title: Randomised trial of the psychological effect of information about oral cancer in primary care settings.
abstract: OBJECTIVE
  To determine the immediate influence of a validated patient information leaflet (PIL) on patient anxiety and intention to have a screen for oral cancer in primary care attenders.
  
  
  METHODS
  Patients (n=800) attending their primary health care provider.
  
  
  METHODS
  Fourteen general practices (eight dental and six medical) in the northwest of England.
  
  
  METHODS
  Randomised controlled trial with two arms: leaflets provided in information group, leaflet was absent in control group.
  
  
  METHODS
  Single item ratings of (1) intention to have an oral cancer screen, and (2) anxiety towards a screen, (3) perceived risk of oral cancer. Knowledge of oral cancer, self-reported dental service attendance history and demographic variables were also collected.
  
  
  RESULTS
  Patients who had read the oral cancer PIL demonstrated an increase in their intention to have a screen (Mann Whitney U test: z=-3.67, P<0.001) and reduced anxiety (Mann Whitney U test: z=-2.07, P<0.05). Subjective risk was not elevated by the extra information. Intention to have a screen was predicted by knowledge level and anxiety (odds ratios: 1.10 and 0.70 respectively, both P's<0.001).
  
  
  CONCLUSIONS
  The influence of an information leaflet appeared to have a positive effect on anxiety level and intentions to agree to receive an oral cancer screen.
