The Self-Mutilative Nature of Severe Onychophagia: A Comparison with Self-Cutting

Severe morbid onychophagia: the classification as self-mutilation and a proposed model of maintenance

“…Such research is essential to improve the efficacy of treatment techniques and promote better understanding of individuals who self‐mutilate in this manner. An investigation of the psychophysiological responses associated with imaged nailbiting behaviour in comparison with imaged self‐mutilative behaviour has in fact been conducted [79].…”

Emotion regulation in pathological skin picking: Findings from a non-treatment seeking sample

“…Muehlenkamp et al, 2009) or by measuring physiological activity during guided imagery of skin picking (e.g. Wells, Haines, Williams, & Brain, 1999).…”

Psychophysiological and Psychological Correlates of Dissociation in a Case of Dissociative Identity Disorder

“…A scoring period of 30 seconds was extracted from each stage of each script. This scoring method has been successfully used elsewhere (e.g., Brain et al, 1998;Haines et al, 1995Haines et al, , 1998Wells et al, 1999). Mean heart rate from each scoring period was calculated.…”

“…Personalized guided imagery, where the individual is guided in a structured way through a memory of an actual event, has been demonstrated to result in accurate and interpretable responses that mimic the responses that occurred at the time of the event (Brain, Haines, & Williams, 1998;Haines, Josephs, Williams, & Wells, 1999;Haines, Williams, Brain, & Wilson, 1995;Pitman et al, 2001;Shin et al, 2000;Wells, Haines, Williams, & Brain, 1999). In addition, by dividing the event in question into stages and presenting the imagery scripts in this way (e.g., Brain et al, 1998;Haines et al, 1995Haines et al, , 1998Wells et al, 1999), the development of a response such as dissociation can be considered and the processes associated with the response examined.…”
