Wilson, S. J., Tanner-Smith, E., & Lipsey, M. W. (2011). Dropout Prevention and Intervention Programs: Effects on School Completion and Dropout Among School-aged Children and Youth. 2011 SREE Conference. http://ies.ed.gov/ncee/wwc/reports/dropout/topic/#top doi:10.4073/csr.2011.8

q3 · i? · quant-synthesis · r2

Random-effects meta-regression across the coded studies (Table 2). The article reports unpublished status (p = .00) and method quality (p = .06) as method variables associated with smaller treatment differences; routine practice status was not significant (p = .94).

"The results of the regression analyses on the studies coded thus far find that unpublished research and higher quality methods produce significantly smaller treatment differences."
