Impact de la violence politique sur la santé mentale des jeunes adolescents en Colombie. Analyse des facteurs de risque et de protection

El objetivo de esta investigación es examinar desde una perspectiva ecológica la salud mental de los adolescentes desplazados por la violencia política en Colombia. Se tomó como base el modelo ecológico integrado del impacto del trauma de Elbedour, ten Bensel y Bastien (1993), que estipula la influencia combinada de diferentes niveles de factores unidos a la experiencia traumática, factores individuales y factores proximales que vienen de la familia, y de los factores sociales de la red social familiar. El estudio se realizó con 98 jóvenes en edades entre los 9 a 16 años (M= 12.5 años, dt= 2.18), habitantes de las afueras de Barranquilla, de los cuales 48 son desplazados por la violencia (26 de sexo masculino, 22 de sexo femenino) y 50 son sedentarios pobres (26 de sexo masculino, 24 de sexo femenino). Los cuestionarios se escogieron en función de su utilización en contextos de pobreza y/o violencia (Macksoud, 1992; Macksoud & Aber, 1996; Macksoud, Aber, Dyregrov & Raundalen, 1990). Los resultados muestran que los adolescentes desplazados son más deprimidos y ansiosos que sus pares sedentarios. La ansiedad está unida al número total de eventos traumáticos, mientras que la depresión se explica más bien por la separación de los padres. Las competencias sociales y el ambiente social actúan como factores protectores. Entre los factores del ambiente social se observa el hecho de vivir en una familia extensa y de inscribirse en una red social que incluye a los amigos de la familia.  En su conjunto, la familia y la preservación de su unidad aparecen como elementos cruciales.

Familiar characteristics and received familiar support among Brazilian adolescents with and without pregnancy experience

The present paper aimed to investigate how adolescents with pregnancy experience evaluate received support from their families in comparison with an adolescent group without pregnancy experience. 452 low income adolescents, both sex, aged 14 to 19 years old answered to a questionnaire. The results revealed that more girls (64.2 %) than boys (35.8 %) declared pregnancy experience, ?2 (2, n = 2617) = 48.32, p < .001. Moreover, it was observed that the group with pregnancy experience, in comparison with other group, revealed more perception on the family relationships safety, t (408) = -3.0, p < .01; mutual respect among family members in their homes, t (392) = -2.3, p < .05; and received stronger general support from their family, t (397) = -1,3, p < .05. These results are discussed.

“The Ministry of Obligation warns”: it is necessary to protect the sexual offender adolescents

This text deals with a part of the research-action “Multifamiliar groups with sexual offender adolescents” and emphasizes the written production of the adolescents during the process. two texts were involved: the first one was a letter addressed to the parents and the second was an evaluation of the multifamiliar group. Seven adolescents between 14 and 17 years old wrote the texts. About the first text we discussed: the adolescent as responsible for the domestic work; the adolescent and his need to receive support and protection and the adolescent and the recognition of his growth phase. about the second text: the feelings of the adolescent regarding sexual abuse; the relation with the institution that carries out the intervention; the symbols that identify his ambivalence. We comment about the sexual abuse practiced by these adolescents as from two main points: the adolescence seen as a development phase and the role played by the family in the conduction of this phase.

Assessment of construct validity and reliability of the inventory of masculinity and femininity in adolescents and young adults Colombian

This study evaluated the construct validity and reliability of Femininity and Masculinity Inventory-Imafe (Lara, 1993), and calculated standardized punctuations for Colombian teenagers and young adults. Participants were 1527 male and female, between 15 and 42. The general and scale reliability was evaluated through Alfa and Guttmann coefficients, and the factor analysis was used to estimate the construct validity. Standardized punctuations were obtained for gender, since there were statistically significant differences for sex in the six scales of the instrument. The inventory presented reliability values that oscillated between .76 and .88, and the factorial analysis showed three factors coherent with the factors found in its original validation. Correlacional inter-scales analysis and sex-differences were theoretically consistent.

Visual processing of concentric sine-wave gratings in adolescents and adults

The aim of this study was to compare the contrast visual processing of concentric sinusoidal gratings stimuli between adolescents and adults. The study included 20 volunteers divided into two groups: 10 adolescents aged 13-19 years (M=16.5, SD=1.65) and 10 adults aged 20-26 years (M=21.8, SD=2.04). In order to measure the contrast sensitivity at spatial frequencies of 0.6, 2.5, 5 and 20 degrees of visual angle (cpd), it was used the psychophysical method of two alternative forced choice (2AFC). A One Way ANOVA performance showed a significant difference in the comparison between groups: F [(4, 237)=3.74, p<.05]. The post-hoc Tukey HSD showed a significant difference between the frequencies of 0.6 (p <.05) and 20 cpd (p<.05). Thus, the results showed that the visual perception behaves differently with regard to the sensory mechanisms that render the contrast towards adolescents and adults. These results are useful to better characterize and comprehend human vision development.

Relationship between siblings and psychological adjustment in adolescents:

This study evaluated the effect of parent-child relationship quality (acceptance and differential treatment) over dimensions of the quality of sibling relationships (warmth and conflict) and psychological adjustment in 69 adolescent sibling dyads. The effects of parent-child relationships were evaluated both at the individual and dyadic levels. In older siblings, the father-child relationship had a significant effect on both their perception of warmth in the sibling relationship and psychological adjustment. In younger siblings, there was a significant dyadic effect of the older sibling’s perceived acceptance by mother on their perception of warmth in the sibling relationship. Results are analyzed based on the literature and questions for future research are proposed.

Pregnancy in adolescents as a problem to 14 – 19 year olds in Nocaima (Cundinamarca)

Adolescent pregnancy is a current problem which raises concern due to its individual, familiar and collective consequences. Fifteen million adolescents give birth each year in the world. Abortion is the preferred option used in unwanted pregnancies. Adolescent pregnancy is frequent in Nocaima, Cundinamarca and is a community concern in this small town initiating its process of becoming a healthy municipality. As such, the community has highlighted this problem to be studied and submitted to intervention to promote a free and responsible sexuality decreasing unwanted adolescent pregnancies. Objective: To find data on contraception, pregnancy and related factors in selected adolescents therefore, improving current incomplete information. Methods: Descriptive observational study with survey application on 226 female 14 to 19 year old students from three high school facilities in Nocaima including 8th to 11th graders. Results: 88.9% of the participants were between 14 and 17 years of age. 66.8% of the adolescents claim to use correctly contraceptive methods and 28.8% have had sexual intercourse with an average initiation at age 15. 11.1% have been pregnant once in their lives and of these 57.1 % ended in induced abortion and 66.8% were school dropouts. Conclusions: After having implemented an educational campaign on healthy sex and reproductive behaviors we view adolescent pregnancy as a public health problem which is preventable and related to the deficit of social and family support as well as weakness in individual decision making.
