Relation Of Depression Symptoms To Sustained Reward And Loss Sensitivity, Michael P. Berry, Ema Tanovic, Jutta Joormann, Charles A. Sanislow Feb 2019

Relation Of Depression Symptoms To Sustained Reward And Loss Sensitivity, Michael P. Berry, Ema Tanovic, Jutta Joormann, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

Depression is characterized by altered sensitivity to rewards, with recent evidence suggesting that the ability to sustain responses to rewards across long experimental tasks is diminished. Most work on sustained reward responsiveness has taken a cat- egorical approach and focused on major depressive disorder. However, impairments in reward sensitivity are also found at lower levels of symptom severity and may be relevant for understanding basic mechanisms linking reward processing abnormali- ties to depression. The current study took a dimensional approach to examine the relation between depression symptoms and sustained reward responsiveness by examining how early neural responses to rewards and …


Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant Dec 2015

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 Dec 2015

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 …


Help-Negation And Suicidal Ideation: The Role Of Depression, Anxiety And Hopelessness., Coralie J. Wilson Dec 2009

Help-Negation And Suicidal Ideation: The Role Of Depression, Anxiety And Hopelessness., Coralie J. Wilson

Frank Deane

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 Dec 2006

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 …
