Ansiedad, autoestima e imagen corporal en niñas con diagnóstico de pubertad precoz / Anxiety, Self-esteem and Body Image in Girls with Precocious Puberty

resumen Actualmente se está produciendo una disminución de la edad de inicio de los cambios puberales, particularmente en las niñas, lo cual puede incidir en variables como ansiedad, autoestima e imagen corporal. El objetivo es establecer una comparación de estas variables en 2 grupos: uno de 15 niñas diagnosticadas de pubertad precoz y otro grupo de 16 niñas sin ese diagnóstico. Se realizó un diseño descriptivo no experimental, y para la medición de variables se utilizaron el State-Trait Anxiety Inventory for Children (STAIC) y el Self Description Questionnaire (SDQ). Se encontraron diferencias significativas entre ambos grupos en los niveles de ansiedad y de imagen corporal, pero no en los de autoestima. A través de los hallazgos obtenidos, se evidencia que las niñas que inician los cambios puberales de manera precoz sufren altos niveles de ansiedad y tienen una imagen corporal de sí mismas más negativa que las niñas que inician los cambios puberales en el momento normativo.

abstract Currently, the age of onset for pubertal changes is decreasing, especially in girls, which may have an impact on psychosocial factors such as anxiety, self-esteem and body image. The aim of the present study is to compare these variables in two groups: a group of 15 girls with precocious puberty and a group of 16 girls of the same age without precocious puberty. A non-experimental descriptive design was used and the State-Trait Anxiety Inventory for Children (STAIC) and Self-Description Questionnaire (SDQ) were used to measure variables. Significant differences were found in Anxiety and Body Image levels between groups, but there were no differences in Self-Esteem levels. In conclusion, the findings show girls with early onset pubertal changes present high anxiety levels and negative body image compared to girls who start pubertal changes at the normal time.

Development and validation of the theory of planned behavior questionnaire in physical activity.

The Theory of Planned Behavior (TPB) is one of the main theoretical models in the study of the different variables, which influence in the practise of physical activity. The aim in this study was to develop a questionnaire based on TPB in physical activity context providing evidence for the validity of the obtained measures. The instrumental project included three independent studies. The first study entailed the construction and qualitative assessment of the items. In the second study, the analysis of factorial structure was performed by means of exploratory measures, and it showed that the reliability of measures was adequate. The third study provided evidence on the dimensionality of the scale. The confirmatory factorial analysis guaranteed the stability of factorial structure proposed by the TPB and provided evidence for the internal validity of the inventory. Moreover, this study provided evidence of its external validity.

La Teoría de la Conducta Planeada (TCP) es uno de los modelos teóricos más empleados para conocer las diferentes variables que influyen en la realización de ejercicio físico. El objetivo en este trabajo fue elaborar un cuestionario basado en la TCP en el contexto del ejercicio físico y aportar evidencias sobre la validez de sus mediciones. El trabajo instrumental incluyó tres estudios independientes. El primer estudio consistió en la elaboración y evaluación cualitativa de los ítems. En el segundo estudio se analizó la estructura factorial mediante procedimientos exploratorios y se mostró que la fiabilidad de las mediciones era adecuada. El tercer estudio aportó evidencias sobre la dimensionalidad del inventario. El análisis factorial confirmatorio avaló la estabilidad de la estructura factorial propuesta por la TCP, así como aportó evidencias de validez interna del instrumento. También se aportan evidencias de su validez externa (AU)
