It’S All The Rage: An Animated Approach To Screening For Postpartum Depression, Amanda Gorham Dec 2020

It’S All The Rage: An Animated Approach To Screening For Postpartum Depression, Amanda Gorham

Doctoral Dissertations

Postpartum depression presents a complication for mothers which can, in some cases, be severe and even life-threatening. Instruments commonly used to screen for this psychological condition have been challenged by an extensive body of literature, with many mothers being unidentified and even untreated for their symptoms. The presented research introduces a newly developed screening instrument for detecting probable postpartum depression using text-free scenario-based animations, based on the lived experience of the condition as qualified by empirical research and the existing body of literature. Developed items were controlled for quality via Think Aloud Protocol and alignment studies with subject matter experts …


Comparison Of Public Mental Health Stigma In Youth, Desiree A. Clarke Dec 2020

Comparison Of Public Mental Health Stigma In Youth, Desiree A. Clarke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study looked at mental health stigma in youth. Mental health stigma is devaluing, disgracing and disfavoring individuals with mental illness. Participants aged 11-14 completed a measure to rate their stigmatizing beliefs toward peers with either ADHD, depression, or asthma. Their ratings were compared for significance between genders and for the three different conditions: ADHD, depression, and asthma. Significant differences were found between the stigma ratings for asthma, depression and ADHD. ADHD had significantly higher stigma ratings than asthma, and depression had significantly higher stigma ratings than ADHD (on some, but not all, areas rated) and had consistently higher …


The Effects Of Military Sexual Trauma And Depressive Symptoms On Reintegration, Rachel L. Davies Dec 2020

The Effects Of Military Sexual Trauma And Depressive Symptoms On Reintegration, Rachel L. Davies

Psychology Theses & Dissertations

Reintegration is a challenge for many veterans returning to civilian roles after military service. Difficulties range from an assortment of issues such as self-care to community participation. Military sexual trauma may be an experience that alters or changes veterans and result in difficulty in reintegration. Specifically, it was predicted that military sexual trauma would indirectly affect reintegration, via depressive symptoms. In addition, locus of control was predicted to play a role in how military sexual trauma impacts reintegration with external locus of control acting as a buffer. Participants were a cross-sectional community sample of both female veterans who reported having …


Counseling Clients With Traumatic Brain Injury: Exploring Counselors’ Perceived Knowledge, Comfort, And Self-Awareness, Michelle Bradham-Cousar Nov 2020

Counseling Clients With Traumatic Brain Injury: Exploring Counselors’ Perceived Knowledge, Comfort, And Self-Awareness, Michelle Bradham-Cousar

USF Tampa Graduate Theses and Dissertations

The number of traumatic brain injury (TBI) diagnoses continues to rise each year. Counseling is a critical factor in TBI treatment, and although numerous studies have investigated TBI outcomes, a paucity of researchers have studied professional counselors’ knowledge, comfort, and self-awareness when working with TBI clients. Due to the diversity of counselor caseloads, it is likely that counselors will serve clients with a dual diagnosis that includes TBI. These dual diagnoses include depression, posttraumatic stress disorder, anxiety, psychosis, or another neurocognitive disorder. The purpose of this study was to explore counselors’ knowledge, comfort, and self-awareness when working with individuals with …


Predictors Of Recovery In Advocacy-Based Refugee Treatment Outcome: The Role Of Prior Traumatic Experiences And Current Chronic Stressors, Meredith A. Blackwell Oct 2020

Predictors Of Recovery In Advocacy-Based Refugee Treatment Outcome: The Role Of Prior Traumatic Experiences And Current Chronic Stressors, Meredith A. Blackwell

Psychology ETDs

Refugees are at an increased vulnerability to mental health disorders compared to citizens of wealthier nations. The present study looks at the symptom trajectories of 290 refugees in a psychosocial community-based participatory intervention. A three-level generalized linear mixed model examined the predictive impact of exposure to trauma and chronic stress at baseline on posttraumatic stress and mood symptoms over time. Results showed that only higher chronic stress at baseline was associated with a steeper decrease in both PTSD and mood scores, but these effects differed by nationality. However, with chronic stress entered as a time-varying covariate instead only African participants …


Generating Alternative Solutions When Depression Is The Problem, Benjamin Todd Johnson Oct 2020

Generating Alternative Solutions When Depression Is The Problem, Benjamin Todd Johnson

Dissertations (1934 -)

Generating alternative solutions for problem situations is a key component of effective problem solving. This process is used to generate a variety of potential options for managing a problem, from which the most effective approach or combination of approaches can be selected for implementation. Impaired alternatives generation provides fewer options from which to select a response, reducing the likelihood that a highly effective approach will be available for implementation, potentially leaving problems unresolved, generating additional problems, and fostering a sense of hopelessness and depression. Depression has been found to impair problem solving further by reducing engagement in the problem solving …


Assessing A Cognitive Model Of Trauma-Related Sleep Disturbance, Rebecca Chesher Sep 2020

Assessing A Cognitive Model Of Trauma-Related Sleep Disturbance, Rebecca Chesher

Dissertations

Sleep disturbance is a symptom of many mental health disorders that may negatively affect cognition and mood. Trauma-related sleep disturbance is a core reaction of traumatic stress and PTSD, similar to symptoms experienced by individuals with insomnia or other sleep-wake disorders. Although the cause and symptom progression of trauma-related sleep disturbance may be very different, research and clinical practice assess and treat it with measures and interventions designed for general insomnia. Using a cognitive model of insomnia modified for trauma-related sleep disturbance, the current study assessed the relations between select trauma and sleep variables within the proposed constructs of: 1) …


Insomnia In Subclinical Paranoid Participants, Lauren J. Bennett-Leleux Aug 2020

Insomnia In Subclinical Paranoid Participants, Lauren J. Bennett-Leleux

Psychology and Counseling Theses

Insomnia has always been thought to be a consequence of schizophrenia and may be predicted by paranoid thoughts. Individuals with a diagnosis of schizophrenia have reported symptoms of insomnia, which can in turn increase psychosis. It is thought that these symptoms can come from decreased daytime activity, reduced cognitive functioning, or distress from psychotic experiences increasing arousal (Waite et al., 2016a; Hodgenkins et al., 2015; Stubbset et al., 2016). However, recent evidence has demonstrated that insomnia can predict later paranoid thoughts. Individuals with comorbid psychotic disorder and insomnia tend to have more severe psychotic experiences such as paranoid thoughts (Freeman …


Affective, Physiological, And Cognitive Response To Imagery- And Verbally-Based Rumination And Distraction In Adolescence, Hannah Lawrence Aug 2020

Affective, Physiological, And Cognitive Response To Imagery- And Verbally-Based Rumination And Distraction In Adolescence, Hannah Lawrence

Electronic Theses and Dissertations

To date, rumination and interventions for rumination have largely been verbal in focus. Rumination has been conceptualized as dwelling on negative affect in the form of verbal thought, and interventions aim to interrupt cycles of rumination using verbal strategies. Yet, emerging evidence suggests that many individuals dwell on negative affect in the form of imagery (e.g., Lawrence, Haigh, Siegle, & Schwartz-Mette, 2018) and that imagery-based interventions may be even more effective (e.g., Arntz, 2012). This is not surprising as imagery is more affectively arousing (Holmes & Mathews, 2010), physiologically stimulating (Vrana, Cuthbert, & Lang, 1986), and realistic/vivid (Mathews, Ridgeway, & …


Personalized Models Of Social Anxiety Disorder And Depression, Marilyn L. Piccirillo Aug 2020

Personalized Models Of Social Anxiety Disorder And Depression, Marilyn L. Piccirillo

Arts & Sciences Electronic Theses and Dissertations

Social anxiety disorder (SAD) is an important risk factor for major depressive disorder (MDD) and together this comorbidity constitutes a highly impairing syndrome and vicious cycle of symptomatology, associated with tremendous health costs and societal burden. Despite much group-level research examining risk factor for MDD specifically, there is limited group and individual-level research evaluating how individuals with SAD transition into depressive episodes. Clinical and theoretical evidence suggests that each patient may exhibit a unique personalized pattern of risk factors. These idiographic patterns may contradict relationships seen at the group level. In this dissertation, women (N = 35) with SAD and …


Decision-Making Difficulty In Major Depression: Understanding Indecisiveness And The Role Of Expected Affect, Haijing Wu Hallenbeck Aug 2020

Decision-Making Difficulty In Major Depression: Understanding Indecisiveness And The Role Of Expected Affect, Haijing Wu Hallenbeck

Arts & Sciences Electronic Theses and Dissertations

Decision-making difficulty is a prevalent symptom among individuals with major depressive disorder (MDD). Decision-making difficulty has been found to be pervasive across different areas of decision-making in current MDD; however, its exact nature for some areas (e.g., indecisiveness) is not well characterized, and the extent to which it is a scar of MDD is not determined. Furthermore, affective disturbances (e.g., in expected affect) have been theorized to contribute to decision-making difficulty in MDD, but empirical studies are needed to test this theory. In my two-study dissertation on depression, Study 1 focused on the dimensionality and validity of indecisiveness, and Study …


Assessing Sex Differences In The Effects Of Short-Term Rem Sleep On Anxiety- And Depressive-Like Behaviors In Rats, Nadia Meshkati Aug 2020

Assessing Sex Differences In The Effects Of Short-Term Rem Sleep On Anxiety- And Depressive-Like Behaviors In Rats, Nadia Meshkati

Seton Hall University Dissertations and Theses (ETDs)

Findings from both human and animal studies suggest rapid eye movement (REM) sleep disturbances following a traumatic event can lead to inability to extinguish the fear association, and eventually influence the development of post-traumatic stress disorder (PTSD). Additionally, research has demonstrated that sleep disruptions, including REM sleep deprivation (RSD), increases anxiety- and depressive-like behaviors and states in animals and people, with evidence of sex differences. Furthermore, it has yet to be determined whether short-term RSD, a more natural animal model of PTSD, can influence affective state of subjects. The present study applied short-term RSD to investigate sex differences in the …


Examination Of The Relationship Between Sport-Specific Thoughts And Emotions And Anxiety And Depression In College Athletes, Marina Elizabeth Harris Aug 2020

Examination Of The Relationship Between Sport-Specific Thoughts And Emotions And Anxiety And Depression In College Athletes, Marina Elizabeth Harris

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression and anxiety are prevalent mental health difficulties affecting student athletes, who notoriously reject mental health interventions that are not sport-relevant. This study will assist in understanding the extent to which sport-relevant thoughts and emotions impact depression and anxiety in collegiate athletes. Two-hundred and twenty-five NCAA athletes competing at the Division, I, II, or III level were administered the Sport Interference Checklist (SIC), Test of Performance Strategies (TOPS), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire (PHQ-9). Results of correlational analyses revealed a significant relationship between SIC Dysfunctional Thinking (in training and competition) and anxiety (GAD-7) and depressive (PHQ-9) symptoms, …


Trauma Exposure, Depressive Symptoms, And Responding To Positive Events And Affect In Young Adults, Jana Desimone Wozniak Jun 2020

Trauma Exposure, Depressive Symptoms, And Responding To Positive Events And Affect In Young Adults, Jana Desimone Wozniak

Clinical Psychology Dissertations

The relationship between trauma exposure and responding to positive affect and events is unclear. Depression may co-occur with trauma exposure, and may also independently predict responding to positive affect and events. The purpose of this study was to examine the relationships between trauma exposure, depressive symptoms, and responding to positive affect and positive life events among young adults. Participants were 277 (84.8% female, 56.3% Caucasian) undergraduates ages 18-39 (M = 19.67, SD = 2.22). At baseline, ANCOVAs were used to examine the relationships between trauma exposed/non-trauma exposed groups, as well as high/low depressive symptom groups, on responding to positive …


Do Anxiety, Depression, And Mental Health Treatment Impact Christian College Student Religiosity/Spirituality?, Matthew J. Ditty Jun 2020

Do Anxiety, Depression, And Mental Health Treatment Impact Christian College Student Religiosity/Spirituality?, Matthew J. Ditty

Doctor of Psychology (PsyD)

The majority of Americans report religious affiliation and participate in religious practices. Several studies have sought to analyze the protective factors of religiosity, especially as it relates to mental and physical health issues. However, little research has been conducted which explores the relationship between religiosity/spirituality (R/S), mental health, and its treatment status.

This study sought to determine whether participants’ mental health problems (anxiety and depression) and treatment status (treatment versus no treatment) were related to their religiosity/spirituality and if severity of pathology and treatment engagement significantly affected R/S. Results suggest subjects can be aggregated into two meaningful groups: one that …


Depression, Music Choice, And Affective Outcomes In Daily Life, Sunkyung Yoon Jun 2020

Depression, Music Choice, And Affective Outcomes In Daily Life, Sunkyung Yoon

USF Tampa Graduate Theses and Dissertations

Persons with depression consistently report a preference for sad music. Are such preferences maladaptive or beneficial? We tested this question in a 3-part study that examined 77 participants’ (39 with and 38 without clinical depression) music choice in daily life, affective outcomes, and the reasons for music choice. During a 3-day ecological momentary assessment (EMA), participants chose a song from a pre-set music library of happy and sad songs and rated their affect before and after hearing the chosen song. In addition, we analyzed the characteristics (e.g., tempo) of participants’ free song choices over 7 days (from participants’ Spotfiy music …


Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen O'Donnell Jun 2020

Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen O'Donnell

Electronic Theses, Projects, and Dissertations

As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …


The Association Between Problematic Internet Use, Depressive Symptoms, Selfesteem, And Personality Traits, Basma Mubarak Yaslam Bensumaidea Jun 2020

The Association Between Problematic Internet Use, Depressive Symptoms, Selfesteem, And Personality Traits, Basma Mubarak Yaslam Bensumaidea

Theses

A number of international studies have investigated the association between problematic internet use (PIU), personality traits, and psychopathology, however, despite their widespread prevalence, such investigations in the Middle East region remain rare. Therefore, this study examined the relationship between PIU and depression, self-esteem, and personality traits in a sample of 350 university students, aged between 17 and 33 years (mage=20.69, SD=2.14), who were residents in the United Arab Emirates (UAE). Participants completed several assessments of sociodemographic variables, a validated measure of PIU, depression, self-esteem, and a measure of their personality traits. A total of 75.1% of the sample was determined …


Depressed & Dis-Eased: Storytelling, Melancholia And The Rhetorical Affordances Of Affect, Carlee Franklin Jun 2020

Depressed & Dis-Eased: Storytelling, Melancholia And The Rhetorical Affordances Of Affect, Carlee Franklin

Electronic Theses, Projects, and Dissertations

Because racial oppression is often internalized, this thesis examines literature written by POC about protagonists of color struggling with depression. The pieces are Gwendolyn Brooks’ Maud Martha, Haruki Murakami’s “Tony Takitani,” and Junot Diaz’s The Brief Wondrous Life of Oscar Wao. Using literary concepts informed by Black feminist theory, decolonial theory, and affect studies, as well as rhetorical frameworks of silence and listening, this thesis attempts to better understand how the relationship between depression and racial oppression work to color the life expectancy and perspectives of depressed people of color


Moving Through Depression: Development Of A Dance/Movement Therapy Method In Psychiatric Inpatient Care, Melissa Olmedo May 2020

Moving Through Depression: Development Of A Dance/Movement Therapy Method In Psychiatric Inpatient Care, Melissa Olmedo

Expressive Therapies Capstone Theses

Short-term psychiatric hospitalization is a challenging health care model due to its short duration of care, treating the highest risk psychiatric population. Priority care within a short-term psychiatric hospitalization involves monitoring a patient’s safety for stabilization by decreasing acute mental health symptoms. Holistic psychotherapy treatment options are needed to meet the severity of patients’ symptoms for effective stabilization within a short-term model of care. This paper investigates the first implementation of a dance/movement therapy (DMT) method within two short-term units in a notable Boston hospital. The DMT group called Mindful Movement was facilitated weekly as single sessions to adults ranging …


Rhythm And Safety Of Social Engagement: Polyvagal Theory Informed Dance/Movement Therapy, Suzanne Weare May 2020

Rhythm And Safety Of Social Engagement: Polyvagal Theory Informed Dance/Movement Therapy, Suzanne Weare

Expressive Therapies Capstone Theses

The polyvagal theory has exerted great influence on the field of clinical therapy since the 1990s by proposing an understanding of the psychological expression seen in clients as a reflection of their physiological state of safety or threat of danger. When affect and psychological states are viewed through the lens of the autonomic nervous system directed by neuroception through bidirectional vagal nerve information, therapeutic presence and somatic therapy practices, such as those utilized in the field of dance/movement therapy, become more conceivable as best practices to treat a variety of psychological conditions to include trauma recovery, autism spectrum disorders, and …


Examination Of Sleep Disturbance, Anxiety Sensitivity, And Depression In An Undergraduate Sample, Dasha Grace May 2020

Examination Of Sleep Disturbance, Anxiety Sensitivity, And Depression In An Undergraduate Sample, Dasha Grace

Honors Theses

Sleep contributes to overall well-being, mental health, and daily functioning. Sleep disturbances negatively affect psychological, physiological, and biological processing, and the quality of sleep is similarly affected by these processes. The effects of sleep disturbance call for a greater understanding of depression and anxiety sensitivity among college students. Studies have found that sleep disturbance affects nearly 90% of the college student population. The aims of the current study were to examine: 1) types and rates of sleep disturbance among a sample of college students, 2) associations between sleep disturbance, AS, and depression symptoms, and 3) AS and depression symptoms by …


Socioeconomic Status And Symptoms Of Anxiety And Depression In Pregnant Women, Meagan Mandabach May 2020

Socioeconomic Status And Symptoms Of Anxiety And Depression In Pregnant Women, Meagan Mandabach

Honors Theses

Pregnancy is a period of great change in a woman’s body as her baby develops. During this period, women commonly experience symptoms of anxiety (Dennis et al., 2017) and depression (Shidhaye & Giri, 2014). Literature has suggested that socioeconomic status (SES) can contribute to the severity at which pregnant women experience anxiety and depression (Arora & Aeri, 2019; Field et al., 2008; Shagufta & Shams, 2019), and women of low socioeconomic status may be more likely to experience symptoms of anxiety and depression during pregnancy (Field et al., 2008). The present study aimed to assess the relationships between household income …


The Effects Of Antibiotics And Probiotics On Memory And Depression Across Age Groups, Amanda Powell May 2020

The Effects Of Antibiotics And Probiotics On Memory And Depression Across Age Groups, Amanda Powell

Masters Theses, 2020-current

The gut-brain axis is a bidirectional pathway that acts as a connection between the gut and the brain. Bacterial changes in the gut alter this pathway, affecting organism’s health, cognition, and behavior. Commensal bacteria in the gut can reduce inflammation and increase longevity while pathogenic bacteria can have opposite effects. Reduced commensal gut bacteria can result in an increase in stress activation, depression, and anxiety in both human and animal models. Increases in commensal bacteria and decreases in pathobiontic bacteria can decrease hypothalamic pituitary adrenal (HPA) system activation, anxious behavior, and depressive behavior. Alternatively, increases in pathobionts can lead to …


Peer Acceptance In The Lunchroom And Children’S Internalizing Symptoms, Jake Steggerda May 2020

Peer Acceptance In The Lunchroom And Children’S Internalizing Symptoms, Jake Steggerda

Graduate Theses and Dissertations

There is evidence to suggest that the context of the school lunchrooms provides children with rich opportunities for enhancing or hampering the quality of their relationships (Craig, Gregus, Elledge, Pastrana, & Cavell, 2016; Steggerda et al., in preparation). Although past research has linked children’s peer acceptance to their level of internalizing symptoms, few studies have examined peer acceptance within the lunchroom context. This study extends that work by examining associations between lunchroom peer acceptance (assessed via self- and peer-reports) and children’s internalizing symptoms. Participants were 676 fourth-grade students (50.7% female; 42.7% Hispanic/Latino, 30.3% White, 10% Pacific Islander, and 17% other) …


Depressive Symptoms And Survival Among Lung Cancer Patients: Biomarkers And Potential Benefits Of An Ipod- And Mindfulness-Based Intervention., Chelsea J. Siwik May 2020

Depressive Symptoms And Survival Among Lung Cancer Patients: Biomarkers And Potential Benefits Of An Ipod- And Mindfulness-Based Intervention., Chelsea J. Siwik

Electronic Theses and Dissertations

Lung cancer patients experience high levels of distress, which commonly manifests as depressive symptoms. Importantly, depressive symptoms have demonstrated prognostic significance in cancer contexts, although the biological pathways by which depressive symptoms lead to poorer survival remain unclear and warrant greater attention. In addition to understanding the biological pathways by which depressive symptoms accelerate disease, identification of efficacious and effective psychological treatments for depressive symptoms are needed to improve both quality and quantity of life for cancer patients. Interventions that reduce depressive symptoms and improve downstream clinical outcomes are certainty needed; however, because many cancer patients face considerable burden, interventions …


The Intersection Of Mindfulness And Gratitude: Examining The Roles Of Gratitude And Mindfulness Practices Within A 4-Week Mindfulness-Based Intervention On Depressive Symptoms In Undergraduates., Allison Rodgers May 2020

The Intersection Of Mindfulness And Gratitude: Examining The Roles Of Gratitude And Mindfulness Practices Within A 4-Week Mindfulness-Based Intervention On Depressive Symptoms In Undergraduates., Allison Rodgers

Electronic Theses and Dissertations

The practice and research of mindfulness has increased exponentially in recent decades; however, the study of gratitude maintains modest growth. While the overlap between gratitude and mindfulness may be intuitive, empirical investigation is lacking. The present study sought to investigate the relative and combined influence of mindfulness and gratitude with symptoms of depression in undergraduates. The current study explored these constructs in the context of a mindfulness-based intervention known as Koru. One hundred undergraduate participants provided self-report measures of demographics, mindfulness, gratitude, and symptoms of depression prior to the intervention and again immediately following. Participants were required to complete electronic …


An Investigation Of Anxiety- And Depression-Like Behavior After Head Trauma In Mice, Sean K. Payne May 2020

An Investigation Of Anxiety- And Depression-Like Behavior After Head Trauma In Mice, Sean K. Payne

Electronic Theses and Dissertations

Every year around 2 million people in the United States (US) suffer a traumatic brain injury. Those people are often at a higher risk of post-TBI psychiatric illness, like anxiety and depression. Animal models of TBI are a useful way to measure such psychiatric illnesses in a pre-clinical setting. There were two purposes of this study: the first being to test the modified Marmarou TBI model, and second to investigate anxiety- and depression-like symptoms in C57Bl6/J mice following a TBI. The modified Marmarou model used different weights (95g, 30g, & sham) to see how severity affected the manifestation of anxiety-like …


The Effectiveness Of Implementing A Collaborative Mental Health Approach On Quality Of Life For Individuals Of Low Socioeconomic Status, Tyler Z. Tooley May 2020

The Effectiveness Of Implementing A Collaborative Mental Health Approach On Quality Of Life For Individuals Of Low Socioeconomic Status, Tyler Z. Tooley

MSU Graduate Theses

The ultimate purpose of this study is to provide insight and education to mental health clinicians, politicians and the general public of the numerous effects poverty has on mental health, in addition to the most beneficial ways to combat those insidious effects. The specific barriers met by individuals of low socioeconomic status severely affect psychological and physical health, as well as social and environmental relationships, which therefore diminish overall quality of life. The aim of this study is to examine the effectiveness of implementing a collaborative mental health approach for low income individuals on length of engagement in services and …


Depressive Symptoms As A Moderator Of Diurnal Trends In Reward Seeking, Erick Albert William Rogers May 2020

Depressive Symptoms As A Moderator Of Diurnal Trends In Reward Seeking, Erick Albert William Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anhedonia, a cardinal symptom of a major depressive episode, is the decreased motivation to seek rewards. Individuals with depressive symptoms tend to report reduced positive affect, a distal measure of reward motivation, and engage in less reward-motivated behavior (i.e., reward seeking). However, diurnal rhythms may also influence reward-seeking. Both self-reported positive affect and behavioral measures of reward-seeking increase from the morning to the afternoon and then decreased in the evening. Therefore, the aim of this study was to examine whether reward-seeking varied across time of day and whether anhedonia moderated variation. Overall, reward-seeking did not vary across time of day. …
