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
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

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

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 …
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 …
Comorbidity Of Anxiety-Depression Among Australian University Students: Implications For Student Counsellors, Vicki Bitsika, Christopher Sharpley
Comorbidity Of Anxiety-Depression Among Australian University Students: Implications For Student Counsellors, Vicki Bitsika, Christopher Sharpley
Vicki Bitsika
The incidence, factor structure and scale item differences in anxiety-depression comorbidity were investigated in a sample of Australian university students defined according to the presence of anxiety and/or depression. The incidence of anxiety-depression comorbidity was over 32%, about four times that for anxiety or depression alone. Participants with comorbidity had significantly higher Selfrating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) total and factor scores than those with anxiety or depression alone. The major differences between the comorbid and unitary disordered subgroups were for self-disintegration and autonomic arousal. Comorbidity of anxiety and depression is a more serious disorder than either …
The Impact Of Students' 'Internally' Versus 'Externally' Oriented Coping Strategies Upon Anxiety And Depression: Implications For Counselling Processes, Vicki Bitsika, Christopher Sharpley, Aspasia Aroutzidis, Dimity Smith
The Impact Of Students' 'Internally' Versus 'Externally' Oriented Coping Strategies Upon Anxiety And Depression: Implications For Counselling Processes, Vicki Bitsika, Christopher Sharpley, Aspasia Aroutzidis, Dimity Smith
Vicki Bitsika
As a preliminary investigation of the implications for counselling practice of Purpose in Life (PIL), Search for Neotic Goals (SONG) and Conscientiousness (CON) as potential buffers against anxiety and depression among university student clients, 398 students from a university in eastern Australia completed measures of these constructs. Results indicated that, although having a clear PIL and being conscientious were negatively associated with anxiety and depression, SONG was positively linked with these disorders. More importantly for counselling processes, up to 10% of those students whose anxiety and depression would make them most likely to seek counselling showed inverse relationships between PIL, …
The Specific Environmental Antecedents Of Anxiety And Depression Among Australian University Students: Development Of The Effects Of University Study On Lifestyle Questionnaire, Vicki Bitsika, Christoper Sharpley, Leslie Hartley
The Specific Environmental Antecedents Of Anxiety And Depression Among Australian University Students: Development Of The Effects Of University Study On Lifestyle Questionnaire, Vicki Bitsika, Christoper Sharpley, Leslie Hartley

A 60-item scale of stressors that had been developed from interviews with 32 individual students was evaluated by administration to 402 students at an Australian university. As well as data that showed frequency of stressor occurrence to be a more powerful predictor of anxiety and depression than degree of discomfort that the stressor induced, psychometric data from this participant sample enabled refinement of the original scale by deleting several items, thus producing a 42-item scale for further investigation. Implications for use of the scale to identify the "causal" stressors which students experience and which lead to anxiety and depression, are …
Variability In Anxiety And Depression Over Time Following Diagnosis In Patients With Prostate Cancer, Christoper Sharpley, David Christie, Vicki Bitsika
Variability In Anxiety And Depression Over Time Following Diagnosis In Patients With Prostate Cancer, Christoper Sharpley, David Christie, Vicki Bitsika
Vicki Bitsika
To determine the presence and nature of variability in anxiety and depression in patients with prostate cancer (PCa) over 3 years following diagnosis, 442 patients with PCa completed standardized anxiety and depression inventories via survey between 1 and 36 months after receiving their initial diagnosis. Data were analyzed from a series of 3-month cohorts, and results indicated that total scores and incidence of clinically significant anxiety and depression varied over time, but that this variability was restricted to specific subfactors of anxiety and depression. Provision of effective psychological treatment to patients with PCa is discussed.
Incidence And Nature Of Anxiety-Depression Comorbidity In Prostate Cancer Patients, Christoper Sharpley, Vicki Bitsika, David Christie
Incidence And Nature Of Anxiety-Depression Comorbidity In Prostate Cancer Patients, Christoper Sharpley, Vicki Bitsika, David Christie
Vicki Bitsika
Background: The aim of this study was to measure the incidence of anxiety-depression comorbidity among a sample of prostate cancer (PCa) patients and to investigate the total score, factor score and scale item differences across subgroups defined according to the presence of anxiety and/or depression. Methods: 491 PCa patients who had received their initial diagnosis between 1 and 113 months previously completed a survey of background variables, as well as the Zung Self-Rating Anxiety and Depression Scales (SAS, SDS). Results: Incidence of anxiety-depression comorbidity was nearly 16%, and higher than that previously reported in other samples. Although the directional differences …
Gender Differences In Factor Scores Of Anxiety And Depression Among Australian University Students: Implications For Counselling Interventions, Vicki Bitsika, Christopher Sharpley, Therese Melhem
Gender Differences In Factor Scores Of Anxiety And Depression Among Australian University Students: Implications For Counselling Interventions, Vicki Bitsika, Christopher Sharpley, Therese Melhem
Vicki Bitsika
Anxiety and depression inventory scores from 200 male and female university students attending a private university in Australia were examined for their factor structure. Once established, the two sets of factors were tested for gender-based differences, revealing that females were more likely than males to report symptomatology associated with pain and fatigue, sleeping and digestive problems, psychomotor agitation, confusion, and pessimism. Implications for counsellors are discussed.
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 …
Psychological Distress Among Prostate Cancer Patients: Fact Or Fiction?, Christopher Sharpley, Vicki Bitsika, David Christie
Psychological Distress Among Prostate Cancer Patients: Fact Or Fiction?, Christopher Sharpley, Vicki Bitsika, David Christie
Vicki Bitsika
Although the detrimental effect upon psychological well-being of receiving a diagnosis of, or treatment for, cancer has been demonstrated across many different types of cancer, three recent reviews of the psychological health of prostate cancer patients have produced contradictory conclusions. In order to elucidate the reasons for these apparent different conclusions, each of these reviews is described, with principal methods and fi ndings summarised. Actual data, methodology used to select/reject research studies for inclusion in reviews, plus the validity of strict methodological culling of some research studies are discussed. Several extra studies and commentaries are also described, and a resolution …
