“…As such, future investigations should quantify individual differences in state and trait anxious symptoms. Relatedly, although our investigation replicates the findings of others regarding future thinking impairments in schizophrenia, it remains possible that these findings are not specific to schizophrenia and are instead a function of the experience of mental illness or are transdiagnostic in nature (Hallford et al ., ). Future research in this area should compare participants with diagnoses of schizophrenia to participants with other diagnoses associated with future thinking impairments to examine the specificity of these impairments.…”

“…For example, schizophrenia seems to be related to reduced anticipatory pleasure, but this may be accounted for by impairments in cognitive processing abilities (Hallford & Sharma, ). Further investigation of future thinking abilities in people with schizophrenia is warranted given the important function that pre‐experiencing future events plays in providing people with a sense of hope and enabling them to prepare for challenges that they might encounter in their environment (Hallford et al ., ).…”

“…This analysis additionally examined the contribution of depressive symptoms to future thinking as such symptoms are a common feature of schizophrenia (Gozdzik‐Zelazny, Borecki, & Pokorski, ; Ricarte, Hernández, Latorre, Danion, & Berna, ; Zisook et al ., ) and have elsewhere been associated with impaired autobiographical memory (Van Vreeswijk & De Wilde, ) and future thinking (Hallford et al ., ). Several within‐group correlational analyses were also performed amongst participants with schizophrenia in order to examine whether the characteristics of these participants were associated with their future thinking abilities.…”

“…The mental simulation of future events is critical for motivation, problem solving, emotion regulation, and identity‐continuity across time (D'Argembeau, Renaud, & Van Der Linden, ). Schizophrenia is consistently related to impairments in future thinking (Hallford, Austin, Takano, & Raes, ), yet there are mixed findings regarding the nature of these impairments and their association with other cognitive processes. For example, schizophrenia seems to be related to reduced anticipatory pleasure, but this may be accounted for by impairments in cognitive processing abilities (Hallford & Sharma, ).…”

Objectives. The ability to think about future events serves a range of important functions. People with schizophrenia show impairments in future thinking. However, whether these impairments are specific to positive or negative events and to what extent they are associated with impairments in verbal fluency and autobiographical memory remains poorly understood.Methods. People with schizophrenia (n = 93) and people without psychiatric diagnoses (n = 111) were asked to generate future events and retrieve past autobiographical events and they also completed a test of verbal fluency. Participants also completed questionnaire measures of the positive and negative dimensions of schizophrenia and depression symptoms.Results. People with schizophrenia generated significantly fewer positive and negative future events than controls. In a linear regression, the interaction between diagnosis and autobiographical memory retrieval explained a significant amount of variance in the number of future events that participants generated even when accounting for symptoms and verbal fluency. Past and future thinking abilities were correlated in controls but not in people with schizophrenia.Conclusions. People with schizophrenia may not rely on autobiographical content to imagine the future and may rely instead on semantic processes. Interventions that improve past and future thinking amongst people with schizophrenia are warranted. Practitioner pointsCompared to control participants, people with schizophrenia have marked difficulty generating possible, positive and negative, future events.

“…Activating and maintaining cognitive representations of experience are thought to be crucial for the anticipation of positive affect and reward (Kring & Caponigro, ). Schizophrenia spectrum disorders and major depression are both associated with difficulties mentally simulating possible future events (Hallford, Austin, Takano, & Raes, ), and retrieving content in memory from which to construct these events (Berna et al ., ; Liu, Li, Xiao, Yang, & Jiang, ). This less vivid and specific mental simulation has been linked with affective variables, such as apathy (Raffard, Esposito, Boulenger, & Van der Linden, ), and subsequent motivation to engage in the imagined event or behaviour (Da Silva et al ., ).…”

Objectives. Deficits in anticipating pleasure may be an important dimension of anhedonia and functioning in psychiatric disorders, particularly schizophrenia and depression; however, inconsistent findings have limited the conclusions that can be drawn. We conducted the first systemic review and meta-analysis of the extant literature for research comparing psychiatric groups to healthy control groups on anticipatory pleasure.Methods. Academic Search Complete, Science Direct, and CINAHL databases were systematically searched up to 9 June 2018 for relevant peer-reviewed articles, book chapters, and dissertations. Reference lists were also hand searched. A total of 36 studies were included in the review. Results.A moderate-sized deficit was observed in schizophrenia spectrum disorders (k = 32, 1,851 patients and 1,449 controls, g = À0.42 [95% CI = À0.53 to À0.31], p < .001), and a large deficit in major depression (k = 415 patients and 506 controls, g = À0.87 [95% CI = À1.23 to À0.51], p < .001), with this effect being significantly larger for depression (p < .05). Meta-regression showed that heterogeneity was partially explained in schizophrenia spectrum by longer duration of illness and lower cognitive functioning predicting larger deficits. In depression, some evidence was found that ruling out a history of psychiatric illness in controls may be related to larger effects. There was evidence for small study bias inflating estimates in schizophrenia spectrum disorders.Conclusions. Deficits in anticipatory pleasure are manifest in these disorders, and significantly more so in major depression. These findings indicate a possible therapeutic target to link cognitive, affective, and behavioural factors that precipitate and maintain disorder. Practitioner pointsAnticipatory pleasure is impaired in schizophrenia spectrum and major depression. A particular focus on enhancing anticipatory pleasure may improve motivation for rewarding behaviour and psychosocial functioning. The review contained only a small number of studies for major depression. Given the heterogeneity in effects, there are likely to be more moderators of anticipatory pleasure that require examination.

Delay Discounting as a Transdiagnostic Process in Psychiatric Disorders

IMPORTANCE Delay discounting is a behavioral economic index of impulsive preferences for smaller-immediate or larger-delayed rewards that is argued to be a transdiagnostic process across health conditions. Studies suggest some psychiatric disorders are associated with differences in discounting compared with controls, but null findings have also been reported. OBJECTIVE To conduct a meta-analysis of the published literature on delay discounting in people with psychiatric disorders. DATA SOURCES PubMed, MEDLINE, PsycInfo, Embase, and Web of Science databases were searched through December 10, 2018. The psychiatric keywords used were based on DSM-IV or DSM-5 diagnostic categories. Collected data were analyzed from December 10, 2018, through June 1, 2019. STUDY SELECTION Following a preregistered Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol, 2 independent raters reviewed titles, abstracts, and full-text articles. English-language articles comparing monetary delay discounting between participants with psychiatric disorders and controls were included. DATA EXTRACTION AND SYNTHESIS Hedges g effect sizes were computed and random-effects models were used for all analyses. Heterogeneity statistics, one-study-removed analyses, and publication bias indices were also examined. MAIN OUTCOMES AND MEASURES Categorical comparisons of delay discounting between a psychiatric group and a control group. RESULTS The sample included 57 effect sizes from 43 studies across 8 diagnostic categories. Significantly steeper discounting for individuals with a psychiatric disorder compared with controls was observed for major depressive disorder (Hedges g = 0.37; P = .002; k = 7), schizophrenia (Hedges g = 0.46; P = .004; k = 12), borderline personality disorder (Hedges g = 0.60; P < .001; k = 8), bipolar disorder (Hedges g = 0.68; P < .001; k = 4), bulimia nervosa (Hedges g = 0.41; P = .001; k = 4), and binge-eating disorder (Hedges g = 0.34; P = .001; k = 7). In contrast, anorexia nervosa exhibited statistically significantly shallower discounting (Hedges g =-0.30; P < .001; k = 10). Modest evidence of publication bias was indicated by a statistically significant Egger test for schizophrenia and at the aggregate level across studies. CONCLUSIONS AND RELEVANCE Results of this study appear to provide empirical support for delay discounting as a transdiagnostic process across most of the psychiatric disorders examined; the literature search also revealed limited studies in some disorders, notably posttraumatic stress disorder, which is a priority area for research.
