The Role of Self-Efficacy and Fear-Avoidance Beliefs in the Prediction of Disability

Both self-efficacy and fear-avoidance beliefs have been shown to be predictors of the level of disability in low back pain suffers. What is not clear from the literature, however, is whether the two constructs are differentially predictive of disability. The aim of this study was to investigate the relationship between pain self-efficacy and fear-avoidance beliefs and to determine whether they can explain unique variance in disability scores. One hundred and twenty-one people over the age of 18, suffering from chronic low back pain and receiving workers' compensation, completed the Pain Self-Efficacy Scale (PSEQ), the Fear Avoidance Beliefs questionnaire (FABQ), the Quebec Back Pain Disability Scale and a visual analogue scale for pain. The results show that, after controlling for pain, self-efficacy explained 24% of the variance in disability scores, and fear avoidance only a further 3.1%.     

Gender differences in facial imitation and verbally reported emotional contagion from spontaneous to emotionally regulated processing levels

Previous studies on gender differences in facial imitation and verbally reported emotional contagion have investigated emotional responses to pictures of facial expressions at supraliminal exposure times. The aim of the present study was to investigate how gender differences are related to different exposure times, representing information processing levels from subliminal (spontaneous) to supraliminal (emotionally regulated). Further, the study aimed at exploring correlations between verbally reported emotional contagion and facial responses for men and women. Masked pictures of angry, happy and sad facial expressions were presented to 102 participants (51 men) at exposure times from subliminal (23 ms) to clearly supraliminal (2500 ms). Myoelectric activity (EMG) from the corrugator and the zygomaticus was measured and the participants reported their hedonic tone (verbally reported emotional contagion) after stimulus exposures. The results showed an effect of exposure time on gender differences in facial responses as well as in verbally reported emotional contagion. Women amplified imitative responses towards happy vs. angry faces and verbally reported emotional contagion with prolonged exposure times, whereas men did not. No gender differences were detected at the subliminal or borderliminal exposure times, but at the supraliminal exposure gender differences were found in imitation as well as in verbally reported emotional contagion. Women showed correspondence between their facial responses and their verbally reported emotional contagion to a greater extent than men. The results were interpreted in terms of gender differences in emotion regulation, rather than as differences in biologically prepared emotional reactivity.     

Genetic and environmental influences on mothering of adolescents: a comparison of two samples

This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of positivity, negativity, control, and monitoring were used. The use of matched child-based and parent-based samples enabled passive and nonpassive genotype-environment (GE) correlations to be approximated, providing information about process. Passive GE correlations were suggested for mother's positivity and monitoring. For mother's negativity and control, primarily nonpassive GE correlations were suggested. In several cases, both types of GE correlation were indicated. Finally, observer ratings of negativity and monitoring were influenced only by environmental factors.     

Brain mechanisms involved in angry prosody change detection in school-age children and adults,revealed by electrophysiology

Voices transmit social signals through speech and/or prosody. Emotional prosody conveys key information about the emotional state of a speaker and is thus a crucial cue that one has to detect in order to develop efficient social communication. Previous studies in adults reported different brain responses to emotional than to neutral prosodic deviancy. The aim of this study was to characterize such specific emotional deviancy effects in school-age children. The mismatch negativity (MMN) and P3a evoked potentials, reflecting automatic change detection and automatic attention orienting, respectively, were obtained for neutral and emotional angry deviants in both school-age children (n = 26) and adults (n = 14). Shorter latencies were found for emotional than for neutral preattentional responses in both groups. However, whereas this effect was observed on the MMN in adults, it appeared in an early discriminative negativity preceding the MMN in children. A smaller P3a amplitude was observed for the emotional than for the neutral deviants at all ages. Overall, the brain responses involved in specific emotional change processing are already present during childhood, but responses have not yet reached an adult pattern. We suggest that these processing differences might contribute to the known improvement of emotional prosody perception between childhood and adulthood.     

Kandidaten in psychotherapeutischer Ausbildung

In the context of the discussion about a reform of psychotherapeutic training in Germany the question arises, which factors influence the decision of psychologists and physicians for a particular training. 343 candidates in psychodynamic, behavioural or psychoanalytic training were asked about their motives for the training, their professional objectives in general and their satisfaction with their choice of training. The candidates' decision for a particular training was associated with personal attitudes and professional goals, with the given information about psychotherapeutic treatment within their studies and with their field of study. For the most part, the respondents are not satisfied with the quality and quantity of information on psychotherapeutic treatment within their studies. Candidates in analytic training are altogether more satisfied with their choice of training and do not plan to start an additional psychotherapeutic training as often as candidates in behavioral training. The consequences of these results in particular for the medical and psychological curricula (a more balanced representation of psychotherapeutic methods) are discussed.     

Effects of US-Alone Presentations on Human Evaluative Conditioning

In the context of evaluative conditioning, the effects of additional presentations of the unconditioned stimulus (US) prior to conditioning (US preexposure) or after conditioning (US postexposure) were examined using between- and within-subjects control conditions. Two experiments that differed with respect to the nationality of the subjects were conducted. In both experiments, US-alone presentations reduced the magnitude of the evaluative response. The US pre- and postexposure effects were observed in subjects classified as aware as well as in subjects classified as unaware of the experimental contingencies. Another finding is that the evaluative conditioning procedure described by Martin and Levey (1978; Levey & Martin, 1975) resulted in reliable conditioning effects also in an American sample, thus extending the scope of that special evaluative conditioning paradigm. The findings are discussed in the context of recent models of classical and evaluative conditioning. Especially, the unexpected US postexposure effect gives rise to speculations concerning the learning process underlying evaluative conditioning.     

The Ecological Self: Metaphor and Developmental Experience?

The term ecological self, used within the fields of deep ecology and ecopsychology, is considered here from the viewpoint of developmental research and theory, within the context of contemporary relational psychoanalysis. Both developmental theory and more specifically our concept of health are explored with the inclusion of relatedness to the nonhuman world and an emphasis on embodiment and interactive experience. Illustrations and examples are drawn from research, clinical work with adults and the literature of natural history.     

Beyond the Frying Pan: Addressing Work Issues with Women in Therapy

In recent years, mental health practitioners have been exploring how women are balancing work and family. Given how this issue affects womens experiences in the corporate world and at home, marriage and family therapists are attempting to consider this concern as they treat female clients individually and within relational systems. Few articles and studies have examined the issues female employees face in the workplace and how the issues influence the therapeutic process. In this article, the authors examine the organizational, sociological, and cultural challenges women deal with at work and apply these areas to the therapeutic context. The authors present a case study of a female client enduring a difficult work situation, discussing how to view and approach this case from a feminist family therapy perspective.
