Background: Eating disorders have a high prevalence in young females and show high mortality rates. Difficulties with emotion regulation are associated to these disorders, with high levels of anger and aggression suppression playing a key-role. In clinical practice, emotional assessment is often performed by subjective measures. These self-report measures have received several critiques for this population, because of patients’ personality traits and social desirability in answering. Recently, a new objective instrument has been developed to use in addition to subjective measures of emotion regulation, called the Method of Stamp, Strike, Shout (MSSS). This instrument uses force production as a behavioral measure of anger and aggression regulation. This study examines the feasibility and first test results of the MSSS in a small clinical sample of patients with eating disorders. The aim is to examine the relation between the MSSS and anger coping style of patients in comparison to a matched control sample of healthy students. Method: The MSSS consists of three subtests, including stamping on a force plate, striking a punching bag instrumented with an accelerometer, and shouting into a microphone. Participants were asked to increase and decrease their force production, thereby producing a four-step force pyramid on each subtest. The method is developed as an addition to self-report measures. Anger coping style is assessed using the Self-Expression and Control Scale (SECS). When examining the feasibility of the measure in the clinical sample, both patients’ and researchers’ measurement experiences were evaluated. Overall, a critical analysis of measurement procedures, data analysis and outcome measures is performed to examine the feasibility and first associations between test results of the clinical and control sample. Results: Seven participants with eating disorders were included and compared to a sample of matched controls (n=21). Both patients’ and researchers’ experiences, procedures, and data analysis methods were positive or showed possibilities for improvements regarding, the feasibility of the measure. First, the anger coping styles of the groups were analyzed. As expected, patients scored higher on the SECS internalization of anger (AI) and AI was the preferred coping style of 6/7 patients. Visual inspection showed lower values of shout subtest for patients compared to controls. Both the MANCOVA and regression analysis showed that the shout subtest was most discriminative between groups. A significant interaction was found between group and coping style for the shout subtest in the repeated measures MANCOVA. With the regression analysis, AI-coping style was recognized as a significant negative predictor for the shout sum score. Overall, the stamp and strike subtests did not show significant results of either MANCOVA or regression analysis. At this time, there is insufficient evidence to relate the shape of the stamp and strike force pyramids to either group or anger coping style. Discussion: The measure appears feasible in a clinical sample of patients with eating disorders. However, several improvements are recommended to fit the clinical sample. Because of the small sample size and violated assumptions, no conclusions can be made on the initial analyses with the current sample. However, there appears to be a trend of the shout subtest’s ability to distinguish between groups or coping style, in line with previous test results in a student sample. The anger-performance relation in eating disorder patients is complex and should be carefully re-examined in a much larger sample with sufficient power, before conclusions can be made.
