Measuring Depression In Prostate Cancer Patients: Does The Scale Used Make A Difference?, Christopher Sharpley, Vicki Bitsika, David Christie, Myra Hunter Nov 2015

Measuring Depression In Prostate Cancer Patients: Does The Scale Used Make A Difference?, Christopher Sharpley, Vicki Bitsika, David Christie, Myra Hunter

Vicki Bitsika

This study investigated differences in the scores, relative severity and major depressive disorder (MDD) and subsyndromal depression status from three standardised self-report scales for depression in prostate cancer (PCa) patients. The Hospital Anxiety and Depression Scale Depression subscale (HADS-D), the Self-rating Depression Scale (SDS) and the Patient Health Questionnaire (PHQ-9) for depression were administered to a sample of 138 PCa patients via mail-out self-reports in Queensland, Australia during May 2014. Despite significant correlations between the total scores from the three scales, severity classification differed across the three scales and there was evidence of considerable underestimation of depression by the HADS-D …


Differences In The Prevalence, Severity And Symptom Profiles Of Depression In Boys And Adolescents With An Autism Spectrum Disorder Versus Normally Developing Controls, Vicki Bitsika, Christopher Sharpley Oct 2015

Differences In The Prevalence, Severity And Symptom Profiles Of Depression In Boys And Adolescents With An Autism Spectrum Disorder Versus Normally Developing Controls, Vicki Bitsika, Christopher Sharpley

Vicki Bitsika

The prevalence, severity and symptom profiles for major depressive disorder (MDD) were compared in samples of boys and adolescents with and without an autism spectrum disorder (ASD). Self-reports were obtained on the Depression subscale of the Child and Adolescent Symptoms Inventory (CASI-D) with 70 ASD and 50 non-ASD male participants between the ages of 8 and 18 from Queensland, Australia who were matched for age and IQ. Results indicated that the ASD participants had significantly higher total CASI-D scores, a greater proportion of participants who qualified for a diagnosis of MDD, and over 50% higher scores for 8 of the …


Eight-Month Test-Retest Agreement In Morning Salivary Cortisol, Self- And Parent-Rated Anxiety In Boys With An Autism Spectrum Disorder, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Nicholas Andronicos Oct 2015

Eight-Month Test-Retest Agreement In Morning Salivary Cortisol, Self- And Parent-Rated Anxiety In Boys With An Autism Spectrum Disorder, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

The agreement over time in morning salivary cortisol concentrations and also self- and parent-rated anxiety was investigated in a sample of 16 boys with an ASD. Cortisol and anxiety data were collected eight months apart. Results indicated that there were significant correlations between each pair of measures from the two occasions, suggesting that cortisol concentrations and anxiety did not vary much at all over that time, challenging the assumption that cortisol needs to be measured over multiple days to obtain reliable data from children with an ASD. Implications for research into the ways these children respond to chronic stressors are …


What Is More Likely To Predict Prejudicial Attitudes Towards Overweight Individuals: Gender, Locus Of Control, Or Social Dominance Orientation?, Joanna Kelly, Peta Stapleton Sep 2015

What Is More Likely To Predict Prejudicial Attitudes Towards Overweight Individuals: Gender, Locus Of Control, Or Social Dominance Orientation?, Joanna Kelly, Peta Stapleton

Peta B. Stapleton

As obesity has become an important healthcare issue, more research has revealed a pervasive bias against overweight individuals. Individuals are often perceived to be in control of their own weight, and therefore, if one is overweight they are considered lazy, lacking in self-control, and non-compliant (Rukavina & Li, 2011; Stapleton, 2013). Although obesity rates are rising across countries, there has been no reduction in the negative attitudes and prejudices expressed towards the overweight (Stapleton, 2013). This study was conducted to assess the effects that Health Locus of Control (HLOC), Social Dominance Orientation (SDO) (Pratto, Sidanius, Stallworth & Malle, 1994), and …


Use Of Complementary Therapies By Registered Psychologists: An International Study, Peta Stapleton, Hannah Chatwin, Emma Boucher, Sue Crebbin, Sandra Scott, Dean Smith, Gail Purkis Aug 2015

Use Of Complementary Therapies By Registered Psychologists: An International Study, Peta Stapleton, Hannah Chatwin, Emma Boucher, Sue Crebbin, Sandra Scott, Dean Smith, Gail Purkis

Peta B. Stapleton

Complementary and alternative medicine (CAM) is a category of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medicine. However, the use of CAM by lay people is increasing worldwide. This study investigated the utilization pattern of CAM among registered psychologists, and level of training in delivering a CAM service. Psychologists (N = 193) participated from Australia, the United States, the United Kingdom, and New Zealand. Almost all (99.6%) respondents reported using at least 1 CAM service in the past, and 64.2% indicate they were trained to deliver at least 1 area …


Dysfunctional Eating In An Australian Community Sample: The Role Of Emotion Regulation, Impulsivity, And Reward And Punishment Sensitivity, Peta Stapleton, Melissa Whitehead Aug 2015

Dysfunctional Eating In An Australian Community Sample: The Role Of Emotion Regulation, Impulsivity, And Reward And Punishment Sensitivity, Peta Stapleton, Melissa Whitehead

Peta B. Stapleton

This study aimed to examine the role of emotion regulation and reinforcement sensitivity in dysfunctional eating behaviours. Two hundred twenty-eight adults from the Australian community completed self-report inventories assessing the variables. Dysfunctional restrained eaters differed from those who did not engage in restrained eating in terms of their emotion regulation, impulsivity, and sensitivity to reward. Difficulties in emotion regulation, low impulsivity, and sensitivity to reward predicted engagement in restrained eating. Emotional eaters significantly differed from those who did not engage in dysfunctional levels of emotional eating in terms of their emotion regulation, impulsivity, and sensitivity towards reward, and difficulties in …


Researching Depression In Prostate Cancer Patients: Factors, Timing, And Measures., Christopher Sharpley, Vicki Bitsika, David Christie, James Denham, Gillian Duchesne, Jeremy Couper Aug 2015

Researching Depression In Prostate Cancer Patients: Factors, Timing, And Measures., Christopher Sharpley, Vicki Bitsika, David Christie, James Denham, Gillian Duchesne, Jeremy Couper

Vicki Bitsika

Background: Due to the pressing need to understand the causal and associative factors of depression among prostate cancer (PCa) patients, a comprehensive research protocol for investigating depression in prostate cancer patients is suggested as a way of furthering the collection of data in consistent and informative ways. Methods: A detailed review of a range of predictors of, and buffers against, depression, plus methods of assessing depressive symptomatology and optimum time to collect data were used to develop a model for a comprehensive research protocol. Results: A model protocol is described that includes socioeconomic, genetic, endocrinal, immunological, physiological, psychological, relationship, and …


Caffeine Use And Alexithymia In University Students, Michael Lyvers, Natalija Duric, Fred Thorberg Aug 2015

Caffeine Use And Alexithymia In University Students, Michael Lyvers, Natalija Duric, Fred Thorberg

Mike Lyvers

Alexithymia refers to difficulties with identifying, describing, and regulating one’s own emotions. This trait dimension has been linked to risky or harmful use of alcohol and illicit drugs; however, the most widely used psychoactive drug in the world, caffeine, has not been examined previously in relation to alexithymia. The present study assessed 106 male and female university students aged 18-30 years on their caffeine use in relation to several traits, including alexithymia. The 18 participants defined as alexithymic based on their Toronto Alexithymia Scale (TAS-20) scores reported consuming nearly twice as much caffeine per day as did non-alexithymic or borderline …


Educating Medical Students About Anorexia Nervosa: A Potential Method For Reducing The Volitional Stigma Associated With The Disorder, Amy Bannatyne, Peta Stapleton Aug 2015

Educating Medical Students About Anorexia Nervosa: A Potential Method For Reducing The Volitional Stigma Associated With The Disorder, Amy Bannatyne, Peta Stapleton

Peta B. Stapleton

It is frequently reported that clinicians across a range of professional disciplines experience strong negative reactions toward patients with anorexia nervosa (AN). The present study aimed to develop, evaluate, and compare the effectiveness of two different educational programs, based on an etiological framing model. Participants were medical students (N = 41) from an Australian University, who were randomly assigned to one of three conditions (biogenetic intervention vs. multifactorial intervention vs. control). Outcome attitudinal/stigma data were collected preand post-intervention, and at 8 weeks follow-up. Results indicated intervention participations exhibited significantly lower volitional stigma scores compared to the control group, who exhibited …


Body Dissatisfaction And Surveillance, Exercise Frequency, Depression And Self-Esteem In A University Population, Peta Stapleton, Natalie Dzodz Aug 2015

Body Dissatisfaction And Surveillance, Exercise Frequency, Depression And Self-Esteem In A University Population, Peta Stapleton, Natalie Dzodz

Peta B. Stapleton

The purpose of the present study was to explore the relationship between body dissatisfaction and body surveillance, exercise frequency, depression and self-esteem in 121 university students from various Australian tertiary institutions aged between 17 to 45 years old population. This study also aimed to observe gender differences in the experience of body dissatisfaction. Inconsistent with previous research and the present hypothesis, no significant relationship was found between body dissatisfaction and exercise frequency or body surveillance. However, a significant relationship was found between body dissatisfaction and depression, as well as with self-esteem. Gender was also found to significantly predict body dissatisfaction, …


Differences In Major Depressive Disorder And Generalised Anxiety Disorder Symptomatology Between Prostate Cancer Patients Receiving Hormone Therapy And Those Who Are Not, Christopher Sharpley, Vicki Bitsika, Addie Wootten, David Christie Jul 2015

Differences In Major Depressive Disorder And Generalised Anxiety Disorder Symptomatology Between Prostate Cancer Patients Receiving Hormone Therapy And Those Who Are Not, Christopher Sharpley, Vicki Bitsika, Addie Wootten, David Christie

Vicki Bitsika

Objective: The aim of this study is to explore the associations between hormone treatment variables and depression, and the nature of depression in prostate cancer (PCa) patients by comparing the severity and symptom profile of anxiety and depression in men who were currently receiving hormone therapy (HT) versus those who were not. Method: Self-reports of anxiety and depression on standardized scales of GAD and major depressive disorder (MDD) were collected from 156 PCa patients across two recruitment sites in Australia. Patients who were currently receiving HT were compared with patients not receiving HT for their severity and symptom profiles on …


Variation In The Profile Of Anxiety Disorders In Boys With An Asd According To Method And Source Of Assessment, Vicki Bitsika, Christopher Sharpley Jul 2015

Variation In The Profile Of Anxiety Disorders In Boys With An Asd According To Method And Source Of Assessment, Vicki Bitsika, Christopher Sharpley

Vicki Bitsika

To determine any variation that might occur due to the type of assessment and source used to assess them, the prevalence of 7 anxiety disorders were investigated in a sample of 140 boys with an Autism spectrum disorder (ASD) and 50 non-ASD (NASD) boys via the Child and Adolescent Symptom Inventory and the KIDSCID Clinical Interview. Boys with an ASD were significantly more anxious than their NASD peers. Data collected from the boys with an ASD themselves showed differences in the severity and diagnostic criterion of anxiety disorders to data collected from the boys’ parents. There were age-related variations to …


Hypothalamus–Pituitary–Adrenal Axis Daily Fluctuation, Anxiety And Age Interact To Predict Cortisol Concentrations In Boys With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Nicholas Andronicos, Linda Agnew Jun 2015

Hypothalamus–Pituitary–Adrenal Axis Daily Fluctuation, Anxiety And Age Interact To Predict Cortisol Concentrations In Boys With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Nicholas Andronicos, Linda Agnew

Vicki Bitsika

There is considerable evidence of a confound between symptoms of generalised anxiety disorder (GAD) and autism spectrum disorder (ASD) in children who have an ASD. Although there have been several attempts to describe how these two disorders overlap and interact to influence the assessment and diagnosis of children with an ASD, principally by reference to cortisol assayed from these children's saliva, the overall evidence is inconsistent. Because previous models of these relationships have focused upon cortisol and GAD to the exclusion of age, diurnal fluctuation in the HPA axis and the source of GAD data, these variables were examined in …


Assessing Stress At Work Across Occupations And Cultures Using The Occupational Stress Inventory Revised, Richard Hicks, Ali Sa Banci, Mark Bahr Apr 2015

Assessing Stress At Work Across Occupations And Cultures Using The Occupational Stress Inventory Revised, Richard Hicks, Ali Sa Banci, Mark Bahr

Richard Hicks

Workplace stress is common across occupations and across nations. Culture is thought to impact on stress levels including what are common stressors, how the stress is experienced and what coping mechanisms or resources are used. However, there has been limited research examining these differences or supposed differences across cultures, and none that seem to have used a direct comparison across one professional area using the same extensive and validated questionnaire. One questionnaire that has potential for such direct comparison is the Occupational Stress Inventory-Revised (OSI-R: Osipow, 1999) which assesses three main dimensions related to stress: “occupational roles” (stressors), “personal strain” …
