RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: Extending on previous findings that computerized Memory Specificity Training (c-MeST) improves memory specificity and depressive symptoms in Major Depressive Disorder (MDD) in adults, this study aimed to assess the effects of c-MeST in youth with MDD on memory specificity and depression in addition to other treatment. METHODS: Participants aged 15-25 (N = 359, 76 % female; M age = 19.2, SD = 3.1), receiving predominantly psychological therapy or counseling (85 %) and/or antidepressants (52 %) were randomized to usual care and c-MeST or usual care. Cognitive and clinical outcomes were assessed at baseline and at one, three, and six-month follow-ups. RESULTS: The usual care and c-MeST group reported higher memory specificity at one-month (d = 0.42, p = .022), but not at three or six months (d's < 0.15, p's > 0.05). The rate of MDE was numerically lower in the c-MeST group at each follow-up time-point, but group was not a statistically significant predictor at one month (64 % usual care and c-MeST vs. 68 % usual care, OR = 0.81, p = .606), three months (67 % usual care and c-MeST vs. 72 % usual care, OR = 0.64, p = .327) or six months (55 % usual care and c-MeST vs. 68 % usual care, OR = 0.56, p = .266). The usual care and c-MeST group did report lower depressive symptoms at one month (d = 0.42, p = .023) and six-months (d = 0.84, p = .001), but not three-months (d = 0.13, p > .05). CONCLUSIONS: c-MeST may reduce symptoms in youth with MDD when provided alongside other treatments. However, there are significant limitations to this inference, including high attrition in the study and a need for more data on the acceptability of the intervention.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Emotion regulation is postulated to play an important role in Trichotillomania (TTM). Whilst a growing number of studies have examined the relationship between emotion regulation difficulties and TTM symptoms, there have been no attempts to evaluate the overall strength of this association or the quality of the evidence base. METHOD: This systematic review and meta-analysis aimed to synthesise findings from studies that have examined the relationship between emotion regulation difficulties and TTM symptoms, to inform future TTM treatment targets. We identified 17 studies that met inclusion criteria. From these studies, 32 correlation coefficients were extracted for meta-analysis. The Joanna Briggs Institute Checklist for Analytical Cross Sectional Studies was used to assess risk of bias amongst the included studies. RESULTS: There was a moderately sized association between TTM symptoms and ER difficulties, (r adjusted = 0.32, 95 % CI [0.28, 0.37], t = 15.58 (df = 11.86), p < 0.0001) that was moderated by sample size (F(df1 = 1, df2 = 30) = 4.597, b = -0.0001, SE = 0.0001, 95 % CI [-0.0002; 0.0000], p = 0.040) and differences between types of emotion regulation measures (Q(df = 1) = 4.06, p = 0.044). LIMITATIONS: The data analysed was correlational, therefore causality was unable to be determined. Comorbidities were not able to be examined as a moderator. CONCLUSION: This study provided a preliminary integration of the evidence and demonstrated that individuals with higher levels of TTM severity appear to exhibit decreased overall emotion regulation abilities and strategies.

RESUMO

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.

RESUMO

The precise nature of the relationship between mindfulness, psychological flexibility (PF) and psychopathology in schizophrenia spectrum disorders (SSD) remains largely unclear and warrants further investigation. We recruited 43 persons with SSD and 43 controls. Our findings revealed that SSD showed lower mindfulness and PF than controls. Mindfulness was associated with higher PS, anticipatory pleasure, behavioral activation, and lower depressive and negative symptoms. PS was associated with lower depressive and negative symptoms and higher anticipatory pleasure and behavioral activation. The outcomes imply that targeting mindfulness and PF may prove beneficial in alleviating the amotivational psychopathology exhibited in SSD.

RESUMO

Autobiographical reasoning is a process by which an individual creates a coherent life account. The degree of coherence in autobiographical reasoning has been related to psychological health correlates such as depression and self-esteem in previous studies, but with inconsistent findings. Similarly, the basic psychological processes required to achieve coherence have been previously studied with regard to intelligence, but infrequently, and also with mixed findings. In the present study, we first developed and evaluated a German version of the Awareness of Narrative Identity Questionnaire (ANIQ) as an established measure of self-reported coherence. Second, we tested for cognitive dependencies on intelligence and memory indices. Third, we analysed its associations with psychological health correlates. We assessed a sample of 272 participants and thereof 189 participants again two-weeks later. Results supported the assumptions of the German ANIQ's psychometric qualities (factor structure, test-retest reliability, invariance) and validity (with regard to self-consciousness, self-concept clarity, and written accounts of personal turning points). We found coherence to be independent of intelligence and verbal memory, but partially dependent on figural memory. Coherence was related to depression, positivity, self-esteem, and self-esteem stability, but not to anxiety, substantiating its salutogenic effects.

RESUMO

Individuals build a narrative identity through the construction of an internalised, unfolding life story based on significant autobiographical memories. The current study validated a Dutch version of the Awareness of Narrative Identity Questionnaire (ANIQ-NL), which assesses how aware individuals are of having a narrative identity as well as their perception of the global coherence within their autobiographical memories, specifically, in terms of temporal ordering, causal connections and thematic integration. The questionnaire was administered to 541 adults (65.1% female, Mage = 34.09, SDage = 15.04, age range = 18-75). The results of a confirmatory factor analysis provided evidence for a four-factor structure, consisting of awareness and the three coherence subscales. The factor loadings of the items varied between .67 and .96. Moreover, the ANIQ-NL subscales showed good to excellent internal consistency, with Cronbach's alphas ranging from .86 to .96. Furthermore, higher levels of perceived autobiographical memory coherence were found to be significantly correlated to lower levels of depression, anxiety, and stress symptoms. The ANIQ-NL was determined to be a valid and reliable tool to measure narrative identity awareness and perceived narrative coherence. Future research could utilise the ANIQ-NL to further investigate the role of narrative identity in psychological well-being.

RESUMO

Sext dissemination (i.e., the online sharing of sexually explicit images) has the potential to result in legal, social, and psychological harms. Recent research has shown that this behavior can be consensual or non-consensual in nature; yet little is known about how motivations or attitudes may differ between these forms, or with gender. This study is based on a cross-sectional online survey investigating consensual and non-consensual sext dissemination and associated demographic, behavioral, attitudinal, and psychological factors. Participants were 2,126 cisgendered adults aged 18 to 30 years (M = 22.97, SD = 3.21, 55% women, 45% men), resident in Western, English-speaking nations, particularly Australia. Around 10% of respondents reported disseminating texts, and of these, only 19.8% indicated they had permission for this, with no differences across gender. When sexts were disseminated "to gossip," this was significantly more likely to be non-consensual. There were no significant differences between consensual and non-consensual dissemination in subjective attitudes or norms toward dissemination, nor levels of psychological distress. Women were more likely to non-consensually disseminate sexts that had been received as unwanted or unwelcome. Consensual dissemination was weakly associated with being sexually active and having given consent to having one's own images disseminated. We discuss implications for future research regarding consent, and relationship and sexuality education.

RESUMO

Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online computerised memory specificity training (c-MeST) data to examine whether directly retrieved OGM for negative cues prospectively predicts high levels of depression 1 month later. Participants who met the criteria of current major depressive disorders (N = 116; n = 58 in the c-MeST group and n = 58 in the control group) recalled autobiographical memories for positive and negative cues and judged each retrieval process (i.e. direct or generative). The results supported our prediction, and directly retrieved OGM for negative cues predicted high levels of depressive symptoms 1 month later even after controlling for the group effect, baseline depressive symptoms, executive functioning and rumination. Exploratory analysis showed that direct retrieval of specific memories prospectively predicted low levels of depression. These results support the theory that elevated accessibility of negatively valenced general memory representations is a vulnerability factor for depressive symptoms.

RESUMO

BACKGROUND AND OBJECTIVES: Overgeneral autobiographical memory (OGM) has been shown to occur in depressed and previously depressed populations regardless of the emotional valence of cues. However, recent research has pointed out that the retrieval process underlying OGM, generative retrieval (i.e., retrieval requiring effort or additional information) or direct retrieval (i.e., memory that comes to consciousness without effort or additional information), may differ depending on the emotional valence of cues. We examined the hypotheses that a remitted MDD (major depressive disorder), group compared with a control group, would show (a) more direct retrieval of categoric memories for negative cues, (b) more generative retrieval of categoric memories for positive cues, and (c) less direct retrieval of specific memories for positive cues. METHODS: A remitted clinical MDD group (n = 21) and control group (n = 21) completed the Autobiographical Memory Test with minimal instruction, and were required to subjectively judge generative retrieval and direct retrieval. RESULTS: As expected, results showed that the remitted MDD group reported more frequent direct retrieval of categoric memory for negative cues and more generative retrieval of categoric memory for positive cues than the control group. LIMITATIONS: Our paradigm for distinguishing between generative and direct retrieval relied on subjective judgements. CONCLUSIONS: This extends the findings from student sample in previous studies to a help-seeking population. Increased availability of negative categoric memories and the attenuation of positive specific recall represent vulnerabilities for MDD. We discuss how these findings provide further rationale for memory therapeutics for MDD and refinement of those techniques.

RESUMO

Child sexual exploitation (CSE) is a serious and persistent global issue affecting up to 5% of the child and youth population worldwide; yet there is no universally accepted definition. To develop a theoretically robust definition of CSE, this review systematically synthesized literature examining CSE definitions aiming to develop a conceptual model and typology. Electronic databases were searched to February 2021, yielding 384 nonduplicative records. Inclusion criteria were peer-reviewed and grey literature investigations of sexual exploitation, with a mean sample age of 18 years or younger, available in the English language. Literature review and data extraction followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Sixty-six studies met final inclusion criteria. Two independent reviewers extracted relevant data and used an epistemological approach to thematically analyse meaning and patterns across CSE definitions. Key findings demonstrate that CSE nomenclature is widely inconsistent, and despite growing awareness of this severe form of abuse, language continues to perpetuate stigma and criminalisation, utilising terms such as 'adolescent or child prostitute'. Our findings propose a scientifically and trauma-informed definition and conceptualisation of CSE, based on the following four-dimensional components: (1) A child/young person; (2) sexual acts; (3) abuse; and (4) exploitation (abuse + exchange). In this systematic review, a unified definition and conceptual model aims to advance knowledge and understanding of CSE, contributing to the progression of social norms which embrace nuances of trauma-informed practice and support for the identification and recovery of children, young people and families affected by sexual exploitation.

RESUMO

Several decades of research have established reduced autobiographical memory specificity, or overgeneral memory, as an important cognitive factor associated with the risk for and maintenance of a range of psychiatric diagnoses. In measuring this construct, experimenters code autobiographical memories for the presence or absence of a single temporal detail that indicates that the remembered event took place on a single, specific, day (Last Thursday when I rode bikes with my son), or multiple days (When I rode bikes with my son). Studies indicate that the specificity of memories and the amount of other episodic detail that they include (e.g., who, what, and where) are related and may rely on the same neural processes to elicit their retrieval. However, specificity and detailedness are nonetheless separable constructs: imperfectly correlated and differentially associated with current and future depressive symptoms and other associated intrapersonal (e.g., rumination) and interpersonal (e.g., social support) outcomes. The ways in which the details of our memories align with narrative themes (i.e., agency, communion, identity) and the coherence with which these details are presented, are also emerging as important factors associated with psychopathology. The temporal specificity of autobiographical memories may be important, but other memory constructs warrant further attention in research and theory, especially given the associations, and dependencies, between each of these constructs. Researchers in this area must consider carefully whether their research questions necessitate a focus on autobiographical memory specificity or whether a more inclusive analysis of other autobiographical memory features is necessary and more fruitful. This article is categorized under: Psychology > Memory.

RESUMO

Difficulty in accessing specific memories, referred to as reduced memory specificity or overgeneral memory (OGM), has been established as a marker of clinical depression. However, it is not clear if this deficit persists following the remission of depressive episodes. The current study involved a systematic review and meta-analysis of empirical studies with the aim of establishing whether remitted depression was associated with retrieving fewer specific and more overgeneral autobiographical memories. Seventeen studies were identified as eligible. The results indicated that people with remitted depression recalled fewer specific memories (k = 15; g = -0.314, 95% CI [-0.543; -0.085], z = -2.69, p = .007) and more categoric memories (k = 9; g = 0.254, 95% CI [0.007; 0.501], z = 2.02, p = .043) compared to people who had never been depressed. Given these deficits have elsewhere been shown to be prognostic of future depressive symptoms, these findings suggest that reduced memory specificity/overgeneral memory persists following remission and may be a risk factor for future episodes of depression in those that are in remission. The findings are discussed in terms of how this knowledge might influence clinical understanding of relapse prevention and maintenance of remission in those with a history of depression.

RESUMO

Suicide remains a leading cause of preventable death worldwide, despite advances in research and decreases in mental health stigma through government health campaigns. Machine learning (ML), a type of artificial intelligence (AI), is the use of algorithms to simulate and imitate human cognition. Given the lack of improvement in clinician-based suicide prediction over time, advancements in technology have allowed for novel approaches to predicting suicide risk. This systematic review and meta-analysis aimed to synthesize current research regarding data sources in ML prediction of suicide risk, incorporating and comparing outcomes between structured data (human interpretable such as psychometric instruments) and unstructured data (only machine interpretable such as electronic health records). Online databases and gray literature were searched for studies relating to ML and suicide risk prediction. There were 31 eligible studies. The outcome for all studies combined was AUC = 0.860, structured data showed AUC = 0.873, and unstructured data was calculated at AUC = 0.866. There was substantial heterogeneity between the studies, the sources of which were unable to be defined. The studies showed good accuracy levels in the prediction of suicide risk behavior overall. Structured data and unstructured data also showed similar outcome accuracy according to meta-analysis, despite different volumes and types of input data.
