Abstract
The ability to focus on and increase positive emotion in response to mental imagery may play a key role in emotional wellbeing. Moreover, deficits in this ability might underlie emotional disorders such as depression. Here, we set out to determine whether people could use savoring to upregulate subjective and electrocortical response to mental imagery of previously viewed positive and neutral pictures, and whether this would be negatively affected by depression. On each trial, participants (N = 49) viewed a positive or neutral picture, prior to simply re-imagining the previously presented picture ("view") or re-imagining the picture while savoring it ("savor"). Results showed that savoring increased electrocortical and subjective response to imagined stimuli; however, this effect was only evident at the electrocortical level when controlling for depression. Moreover, depression moderated electrocortical findings, such that individuals who were more depressed showed a reduced effect of savoring on neural response to mental imagery. Results are in line with recent work that has shown the benefits of positive affect treatment for depression, to suggest that deficits in savoring mental imagery may play a role in the development and/or maintenance of depression.

Abstract
Because social anxiety and depression commonly co-occur, it can be challenging to disentangle the emotional and motivational features of these conditions in everyday life contexts. In this daily diary study, we sought to understand the interplay between daily social anxiety and depression symptoms and emotion and motivation, determining whether daily symptoms are independently linked with positive affect, negative affect, and social motivation (desire to approach or to withdraw from others). Community-dwelling adults (N = 269) with a wide range of social anxiety and depression symptoms completed daily assessments for 14 consecutive days (a total of 2,986 daily surveys). Within-person analyses found that increases in social anxiety and depression symptoms were uniquely associated with elevated negative affect; only increases in depression symptoms were associated with diminished positive affect. Increases in social anxiety symptoms were associated with an elevated desire to approach others but not a desire to withdraw from others. By contrast, increases in depression symptoms were associated with a diminished desire to approach others and an elevated desire to withdraw from others. Desire for social connection may distinguish social anxiety from depression. Examining patterns of daily social motivation may enhance clinicians' ability to differentiate the difficulties that arise from social anxiety from those that arise from depression.

Abstract
Rates of child and adolescent anxiety have increased markedly over the past decade (Haidt & Twenge, 2023). Exposure-based cognitive-behavioral therapy is the gold standard in the treatment of anxious children (Hofmann et al. (2012)). However, many clinicians refrain from using exposure due to concerns about its safety, effectiveness, and ethics (Deacon et al., 2013; Whiteside et al., 2016). We propose a novel treatment approach for child anxiety composed of independence activities (IAs), which are child-directed, fun, unstructured, developmentally challenging tasks performed without parents' help. These tasks are purposely topographically unrelated to the stimuli that cause anxiety, in direct contrast to exposure therapy. Despite this dissimilarity, IAs target putative mechanisms involved in the development and maintenance of child anxiety (e.g., parental accommodation and overinvolvement, child avoidance, unhelpful thinking styles). Using a nonconcurrent multiple baseline design, this five-session treatment provided preliminary evidence of high treatment acceptability from children and parents. Medium to large improvements were reported in child anxiety and avoidance, parent and child (behavioral and cognitive) mechanisms involved in the maintenance of child anxiety, and untargeted secondary outcomes such as child happiness. Results may suggest a new treatment paradigm, which is desperately needed, given unabated increases in child and adolescent anxiety despite vast resources being directed toward the problem.

Abstract
Psychosocial treatments targeting the positive valence system (PVS) in depression and anxiety demonstrate efficacy in enhancing positive affect (PA), but response to treatment varies. We examined whether individual differences in neural activation to positive and negative valence incentive cues underlies differences in benefitting from a PVS-targeted treatment. Individuals with clinically elevated depression and/or anxiety (N = 88, ages 18 to 55) participated in one of two randomized, waitlist-controlled trials of Amplification of Positivity (AMP; NCT02330627, NCT03196544), a cognitive and behavioral intervention targeting the PVS. Participants completed a monetary incentive delay (MID) task during fMRI acquisition at baseline measuring neural activation to the possibility of gaining or losing money. Change in PA from before to after treatment was assessed using the Positive and Negative Affect Schedule. No significant associations were observed between baseline neural activation during gain anticipation and AMP-related changes in PA in regions of interest (striatum and insula) or whole-brain analyses. However, higher baseline striatal and insula activation during loss anticipation was associated with greater increases in PA post-AMP. This study provides preliminary evidence suggesting neural reactivity to negative valence cues may inform who stands to benefit most from treatments targeting the PVS.

Abstract
Among individuals living with psychotic disorders, social impairment is common, debilitating, and challenging to treat. While the roots of this impairment are undoubtedly complex, converging lines of evidence suggest that social motivation and pleasure (MAP) deficits play a key role. Yet most neuroimaging studies have focused on monetary rewards, precluding decisive inferences. Here we leveraged parallel social and monetary incentive delay fMRI paradigms to test whether blunted reactivity to social incentives in the ventral striatum-a key component of the distributed neural circuit mediating appetitive motivation and hedonic pleasure-is associated with more severe MAP symptoms in a transdiagnostic sample enriched for psychosis. To maximize ecological validity and translational relevance, we capitalized on naturalistic audiovisual clips of an established social partner expressing positive feedback. Although both paradigms robustly engaged the ventral striatum, only reactivity to social incentives was associated with clinician-rated MAP deficits. This association remained significant when controlling for other symptoms, binary diagnostic status, or ventral striatum reactivity to monetary incentives. Follow-up analyses suggested that this association predominantly reflects diminished striatal activation during the receipt of social reward. These observations provide a neurobiologically grounded framework for conceptualizing the social-anhedonia symptoms and social impairments that characterize many individuals living with psychotic disorders and underscore the need to establish targeted intervention strategies.

Abstract
Anhedonia is a reduction in enjoyment, motivation, or interest. It is common across mental health disorders and a harbinger of poor treatment outcomes. The enjoyment aspect, termed 'consummatory anhedonia', in particular poses fundamental questions about how the brain constructs rewards: what processes determine how intensely a reward is experienced? Here, we outline limitations of existing computational conceptualisations of consummatory anhedonia. We then suggest a richer reinforcement learning (RL) account of consummatory anhedonia with a reconceptualisation of subjective hedonic experience in terms of goal progress. This accounts qualitatively for the impact of stress, dysfunctional cognitions, and maladaptive beliefs on hedonic experience. The model also offers new views on the treatments for anhedonia.

Abstract
This study analyzed effects of savoring on unstudied positive mindset targets of generalized anxiety disorder (GAD) treatment (ClinicalTrials.gov: NCT05040061). 85 students with GAD were randomly assigned to one of two ecological momentary interventions (EMIs) on smartphone for seven days. The SkillJoy EMI promoted practices for savoring positive emotions. An active control EMI mirrored SkillJoy, yet did not include savoring or positive emotion. Optimism, worry, kill-joy thinking (lessening positive emotion with cognition), and prioritization of positive emotion activities and goals were assessed at pre-trial, eighth-day, post-trial, and 30th-day follow-up. Savoring was assessed pre-trial and fifth-day mid-trial. Longitudinal linear mixed models and simple slope analyses examined change between and within conditions. Bias-corrected bootstrapping path analysis examined mediation of worry change by increased savoring. SkillJoy led to significantly greater increases in both optimism and prioritizing positivity than the control from pre-trial to post-trial and pre-trial to follow-up. Both interventions significantly reduced kill-joy thinking at both timepoints with Skilljoy leading to marginally greater change at post-trial. Pre- to mid-trial increases in savoring mediated the relationships between treatment condition and reductions in worry at both post-trial and follow-up.

Abstract
Rising rates of depression on university campuses accentuate the need for specific intervention. Interventions targeting disturbances in positive affect, in particular, remain sparse, yet such deficits interfere substantially with functioning and further exacerbate or maintain negative symptoms. The current study aimed to evaluate the impact of a virtual, two-session Behavioral Activation augmented with Savoring (BA + S) intervention compared to an Emotional Awareness (EA) control group in increasing positive affect. Sixty university students with low positive affect were randomized to BA + S or EA and completed 21 days of experience-sampling of positive affect. Weekly measures of positive and negative valence symptoms were assessed at baseline, sessions one and two, and at one-week follow-up. Through a prori analyses utilizing multilevel and multivariate multilevel models, our results demonstrate that daily positive affect measured via experience-sampling significantly improved in BA + S, whereas positive affect did not change for those receiving EA, though the interaction of condition and time was not significant. Furthermore, interactions in weekly variables were significant. Increases in positive valence symptoms (affect, anhedonia, etc.) were only reported for students receiving BA + S but not EA. Negative valence symptoms (affect, depression, general distress) improved in both conditions but with superior improvements in BA + S compared to EA. BA + S shows promise for a scalable and accessible intervention to university students with clinical levels of positive and negative affect. ClinicalTrials ID: NCT05234476.

Abstract
In patients with mood disorders, negative affective biases - systematically prioritising and interpreting information negatively - are common. A translational cognitive task testing this bias has shown that depressed patients have a reduced preference for a high reward under ambiguous decision-making conditions. The precise mechanisms underscoring this bias are, however, not yet understood. We therefore developed a set of measures to probe the underlying source of the behavioural bias by testing its relationship to a participant's reward sensitivity, value sensitivity and reward learning rate. One-hundred-forty-eight participants completed three online behavioural tasks: the original ambiguous-cue decision-making task probing negative affective bias, a probabilistic reward learning task probing reward sensitivity and reward learning rate, and a gambling task probing value sensitivity. We modelled the learning task through a dynamic signal detection theory model and the gambling task through an expectation-maximisation prospect theory model. Reward sensitivity from the probabilistic reward task (β = 0.131, p = 0.024) and setting noise from the probabilistic reward task (β = -0.187, p = 0.028) both predicted the affective bias score in a logistic regression. Increased negative affective bias, at least on this specific task, may therefore be driven in part by a combination of reduced sensitivity to rewards and more variable responses.

Abstract
OBJECTIVE Novel treatments for adults with anorexia nervosa (AN) are sorely needed. Although psychological interventions have been developed for AN, none have been identified as superior to one another or nonspecific treatments. Common comorbidities (e.g., mood and anxiety disorders) are rarely targeted in AN treatments, possibly impairing long-term clinical improvement. AN is associated with reward processing dysfunctions paralleling those identified in affective disorders; however, few treatments directly target these processes. METHOD We adapted Positive Affect Treatment, a neuroscience-informed behavioral treatment developed for affective disorders, to the treatment of AN (PAT-AN). Adults with AN (N = 20) were randomized to 20 weeks of PAT-AN or waitlist to investigate the feasibility, acceptability, preliminary efficacy, and target engagement (on reward mechanisms) of PAT-AN. RESULTS PAT-AN demonstrated strong retention (100%) and acceptability ratings (M = 5.67-5.95 on a 7-point scale). BMI (p = .006) and eating disorder symptoms (p < .001) improved over PAT-AN sessions. The PAT-AN group showed medium to large pre-to-post-treatment improvements in BMI, eating disorder symptoms and impairment, depressive and anxiety symptoms, and some reward indices (ds = .56-.87); changes were largely sustained at 3-month follow-up. Waitlist showed negligible changes (ds < .20) on nearly all measures. DISCUSSION PAT-AN holds promise as an innovative treatment with capability to simultaneously improve eating disorder symptoms, affective symptoms, and underlying reward mechanisms. Findings should be interpreted cautiously due to small sample size and permitted concurrent enrollment in other treatments. Future, larger-scale research is warranted to establish the efficacy of PAT-AN. PUBLIC SIGNIFICANCE This study provided a preliminary evaluation of Positive Affect Treatment for anorexia nervosa (PAT-AN), a novel, neuroscience-informed treatment aimed at increasing rewarding life experiences outside of one's eating disorder. Initial results suggest that PAT-AN is considered acceptable and may alleviate eating disorder, depressive, and anxiety symptoms. Therefore, this study presents promising data on a treatment that may hold potential for improving the lives of individuals with this disorder.

Abstract
Reminiscence-based interventions focus on recalling autobiographical memories and reflective reasoning to develop a healthy and adaptive view of oneself and one's life. This study aimed to replicate the effects of a three-session, group-based, positive-memory version of cognitive-reminiscence therapy (CRT) on psychological resources and mental well-being and extend the findings to anticipated pleasure. The participants (N = 75, Mage = 43.7 (SD = 16.7), 60% females) were randomised to CRT or control group. Anticipated pleasure, psychological resources (schemas of positive self-esteem, self-efficacy, meaning in life, optimism), mental well-being (depression, anxiety, and stress symptoms) and theorised change processes (automatic negative thoughts, awareness of narrative identity) were assessed. Relative to the control group, the CRT group reported significantly higher anticipated pleasure (d = 0.76-0.93) and psychological resources of self-esteem, self-efficacy, and optimism (d's = 0.58-0.99) at post-CRT and follow-up, and lower depressive symptoms post-CRT and at follow-up (d = 0.56-0.67). Findings on meaning in life and negative automatic thinking were partially replicated. This study replicates findings of the effectiveness of this intervention for improving psychological resources such as self-worth, confidence and optimism and depressive symptoms, and indicates additional effects on anticipated pleasure. CRT may serve as a standalone intervention, or as an adjunct "memory booster" for interventions focused on future thinking and related anticipated reward.

Abstract
This study experimentally investigated the role of anticipated enjoyment and effort in mediating dysphoria-related deficit in activity engagement behavioural choice. Using a novel activity information processing task (about a fictional "new" Nintendo Wii sports game called "Tornado Ball"), N = 249 participants (n = 95 High Dysphoria; n = 154 Low Dysphoria) were presented information about the benefits (enjoyable features) and costs (mental and physical effort barriers) as product reviews from another player. The order of cost vs. benefit information was manipulated such that participants either heard cost information before benefit information, or vice versa. They then rated what their anticipated enjoyment and effort will be if they were to play Tornado Ball, before being given the opportunity to choose to try it themselves or not. The High Dysphoria group reported lower anticipated enjoyment (but not higher effort) relative to the Low Dysphoria group, but only when cost information was presented first. Importantly, a moderated mediation showed that the High Dysphoria group reported lower tendency to choose activity engagement (game play) as a function of having lower anticipated enjoyment, but only when cost information was presented first. The present finding indicate that reduced anticipated enjoyment may causally contribute to dysphoria-linked deficits in activity engagement behavioural choice.

Abstract
BACKGROUND Anxiety-related disorders feature elevated negative affect (NA), and in some cases, diminished positive affect (PA). It remains unclear how well extant psychotherapies for anxiety-related disorders improve PA versus NA. METHODS We systematically searched the Cochrane Central Register of Controlled Trials, PubMed, PsychInfo, and Web of Science databases. Records included studies involving (1) patients with a principal or co-principal diagnosis of at least one anxiety-related disorder (i.e., generalized anxiety, social anxiety, panic, agoraphobia, health anxiety, specific phobia, obsessive-compulsive disorder, or posttraumatic stress disorder), and (2) pre- and post-treatment PA and NA scores or a change index between pre- and post-treatment PA and NA scores. Effect sizes were calculated for meta-analyses. RESULTS Fourteen studies with 1001 adults with an anxiety-related disorder were included. Psychotherapeutic interventions included cognitive behavioral, present-centered, and imagery-based approaches. Treatments reduced NA (g = -0.90; 95%CI [-1.19, -0.61]) to a greater extent than they improved PA (g = 0.27; 95%CI [0.05, 0.59]), Z = -5.26, p < .001. The limited number of studies available precluded analyses of the relationship between changes in affect and symptoms. LIMITATIONS Results should be considered with caution given the small number and heterogeneity of included studies. CONCLUSIONS Current psychotherapeutic interventions for anxiety-related disorders may not improve PA and NA to comparable levels.

Abstract
Reward insensitivity is a potential key mechanism regarding the maintenance of depression. However, there is a lack of research examining and comparing the effectiveness of different psychological interventions in modifying reward insensitivity. This four-arm randomized controlled trial (RCT) investigated a two-week online intervention. After screening for eligibility, a total of 336 participants were randomized, and 224 participated per-protocol. Participants were assigned to either a) behavioral activation, b) mindfulness and gratitude, c) a combination of both, or d) a waitlist control condition. They received videos and implemented daily exercises. Reward sensitivity and depressive symptoms served as primary outcomes. Behavioral activation and mindfulness significantly improved depressive symptoms and reward sensitivity. However, the effects of behavioral activation were not superior. The combination treatment versus the waiting group was insignificant regarding reward insensitivity. Explorative analyses revealed that all intervention groups reduced anhedonia substantially. Our findings imply that brief online interventions with behavioral activation and mindfulness-based approaches can impact reward insensitivity, while effects for a combination were less clear. Nonetheless, our results do not allow us to infer the differential effectiveness of the interventions. There is a clear need for treatments better targeting maintaining factors of depression, such as reward insensitivity. Clinical trial registration number: NCT05402150.

The Stress Phenotyping Framework: A multidisciplinary biobehavioral approach for assessing and therapeutically targeting maladaptive stress physiology. Stress 2024; 27:2327333.

Abstract
Although dysregulated stress biology is becoming increasingly recognized as a key driver of lifelong disparities in chronic disease, we presently have no validated biomarkers of toxic stress physiology; no biological, behavioral, or cognitive treatments specifically focused on normalizing toxic stress processes; and no agreed-upon guidelines for treating stress in the clinic or evaluating the efficacy of interventions that seek to reduce toxic stress and improve human functioning. We address these critical issues by (a) systematically describing key systems and mechanisms that are dysregulated by stress; (b) summarizing indicators, biomarkers, and instruments for assessing stress response systems; and (c) highlighting therapeutic approaches that can be used to normalize stress-related biopsychosocial functioning. We also present a novel multidisciplinary Stress Phenotyping Framework that can bring stress researchers and clinicians one step closer to realizing the goal of using precision medicine-based approaches to prevent and treat stress-associated health problems.

Abstract
Psychotherapies are effective in reducing late-life depression. Yet, about half of patients remain depressed at treatment end. Advances in neuroscience can inform simplified interventions that target key brain networks impacted by depression. Behavioral activation therapies that increase social connectedness may improve social reward responsivity and alter abnormalities of the Positive Valence System (PVS). Engage & Connect is an example for a scalable and simple neuroscience-informed psychotherapy, aimed to improve PVS functions and social reward responsivity by increasing engagement in rewarding social activities. Interventions that improve social reward responsivity can be promising first-line treatments for late-life depression in the community.

Targeting positive valence systems function in children of mothers with depressive symptoms: A pilot randomized trial of an RDoC-Informed preventive intervention. Behav Res Ther 2023; 168:104384. [PMID: 37591042 PMCID: PMC10542884 DOI: 10.1016/j.brat.2023.104384] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/27/2023] [Accepted: 08/03/2023] [Indexed: 08/19/2023]
Abstract
Reduced activation of the Research Domain Criteria (RDoC) positive valence systems (PVS) is observed in high-risk (HR) children of depressed mothers and predictive of future psychopathologies. We developed a dyadic, neuroscience-informed preventive intervention, Family Promoting Positive Emotions (FPPE), designed to prevent psychopathology in HR children by targeting PVS processes. We evaluated the initial efficacy of FPPE compared to written information (WI) psychoeducation in engaging PVS-related targets and reducing perceived stress and emotional distress symptoms in HR youth. Participants included 74 children ages 8-12 years and their biological mothers reporting elevated depressive symptoms. Following random assignment, 55 dyads completed FPPE (n = 29) or WI (n = 26) and pre-post assessments of child clinical symptoms. Youth completed a reinforcement learning task and 10 days of positive affect ratings to assess PVS-related targets. Results revealed a small within-subjects increase in child daily positive affect in FPPE, but not WI. Further, FPPE resulted in reductions in mother-reported child perceived stress and symptoms of anger, anxiety, and depression with medium-to-large within-subjects effects. Intervention effects on reinforcement learning and child-rated clinical symptoms were not observed. This study suggests FPPE shows promise in enhancing positive affect and reducing the emergence of clinical symptoms in HR children. CLINICALTRIALS.GOV IDENTIFIER: NCT05223842.

J Affect Disord 2023; 336:112-119. [PMID: 37230263 PMCID: PMC10448502 DOI: 10.1016/j.jad.2023.05.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 05/09/2023] [Accepted: 05/11/2023] [Indexed: 05/27/2023]
Abstract
INTRODUCTION Accurate measurement of perinatal depression is vital. We aimed to 1) test whether a factor that measured positive affect (PA) bettered a transdiagnostic model of depression symptoms and 2) replicate the model in a second sample. METHODS We conducted secondary analyses from two samples (n's = 657 and 142) of women in treatment at perinatal psychiatric clinics. Data were derived from items from seven commonly used measures. We compared fit indices from our original factor model-one general and six specific factors derived from the Research Domain Criteria (Loss, Potential Threat, Frustrative Nonreward, and Sleep-Wakefulness) and depression literatures (Somatic and Coping)-to our novel factor model with a PA factor. The PA factor was created by recategorizing items that measured affective states with a positive valence into a new factor. Sample 1 data were split into six perinatal periods. RESULTS In both samples, the addition of a PA factor improved model fit. At least partial metric invariance was found between perinatal periods, with the exception of trimester 3 - postpartum period 1. LIMITATIONS Our measures did not operationalize PA in the same way as in the positive valence system in RDoC and we were unable to perform longitudinal analyses on our cross-validation sample. CONCLUSIONS Clinicians and researchers are encouraged to consider these findings as a template for understanding symptoms of depression in perinatal patients, which can be used to guide treatment planning and the development of more effective screening, prevention, and intervention tools to prevent deleterious outcomes.
