Predicting the restrictive eating, exercise, and weight monitoring Compulsions of anorexia nervosa.
Eating and weight disorders : EWD, 2019Co-Authors: E. Caitlin Lloyd, Maria Øverås, Bas Verplanken, Anne M. HaaseAbstract:Compulsions surrounding restrictive eating, exercise, and weight monitoring are thought to maintain abnormal eating behaviour in individuals with anorexia nervosa (AN). This study aimed to determine if AN psychopathology and trait anxiety explain the presence of restrictive eating, exercise, and weight monitoring Compulsions in a mixed sample. Participants were 31 females with AN and 31 age and gender-matched healthy individuals (HC). Restrictive eating, exercise and weight monitoring Compulsion presence was compared between AN and HC groups. Multivariable poisson regression analyses, adjusted for diagnostic status, were conducted to assess the association of both AN psychopathology and trait anxiety with Compulsions across the mixed group. Individuals with AN endorsed a greater number of restrictive eating, exercise and weight monitoring Compulsions compared to HC. In adjusted poisson regression analyses neither AN psychopathology nor trait anxiety predicted Compulsion presence: incidence rate ratio (IRR) for AN psychopathology = 1.15 [95% CI 0.84, 1.57], p = 0.39; IRR for trait anxiety = 1.01 [95% CI 0.97, 1.06], p = 0.50. Greater presence of restrictive eating, exercise and weight monitoring Compulsions was reported by individuals with AN, supporting the conceptualisation of disorder behaviours as compulsive. The study was underpowered to robustly evaluate the association between predictors of interest and the Compulsions outcome, largely owing to the small sample size. Further investigation is required, ideally using methods able to identify causal and mediation effects. Level V, cross-sectional study.

Compulsion resistant anonymous communications
Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2006Co-Authors: J ClulowAbstract:We study the effect Compulsion attacks, through which an adversary can request a decryption or key from an honest node, have on the security of mix based anonymous communication systems. Some specific countermeasures are proposed that increase the cost of Compulsion attacks, detect that tracing is taking place and ultimately allow for some anonymity to be preserved even when all nodes are under Compulsion. Going beyond the case when a single message is traced, we also analyze the effect of multiple messages being traced and devise some techniques that could retain some anonymity. Our analysis highlights that we can reason about plausible deniability in terms of the information theoretic anonymity metrics. © Springer-Verlag Berlin Heidelberg 2005.
