Self-concept and psychosocial adjustment in adolescence

This study analyses the relationship between a multidimensional measure of self-concept, Self-concept Form-5 Questionnaire (AF5), and a broad set of adolescents' psychosocial adjustment indicators. From the responses of 1,281 participants (53.7% females) aged 12 to 17 years ( M = 14.98 years, SD = 1.74 years), results indicated that higher self-concept scores corresponded to better psychological adjustment, good personal skills and fewer behavioral problems. Although a positive relationship between social self-concept and drug use was found, this significant relationship disappeared once the adolescent's age and sex was controlled for. These results support the idea that the self-concept is a basic theoretical construct closely related to the psychosocial adjustment in adolescence. Also this study helps explain some contradictory results reported in the literature (i.e., a positive relationship between social self-concept and drug use), by showing how the statistical control of a third variable effect (i.e., age) avoids reaching conclusions based on spurious relationships.     

Ambulatory group treatment for cocaine dependent patients combining cognitive behavioral therapy and motivational interviewing

Psychological interventions in cocaine dependent patients have demonstrated efficacy. Remarkable approaches are Contingency Management (CM) and Cognitive Behavioral Therapy (CBT). Lack of treatment adherence is the most important limitation. Motivational Interview (MI) has been shown to be an adherence enhancer. The objective of this study is to evaluate retention and abstinence in a combined CM and CBT group treatment in patients who have reached maintenance stage according to Prochaska and DiClemente's transtheoretical model (1982). Therefore, a longitudinal study was carried out with cocaine dependent patients with or without concomitant mental health disease. A 12-session open group was conducted weekly. Nineteen patients were included (78.9% men, mean age 36.6 years), 95% consumed intranasally and 47% had another psychiatric comorbidity. Treatment retention was 84%. During treatment and the first month of follow-up, all patients remained abstinent whereas at three months, 3 patients relapsed. These data confirm that using combined CM and CBT group therapy in cocaine dependents undergoing maintenance treatment enhances adherence and is effective to achieve abstinence.     

Development and validation of a scale to assess positive youth development values

This paper describes the development of a self-report scale for adolescents to assess positive youth development values. It presents a substantial number of psychometric results performed on a sample of 2,400 adolescents (1,068 boys and 1,332 girls) from 12 to 17 years ( M = 14.73, SD = 1.25), who were studying secondary education in Western Andalusia. The results provide evidence of the psychometric quality of items, cross-validity of a structure of eight first-order factors and three second-order factors, obtained through exploratory and confirmatory factor analysis, and adequate reliability. This study concludes that the scale presents adequate evidence of validity and reliability that allows assessment, especially in school contexts, of a broad set of values of particular relevance to positive youth development.     

Spanish adaptation of the EAS Temperament Survey for the assessment of child temperament

Better understanding of child temperament is essential, as it may predict subsequent development of psychopathology. Questionnaires which have been adapted to Spanish population include a rather restricted age range. The Emotionality Sociability and Activity (EAS) Temperament Survey has been widely used in child temperament genetic research. A Spanish version of the scale was administered to a sample of 229 mothers and to their children at 18 and 42 months of age. Its psychometric features were examined. Results showed accuracy indices akin to that obtained in prior studies. Findings suggest a three-factor structure for the assessment of temperament.     

Exposure to severe urban air pollution influences cognitive outcomes, brain volume and systemic inflammation in clinically healthy children

Exposure to severe air pollution produces neuroinflammation and structural brain alterations in children. We tested whether patterns of brain growth, cognitive deficits and white matter hyperintensities (WMH) are associated with exposures to severe air pollution. Baseline and 1 year follow-up measurements of global and regional brain MRI volumes, cognitive abilities (Wechsler Intelligence Scale for Children-Revised, WISC-R), and serum inflammatory mediators were collected in 20 Mexico City (MC) children (10 with white matter hyperintensities, WMH⁺, and 10 without, WMH⁻) and 10 matched controls (CTL) from a low polluted city. There were significant differences in white matter volumes between CTL and MC children - both WMH⁺ and WMH⁻ - in right parietal and bilateral temporal areas. Both WMH⁻ and WMH⁺ MC children showed progressive deficits, compared to CTL children, on the WISC-R Vocabulary and Digit Span subtests. The cognitive deficits in highly exposed children match the localization of the volumetric differences detected over the 1 year follow-up, since the deficits observed are consistent with impairment of parietal and temporal lobe functions. Regardless of the presence of prefrontal WMH, Mexico City children performed more poorly across a variety of cognitive tests, compared to CTL children, thus WMH⁺ is likely only partially identifying underlying white matter pathology. Together these findings reveal that exposure to air pollution may perturb the trajectory of cerebral development and result in cognitive deficits during childhood.     

Insufficient Referral for Genetic Counseling in the Management of Hereditary Haemochromatosis in Portugal: A Study of Perceptions of Health Professionals Requesting HFE Genotyping

There is a general consensus that HFE- related Hereditary Haemochromatosis (HFE-HH) should be diagnosed at early stages in pre-symptomatic individuals, in order to prevent the most severe consequences of iron overload. In Portugal, despite an increasing number of requests for genetic diagnosis of this rare disease, there is not a corresponding increase in requests for genetic counselling. The objective of the present study was to evaluate physicians’ main motivations for requesting HFE genotyping or genetic counselling for HFE-HH. We assessed current medical practices regarding family testing and diagnosis and discuss whether these can be improved in order to increase the effectiveness of disease prevention. Our results show there is a general lack of knowledge about the selection of patient cases that should be sent for genetic counseling or for molecular testing of HFE-HH by physicians (especially by general practitioners). The lack of family-based screening may indirectly compromise the efficiency of disease prevention in terms of early diagnosis and treatment. We concluded it is necessary to circulate more information about Hereditary Haemochromatosis among health professionals in order to improve strategies for its early diagnosis.     

The Role Maturity of Parents of Emerging Adult Children: Validity of a Parental Maturity Measure

Parental maturity refers to parents’ ability to see their child as an independent adult with limitations and needs, and relate to him/her accordingly. In this study, we had two main aims: (a) develop a measure of parental maturity and test its construct validity in a sample of middle-aged parents with an emerging adult child, and (b) examine how the dimensions of parental maturity varied with a child’s gender and life course transitions (i.e., employment and leaving the parental home). A sample of 343 Portuguese parents (187 mothers and 156 fathers) aged 40–68 participated in this study. Factorial validity of the Parental Maturity Measure was tested using exploratory and confirmatory factor analyses and measurement invariance across mothers and fathers. Results gave support for a two-factor measure—Comprehending (6 items) and Letting Go (4 items)—with an equivalent meaning across parents. Dimensions of parental maturity were associated with differentiated and positive parent–child relationship qualities, but were quite independent of the child’s gender and life course transitions.     

Why the Wrongness of Killing Innocents is Not a Universal Moral Certainty

In this paper, I argue that the certainty about the wrongness of killing must not be considered as a universal, but as a local one. Initially, I show that there exist communities in which the wrongness of killing innocents is not a moral certainty and that this kind of case cannot be justified by arguing that such people are psychopaths. Lastly, I argue that universal certainties do not admit of exceptions: thus, the fact that some exceptional cases affect the certainty that killing innocents is wrong, leads me to conclude that it is a local certainty.
