Protection Motivation Theory and Contingent Valuation: Perceived Realism, Threat and WTP Estimates for Biodiversity Protection
We report on a discrete-choice CV study conducted in Germany to value the WTP for biodiversity protection in less developed countries. To systematically investigate survey realism and subjective threat assessment from the loss of biodiversity described in the scenario the study includes questions to uncover the constructs of Protection Motivation Theory, which is introduced to the CV literature. The patterns of responses to such questions are analysed using an Expectation-Maximization algorithm to derive class membership probabilities. These are found to match the predictions of Protection Motivation Theory and systematically improve the logistic analysis of the WTP responses.Biodiversity valuation, Protection motivation theory, Latent class analysis, Expectation-Maximization algorithm, Contingent valuation
Systematic review of communication technologies to promote access and engagement of young people with diabetes into healthcare
Background: Research has investigated whether communication technologies (e.g. mobile telephony, forums,
email) can be used to transfer digital information between healthcare professionals and young people who live
with diabetes. The systematic review evaluates the effectiveness and impact of these technologies on
communication.
Methods: Nine electronic databases were searched. Technologies were described and a narrative synthesis of all
studies was undertaken.
Results: Of 20,925 publications identified, 19 met the inclusion criteria, with 18 technologies assessed. Five
categories of communication technologies were identified: video-and tele-conferencing (n = 2); mobile telephony
(n = 3); telephone support (n = 3); novel electronic communication devices for transferring clinical information (n =
10); and web-based discussion boards (n = 1). Ten studies showed a positive improvement in HbA1c following the
intervention with four studies reporting detrimental increases in HbA1c levels. In fifteen studies communication
technologies increased the frequency of contact between patient and healthcare professional. Findings were
inconsistent of an association between improvements in HbA1c and increased contact. Limited evidence was
available concerning behavioural and care coordination outcomes, although improvement in quality of life, patientcaregiver
interaction, self-care and metabolic transmission were reported for some communication technologies.
Conclusions: The breadth of study design and types of technologies reported make the magnitude of benefit and
their effects on health difficult to determine. While communication technologies may increase the frequency of
contact between patient and health care professional, it remains unclear whether this results in improved
outcomes and is often the basis of the intervention itself. Further research is needed to explore the effectiveness
and cost effectiveness of increasing the use of communication technologies between young people and
healthcare professionals
