Frontal Alpha Asymmetry As A Pathway To Behavioural Withdrawal In Depression: Research Findings And Issues, Emmanuel Jesulola, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Peter Wilson
Frontal Alpha Asymmetry As A Pathway To Behavioural Withdrawal In Depression: Research Findings And Issues, Emmanuel Jesulola, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Peter Wilson
Vicki Bitsika
Depression has been described as a process of behavioural withdrawal from overwhelming aversive stressors, and which manifests itself in the diagnostic symptomatology for Major Depressive Disorder (MDD). The underlying neurobiological pathways to that behavioural withdrawal are suggested to include greater activation in the right vs the left frontal lobes, described as frontal EEG asymmetry. However, despite a previous meta-analysis that provided overall support for this EEG asymmetry hypothesis, inconsistencies and several methodological confounds exist. The current review examines the literature on this issue, identifies inconsistencies in findings and discusses several key research issues that require addressing for this field to …
Measuring Individual Burden Of Illness For Depression Among Prostate Cancer Patients, Christopher Sharpley, Vicki Bitsika, David Christie
Measuring Individual Burden Of Illness For Depression Among Prostate Cancer Patients, Christopher Sharpley, Vicki Bitsika, David Christie
Vicki Bitsika
Objective: This study aims to develop and test three potential models of Individual Burden of Illness for Depression (IBI-D) in prostate cancer patients. Methods: Responses to three sets of scales measuring depressive symptoms, functional impairment, and quality of life satisfaction were collected from 191 prostate cancer patients and analysed via principal components analysis to obtain weightings for each of the scales within the three sets of measures. These weightings were then used to form IBI-D Indices, and these were then compared with depressive symptoms alone for their overlap. Results: Single-factor solutions were found for each of the three IBI-D models, …
Variability In Depressive Symptoms Of Cognitive Deficit And Cognitive Bias During The First 2 Years After Diagnosis In Australian Men With Prostate Cancer, Christopher Sharpley, Vicki Bitsika, David Christie
Variability In Depressive Symptoms Of Cognitive Deficit And Cognitive Bias During The First 2 Years After Diagnosis In Australian Men With Prostate Cancer, Christopher Sharpley, Vicki Bitsika, David Christie

The incidence and contribution to total depression of the depressive symptoms of cognitive deficit and cognitive bias in prostate cancer (PCa) patients were compared from cohorts sampled during the first 2 years after diagnosis. Survey data were collected from 394 patients with PCa, including background information, treatments, and disease status, plus total scores of depression and scores for subscales of the depressive symptoms of cognitive bias and cognitive deficit via the Zung Self-Rating Depression Scale. The sample was divided into eight 3-monthly time-since-diagnosis cohorts and according to depression severity. Mean scores for the depressive symptoms of cognitive deficit were significantly …
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
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 …
Help-Negation And Suicidal Ideation: The Role Of Depression, Anxiety And Hopelessness., Coralie J. Wilson
Help-Negation And Suicidal Ideation: The Role Of Depression, Anxiety And Hopelessness., Coralie J. Wilson

Help-negation is expressed behaviorally by the refusal or avoidance of available help and cognitively by the inverse relationship between self-reported symptoms of psychological distress and help-seeking intentions. The current study is part of a larger multi-cite research program developed and led by the first author. It examines the association between suicidal ideation and intentions to seek help from friends, family and professional mental health sources in a sample of 302 Australian university students. Participants were 77.5% female and aged from 18-25 years old, with 85.4% aged 21 years or younger. Higher levels of suicidal ideation were related to lower help-seeking …
Depressive Symptoms And Help-Seeking Intentions In Young People., Coralie J. Wilson
Depressive Symptoms And Help-Seeking Intentions In Young People., Coralie J. Wilson
Coralie J Wilson
Whether the help-negation effect as demonstrated for suicidal thoughts was also evident for depressive symptoms was investigated in three studies of young people from diverse urban areas. The studies comprised a large sample of younger high school students (years 7-10), a sample of older high school students (years 8-12), and first year university students. A self-report questionnaire that measured help-seeking intentions, prior help-seeking experiences, and depression was administered. Results revealed the strongest inverse association between level of depressive symptoms was with intentions to seek help from parents across all three samples. There was a consistent trend for students to report …
