A condom skill scale: assessing condom skills among female drug users.

Use of latex condoms is a primary form of sexual risk reduction, and consequently many intervention programs have focused efforts on increasing condom use among high-risk populations. Use alone, however, will not fully protect the individual if condoms are not used correctly. The objective of this study was to describe the development and properties of a scale measuring demonstrated condom use skill using a sample of 261 drug-using women. Guttman's coefficient of reproducibility and Jackson's Plus Percentage Ratio (PPR) were used to determine the scalability of the Condom Skill Scale (CSS). Analysis of scale scores revealed high levels of condom skill among the population, although there was reduced performance for three items. Preliminary analysis suggests that the CSS is a potentially valid and reliable instrument, and may have application as a tool assessing condom skill level.
