Effect of pulsating electromagnetic field therapy on cell volume and phagocytosis activity in multiple sclerosis and migraine

PEMF treatment was studied in 10 patients with multiple sclerosis and 10 patients with migraine. In both patients' groups a single treatment induced a significant rise of yeast particle uptake by blood granulocytes. The percentage of phagocytizing cells was increased in migraine patients only. In both patients' groups 20 PEMF treatments caused a reduction of particle uptake, whereas the percentage of phagocytizing cells remained unchanged. In migraine patients the opsonic capacity of serum and the mean cell volume of erythrocytes, lymphocytes and granulocytes were initially reduced, but increased during the course of 20 PEMF treatments. The biphasic changes of cell volume and phagocytic activity are interpreted as a result of counter-regulation of the organism in response to the primary PEMF effect.     

Disentangling executive functions and memory processes in event‐based prospective remembering after brain damage: A neuropsychological study

Successful prospective remembering (PR) comprises at least two components: one retrospective component that refers to the encoding and retrieval of the content of the intention and a second prospective component that involves the retrieval of the intended action at the appropriate moment. Whereas the retrospective component is very similar to memory skills like learning and retention of new information, the prospective component is thought to rely mainly on executive function. Head injuries can disturb PR during both of these stages. To disentangle the relative impact of executive functions and retrospective memory processes on PR we embedded a PR task in a 2‐back verbal working memory paradigm. Fifty‐six neurological patients with brain damage of various aetiologies were divided pre‐experimentally into four groups on the basis of their delayed recall Index in the Wechsler Memory Scale‐Revised (WMS‐R, indicating absence or presence of deficits in retrospective memory functions) and their age‐corrected score in the Behavioural Assessment of the Dysexecutive Syndrome (BADS, indicating absence or presence of deficits in executive functions). Additionally, 19 controls matched for age and education were examined. We found that patients with deficits in executive functions detected fewer cues than any other group irrespective of their retrospective memory performance. However, eight patients with severe anterograde memory deficits could retain neither the intention nor its content. Thus, intactness of the retrospective component seems to be a necessary but not sufficient prerequisite for successful prospective remembering. For the execution of the intended action itself executive functions play a critical role.     

Positive effects of subclinical depression in prospective memory and ongoing tasks in young and old adults

Results reported in the literature show that depression can have either negative or neutral effects on prospective memory (PM). The goal of the present study was to broaden the analysis of depression-related effects on PM, with regard to the possibility that subclinical depression may have positive influence on PM. A total of 120 participants from four groups (young/old, subclinically depressed/non-depressed) completed event- and time-based PM tasks embedded in the linear orders task or stories task, respectively. In the event-based PM task no effects of depression were found, whereas depressed participants were more accurate in the time-based PM task, where higher monitoring during the last minute of the task was observed. It was also found that depressed participants built a mental model in the linear orders task more accurately than controls. Results of the present study are discussed with reference to the analytical rumination hypothesis.     

Wohlbefinden,Burn-out und Ressourcen bei Psychotherapeuten

Background

Well-being and its correlates have rarely been investigated in psychotherapists. Results from research on other occupational groups have shown that subjective and work-related well-being are both associated with performance and motivation as well as with mental and physical health. Therefore, personal and job-related resources of practicing psychotherapists were investigated in this study in order to assess their associations with well-being.

Method

A total of 771 psychotherapists filled in an online questionnaire including questions concerning well-being (WHO-Five Well-being Index, WBI-5), burnout (Maslach Burnout Inventory, MBI), and personal (Psychological Capital Questionnaire, PCQ) as well as job-related (Dutch Questionnaire on Work Experience, VBBA) resources.

Outcomes

Of the participants 45?% reported that they were suffering from high emotional exhaustion. Over 30?% reported a reduced subjective well-being, while more extensive professional experience was associated with better well-being. Psychotherapists reported optimism and hope to be the most important personal resources, whereas opportunities for personal and professional development were the most important job-related resources.

Conclusions

The study identified personal and job-related resources which may be relevant for different aspects of well-being in psychotherapists.     

Symptom structure in obsessive-compulsive disorder: a confirmatory factor-analytic study

Although obsessive-compulsive disorder (OCD) has long been a unitary diagnosis, there is much recent interest in its potential heterogeneity, as manifested by symptom subgroups. This study evaluated existing models of symptom structure in a sample of 203 individuals with OCD. Using confirmatory factor analysis, we examined the ability of each model to account for two levels of data: a priori symptom groupings (second-order) and individual symptoms, identified by the Yale-Brown Obsessive Compulsive Scale symptom checklist. Four models were examined: a single-factor, a two-factor (i.e., obsessions and compulsions), and two multidimensional models, comprising three and four factors. Adequate fit was found solely for the four-factor model--specifying obsessions/checking, symmetry/ordering, contamination/cleaning, and hoarding--but only at the second-order level; it did not account for relationships among discrete symptoms. Parameter estimates showed within-factor heterogeneity, as well as overlap between factors, most notably the two representing checking and contamination-related symptoms. The implications of these findings are discussed. Results provide evidence for the multidimensionality of OCD symptoms, but suggest that a comprehensive model has yet to be identified. They also point to the inadequacy of groupings based solely upon overt behavioural similarities (e.g., 'checking'). Recommendations are made for future research.     

A Closer Look Into the Multi‐Layer Structure of Motivational Intensity Theory

Drawing on the idea that humans aim to avoid wasting energy that is important for survival, motivational intensity theory postulates that task difficulty and success importance determine energy investment. Additionally, the theory makes predictions on how task characteristics moderate the relationship between task difficulty, success importance, and energy investment. In this article, I will show how the different predictions of motivational intensity theory relate to one another and to what extent they can be derived from the fundamental principle of energy conservation. I will also discuss the application of the theory to effort mobilization and cardiovascular reactivity. Specifically, I will discuss the additional assumptions and predictions that are necessary to link these applications to motivational intensity theory’s basic rationale, the energy conservation principle.
