Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant
Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant
Colleen S. Conley
This research investigated whether exposure to peer stress serves as one pathway through which pubertal development contributes to depression over time, differentially for girls and boys. Youth (N = 149; 9.6–14.8 years) and their caregivers provided information at two waves, 1 year apart, on puberty (Wave 1), peer stress (occurring between Waves 1 and 2), and depression (Waves 1 and 2). Structural equation modeling analyses examined sex differences in the extent to which peer stress mediated the impact of pubertal status and timing on subsequent depression (i.e., tests of moderated mediation). Significant sex-moderated mediation was found for both pubertal status …

Gene X Environment Effects Of Serotonin Transporter, Dopamine Receptor D4, And Monoamine Oxidase A Genes With Contextual And Parenting Risk Factors On Symptoms Of Oppositional Defiant Disorder, Anxiety, And Depression In A Community Sample Of 4-Year-Old Children, John Lavigne, Laura Herzing, Edwin Cook, Susan Lebailly, Karen Gouze, Joyce Hopkins, Fred Bryant
Gene X Environment Effects Of Serotonin Transporter, Dopamine Receptor D4, And Monoamine Oxidase A Genes With Contextual And Parenting Risk Factors On Symptoms Of Oppositional Defiant Disorder, Anxiety, And Depression In A Community Sample Of 4-Year-Old Children, John Lavigne, Laura Herzing, Edwin Cook, Susan Lebailly, Karen Gouze, Joyce Hopkins, Fred Bryant
Fred B. Bryant
Genetic factors can play a role in the multiple level of analyses approach to understanding the development of child psychology. The present study examined gene-environment correlations and Gene x Environment interactions for polymorphisms of three target genes, the serotonin transporter gene, the D4 dopamine reactor gene, and the monoamine oxidase A gene in relation to symptoms of anxiety, depression, and oppositional behavior. Saliva samples were collected from 175 non-Hispanic White, 4-year-old children. Psychosocial risk factors included socioeconomic status, life stress, caretaker depression, parental support, hostility, and scaffolding skills. In comparison with the short forms (s/s, s/l) of the serotonin transporter …
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
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 …
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, …
Predictors Of Depression In Prostate Cancer Patients: A Comparison Of Psychological Resilience Versus Pre-Existing Anxiety And Depression, Christopher Sharpley, Vicki Bitsika, Addie Wootten, David Christie
Predictors Of Depression In Prostate Cancer Patients: A Comparison Of Psychological Resilience Versus Pre-Existing Anxiety And Depression, Christopher Sharpley, Vicki Bitsika, Addie Wootten, David Christie
Vicki Bitsika
Background: Previous anxiety and depression can influence current anxiety and depression, and psychological resilience may be a buffer against current anxiety and depression. However, despite the relevance of these two sets of predictors of anxiety and depression, and their potential in treatment planning, no reports have been published on their role in post-diagnosis anxiety and depression among prostate cancer (PCa) patients. Therefore, this study aimed to determine the roles of these predictors in a sample of men with prostate cancer. Method: Retrospective self-reports of anxiety and depression for how they were before receiving their diagnosis of PCa and at the …
