Abstract

Background: A large proportion of ill-health is preventable (Signorelli 1993). A goal for health promoters is to provide information about health risks with the aim of persuading individuals to modify their behaviour. Previous research suggests that the readability of many health promotion materials is too low for effective comprehension. Evidence suggests that much of the health information available is written at a level that is too difficult for the target populations (e.g. Dollahite et al. 1996, Meade & Byrd 1989, Greenfield et al. 2005). Whilst this work is useful in identifying barriers to accessibility to health information, there has been little research that systematically explores the concept of usability within the context of health information. Objectives: The first objective of the thesis was to examine whether the concepts of usability and usefulness as outlined in the Technology Acceptance Model (Davis 1993) can be applied to the domain of health promotion and used to predict intentions to follow the advice given in health promotion leaflets. Second, the studies sought to make distinctions between subjective and objective usability and to explore the factors underlying subjective ratings of the usability of health information. Further, the thesis sought to demonstrate that both objective and subjective usability would influence the persuasive effect of health promotion materials. Finally, using theory from dual-processing models of persuasion (e.g. Elaboration Likelihood Model. Petty and Cacioppo 1986) it was predicted that when usability of leaflets was high, participants would be more likely to make judgements about their intentions to follow the advice given in the leaflets based on peripheral clues such as frame (Tversky and Kahneman 1981, Rothman and Salovey 1997, Levin et al. 1998). Methodology: 5 empirical studies examined the research questions. The first study consisted of two samples from working populations (n=441), and explored manual handling and use of hearing protection. Participants evaluated existing health and safety leaflets in relations to their usability and usefulness, and rated their intentions to follow the advice in the leaflets. The second study, also conducted on a working population (n=97), used experimentally manipulated leaflets on safe manual handling to test the hypothesis that framing effects would be found when usability of leaflets was high. The third study used a student sample (n=127) to explore factors that influence subjective usability. The study used experimentally manipulated leaflets about safe alcohol consumption to examine whether the concept of subjective usability is a function of reader characteristics (psychological constructs, mood, past exposure to the health problem) and leaflet characteristics (frame, objective reading ease). The fourth study used a student sample (n=238) to test the effect of objective reading ease on recall, in order to test for differences in processing of two experimentally manipulated leaflets about safe alcohol consumption. It was predicted that easy leaflets would be processed at a more shallow level than difficult leaflets. The fifth study, also conducted on a student sample using experimentally manipulated safe alcohol leaflets (n= 135), used pre and post testing to further explore the effects of usability on framing effects, and to test for a moderating role of prior knowledge on the effect of usability on intentions. Results: The studies showed that readers distinguish two separate components to health information leaflets: usability and usefulness. Subjective perceptions of usability and perceived usefulness predicted intentions to follow the advice given in the leaflets. Objective usability (reading ease) influenced the persuasive effect of the leaflets, with easy leaflets being more persuasive than difficult leaflets. Perceived usefulness partially mediated the relationship between subjective usability and intentions. Objective reading ease affected recall, with easy leaflets resulting in higher levels of both accurate and false recall of the information in the leaflets. Prior knowledge moderated the relationship between usability and intentions. Those with low prior knowledge were more persuaded when usability was high. Usability influenced the effect of frame on intentions. Framing effects were only found where usability was high. Where framing effects were found, negative frame was more persuasive than positive frame, offering support for Levin et al.'s (1998) typology of framing effects. Conclusions: Results from the studies show that the concepts of usability and usefulness, formalised in models of technology acceptance (TAM), can be applied to health information and used to predict intentions to follow health promotion recommendations. A distinction can be made between subjective and objective usability, and both of these can influence persuasion. Using theory from dual-processing models of persuasion, usability of health information leaflets can influence the effect of frame on intentions to follow the health promotion advice.

Abstract

The authors omitted one hypoglycaemia-specific patientreported outcome measure (TRIM-HYPO) from their systematic review. The original article has now been corrected to include TRIM-HYPO. An incorrect entry in Table 5 for the HFS instrument has also been corrected. The overall conclusion has not changed.

Abstract

Purpose\ud \ud Persistent physical symptoms (PPS) are often associated with profound physical disability and psychological distress. Interventions for PPS that promote behavioural change aim to reduce levels of symptoms and improve overall functioning in patients. The evidence for these interventions is mixed, with effective relationships between patients and health practitioners (HPs) reported as the key to the success of primary care interventions. The objectives of this systematic review were to synthesize the qualitative evidence and to evaluate the acceptability of behavioural interventions for PPS in primary care, from the perspective of both patients and HPs.\ud \ud \ud Methods\ud \ud A comprehensive literature search was conducted in seven major electronic bibliographic databases, to February 2019. The aim was to identify a broad range of literature including, qualitative research, mixed methods research, and qualitative data embedded in trial reports or process evaluations. Fifty‐eight full papers were screened against the inclusion criteria. Nine studies were included and quality‐assessed. A qualitative evidence synthesis was conducted using thematic synthesis.\ud \ud \ud Results\ud \ud Some patients and HPs reported positive gains from taking part in or delivering interventions, with appropriate support and explanation of their symptoms important for patients. Barriers appeared to be underpinned by the relationship between the patients and HPs, and by beliefs and attitudes held by both parties.\ud \ud \ud Conclusions\ud \ud Patients should be provided with adequate information to make an informed decision about whether an intervention is appropriate for them, and interventions should not end suddenly or without adequate follow‐up. HPs should receive training and supervision to address their lack of confidence, and improve their knowledge of PPS.

Abstract

Abstract Background Personal statements and referees' reports are widely used on medical school application forms, particularly in the UK, to assess the suitability of candidates for a career in medicine. However there are few studies which assess the validity of such information for predicting unhappiness or dissatisfaction with a career in medicine. Here we combine data from a long-term prospective study of medical student selection and training, with an experimental approach in which a large number of assessors used a paired comparison technique to predict outcome. Methods Data from a large-scale prospective study of students applying to UK medical schools in 1990 were used to identify 40 pairs of doctors, matched by sex, for whom personal statements and referees' reports were available, and who in a 2002/3 follow-up study, one pair member was very satisfied and the other very dissatisfied with medicine as a career. In 2005, 96 assessors, who were experienced medical school selectors, doctors, medical students or psychology students, used information from the doctors' original applications to judge which member of each pair of doctors was the happier, more satisfied doctor. Results None of the groups of assessors were significantly different from chance expectations in using applicants' personal statements and the referees' reports to predict actual future satisfaction or dissatisfaction, the distribution being similar to binomial expectations. However judgements of pairs of application forms from pairs of doctors showed a non-binomial distribution, indicating consensus among assessors as to which doctor would be the happy doctor (although the consensus was wrong in half the cases). Assessors taking longer to do the task concurred more. Consensus judgements seem mainly to be based on referees' predictions of academic achievement (even though academic achievement is not actually a valid predictor of happiness or satisfaction). Conclusion Although widely used in medical student selection to assess motivation, interest and commitment to a medical career, the personal statement and the referee's report cannot validly be used by assessors, including experienced medical school selectors, to identify doctors who will subsequently be dissatisfied with a medical career.
