Evaluating and improving multiple choice papers: true–false questions in public health medicine

Summary. The quality of a multiple true–false (MTF) examination paper in public health medicine for 149 clinical medical students was evaluated using predefined performance criteria to offer guidelines for improvement of such a paper. There were 35 questions, each with five true-false branches, and the performance of the overall best 25% of candidates was compared for individual items with that of the overall worst 25%. To improve discrimination between best and worst candidates, 60% of items needed changes, and several indicators were used to identify how, usually because the branch was too easy (26%), unpopular (16%) or too hard (10%). A number of guidelines for writing good MTF questions and for improving them are suggested. The inequity is illustrated of marking systems which do not allocate a negative mark for incorrect answers equal in size to the positive mark for correct ones, with zero for unanswered questions or 'don't know' answers.     

Measuring higher cognitive levels by multiple choice questions: a myth?

Available evidence is inconclusive as to the ability of multiple choice items to measure different taxonomic levels of the cognitive domain. The present study analysed the tests of the Examen de Synthèse for the years 1982, 1983 and 1984. Items used in the study were those for which a consensus was reached between three judges and committees for a given taxonomic level. The initial part of the study showed that judges do not classify items at random but according to a mental representation which is individual, personal and relatively stable. In examining results obtained by students, the study failed to show any significant difference in item difficulty or discrimination for items classified as measuring memorization, interpretation of data and problem-solving. Correlations between results (scores and ranks) obtained for items involving memorization and those obtained for items involving higher cognitive levels fail to show that different traits are measured. If further studies corroborate these results, then future efforts should be directed at developing other instruments to measure higher cognitive levels.     

Health insurance subsidies and deductible choice: Evidence from regional variation in subsidy schemes

The extent to which premium subsidies can influence health insurance choices is an open question. In this paper, we explore the regional variation in subsidy schemes in Switzerland, designed as either in-kind or cash transfers, to study their impact on the choice of health insurance deductibles. Using health survey data and a difference-in-differences methodology, we find that in-kind transfers increase the likelihood of choosing a low deductible plan by approximately 4 percentage points (or 7%). Our results indicate that the response to in-kind transfers is strongest among women, middle-aged and unmarried individuals, which we explain by differences in risk-taking behavior, health status, financial constraints, health insurance and financial literacy. We discuss our results in the light of potential extra-marginal effects on the demand for health care services, which are however not supported by our data.     

Using the discrete choice experimental design to investigate decision-making about pressure ulcer prevention by community nurses

This study investigates the preferences of senior community nurses who work as district nurse team leaders in selecting preventive care plans for elderly people at high risk of pressure ulcer formation. The discrete choice experiment (DCE) technique was used. Focus group work produced the following five attributes of nurse decision-making: 'ease of care plan management', 'impact of care plan on patient's lifestyle', 'speed of obtaining the equipment', 'affordability', 'evidence-based practice'. These were incorporated into a self-administered questionnaire, posted to 102 nurses from two integrated acute/community NHS Trusts in Wales. A response rate of 55% was achieved. Respondents were asked to rate the importance of the selected attributes on a 5-point scale. They rated 'evidence-based practice', 'impact of care plan on patient's lifestyle', 'ease of care plan management' and 'speed of obtaining the equipment' highly, whereas 'affordability' was of less importance. However, regression analysis, which is part of the DCE technique, produced a somewhat different picture, with 'impact' being least and 'affordability' most statistically significant. The reasons for this apparent anomaly are discussed and the paper concludes that the DCE approach is capable of yielding important information, which is not produced by simple rating exercises. Such information is potentially of value in the context of modernisation and service configuration.

Final responsibility for treatment choice: the proper role of medical doctors?

Aims To analyse whether the traditional allocation of decision‐making responsibility is still justifiable. And, if not to analyse the strength of claims made by other health care professions and by patients. Background Traditionally doctors have been responsible for choices of treatment, both in terms of deciding and in terms of taking responsibility for the decisions. But modern health care work often takes place in teams involving health care professionals from different professions as well as the patient. In such teams it may not be obvious who should be responsible for treatment choice. Methods  Philosophical analysis of epistemic, ethical and organizational arguments, including analysis of the historical origins of these arguments. Results The epistemic, ethical and organizational arguments for maintaining a primary decision making role for doctors are not sound. Other health care professionals can, in some circumstances make stronger and more justified claims. The arguments against allocation decision making authority to patients are also invalid or unsound in many circumstances. Conclusion There are many situations in which final responsibility for treatment choice should rest with health care professionals who are not doctors and with patients.

Factors that contribute to quality of life outcomes prioritised by people with multiple sclerosis

The aim was to investigate factors associated with depression and social function, two outcomes identified as important by people with multiple sclerosis (MS) and to identify underlying dimensions of psycho-social well-being that may be useful as outcome measures. People with MS in eight randomly selected health authorities/boards in England and Scotland completed a postal questionnaire relating to preferences and needs for their health and social care, along with the Beck Depression Inventory and the SF-36. Responses to 10 of the original items were subjected to factor analysis. These and other explanatory variables were entered into multivariable regression models for the two outcomes. The factor analysis resulted in three dimensions representing different aspects of psycho-social well-being; one of these (representing autonomy) was associated with improvements in both outcomes, as was the SF-36 emotional role limitation score. Three other SF-36 dimensions and lack of contact with a health professional in the last year were related just to social function. The regression models emphasise the value of enabling autonomy and self-reliance amongst people with MS, as well as more general measures of emotional health. The present work identifies specific questions that could be used to measure pivotal aspects of an individual's psycho-social well-being. While these findings warrant replication for people with MS, they may have relevance to those with other long-term illnesses.
