Standard setting: comparison of two methods.

BACKGROUND: The outcome of assessments is determined by the standard-setting method used. There is a wide range of standard-setting methods and the two used most extensively in undergraduate medical education in the UK are the norm-reference and the criterion-reference methods. The aims of the study were to compare these two standard-setting methods for a multiple-choice question examination and to estimate the test-retest and inter-rater reliability of the modified Angoff method. METHODS: The norm-reference method of standard-setting (mean minus 1 SD) was applied to the 'raw' scores of 78 4th-year medical students on a multiple-choice examination (MCQ). Two panels of raters also set the standard using the modified Angoff method for the same multiple-choice question paper on two occasions (6 months apart). We compared the pass/fail rates derived from the norm reference and the Angoff methods and also assessed the test-retest and inter-rater reliability of the modified Angoff method. RESULTS: The pass rate with the norm-reference method was 85% (66/78) and that by the Angoff method was 100% (78 out of 78). The percentage agreement between Angoff method and norm-reference was 78% (95% CI 69% - 87%). The modified Angoff method had an inter-rater reliability of 0.81-0.82 and a test-retest reliability of 0.59-0.74. CONCLUSION: There were significant differences in the outcomes of these two standard-setting methods, as shown by the difference in the proportion of candidates that passed and failed the assessment. The modified Angoff method was found to have good inter-rater reliability and moderate test-retest reliability.

Interleukin-6 promoter polymorphism: risk and pathology of Alzheimer's disease.

Inflammatory and immune responses are involved in the pathogenesis of Alzheimer's disease (AD). Interleukin-6 (IL-6), an inflammatory cytokine, is thought to play a role in neurodegeneration of the central nervous system and has been associated with increased amyloid precursor protein expression in vitro and greater cognitive decline. Previously a C-174G polymorphism in the promoter of IL-6, which influences expression in vitro, has been found associated in some studies but not all. We investigated this polymorphism in a large independent UK sample of AD cases (n = 356) and controls (n 434) but found no association. We extended the study to genotype/phenotype correlations but found no correlation with age of onset (n = 338), brain amyloid load (n = 126) or Tau load (n = 101), brain microglial cell load (n = 65) or brain reactive astrocytes (n = 127). Our data do not support a pathogenic role in AD for the C-174G polymorphism in isolation.

Multiple contacts with diversion at the point of arrest.

A diversion at the point of arrest (DAPA) scheme was set up in five police stations in South Birmingham in 1992. In a study of all referrals made over a four-year period a sub group of multiple contact individuals was identified. During that time four hundred and ninety-two contacts were recorded in total, of which 130 were made by 58 individuals. The latter group was generally no different from the single contact group but did have a tendency to be younger. This research highlights the need for a re-evaluation of service provision and associated education of police officers and relevant mental health care professionals.

Insight, social knowledge and working memory in schizophrenia.

BACKGROUND: There is evidence that insight and social judgements are impaired in schizophrenia. The influence of these factors on the decision to treat compulsorily in schizophrenia is poorly understood. AIMS: To investigate the contribution of insight, social knowledge, and working memory to the determination to treat coercively in schizophrenia. METHOD: Insight rating scale, social knowledge questionnaire and working memory tests were administered to detained patients with schizophrenia. Results were compared with those of a control group of voluntary in-patients with schizophrenia. RESULTS: Detained patients scored worse on insight and social knowledge, yet there was no significant correlation between these scores. There was no significant difference in severity of psychopathology between the experimental and control groups. Results for working memory were inconclusive. CONCLUSION: Insight and social knowledge are significantly, but independently, associated with the determination to treat coercively in schizophrenia. This suggests that insight and social knowledge are distinct skills. The contribution of working memory remains unclear.
