RESUMO

OBJECTIVE: Loneliness is common among young people and is associated with negative health outcomes. Because loneliness is associated with a bias for interpreting social situations as threatening, cognitive bias modification for interpretation (CBM-I) training is a potential early intervention tool. We developed and delivered a single session of mental imagery enhanced digital CBM-I training, assessing feasibility, acceptability, and magnitude of change in interpretational style and loneliness. METHOD: CBM-I training materials were developed using a co-creation approach with 18-25-year-olds with experience of loneliness. Another group of 18-25-year-olds with high loneliness received either online CBM-I (n = 29) or control (n = 27) training. RESULTS: CBM-I training uptake and retention rates were 88% and 92%, respectively. Participants found the training acceptable. The CBM-I group showed a reduction in social threat interpretations (d = 0.77), an increase in social benign interpretations (d = 0.84), and a decrease in loneliness (d = 0.56). The control group showed a small reduction in social threat interpretations (d = 0.21), no change in social benign interpretations (d = 0.04), and an increase in loneliness (d = 0.41). CONCLUSIONS: Interpretation biases relevant to youth loneliness may be modifiable, and CBM-I training could reduce feelings of loneliness. This informs psychological models of loneliness, and the development of CBM-I interventions targeting loneliness in young people.

RESUMO

BACKGROUND: Negative emotions such as anxiety and depression may have a bearing on patients' psychological resilience and quality of life (QoL) following surgery. Cognitive bias modification (CBM) for attention and interpretation has been confirmed to alleviate anxiety and depression. However, the psychological effects of CBM attention and interpretation on Chinese patients with pituitary adenoma have hardly received research attention. METHODS: This prospective interventional study enrolled 100 patients undergoing surgical treatment for pituitary adenoma. Participants were divided into an experimental group and a control group, with 50 cases in each group. Baseline characteristics of included patients were collected. Patients in the control group were given routine training, and those in experimental group received routine training plus CBM attention and interpretation training. The Connor-Davidson Resilience Scale (CD-RISC) was used to assess patients' psychological resilience. The patients' levels of anxiety and depression were assessed using the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS). QoL was assessed based on the European Organization for Research and Treatment of Cancer QoL Questionnaire (EORTC QLQ-C30). RESULTS: No statistical difference was found between the 2 groups in CD-RISC, SAS, SDS, or QoL score at baseline (P>0.05). After CBM training, psychological resilience and QoL in the experimental group improved, and the levels of anxiety and depression decreased (P<0.05). Furthermore, the experimental group showed statistically superior psychological resilience and QoL than the control group. The levels of anxiety and depression in the experimental group were statistically lower than those in the control group (P<0.05). CONCLUSIONS: CBM for attention and interpretation effectively improves the psychological resilience of patients and reduces the symptoms of anxiety and depression, thus improving patients' postoperative QoL.

RESUMO

BACKGROUND: Cognitive bias modification (CBM) is a novel, but controversial intervention with considerable divergence amongst conclusions in individual studies and reviews. This systematic review synthesizes meta-analyses of CBM to determine whether CBM is effective, and what parameters most reliably evoke the process of CBM. METHODS: A systematic literature search resulted in twelve meta-analyses in total, from which the published effect sizes were extracted. RESULTS: Attention bias modification (ABM) shifted targeted biases in adults (ES = 0.24-1.16), was effective as a buffer to stressor vulnerability (ES = 0.33-0.77) and in symptom control (ES = 0.16-0.41). Cognitive bias modification for interpretation (CBM-I) modified targeted biases (ES = 0.52-0.81) but did not reliably reduce stressor vulnerability (ES = 0.01-0.24, p > .05). CBM consistently reduced anxiety symptoms, but effects on depressive symptomatology were less compelling. The long-term efficacy of CBM was only supported in addiction studies. LIMITATIONS: The review included a single CBM-I only meta-analysis, and two meta-analyses with pooled reporting on ABM and CBM-I outcomes. CONCLUSIONS: Overall, this synthesis shows CBM is effective in the short-term for anxiety in adults, and highlights some conditions under which CBM is most efficacious. Rather than debating the efficacy of CBM, future research should focus on developing procedures that more reliably induce bias modification and determining the most efficacious clinical applications.

RESUMO

BACKGROUND: Lack of trust in parental support is a transdiagnostic risk factor for the development of psychological problems throughout the lifespan. Research suggests that children's cognitive attachment representations and related information processing biases could be an important target for interventions aiming to build trust in the parent-child relationship. A paradigm that can alter these biases and increase trust is that of Cognitive Bias Modification (CBM), during which a target processing bias is systematically trained. Trust-related CBM training effects could possibly be enhanced by oxytocin, a neuropeptide that has been proposed to play an important role in social information processing and social relationships. The present article describes the study protocol for a double-blind randomized controlled trial (RCT) aimed at testing the individual and combined effects of CBM training and oxytocin administration on trust in maternal support. METHODS/DESIGN: One hundred children (aged 8-12 years) are randomly assigned to one of four intervention conditions. Participants inhale a nasal spray that either contains oxytocin (OT) or a placebo. Additionally, they receive either a CBM training aimed at positively modifying trust-related information processing bias or a neutral placebo training aimed to have no trust-related effects. Main and interaction effects of the interventions are assessed on three levels of trust-related outcome measures: trust-related interpretation bias; self-reported trust; and mother-child interactional behavior. Importantly, side-effects of a single administration of OT in middle childhood are monitored closely to provide further information on the safety of OT administration in this age group. DISCUSSION: The present RCT is the first study to combine CBM training with oxytocin to test for individual and combined effects on trust in mother. If effective, CBM training and oxytocin could be easily applicable and nonintrusive additions to interventions that target trust in the context of the parent-child relationship.

RESUMO

Cognitive models of Posttraumatic Stress Disorder (PTSD) postulate that cognitive biases in attention, interpretation, and memory represent key factors involved in the onset and maintenance of PTSD. Developments in experimental research demonstrate that it may be possible to manipulate such biases by means of Cognitive Bias Modification (CBM). In the present paper, we summarize studies assessing cognitive biases in posttraumatic stress to serve as a theoretical and methodological background. However, our main aim was to provide an overview of the scientific literature on CBM in (analogue) posttraumatic stress. Results of our systematic literature review showed that most CBM studies targeted attentional and interpretation biases (attention: five studies; interpretation: three studies), and one study modified memory biases. Overall, results showed that CBM can indeed modify cognitive biases and affect (analog) trauma symptoms in a training congruent manner. Interpretation bias procedures seemed effective in analog samples, and memory bias training proved preliminary success in a clinical PTSD sample. Studies of attention bias modification provided more mixed results. This heterogeneous picture may be explained by differences in the type of population or variations in the CBM procedure. Therefore, we sketched a detailed research agenda targeting the challenges for CBM in posttraumatic stress.

RESUMO

BACKGROUND: Young adults often experiment with heavy use of alcohol, which poses severe health risks and increases the chance of developing addiction problems. In clinical patients, cognitive retraining of automatic appetitive processes, such as selective attention toward alcohol (known as "cognitive bias modification of attention," or CBM-A), has been shown to be a promising add-on to treatment, helping to prevent relapse. OBJECTIVE: To prevent escalation of regular use into problematic use in youth, motivation appears to play a pivotal role. As CBM-A is often viewed as long and boring, this paper presents this training with the addition of serious game elements as a novel approach aimed at enhancing motivation to train. METHODS: A total of 96 heavy drinking undergraduate students carried out a regular CBM-A training, a gamified version (called "Shots"), or a placebo training version over 4 training sessions. Measures of motivation to change their behavior, motivation to train, drinking behavior, and attentional bias for alcohol were included before and after training. RESULTS: Alcohol attentional bias was reduced after training only in the regular training condition. Self-reported drinking behavior was not affected, but motivation to train decreased in all conditions, suggesting that the motivational features of the Shots game were not enough to fully counteract the tiresome nature of the training. Moreover, some of the motivational aspects decreased slightly more in the game condition, which may indicate potential detrimental effects of disappointing gamification. CONCLUSIONS: Gamification is not without its risks. When the motivational value of a training task with serious game elements is less than expected by the adolescent, effects detrimental to their motivation may occur. We therefore advise caution when using gamification, as well as underscore the importance of careful scientific evaluation.

RESUMO

Los sesgos cognitivos juegan un papel importante como factores de vulnerabilidad en los trastornos emocionales. Recientemente se han empezado a desarrollar intervenciones para la Modificación de Sesgos Cognitivos (MSC), con el objetivo final de mejorar los síntomas clínicos. Aunque estos procedimientos innovadores se han utilizado más en los problemas de ansiedad, existe una investigación creciente sobre su uso en la depresión. En este trabajo efectuamos una revisión del marco teórico, los procedimientos utilizados y los principales resultados de la MSC en la depresión, en especial en la corrección de sesgos atencionales y de interpretación. Finalmente se analizan las limitaciones conceptuales y metodológicas de estas nuevas intervenciones y se discuten sus implicaciones clínicas, teóricas y aplicadas.


Cognitive biases play an important role as vulnerability factors in emotional disorders. Interventions for Cognitive Bias Modification (CBM) have recently begun to be developed with the ultimate goal of improving clinical symptoms. Although these innovative procedures have been applied mainly in anxiety problems, there is increasing research on the application in depression. This work reviews the theoretical framework, the procedures used, and the main results of CBM in depression, especially in the modification of attention and interpretative bias. Finally the conceptual and methodological limitations of these promising interventions procedures are analyzed as well as the clinical, theoretical and applied implications.

RESUMO

BACKGROUND: Accruing evidence suggests that positive imagery-based cognitive bias modification (CBM) could have potential as a standalone targeted intervention for depressive symptoms or as an adjunct to existing treatments. We sought to establish the benefit of this form of CBM when delivered prior to Internet cognitive behavioral therapy (iCBT) for depression METHODS: A randomized controlled trial (RCT) of a 1-week Internet-delivered positive CBM vs. an active control condition for participants (N=75, 69% female, mean age=42) meeting diagnostic criteria for major depression; followed by a 10-week iCBT program for both groups. RESULTS: Modified intent-to-treat marginal and mixed effect models demonstrated no significant difference between conditions following the CBM intervention or the iCBT program. In both conditions there were significant reductions (Cohen׳s d .57-1.58, 95% CI=.12-2.07) in primary measures of depression and interpretation bias (PHQ9, BDI-II, AST-D). Large effect size reductions (Cohen׳s d .81-1.32, 95% CI=.31-1.79) were observed for secondary measures of distress, disability, anxiety and repetitive negative thinking (K10, WHODAS, STAI, RTQ). Per protocol analyses conducted in the sample of participants who completed all seven sessions of CBM indicated between-group superiority of the positive over control group on depression symptoms (PHQ9, BDI-II) and psychological distress (K10) following CBM (Hedges g .55-.88, 95% CI=-.03-1.46) and following iCBT (PHQ9, K10). The majority (>70%) no longer met diagnostic criteria for depression at 3-month follow-up. LIMITATIONS: The control condition contained many active components and therefore may have represented a smaller 'dose' of the positive condition. CONCLUSIONS: Results provide preliminary support for the successful integration of imagery-based CBM into an existing Internet-based treatment for depression.

RESUMO

Adolescence is a period of major risk for depression, which is associated with negative personal, social, and educational outcomes. Yet, in comparison to adult models of depression, very little is known about the specific psychosocial stressors that contribute to adolescent depression, and whether these can be targeted by interventions. In this review, we consider the role of peer rejection. First, we present a comprehensive review of studies using innovative experimental paradigms to understand the role of peer rejection in adolescent depression. We show how reciprocal relationships between peer rejection and depressive symptoms across adolescence powerfully shape and maintain maladaptive trajectories. Second, we consider how cognitive biases and their neurobiological substrates may explain why some adolescents are more vulnerable to the effects of, and perhaps exposure to, peer rejection compared to others. Finally, we draw attention to emerging cognitive and functional magnetic resonance imaging-based neurofeedback training, which by modifying aspects of information processing may promote more adaptive responses to peer rejection. A better understanding of the mechanisms underlying adolescent depression may not only alleviate symptoms during a period of substantial developmental challenges, but may also reduce the burden of the disorder across the lifespan.
