â® Are the specific instruments adequately described, and were they good choices, given the study purpose and study population? What exactly were the instruments?

Is there evidence in the report that the data collection methods produced data with high reliability and validity? What was the proof?



(Five points)

â® If an intervention occurred, was it adequately described and implemented? Did the majority of those assigned to the intervention group receive it? Was there evidence of fidelity to the intervention?
