Too Good to be False: An Essay in the Folklore of Social Science

In 1939, Carl Hovland and Robert R. Sears presented data that they believed linked fluctuations in the price of cotton to lynchings in the South, a linkage first suggested six years earlier by Arthur Raper. This correlation quickly became a popular illustration of frustration-aggression theory. A few years later, a statistical critique by Alexander Mintz cast the reality of the association into doubt, but a sample survey of members of the Society for the Psychological Study of Social Issues reveals that Howland and Sears's "finding" is still widely, if imprecisely, known and accepted. Their article continues to be cited in the social-psychological literature and in many introductory textbooks. The failure of Mintz's critique to catch up with the striking but flawed, original report illustrates a structured impediment to reliable knowledge in the social sciences.     

Learning about radon's risk

This article reports the results of an evaluation of the effectiveness of different types of information materials in communicating the risk from exposure to radon, a naturally occurring indoor air pollutant. The study involved a panel of 2300 homeowners who actually experienced risks from radon, and the information program used to explain these risks. The analysis considered information transfer and performance on specific tasks requiring information on the risk from radon to measure learning. The results suggest a systematic learning process, but indicate that the process can be influenced by how risk information is presented.

Brief Screening and Intervention for Alcohol and Drug Use in a College Student Health Clinic: Feasibility,Implementation, and Outcomes

Abstract

Objective: Evaluation of the Brief Alcohol Screen and Intervention in College Students (BASICS) in a university primary care setting. Participants/Methods: Undergraduates (N = 449) participated in BASICS and electronic surveys assessing frequency/quantity of alcohol and drug use, psychosocial and mental health outcomes, and demographic information. Data were collected at baseline and 6-month follow-up between August 2006 and August 2008. Results: Drinking and drug use decreased between baseline and 6 months. Participants reported an increase in protective factors and in readiness to change alcohol-related behaviors, and a decrease in alcohol-related consequences and in distress symptoms. Heavy episodic drinking at baseline significantly moderated the changes in number of drinks in a typical week and in a typical weekend, and number of drinks on the occasion drank most on a weekend. Conclusions: BASICS can be implemented in a primary health care setting and university students may reduce their alcohol and/or drug use.     

Developing a Low‐Cost Technique for Parallel Cross‐Cultural Instrument Development: The Question Appraisal System (QAS‐04)

Many approaches are used to prepare instruments for multicultural administration, depending on the scope, schedule and budget of the study. Sequential questionnaire development, the most common approach to developing cross‐cultural instruments, is also the most affordable. Designers formulate and pretest an instrument in the source language, then translate it into the target language(s) using culture‐specific tailoring. In contrast, parallel development incorporates target cultures throughout the design and pretesting process. The disadvantages to parallel development are that it is expensive, time‐consuming and subject to version control problems. Question Appraisal System (QAS) is a coding tool for pretesting instruments. The QAS is supported by an item taxonomy of the cognitive demands of a question and documents the features that may lead to response error. Results of the appraisal are used to revise question wording, response wording, questionnaire format and question ordering. This article describes research conducted to update the QAS to identify problems due to cross‐cultural and cross‐linguistic application of questions.
