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 …
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

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 …
Do Patient-Reported Androgen-Deprivation Therapy Side Effects Predict Anxiety And Depression Among Prostate Cancer Patients Undergoing Radiotherapy? Implications For Psychosocial Therapy Interventions, Christopher Sharpley, Vicki Bitsika, David Christie
Do Patient-Reported Androgen-Deprivation Therapy Side Effects Predict Anxiety And Depression Among Prostate Cancer Patients Undergoing Radiotherapy? Implications For Psychosocial Therapy Interventions, Christopher Sharpley, Vicki Bitsika, David Christie

Antiandrogen therapy (AAT) is a common adjunct treatment for prostate cancer (PCa) patients and has shown significant benefits to long-term outcomes from radiation or surgery. Although AAT has some adverse side effects and data from breast cancer patients indicate that such side effects from hormonal therapies may contribute to anxiety and depression and may also hinder AAT treatment compliance, this issue has not been investigated within a sample of PCa patients. This study explores the incidence of AAT side effects in a sample of PCa patients, the links between those side effects and anxiety and depression, the possible ways in …
Do Prostate Cancer Patients Suffer More From Depressed Mood Or Anhedonia?, Christopher Sharpley, Vicki Bitsika, David Christie
Do Prostate Cancer Patients Suffer More From Depressed Mood Or Anhedonia?, Christopher Sharpley, Vicki Bitsika, David Christie
Vicki Bitsika
Objective: This study aimed to compare the prevalence of depressed mood and anhedonia in a sample of men with prostate cancer (PCa) and to determine which of these key symptoms contributed most to the overall depressive status of that sample. Method: From Zung Self-rating Depression Scale (SDS) responses collected on 526 PCa patients, direct comparisons were made between the prevalence of the first two DSM-IV-TR symptoms of Major Depressive Episode. These symptoms were then tested for their predictive power on depression total score and Zung’s criteria for ‘clinically significant’ depression. Results: Mean scores for anhedonia were significantly higher than for …
Causal 'Mapping' Of Depression And Anxiety Among Prostate Cancer Patients: A Preliminary Interview Study, Christopher Sharpley, Vicki Bitsika, David Christie
Causal 'Mapping' Of Depression And Anxiety Among Prostate Cancer Patients: A Preliminary Interview Study, Christopher Sharpley, Vicki Bitsika, David Christie
Vicki Bitsika
Background: Men with prostate cancer experience elevated levels of anxiety and depression, with some previous data suggesting that this is due to loss of previously-available social and personal reinforcing pleasant activities and abilities. Little is currently known about the range of activities/abilities that these patients lose, leaving open the question of how to best target lifestyle changes designed to help them overcome these negative effects on their mental health. This study used personal interviews to gather details of the pattern of lost activities/abilities from a sample of men with prostate cancer so that a self-report questionnaire might be developed for …
Positive (But Not Negative) Punishment Predicts Anxiety And Depression Among Prostate Cancer Patients: An Exploration Of The Behaviour Analytic Model Of Depression, Vicki Bitsika, Christopher Sharpley, David Christie
Positive (But Not Negative) Punishment Predicts Anxiety And Depression Among Prostate Cancer Patients: An Exploration Of The Behaviour Analytic Model Of Depression, Vicki Bitsika, Christopher Sharpley, David Christie
Vicki Bitsika
The relative power of Positive and Negative Punishment as predictors of anxiety and depression was investigated within the gender-specific population of Prostate Cancer patients. As well as being a more powerful predictor of total test scores, Positive Punishment was also a stronger predictor of the presence of clinical levels of anxiety and depression. Examination of the particular Positive Punishment events that were significantly associated with clinical anxiety and depression showed considerable overlap, supporting the concept of a combined anxiety-depression disorder. Suggestions for behavioural interventions with this patient group are made.
Helping Prostate Cancer Patients Understand The Causes Of Anxiety And Depression: Comparing Cancer-Caused Vs Patient Response Events, Christopher Sharpley, Vicki Bitsika, David Christie
Helping Prostate Cancer Patients Understand The Causes Of Anxiety And Depression: Comparing Cancer-Caused Vs Patient Response Events, Christopher Sharpley, Vicki Bitsika, David Christie
Vicki Bitsika
Background: Prostate cancer (PCa) patients have elevated anxiety and depression, often showing impairments in decision-making and weakened relationships with their partner and family. Although treatment for these psychological side-effects of PCa is strongly recommended, relatively little is known of the causal processes underlying them. This study compared cancer-based lifestyle changes vs patient behavioural responses to cancer as predictors of anxiety and depression among PCa patients. Methods: PCa patients (381) were surveyed for their responses to standardised anxiety and depression questionnaires, plus a questionnaire designed to assess the kinds of lifestyle changes that had occurred to them and their responses to …
