A comparative study of the vocational interests of adults with and without ADHD

06 May 2015 (has links)
M.A. (Clinical Psychology) / Although Attention-Deficit/Hyperactivity Disorder (ADHD) was once thought to occur exclusively in the course of childhood, remitting in adolescence, it is increasingly accepted as a valid diagnosis in adulthood, with DSM-5 providing diagnostic criteria adapted for adults. Symptoms of ADHD in adulthood can lead to impairment in the occupational and tertiary educational environments among others, and additionally can lead to individual differences in ability to perform certain occupational functions, as well as in the occupations to which an individual may be attracted. Adults with ADHD have been shown to differ significantly in personality from non-ADHD adults. The "goodness of fit" between personality and environment underlies much of the predominant understanding of occupational choice. In addition to impairment in the work environment, a lack of fit may exist between adults with ADHD and many features common to organisations. Despite this, along with acknowledgement of the influence of career choice on various factors, including success, emotional welfare and personal productivity, there is a lack of literature dealing specifically with career counselling in ADHD populations. In order to investigate the differences between adults with and without ADHD in a number of areas commonly assessed for career counselling and guidance purposes, an ADHD screening tool, the Adult ADHD Self-Report Scale (ASRS) was administered to a sample (n=60) of adults with and without ADHD. Participants were then assigned to ADHD and non-ADHD groups on the basis of ASRS scores in conjunction with diagnostic history, and assessed by means of the Self-directed Search Questionnaire (SDS), and the Basic Traits Inventory (BTI). Tests for between-group differences revealed significant differences on a small number of variables with the ADHD group scoring significantly higher on only the Enterprising type of the SDS. On the BTI, the ADHD group scored significantly higher on Extraversion, and significantly lower on Conscientiousness. The ADHD group also scored significantly higher on the Actions, Ideas, and Imagination facets of the BTI's Openness to Experience factor.

Mental contamination: a replication and extension of the "dirty kiss" experiment. / CUHK electronic theses & dissertations collection

January 2010 (has links)
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.

Pattern separation and frontal EEG change as markers for responsiveness to electroconvulsive therapy

Davis, Kathryn 12 July 2017 (has links)
There is still a great deal that is unknown about various depressive conditions, though it is a very common affliction and cause of disability throughout the world. Not only do the underlying mechanisms of various types of depression remain uncertain, but the mystery of how different treatment options work and who will respond to them also persists. The aim of this study was to identify potential non-invasive biomarkers, to predict responsiveness to electroconvulsive therapy. Two hypotheses were investigated in this study. The first was that patient improvement from baseline on the neurocognitive, computer based pattern separation task prior to the third ECT treatment will correlate with a clinical antidepressant response. The second was that increased prefrontal slowing relative to baseline will correlate with a decrease in depressive symptoms. As a first step to validate this approach, a healthy control group performed both the pattern separation and EEG tasks once per week over the course of three weeks. Patient participants completed both tasks before their first ECT treatment, prior to their third treatment, and prior to their last treatment. A spectral analysis of EEG data was then conducted. Results indicated good test-retest reliability for the pattern separation task and EEG measurements across all three trials in the healthy control group. Results from patient data are inconclusive, but indicates that there is a change from baseline to subsequent trials for at least the EEG measurements. However, a larger sample size is needed to determine this. The limited results from this small patient sample suggest that these measurements may have clinical value in refining ECT treatment, and merit further study.

Use of the Attention Deficit/Hyperactivity Disorder Symptoms Rating Scale with Preschool Children

Phillips, Penny LaDee 01 May 2000 (has links)
Attention deficit/hyperactivity disorder (ADHD) is a common disorder among children and is usually diagnosed during the school years, although symptoms must be present before age 7. As more children enter into preschool programs, there is great opportunity for early identification and treatment of behaviors related to ADHD. The earlier children with symptoms of ADHD are treated, the better their chances of having successful school experiences. Unfortunately, diagnosing ADHD during early childhood is difficult, in part because there is a lack of adequate assessment instruments designed for this age group. The instruments that are available generally do not focus specifically on ADHD symptomology. The ADHD-SRS, a rating scale specifically developed for ADHD assessment, was designed for school-age (K-12) children. The present research study investigated the psychometric properties of the ADHD-SRS with a preschool-aged sample. The participants were 414 preschool children who were rated by their teachers and/or parents using the ADHD-SRS. The results shed some light on normative levels of ADHD behaviors in preschool children. It was found that the ADHD-SRS has good psychometric characteristics (e.g., internal consistency, convergent/divergent validity) for this population. Teacher and parent concordance was moderate (.31), consistent with other research findings. Limitations, clinical implications, and directions for future research are addressed.

När hälsa blir ohälsa : En studie om Ortorexia Nervosa och två sorters självkänsla

Beijar Odh, Maria January 2013 (has links)
Ortorexia Nervosa (ON) är ett idag relativt okänt fenomen och detfinns skilda åsikter angående vilken typ av problem det är. Det finns desom menar på att det kan vara en ätstörning eller ett tvångssyndrom.Studien genomfördes med syfte att undersöka hur utbrett ON är hosträningsintresserade människor samt undersöka om bassjälvkänsla ochförvärvad självkänsla kunde relateras på olika sätt till graden av ONsamt se ifall kön och ålder har någon inverkan på detta.Undersökningen genomfördes med enkäter som mätte graden av ONoch självkänsla på 102 deltagare. Det visade sig att 33% av antaletdeltagare hade poäng över tröskelvärdet för ON. Studiens äldre ochyngre deltagare visade sig vara de som fick högst poäng på testet förON, dock hittades ingen skillnad beträffande kön. Inga signifikantasamband mellan ON och de två typerna av självkänsla kunde hittas.Idag är forskningen bristfällig inom ON och fler studier behövs.

Characteristics of Intimate Partner Homicide Perpetrators

Häggström, Erik, Petersson, Joakim January 2012 (has links)
Abstract Introduction. Approximately 88.000 cases of assault were reported to the Swedish police during 2010. Twenty-five percent of these cases were considered as violence against women. Intimate partner violence (IPV) is a worldwide issue and poses a major threat to women’s health. In Sweden, 17 women are killed each year by an intimate partner. This study aimed at increasing the knowledge of perpetrators of intimate partner homicide (IPH), in terms of type of mental disorder and type of deadly violence exerted. Method. A total of 49 forensic psychiatric investigations were obtained from the Swedish National Board of Forensic Medicine in Huddinge. Eighteen perpetrators of IPH were compared to 31 perpetrators of deadly violence in a non-intimate relationship. Comparisons were made by coding principal diagnoses as described in the forensic psychiatric investigations, and type of deadly violence exerted using the Cornell coding guide for violent incidents. Results. Perpetrators of IPH were, to a greater extent, diagnosed with a dysphoric or borderline personality disorder (BPD), whereas perpetrators of deadly violence in a non-intimate relationship were significantly more often diagnosed with an antisocial personality disorder (ASPD). Perpetrators of IPH used more deadly violence with reactive features, whereas perpetrators of deadly violence in a non-intimate relationship used significantly more deadly violence with instrumental features. Discussion. The results of this study are in agreement with previous research. In conclusion, perpetrators of IPH are more reactive in their deadly violence and less antisocial, in terms of being diagnosed with ASPD and previous convictions, compared to perpetrators of deadly violence in a non-intimate relationship. This may be helpful in terms of preventing future risk for IPV and IPH.
