Internet training courses for Nurse Aides (NA) in long term care facilities (LTCs) have been shown to be effective., Little is known, however, about Internet training effects on NAs in a non-research context, or about continued utilization of an available training program. In this research, a replication study was conducted with the Internet training program Caring Skills: Working with Mental Illness. Three LTCs provided the training to all NAs, each within a one-month interval scheduled during consecutive months. Supervisors were interviewed subsequently about their experiences organizing and supervising the training. Participants in all three LTCs showed positive pre-posttests effects with large effect sizes on situational knowledge and self-efficacy, and knowledge about mental illness. Users rated the program highly, and they indicated that it would improve quality of their resident care. Supervisors praised the training, and they said NAs were using recommended training behaviors. Although available to all staff, nursing and other staff made little use of the training in subsequent months. Training for NAs on the internet thus appears feasible, and it is perceived to be beneficial for resident care. Plans for continued utilization and dissemination of best practices to other staff, however, should be integrated when planning for staff training on the Internet.
