title: Are attitudes towards medication adherence associated with medication adherence behaviours among patients with psychosis? A systematic review and meta analysis.
abstract: BACKGROUND
  Studies have shown patient attitudes to be an important predictor for health related behaviours including medication adherence. It is less clear whether patient attitudes are also associated with medication adherence among patients with psychoses.
  
  
  METHODS
  We conducted a systematic review and meta analysis of the data of studies that tested the association of attitude measures with medication adherence among patients with psychoses. 14 studies conducted between 1980 and 2010 were included.
  
  
  RESULTS
  Results show a small to moderate mean weighted effect size (r (+) = 0.25 and 0.26 for Pearson and Spearman correlations, respectively).
  
  
  CONCLUSIONS
  Theory based interventions that target potentially modifiable attitude components are needed to assess the relationship between positive patient attitudes and adherence behaviours among patients with psychoses.
