Validation of the Spanish SIRS With Monolingual Hispanic Outpatients

Psychologists are faced with formidable challenges in making their assessment methods relevant to growing numbers of Hispanic clients for whom English is not the primary or preferred language. Among other clinical issues, the determination of malingering has profound consequences for clients. In this investigation, we evaluated a Spanish translation of the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) with 80 Spanish-speaking Hispanic American outpatients. Using a between-subjects simulation design, the Spanish SIRS was found to produce reliable results with small standard errors of measurement. Regarding validity, very large effect sizes (mean Cohen’s d= 2.00) were observed between feigners and honest responders for the SIRS primary scales. We consider the potential role of the Spanish SIRS with reference to Spanish translations for other assessment instruments.     

Religious experience,religious orientation and schizotypy

The present study examined the relationship between religious orientation and schizotypy, with the prediction that intrinsic religiosity would be negatively associated with schizotypy, and religious experience and extrinsic religiosity would be positively associated with schizotypy. A total of 308 UK adults (132 men; 176 women) completed measures of religious experience, intrinsic orientation towards religion, extrinsic orientation towards religion, schizotypal personality traits and borderline personality. Though the present findings also suggest that the significant relationships between religiosity and schizotypy traits are fragmented, particularly by sex, the findings are consistent with theory that an intrinsic orientation towards religion is associated with lower levels of schizotypy, and religious experience and an extrinsic orientation towards religion is associated with higher levels of schizotypy.     

Spanish adaptation of the Psychological Well-Being Scales (PWBS)

The aim of this paper is to adapt to Spanish the D. van Direndonck version of Carol Ryff's Psychological Well-Being Scales, and to analyse its consistency and factorial validity. All the scales exhibited good internal reliabilities, with Cronbach alpha's ranging from 0.83 (Self-acceptance) to 0.68 (Personal growth). However, confirmatory factor analyses didn't corroborate the six-factor model (Self-acceptance, Positive relations, Autonomy, Environmental mastery, Purpose in life, and Personal growth) with a second order factor called Psychological Well-Being . To improve the psychometric properties, a new reduced version was proposed that indeed will facilitate the application. The scales of the new version maintain and raise its internal consistency (Cronbach alpha's 0.84 to 0.70). Furthermore, the scales shown an excellent fit to the theoretical model proposed by D. van Dierendonck.     

Forgiveness and happiness. the differing contexts of forgiveness using the distinction between hedonic and eudaimonic happiness

The aim of the present study was to examine the relationship between forgiveness and happiness using a two-dimensional model of happiness (hedonic and eudaimonic happiness). 224 United Kingdom students were administered the Enright Forgiveness Inventory, The Depression–Happiness Scale and the Oxford Happiness Questionnaire – Short-form. The present findings suggest that forgiveness accounts for statistically significant variance, albeit quite low, in both hedonic and eudaimonic happiness and the relationships may vary depending on which aspect of happiness is being considered. In terms of shorter-term hedonic happiness, the present findings suggest it is important not to engage in negative cognitions about the transgression. In terms of maintaining eudaimonic happiness, engaging in positive behaviours and feelings may lead to, be the result of, or be very much part of longer-term happiness.     

Activity-Dependent Activation of TrkB Neurotrophin Receptors in the Adult CNS

In this paper we have investigated the hypothesis that neural activity causes rapid activation of TrkB neurotrophin receptors in the adult mammalian CNS. These studies demonstrate that kainic acid-induced seizures led to a rapid and transient activation of TrkB receptors in the cortex. Subcellular fractionation demonstrated that these activated Trk receptors were preferentially enriched in the synaptosomal membrane fraction that also contained postsynaptic glutamate receptors. The fast activation of synaptic TrkB receptors could be duplicated in isolated cortical synaptosomes with KCl, presumably as a consequence of depolarization-induced BDNF release. Importantly, TrkB activation was also observed following pharmacological activation of brain-stem noradrenergic neurons, which synthesize and anterogradely transport BDNF; treatment with yohimbine led to activation of cortical TrkB receptors within 30 min. Pharmacological blockade of the postsynaptic α1-adrenergic receptors with prazosin only partially inhibited this effect, suggesting that the TrkB activation was partially due to a direct effect on postsynaptic cortical neurons. Together, these data support the hypothesis that activity causes release of BDNF from presynaptic terminals, resulting in a rapid activation of postsynaptic TrkB receptors. This activity-dependent TrkB activation could play a major role in morphological growth and remodelling in both the developing and mature nervous systems.     

Skipping breakfast,sedentarism and overweight in children

To show by use of path analysis how in children of 9 and 10 years of age the known relationship between breakfast and high body mass index (BMI) is mediated by sedentary leisure time activities. A random sample of 291 9-year-old and 10-year-old school children from the Principality of Asturias (Spain) was taken. A transversal design was used, their weight and height were measured and an individual standardized interview was carried out in which they were asked about their breakfast habits and the time they spent each week on sedentary leisure activities. Using path analysis, a model was tested in which breakfast habits and leisure time were the independent variables and the BMI was the dependent variable. The results showed that there was an inverse correlation between number of breakfasts and BMI and a direct correlation between the time spent on sedentary leisure activities and BMI. Path analysis showed that the relationship between the frequency with which breakfast was eaten and BMI was mediated by the time spent on sedentary leisure activities. The above appears to confirm the direct role played by failing to have breakfast in the pandemic of obesity as this habit tends to increase children’s BMI. This relationship is, however, mediated by sedentary leisure. According to the data compiled, being overweight in children can only be prevented by modifying not just one of the habits that have been associated with it, but rather the whole group of habits as these appear to make up an obesogenic cluster in which sedentary leisure and not having breakfast are included.
