Effectiveness of a Genetics Self-Instructional Module for Nurses Involved in Egg Donor Screening

: To evaluate the effectiveness of a self-instructional module in increasing nurses' knowledge of genetics. : Pretest/posttest study design. Participants completed a pretest questionnaire used to measure baseline knowledge of basic human genetic concepts and risk assessment and collect descriptive data. Participants then reviewed a self-instructional module and completed a posttest questionnaire. : Study materials were mailed to 262 registered nurses involved in screening egg donors at 177 reproductive health centers in the United States from July to September 2000. : Sixty-five registered nurses working at reproductive health centers. One hundred of 262 eligible nurses completed the pretest (38% return rate) and 65 of these 100 nurses also completed the posttest (65% retention rate). : A 22-page self-instructional booklet on genetic risk assessment. : Pretest and posttest responses. : There was a significant increase of 20.8% in participants' mean knowledge score on the posttest (M= 89.0%, SD= 8%, range = 67%-100%) as compared with the pretest (M= 69.0%, SD= 12%, range = 42%-92%), based on paired t-test analysis (t= 11.74, SE= 0.426, p
