The purpose of the present study was to determine the psychological impact of wisdom teeth removal and to identify the psychological risk factors for the development of dental anxiety and post-traumatic stress symptoms. Participants were 34 consecutive elective patients referred for surgical removal of a wisdom tooth under local anesthesia. Frequency of previous distressing dental events and general traumatic life events were assessed at baseline (t1), and emotional distress (pain, state anxiety and disturbance) immediately after treatment (t2). ⋯ Multivariate analysis revealed that previous exposure to distressing dental events and pre-operative anxiety level predicted anxiety level at t4, accounting for 71% of the variance. Severity of pain during treatment was a significant predictor variable of PTSD symptom severity at t4 (25% explained variance). The findings underline the importance of pain-free treatments and awareness of patients' individual predisposition to anxiety or trauma-related symptoms to reduce the risk of iatrogenic psychological harm.

There is increasing attention to the mechanisms underpinning maladaptive responses to bereavement. This study indexed self-defining memories in bereaved individuals with and without complicated grief (CG). Participants with and without complicated grief (N=40) were asked to describe three self-defining memories. ⋯ Both groups were equally likely to report their loved one's death as a self-defining moment, however, the no-CG group showed more evidence of benefit finding in their memory narratives and experienced less negative emotion on recall. The findings suggest that CG is associated with distinctive patterns of autobiographical memory that are linked to self-identity. The pattern is consistent with self-memory system models of autobiographical remembering, and suggests that grieving individuals who experience ongoing yearning for their loved one view their self-identity as more closely linked to the deceased are more distressed by memories involving the loss.

Depressed individuals display biased attention for emotional information when stimuli are presented for relatively "long" (e.g., 1s) durations. The current study examined whether attentional biases are sustained over a much longer period. Specifically, clinically depressed and never depressed young adults simultaneously viewed images from four emotion categories (sad, threat, positive, neutral) for 30s while line of visual gaze was assessed. ⋯ Time course analyses indicated that these biases were maintained over the course of the trial. Results suggest that depressed participants' attentional biases for dysphoric information are sustained for relatively long periods even when other emotional stimuli are present. Mood congruent information-processing biases appear to be a robust feature of depression and may have an important role in the maintenance of the disorder.

We know less about positive mental imagery than we do about negative mental imagery in depression. This study examined the relationship between depressed mood and the subjective experience of emotion in imagined events; specifically, prospective imagery, and imagery in response to emotionally ambiguous stimuli. One hundred and twenty-six undergraduates completed measures of depression, imagery vividness for future events, and a homograph interpretation task in which they generated images and subsequently rated image pleasantness and vividness. ⋯ We suggest that an imbalance in the inability to vividly imagine positive but not negative future events may curtail the ability of high dysphorics to be optimistic. High dysphoric individuals are further disadvantaged: even when they interpret ambiguity positively, the resulting images they generate are associated with less positive affect. Therapeutic strategies that address both such positive-specific imagery biases hold promise for depression treatment innovation.

The aim of the present study was to investigate the role of anxiety sensitivity (AS) as a factor relevant to pain and pain persistence. Two studies were conducted to examine the relationship between AS, body vigilance and the experience of pain in non-clinical samples. Study 1 investigated the relationship between AS and body vigilance that was operationalized by the detection latency for innocuous electrical stimuli; trait anxiety and neuroticism were also included as covariates. ⋯ No significant differences were found in pain and distress ratings. Results from both studies support the importance of AS in body vigilance and the experience of pain. The theoretical, preventive and clinical implications of these findings are discussed.
