Developing a Multi-Dimensional Early Elementary Mathematics Screener and Diagnostic Tool: The Primary Mathematics Assessment.

There is a critical need to identify primary level students experiencing difficulties in mathematics to provide immediate and targeted instruction that remediates their deficits. However, most early math screening instruments focus only on the concept of number, resulting in inadequate and incomplete information for teachers to design intervention efforts. We propose a mathematics assessment that screens and provides diagnostic information in six domains that are important to building a strong foundation in mathematics. This article describes the conceptual framework and psychometric qualities of a web-based assessment tool, the Primary Math Assessment (PMA). The PMA includes a screener to identify students at risk for poor math outcomes and a diagnostic tool to provide a more in-depth profile of children's specific strengths and weaknesses in mathematics. The PMA allows teachers and school personnel to make better instructional decisions by providing more targeted analyses.

Perceived Health Risks of Snus and Medicinal Nicotine Products.

INTRODUCTION: Perceived health risk (PHR) of a tobacco product may influence both uptake and continued use. In this study, we examined PHRs of snus and medicinal nicotine using the PHR scale and the relationship of PHR responses to use of these products in smokers seeking an alternative to smoking. METHODS: Smokers were randomly assigned to snus or to medicinal nicotine for a period of 12 weeks and asked to only use the assigned product. The PHR scale involves rating the extent of perceived risk of a product for different diseases and was given at baseline and weeks 4 and 12 during treatment. Relationships between PHR scale scores and study attrition, compliance with only using the product, and continued use of the product after treatment were determined. RESULTS: Response to the PHR scale showed no significant differences between the snus and medicinal nicotine for perceived risks for lung cancer, emphysema, and bronchitis. However, significant differences were observed for other cancers, heart disease, stroke and risk for addiction, particularly after product use, with higher scores among those assigned to snus. Scores on the PHR scale were not related to any of the trial outcome variables. CONCLUSIONS: Among smokers seeking an alternative to smoking in a clinic setting, PHR of a product changes after product use but may not be related to product use patterns. IMPLICATIONS: PHRs of snus or medicinal nicotine in smokers assigned to these products become more accurate after product use. PHR does not appear to be associated with patterns of product use; rather satisfaction with a product is a better indicator as to whether a smoker is compliant with only using the product or continues to use the product.

Subjective responses to oral tobacco products: scale validation.

INTRODUCTION: Several noncombusted oral tobacco products have been introduced that are primarily marketed to cigarette smokers. An important component of evaluating these products involves assessment of subjective responses to the product. To date, few studies have been undertaken to examine the validity of subjective response questionnaires for oral tobacco products. The goal of this study is to examine the extent subjective responses to a product are related to product preference and extent of product use. METHODS: Data from a study examining oral tobacco product preference were used. Smokers were asked to sample a variety of oral tobacco products that differed in formulation (snus versus dissolvables) and dose of nicotine. At the end of the sampling period, subjects were asked to choose the product that they would use to completely substitute for cigarettes for the next 2 weeks. During the sampling period, subjects completed a Product Evaluation Scale (PES) that describes subjective responses to the product. During the treatment phase, they kept record of amount of product use. RESULTS: Subjective responses to the product on the PES were related to product choice and to some extent, the amount of product use. Product choice was associated with different characteristics of the product and smoker needs. CONCLUSION: The PES may be a useful tool for the evaluation or oral tobacco products.

Smokeless tobacco use in military personnel.

Military personnel are more than twice as likely as civilians to use smokeless tobacco (ST), and recent studies indicate that military prevalence rates are rising. However, few studies have examined factors related to ST use in the military. The present study evaluated the characteristics of ST use in 785 active duty military personnel. The results indicated that the average age of initiation was 17.7 years, participants had used ST for 12.3 years, and they used approximately four tins or pouches of tobacco per week. Army personnel were more likely than Air Force personnel to be older, to have used ST longer, and to be heavier users. Officers had used ST longer than enlisted personnel and were more likely to have had a recent quit attempt. Enlisted personnel were more than three times as likely to report concurrent cigarette smoking. These results indicate that there are significant differences in ST use patterns in military personnel, and cessation programs should be tailored to meet these differences.
