Determinants of representational and behavioral hyperactivity in patients with fibromyalgia syndrome.

Fibromyalgia is associated with a premorbid hyperactivity. This study examines how contextual and personality factors contribute to premorbid hyperactivity. A total of 45 patients completed questionnaires. The results show that the number of children and the basic bodily needs neglect (and their interaction) explain nearly 50 percent of the variance of hyperactivity. The neglect toward bodily needs completely mediates the relation between self-oriented perfectionism and hyperactivity. This study suggests that hyperactivity itself would not have a pathological value, but that the neglect of basic bodily needs would represent a vulnerability factor in a hyperactive premorbid lifestyle in fibromyalgia patients.

"Our Country Needs a Strong Leader Right Now": Economic Inequality Enhances the Wish for a Strong Leader.

Societal inequality has been found to harm the mental and physical health of its members and undermine overall social cohesion. Here, we tested the hypothesis that economic inequality is associated with a wish for a strong leader in a study involving 28 countries from five continents (Study 1, N = 6,112), a study involving an Australian community sample (Study 2, N = 515), and two experiments (Study 3a, N = 96; Study 3b, N = 296). We found correlational (Studies 1 and 2) and experimental (Studies 3a and 3b) evidence for our prediction that higher inequality enhances the wish for a strong leader. We also found that this relationship is mediated by perceptions of anomie, except in the case of objective inequality in Study 1. This suggests that societal inequality enhances the perception that society is breaking down (anomie) and that a strong leader is needed to restore order (even when that leader is willing to challenge democratic values).

Revisiting the Measurement of Anomie.

Sociologists coined the term "anomie" to describe societies that are characterized by disintegration and deregulation. Extending beyond conceptualizations of anomie that conflate the measurements of anomie as 'a state of society' and as a 'state of mind', we disentangle these conceptualizations and develop an analysis and measure of this phenomenon focusing on anomie as a perception of the 'state of society'. We propose that anomie encompasses two dimensions: a perceived breakdown in social fabric (i.e., disintegration as lack of trust and erosion of moral standards) and a perceived breakdown in leadership (i.e., deregulation as lack of legitimacy and effectiveness of leadership). Across six studies we present evidence for the validity of the new measure, the Perception of Anomie Scale (PAS). Studies 1a and 1b provide evidence for the proposed factor structure and internal consistency of PAS. Studies 2a-c provide evidence of convergent and discriminant validity. Finally, assessing PAS in 28 countries, we show that PAS correlates with national indicators of societal functioning and that PAS predicts national identification and well-being (Studies 3a & 3b). The broader implications of the anomie construct for the study of group processes are discussed.

The association between depression and craving in alcohol dependency is moderated by gender and by alexithymia factors.

Alexithymia is a multifaceted personality trait that involves difficulties in identifying and describing feelings to others, a poor fantasy life and an externally oriented cognitive style. Alexithymia has been described as a vulnerability factor for mental and physical diseases. We investigated in a group of 158 alcohol-dependent patients (103 men, 55 women) the association between depression and craving for alcohol when these patients were starting a detoxification program, and the moderating impact of gender and alexithymia on this relation. We first found an interaction between depression and gender in the prediction of craving in the sense that only for women an increase in depressive mood was related to an increase in total craving. When examining gender separately, we found that alexithymia factors acted as moderators. For women, the link between depression and craving was strengthened for the ones scoring higher on "difficulties describing feelings". But for men, the link between depression and craving was reduced for the ones scoring higher on "externally-oriented thinking". These findings suggest that in some cases that need to be identified more systematically in the future, the "externally-oriented thinking" alexithymia factor can exert - at least in the short term - some protective effects.

Evidence of Contrasting Patterns for Suppression and Reappraisal Emotion Regulation Strategies in Alexithymia.

Alexithymia generally refers to difficulties in identifying and describing emotions. In this paper, two studies explored whether the emotion deficits observed in alexithymia may be related to the use of emotion regulation strategies. Relations with various sociodemographic variables were also explored. In the first study, 255 students completed the Emotion Regulation Questionnaire (ERQ) and the Toronto Alexithymia Scale-20. For the second study, 1107 participants from the general population completed the ERQ and the Bermond-Vorst Alexithymia Questionnaire. Results demonstrated that alexithymia was related to the use of a suppression strategy and in particular to difficulties verbalizing emotions, suggesting that the capacity to communicate and name one's emotion is a central aspect in alexithymia. Concerning sociodemographic variables, alexithymia and the use of a suppression strategy were found to be related to age and to be higher in males. The results of these studies and their clinical implications for treatment are discussed.

The body language: The spontaneous influence of congruent bodily arousal on the awareness of emotional words.

Nowadays, the idea of a reciprocal influence of physiological and psychological processes seems to be widely accepted. For instance, current theories of embodied emotion suggest that knowledge about an emotion concept involves simulations of bodily experienced emotional states relevant to the concept. In line with this framework, the present study investigated whether actual levels of physiological arousal interact with the processing of emotional words. Participants performed 2 blocks of an attentional blink task, once after a cycling session (increased arousal) and once after a relaxation session (reduced arousal). Concretely, participants were instructed to detect and report 2 target words (T1 and T2) presented among a series of nonword distractors. T1 and T2 were either neutral, high arousal, or low arousal words. Results revealed that increased physiological arousal led to improved reports of high arousal T2 words, whereas reduced physiological arousal led to improved reports of low arousal T2 words. Neutral T2 remained unaffected by the arousing conditions. These findings emphasize that actual levels of physiological arousal modulate the cognitive access to arousal (in-)congruent emotional concepts and suggest a direct grounding of emotion knowledge in our bodily systems of arousal.

Involvement of hyperprolinemia in cognitive and psychiatric features of the 22q11 deletion syndrome.

Microdeletions of the 22q11 region, responsible for the velo-cardio-facial syndrome (VCFS), are associated with an increased risk for psychosis and mental retardation. Recently, it has been shown in a hyperprolinemic mouse model that an interaction between two genes localized in the hemideleted region, proline dehydrogenase (PRODH) and catechol-o-methyl-transferase (COMT), could be involved in this phenotype. Here, we further characterize in eight children the molecular basis of type I hyperprolinemia (HPI), a recessive disorder resulting from reduced activity of proline dehydrogenase (POX). We show that these patients present with mental retardation, epilepsy and, in some cases, psychiatric features. We next report that, among 92 adult or adolescent VCFS subjects, a subset of patients with severe hyperprolinemia has a phenotype distinguishable from that of other VCFS patients and reminiscent of HPI. Forward stepwise multiple regression analysis selected hyperprolinemia, psychosis and COMT genotype as independent variables influencing IQ in the whole VCFS sample. An inverse correlation between plasma proline level and IQ was found. In addition, as predicted from the mouse model, hyperprolinemic VCFS subjects bearing the Met-COMT low activity allele are at risk for psychosis (OR = 2.8, 95% CI = 1.04-7.4). Finally, from the extensive analysis of the PRODH gene coding sequence variations, it is predicted that POX residual activity in the 0-30% range results into HPI, whereas residual activity in the 30-50% range is associated either with normal plasma proline levels or with mild-to-moderate hyperprolinemia.
