Adolescencia, relaciones románticas y actividad sexual: una revisión
(LA Referencia, 2002) Elvia Vargas Trujillo; Fernando Barrera
Se presenta una revisión de algunas de las investigaciones\nmás recientes sobre la adolescencia y los factores asociados\na las relaciones románticas y la actividad sexual durante la\nadolescencia. Se parte de la premisa de que el análisis de la\niniciación romántica y sexual durante la adolescencia\nrequiere de modelos de causalidad múltiple que permitan\ndar cuenta, conjuntamente, de los factores que se\nencuentran en los contextos individual, familiar y social\nasociados con estos dos procesos. Se destaca el papel de los\npadres en el desarrollo de hijos adolescentes autónomos,\ncapaces de manejar la influencia negativa del grupo de\npares. Se hacen algunas recomendaciones a los responsables\nde diseñar programas de prevención y a los interesados en\nel estudio de la adolescencia y en el desarrollo de la disciplina.
ES LA AUTOESTIMA UNA VARIABLE RELEVANTE PARA LOS PROGRAMAS DE PREVENCIÓN DEL INICIO TEMPRANO DE ACTIVIDAD SEXUAL
(2005) Elvia Vargas Trujillo; Fernando Barrera
Se presentan los resultados de tres estudios transversales, no experimentales, correlacionales que se realizaron para responder a las preguntas que proponen Vargas Trujillo, Gambara y Botella (sometido a publicación) al final del estudio meta-analítico que realizaron para examinar la relación de la autoestima con el inicio de actividad sexual en la adolescencia. Los hallazgos indican que en Colombia, al menos en el grupo de adolescentes vinculados al sistema educativo en Bogotá, la autoestima no es una variable relevante para los programas de prevención del inicio temprano de actividad sexual. Los análisis sugieren que la autoeficacia y el contexto normativo en el que se desarrollan los adolescentes sí establecen diferencias significativas en el estatus sexual y en la edad a la que se tienen relaciones sexuales por primera vez.
La intención de los jóvenes de tener relaciones sexuales en la adolescencia: el papel de la televisión, la relación con los padres y las cogniciones
(2006) Elvia Vargas Trujillo; Fernando Barrera; María Consuelo Burgos; Berta Cecilia Daza
This study assessed the influence of television, parent-child relationship and adolescents’ cognitions over the intentions to engage in sexual activity during adolescence. Sample consisted of 231 high-school students (116 women and 115 men), between 12 and 18 years old, from low, middle and high socioeconomic status. A self-report questionnaire was used to gather information on the study’s variables. Correlation and regression analysis show that intentions are determined by personal attitudes and subjective norm, thus supporting the Theory of Planned Behavior. Sexual self-efficacy was not a significant predictor of the intentions to engage in sexual activity during adolescence. Some variables related to TV were found to be strong determinants of personal attitudes toward sexual activity during adolescence. The findings are discussed with implications for actions by parents, educators and those responsible of TV policies.
RELACIÓN DE LAS ACTITUDES PERSONALES Y DE LA NORMA SOCIAL CON LA ACTIVIDAD SEXUAL DE LOS ADOLESCENTES
(Universidad de Los Andes, 2004) Fernando Barrera; Estefanía Sarmiento; Vargas Trujillo Elvia
Using a sample of 326 high-school students (178 males, 144 females, 4 participants who did not indicate their sex) between 13 and 18 years old, from lower, middle and upper socio-economic levels, the relationship between personal attitude and the perceived social norm (perception of friends' attitude and of peer norm) was examined with several indicators of the sexual activity of participants. A self-report questionnaire was used in order to get information about the variables of the study. The analysis of information showed that only one 31 percent of the young participants had had penetrative sexual relationships. Correlation and regression analyses support the statements of Reasoned Action Theory on the importance of personal attitude and the youth's perception of the social norm in explaining sexual activity during adolescence. The study's predictive variables explain between a 10 percent and a 60 percent variability of each one of the sexual activity indicators. It was statistically verified that the influence of perception of sexual attitudes of friends on penetrative sexual activity takes place through the personal sexual attitude. These results confirm the role of cognition in healthy behaviour and point to the need to bear it in mind in programs of sexual and reproductive health promotion campaigns.
RELACIONES FAMILIARES Y COGNICIONES ROMÁNTICAS EN LA ADOLESCENCIA: EL PAPEL MEDIADOR DE LA AUTOEFICACIA ROMÁNTICA
(Universidad de Los Andes, 2005) Fernando Barrera; Elvia Vargas
A conceptual proposal was examined concerning the influence of family relations on romantic autonomy and connectedness expectations in adolescents. Self-efficacy for romantic relations was construed as a mediating variable between perceived family relations and adolescents’ romantic expectations. Self-report measures of family and romantic cognitions were obtained form 326 female and male adolescents. Results showed that family relationships had direct effects on both selfefficacy and romantic expectations. A mediating significant effect of self-efficacy was established. These results are congruent with the social cognitive theory as well as the socialization theory.
