CONDITIONS UNDER WHICH A BOGUS PIPELINE PROCEDURE ENHANCES THE VALIDITY OF SELF-REPORTED CIGARETTE-SMOKING - A META-ANALYTIC REVIEW

A meta-analysis was conducted to test whether the use of self-report m easures within the bogus pipeline (BPL) paradigm yields more valid res ponses than the use of self-report measures alone for assessing cigare tte smoking behavior. The meta-analytic results indicate that, overall , a BPL condition resulted in a larger proportion of subjects reportin g that they are frequent smokers, as compared to a self-report measure only (no pipeline) condition. Tests of categorical models indicate th at the enhanced validity of self-reports within the BPL paradigm is mo derated by the following variables: (a) type of BPL presentation emplo yed, (b) type of self-report measure to which the BPL technique is com pared, and (c) whether most participants are smokers (as indicated by a biochemical marker).
