Connecting a health-focused self-concept with orthorexia nervosa symptoms via fear of losing control over eating unhealthy food and disgust for unhealthy food.

Purpose: Orthorexia nervosa (ON) involves a maladaptive preoccupation with healthy eating through strict dietary rules that negatively affect physical and mental health. Recent evidence suggests that ON symptoms may stem, in part, from having a health-focused self-concept (i.e.

Comparison of visual perceptual organization in schizophrenia and body dysmorphic disorder.

People with schizophrenia are impaired at organizing potentially ambiguous visual information into well-formed shape and object representations. This perceptual organization (PO) impairment has not been found in other psychiatric disorders. However, recent data on body dysmorphic disorder (BDD), suggest that BDD may also be characterized by reduced PO.

Mental contamination: the effects of imagined physical dirt and immoral behaviour.

There is a growing body of empirical support for Rachman's (1994, 2004, 2006) conceptualization of mental contamination. The aim of this study was to tease apart manipulations of imagined physical descriptions (i.e.

Mental contamination: the perpetrator effect.

In order to test the proposition that imagining carrying out an unacceptable non-consensual act can evoke contamination-related feelings in the perpetrator, 4 connected experiments were carried out involving male students. The effects of the experimental procedure were enhanced by the introduction of a theme of betrayal which boosted the feelings of contamination and urges to wash. The non-consensual scenarios were followed by substantial increases in negative emotions, notably shame, disgust and guilt, and these increases were boosted over successive enhancements of the procedure.

Analyses of mental contamination: Part II, individual differences.

Recent research on mental contamination (internal, psychological feelings of dirtiness) has focused primarily on examining the experimental variables necessary to provoke contamination-related thoughts, feelings and behaviour; yet, relatively little is known regarding the individual differences among participants' mental contamination responses to these situational and experimental characteristics. The purpose of this study was to determine whether variables associated with symptoms, beliefs and appraisals could predict the experience of mental contamination after an established provocation. Female undergraduate students (n = 70 from Part I of this study; Elliott & Radomsky, 2009), completed a series of questionnaires then listened to an audio recording and imagined that they were receiving a forced, non-consensual kiss from a man described as moral or immoral.

Analyses of mental contamination: Part I, experimental manipulations of morality.

The fear of contamination is thought to be comprised of two separate but related fears: those pertaining to physical and mental contamination. Previous research on mental contamination involved studies in which more than one independent variable was manipulated simultaneously. In particular, an immoral act (e.

Separating hoarding from OCD.

There is confusion about the status of excessive hoarding. In particular, there is an unresolved question about whether or not it is a manifestation of obsessive-compulsive disorder (OCD). There are some definite similarities between 'compulsive' hoarding and OCD, but they are outweighed by the differences between them.
