient to detect moderate differences	2.1 There must be at least two good experiments showing the treatment is superior (statistically significantly so) to a wait-list control group OR Criteria 2.2 2.2 One or more good experiments meeting the Well-Established Treatment Criteria with the one exception of having been conducted in at least two independent research settings and by independent investigatory teams	At least one “good” study showing the treatment to be efficacious in the absence of conflicting evidence	Treatment not yet tested in trials meeting task force criteria for methodology
1.2 Treatment manuals or logical equivalent were used for the treatment
1.3 Conducted with a population, treated for specified problems, for whom inclusion criteria have been delineated in a reliable, valid manner
1.4 Reliable and valid outcome assessment measures, at minimum tapping the problems targeted for change were used
1.5 Appropriate data analyses
