- The tendency to interpret ambiguous everyday situations in a relatively negative manner (negative interpretation bias) is central to cognitive models of depression. Limited tools are available to measure this bias, either experimentally or in the clinic. This study aimed to develop a pragmatic interpretation bias measure using an ambiguous scenarios test relevant to depressed mood (the AST-D).(1) In Study 1, after a pilot phase (N = 53), the AST-D was presented via a web-based survey (N = 208). Participants imagined and rated each AST-D ambiguous scenario. As predicted, higher dysphoric mood was associated with lower pleasantness ratings (more negative bias), independent of mental imagery measures. In Study 2, self-report ratings were compared with objective ratings of participants' imagined outcomes of the ambiguous scenarios (N = 41). Data were collected in the experimental context of a functional Magnetic Resonance Imaging scanner. Consistent with subjective bias scores, independent judges rated more sentences as negatively valenced for the high versus low dysphoric group. Overall, results suggest the potential utility of the AST-D in assessing interpretation bias associated with depressed mood. (C) 2011 Elsevier Ltd. All rights reserved.

- Therapy with mental images is prevalent in the field of chronic pain, and this has been the case for centuries. Yet few of the recent advances in the cognitive behavioural understanding of spontaneous (i.e. intrusive) mental imagery have been translated to this field. Such advances include imagery as a component of a psychopathological process, as an emotional amplifier and as a cognitive therapeutic target in its own right. Hence very little is known about the contents, prevalence and emotional impact of spontaneous mental imagery in the context of chronic pain. This article discusses the evidence in favour of spontaneous imagery being a potentially important part of patients' pain experience, and makes a case, based on neurophysiological findings, for imagery having an impact on pain perception. Furthermore, it presents how mental imagery has been used in the treatment of chronic pain. A case report illustrates further how spontaneous negative imagery linked to pain can be distressing, and how this might be addressed in therapy. Additionally, the case report demonstrates the spontaneous use of coping imagery, and raises a discussion of how this might be enhanced.

- Background: Depressed mood alters the pain experience. Yet, despite its clear clinical relevance, little is known about the cognitive and neural mechanisms underlying this phenomenon. We tested an experimental manipulation to unravel the interaction between depressed mood and pain. We hypothesized that dysregulation of the neural circuitry underlying emotion regulation is the mechanism whereby pain processing is affected during depressed mood. Methods: Using functional magnetic resonance imaging, we compared the effects of sad and neutral cognitive mood inductions on affective pain ratings, pain-specific cognitions, and central pain processing of a tonic noxious heat stimulus in 20 healthy volunteers. Results: The increase in negative pain-specific cognitions during depressed mood predicted the perceived increase in pain unpleasantness. Following depressed mood induction, brain responses to noxious thermal stimuli were characterized by increased activity in a broad network including prefrontal areas, subgenual anterior cingulate cortex, and hippocampus, as well as significantly less deactivation when compared with pain responses in a neutral mood. The participants who reported the largest increase in pain unpleasantness after the sad mood induction showed greater inferior frontal gyrus and amygdala activation, linking changes in emotion regulation mechanisms with enhancement of pain affect. Conclusions: Our results inform how depressed mood and chronic pain co-occur clinically and may serve to develop and translate effective interventions using pharmacological or psychological treatment.

- Objective. To ascertain whether a small sample of patients with chronic pelvic pain experienced any pain-related cognitions in the form of mental images. Patients. Ten women with chronic pelvic pain consecutively referred from a tertiary referral center by the physicians in charge of their treatment. Outcome measures. An interview was used to determine the presence, emotional valence, content, and impact of cognitions about pain in the form of Inventory (BPI), Pain Catastrophizing Scale (PCS), Spontaneous Use of Imagery Scale (SUIS), and Hospital Anxiety and Depression Scale (HADS) were completed. Results. In a population of patients with a prolonged duration of pain and high distress, all patients reported experiencing cognitions about pain in the form of mental images. For each patient, the most significant image was both negative in valence and intrusive. The associated emotional-behavioral pattern could be described within a cognitive behavioral therapy framework. Eight patients also reported coping imagery. Conclusion. Negative pain-related cognitions in the form of intrusive mental imagery were reported by women with chronic pelvic pain. Targeting such imagery has led to interesting treatment innovation in the emotional disorders. Thus, imagery, hitherto neglected in pain phenomenology, could provide a novel target for cognitive behavioral therapy in chronic pain. These exciting yet preliminary results require replication and extension in a broader population of patients with chronic pain.

Tidskriftsartikel (refereegranskat)abstract
- Control interventions (often called "sham," "placebo," or "attention controls") are essential for studying the efficacy or mechanism of physical, psychological, and self-management interventions in clinical trials. This article presents core recommendations for designing, conducting, and reporting control interventions to establish a quality standard in non-pharmacological intervention research. A framework of additional considerations supports researchers' decision making in this context. We also provide a reporting checklist for control interventions to enhance research transparency, usefulness, and rigour.
