Communicating written information about medicines : the effects of benefit information on people's judgements
Although consumers want to be given information about the risks and benefits of medical lent, more research is needed to examine the effects of providing benefit information. The present thesis aims to assess the effects of communicating written benefit information about a medicine, and to determine how the additional benefit information affects people's judgements and intentions to carry out a health behaviour. There are nine experiments in total, organised in five chapters (chapters 3-7). All experiments are q questionnaire-based. presenting non-patient participants with a hypothedcal scenario about being diagnosed with a disease by the doctor, being prescribed a medicine, and being provided with information about the medicine. People are then asked to answer several questions, where they judge the information along several dimensions by means of Likert scales.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Official warnings on thromboembolism risk with oral contraceptives fail to inform users adequately
Following the 1995 “pill scare” relating to the risk of venous thrombosis from taking second- or third-generation oral contraceptives, the Committee on Safety of Medicines (CSM) withdrew their earlier recommended restrictions on the use of third-generation pills and published recommended wording to be used in patient information leaflets. However, the effectiveness of this wording has not been tested. An empirical study (with 186 pill users, past users, and non-users) was conducted to assess understanding, based on this wording, of the absolute and relative risk of thrombosis in pill users and in pregnancy. The results showed that less than 12% of women in the (higher education) group fully understood the absolute levels of risk from taking the pill and from being pregnant. Relative risk was also poorly understood, with less than 40% of participants showing full understanding, and 20% showing no understanding. We recommend that the CSM revisit the wording currently provided to millions of women in the UK

The benefits of providing benefit information: examining the effectiveness of provision of simple benefit statements on people's judgements about a medicine
Three experiments examined the effects of adding information about medication benefits to a short written explanation about a medicine. Participants were presented with a fictitious scenario about visiting the doctor, being prescribed an antibiotic and being given information about the medicine. They were asked to make various judgements relating to the information, the medicine and their intention to take it. Experiment 1 found that information about benefits enhanced the judgements, but did not influence the intention to comply. Experiment 2 compared the relative effectiveness of two different forms of the benefit statement, and found that both were effective in improving judgements, but had no effect on intention to comply. Experiment 3 compared the effectiveness of the two forms of benefit information but participants were told that the medicine was associated with four named side effects. Both types of statement improved ratings of the intention to comply, as well as ratings on the other measures. The experiments provide fairly consistent support for the inclusion of benefit information in medicine information leaflets, particularly to balance concerns about side effects
