Research into the phenomenon of compulsive hoarding has only been conducted during the last twenty years. To date, no studies have been done that examine the impacts of compulsive hoarding on young and grown children. The purpose of this qualitative study was to explore what the positive and negative impacts on children or adult children are. Twelve women, each identifying themselves as an adult child of a compulsive hoarder completed a qualitative questionnaire via email. Participants were recruited through membership in the internet support group, “children of hoarders”. All participants identified their mother as the compulsive hoarder. Three distinct themes emerged over three distinct time periods. The first time period begins with early childhood and continues through adolescence. The second begins with the time they first moved away from home. The third starts with the end of the second and continues through to whatever age they are today. The first theme's focus was the participants' feelings as associated with their mother's hoarding. The second theme dealt with a need to understand what “normal” is. The third theme was the means they use/used to cope with the situation. Clinical implications include support for using systems theory, ambiguous loss and attachment frameworks. This study also provides valuable information relevant to participants need to normalize their experiences. / Master of Science

This study was designed to explore the nature of compulsive buying behavior with respect to self esteem and money attitude variables. Conjointly, a newly developed screening device, the Compulsive Buying Scale, was used to test its ability to discern compulsive buying tendencies amongst consumers. Comparison was made with participating members of intact compulsive buying help groups and "normal" consumers. Compulsive buyers were found to significantly differ from normal consumers on variables tested. Compulsive buyers were found to have lower self esteem with money attitudes reflecting obsession with money and its perceived power and prestige. Likewise, compulsive buyers differed significantly on the Compulsive Buying Scale adding support to the validity of the scale.

Discussion: This study aims at expanding the understanding of mental contamination. First, the dirty kiss experiment is independently replicated in a Chinese population. Second, contact contamination and mental contamination are found to be separable and do not interact with each other. This underscores the independence of the two forms of contamination. Third, betrayal is shown to evoke mental contamination. Discussion has been made on the potential link between psychological violation, morality and mental contamination. / Mental contamination, an important phenomenon in OCD, refers to a sense of dirtiness without any contact with objectively dirty contaminant. However, the concept of mental contamination has not been thoroughly researched and there is an impending need for a psychological model to explain the phenomenon. / Method: Participants were assessed on questionnaires after imagining a non-consensual kiss or betrayal. / Objectives: The overall goal of this study is to enhance our understanding about mental contamination. Based on an experimental paradigm developed by Fairbrother, Newth, and Rachman (2005), three experiments are designed. The first experiment aims at replicating the results of the original study in local Chinese women. The second experiment examines the relationship between contact and mental contamination. The third experiment investigates the presence of mental contamination in persons experiencing betrayal. / Results: In Experiment 1, with an imagined non-consensual kiss, feeling of dirtiness, urge to wash and negative emotions were reproduced. In Experiment 2, it illustrated that either kissing a physically dirty looking man or being kissed non-consensually would experience stronger feeling of dirtiness, urge to wash and negative emotions. The last experiment showed that an imagined betrayal, a form of psychological violation, also induced a feeling of dirtiness, washing urge and negative emotions as with an imagined non-consensual kiss. / Three different pools of adult female participants were recruited for each experiment. In Experiment 1, 72 participants were recruited and randomly assigned to either a consensual kiss or a non-consensual kiss condition. In Experiment 2, 122 participants were recruited and randomly assigned to one of the four conditions. In Experiment 3, a total of 64 participants were recruited and randomly assigned to either non-betrayal or betrayal condition. / Kwok, Pui Ling Amy. / Adviser: Patrick Leung. / Source: Dissertation Abstracts International, Volume: 73-01, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 166-177). / Electronic reproduction.

Obsessive-Compulsive Disorder (OCD) is characterised by intrusions into conscious thinking by repetitive, personally abhorrent, absurd and alien thoughts (obsessions) which lead to endless repetitive acts or rehearsal of irrational and sometimes bizarre mental and behavioural rituals (compulsions). Although a number of clinical constructs have been proposed to have a causal influence on OC symptoms, extremely little research exists examining how these constructs are related to each other and, further, how the relationships between these constructs influences each constructs relationship with OC symptoms (e.g. does a given construct have an independent role in influencing OC symptoms or is the constructs influence on OC symptoms being mediated by its influence on another intervening construct or constructs?). In the current thesis, the relationships between 5 clinical constructs were examined, as well as how the pattern of these relationships may affect each constructs influence on OC symptoms. A large questionnaire study suggested that the five constructs are best seen as separate constructs rather than indicators of one underlying construct. Separate experimental studies in which all 5 constructs were manipulated individually suggest that whilst inflated responsibility, intolerance of uncertainty and negative mood, respectively, all causally influence every other construct focused on in this thesis, not just right experiences and as many as can stop rules, respectively, do not casually influence any other construct. Subsequent regression analyses suggest that whilst some constructs directly influence OC symptoms, other constructs influence on OC symptoms are mediated by intervening constructs in the final model, whilst some constructs have little to no influence on OC symptoms when the influence of other constructs in the final model are taken into account. Implications of these findings for existing models of OCD, for studies examining the relationship between multiple constructs and OC symptoms and for the treatment of OCD are discussed.

Trichotillomania (TTM) is currently classified as an impulse disorder in the DSM-IV, but there is a growing consensus amongst researchers that trichotillomania should be placed on the putative QCD-related disorders spectrum. QCD and TTM have been compared in many fields including neurobiology, phenomenology and epidemiology. Studies of cognition in QCD and TTM typically focus on automatic thoughts and underlying assumptions and there is a paucity of research into enduring cognitive structures, or schemas, associated with the two disorders. This thesis reviews the available evidence regarding the relationship between QCD and TTM. The Young Schema Questionnaire (YSQ) was used to measure 15 maladaptive schemas in 96 QCD patients, 34 TTM patients, and 94 controls. In the comparison between QCD and TTM it was found that depression has a major impact on the profile of schemas in QCD. When controlling for depression a few differences in schema profile were found between QCD and TTM, though the schema enmeshment emerged as significant in both disorders. These findings are discussed in the light of the debate around the classification of trichotillomania in the psychiatric nomenclature. / Thesis (M.A.)-University of Natal, Pietermaritzburg, 2003.
