Mood Lifters for Graduate Students and Young Adults: A Mixed-Methods Investigation into Mechanisms of Change in Online Group Therapy.

Mood Lifters (ML) is a dimensional, group-based, peer-led mental health program that has shown efficacy in mitigating psychopathology and promoting wellness within a variety of populations. There is not yet evidence for mechanism(s) driving these changes. Qualitative data exploring the lived experiences of participants may be a unique way to develop hypotheses about the potential mechanisms driving change. The current study used qualitative and quantitative data from the ML for Graduate Students (ML-GS) and Young Adults (ML-YA) studies to generate hypotheses regarding potential mechanisms of changes experienced in ML. Seventy-nine graduate students and fifty-nine non-student young adults provided quantitative and qualitative feedback after participating in a 12-week virtual ML program. Inductive qualitative analysis was conducted within a reflexive thematic framework. Descriptive statistics of quantitative measures were also calculated. Three themes suggest potential directions for future mechanism research on virtual ML programs. Most participants emphasized the social connections built in groups as the most potent and powerful aspects of ML, while others focused on the design or content of the program. Quantitative data presented contextualize the lived experiences of participants. Future ML research should explore the three themes identified within this study through continued qualitative and quantitative data collection and analysis. NCT05078450.

Mood Lifters for college athletes: a biopsychosocial approach to improving mental health for student-athletes.

Objective: Mood Lifters, a biopsychosocial mental wellness program, has been shown to improve mental health in adults and senior citizens. This study examines the efficacy of the adaptation of the original program, hypothesizing that the Mood Lifters - Athlete version would improve collegiate athletes' anxiety and depression. Participants: Participants included fifty-two student-athletes recruited through The Invisible Opponent, an organization focused on student-athlete mental health awareness, and directly through an R1 University Athletic Department. Methods: Repeated-measures analysis of variance (ANOVAs) was conducted to evaluate the change in self-reported assessments of well-being at the start and end of the intervention. Results: Mood Lifters significantly improved participants' depression, anxiety, and self-esteem. Conclusion: Student-athletes showed improvements in mental well-being across several measures. The findings should be replicated in a larger trial with a more diverse sample to fully understand the impact of Mood Lifters.

Treatment for graduate students: Blunting the emotional toll of postgraduate education.

OBJECTIVES: Graduate students are at greater risk of developing mental health concerns than other adults in their age group. Despite the need for care within this population, there is a lack of literature on accessible interventions designed specifically to meet the needs of graduate students. The present study examines the efficacy of a novel intervention: Mood Lifters for Graduate Students (ML-GS). METHOD: This study is a clinical trial with randomization. The sample size consisted of 131 participants. The average age was 25.95 years, and the sample was 88.5% women, 61.8% White, and 65.6% straight or heterosexual. Participants completed the same survey before and after participating in ML-GS, as well as 1-month after completing ML-GS. Three measures from those surveys were examined in this study: Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Perceived Stress Scale. Two-way mixed-design analyses of variance (ANOVAs) and repeated measures ANOVAs were used to analyze these data. RESULTS: Results indicated that participants enrolled in ML-GS experienced significant, clinically meaningful reductions in depression, anxiety, and stress, when compared to their waitlist counterparts. The changes made during the ML-GS program were also maintained at the 1-month follow-up. CONCLUSIONS: These findings suggest that ML-GS is effective in reducing depression, anxiety, and stress among graduate students. It may be a good solution for the large demand for mental health support in that population. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

An investigation into the effectiveness of Mood Lifters in the context of trauma exposure.

A large proportion of adults experiencing mental health problems do not receive care due to structural and attitudinal barriers. Mood Lifters (ML) is an evidence-based mental wellness program designed to reduce depression, anxiety, and stress symptoms. This study aims to extend the literature by examining whether ML reduces posttraumatic stress disorder (PTSD) symptoms, and if childhood trauma (CT) affects treatment outcomes. We hypothesized that ML will be effective for all symptoms. However, we predicted that those who endorse higher levels of CT would experience a diminished impact of ML on their symptoms. Graduate students and young professionals (N = 221), a demographic that is known to have greater mental health concerns, were randomly assigned to either the waitlist condition (n = 78) or the intervention condition (n = 143). Before and after ML participation, participants completed a series of questionnaires about their symptoms. ML reduced symptoms of PTSD for participants who received the intervention relative to the waitlist. Further, we also observed that while the overall regression models with CT predict posttreatment scores for all the clinical symptoms, the CT variable itself was predictive of only posttreatment anxiety. Unexpectedly, given that CT is often associated with less improvement, we found that those at all levels of CT experienced similar reductions in depression, anxiety and PTSD symptoms. Taken together, ML is a viable option to help people reduce depression, anxiety, stress, and PTSD regardless of the level of CT exposure.

From "surviving to thriving": Mood Lifters - a wellness program for parents of medically complex children.

OBJECTIVES: Parents of medically complex children juggle unique demands associated with caring for chronically ill children, many of which negatively impact their mental wellbeing. Despite this, parents of medically complex children often forgo mental health support due to concerns with costs, time, stigma, and accessibility. There is limited research on evidence-based interventions addressing such barriers for these caregivers. We piloted an adapted version of Mood Lifters, a peer-led wellness program, to equip parents of medically complex children with evidence-based strategies to manage their mental health while also reducing barriers to support. We hypothesized parents would find Mood Lifters to be feasible and acceptable. Further, parents would experience improvements in mental wellbeing upon program completion. METHODS: We conducted a single-arm prospective pilot study to assess Mood Lifters for parents of medically complex children. Participants included 51 parents in the U.S. recruited from a local pediatric hospital providing care for their children. Caregiver mental wellbeing was assessed through validated questionnaires pre-intervention (T1) and post-intervention (T2). Repeated-measures analysis of variance was conducted to evaluate change between T1 and T2. RESULTS: Analyses from T1 and T2 (n = 18) revealed improvements in parents' depression (F(1,17) = 7.691, p = 0.013) and anxiety (F(1,17) = 6.431, p = 0.021) after program completion. Improvements in perceived stress and positive and negative emotion were significant at p < 0.0083. SIGNIFICANCE OF RESULTS: Parents of medically complex children experienced improved mental health upon participating in Mood Lifters. Results offer preliminary support for the feasibility and acceptability of Mood Lifters as an evidence-based care option that may also alleviate common barriers to care.

Reductions in regional theta power and fronto-parietal theta-gamma phase-amplitude coupling during gaze processing in bipolar disorder.

Impaired social cognition is common in bipolar disorder (BD) and predicts poor functional outcomes. A critical determinant of social cognition is the ability to discriminate others' gaze direction, and its alteration may contribute to functional impairment in BD. However, the neural mechanisms underlying gaze processing in BD are unclear. Because neural oscillations are crucial neurobiological mechanisms supporting cognition, we aimed to understand their role in gaze processing in BD. Using electroencephalography (EEG) data recorded during a gaze discrimination task for 38 BD and 34 controls (HC), we examined: theta and gamma power over bilateral posterior and midline anterior locations associated with early face processing and higher-level cognitive processing, and theta-gamma phase-amplitude coupling (PAC) between locations. Compared to HC, BD showed reduced midline-anterior and left-posterior theta power, and diminished bottom-up/top-down theta-gamma PAC between anterior/posterior sites. Reduced theta power and theta-gamma PAC related to slower response times. These findings suggest that altered theta oscillations and anterior-posterior cross-frequency coupling between areas associated with higher-level cognition and early face processing may underlie impaired gaze processing in BD. This is a crucial step towards translational research that may inform novel social cognitive interventions (e.g., neuromodulation to target specific oscillatory dynamics) to improve functioning in BD.

Reduced theta-band neural oscillatory activity during affective cognitive control in bipolar I disorder.

Individuals with bipolar I disorder (BD) have difficulty inhibiting context-inappropriate responses. However, neural mechanisms of impaired cognitive control over impulsive behaviors, especially in response to emotion, are unclear. Theta-band neural oscillatory activity over midfrontal areas is thought to reflect cognitive control. The current study examined behavioral performance and theta-band activity during inhibition to affective stimuli in BD, relative to healthy control participants (HC). Sixty-seven participants with BD and 48 HC completed a Go/No-Go task with emotional face stimuli during electroencephalography (EEG) recording. Behavior was measured with reaction time, discriminability (d') and response bias (ß). Time-frequency decomposition of EEG data was used to extract event-related theta-band (4-7 Hz) neural oscillatory power and inter-trial phase consistency (ITPC) over midline fronto-central areas. Behavior and theta-band activity were compared between groups, while covarying for age. Participants with BD exhibited slower response execution times on correct Go trials and reduced behavioral discrimination of emotional versus neutral faces, compared to HC. Theta-band power and ITPC were reduced in BD relative to HC. Theta-band power was higher on No-Go trials than Go trials. The magnitude of differences in theta-band activity between Go/No-Go trial types did not differ between groups. Increased theta-band power was associated with faster response execution times, greater discrimination of differing facial expressions, and stronger tendency to respond both across the full sample and within the BD group. Attenuated midline fronto-central theta-band activity may contribute to reduced cognitive control and maladaptive behavioral responding to emotional cues in individuals with BD.

Mood Lifters for Seniors: Development and Evaluation of an Online, Peer-Led Mental Health Program for Older Adults.

Effective, scalable mental health programs are greatly needed for older adults. In this study, Mood Lifters-a peer-led, community-based program promoting mental well-being-was adapted to more specifically address the needs of older adults. Two groups completed the 14-week program via Zoom. A total of 24 participants enrolled (M age = 72 years), with 20 (83%) completing the program. Compared to baseline, program completers showed significant improvements in depression symptoms (p < .01), perceived stress (p = .04), sleep quality (p < .01), physical activity (p < .01), and brain health behaviors (p = .01), with improvements maintained at 1-month follow-up. No significant changes were reported in participants' anxiety, loneliness, or resilience. Participant ratings of program satisfaction were very high (M = 4.75/5). Results suggest Mood Lifters for Seniors is feasible to disseminate and acceptable to older adults, with preliminary evidence of benefits in several mental health domains. Future randomized trials with larger, more diverse samples are needed to confirm program benefits.

Adapting user-centered design principles to improve communication of peer parent narratives on pediatric tracheostomy.

BACKGROUND: Parents who have to make tracheostomy decisions for their critically ill child may face forecasting errors and wish to learn from peer parents. We sought to develop an intervention with peer parent narratives to help parents anticipate and prepare for future challenges before making a decision. METHODS: To ensure that the intervention reflects parents' needs (rather than experts' opinions), we adapted a user-centered design (UCD) process to identify decision-critical information and refine the presentation format by interviewing parents who had tracheostomy decision making experience. Phase 1 (n = 10) presented 15 possible forecasting errors and asked participants to prioritize and justify the problematic ones. It also asked participants to comment on the draft narratives and preferred delivery mode and time of the intervention. Phase 2 (n = 9 additional parents and 1 previous parent) iteratively collected feedback over four waves of user interviews to guide revisions to the informational booklet. RESULTS: Phase 1 revealed that parents wanted information to address all forecasting errors as soon as tracheostomy becomes an option. They also highlighted diverse family situations and the importance of offering management strategies. The resulting prototype booklet contained five sections: introduction, child's quality of life, home care, practical challenges, and resources. Feedback from Phase 2 focused on emphasizing individualized situations, personal choice, seriousness of the decision, and caregiver health as well as presenting concrete illustrations of future challenges with acknowledgement of positive outcomes and advice. We also learned that parents preferred to use the booklet with support from the care team rather than read it alone. CONCLUSIONS: A UCD process enabled inclusion of parental perspectives that were initially overlooked and tailoring of the intervention to meet parental expectations. Similar UCD-based approaches may be valuable in the design of other types of patient communications (e.g., decision aids).

Event-related potential correlates of affective response inhibition in bipolar I disorder: Comparison with schizophrenia.

BACKGROUND: Individuals with bipolar I disorder (BD) have difficulty inhibiting context-inappropriate responses. The neural mechanisms contributing to these difficulties, especially in emotional contexts, are little understood. This study aimed to inform mechanisms of impaired impulsivity control in response to emotion in BD, and whether response inhibition indices are altered to a similar degree in schizophrenia spectrum disorders (SZ). We examined alterations to behavioral performance and event-related potentials (ERPs) during inhibition to affective stimuli in BD, relative to healthy control participants (HC) and SZ. METHODS: Sixty-six participants with BD, 32 participants with SZ, and 48 HC completed a Go/No-Go task with emotional face stimuli while electroencephalography was recorded. Behavioral signal detection metrics (perceptual sensitivity, response bias) and ERPs (N200, P300) were compared across groups. RESULTS: Relative to HC, participants with BD showed reduced (1) discrimination of Go vs. No-Go stimuli (i.e., emotional vs. neutral faces), and (2) P300 amplitudes elicited by emotional faces. Results similarly extended to SZ: BD and SZ groups did not differ on behavioral performance nor ERP amplitudes. LIMITATIONS: Aspects of the Go/No-Go task design may have limited findings, and medication effects on ERP amplitudes in patient samples cannot be fully ruled out. CONCLUSIONS: Findings suggest the difficulty participants with BD and SZ experienced on the current affective response inhibition task lied largely in discriminating between facial expressions. Difficulties with discriminating emotional from neutral expressions may contribute to difficulties with appropriate behavioral responding in social-affective contexts for individuals with BD and SZ.

Exploration of baseline and early changes in neurocognitive characteristics as predictors of treatment response to bupropion, sertraline, and placebo in the EMBARC clinical trial.

BACKGROUND: Treatment for major depressive disorder (MDD) is imprecise and often involves trial-and-error to determine the most effective approach. To facilitate optimal treatment selection and inform timely adjustment, the current study investigated whether neurocognitive variables could predict an antidepressant response in a treatment-specific manner. METHODS: In the two-stage Establishing Moderators and Biosignatures of Antidepressant Response for Clinical Care (EMBARC) trial, outpatients with non-psychotic recurrent MDD were first randomized to an 8-week course of sertraline selective serotonin reuptake inhibitor or placebo. Behavioral measures of reward responsiveness, cognitive control, verbal fluency, psychomotor, and cognitive processing speeds were collected at baseline and week 1. Treatment responders then continued on another 8-week course of the same medication, whereas non-responders to sertraline or placebo were crossed-over under double-blinded conditions to bupropion noradrenaline/dopamine reuptake inhibitor or sertraline, respectively. Hamilton Rating for Depression scores were also assessed at baseline, weeks 8, and 16. RESULTS: Greater improvements in psychomotor and cognitive processing speeds within the first week, as well as better pretreatment performance in these domains, were specifically associated with higher likelihood of response to placebo. Moreover, better reward responsiveness, poorer cognitive control and greater verbal fluency were associated with greater likelihood of response to bupropion in patients who previously failed to respond to sertraline. CONCLUSION: These exploratory results warrant further scrutiny, but demonstrate that quick and non-invasive behavioral tests may have substantial clinical value in predicting antidepressant treatment response.

A preliminary study on the relationship between sleep, depression and cardiovascular dysfunction in a 4 sample population.

BACKGROUND: Major Depressive Disorder (MDD) has been linked in the literature to poorer prognosis in patients with cardiovascular dysfunction, although the mechanisms of this relationship remain unclear. Underlying Sleep Disordered Breathing (SDB) serves as a potential candidate to explain this effect due to its downstream effects on inflammatory activation and decreased nitric oxide (NO) bioavailability, both of which have been shown to contribute to the pathophysiology of both MDD and cardiovascular disease (CVD). METHODS: This study utilizes overnight polysomnography and an inflammation panel to examine the links between cardiovascular dysfunction and sleep difficulties in control participants and patients diagnosed with SDB only, MDD only, and both SDB and MDD. RESULTS: Results demonstrate a strong positive relationship between sleep dysfunction and the nitric oxide synthesis inhibitor Symmetric Dimethyl Arginine (SDMA) in the MDD-only cohort, suggesting a link between SDMA-mediated NO dysregulation and CVD pathogenesis in individuals with MDD. Additionally, hypopneas, a form of sleep impairment characterized by partial reduction of airflow, were found to play a significant role in the relationship between SDB and cardiovascular dysfunction in MDD-only patients. CONCLUSIONS: Results of this study demonstrate the need for widespread screening for SDB in MDD populations to detect predisposition to CVD, and also offer SDMA as a new potential target for CVD treatment in individuals with MDD.

Sleep quality and neuropsychological functioning in bipolar I disorder.

BACKGROUND: Individuals with bipolar I disorder (BD-I) experience both poor sleep and neuropsychological dysfunction relative to non-psychiatric populations, which limits functional recovery. Poor sleep adversely affects learning, memory, and executive functioning in healthy individuals; however, little is known about the role of poor sleep in neuropsychological functioning in BD-I. We tested whether sleep disturbance was greater in BD-I than healthy control participants (HC), and compared the effect of sleep quality on learning, memory, and executive functioning between BD-I and HC. METHODS: Participants with BD-I (N=250) and HC (N=206) completed the Pittsburgh Sleep Quality Index, neuropsychological testing, and clinician-administered mood measures as part of a naturalistic study of bipolar disorder. We examined effects of both diagnosis and sleep quality on neuropsychological functioning. RESULTS: Relative to HC, BD-I showed poorer sleep quality and neuropsychological functioning in verbal learning, verbal and visual memory, processing speed, psychomotor speed, inhibitory control, and selective attention (7/9 domains). Poor sleep quality was associated with poorer verbal learning, verbal fluency, processing speed, and interference control (4/9). Effects of poor sleep on neuropsychological functioning did not differ between BD-I and HC. LIMITATIONS: The assessment of sleep quality using a self-report measure and the effects of medications/sleeping aids (given the naturalistic study design) should be considered when interpreting results. CONCLUSIONS: Those with BD-I experiencing poor sleep may also be more vulnerable to verbal learning and executive functioning impairments. The findings of poor sleep in relation to poorer neuropsychological functioning have implications for assessment and treatment of sleep disturbance in BD-I.

Using Narratives to Correct Forecasting Errors in Pediatric Tracheostomy Decision Making.

PURPOSE: Parents who face goals-of-care tracheostomy decisions may lack an understanding of challenges affecting their child's and family's long-term quality of life (QOL) to accurately forecast possible outcomes for decision making. We sought to examine whether and how parents' narratives of the child's and family's long-term QOL influence parental tracheostomy decisions and forecasting. METHOD: We recruited US adult Amazon Mechanical Turk participants (N = 1966) who self-reported having a child (<6 y old) or planning a pregnancy within 5 y. Participants read a vignette about making a tracheostomy decision for their hypothetical neurologically impaired baby. They were randomized to 1 of the following 4 conditions: 1) Baby QOL narratives, 2) Family QOL narratives, 3) Baby QOL + Family QOL narratives, and 4) control: no narratives. They then made a decision about whether or not to pursue tracheostomy, forecasted their concerns about the baby's and family's QOL, reported their values and social norm beliefs about tracheostomy, comfort care, and parental medical decision making, and completed individual differences scales and demographics. RESULTS: Controlling for individual characteristics, participants in the Baby QOL and Baby QOL + Family QOL conditions were less likely to choose tracheostomy as compared with the control (odds ratio [OR] = 0.38 and 0.25, respectively, P < 0.001). Fewer participants in the Family QOL condition chose tracheostomy compared with the control, but this difference was not statistically significant (OR = 0.70, P = 0.11). Moreover, narratives increased pessimistic forecasting, which was associated with less interest in tracheostomy. CONCLUSION: Narratives clarifying long-term implications of pursuing tracheostomy have the potential to influence forecasting and decisions. Narrative-based interventions may be valuable in other situations in which forecasting errors are common.

Preliminary Evidence for Sociotropy and Autonomy in Relation to Antidepressant Treatment Outcome.

Sociotropy and autonomy are cognitive-personality styles that have been hypothesized to confer vulnerability to different presentations of major depressive disorder (MDD), which may respond differentially to treatment. Specifically, the profile of low sociotropy and high autonomy is hypothesized to indicate a positive response to antidepressant medication. The current study examines sociotropy and autonomy in relation to sertraline treatment response in individuals with MDD. As part of an ancillary study to the larger Establishing Moderators and Biosignatures of Antidepressant Response for Clinical Care (EMBARC) project, individuals with MDD participated in an 8-week trial of sertraline and completed a self-report questionnaire of sociotropy and autonomy. Discriminant function analyses were used to examine whether sociotropy and autonomy scores could distinguish antidepressant treatment responders (determined by a 50% or greater reduction in depressive symptoms) from non-responders. The sociotropy scale successfully discriminated sertraline treatment responders from non-responders. Further, lower sociotropy was associated with greater improvements in depressive symptomology following sertraline treatment. The current findings suggest individuals with MDD characterized by low sociotropy are more likely to benefit from sertraline. Given the promising results of the Sociotropy-Autonomy Scale in discriminating treatment responders from non-responders, the low resources necessary for administration, and the ease of translation into routine clinical care, the scale warrants further research attention.

Neural Oscillatory Abnormalities During Gaze Processing in Schizophrenia: Evidence of Reduced Theta Phase Consistency and Inter-areal Theta-Gamma Coupling.

BACKGROUND: Abnormal gaze discrimination in schizophrenia (SZ) is associated with impairment in social functioning, but the neural mechanisms remain unclear. Evidence suggests that local neural oscillations and inter-areal communication through neural synchronization are critical physiological mechanisms supporting basic and complex cognitive processes. The roles of these mechanisms in abnormal gaze processing in SZ have not been investigated. The present study examined local neural oscillations and connectivity between anterior and bilateral posterior brain areas during gaze processing. METHODS: During electroencephalography recording, 28 participants with SZ and 34 healthy control participants completed a gaze discrimination task. Time-frequency decomposition of electroencephalography data was used to examine neural oscillatory power and intertrial phase consistency at bilateral posterior and midline anterior scalp sites. In addition, connectivity between these anterior and posterior sites, in terms of cross-frequency coupling between theta phase and gamma amplitude, was examined using the Kullback-Leibler Modulation Index. RESULTS: Participants with SZ showed reduced total power of theta-band activity relative to healthy control participants at all sites examined. This group difference could be accounted for by reduced intertrial phase consistency of theta activity in SZ participants, which was related to reduced gaze discrimination accuracy in SZ. In addition, SZ participants exhibited reduced Kullback-Leibler indexing, both feedforward and feedback connectivity, between the posterior and anterior sites. CONCLUSIONS: These findings suggest that abnormal theta phase consistency and dysconnection between posterior face processing and anterior areas may underlie gaze processing deficits in SZ.

Anxiety Mediates the Relationship between Psychotic-Like Experiences and Social Functioning in the General Population.

INTRODUCTION: Within the psychosis continuum that includes schizophrenia (SZ) at the severe end and the general population at the mild end, anxiety may negatively impact social functioning more than psychosis or psychotic-like experiences (PLE). This claim is supported by previous reports that show anxiety mediates the relationship between psychosis and social functioning in SZ, suggesting anxiety is critical to social functioning in SZ. Yet no studies have examined a similar relationship in the general population, and this is important because people with PLE are at a significantly higher risk for developing full-blown psychosis. METHODS: Similar to those with SZ, we predicted heightened anxiety would mediate the relationship between PLE, as measured by The -Oxford-Liverpool Inventory of Feelings and Experiences, and social functioning, as measured by Social Adjustment Scale - Self-Report, in the general population. RESULTS: Indeed, the current study showed that the relationship between PLE and social functioning was mediated by anxiety (z = 7.81, p < 0.001) within an unselected crowdsourcing sample representative of the general population (Amazon M-Turk; n = 197, mean age 32.38 years). CONCLUSION: Taken together with previous reports, the current findings suggest that anxiety is a functionally relevant dimension across the psychosis continuum and improving anxiety may improve social functioning across this continuum.

Pretreatment Reward Sensitivity and Frontostriatal Resting-State Functional Connectivity Are Associated With Response to Bupropion After Sertraline Nonresponse.

BACKGROUND: Standard guidelines recommend selective serotonin reuptake inhibitors as first-line antidepressants for adults with major depressive disorder, but success is limited and patients who fail to benefit are often switched to non-selective serotonin reuptake inhibitor agents. This study investigated whether brain- and behavior-based markers of reward processing might be associated with response to bupropion after sertraline nonresponse. METHODS: In a two-stage, double-blinded clinical trial, 296 participants were randomized to receive 8 weeks of sertraline or placebo in stage 1. Individuals who responded continued on another 8-week course of the same intervention in stage 2, while sertraline and placebo nonresponders crossed over to bupropion and sertraline, respectively. Data from 241 participants were analyzed. The stage 2 sample comprised 87 patients with major depressive disorder who switched medication and 38 healthy control subjects. A total of 116 participants with major depressive disorder treated with sertraline in stage 1 served as an independent replication sample. The probabilistic reward task and resting-state functional magnetic resonance imaging were administered at baseline. RESULTS: Greater pretreatment reward sensitivity and higher resting-state functional connectivity between bilateral nucleus accumbens and rostral anterior cingulate cortex were associated with positive response to bupropion but not sertraline. Null findings for sertraline were replicated in the stage 1 sample. CONCLUSIONS: Pretreatment reward sensitivity and frontostriatal connectivity may identify patients likely to benefit from bupropion following selective serotonin reuptake inhibitor failures. Results call for a prospective replication based on these biomarkers to advance clinical care.
