Objective: To analyze gait patterns associated with sadness and depression. Embodiment theories suggest a reciprocal relationship between bodily expression and the way in which emotions are processed. Methods: In Study 1, the gait patterns of 14 inpatients suffering from major depression were compared with those of matched never-depressed participants. In Study 2, we employed musical mood induction to induce sad and positive mood in a sample of 23 undergraduates. A Fourier-based description of walking data served as the basis for the computation of linear classifiers and for the analysis of gait parameters. Results: Gait patterns associated with sadness and depression are characterized by reduced walking speed, arm swing, and vertical head movements. Moreover, depressed and sad walkers displayed larger lateral swaying movements of the upper body and a more slumped posture. Conclusion:The results of the present study indicate that a specific gait pattern characterizes individuals in dysphoric mood.

Background:In spite of many similarities in the psychopathology of anorexia nervosa (AN) and bulimia nervosa (BN), the 2 groups seem to differ in terms of body image disturbances. Therefore, the aim of the present study was to compare neuronal correlates of viewing photographs of one's own body and another woman's body in patients with these forms of eating disorders as well as controls. Methods: We performed functional magnetic resonance imaging while women with AN (n = 13), BN (n = 15) and healthy controls (n = 27) viewed 16 standardized pictures of their own body and another woman's body, taken while the participants were wearing a bikini. Results: When viewing their own body, participants with AN and BN showed reduced activity in the inferior parietal lobule compared with healthy women. In response to looking at another woman's body, participants with AN had higher amygdala activity than did those in the BN and control groups. Limitations: The generalizability of the results is limited by the small sample size. Conclusion: Our data suggest decreased attentional processes in AN and BN toward one's own body, possibly reflecting body-related avoidance behaviour. Enhanced limbic activity elicited by looking at another woman's body in participants with AN might be a neural correlate of stronger emotional activation and enhanced vigilance, possibly resulting from social comparison processes. Our study reveals hints about body image-associated alterations in brain activity, which seem to be more pronounced among women with AN than among those with BN.

Psychotherapy does not always follow a linear path. The present study explores the frequency of sudden gains and losses during the course of outpatient psychotherapy. The sample includes 1500 patients treated at three different outpatient centers. The patients were 57.4% female, and suffered primarily from anxiety and depressive disorders. Progress was measured by session reports. Significant sudden shifts in both directions were prevalent for 28.9% of the patients. Patients with early sudden gains showed the highest effect sizes and patients with sudden losses showed the smallest at the end of treatment. The therapeutic relationship was significantly better after the sudden gain sessions. Results suggest further investigation of the occurrence of sudden gains in relation to early response as well as further exploration of sudden losses during the course of treatment with respect to differential patterns of change and outcome.

Sample size tables, including varying sample size conditions, were constructed and study examples given. This study gives an insight into the potential size of the TE and provides researchers with a practical guide to aid the planning of future studies in this field.
