ABSTRACT
OBJECTIVE: Patients with anorexia nervosa (AN) often show difficulties in the perception, expression, and regulation of emotions and a strong avoidance of aversive feelings. According to psychobiological models, dietary restraint and accompanying weight loss may serve as a maladaptive mechanism of emotion regulation by attenuating aversive emotional states in AN, thereby contributing to the maintenance of the disorder. METHOD: Twenty-seven women with AN and 26 age-matched healthy women were shown short film-clips to elicit fear, sadness, amusement, and neutral emotional states. Eyeblink startle response was measured by electromyography in reaction to startle-eliciting acoustic stimuli presented 12 times binaurally during each film-clip. RESULTS: As compared to healthy controls, patients with AN showed a blunted startle response to the fear- but not to the sadness-eliciting stimulus. DISCUSSION: The findings support the assumption that underweight is associated with attenuated emotional reactivity to fear-eliciting material in AN. This is in line with the hypothesis that starvation and low body weight constitute a maladaptive mechanism of emotion regulation in AN, contributing to the maintenance of the disorder.

OBJECTIVE: Since previous meta-analyses of psychiatric-psychosomatic rehabilitation only rarely included studies from Austrian rehabilitation clinics a systematic review with meta-analysis of previously available evaluation results from Austrian rehabilitation clinics should be conducted. METHODS: A systematic literature search in several data bases (Psyndex, PsycInfo, MEDLINE, Pubmed) and additional manual search was conducted. Evaluation results from the most commonly used assessment instruments (SCL-90/BSI, BDI, WHOQOL-BREF, GAF) were extracted from the studies included and subsequently a meta-analysis was calculated with the extracted data (pre-post comparison). RESULTS: 12 publications with 9 studies from 6 different Austrian rehabilitation clinics could be included in the meta-analysis, with a total of 9329 patients. Results show a significant improvement from pre- to post assessment in the medium effect size range, with a Hedges' g of 0.53 (95%-confidence interval [0.45;0.60]) for improvement in global symptom severity, a Hedges' g of 0.59 (95%-confidence interval [0.54;0.63]) for improvement in subjective quality of life and a Hedges' g of 1.00 (95%-confidence interval [0.83;1.18]) for improvement in global functioning. The effects are robust and there is no evidence for distortion or publication bias. CONCLUSIONS: On average medium effect sizes have been previously achieved with psychiatric-psychosomatic rehabilitation in Austrian rehabilitation clinics. This is comparable with the previous results of rehabilitation clinics in Germany. However, since only one controlled study is available thus far it can not be ruled out that the effects in comparison to no rehabilitation might turn out smaller. Thus, in the future increasingly controlled studies should be conducted and the quality of conducted studies should be improved.

BACKGROUND: In the course of development, children show increased insight and understanding of emotions-both of their own emotions and those of others. However, little is known about the efficacy of training programs aimed at improving children's understanding of emotion. OBJECTIVES: To conduct an effect size analysis of trainings aimed at three aspects of emotion understanding: external aspects (i.e., the recognition of emotional expressions, understanding external causes of emotion, understanding the influence of reminders on present emotions); mental aspects (i.e., understanding desire-based emotions, understanding belief-based emotions, understanding hidden emotions); and reflective aspects (i.e., understanding the regulation of an emotion, understanding mixed emotions, understanding moral emotions). DATA SOURCES: A literature search was conducted using PubMed, PsycInfo, the Cochrane Library, and manual searches. REVIEW METHODS: The search identified 19 studies or experiments including a total of 749 children with an average age of 86 months (S.D.=30.71) from seven different countries. RESULTS: Emotion understanding training procedures are effective for improving external (Hedge's g = 0.62), mental (Hedge's g = 0.31), and reflective (Hedge's g = 0.64) aspects of emotion understanding. These effect sizes were robust and generally unrelated to the number and lengths of training sessions, length of the training period, year of publication, and sample type. However, training setting and social setting moderated the effect of emotion understanding training on the understanding of external aspects of emotion. For the length of training session and social setting, we observed significant moderator effects of training on reflective aspects of emotion. CONCLUSION: Emotion understanding training may be a promising tool for both preventive intervention and the psychotherapeutic process. However, more well-controlled studies are needed.
