Test-Retest Reliability of the Spanish Version of the Diagnostic Interview Schedule for Children (DISC-IV)

The test-retest reliability of the Spanish Diagnostic Interview Schedule for Children (DISC-IV) is presented. This version was developed in Puerto Rico in consultation with an international bilingual committee, sponsored by NIMH. The sample (N = 146) consisted of children recruited from outpatient mental health clinics and a drug residential treatment facility. Two different pairs of nonclinicians administered the DISC twice to the parent and child respondents. Results indicated fair to moderate agreement for parent reports on most diagnoses. Relatively similar agreement levels were observed for last month and last year time frames. Surprisingly, the inclusion of impairment as a criterion for diagnosis did not substantially change the pattern of results for specific disorders. Parents were more reliable when reporting on diagnoses of younger (4–10) than older children. Children 11–17 years old were reliable informants on disruptive and substance abuse/dependence disorders, but unreliable for anxiety and depressive disorders. Hence, parents were more reliable when reporting about anxiety and depressive disorders whereas children were more reliable than their parents when reporting about disruptive and substance disorders.     

Sex differences in dynamic spatial ability: The unsolved question of performance factors

Males and females differ in several cognitive abilities, although the largest gap can be found in spatial ability. Some published studies make the claim that performance factors, which can be either subject- or task-related variables, explain these differences. However, previous studies in which performance factors were measured have focused on static spatial tests. Little is known about the role of performance factors in dynamic spatial tasks. In the present study, we analyzed a sample of 2624 university graduates to test the role of three performance factors (response latency, response frequency, and invested time) derived from the Spatial Orientation Dynamic Test-Revised (SODT-R; Santacreu, 1999). The results showed that males and females appear to cope with the dynamic task in different ways. However, males outperformed females even when the effects of the performance factors were partialed out; that is, the assessed performance factors did not explain much of the sex-related variance. Alternative ways of measuring performance factors will be needed if they are to explain sex differences in dynamic spatial ability.     

Perception of parental socialization strategies in adoptive and non-adoptive families

Although parental socialization styles have been investigated in recent years, little research has been carried out on the issue of parental styles in adoptive families. The aim of this research is to analyse parental styles both from the point of view of the parents and of adopted and non-adopted adolescents, taking as covariables the adolescents' sex and age. The sample was made up of 55 adopted adolescents (20 boys and 35 girls with an age range of 11-17 years) and their 55 adoptive parents, and 402 non-adopted adolescents (200 boys and 202 girls with an age range of 11-17 years), and their 258 parents. Two scales evaluated parental styles: the Affect Scale and the Rules and Demands Scale. The results showed that, both from the point of view of the parents and of the adolescents, adoptive families are more affective, communicative and inductive, and less critical and indulgent than non-adoptive families. No differences were found between adopted and non-adopted adolescents on the Parents' Rigidity Scale.     

Dimensional structure of the Brief Symptom Inventory with Spanish college students

The Brief Symptom Inventory is designed to assess symptoms of psychological disorders in adolescents and adults. The dimensional structure of the inventory, using exploratory and confirmatory factor analyses, was examined with a cross-sectional design in a Spanish sample of college students ( N = 1,033, aged between 18 and 30 years old). Two hypotheses were tested: the original distribution of the items in nine factors, and the unidimensionality of the inventory. According to the results, a nine-factor structure seemed to be confirmed, although the strong intercorrelations found among the subscales indicated that these were measuring closely related constructs. The importance of cultural influences when assessing psychological symptoms and the need to develop national and sex norms for instruments that assess psychopathology, are also discussed.     

Cognitive behavioral weight-loss program for individuals with psychotic mental diseases

Overweight derived from the intake of new antipsychotic medication in order to treat schizophrenia is a growing problem. The main purpose of this study is to launch a cognitive behavioural program in outpatients. It is focused on the weight control of patients with chronic mental diseases, especially those diagnosed as psychotic, and who are under treatment in a Psychosocial Rehabilitation Centre. In this study, the results of an experimental group and a control group were compared. The experimental group was made up of 7 individuals, 3 males and 4 females, and the control group comprised 4 males and 4 females. The program had a duration of twelve sessions administered over a period of three months. Three months after concluding the program, both groups were followed up. The data obtained indicate the efficiency of the cognitive-behavioural treatment in the patients. The achievements of this project were, on the one hand, to significantly reduce the patients' weight and, on the other, to modify their nutritional and physical exercise habits.     

Factors associated with eating behavior in pre-adolescents

The goals of this study are the preliminary Spanish adaptation and validation of the following questionnaires: the Children's Eating Attitudes Test (ChEAT), the Lawrence Self-Esteem Questionnaire (LAWSEQ) and the Body Esteem Scale (BES). In addition, we studied bodily self-esteem in pre-adolescent children, and their possible relation to certain eating attitudes and general self-esteem. This study is cross-sectional, analytical and observational. The sample was made up of 457 participants, 55.14% boys and 44.86% girls aged between 8 and 12 (M = 10.14, SD = 1.30). A multivariate analysis of variance (Age x Sex) was carried out with the total scores of LAWSEQ, ChEAT, BES, BIA and BMI. Cronbach's alpha reliability coefficient was .76, .80, and .67 for ChEAT, BES, and LAWSEQ, respectively. The boys presented significantly higher total scores in the ChEAT than the girls. Of the sample, 10.4% (n = 45) scored over the cut-off point of the ChEAT: These subjects presented lower general and bodily self-esteem, a slimmer ideal image and a greater discrepancy between their real self and their social self.     

Family communication styles, attitude towards institutional authority and adolescents' violent behaviour at school

The purpose of present study is to analyse the relationship among certain family and school factors, adolescents' attitude towards institutional authority, and violent behaviour at school. The sample is composed of 1049 adolescents of both sexes and aged from 11 to 16 years old. Statistical analyses were carried out using structural equation modelling. Results indicate a close association between negative communication with father and violent behaviour in adolescence. Moreover, data suggest that teachers' expectations affect students' attitude towards institutional authority, which in turn is closely related to school violence. Finally, findings show an indirect influence of father, mother and teacher in adolescents' violent behaviour, mainly through their effect on family- and school-self-concept.     

Temperamental and personality variables in child and adolescent depressive symptomatology

In this study, we analyzed the relationship between temperament and personality factors and depression in children and adolescents. Temperament was assessed with the Dimensions of Temperament Survey Revised (DOTS-R), personality with the Big Five Questionnaire-Children (BFQ-C), and depressive symptomatology with the Children's Depression Inventory (CDI). The sample was made up of 535 participants (274 boys and 261 girls), aged 8 to 15 years. Results show that temperament and personality are significantly related to depressive symptomatology in children and adolescents. Those with difficult temperaments showed more depressive symptomatology, as did those with high levels of emotional instability or low levels of extraversion, openness, agreeableness or conscientiousness. Multiple regression analyses revealed greater relevance of personality variables than of temperament variables.     

Mapping the apetitive and aversive systems with emotional pictures using a block-design fMRI procedure

Negative emotional pictures from the International Affective Pictures System (IAPS) have been successful in mapping brain areas related to the aversive system. However, the capacity of positive emotional pictures to study the brain areas related to the appetitive system (i.e., nucleus accumbens, prefrontal cortex) is less established. In this study, we used a block fMRI design to investigate this issue, including emotional pictures as background while participants performed a vowel-consonant discrimination task. Importantly, participants were heterosexual males and all positive pictures were related to erotic couples, opposite-sex erotica, or romantic scenes. Negative pictures were similar to those used in previous studies. Results were consistent with previous studies using event-related designs, showing activation of amygdala, lateral prefrontal cortex, and occipito-temporal areas, but positive pictures showed a significant activation in the left nucleus accumbens. These findings provide evidence of the utility of block designs in emotional research (positive emotional pictures).     

Attitudes, learning experience and performance in mathematics: gender differences

In this paper, we used the data of Mathematics achievements from the sample of 13- year-old Spanish boys and girl who took part in the Second National Assessment of Educational Progress, carried out by the Educational Testing Service. With the aim of identifying variables related to high achievement, our goals are: 1) to analyse whether there are significant differences in 13-year-old Spanish boys and girls in their attitudes towards mathematics, their study strategies, and their performance; 2) to analyse the influence of their attitudes and study strategies on their performance, and to examine whether these relations are the same in boys and girls; 3) to propose a theoretical model that explains the relationship among the variables defined by means of structural equation modelling. The results show that: a) there are significant differences between boys and girls in the variables studied; b) it is not possible to reject the proposed model that relates study strategies and attitudes towards performance in mathematics; and c) the model tends to be stable both among boys and girls.
