BLIND STUDIES

 

INTRODUCTION:  The concept of a double-blind study is very similar to that of a blind study except that it also tries to eliminate researcher bias by not disclosing to the researcher the identities of experimental, comparative and placebo groups. In a double-blind study neither the researcher nor the study participants know which study participants are receiving real, placebo or other forms of interventions. This prevents the possibility of introducing bias by the researcher, promoting maximum reliability of the study findings.
