The biopsychosocial approach to chronic pain: scientific advances and future directions

The prevalence and cost of chronic pain is a major physical and mental health care problem in the United States today. As a result, there has been a recent explosion of research on chronic pain, with significant advances in better understanding its etiology, assessment, and treatment. The purpose of the present article is to provide a review of the most noteworthy developments in the field. The biopsychosocial model is now widely accepted as the most heuristic approach to chronic pain. With this model in mind, a review of the basic neuroscience processes of pain (the bio part of biopsychosocial), as well as the psychosocial factors, is presented. This spans research on how psychological and social factors can interact with brain processes to influence health and illness as well as on the development of new technologies, such as brain imaging, that provide new insights into brain-pain mechanisms.     

Memory for moving and static images

Despite the substantial interest in memory for complex pictorial stimuli, there has been virtually no research comparing memory for static scenes with that for their moving counterparts. We report that both monochrome and color moving images are better remembered than static versions of the same stimuli at retention intervals up to one month. When participants studied a sequence of still images, recognition performance was the same as that for single static images. These results are discussed within a theoretical framework which draws upon previous studies of scene memory, face recognition, and representational momentum.     

Coping After Bone Marrow Transplantation: The Predictive Roles of Optimism and Dispositional Coping

Bone marrow transplantation (BMT) is an invasive and taxing treatment for certain cancers. This study investigated the psychological constructs of optimism and dispositional coping and their relative predictive role for situational coping. Participants were 85 cancer patients enrolled in a randomized clinical trial of T-cell depletion for prevention of graft-versus-host disease (GVHD) who completed baseline and 1-year interviews. Results of simultaneous regression analyses showed that optimism did not predict situational instrumental or palliative coping strategies but was negatively predictive of situational avoidant coping. Each of the three situational coping strategies was most strongly predicted by the corresponding dispositional coping strategy. This research was sponsored by the National Heart, Lung and Blood Institute: N01-HB-47095, N01-HB-47097, N01-HB-47094 and N01-HB-47098.     

Body posture effects on self‐evaluation: A self‐validation approach

Building on the notion of embodied attitudes, we examined how body postures can influence self‐evaluations by affecting thought confidence, a meta‐cognitive process. Specifically, participants were asked to think about and write down their best or worse qualities while they were sitting down with their back erect and pushing their chest out (confident posture) or slouched forward with their back curved (doubtful posture). Then, participants completed a number of measures and reported their self‐evaluations. In line with the self‐validation hypothesis, we predicted and found that the effect of the direction of thoughts (positive/negative) on self‐related attitudes was significantly greater when participants wrote their thoughts in the confident than in the doubtful posture. These postures did not influence the number or quality of thoughts listed, but did have an impact on the confidence with which people held their thoughts.

A Recursive Frame Qualitative Analysis of MFT Progress Note Tipping Points

Medically oriented psychotherapists typically record progress notes by articulating client symptoms, diagnoses, functional status, progress, and adherence to treatment plans. This orientation can challenge marriage and family therapists working from discursive or post-modern perspectives. Although there are discursive therapy friendly treatment planning guides, no published research on such practice exists. To address this gap the researchers conducted a recursive frame qualitative analysis of 206 de-identified progress notes from 30 completed cases seen by MFT master’s students learning discursive approaches to therapy in a university-based training clinic. Researchers found students noted problem to solution-focused discourse tipping or turning points in 20 cases with positive outcomes and no comparable shifts in 10 cases with negative or unclear outcomes.     

The Persistence-Strengthening Effects of DRA: An Illustration of Bidirectional Translational Research

We summarize a series of bidirectional research studies that demonstrate the persistence-strengthening effects of differential reinforcement of alternative behavior on problem behavior. We model a possible solution to this problem with rats followed by replication with a human clinical population. The importance of coordinated basic and applied research to stimulate new behavioral technologies is emphasized.     

Suppressing Unwanted Memories

ABSTRACT— When reminded of something we would prefer not to think about, we often try to exclude the unwanted memory from awareness. Recent research indicates that people control unwanted memories by stopping memory retrieval, using mechanisms similar to those used to stop reflexive motor responses. Controlling unwanted memories is implemented by the lateral prefrontal cortex, which acts to reduce activity in the hippocampus, thereby impairing retention of those memories. Individual differences in the efficacy of these systems may underlie variation in how well people control intrusive memories and adapt in the aftermath of trauma. This research supports the existence of an active forgetting process and establishes a neurocognitive model for inquiry into motivated forgetting.     

An overview of the literature on sexual harassment: Perpetrator,theory, and treatment issues

Sexual harassment has been recognized as a serious problem in the literature over the past 30 years. In this paper, we review the existing research surrounding the phenomenon of sexual harassment, paying particular attention to factors of relevance for understanding perpetrators of sexual harassment. We also provide an overview of the perplexing nature of sexual harassment and the various concerns that have surrounded the topic leading to its recognition. The different theoretical perspectives and models of sexual harassment (sociocultural, organizational, sex-role spillover, natural/biological, socio-cognitive, and four-factor) are also considered and reviewed. Finally, lack of empirical evidence and focus on assessment and treatment for harassers is recognized in this paper, and several suggestions are made for future research and treatment avenues relating to the sexual harasser.     

A cost-effective high-throughput digital system for observation and acquisition of animal behavioral data

We have designed and implemented a low-cost digital system using closed-circuit television cameras coupled to a digital acquisition system for the recording of in vivo behavioral data in rodents and for allowing observation and recording of more than 10 animals simultaneously at a reduced cost, as compared with commercially available solutions. This system has been validated using two experimental rodent models: one involving chemically induced seizures and one assessing appetite and feeding. We present observational results showing comparable or improved levels of accuracy and observer consistency between this new system and traditional methods in these experimental models, discuss advantages of the presented system over conventional analog systems and commercially available digital systems, and propose possible extensions to the system and applications to nonrodent studies.
