Development, validation, and use of English and Spanish versions of the telemedicine satisfaction and usefulness questionnaire.

OBJECTIVES: To describe the development and validation of low literacy English and Spanish versions of the 26-item Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ), report telemedicine satisfaction and usefulness ratings of urban and rural participants in the Informatics for Diabetes Education and Telemedicine (IDEATel) project, and explore relationships between utilization and perceptions of satisfaction and usefulness. METHODS: Data sources included TSUQ, utilization data from IDEATel log files, and sociodemographic data from the annual IDEATel interview. Psychometric analyses were conducted to examine the reliability and validity of TSUQ. Data were analyzed using descriptive, correlational techniques. RESULTS: The principal components factor analysis extracted two factors (Video Visits, alpha=.96, and Use and Impact, alpha=.92) that explained 63.6% of the variance in TSUQ satisfaction scores. All satisfaction and usefulness items had mean scores of greater than 4 on a 5-point scale. Those from urban areas reported significantly higher ratings on both factors than rural participants as did those who did not know how to use a computer at baseline. Mean frequency of utilization of IDEATel components was highest for blood sugar testing followed by web site for reviewing results, blood pressure testing, video visits, and ADA educational Web pages. Associations between utilization and perceptions of satisfaction and usefulness varied among IDEATel components. CONCLUSION: Psychometric analyses support the construct validity and internal consistency reliability of TSUQ, which is available in both English and Spanish at a readability level of 8th grade. Both rural and urban participants reported high levels of satisfaction and found all IDEATel components useful. Further work is needed to examine the relationships between utilization and perceptions of satisfaction and usefulness and to explore the effects of location (urban versus rural) and ethnicity on satisfaction with telemedicine services.

Availability of antibiotics without prescription in New York City.

Misuse of antibiotics in the community has been associated with emergence of increasingly antibiotic-resistant bacterial strains. Although antibiotics in the United States are to be prescribed by a health care provider, the extent to which they are obtained by other means is not known. The purpose of this article is to describe a survey of the availability of nonprescription antibiotics in neighborhood independent businesses in several Manhattan, New York, neighborhoods. A survey was conducted of 101 stores in three neighborhoods--one primarily Hispanic; one primarily black, non-Hispanic; and one primarily white, non-Hispanic. Antibiotics were available in all stores in the Hispanic neighborhood (n = 34), but in none of the others (P < .001). If efforts to rationalize the use of antibiotics are to be successful, the beliefs and cultural norms of subpopulations must be considered, and interventions must be culturally relevant.
