Previous research demonstrates a marked increase in the occurrence of depression during adolescence, particularly for females. Research has found that this phenomenon is associated with the development of beliefs about the self, world, and future (known as the cognitive triad), which constitutes a potential cognitive vulnerability to depression. Research has also demonstrated that family characteristics, such as cohesion, communication, conflict, social/recreational activity, negative life events, and maternal depression are all related to depression and the development of a negative cognitive style. The purpose of the current study was to build upon previous literature on negative life events, family and cognitive correlates of depression in youth, and analyze specific cognitive-interpersonal pathways to depression for girls transitioning from childhood to adolescence. 194 girls ranging in age from 8 to 14 participated in the study, along with their mothers. Participants completed self-report measures of family environment, beliefs about the self, world, and future, and negative life events. Mothers completed a self-report measure of psychopathology. Participants also completed a diagnostic interview, which served as the primary measure of depressive symptoms. As found in similar studies and consistent with Beck’s theory of depression, daughter’s reports of cognitive triad predicted the severity of her depressive symptom severity. Moreover, the cognitive triad was found to be the mediating variable in the model; family variables affected daughter’s beliefs, which then affected depressive symptom severity. Specifically, girls who endorsed higher family conflict and lower social/recreational activity reported a more negative cognitive triad and subsequently higher levels of depression. Additionally, negative life events significantly affected cognitive triad and indirectly affected depressive symptoms via cognitive triad. Also, the interaction of negative life events and cognitive triad significantly affected depression. Further results indicated that the self subscale of the cognitive triad is a particularly important factor in this model of depression. Contrary to what was expected, mother’s reports of depressive symptoms did not predict daughter’s cognitive triad or depressive symptoms. Implications of these results, limitations, and recommendations for future research are provided. / text

Recent research has suggested that the effects of sport on well-being are mediated by psychological characteristics such as physical self-concept, instrumentality and positive body images; in addition, sport was found to be related to these psychological benefits for high school girls. However, physical self-concept played a central role by mediating the sport -body image and sport instrumentality relationships. Positive body image and instrumentality, in turn, predicted greater psychological well-being. The purpose of this investigation was to replicate earlier studies, and to examine these relationships with non-sport physical activity. Sport and physical activity were expected to contribute to higher physical self-concept, which in turn, would contribute positively to instrumentality and body image. Further, instrumentality and body image would be positively related to psychological well-being. Participants were 355 9th (n = 170) and 10th (n = 193) graders and they completed measures of involvement in sport/physical activities, physical self-concept, instrumentality, body satisfaction, self-esteem, satisfaction with life, depression, and demographics. Structural equation modeling was utilized to analyze the data. Overall, for both sport and physical activity, the models fit the data well (sport model: NNFI=.95, CFI=.96, SRMR=.08, RMSEA=.09, physical activity model: NNFI=.96, CFI=.97, SRMR=.08, RMSEA=.09). Specifically, sport participation was positively related to physical self-concept (R2 = .47); physical self-concept related to body image (R2 = .30) and instrumentality (R2 = .23); Physical activity was positively related to physical self-concept (R2 = .61); physical self-concept related to body image (R2 = .30) and instrumentality (R2 = .26). For both models, positive body image and higher levels of instrumentality contributed to greater psychological well-being (R2 = 66). These results highlight the importance of developing physical competence for high school girls through sport participation and physical activity.

Nos dias de hoje, a obesidade se caracteriza como uma doença de causas múltiplas, sendo uma enfermidade grave e com alta incidência em países desenvolvidos e em desenvolvimento. Dessa maneira, é possível considerar que a obesidade pode ser analisada por vários aspectos multifatoriais como os genéticos, sociais e afetivos. Nesse sentido, esta dissertação aborda alguns aspectos afetivos presentes na problemática da obesidade e sobrepeso em adolescentes mulheres, procurando verificar possíveis falhas na relação afetiva mãe e filha, nos estágios precoces do desenvolvimento da menina. Este estudo está fundamentado em concepções teóricas de Winnicott (1983; 2000; 2005; 2006), Levisky (1995), Barbosa Silva (2005), Bruno (2011) e Cardoso (2008). Foi utilizada como procedimento metodológico a abordagem qualitativa da História Oral de Vida que privilegia as narrativas do sujeito como compreensão de suas vivências afetivas. Desse modo, foram feitas entrevistas gravadas com as adolescentes obesas ou com sobrepeso de 13 a 18 anos que fazem parte da triagem ou estão em tratamento nutricional na Clínica-Escola de Nutrição da Faculdade de Ciências Biológicas e da Saúde do Centro Universitário (Cesmac) em Maceió, Alagoas. Diante disso, as narrativas das adolescentes entrevistadas teceram sua história de vida, apresentando dados significativos como a relação com a mãe, o contexto familiar, o próprio ato de adolescer e o lidar com os conflitos existentes no dia a dia como aspectos importantes e como hipóteses possíveis de ocasionar o aparecimento da obesidade e do sobrepeso nessas adolescentes mulheres. Cada contexto estudado, revela singularidades da relação mãe e filha e se destaca como fundamental para o desenvolvimento e a construção do amadurecimento da menina na infância e, principalmente, na adolescência. / Nowadays, obesity is characterized as a disease of multiple causes, its a serious illness and with high incidence in developed and developing countries.

It was used as methodological procedure the qualitative approach of Oral Life History that privileges the narratives of the subject as knowledge their affective experiences. Thus, they have been recorded interviews with obese adolescents or overweight 13 to 18 years who are part of the screening or are in the nutritional treatment Clinic-School of Nutrition of Biological Sciences and Health College (Cesmac) in Maceió, Alagoas. In this way, the narratives of the interviewed adolescents wove their life story, they are presenting significant data such as the relationship with the mother, the family context, the own act of adolescent and the dealing with conflicts in daily life as important aspects and as possible hypotheses to bring on the onset of obesity and overweight in these adolescent women. Each studied context, reveals singularities mother and daughter relationship and it stands as fundamental to the development and the construction girls maturing in childhood, and mainly, in youth.
