ABSTRACT This study hypothesized that attitudes toward human sexuality would become more positive and knowledge would increase following a human sexuality training workshop. The experimental subjects, who were practicing professionals, were given the SKAT in the first hour of the workshop and again in the last hour of the workshop on the third day. There were 57 subjects: 16 in group 1; 16 in group 2; and 25 in group 3. The control group consisted of 8 subjects who were practicing professionals who did not attend the workshop, but who took the SKAT test and then repeated the exam three days later. The results of the study supported the research hypothesis in the areas of attitudes on heterosexual relations, sexual myths, and autoeroticism and sexual knowledge. The control group did not change significantly on their pre and posttest scores. The raw scores showed that there was approximately a 7.5 point difference in the mean scores of the experimental groups tested in urban areas and those subjects from rural areas. The urban scores were higher which indicated more liberal attitudes toward human sexuality and more cognitive knowledge. Sixteen of the subjects decreased on their posttest scores of the attitudinal sections of the SKAT but this did not affect the overall statistical significance of the study. Those experimental subjects who decreased were from a rural area and were public health nurses, females, married, and over thirty years old. Sexual knowledge increased in all the experimental subjects. The findings showed a wide range of differences between individuals' perceptions and their actual scores on the sexual knowledge section. Human sexuality is an area of considerable concern in today's contemporary culture. The increased openness about sexual behavior is resulting in the consumer seeking counsel and answers to their sexual problems from helping professionals. The professionals need to possess self-knowledge before they can help others. Health professionals have tended to exhibit a lack of adequate knowledge about sex education and counseling.1
