A dataset containing estimated effect sizes, variances, and covariates from a meta-analysis of dropout prevention/intervention program effects, conducted by Wilson et al. (2011). Missing observations were imputed.
Format
A data frame with 385 rows and 18 variables:
- LOR1
log-odds ratio measuring the intervention effect
- varLOR
estimated sampling variance of the log-odds ratio
- studyID
unique identifier for each study
- studySample
unique identifier for each sample within a study
- study_design
study design (randomized, matched, or non-randomized and unmatched)
- outcome
outcome measure for the intervention effect is estimated (school dropout, school enrollment, graduation, graduation or GED receipt)
- evaluator_independence
degree of evaluator independence (independent, indirect but influential, involved in planning but not delivery, involved in delivery)
- implementation_quality
level of implementation quality (clear problems, possible problems, no apparent problems)
- program_site
Program delivery site (community, mixed, school classroom, school but outside of classroom)
- attrition
Overall attrition (proportion)
- group_equivalence
pretest group-equivalence log-odds ratio
- adjusted
adjusted or unadjusted data used to calculate intervention effect
- male_pct
proportion of the sample that is male
- white_pct
proportion of the sample that is white
- average_age
average age of the sample
- duration
program duration (in weeks)
- service_hrs
program contact hours per week
- big_study
indicator for the 32 studies with 3 or more effect sizes
