Reproducibility is one criterion for progress in science. If a study is repeated under similar conditions, then it should be possible to obtain the same findings. However, journal reviewers and editors may not accept a replication or failed replication for publication on the grounds that it is not as ‘newsworthy’ as an original study. In one landmark study, fewer than half of 100 studies published in 2008 in three top psychology journals could be successfully replicated (Open Science Collaboration, 2015). Lack of replication indicates that: (1) Study A’s results may be false, or (2) Study B’s results may be false, or (3) both may be false, or (4) there may be some subtle differences in the way the two studies were conducted – in other words, there were differences in the context. The OSC analysis showed that a low p value was predictive of which studies could be replicated. Twenty of the 32 original studies with a p < 0.001 could be replicated, while only 2 of the 11 papers with a value greater than 0.04 were successfully replicated. The reproducibility of health psychology studies is yet to be fully evaluated.
