The Addenbrooke’s Cognitive Examination III is one of the most widely used tests to assess cognitive impairment. Although previous studies have shown adequate levels of diagnostic utility to detect severe impairment, it has not shown sensitivity to detect mild decline. The aim of this study was to evaluate the psychometric properties of Addenbrooke’s Cognitive Examination III in a large sample of elderly people through Item Response Theory, due to the lack of studies using this approach. A cross-sectional study was conducted with 1164 people from the age of 60 upwards, of which 63 had a prior diagnosis of Alzheimer dementia. The results showed that, globally, the Addenbrooke’s Cognitive Examination III possesses adequate psychometrics properties. Furthermore, the information function test shows that the subscales have different sensitivity to different levels of impairment. These results can contribute to determining patterns of cognitive deterioration for the adequate detection of different levels of dementia. An optimized version is suggested which may be an economic alternative in the applied field.

Se presenta un estudio cualitativo que tiene por objetivo describir las posiciones discursivas de estudiantes, docentes y familias respecto de la ciudadanía. Se realizaron 16 grupos de conversación a 107 participantes de centros educativos de dos ciudades chilenas. Tras un análisis estructural, los hallazgos dan cuenta de una estructura discursiva compuesta por diez posiciones discursivas. Encontramos dos grandes agrupaciones, la hegemónica (ciudadanía escolarizada, patriótica, burguesa, tutelada, infantilizadora, des-politizante y sexista) y la contra-hegemónica (contra-ciudadanía, cuerpo-parlante y protagónica). Estas posiciones se organizan en una estructura relacional que dispone y propone formas de comprender las distintas prácticas ciudadanas. Se concluye que el concepto hegemónico de ciudadanía regula las relaciones sociales para la formación de futuros ciudadanos y ciudadanas que logren convivir, integrar y reproducir una sociedad desigual. Asimismo, los espacios de enunciación de las disidencias o resistencias entregan pistas sobre las posibles grietas del modelo de ciudadanía que se impone en las escuelas.

The aims of this research were to estimate the percentage of body weight dissatisfaction in males and females Chilean adults, assessing its relationship with different sociodemographic, behavioral and psychological variables, and analyzing whether the presence of body weight dissatisfaction acts as a risk factor for some disordered eating behaviors. The 654 participants (436 women, 218 men; age range 18-64 years, mean body mass index [BMI] 25.49 kg/m 2 ) were evaluated with a battery of self-administered questionnaires. The percentage of body weight dissatisfaction in the whole sample was 45.9% and significantly higher in women than men. Significant differences were observed in the clinical scales that evaluated disordered eating in function of the BMI of the participants; in those scales females also showed higher scores than males. Comparing participants with and without body weight dissatisfaction, the first one showed more unhealthy eating behaviors. The results of this study show how body weight dissatisfaction can interact and influence healthy habits, such as a daily eating behaviors and physical exercise.
