Creation and validation of a scale of sexuality for adolescents: Scale of Myths about Sexuality.

ABSTRACT

INTRODUCTION: In recent decades western countries have become more open about sexuality and sexual relations, and adolescents get information about these issues mainly through the internet, TV and social networks. Often such information is incomplete, wrong or even contradicts itself. What favors them to develop myths, false beliefs and/or negative attitudes about sexuality, love, equality in relationships, or Sexually Transmitted Infections. At the same time, the presence of myths favors double standards, sexism, and a negative attitude toward toward personal, partner and/or social sexuality. OBJECTIVES: To create a scale for evaluating the permanence of myths about sexuality in adolescents, and to analyze the structural reliability and validity of this scale. METHOD: The sample was formed by a pilot group (n=216) and a final group (n=661), both with adolescents from high schools in the province of Malaga, obtained by non-probability cluster sampling. The first 69 initial items were given to the pilot sample to determine the final questions making up the "Escala de Mitos sobre la Sexualidad". RESULT: All final items have an item-total correlation over 0.29. A final questionnaire was obtained of 27 items, grouped into 6 components. The Cronbach's alpha coefficient indicated a high internal consistency of the test (0.881). Moreover, it confirms a significant difference between the sexes and between grades (cohorts). CONCLUSION: The Scale has appropriate parameters for use in sex education and research. The use of this scale would help to discover adherence to the myths of adolescents, in order to eliminate them and build a solid, free and personal concept of sexuality.
