Surveys measuring confidence in CPR and intent to conduct CPR were administered after each skills test as part of the Selleck Fulvestrant post-test procedure. At one
year after initial CPR training and receipt of refreshers, subjects were contacted by their instructors to return to the original training site for the re-test, which had the same content as the post-test. Participants received $15 for completing the re-test. Adult CPR skill sheet (observation of performance) Inhibitors,research,lifescience,medical CPR skills were assessed by the instructor based upon a skill sheet for adult CPR as specified by the American Red Cross. This consisted of 39 observational items measuring CPR-related skills across two cycles of CPR performance. The total correct out of 39 possible was the score used in the statistical analyses. This method of testing, when scored by persons with expertise in CPR, has been shown to be a reliable method of measuring CPR Inhibitors,research,lifescience,medical skills . CPR confidence assessment This scale was computed from nine fixed response items answered by the participants, e.g., “how confident would you be about performing CPR if the victim still showed signs of life?” Each item was rated using the
following responses: “not at all confident” (=0), “slightly confident” (=1), “moderately confident” (=2), mostly Inhibitors,research,lifescience,medical confident (=3), and “totally confident” (=4). The respondent’s scores were averaged across the nine items to produce a continuous confidence score Inhibitors,research,lifescience,medical ranging from “0” (lowest confidence) to “4” (highest confidence), with internal consistency reliability (alpha) = 0.93. Behavioral intent to perform CPR The behavioral intent scale was based on a reduced set of 10 items from an original set of 21 Likert-type items, e.g., “how would you feel about responding to an emergency if the victim was a complete stranger?” Each item was rated using the following responses: “definitely not” (=0), “probably not” (=1), “not sure” (=2), “probably yes” (=3),
and “definitely yes” (=4). Inhibitors,research,lifescience,medical Psychometric examination reduced these 21 items to 10 items, whose responses were averaged to Mannose-binding protein-associated serine protease produce a continuous behavioral intent score ranging from “0” (lowest behavioral intent) to “4” (highest behavioral intent), with internal consistency reliability (alpha) =0.89. Satisfaction with the refreshers This consisted of 9 Likert-type survey questions completed at re-test, e.g., “the refresher I received was helpful for refreshing my CPR skills; this CPR refresher made me feel more confident about acting in the case of an emergency”. Exposure to the refreshers Measures of actual exposure to the refreshers were created by coding “1” for individuals who had at least one indication of interaction with the refresher (at least one e-mail opened, one text message response, or one website visit). These were determined by electronic tracking of subject behavior.
