Reciprocal developmental pathways between future-related thinking and symptoms of adolescent depression and anxiety: A systematic review and meta-analysis of longitudinal studies.

[PMID: 39002184 DOI: 10.1016/j.cpr.2024.102465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 06/06/2024] [Accepted: 07/06/2024] [Indexed: 07/15/2024]
Abstract
Adolescence is a time when important decisions about the future are made and vulnerability to mental health problems increases. We reviewed longitudinal studies examining the reciprocal pathways between future-related thinking (hopelessness, hope, optimism/positive future expectations) and adolescent depression and anxiety symptoms. Evidence from 22 studies (N = 10,682) found that negative future-related thinking predicted subsequent depression (r = 0.27, p < .001), an effect still significant after controlling for baseline depression (r = 0.23, p < .001). Higher hopelessness (r = 0.34, p < .001), lower hope (r = 0.16, p < .001), and reduced optimism/positive future expectations (r = 0.18, p < .001) were associated with subsequently increased depressive symptoms. Negative future-related thinking also predicted later increased anxiety symptoms (r = 0.15, p = .021). Concerning the reciprocal pathway, depressive symptoms were associated with later negative future-related thinking (r = 0.32, p < .001), which remained after baseline levels of future-related thinking were controlled (r = 0.07, p = .02). There were insufficient studies to infer reciprocal links between anxiety and future-related thinking. Our analyses provided evidence of a reciprocal developmental relationship between depressive symptoms and future-related thinking, implying a negative cycle. Identifying precursors of this cycle could provide the basis for depression prevention in adolescents and promote better decision-making about the future.

Recalling and anticipating positive events to improve the positive affect and mental health of adolescents: A cluster randomized controlled trial in secondary schools. Behav Res Ther 2024; 179:104543.

Abstract
This cluster randomized controlled trial examined the effectiveness of Positive Events Training (PET), a combined group training aimed at simultaneously improving positive autobiographical memory (AM) and episodic future thinking (EFT) among adolescents (12-16 years). Delivered as a universal school-based program, PET was compared with an active (creative writing) control group (CREAT). Effects on resilience, wellbeing, positive emotions, emotional response styles towards positive emotions (savoring, dampening), anhedonia, depressive symptoms, and multiple AM and EFT indices were examined. Adolescents (NPET = 95, NCREAT = 93) completed self-report scales at baseline, post-training and two-month follow-up. Multilevel models revealed that PET led to significant improvements in certain AM and EFT skills. Moreover, a decrease in anhedonia was observed at post-training. However, this effect did not withstand correction for multiple testing. Absence of changes in the other outcomes should be interpreted within the context of the universal school-based approach and the potential limited scope for detectable changes. Exploratory analyses suggest the importance of further investigating PET's potential in addressing positive affect dysregulations in indicated samples, and exploring perceived likelihood of generated future events and dampening as potential underlying mechanisms. Study limitations and future directions to maximize the demonstrated potential of PET are discussed.

The potential of Future Event Specificity Training (FEST) to decrease anhedonia and dampening of positive emotions: A randomised controlled trial. Appl Psychol Health Well Being 2024; 16:1245-1265.

Abstract
Impaired episodic future thinking (EFT), as reflected in reduced specificity, low levels of detail and less use of mental imagery, has been associated with depressive symptomatology. The beneficial impact of Future Event Specificity Training (FEST) on impaired EFT has recently been demonstrated, as well as on anhedonia, the core symptom of depression reflecting low positive affect. The current study aimed to replicate these previous findings. In addition, this study is the first to examine the potential of FEST to reduce engagement in dampening, a maladaptive response style characterised by reducing the intensity and/or frequency of positive emotional states, which is linked to depressive symptoms and anhedonia. An RCT (FEST vs. waitlist control) was conducted in a large sample of Dutch-speaking undergraduate students (N = 155). In line with prior research, FEST resulted in significant improvements in EFT features. However, likely related to limited room for change detection, no significant changes were found in anhedonia and dampening. In the light of the positive impact of FEST on several EFT features, future studies should address methodological issues to create optimal conditions for potential change detection. Finally, further examination of the proposed theoretical change mechanisms aimed to reduce anhedonia and dampening is warranted.

Abstract
Many people with schizophrenia spectrum disorders (SSDs) experience profound amotivation, which is strongly related to anticipatory anhedonia. Yet, the neuropsychological fundamentals of anticipatory anhedonia and amotivation are barely understood, resulting in a lack of effective treatments for these patients. Aberrancies in positive mental imagery may interfere with the anticipation of pleasure and could thus explain anticipatory anhedonia and amotivation. However, the nature of mental imagery and its relationship with amotivational psychopathology in SSD is largely unknown. In this preregistered study, we therefore examined mental imagery characteristics and their relation to anticipatory anhedonia, amotivation, and daily life activity in SSD. TheN = 86 participants included individuals with SSD (n = 43) and demographically matched healthy controls (n = 43). Mental imagery, anticipatory pleasure, amotivation, and activity engagement were assessed with structured interviews and self-report questionnaires. Ecological momentary assessment was used to measure state anticipatory pleasure and activity engagement in daily life (n = 81). Compared to the control group, the SSD group showed comparable quantity, but less vividness of mental imagery. Reduced vividness of mental imagery in SSD was significantly associated with higher anticipatory anhedonia, amotivation, and low activity engagement in cross-sectional and prospective analyses. Reduced mental imagery vividness may cause a lack of internal incentive to seek pleasurable experiences and could explain amotivation. Interventions aiming to improve mental imagery vividness and related anticipatory pleasure responses in SSD may be effective in targeting amotivation.

Abstract
BACKGROUND This study aimed to delineate the interplay between depression, hopelessness, and episodic future thinking (EFT), focusing on cognitive biases towards negative future thinking that are central to depressive symptomatically. METHODS A Japanese university student was utilized to scrutinize divergences in EFT across groups stratified by varying degrees of depression and hopelessness. The research leveraged a modified future thinking task (FTT), the Beck Hopelessness Scale, and the Beck Depression Inventory-II to gauge participants' levels of hopelessness and depressive symptoms. RESULTS Consistent with prior research, the non-depressed group showed a reduction in positive EFT, reinforcing the idea that diminished positive future thinking is a hallmark of depressive conditions, even in the absence of a clinical diagnosis. Moreover, individuals with comorbid depression and elevated hopelessness demonstrated a significant decrease in positive EFT and an increase in negative EFT, substantiating a distinctive cognitive profile for this subgroup. This finding suggests that the presence of hopelessness exacerbates the negative cognitive biases associated with depression. CONCLUSIONS The study emphasizes the importance of considering hopelessness as an independent construct when assessing EFT in clinical contexts. The pronounced impact of hopelessness on future thinking in those with depression suggests that targeted interventions, such as future-directed therapy (FDT), may be particularly effective for individuals with hopelessness depression by focusing on modifying negative future thinking patterns and enhancing life quality.

Abstract
Current research indicates that anxiety disorders and elevated levels of trait anxiety are associated with biases and impairments when thinking of personally relevant future events, that is, future thinking. However, to date, little research has been conducted into how people with symptoms of clinical anxiety perceive the functions of future thinking. The current study presents a cross-sectional survey comparing individuals with elevated symptoms of generalized anxiety disorder (GAD) and related functional impact (N = 51, 43.1% female, Mage = 33.1, SD = 10.2) matched on age and gender with individuals with no clinically significant symptoms of GAD (N = 51, 43.1% female, Mage = 33.3, SD = 10.1) on self-reported functions of future thinking and a battery of items assessing the phenomenological characteristics. The results indicated various significant differences in the perceived functions of future thinking and its phenomenological characteristics in those with elevated GAD symptoms. Broadly, they indicate more frequent future thinking and more commonly for self-distraction or processing negatively valenced future events, and generally less adaptive mental representations that support current thinking on the psychopathological process of increased worry, anxious arousal and maladaptive cognition in clinical anxiety symptoms.

Abstract
Previous research demonstrating that positive episodic simulation enhances future expectancies has relied on explicit expectancy measures. The current study investigated the effects of episodic simulation on implicit expectancies. Using the Future Thinking Implicit Relational Assessment Procedure (FT-IRAP), participants made true/false decisions to indicate whether or not they expected positive/negative outcomes after adopting orientations consistent or inconsistent with an optimistic disposition. The outcome measure, DIRAP, was based on response time differences between consistent and inconsistent blocks. Participants then engaged in either positive simulation training, in which they imagined positive future events, or a neutral visualisation task before repeating the FT-IRAP twice following 10-minute intervals. Positive simulation training increased DIRAP scores for don't-expect-negative trials-boosting participants' readiness to affirm that negative events were unlikely to happen to them. Although findings did not generalise across all trial types, they show potential for positive simulation training to enhance implicit future expectancies.

Abstract
OBJECTIVE Impairments in episodic future thinking and anticipatory pleasure were noted to explain the depressive symptoms in adults however similar studies are not there in adolescents. This study examined whether there are impairments in episodic future thinking and anticipatory pleasure in clinically-depressed adolescents as compared to non-depressed adolescents, and their association with depression when controlled for executive functions and anxiety symptoms among the depressed adolescents. METHODS The study included 29 adolescents with major depression and 29 adolescents from local schools through convenient sampling technique. All the participants were assessed with standardized measures of depression and anxiety, episodic future thinking, anticipatory pleasure and executive functioning. RESULTS Depressed adolescents significantly differed from the non-depressed adolescents in autobiographical memory specificity, anticipatory pleasure, and specific dimensions of executive functions. The ANCOVAs indicated executive function slightly attenuated group differences on future specificity which were still non-significant (all p's > .05). For memory specificity and for anticipatory pleasure, group differences were still significant at p < .05 level. CONCLUSION Adolescents with major depressive episode may display similar, but less pronounced, impairments in future thinking than what is previously reported in adults. Though, autobiographical specificity is prominent. The deficits are attributable to depression than executive functioning deficits.

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
Negative bias in prospection may play a crucial role in driving and maintaining depression. Recent research suggests abnormal activation and functional connectivity in regions of the default mode network (DMN) during future event generation in depressed individuals. However, the neural dynamics during prospection in these individuals remain unknown. To capture network dynamics at high temporal resolution, we employed electroencephalogram (EEG) microstate analysis. We examined microstate properties during both positive and negative prospection in 35 individuals with subthreshold depression (SD) and 35 controls. We identified similar sets of four canonical microstates (A-D) across groups and conditions. Source analysis indicated that each microstate map partially overlapped with a subsystem of the DMN (A: verbal; B: visual-spatial; C: self-referential; and D: modulation). Notably, alterations in EEG microstates were primarily observed in negative prospection of individuals with SD. Specifically, when generating negative future events, the coverage, occurrence, and duration of microstate A increased, while the coverage and duration of microstates B and D decreased in the SD group compared to controls. Furthermore, we observed altered transitions, particularly involving microstate C, during negative prospection in the SD group. These altered dynamics suggest dysconnectivity between subsystems of the DMN during negative prospection in individuals with SD. In conclusion, we provide novel insights into the neural mechanisms of negative bias in depression. These alterations could serve as specific markers for depression and potential targets for future interventions.

Abstract
Background Many stress-related mental health problems, like depression and anxiety, emerge during adolescence, with some recent studies suggesting numbers are increasing. One possible way to reduce adolescents' vulnerability to stress-related mental health problems is to increase their resilience by training them in recalling specific positive memories and anticipating specific positive future events. Therefore, an innovative combi-training (called Positive Events Training; PET) was developed, focusing on the enhancement of the specificity of both past and future positive autobiographical events in adolescents. Its effects on adolescents' resilience and mental wellbeing will be examined. Methods A cluster randomized controlled trial with a 2 (condition) × 3 (time-point) factorial design was conducted. Classes of adolescents were randomized to either a PET program (intervention) or a CREAtive writing Training (CREAT) program (active control). Both trainings consisted of four sessions of 50 min (one session, weekly, for four consecutive weeks) and were delivered in schools. Before (pre-training, T1), immediately after (post-training, T2), and 2 months after the training (follow-up, T3), participants completed a series of self-report questionnaires. Primary outcomes are resilience and mental wellbeing. Secondary outcomes are positive affect, positive affect regulation and anhedonia. CONSORT criteria for conducting and reporting RCTs will be used. Ethics and dissemination Ethical approval was obtained from the Social and Societal Ethics Committee (SMEC) and the study has been preregistered on Open Science Framework (OSF) and ClinicalTrials.gov (Trial registration number: NCT05757180). We plan to develop a free, online, web-based self-directed PET protocol for teachers if the study provides evidence for the effectiveness of the PET program in increasing adolescents' resilience and mental wellbeing, so teachers can deliver the program to future students without the need of professional external trainers.

Abstract
Voluntary and involuntary mental time travel can take the form of episodic memory, episodic future thinking, and episodic counterfactual thinking. This study uses an individual-differences approach to understand why people engage in these forms of mental time travel. The individual-differences variables include trait-level personality, boredom proneness, depression, anxiety, stress, emotion regulation, mindfulness, mind-wandering, positive and negative affect, rumination, optimism, thinking styles, and time perspective. Across two studies, our results indicate that individual differences underlie these forms of mental time travel. The most unique, episodic counterfactual thinking, was alone positively correlated with negative emotionality and negatively correlated with optimism. We also observe differences as a function of voluntariness and discuss these findings in relation to the cognitively demanding nature of constructing future and counterfactual thoughts. We discuss the importance of distinguishing voluntary from involuntary thinking and assessing episodic counterfactual thinking in relation to episodic memory and episodic future thinking.

Abstract
Future-oriented cognition plays a manifold role for adults' mental health. The present study aimed to investigate the relationship between future-oriented cognition and mental health in N = 191 children aged between 3 and 7 years. Parents completed an online-questionnaire including children's future-oriented cognition (e.g., episodic foresight; Children Future Thinking Questionnaire; CFTQ), children's mental health problems (Strengths and Difficulties Questionnaire; SDQ), and wellbeing (Parent-rated Life Orientation Test of children; PLOT and Positive-Mental-Health Scale; PMH). More externalizing problems (especially hyperactivity) related to lower future-oriented cognition. For mental wellbeing, higher levels of optimism were associated with higher episodic foresight. Future-oriented cognition increased with age cross-sectionally. This increase was flatter at higher levels of wellbeing (indicated by lower pessimism). Results are discussed considering findings on the role of future-oriented cognition for mental health in adults and adolescents. Suggestions for future work are presented regarding the direction of the observed links and underlying mechanisms.

Abstract
Negative or stressful life events are robust risk factors for depression and anxiety. Less attention has been paid to positive aspects of events and whether positivity buffers the impact of negative aspects of events. The present study examined positivity and negativity of interpersonal and non-interpersonal episodic life events in predicting anxiety and depressive symptoms in a sample of 373 young adults. Regressions tested main and interactive effects of positivity and negativity ratings of events in predicting symptom factors (Fears, Anhedonia-Apprehension (AA), General Distress (GD)) relevant to anxiety and depression. A significant interaction demonstrated that positivity protected against high levels of negativity of non-interpersonal events in predicting GD. A main effect of interpersonal negativity predicting higher AA was observed. Results for Fears were non-significant. Findings suggest that positivity of life events may buffer against negativity in predicting symptoms shared between anxiety and depression.

Abstract
Recalling personal past events and imagining personal future events are closely linked, yet also show differences. It has been claimed that episodic future thinking produces stronger intensity of in-the-moment affect than does recalling episodic memories [Schubert, T., Eloo, R., Scharfen, J., & Morina, N. (2020). How imagining personal future scenarios influences affect: Systematic review and meta-analysis. Clinical Psychology Review, 75, 101811. https://doi.org/10.1016/j.cpr.2019.101811]. In contrast, the literature indicates that memories are experienced more vividly than are episodic future thoughts, a quality that would be expected to produce a stronger rather than a weaker affective response. In this systematic review and meta-analysis, we examined (a) the intensity of affect, (b) the vividness and (c) the valence of emotion experienced in response to remembering personal past events compared to imagining personal future events. Sixteen studies with a combined sample of 1735 met criteria for inclusion. Remembered past events were experienced more vividly than imagined future events but there was no difference between the two types of representations on emotional intensity. Imagined future events were associated with more positive emotion than memories. Future research could examine factors responsible for the equivalent strength of emotional response in memories and future-thinking despite their differences in vividness.

Abstract
In this paper, I tentatively answer 50 questions sampled from a pool of over 10,000 weekly questions formulated by students in a course entitled "The Self". The questions pertain to various key topics related to self-processes, such as self-awareness, self-knowledge, self-regulation, self-talk, self-esteem, and self-regulation. The students' weekly questions and their answers highlight what is currently known about the self. Answers to the student questions also allow for the identification of some recurrent lessons about the self. Some of these lessons include: all self-processes are interconnected (e.g., prospection depends on autobiography), self-terms must be properly defined (e.g., self-rumination and worry are not the same), inner speech plays an important role in self-processes, controversies are numerous (are animals self-aware?), measurement issues abound (e.g., self-recognition as an operationalization of self-awareness), deficits in some self-processes can have devastating effects (e.g., self-regulatory deficits may lead to financial problems), and there are lots of unknowns about the self (e.g., gender differences in Theory-of-Mind).

Abstract
Background Positive prospective mental imagery plays an important role in mental well-being, and depressive symptoms have been associated with difficulties in generating positive prospective mental images (PPMIs). We used a mobile app to gather PPMIs generated by young adults during the COVID-19 pandemic and analyzed content, characteristics, and associations with depressive symptoms. Methods This is a secondary analysis of a randomized controlled trial with 95 healthy young adults allocated into two groups (intervention and control). Participants used the mobile app decreasing mental health symptoms for seven consecutive days. Fifty participants in the intervention group reported PPMIs at least three times per day using a mobile app inducing PPMI generation. We categorized entries into themes and applied moderation models to investigate associations between PPMI characteristics and depressive symptoms. Results We distinguished 25 PPMI themes. The most frequent were related to consuming food and drinks, watching TV/streaming platforms, and doing sports. Vividness and ease of generation of PPMIs, but not their anticipation, pleasure intensity or number of engagements with the app were associated with fewer depressive symptoms. Conclusions We identified PPMI themes in young adults and found significant negative associations between depressive symptoms and vividness and generation ease of PPMIs. These results may inform prevention and intervention science, including the design of personalized interventions. We discuss implications for future studies and treatment development for individuals experiencing diminished PPMI.

Abstract
BACKGROUND The nucleus accumbens (Nac) is a crucial brain region in the pathophysiology of major depressive disorder (MDD) patients with anhedonia. However, the relationship between the functional imaging characteristics of Nac subregions and anhedonia remains unclear. Thus, this study aimed to investigate the role of resting-state functional connectivity (rsFC) of the Nac subregions between MDD and anhedonia. METHODS We performed resting-state functional magnetic resonance imaging (fMRI) to measure the rsFC of Nac subregions in 55 MDD patients and 30 healthy controls (HCs). A two-sample t test was performed to determine the brain regions with varying rsFC among Nac subregions between groups. Then, correlation analyses were carried out to investigate the relationships between the aberrant rsFC of Nac subregions and the severity of anhedonia. Furthermore, we constructed a mediation model to explain the role of the aberrant rsFC of Nac subregions between MDD and the severity of anhedonia. RESULTS Compared with the HC group, decreased rsFC of Nac subregions with regions of the prefrontal cortex, insula, lingual gyrus, and visual association cortex was observed in MDD patients. In the MDD group, the rsFC of the right Nac shell-like subregions with the middle frontal gyrus (MFG)/superior frontal gyrus (SFG) was correlated with consummatory anhedonia, and the rsFC of the Nac core-like subdivisions with the inferior frontal gyrus (IFG)/insula and lingual gyrus/visual association cortex was correlated with anticipatory anhedonia. More importantly, the functional alterations in the Nac subregions mediated the association between anhedonia and depression. CONCLUSIONS The present findings suggest that the functional alteration of the Nac subregions mediates the association between MDD and anhedonia, which provides evidence for the hypothesis that MDD patients have neurobiological underpinnings of reward systems that differ from those of HCs.

Abstract
Mental simulations of positive future events increase their detail/vividness and plausibility, with effects on cognitive-affective processes such as anticipated and anticipatory pleasure. More recently, spatial details have been distinguished as important in increasing detail and elaborating mental scene construction. Building on this research, this study (N = 54; M age = 26.9) compared simulations of positive, self-relevant future events spatial details (i.e. people, objects, sequences of actions) with simulations focused on content details. Cross-sectionally at baseline, spatial details uniquely predicted phenomenological characteristics of future events, including anticipatory pleasure. The guided simulations increased detail and vividness, mental imagery, and pre-experiencing in both conditions. The content simulation condition did not increase content details relative to the spatial simulation condition, however, the inverse was true. Relatedly, overall detail and vividness were higher in the spatial condition, as was perceived control. The findings are discussed in relation to future thinking and mental health.

Abstract
"Prospection" refers to the ability to mentally simulate one's future episodes. Negative bias in prospection, which includes both reduced positivity and enhanced negativity, is considered to be closely related to the development and maintenance of depression. However, there is a relative paucity of measures that adequately assess negative bias in prospection in depressed people. The current study developed and initially validated the Negative Bias in Prospection Scale (NBPS) using a nonclinical sample (n = 959). The validity and reliability of the NBPS were investigated in several ways. Results suggested the 14 NBPS items loaded onto three factors, namely the "Increased negativity," the "Reduced positivity," and the "Overgeneralization." The NBPS demonstrated decent internal consistency and test-retest reliability. Further, the NBPS was strongly associated with severity of depressive symptoms. Moreover, the NBPS was correlated in a theoretically meaningful way with other measures of future-oriented cognitions or negative biases. In conclusion, the NBPS has promising preliminary psychometric properties. It will be an efficient tool for exploring dysfunctional prospection in depression and provides a novel measure for mechanism of change in prospection-based interventions.

Abstract
Abstract
Background
Improving future thinking, such as characteristics of specificity, detail, and use of mental imagery, may be one means to reduce anhedonia, particularly in a Major Depressive Episode (MDE) in which future thinking is impaired. The current study aimed to test this using a validated program, Future Event Specificity Training (FEST).
Methods
Participants (N = 177; 80.8% women; M age = 43.7, SD = 11.8) with a current depressive episode with anhedonia and high symptom severity were randomized to FEST or no FEST. Future thinking, anhedonia-related variables, and other clinical outcomes were assessed at baseline, one- and three-month follow-up.
Results
Relative to the control group, FEST was associated with significantly improved future thinking characteristics, a reduced likelihood of anhedonia (35.1% vs. 61.1%, p = .015), improvements on other anhedonia-related variables such as anticipatory (d = 0.63, p = .004) and anticipated pleasure for future events (d = 0.77, p < .001), and desirable clinical outcomes such as less people meeting criteria for an MDE (37.8% vs. 64.8%, p = .011), higher behavioural activation (d = 0.71, p = .001) and improved global functioning (d = 0.52, p = .017). Changes in future thinking were found to mediate the effect of FEST on anhedonia.
Conclusion
The quality of future thinking can be enhanced in Major Depression, and this leads to a substantially reduced likelihood of anhedonia, other significant clinical effects, and functional gains.

Abstract
In recent years, episodic future thinking (EFT) has emerged as a promising behavioral intervention to reduce delay discounting or maladaptive health behaviors; however, considerable methodological heterogeneity in methods for eliciting engagement in EFT has been observed in prior research. In this narrative review, we briefly describe methods for generating EFT cues, the content of EFT cues, common control conditions for experiments utilizing EFT, and considerations for cue delivery and implementation. Where possible, we make suggestions for current best practices in each category while identifying gaps in knowledge and potential areas of future research. Finally, we conclude by using the NIH Stage model to better frame the current state of the literature on EFT and propose gaps to be addressed if EFT is to be both an efficacious and effective behavioral intervention.

Abstract
Anhedonia, a loss of interest or pleasure in activities, is a transdiagnostic symptom that characterizes many individuals suffering from depression and anxiety. Most psychological interventions are designed to decrease negative affect rather than increase positive affect, and are largely ineffective for reducing anhedonia. More recently, affective neuroscience has been leveraged to inform treatments for anhedonia by targeting aspects of the Positive Valence Systems, including impairments in reward anticipation, reward responsiveness, and reward learning. In this chapter, we review the efficacy of treatments and, when possible, highlight links to reward constructs. Augmented behavioral approaches and targeted cognitive interventions designed to target reward anticipation, responsiveness, and learning show preliminary efficacy in reducing anhedonia, while there is a relative lack of treatments that target positive emotion regulation and reward devaluation. In addition to developing treatments that address these targets, the field will benefit from establishing standardized measurement of anhedonia across units of analysis, mapping mechanisms of change onto aspects of reward processing, and examining anhedonia outcomes in the long-term.

Abstract
Episodic specificity inductions, involving brief training in recollecting episodic details, have been shown to improve subsequent performance on tasks involving remembering the past, imagining the future and problem solving. The current study examined if specificity inductions targeting self-referential past or future episodic thinking would have dissociable effects on generating past and future episodic detail and problem solving. Sixty-three participants were randomised to either a past self-referential or future self-referential episodic induction. All participants also completed a control task. Participants randomised to the self-referential future thinking induction generated more episodic details on past and future narrative tasks compared to a control task, whereas participants randomised to a self-referential past thinking induction showed similar performance to the control task. When examining within-group performance of participants randomised to the past or future induction, we found some evidence of dissociable effects of inductions on narrative generation tasks, but not on problem solving outcomes. Our findings suggest that self-referential inductions may be useful for increasing episodic specificity, but that the temporal distance and direction of the induction matters. We discuss our results in the context of the potential clinical utility of this approach for populations vulnerable to autobiographical memory disruption.

Abstract
Preliminary evidence suggests mental imagery-based episodic simulation of planned reward activities may amplify motivation and promote greater behavioural engagement, particularly for activities with high motivational barriers (Renner, Murphy, Ji, Manly, & Holmes, 2019). This study conducted a conceptual replication and extension of Renner et al. (2019). N = 81 first-year university students self-selected and scheduled two reward activities (one hedonic, one mastery) for the following week before being randomly allocated to either an Imagery-Experiential elaboration condition (n = 27), a Verbal-Reasoning elaboration condition (n = 28), or a Scheduling-only Control condition (n = 26). Following the lab session, all participants received standardized daily prompts to complete daily activity diaries online for seven days. The Imagery-Experiential condition reported greater increases in anticipatory pleasure (state mood), anticipated pleasure, and self-reported motivation compared to the Scheduling-only Control condition, and greater increases in anticipatory pleasure (state mood), but not anticipated pleasure or motivation, relative to the Verbal-Reasoning condition. Consistent with Renner et al. (2019), the Imagery-Experiential condition, but not the Verbal-Reasoning condition, reported more frequent engagement in high motivational barrier activities than the Scheduling-only Control condition. Exploratory mediational analyses suggested that mental imagery may exert unique motivational impacts via its impact on anticipatory pleasure (state mood), although indirect effects were only observed for self-reported motivation change in the lab, with real world behavioural effects falling short of statistical significance.

Prospective mental imagery in depression: Impact on reward processing and reward-motivated behaviour. CLINICAL PSYCHOLOGY IN EUROPE 2021; 3:e3013.

Abstract
Background Mental imagery has long been part of cognitive behavioural therapies. More recently, a resurgence of interest has emerged for prospective mental imagery, i.e. future-directed imagery-based thought, and its relation to reward processing, motivation and behaviour in the context of depression. Method We conducted a selective review on the role of prospective mental imagery and its impact on reward processing and reward-motivated behaviour in depression. Results Based on the current literature, we propose a conceptual mechanistic model of prospective mental imagery. Prospective mental imagery of engaging in positive activities can increase reward anticipation and reward motivation, which can transfer to increased engagement in reward-motivated behaviour and more experiences of reward, thereby decreasing depressive symptoms. We suggest directions for future research using multimodal assessments to measure the impact of prospective mental imagery from its basic functioning in the lab to real-world and clinical implementation. Conclusion Prospective mental imagery has the potential to improve treatment for depression where the aim is to increase reward-motivated behaviours. Future research should investigate how exactly and for whom prospective mental imagery works. This review provides a selected update of the literature on prospective mental imagery. Prospective mental imagery might decrease depression via reward processing and reward-motivated behaviours. Suggestions for future research to investigate these hypotheses are provided.

Abstract
Impairments in retrieving event-level, specific autobiographical memories, termed overgeneral memory (OGM), are recognised as a feature of clinical depression. A previous meta-analytic review assessing how OGM predicts the course of subsequent depressive symptoms showed small effects for correlations and regression analyses when baseline depressive symptoms were controlled for. We aimed to update this study and examine whether their findings replicate given the decade of research that has been published since. A systematic literature review using the same eligibility criteria as the previous meta-analysis led to a doubling of eligible studies (32 v. 15). The results provided more precise estimates of effect sizes, and largely support the finding that OGM predicts the course of depressive symptoms. The effects were generally small, but significantly larger among clinical samples, compared to studies with non-clinical samples. There was some evidence that higher age was associated with stronger effects, and longer follow-up was associated with weaker effects. The findings on other moderating variables that were analysed were mixed. Continued research into this modifiable cognitive process may help to provide an avenue to better understand and treat highly prevalent and impactful depressive disorders.

Abstract
The Temporal Experience of Pleasure Scale (TEPS) is a multidimensional self-report measure that has been used to improve understanding of anticipation ("wanting") and consummation ("liking") of reward. The TEPS has been used to assess anhedonia in clinical depression, but its factor structure has not yet been confirmed in this population. This seems important given mixed findings on the model fit and factor structure of the TEPS in other clinical and community samples. To remedy this, the current study used confirmatory factor analysis to test models of the TEPS items across three studies: (a) in adults with major depression (n = 334), (b) in youth with major depression (n = 305), and (c) in a community sample (n = 320). In summary, the model fit of the two-factor TEPS scales was adequate in depressed and community Australian samples. Nevertheless, some items may require removal or revision based on cultural preferences for pleasurable experiences.

Abstract
BACKGROUND The nucleus accumbens (NAc) is an important region in reward circuit that has been linked with anhedonia, which is a characteristic symptom of major depressive disorder (MDD). However, the relationship between the functional connectivity of the NAc subregions and anhedonia in MDD patients remains unclear. METHODS We acquired resting-state functional magnetic resonance imaging (fMRI) scans from fifty-one subjects (23 MDD patients and 28 healthy controls). We assessed subjects' trait anhedonia with the Temporal Experience of Pleasure Scale (TEPS). Seed-based resting-state functional connectivity (rsFC) was conducted for each of the NAc subregions (bilateral core-like and shell-like subdivisions) separately to identify regions whose rsFCs with the NAc subregions were altered in the MDD patients and regions whose rsFCs with the NAc subregions showed different correlates with anhedonia between the MDD patients and the healthy controls. RESULTS Compared with the health controls, the MDD patients showed decreased rsFCs of the right NAc core-like subdivision with the left mid-anterior orbital prefrontal cortex and the right inferior parietal lobe as well as decreased rsFC of the left NAc core-like subdivision with the right middle frontal gyrus. Moreover, the severity of anhedonia by the group interaction was significant for the rsFC of the right NAc shell-like subdivision with the subgenual/pregenual anterior cingulate cortex and the rsFC of the right NAc core-like subdivision with the precuneus. CONCLUSIONS We found that the neural correlates of anhedonia indicated by the rsFCs of the NAc subregions were modulated by depression. The modulation effect was regionally-dependent. These findings enrich our understanding of the neural basis of anhedonia in MDD.

Abstract
Episodic future thinking (EFT) has been suggested to underlie anticipatory pleasure (AP), itself known to play a crucial role in social functioning (SF). Both AP and SF are impaired in various clinical populations, including autism spectrum disorders (ASD) and 22q11.2 deletion syndrome (22q11DS). Therefore, the relationship between EFT, AP and SF was investigated, as well as the potential role of projecting oneself in a social vs. non-social context. Seventy-seven participants [24 with 22q11DS, 20 with ASD, 33 typically developing controls (TDs)] (aged 12–25) were included. They were assessed with a future thinking task in which they were asked to recall a memory and produce a likely event. Narratives were rated based of specificity, richness and imaginability. Participants completed questionnaires assessing AP and SF. Narratives from ASD and 22q11DS participants were rated as less vivid compared to TDs. However, the characteristics of the narratives differed between ASD and 22q11DS participants in terms of specificity and level of details, as well as in reaction to social condition. Moreover, correlations were found between AP and EFT in both ASD and 22q11DS participants, and between SF and EFT in ASD participants. These results point towards impairments in EFT in both ASD and 22q11DS participants but with a specific profile in each condition. The observed associations between EFT and AP suggest that decreased autonoetic consciousness might underlie AP impairments. In ASD individuals, the association between SF and EFT highlights the need to better characterize EFT since EFT could be another mechanism contributing to social difficulties.

Abstract
AbstractMental imagery has a long history in the science and practice of cognitive behaviour therapy (CBT), stemming from both behavioural and cognitive traditions. The past decade or so has seen a marked increase in both scientific and clinical interest in mental imagery, from basic questions about the processes underpinning mental imagery and its roles in everyday healthy functioning, to clinical questions about how dysfunctions in mental imagery can cause distress and impairment, and how mental imagery can be used within CBT to effect therapeutic change. This article reflects on the current state of mental imagery in the science and practice of CBT, in the context of past developments and with a view to future challenges and opportunities. An ongoing interplay between the various strands of imagery research and the many clinical innovations in this area is recommended in order to realise the full therapeutic potential of mental imagery in CBT.

Abstract
Episodic simulation is the construction of a mental representation of a specific autobiographical future event. Episodic simulation has increasingly been studied in psychiatric populations. Here we 1) review evidence indicating that episodic simulation is compromised in patients with depression, anxiety, schizophrenia, bipolar disorder, and PTSD; and 2) consider several potential cognitive mechanisms of episodic simulation in psychiatric populations: episodic retrieval, scene construction, mental imagery, components of the CaRFAX model (i.e., capture and rumination, functional avoidance, and executive functioning), and narrative style. We evaluate evidence regarding these mechanisms across psychiatric populations, and identify areas of future research. Understanding the factors that contribute to episodic simulation impairment in psychiatric populations may lead to targeted and effective treatment approaches.

Abstract
Prospection (mentally simulating future events) generates emotionally-charged mental images that guide social decision-making. Positive and negative social expectancies-imagining new social interactions to be rewarding versus threatening-are core components of social approach and avoidance motivation, respectively. Interindividual differences in such positive and negative future-related cognitions may be underpinned by distinct neuroanatomical substrates. Here, we asked 100 healthy adults to vividly imagine themselves in a novel self-relevant event that was ambiguous with regards to possible social acceptance or rejection. During this task we measured participants' expectancies for social reward (anticipated feelings of social connection) or threat (anticipated feelings of rejection). On a separate day they underwent structural MRI; voxel-based morphometry was used to explore the relation between social reward and threat expectancies and regional grey matter volumes (rGMV). Increased rGMV in key default-network regions involved in prospection, socio-emotional cognition, and subjective valuation, including ventromedial prefrontal cortex, correlated with both higher social reward and lower social threat expectancies. In contrast, social threat expectancies uniquely correlated with rGMV of regions involved in social attention (posterior superior temporal sulcus, pSTS) and interoception (somatosensory cortex). These findings provide novel insight into the neurobiology of future-oriented cognitive-affective processes critical to adaptive social functioning.

Abstract
The Wistar Kyoto (WKY) rat has been proposed as a model of depression-like symptoms. However, anhedonia-a reduction in the response to normatively rewarding events-as a central depression symptom has yet to be fully assessed in this model. We compared WKY rats and Wistar controls, with stress-susceptibility examined by applying mild unpredictable stress to a subset of each group. Anhedonia-like behavior was assessed using microstructural analysis of licking behavior, where mean lick cluster size reflects hedonic responses. This was combined with tests of anticipatory contrast, where the consumption of a moderately palatable solution (4% sucrose) is suppressed in anticipation of a more palatable solution (32% sucrose). WKY rats displayed greatly attenuated hedonic reactions to sucrose overall, although their reactions retained some sensitivity to differences in sucrose concentration. They displayed normal reductions in consumption in anticipatory contrast, although the effect of contrast on hedonic reactions was greatly blunted. Mild stress produced overall reductions in sucrose consumption, but this was not exacerbated in WKY rats. Moreover, mild stress did not affect hedonic reactions or the effects of contrast. These results confirm that the WKY substrain expresses a direct behavioral analog of anhedonia, which may have utility for increasing mechanistic understanding of depression symptoms.

Abstract
A range of psychiatric disorders are characterised by impairments in episodic future thinking (EFT), and particularly simulating specific, spatiotemporally-located future events. No study has examined whether training can lead to sustained improvement in specific EFT. In this study, participants (N = 60; M age = 31, SD = 13.2) were randomized to a two-session, group-based future thinking program (Future Specificity Training; FeST) or wait-list. At follow-up the training group, relative to wait-list, showed large, statistically-significant improvements in the ability to mentally simulate specific EFT (d = .82), increases in detail (d = 1.32), use of mental imagery (d = 1.32), anticipated (d = 1.78) and anticipatory pleasure (d = 1.07), perceived control (d = 1.20), and likelihood of occurrence (d = 1.09). Some effects were also observed on positive, generalised future self-states. In the context of inherent limitations of subjective reporting in trials, this study provides evidence that EFT specificity can be enhanced, and the effects of FeST indicate a possible avenue to disrupt psychopathological processes.
