: The refinement of microelectronics has resulted in the exponential growth in the number and diversity of implanted biotechnical devices. As the number of people with implants increases it becomes imperative that healthcare professionals understand what it means to have a device implanted and the process of adjustment to that device. The IDAS was developed to measure how well a person is adjusting to life with an implanted device. A pool of items was generated and reviewed first by a panel of expert clinicians and then, after refinement by a joint panel of clinicians and nurse researchers familiar with psychometric measurement. Content validity indices were calculated after each panel review and items added, revised or deleted as appropriate. The tool was then administered to 10 patients with implanted cardiac devices who were debriefed to provide information about items that might be problematic. To assess reliability and validity, a convenience sample of 44 persons (30 males, 14 females) with implanted devices (21 pacemakers, 23 cardioverter/defibrillators) completed the revised IDAS. Cronbach alpha for the 28 item scale was .88. Four items with low item to total correlation were deleted and the revised scale alpha was .90. There was no significant difference between pacemaker and ICD patients on total scale scores. Correlation between a level of perceived adjustment visual analogue scale and the revised 23-item scale was .65, demonstrating construct validity. No significant differences in responses were found based on sex, age, or type of device. Two-week test-retest reliability for the 23 item IDAS was .90. In conclusion, this tool demonstrated strong reliability and validity in this sample. The IDAS may be useful for clinicians who wish to evaluate how well a person is adapting to her/his device. This may lead to more timely and appropriate interventions that can improve outcomes. AN: MN030285
