Monitoring stress among internal medicine residents: an experience-driven,practical and short measure

Residents experience severely high levels of stress, depression and burnout, leading to perceived medical errors, as well as to symptoms of impairment, such as chronic anger, cognitive impairment, suicidal behavior and substance abuse. Because research has not yet provided a psychometrically robust population-specific tool to measure the level of stress of medicine residents, we aimed at building and validating such a measure. Using an inductive scale development approach, a short, pragmatic measure was built, based on the interviews of 17 medicine residents. The Internal Medicine Residency Stress Scale (IMRSS) was then administered in a sample of 259 internal medicine residents (199 females, 60 males, M_Age = 25.6) along with the Hospital Anxiety and Depression Scale, Maslach Burnout Inventory, Satisfaction With Life Scale and Ways of Coping Checklist. The IMRSS showed satisfactory internal reliability (Cronbach’s α = .86), adequate structural validity – studied through Confirmatory Factor Analysis (χ²/df = 2.51, CFI = .94; SRMR = .037, RMSEA = .076) – and good criterion validity – the IMRSS was notably strongly correlated with emotional exhaustion (r = .64; p < .001) and anxiety (r = .57; p < .001). Because of its short length and robust psychometric qualities, the use of the IMRSS is recommended to quickly and frequently assess and monitor stress among internal medicine residents.     

Telling things apart: the distance between response keys influences categorization times

People use spatial distance to talk and think about differences between concepts, and it has been argued that using space to think about different categories provides a scaffold for the categorization process. In the current study, we investigated the possibility that the distance between response keys can influence categorization times in binary classification tasks. In line with the hypothesis that distance between response keys can facilitate response selection in a key-press version of the Stroop task, our results showed that responses on incongruent Stroop trials were significantly facilitated when participants performed the Stroop task with response keys located far apart, compared with when they performed the task with response keys located close together. These results support the idea that the spatial structuring of response options facilitates categorizations that require cognitive effort, and that people can incorporate environmental structures such as spatial distance in their thought processes. Keeping your hands apart might actually help to keep things apart in your mind.     

Validation of distinct amnesic and executive type memory deficit in a psychiatric sample based on retrieval performance

Studies of localized brain dysfunctions have revealed connections between patterns of cognitive dysfunction and specific profiles of memory impairment. The amnesic type of memory impairment is defined by deficits in both free recall and recognition memory, whereas the dysexecutive memory impairment is characterized by retrieval deficits, i.e. a disproportional impairment in free recall relative to recognition memory. The present study tests whether classifications of psychiatric patients into recall impaired only (= RO group) and Recall and Recognition impaired (= RR group) correspond to the executive type and amnesic type of memory impairment. The alternative hypothesis is that the two groups merely differ in degree of neuropsychological and psychiatric disturbance. Forty-four subjects impaired on California Verbal Learning Test (CVLT) were selected from a larger database of 103 impaired and non-impaired subjects with schizophrenia or recurrent major depression. Subjects were classified into RO and RR groups and compared on measures of memory strategy (recency effect and interference on CVLT), overall neuropsychological function (Stroop Test and WAIS-R similarity) and psychiatric symptom load (positive and negative symptoms). Repeated measures ANOVA showed no effects of group, i.e. the RR group did not perform consistently below the RO group with regard to memory strategy, neuropsychological function or psychiatric symptom load. Two out of three analyses showed group x test interaction, supporting the dissociation of distinct executive and amnesic profiles among psychiatric patients. The RO group was more susceptible to interference but had better recency score than the RR group. The RO had higher negative symptoms while the RR group had higher positive symptoms.     

The liabilities of mobility: a selection pressure for the transition to consciousness in animal evolution

The issue of the biological origin of consciousness is linked to that of its function. One source of evidence in this regard is the contrast between the types of information that are and are not included within its compass. Consciousness presents us with a stable arena for our actions-the world-but excludes awareness of the multiple sensory and sensorimotor transformations through which the image of that world is extracted from the confounding influence of self-produced motion of multiple receptor arrays mounted on multijointed and swivelling body parts. Likewise excluded are the complex orchestrations of thousands of muscle movements routinely involved in the pursuit of our goals. This suggests that consciousness arose as a solution to problems in the logistics of decision making in mobile animals with centralized brains, and has correspondingly ancient roots.     

When love is not blind: Rumination impairs implicit affect regulation in response to romantic relationship threat

The present research examined how rumination influences implicit affect regulation in response to romantic relationship threat. In three studies, the disposition to ruminate impaired the ability to maintain positive feelings about the romantic partner in the face of explicit or implicit reminders of relationship threatening events. In Study 1, a high disposition to ruminate was correlated with impaired down-regulation of negative feelings toward the partner in response to a hurtful relationship incident. Two follow-up studies manipulated relationship threat explicitly through an experiential recall procedure (Study 2) or implicitly through a subliminal evaluative-conditioning procedure (Study 3). In both studies only individuals with low disposition to ruminate were able to ward off negative feelings and maintain positive feelings toward the partner. These findings illuminate the role of implicit affect regulation in the context of relationship threat—and how it is inextricably connected with the processes underlying rumination.     

Consciousness without Bodies: Rethinking the Power of the Visualised Brain

This article examines the possibility of the futuristic assumption that the human mind will converge with artificial intelligence technology to create an enhancement of consciousness. By studying how a correlation between consciousness and the brain is made through visual tools that are used in neuroscience, this article elaborates on how these findings affect research that is done in philosophy on the concept of consciousness. This article proposes a new approach on studying the brain, by examining it as a theoretical object, which gives every research field the possibility to argue over the truth in the images that are created of the brain.     

Prediction of symptoms of emotional distress by mood regulation expectancies and affective traits

Three studies examined negative mood regulation expectancies (NMRE) and affective traits as independent predictors of self‐reported symptoms of emotional distress. NMRE represent individuals' beliefs that they can alleviate unpleasant emotional states. Stronger NMRE are associated with more adaptive coping, more positive cognition during negative moods, more effective responses under stress and less emotional distress. Affective traits represent long‐term tendencies toward particular affective experiences; they confer risk for specific symptoms of emotional distress. In Study 1, NMRE, trait negative affect (TNA) and trait positive affect (TPA) were all independently associated with depression among students and staff of a German university. In Study 2, in prospective analyses among U.S. college students traits exhibited hypothesised relationships with anxiety and depressive symptoms, and NMRE uniquely predicted anhedonic depression. Study 3 revealed independent prediction of change in symptoms over time by NMRE among U.S. college students, whereas traits were not associated with change in distress, anxiety and depression symptoms. Results suggest independent roles for NMRE and traits in the development of depression and anxiety symptoms and highlight the importance of NMRE as a potential target of therapeutic intervention in the process of symptom change.     

The assessment of the social cognition and object relations scale on TAT and interview data

This study examines the reliability and convergent validity of 2 versions of the Social Cognition and Object Relations Scale (SCORS), one for use with Thematic Apperception Test narratives (SCORS-TAT; Westen, 1990) and one for use with clinical interview data (SCORS-CDI; Westen, Barends, Leigh, Mendel, & Silbert, 1990 ). Four SCORS dimensions were evaluated. Data were collected in a psychiatric sample (N = 74). Results show that although interrater reliability was good for all dimensions, internal consistency was low, especially for the affective dimensions. Structural equation modeling, in which a model with 2 factors (i.e., SCORS-TAT and SCORS-CDI) and 4 dimensions each was tested, indicated low convergence between corresponding dimensions of SCORS-TAT and SCORS-CDI. Correlational analyses suggested that this was due to a strong method factor. Regression analyses, however, revealed that the presence of a personality disorder operated as a moderator for convergence between corresponding cognitive-structural dimensions.
