The impact of violent video-games on cognition, affect and personality

This research investigated the impact of playing violent videogames. Aggressive or anxious responses were most likely: when the player perceived the violence in the games to be extreme, when the player experienced a heightened sense of becoming 'absorbed' into the game, and during a relatively brief exposure to the game. The portfolio explores the use of manualised interventions in psychology research and practice. Four illustrative case studies regarding the efficacy and effectiveness of adapting manualised interventions for clients with chronic health conditions are presented.

Application of the psychological contract to occupational safety

Psychological contracts were applied to occupational safety. A psychological contract of safety measure was developed and validated, and a model of safety developed to investigate breach and fulfilment of the psychological contract of safety. Findings suggest that the psychological contract of safety impacts safety attitudes and safety behaviour.

Body image in adolescent girls

This study investigated the Tripartite Influence Model of body image and eating disturbance in adolescent females. The model was found to be a satisfactory representation of the social, cultural and individual factors proposed to promote body dissatisfaction, dieting and bulimic behaviours in 14 to 18 year old girls. The portfolio presents four case situations in which the specialist knowledge of a clinical psychologist has shown to be beneficial to pediatric patients, their families, and medical staff at a major metropolitan hospital.

Psychological impact of DAFNE training in adults with Type 1 diabetes

This thesis investigated the psychological impact of an education intervention, Dose Adjustment for Normal Eating (DAFNE), in adults with type 1 diabetes. The results demonstrated that the education programme improved participants' subjective wellbeing, self-efficacy and reduced diabetes-related distress compared to a comparison group that engaged in usual care. The portfolio examined the use of mindfulness-based strategies, in particular Acceptance and Commitment Therapy (ACT) in four case studies which illustrated that the impact of the therapy is directly related to the the willingness of the client to engage in the practices.

PTSD symptomatology in children and adolescents : treatment development and evaluation

This thesis developed, implemented and evaluated a cognitive-behavioural group treatment programme for children and adolescents experiencing symptoms of PTSD (Post-traumatic stress disorder). Results of the study indicate that symptoms of sleep disturbance and flashbacks, reduced markedly in the participants, providing a useful tool in reducing synptoms experiences by individuals exposed to trauma. The Professional portfolio presents four case studies that demonstrate the clinical application of the affect of chronic illness on the psychological adjustment of the sufferer and their families.

Body image and psychological, social, and sexual functioning

This thesis examined the nature of the body image construct, as well as the relationships between body image and self-esteem, depression, anxiety, and social functioning. Body image was demonstrated to play an important role in the everyday lives of adolescent boys and girls, and men and women throughout adulthood.

Enhancing juror decision-making through provision of transcripts

This thesis explored how much evidence jurors remember when instructed to reach a verdict. Results indicated that jurors required to rely on memory recalled significantly less evidence than jurors provided with access to the court transcript and were less confident than aided jurors that they had returned the 'right' verdict. The portfolio explored a possible association between chronic childhood challenging behaviours and later offending behaviour in individuals with intellectual disability. Includes four clinical case studies. The importance of early intervention is illustrated.

Psychological deficits and abundances among domestically violent offenders and non-offenders

The thesis compared domestically violent men and non-offenders on a number of psychological constructs. The results indicated that, with the exception of attitudes towards women, there were no significant differences between the groups. The thesis examined practical implications of the results for the assessment and treatment of domestically violent offenders. The professional portfolio examines, in four case studies, the purported link between childhood abuse and subsequent maladjustment in the adult.

The psychological and relationship impact of erectile dysfunction

This thesis demonstrated that Australian men with erectile dysfunction (ED) experience poorer levels of masculinity, self-esteem, quality of life, sexual satisfaction and relationship satisfaction than do men without ED. The implications of these findings for the current medical approach to treating this sexual dysfunction were discussed. The portfolio explores grief following elective abortion and reflects on how grief responses may present in post-abortion counselling. The potential utility of grief therapy to this counselling is demonstrated in four case studies.

The neuroanatomical correlates of subjective wellbeing following head injury

The thesis found results supporting the involvement of the Right Frontal area of the brain in the subjective wellbeing (SWB) of individuals. Additional results suggested SWB is dependent upon Core Affect, itself dependent upon the Right Parietal area of the brain. These results provide evidence that SWB and Core Affect are based upon a neurological substrate. The portfolio investigated the association between chronic medical conditions and anxiety disorders, and how the occurence of anxiety issues can affect overall psychological adjustment to illness.

A hypothesised model of disordered eating in overweight women

This thesis found that predicted risk factors for disordered eating were similar for overweight and non-overweight women. However, overweight women reported more stigmatisation and body shame, had a higher risk for developing an eating disorder, and were twice as likely to be diagnosed with a subclinical/clinical eating disorder than non-overweight women. The portfolio presents four case studies demonstrating the considerations and challenges of psychologically assessing and treating individuals with chronic health conditions.

Psychological study of consumer novelty seeking and mass media consumption

The thesis integrates theory from psychology and marketing, finding that those with an innate desire to seek out information on new products / brands are motivated to do so by aspects of regulatory focus, needs for uniqueness, and their susceptibility to interpersonal influence. In turn, these people consume more media and have higher information exposure.

Adults with arthritic conditions and care-seeking in an attachment framework

This thesis investigated the role of care-seeking amongst adults with arthritis, using an attachment framework to help explain the inconsistent results of previous studies in regard to psychological adjustment to a chronic illness. The results highlight the importance of attachment processes in partially influencing care-seeking and coping strategies that shape psychological adjustment. The portfolio addresses the frequent co-occurence of depression with chronic medical disorders. This impacts the ability for chronic, medically ill adults to engage in self-management strategies. Four case studies are presented.

Coping with unemployment : impact on psychological health

Investigates alternative solutions to promoting psychological health during unemployment. Unemployed people who engage in meaningful leisure activity, who had a pro-active approach to coping, and utilised more social support networks, demonstrated better psychological adjustment. Suggests that such activities may contribute to re-employment.
