Multiaxial taxonomy of fibromyalgia syndrome patients

Pain, disability, and depression are present in various degrees in patients with fibromyalgia syndrome. Cluster analysis was used in this research to ascertain the existence of subgroups of patients in a fibromyalgia sample based on these variables. Two clusters were defined: one characterized by high levels of pain, disability, and depression (n=51) and another characterized by low levels of pain, disability, and depression (n=67). Multivariate analysis of variance (MANOVA) confirmed differences between clusters on these health status factors and a second MANOVA revealed that the subgroup with a poorer health status reported greater passive coping, helplessness, and stress, and less satisfaction with social support, than the subgroup with better health status. Logistic regression indicated that the best discriminator of subgroup membership was helplessness. These results suggest that different approaches to patient management, particularly intervention strategies aimed at reducing helplessness, may be beneficial for patients with high levels of pain, disability, and depression.     

The relationship between active hand and ear advantage in the native and foreign language

In an experimental design involving two auditorily presented competing commands (one to each ear), 144 right-handed subjects (72 male and 72 female) were asked to provide motor responses. Half of each group of subjects was responding with their right hand and the other half with the left. The test was applied in the subjects' native language (Croatian) and in English, which they had learned as a foreign language. Ear advantage was determined by calculating laterality indices from the order of responding to the commands. On average, right-ear advantage was found in all conditions. Analysis of results revealed the effect of the active hand in Croatian (with significant decrease in the right-ear advantage when using the left hand). The same trend failed to reach significance in English. In responses to English stimuli, there was a significant effect of gender (with men exhibiting a lower right-ear advantage than women). The same trend was not significant for Croatian stimuli. The consistently lower right-ear advantage found in male subjects is contrary to the traditional assumptions that men are more lateralized than women and warrants further investigation.     

Stress applied during primary immunization affects the secondary humoral immune response in the rat: involvement of opioid peptides

The effect of unpredictable, inescapable and uncontrollable electric tail shocks (ES) on the humoral immune response to bovine serum albumin (BSA) was investigated in the rat. Contributions of the procedures that accompany shock delivery, such as witnessing the ES procedure (stress witnessing, SW) and exposure to the apparatus for shock delivery (apparatus control, AC) to the changes in specific immunity induced by ES were also tested. All procedures were applied during primary and/or secondary immunization. It was demonstrated that exposure to ES during primary immunization with BSA significantly suppressed specific anti-BSA antibody production after secondary and tertiary immunization with the same antigen. Exposure to the SW procedure during primary immunization with BSA enhanced the specific antibody level after secondary immunization, while exposure to the apparatus alone did not influence the development of either the primary or secondary humoral immune response to BSA. Both ES-induced suppression and SW-induced potentiation of the humoral immune response were partially inhibited by prior treatment with the opioid receptor antagonist naloxone. Additionally, treatments with the opioid peptides methionine- and leucine-enkephalin decreased anti-BSA antibody level, mimicking to some extent the effects of ES. It is suggested that ES and endogenous opioid peptides had long-term effects on humoral immunity through mechanisms involving immunologic memory.     

The Relationship Between Blood Lead,Bone Lead and Child Intelligence

We report associations between serial measures of blood lead and intelligence in children age 10–12 years, half heavily exposed to lead from the prenatal period onward, and half relatively unexposed. For a subsample, we examine bone lead-IQ associations, comparing them with blood lead associations. Both blood and bone lead levels were associated with intelligence decrements, small relative to the contribution of social factors. For each doubling of Tib-Pb, Full Scale, Performance, and Verbal IQ decreased by an estimated 5.5, 6.2, and 4.1 points, respectively. Bone lead-IQ associations were stronger than those for blood lead, which nonetheless provide robust analogues. Current BPb, easy to obtain, provides a useful means for assessing Pb exposure/IQ associations.

The Structure of Adolescent Affective Well-Being: The Case of the PANAS Among Serbian Adolescents

The structure of affective well-being and the relationship between positive affect (PA) and negative affect (NA) have rarely been examined among adolescents. The aim of the present research was to investigate the question of bipolarity versus independence of PA and NA as measured by the PANAS across three studies in adolescent samples. The results of Study 1 (N = 1038) showed that a two-factor structure of the PANAS, with correlated PA and NA and allowed correlated errors between similarly worded items provided the best fit to data. Study 2 included three independent samples (total N = 1071), and showed that PA and NA differed in terms of their relationship to various well-being indicators. Study 3 (N = 482) tested the predictive validity of PA and NA in a 5 month follow-up design, and showed that both PA and NA had independent predictive benefits for depression, risky behaviors and life satisfaction, and that PA had no unique role in the prediction of stress and anxiety, while NA had no unique role in the prediction of academic achievement. The results of the present research provided strong support for the relative independence of PA and NA as measured by the PANAS among adolescents.

Religiousness as a Protective Factor for Substance Use in Dance Sport

Although religiousness is found to be a significant protective factor in substance use, there is an evidential lack of studies of such in athletes. The aim of the study was to identify the predictive value of the religiousness and some social, educational, and sport factors on substance use in 43 sport dancers. An originally developed questionnaire for studying substance use and precipitation factors was applied. The Chi-square showed male dancers as more religious than females. Using the Spearman’s correlation, religiousness was found to be a significant protective factor in cigarette smoking, sport nutritional supplementation, and the likelihood of doping. Data were interpreted emphasizing the previous findings from the literature.     

Individual Differences in Affective Priming Effects: Any Links with Personality and Trait Affectivity?

Processing tendencies refer to individual differences in the automatic processing of affective stimuli. Using the affective priming paradigm one can tap these processing tendencies and differentiate positive and negative affective priming scores. In this study we used a classical evaluative decision task with nouns as primes and adjectives as targets to assess individual differences in positive and negative affective priming in two time points. Using Steyer’s (Steyer et al. in Methods of Psychological Research Online 2(1), 21–33, 1997) true intraindividual change modeling approach, the positive and negative priming scores were defined on a latent level. No significant relationships were found between positive affective priming and trait positive affect nor extraversion, as well as between negative affective priming and trait negative affect and neuroticism. As these findings are not in line with previous research (Robinson et al. in Emotion 10(5), 615–626, 2010; Robinson et al. in Personality and Individual Differences 42(7), 1221–1231, 2007) possible moderating influences are discussed.
