Effects of a Sexual Risk‐Reduction Intervention for Teenagers: A Cluster‐Randomized Control Trial, 2022

For the initial sample, 2047 teenagers aged 14-19 years from 14 schools in 11 Colombian cities participated; eight schools were randomly assigned to the experimental condition and six to the control group. The participants completed self-report assessments that evaluated several variables theoretically associated with protective sexual behaviors. In the short term, the experimental group showed increased knowledge about HIV and other STIs, sexual assertiveness, self-efficacy, greater behavioral intention toward condom use, and more favorable attitudes toward HIV and condom use than the control group. After 6 months, most psychological and health variables also showed a significant positive change. In conclusion, the COMPAS program is the first school-based sexuality education program that has been shown to be effective in reducing mediating and behavioral variables associated with sexual risk reduction in Colombia.

Seventy-three women (36.9 ± 13.6 years) who had been victims of domestic violence participated. The analysis was based on their coping strategies, early maladaptive schemes, and their decisions in response to vignettes describing the following domestic violence situations: humiliation to women’s maternal identity with children as witnesses and body shaming. We used Student’s t and Mann–Whitney tests to compare the results between groups. The participants presented some coping strategies (social support seeking, wishful thinking, and professional support seeking) and several early maladaptive schemes (emotional deprivation, defectiveness/shame, social isolation/alienation, failure to achieve, attachment, and subjugation) associated with their reactions facing a situation of humiliation with children as witnesses. When the humiliation was against the body image, their reactions were associated with some coping strategies (wishful thinking, professional support seeking, autonomy, negative auto-focus coping, and positive reappraisal) and one maladaptive scheme (defectiveness/shame). Women who reacted avoidantly showed higher social and professional support seeking but experienced higher indicators of discomfort and deterioration of self-esteem than those who opted for assertive decisions. The presence of children as witnesses seems to be a factor of stress in the configuration of coping strategies and maladaptive schemes in female victims of domestic violence. The evolution of early maladaptive schemes and coping strategies requires observation to avoid the risk of isolation and permanence in victimizing relationships.
Colombian Adaptation of the HIV and Other Sexually Transmitted Infections Knowledge Scale (KSI) in an Adolescent Population

Knowledge about HIV/AIDS and other STIs has been identified as a factor in promoting healthy sexual behavior. The HIV and Other Sexually Transmitted Infections Knowledge Scale (KSI) is an instrument created in Spain to assess sexual health knowledge in adolescents. In view of the lack of scales that measure this construct in Colombia, this study aims to culturally adapt and validate the KSI for the Colombian adolescent population. The sample was comprised of 866 adolescent school children (458 females and 408 males) aged between 14 and 19 years (M ¼ 15.97, SD ¼ 1.36) from 12 schools in the cities of Bogotá (n ¼ 467) and Barranquilla (n ¼ 400). Results showed good item psychometric properties and adequate discrimination and difficulty indices. Factorial analysis confirmed a five-dimensional factor structure. The indicators of validity showed significant correlations with constructs related on theoretical grounds. In sum, the study presents a valid and reliable scale for evaluating knowledge about HIV and other STIs in Colombian adolescent population.

A fundamental criterion for the designing and adaptation of these programs is the age of their target populations because limited education and language are the most relevant factors that limit the efficacy of these programs. The contribution of this paper consists of assessing both the readability of the written materials that accompany the contents of a Spanish-written school-based sexual health promotion program used in Colombia, as well as the words co-occurrence network structure of its contents. The readability of the evaluated program corresponded to its intended target population aged between 14 and 19, with the schooling of 9-13 years of education. The resulting words co-occurrence network structure of the COMPAS program also mirrored its theoretical content. These results all together are deemed as empirical evidence of the adequacy of the program.

This descriptive and cross-sectional study’s purpose was to examine sexual behavior and its precursors using the theory of planned behavior (TPB) and considering gender-based differences. Another objective was to study the mediating effect of intention in the relationship between behavior precursors and condom use based on the TPB.
