The goal of this study was to examine the psychometric properties of the Aggression Questionnaire (AQ) in Spain. The AQ is a 29-item instrument designed to measure the different dimensions of the hostility/anger/aggression construct. It consists of 4 subscales that assess: (a) anger, (b) hostility, (c) verbal aggression, and (d) physical aggression. In Study 1, reliability, construct validity, and convergent validity were evaluated in a group of 384 male and female university students. Test-retest reliability was evaluated using a group of 154 male and female university students. The results of the factor analysis were similar to the scale structure claimed for this instrument. The subscales also showed internal consistency and stability over time. The AQ and its subscales were also compared with the scales and subscales of the Spielberger State-Trait Anger Expression Inventory (STAXI), the Cook-Medley Hostility Scale (Ho), the Buss-Durkee Hostility Inventory (BDHI), and the Jenkins Activity Survey-Form H (JASE-H). The results show that the AQ evaluates some aspects of anger, such as Anger-Trait and Anger-Out, rather than other elements, such as Anger-In or Anger-State. In Study 2, two new male groups were used to evaluate the criterion validity of the AQ: 57 prison inmates and 93 university students, finding that this instrument discriminated between the scores obtained by common offenders and university students.

For a sample of 305 6th, 7th, and 8th grade students, of whom 95% was from economically disadvantaged Hispanic families and for whom English was their second language, evidence was sought regarding the reliability and construct validity of scores on a Spanish version of an academic self-concept measure entitled Dimensions of Self-Concept (DOSC), comprising five subscales bearing the same names as those of the five hypothesized constructs that they were intended to operationalize: Level of Aspiration, Anxiety, Academic Interest and Satisfaction, Leadership and Initiative, and Identification versus Alienation. Reliability estimates varying between .72 and .80 were judged to be reasonably satisfactory. Results from oblique factor analysis lent empirical support for the hypothesized constructs of Anxiety, Leadership and Initiative, and Identification versus Alienation. Scores associated with the subscales of Level of Aspiration and Academic Interest and Satisfaction generated a factor interpreted as a fusion of the two constructs of Level of Aspiration and Academic Interest and Satisfaction.

Los años recientes han visto un interés creciente en la experiencia alucinatoria, incluidas investigaciones de su prevalencia fenomenológica y carácter tanto en poblaciones patológicas como normales (predispuestas). Investigamos la multidimensionalidad de las experiencias alucinatorias en 265 sujetos de la población normal que rellenaron una versión modificada de la Escala de Alucinaciones de Launay-Slade. Se realizó análisis de componentes principales sobre los datos. Se obtuvieron cuatro factores que saturaban en elementos que reflejaban (1) experiencias alucinatorias relacionadas con el sueño, (2) ensoñaciones diurnas vividas, (3) pensamientos intrusos o carácter real del pensamiento y (4) alucinaciones auditivas. Los resultados ofrecen nuevos datos de la multidimensionalidad de la disposición alucinatoria en la población normal. Se analizan direcciones para investigaciones futuras en la predisposición alucinatoria.

Se presenta la validación de la versión francesa de la Escala de Depresión Postnatal de Edimburgo (EPDS), realizada sobre una muestra de 87 mujeres en los 4 primeros meses de post- parto. El estudio de la sensibilidad, la especificidad y los valores predictivos frente a los Criterios para el estudio diagnóstico (RDC) proporcionan la puntuación de corte de 10,5 como la mejor (sensibilidad: 0,80; especificidad: 0,92). La EPDS tuvo también una buena validez de criterio como índice de la gravedad de la depresión postnatal, en comparación con la evaluación del psiquiatra. El análisis factorial muestra que la estructura interna de la EPDS se compone de dos subescalas que subrayan una descripción más precisa de la depresión postnatal. El estudio de la fiabilidad confirma la buena consistencia interna de la escala global (alfa de Cronbach: 0,76) y su buena fiabilidad test-retest a corto plazo (0,98).
