title: Evaluation of satisfaction and use of electronic intervention for behavior change.
abstract: This report describes use and satisfaction of a tailored intervention delivered via Web site and handheld computer. All participants used both delivery methods. Healthy women (N = 74) aged 40 to 60 years participated in this mixed-method descriptive study. Satisfaction was measured via Computer Satisfaction Questionnaire and open-ended comments. Data on use of the handheld computer were embedded into program and captured real time. Unique Internet provider addresses tracked Web site use from March 2007 through August 2008. Results indicate 80% of participants were very to extremely satisfied. There was no significant relationship between use and satisfaction. Knowledge but not self-efficacy scores differed over time. Usage was not related to knowledge scores. Handheld computer was used most frequently during the first week, with use decreasing over 7 weeks. Personal assessment of calcium intake and feedback sections were used most frequently. Handheld computer was used by 71% of participants for 4 weeks, 55% for 6 weeks, and 29% for the full 8 weeks. Participants commented on intervention content and positive and negative aspects of the devices and keyboard. This study presented an opportunity to examine data related to actual use. This dimension of intervention fidelity is more readily available in eHealth applications than with printed information.
