The study aims to analyse the motivation and attitude of premarital medical examinees. Ninety-two premarital medical examines, which include 46 self-paid persons and 46 government paid (subsidized by the Department of Health) visited the Family Clinic. They were studied from Oct. 27, 1988 to Nov. 8, 1989. Among 48 male and 44 female examinees, the sex ratio (male:female) was 1.09:1. The predominant age distribution was 26-30 y/o (58.2%); and the predominant level of education was college (54.4%). Questionnaires were sent to these premarital medical examinees. We received 70 questionnaires-47.1% from self-paid, and 52.9% from government paid. The recovery rate was 76.1%. The results of analysis were: 1) Concerning the motivation of examination, 35.1% of self-paid were introduced by relatives or friends; while 50% of government paid were introduced by newspapers; 41.2% of the total response were afraid of genetic disease. 2) Concerning the opinion of the examination fee, there were no significant differences between those of self-paid and government paid.
