Testing for Publication Bias in Political Science

If the publication decisions of journals are a function of thestatistical significance of research findings, the publishedliterature may suffer from "publication bias." This paper describesa method for detecting publication bias. We point out that toachieve statistical significance, the effect size must be largerin small samples. If publications tend to be biased againststatistically insignificant results, we should observe thatthe effect size diminishes as sample sizes increase. This propositionis tested and confirmed using the experimental literature onvoter mobilization.     

Validation of an Abbreviated Version of the Structured Interview of Reported Symptoms in Outpatient Psychiatric and Community Settings

This study examined the effectiveness of an abbreviated version of the Structured Interview of Reported Symptoms (SIRS-A) in identifying malingered mental illness. The SIRS-A is comprised of 69 items drawn from the SIRS (R. Rogers et al. 1992, SIRS: Structured Interview of Reported Symptoms: Professional Manual. Odessa, FL: Psychological Assessment Resources, Inc.), substantially reducing the administration time. A simulation design was used with three samples; 87 psychiatric outpatients who responded honestly were compared to 29 community-dwelling adults and 24 psychiatric patients instructed to malinger psychopathology. The SIRS-A generated sensitivity comparable to or exceeding that of the SIRS normative data, but specificity was poorer; many genuinely impaired patients were misclassified as malingering. Although these findings suggest the SIRS-A may be an effective means to assess malingering in psychiatric populations, further research assessing the reasons for the elevated false positive rates is necessary.     

Where do NGOs fit in?

The contribution of NGOs to the health sector has changed over recent years. Their profile and sector size have increased, and their activities are often different from those previously carried out. In some quarters NGOs are viewed as the best means of developing the health sector: regarded, among other things, as being more efficient and accountable than many developing-country governments. This article explores these developments and examines in particular one aspect that has been relatively ignored: the relationship between governments and the NGO sector within the health field. It concludes by looking at practical steps that can be taken to improve such relationships.
