Cognitive bias modification of interpretations: A viable treatment for child and adolescent anxiety?

Anxiety disorders in children and adolescents: A summary and overview of the literature

Considerable work has advanced understanding of the nature, causes, management, and prevention of anxiety disorders in children and adolescents over the past 30 years. Prior to this time the primary focus was on school refusal and specific phobias. It is now recognised that children and adolescents experience the full gamut of anxiety disorders in very similar ways to adults and that anxiety disorders in the paediatric years can predict a lifelong mental-health struggle. Given the vast array of specific studies in this field, the current review summarises current knowledge about these high prevalence disorders, points to overarching limitations, and suggests potentially important future directions. Following a brief historical overview, the review summarises knowledge about demographic and epidemiological characteristics, distal and proximal risk factors, current treatment directions, and prevention. There is still a great deal to learn about the causes and treatments of child and adolescent anxiety disorders. By amalgamating our current knowledge, this review provides a window to the research directions that are likely to lead to future advances.

Developing an interpretation bias modification training task for alleviating loneliness in young people

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.

Study protocol for a randomized controlled trial investigating the effect of online interpretation bias intervention on stress reactivity in the children of parents with depression: the CoCo study

BACKGROUND

Current preventive interventions for the children of parents with depression demonstrate modest effects on depression incidence. This may be because existing interventions tend to comprise general psychotherapeutic tools, rather than targeting the specific mechanisms underlying familial transmission. Improved theoretical models of familial transmission could enhance the development of targeted interventions. Although existing models assume that cognitive and biological vulnerability factors influence one another, the precise mechanisms are unknown. This project is the first to experimentally test whether negative interpretation bias has an impact on cortisol response in children of parents with depression. This study protocol reports a randomised controlled trial of an interpretation bias intervention which aims to shift participants' interpretation bias in a more positive direction and thereby alter their stress response.

METHODS

Children aged 10-14 years who have i) one parent with a current or previous depression diagnosis, with at least one episode occurring during the child's lifetime and ii) do not have a current or previous psychiatric diagnosis themselves, will be assigned to one of two conditions: an interpretation bias intervention (n = 50) or a structurally similar placebo intervention (n = 50). The interpretation bias intervention consists of a short lab-based cognitive reappraisal of interpretations training, a four-week app-based Cognitive Bias Modification of Interpretations intervention and interpretation bias specific if-then plans. Interpretation bias will be assessed before and after the intervention using the Scrambled Sentences Task. The effect of the intervention on participants' stress response will be assessed by salivary cortisol collected at five different time points: from immediately before until 45 min after administering the Trier Social Stressor Test for Children. Stress reactivity will be measured via baseline to peak cortisol and stress recovery will be measured via the 45 min cortisol marker. We hypothesise that children who participate in the interpretation bias intervention will display a positive shift in interpretation bias and this, in turn, will alter their stress response. Children who receive the placebo intervention are expected to show a smaller positive shift in interpretation bias and stress reactivity.

DISCUSSION

The findings of the present study will contribute to models of familial depression transmission as well as informing preventive interventions. If training a more positive interpretation bias subsequently alters participants' stress response, then incorporating such tools may increase the efficacy of existing preventive interventions.

Early Life Maltreatment and Adolescent Interpretations of Ambiguous Social Situations: Investigating Interpersonal Cognitions and Emotional Symptoms

In the general population, negative interpretations of social situations have been associated with risk of developing emotional disorders such as anxiety and depression. Given that childhood maltreatment poses risk for later emotional disorders, this study examined whether interpersonal cognitive style differentiated maltreated adolescents from their non-maltreated peers and correlated with emotional symptoms across each group. Forty-seven maltreated and 28 non-maltreated adolescents were recruited from New South Wales, Australia to complete a battery of questionnaires that assessed interpersonal cognitions and levels of anxiety and depression. Comparable endorsement of threatening interpretations of social situations between maltreated adolescents and their non-maltreated peers across measures was found. Furthermore, an association between anxiety and depressive symptoms and interpretation bias was found within the non-maltreatment group but not the maltreated group. Unlike general population samples, negative cognitions do not associate with emotional symptoms in victims of early maltreatment. More research is needed to investigate the cognitive factors maintaining emotional symptoms in adolescent victims of maltreatment.

Can we challenge attention and interpretation threat biases in rescued child labourers with a history of physical abuse using a computerised cognitive training task? Data on feasibility, acceptability and target engagement

Child labourers are more likely to have experienced physical victimisation, which may increase risk for anxiety/depression, by shaping threat biases in information-processing. To target threat biases and vulnerability for anxiety/depression, we evaluated whether Cognitive Bias Modification (CBM) training could be feasibly and acceptably delivered to rescued youth labourers. Seventy-six physically abused rescued labourers aged 14-17 (40 from Nepal, 36 from India) in out-of-home care institutions received either multi-session computerised CBM or control training. Training targeted attention away from threat to positive cues and the endorsement of benign over threat interpretations. Feasibility and acceptability data were gathered along with pre and post intervention measures of attention and interpretation bias and emotional and behavioural symptoms. In terms of feasibility, uptake (proportion of those who completed the pre-intervention assessment from those who consented) and retention (proportion of those who completed the post-intervention assessment from those who completed the pre-intervention assessment) were above 75% in both countries. Average acceptability ratings were mostly 'moderate' on most indices for both countries, and none of the participants reported experiencing serious adverse events or reactions in response to or during the trial. Secondarily, CBM participants showed increased attention to positive and decreased attention to threatening stimuli, as well as increased endorsement of benign interpretation and decreased endorsement in negative interpretations of ambiguous social situations. Symptom changes were less clear. Delivering CBM to former child labourers in out-of-home care institutions has interventive potential.

Like parent, like child: Is parent interpretation bias associated with their child's interpretation bias and anxiety? A systematic review and meta-analysis

BACKGROUND

Anxiety disorders are the most prevalent psychiatric problem across the lifespan, with typical onset during the pediatric period. Prior literature has examined cognitive mechanisms associated with youth anxiety and identified interpretation bias, the threatening appraisal of ambiguity, as a ubiquitous correlate and likely mechanism. A small set of studies have examined interpretation bias and anxiety in parent-child dyads, although results about this potential relationship are conflicted. This systematic review and meta-analysis investigates the association between parent interpretation bias with child interpretation bias and child anxiety.

METHODS

Eight studies met the rigorous inclusion criteria, which required direct assessment of interpretation bias in both youth and parent.

RESULTS

Meta-analysis with a random effects model indicated a small and significant correlation between parent and child interpretation biases (r = 0.14, p < .01), as well as a small and significant correlation between parent interpretation bias and child anxiety (r =  = 0.20, p = .01).

LIMITATIONS

As only eight studies were included in this meta-analysis, reflecting the state of the extant literature, it is possible that, as data accumulate and this work continues in the future, results may or may not be replicated.

CONCLUSIONS

Despite variability in findings across the included empirical studies, the current meta-analysis suggests that a correlational relationship between parent interpretation bias and child bias/anxiety exists. This work has implications for conceptualizing parent interpretation bias as a possible explanatory mechanism underlying youth interpretation bias and anxiety.

Targeted self-regulation interventions in low-income children: Clinical trial results and implications for health behavior change

Self-regulation, known as the ability to harness cognitive, emotional, and motivational resources to achieve goals, is hypothesized to contribute to health behaviors across the lifespan. Enhancing self-regulation early in life may increase positive health outcomes. During pre-adolescence, children assume increased autonomy in health behaviors (e.g., eating; physical activity), many of which involve self-regulation. This article presents results from a clinical trial (NCT03060863) that used a factorial design to test behavioral interventions designed to enhance self-regulation, specifically targeting executive functioning, emotion regulation, future-oriented thinking, and approach biases. Participants were 118 children (9-12 years of age, M = 10.2 years) who had a history of living in poverty. They were randomized to receive up to four interventions that were delivered via home visits. Self-regulation was assayed using behavioral tasks, observations, interviews, and parent- and child-report surveys. Results were that self-regulation targets were reliably assessed and that interventions were delivered with high fidelity. Intervention effect sizes were very small to moderate (d range = .02-.65, median = .14), and most were not statistically significant. Intercorrelation analyses indicated that associations between measures within each target varied based on the self-regulation target evaluated. Results are discussed with regard to the role of self-regulation-focused interventions in child health promotion. Implications of findings are reviewed for informing next steps in behavioral self-regulation interventions among children from low-income backgrounds.

Emerging Domain-Based Treatments for Pediatric Anxiety Disorders

Domain-specific cognitive training treatments for pediatric anxiety disorders rely on accurate and reliable identification of specific underlying deficits and biases in neurocognitive functions. Once identified, such biases can serve as specific targets for therapeutic intervention. Clinical translations typically reflect mechanized training protocols designed to rectify the identified biases. Here, we review and synthesize research on key neurocognitive processes that emerge as potential targets for specialized cognitive training interventions in pediatric anxiety disorders in the domains of attention, interpretation, error monitoring, working memory, and fear learning. For each domain, we describe the current status of target establishment (i.e., an association between pediatric anxiety and a specific neurocognitive process), and then review extant translational efforts regarding these targets and the evidence supporting their clinical utility in youths. We then localize each of the domains within the path leading to efficacious, evidence-supported treatments for pediatric anxiety, providing a roadmap for future research. The review indicates that specific cognitive targets in pediatric anxiety have been established in all the reviewed domains except for fear learning, where a clear target is yet to be elucidated. In contrast, evidence for clinical efficacy emerged only in the threat-related attention domain, with some preliminary findings in the domains of interpretation and working memory. The path to clinical translation in the domain of error monitoring is yet unclear. Implications and potential avenues for future research and translation are discussed.

Are biased interpretations of ambiguous social and non-social situations a precursor, consequence or maintenance factor of youth loneliness?

Loneliness is common in youth, with suggestions that these negative emotions confer vulnerability for anxiety and depression. Here, we investigated for the first time whether, consistent with psychological models of loneliness, biased interpretations of social situations could prospectively predict loneliness in youth. 104 young people completed measures of loneliness and interpretations of ambiguous social and non-social (bodily or health-related) situations at three time-points with intervals of three months between each. As government-imposed social distancing measures (to control the COVID-19 outbreak) occurred between Times 2 and 3 (but not between Times 1 and 2), this enabled us to assess whether restricted social activity could provoke greater predictive power of biased interpretational styles on loneliness. Using cross-lagged panel models, we showed that after estimating paths representing within-time across-variable ("concurrent") paths and across-time within-variable ("stability") paths, there were no significant cross-lag 'causal' paths between earlier interpretational style and later loneliness. Between Time 2 and 3, we demonstrated a significant cross-lag 'consequential' path between earlier loneliness and later threatening interpretations of social situations, but this became non-significant after controlling for concurrent anxiety and depression. Biased interpretational style may reflect a concurrent maintenance factor of youth loneliness.

The relation between parental chronic pain, pain-related attention and interpretation biases in pain-free adolescents

BACKGROUND

Children of chronic pain patients run greater risk for developing chronic pain themselves. Exposure to chronic pain of the parent might install cognitive (e.g., pain catastrophizing, interpretation and attentional bias) and affective (e.g., pain anxiety) vulnerability which increase the risk for the development of chronic pain complaints in offspring. This study examines whether pain-free offspring of parents with chronic pain complaints make more health-threatening interpretations and display a stronger pain-related attentional bias compared to the offspring of pain-free parents. We furthermore examined differences between both groups on pain catastrophizing, pain anxiety and somatic symptoms and explored the relations between parental pain catastrophizing and aforementioned pain vulnerability measures in offspring.

METHODS

Offspring of parents with chronic pain complaints (n = 24) and pain-free parents (n = 27) completed measures of attentional bias (i.e., pictorial dot probe), interpretation bias (i.e., ambiguous word association task), pain catastrophizing, pain anxiety and somatic symptoms. Parents completed measures of pain catastrophizing and psychological distress.

RESULTS

No differences between offspring of parents with and without pain complaints were observed on pain catastrophizing, pain anxiety and somatic symptoms. Both groups of healthy adolescents predominantly showed benign, non-health-threatening interpretations. Children of pain-free parents showed an attention bias for pain stimuli, while offspring of parents with pain complaints showed no such bias.

CONCLUSIONS

Future research is needed to further elucidate the precise role of parental pain in the development of pain-related biases and the significance of these biases in the onset and/or maintenance of a chronic pain condition in children and adolescents.

SIGNIFICANCE

Parental chronic pain may install psychological vulnerability for developing chronic pain and associated complaints in offspring. This study did not show differences in pain-directed attentional and interpretation bias between offspring of parents with chronic pain complaints and offspring of pain-free parents. Further (longitudinal) research is needed to elucidate the precise role of parental pain factors in the development of pain-related vulnerability in offspring of chronic pain parents, thereby identifying important targets for the prevention and early intervention of chronic pain.

Translating CBM-I Into Real-World Settings: Augmenting a CBT-Based Psychiatric Hospital Program

Cognitive bias modification for interpretation (CBM-I) is an appealing augmentation to cognitive-behavioral therapy (CBT) because it targets cognitive bias efficiently via computerized training. Few studies have tested the combination of CBM-I and CBT, and none have translated lab-based CBM-I protocols to an acute psychiatric setting. The present study describes the development and implementation of CBM-I as an augmentation to a CBT-based partial hospital. We developed a transdiagnostic CBM-I based on the word-sentence association paradigm (WSAP), which reinforces individuals for endorsing benign interpretations and rejecting negative interpretations of ambiguous sentences. Over two iterations of development, we randomly assigned patients (N = 127; M age = 34.21; 58% female, 40% male, 2% nonbinary) to either CBM-I or a control group (Phase 1: neutral WSAP task; Phase 2: treatment as usual). CBM-I comprised daily sessions (10 minutes) completed during program hours, and number of sessions varied naturalistically according to patient length of stay. Primary outcomes included feasibility, acceptability, and target engagement (interpretation bias). CBM-I was feasible and acceptable to acute psychiatric patients, and successfully shifted interpretation for novel stimuli. Patient feedback suggested that participants viewed CBM-I as bolstering their primary CBT-based care. Exploratory analyses examining clinical benefit revealed a small between-group effect on anxiety severity (d = 0.378), but no group differences on depression outcomes (d = 0.008). Findings indicate that CBM-I is a feasible and acceptable augmentation to CBT-based partial hospital care. Future studies are warranted to determine who is most likely to benefit from this low-intensity approach.

Interpretation Bias Training in Depressed Adolescents: Near- and Far-Transfer Effects

Depressed adolescents are characterized by negative interpretation biases. Although investigators have used cognitive bias modification for interpretation (CBM-I) to experimentally manipulate interpretation biases in depressed adults, the near- and far-transfer effects are not well understood in adolescents diagnosed with Major Depressive Disorder (MDD). In this study, we extend previous research by investigating the near- and far-transfer effects of 6 sessions of Positive versus Neutral CBM-I on independent measures of interpretation bias (near-transfer effects) and on attention biases and clinical symptoms (far-transfer effects) in a sample of adolescents with MDD (n = 46). At post-training, adolescents who received Positive CBM-I interpreted ambiguous scenarios more positively than did participants who received Neutral CBM-I, providing evidence of training effectiveness. There was no evidence, however, of near- or far-transfer effects. These findings raise concerns about the malleability of interpretation biases in adolescent depression and suggest that further work is needed to establish the clinical utility of CBM-I for adolescents with MDD.

Research Review: Cognitive bias modification of interpretations in youth and its effect on anxiety: a meta-analysis

BACKGROUND

Emerging evidence suggests that cognitive bias modification of interpretations (CBM-I) is effective in altering interpretation biases and reducing anxiety in adults. Less is known about the impact of CBM-I in young people, but some recent findings, including a meta-analysis of combined cognitive bias modification of interpretation and attention techniques, have cast doubt on its clinical utility. Given the current debate, this meta-analysis sought to establish the independent effects of CBM-I on interpretations biases and anxiety in youth.

METHODS

Studies were identified through a systematic literature search of PsycINFO, Ovid MEDLINE, PsycARTICLES, Web of Science and EMBASE between January 1992 and March 2017. Eligible studies aimed to target interpretation biases; did not combine CBM-I with another intervention; included a control condition; randomly allocated participants to conditions; assessed interpretation bias and/or anxiety as an outcome; included individuals up to age 18; and did not present previously reported data. Reference lists of included articles were checked for further eligible studies, and authors were contacted for unpublished data.

RESULTS

We identified 26 studies meeting eligibility criteria that included in the meta-analysis. CBM-I had moderate effects on negative and positive interpretations (g = -0.70 and g = -0.52, respectively) and a small but significant effect on anxiety assessed after training (g = -0.17) and after a stressor (g = -0.34). No significant moderators were identified.

CONCLUSIONS

In contrast to previous meta-analytic findings, our results indicate that CBM-I has potential but weak anxiolytic effects in youth. Our findings suggest that it may be premature to disregard the potential value of CBM-I research and further research in this field is warranted.

A brief early intervention for adolescent depression that targets emotional mental images and memories: protocol for a feasibility randomised controlled trial (IMAGINE trial)

BACKGROUND

Adolescent depression is common and impairing. There is an urgent need to develop early interventions to prevent depression becoming entrenched. However, current psychological interventions are difficult to access and show limited evidence of effectiveness. Schools offer a promising setting to enhance access to interventions, including reducing common barriers such as time away from education. Distressing negative mental images and a deficit in positive future images, alongside overgeneral autobiographical memories, have been implicated in depression across the lifespan, and interventions targeting them in adults have shown promise. Here, we combine techniques targeting these cognitive processes into a novel, brief psychological intervention for adolescent depression. This feasibility randomised controlled trial will test the feasibility and acceptability of delivering this imagery-based cognitive behavioural intervention in schools.

METHODS/DESIGN

Fifty-six adolescents (aged 16-18) with high symptoms of depression will be recruited from schools. Participants will be randomly allocated to the imagery-based cognitive behavioural intervention (ICBI) or the control intervention, non-directive supportive therapy (NDST). Data on feasibility and acceptability will be recorded throughout, including data on recruitment, retention and adherence rates as well as adverse events. In addition, symptom assessment will take place pre-intervention, post-intervention and at 3-month follow-up. Primarily, the trial aims to establish whether it is feasible and acceptable to carry out this project in a school setting. Secondary objectives include collecting data on clinical measures, including depression and anxiety, and measures of the mechanisms proposed to be targeted by the intervention. The acceptability of using technology in assessment and treatment will also be evaluated.

DISCUSSION

Feasibility, acceptability and symptom data for this brief intervention will inform whether an efficacy randomised controlled trial is warranted and aid planning of this trial. If this intervention is shown in a subsequent definitive trial to be safe, clinically effective and cost-effective, it has potential to be rolled out as an intervention and so would significantly extend the range of therapies available for adolescent depression. This psychological intervention draws on cognitive mechanism research suggesting a powerful relationship between emotion and memory and uses imagery as a cognitive target in an attempt to improve interventions for adolescent depression.

A randomized controlled trial of multi-session online interpretation bias modification training: Short- and long-term effects on anxiety and depression in unselected adolescents

Introduction

Negatively biased interpretations play an important role in anxiety and depression, which are highly prevalent in adolescence, and changing such biases might thus reduce or prevent emotional disorders. We investigated the short- and long-term effects of an online interpretation bias modification training in unselected adolescents to explore its potential in preventing anxiety and depression.

Methods

Participants (N = 173) were randomly allocated to eight online sessions of interpretation or placebo training. Interpretation bias was assessed pre- and post-training. Primary outcomes of anxiety and depression, and secondary measures of emotional resilience were assessed pre- and post-training and at three, six, and twelve months follow-up.

Results

Compared to placebo, interpretation training marginally increased positive interpretations. Irrespective of training condition, symptoms of anxiety and depression showed a decline post-training and at follow-up, and indices of resilience showed an increase. Change in interpretation bias, baseline interpretation bias, stressful life events, or number of training sessions completed did not moderate the effects on anxiety or depression.

Conclusions

Results suggest that interpretation training as implemented in this study has no added value in reducing symptoms or enhancing resilience in unselected adolescents.

Targeting self-regulation to promote health behaviors in children

Poor self-regulation (i.e., inability to harness cognitive, emotional, motivational resources to achieve goals) is hypothesized to contribute to unhealthy behaviors across the lifespan. Enhancing early self-regulation may increase positive health outcomes. Obesity is a major public health concern with early-emerging precursors related to self-regulation; it is therefore a good model for understanding self-regulation and health behavior. Preadolescence is a transition when children increase autonomy in health behaviors (e.g., eating, exercise habits), many of which involve self-regulation. This paper presents the scientific rationale for examining self-regulation mechanisms that are hypothesized to relate to health behaviors, specifically obesogenic eating, that have not been examined in children. We describe novel intervention protocols designed to enhance self-regulation skills, specifically executive functioning, emotion regulation, future-oriented thinking, and approach bias. Interventions are delivered via home visits. Assays of self-regulation and obesogenic eating behaviors using behavioral tasks and self-reports are implemented and evaluated to determine feasibility and psychometrics and to test intervention effects. Participants are low-income 9-12 year-old children who have been phenotyped for self-regulation, stress, eating behavior and adiposity through early childhood. Study goals are to examine intervention effects on self-regulation and whether change in self-regulation improves obesogenic eating.

Examining the Mechanisms of Therapeutic Change in a Cognitive-Behavioral Intervention for Anxious Children: The Role of Interpretation Bias, Perceived Control, and Coping Strategies

This study examined the role of theoretically meaningful mediators of therapeutic change-interpretation bias, perceived control, and coping strategies-in a cognitive-behavioral intervention for anxious youth. This is one of the few studies that examined the change in potential mediator and outcome variables by means of a longitudinal design that included four assessment points: pretreatment, in-treatment, post-treatment, and at 4-months follow-up. Forty-seven 8- to 12-year-old children with a principal DSM-IV diagnosis of anxiety disorder participated in the study. On each assessment point, questionnaires assessing the mediator variables and a standardized anxiety scale were administered to the children. The results showed that perceived control and interpretation bias (but not coping strategies) accounted for a significant proportion in the variability of various types of anxiety symptoms, providing a preliminary support for the notion that these cognitive dimensions' act as mechanisms of therapeutic change in cognitive-behavioral therapy for anxious children.

Stuttering Thoughts: Negative Self-Referent Thinking Is Less Sensitive to Aversive Outcomes in People with Higher Levels of Depressive Symptoms

Learning theories of depression have proposed that depressive cognitions, such as negative thoughts with reference to oneself, can develop through a reinforcement learning mechanism. This negative self-reference is considered to be positively reinforced by rewarding experiences such as genuine support from others after negative self-disclosure, and negatively reinforced by avoidance of potential aversive situations. The learning account additionally predicts that negative self-reference would be maintained by an inability to adjust one’s behavior when negative self-reference no longer leads to such reward. To test this prediction, we designed an adapted version of the reversal-learning task. In this task, participants were reinforced to choose and engage in either negative or positive self-reference by probabilistic economic reward and punishment. Although participants were initially trained to choose negative self-reference, the stimulus-reward contingencies were reversed to prompt a shift toward positive self-reference (Study 1) and a further shift toward negative self-reference (Study 2). Model-based computational analyses showed that depressive symptoms were associated with a low learning rate of negative self-reference, indicating a high level of reward expectancy for negative self-reference even after the contingency reversal. Furthermore, the difficulty in updating outcome predictions of negative self-reference was significantly associated with the extent to which one possesses negative self-images. These results suggest that difficulty in adjusting action-outcome estimates for negative self-reference increases the chance to be faced with negative aspects of self, which may result in depressive symptoms.

Attention Bias to Emotional Faces Varies by IQ and Anxiety in Williams Syndrome

Individuals with Williams syndrome (WS) often experience significant anxiety. A promising approach to anxiety intervention has emerged from cognitive studies of attention bias to threat. To investigate the utility of this intervention in WS, this study examined attention bias to happy and angry faces in individuals with WS (N = 46). Results showed a significant difference in attention bias patterns as a function of IQ and anxiety. Individuals with higher IQ or higher anxiety showed a significant bias toward angry, but not happy faces, whereas individuals with lower IQ or lower anxiety showed the opposite pattern. These results suggest that attention bias interventions to modify a threat bias may be most effectively targeted to anxious individuals with WS with relatively high IQ.

Memory cueing during sleep modifies the interpretation of ambiguous scenes in adolescents and adults

The individual tendency to interpret ambiguous situations negatively is associated with mental disorders. Interpretation biases are already evident during adolescence and due to the greater plasticity of the developing brain it may be easier to change biases during this time. We investigated in healthy adolescents and adults whether stabilizing memories of positive or negative scenes modulates the later interpretation of similar scenes. In the evening, participants learnt associations between ambiguous pictures and words that disambiguate the valence of the pictures in a positive or negative direction. Half of the words were acoustically presented (i.e. cued) during post-learning sleep which is known to benefit memory consolidation by inducing reactivation of learned information. Cued compared to un-cued stimuli were remembered better the next morning. Importantly, cueing positively disambiguated pictures resulted in more positive interpretations whereas cueing negatively disambiguated pictures led to less positive interpretations of new ambiguous pictures with similar contents the next morning. These effects were not modulated by participants' age indicating that memory cueing was as efficient in adolescents as in adults. Our findings suggest that memory cueing during sleep can modify interpretation biases by benefitting memory stabilization and generalization. Implications for clinical settings are discussed.

Is cognitive bias modification training truly beneficial for adolescents?

BACKGROUND

Cognitive Bias Modification (CBM) has been shown to change interpretation biases commonly associated with anxiety and depression and may help ameliorate symptoms of these disorders. However, its evidence base for adolescents is scarce. Previous results have been hard to interpret because of methodological issues. In particular, many studies have used negative bias training as the control condition. This would tend to inflate any apparent benefits of CBM compared to a neutral control. Most studies also only examined the effects of a single training session and lacked follow-up assessment or ecologically valid outcome measures.

METHOD

Seventy-four adolescents, aged 16-18 years, were randomised to two sessions of CBM training or neutral control. Interpretation bias and mood were assessed three times: at baseline, immediately post-training and 1 week post-training. A controlled experimental stressor was also used, and responses to everyday stressors were recorded for 1 week after training to assess responses to psychological challenges. Feedback for the training programme was collected.

RESULTS

The CBM group reported a greater reduction in negative affect than control participants. However, other hypothesised advantages of CBM were not demonstrated. Regardless of training group, participants reported increased positive interpretations, decreased negative interpretations, reduced depressive symptoms and no change in trait anxiety. The two groups did not differ in their stress reactivity. After controlling for group differences in training performance, all the mood effects disappeared.

CONCLUSIONS

When tested under stringent experimental conditions the effects of CBM in healthy adolescents appear to be minimal. Future studies should concentrate on participants with elevated cognitive biases and/or mood symptoms who may be more sensitive to CBM.

Practitioner Review: Cognitive bias modification for mental health problems in children and adolescents: a meta-analysis

BACKGROUND

Despite accumulating research and bold claims about the efficacy of cognitive bias modification (CBM) for young populations, no meta-analysis has attempted to synthesize the research literature so far. We examined whether there was empirical evidence for the clinical efficacy of CBM interventions in youths, while also considering the methodological quality of this evidence.

METHODS

Studies were identified through systematic searches in bibliographical databases (PubMed, PsychInfo, Cochrane Library and EMBASE to June 2014). We included randomized controlled trials of CBM interventions, and considered both clinical outcomes and targeted biases. We examined the quality of the trials, as well as potential publication bias and possible moderators.

RESULTS

We identified 23 trials that reported on four types of outcomes: mental health, anxiety, depression and bias. Effect sizes were small and nonsignificant for all symptom outcomes considered. We found a moderate significant effect size for bias outcomes (Hedges' g of 0.53), with significant heterogeneity. There were no differences between types of CBM interventions, or between one versus multiple-session applications. A small but significant effect size for mental health problems arose when the intervention was delivered in schools. The quality of almost all of the included studies was suboptimal and the vast majority did not include information needed for allowing quality assessment.

CONCLUSIONS

We conducted the first meta-analysis of CBM interventions for children and adolescents and found no effects for mental health outcomes, but we did find moderate and significant effects on the targeted biases. Our results cast serious doubts on CBM interventions having any clinical utility for nonadult populations. Demand characteristics might play an important part in CBM research.

Commentary: A glass half full or half empty? Cognitive bias modification for mental health problems in children and adolescents--reflections on the meta-analysis by Cristea et al. (2015)

The last decade has cognitive bias modification (CBM) training paradigms, emerging first as an experimental test of the causal role of information-processing biases on mood and anxiety symptoms, and then, as the clinical implications of these findings were realised, as a potential clinical 'vaccine' that could be used to modify biases and reduce symptoms. CBM is an umbrella term for methods designed to modify cognitive factors that maintain psychiatric conditions such as anxiety and depression through simple repetitive learning. Two biases that have most often been targeted by these training programs are the tendency to orient attention towards threat and distortions in the interpretation of ambiguous situations. This commentary reflects on an accompanying meta-analysis by Crsitea et al., which pooled effect sizes from over 20 statistical comparisons between a CBM group and a control group on post-training measures of mental health (mostly anxiety and depression). Cristea et al. reported that any CBM training-associated difference on measures of anxiety and depression were weak and non-significant (although training effects were generally evident on measures of cognitive biases). Heterogeneity across studies was high, but with exception to the setting in which CBM was delivered (home, school, laboratory or mental health facility), there was no persuasive evidence for significant moderation of training effects by other key variables. In their conclusions the authors suggested that CBM had little clinical utility and that it was unclear whether positive results in any individual study arose from experimenter or participant bias. So if the glass is half empty, what should the next stage of CBM research usefully focus on?

Mental health problems in adolescence and the interpretation of unambiguous threat

Aberrant threat perception has been linked to paranoia, anxiety and other mental health problems, and is widely considered to be a core, transdiagnostic feature of psychopathology. However, to date there has been only limited investigation of whether mental health problems are associated with a biased interpretation of stimuli that have explicit (as opposed to ambiguous) connotations of threat. In the present study, 41 adolescents diagnosed with a mental illness and 45 demographically matched controls were asked to provide danger ratings of stimuli normatively rated as being either low or high in potential threat. All participants were also asked to complete background measures of cognitive function, mental health and wellbeing. The results indicated that the two groups did not differ in their capacity to discriminate between low and high threat stimuli, nor did they differ in the absolute level of threat that they attributed to these stimuli. However, for the control group, the overall level of threat perceived in facial stimuli was correlated with two important indices of mental health (depression and anxiety). No associations emerged in the clinical group. These data are discussed in relation to their potential implications for the role of aberrant threat perception in transdiagnostic models of mental health.

Social anxiety disorder in adolescence: How developmental cognitive neuroscience findings may shape understanding and interventions for psychopathology

Social anxiety disorder represents a debilitating condition that has large adverse effects on the quality of social connections, educational achievement and wellbeing. Age-of-onset data suggests that early adolescence is a developmentally sensitive juncture for the onset of social anxiety. In this review, we highlight the potential of using a developmental cognitive neuroscience approach to understand (i) why there are normative increases in social worries in adolescence and (ii) how adolescence-associated changes may 'bring out' neuro-cognitive risk factors for social anxiety in a subset of individuals during this developmental period. We also speculate on how changes that occur in learning and plasticity may allow for optimal acquisition of more adaptive neurocognitive strategies through external interventions. Hence, for the minority of individuals who require external interventions to target their social fears, this enhanced flexibility could result in more powerful and longer-lasting therapeutic effects. We will review two novel interventions that target information-processing biases and their neural substrates via cognitive training and visual feedback of neural activity measured through functional magnetic resonance imaging.

Positive Imagery-Based Cognitive Bias Modification as a Web-Based Treatment Tool for Depressed Adults: A Randomized Controlled Trial

Depression is a global health problem requiring treatment innovation. Targeting neglected cognitive aspects may provide a useful route. We tested a cognitive-training paradigm using positive mental imagery (imagery cognitive bias modification, imagery CBM), developed via experimental psychopathology studies, in a randomized controlled trial. Training was delivered via the Internet to 150 individuals with current major depression. Unexpectedly, there was no significant advantage for imagery CBM compared with a closely matched control for depression symptoms as a whole in the full sample. In exploratory analyses, compared with the control, imagery CBM significantly improved anhedonia over the intervention and improved depression symptoms as a whole for those participants with fewer than five episodes of depression and those who engaged to a threshold level of imagery. Results suggest avenues for improving imagery CBM to inform low-intensity treatment tools for depression. Anhedonia may be a useful treatment target for future work.

Single-Session Cognitive Bias Modification of Interpretations Training in High-Anxious Adolescents

Anxiety disorders in youths are globally prevalent and carry impairing, long-lasting effects. Interpreting ambiguous cues negatively may be causally related to adolescent anxiety. Extending cognitive bias modification of interpretations (CBM-I) training, which counters anxiety by encouraging positive interpretations, to anxious adolescents could inform the design of new interventions. The study investigates whether single-session CBM-I training (a) altered interpretation biases and negative mood in adolescents selected for high anxiety and (b) whether these training-associated changes were larger than those reported in low-anxious adolescents. Seventy-seven Chinese adolescents received either positive or control training. Positive training encouraged endorsement of positive interpretations of ambiguous scenarios while on control training trials, half of the scenarios were resolved positively and half negatively. A single session of CBM-I altered interpretation biases across all individuals, F(1, 52) = 10.63, p < .01, η2 = .17. However, no training effects on mood measures emerged (all ps > .05). Training effects were not consistently moderated by baseline trait anxiety. Multisession CBM-I may be needed for mood changes to occur.

Changes in the adolescent brain and the pathophysiology of psychotic disorders

Adolescence is a time of extensive neuroanatomical, functional, and chemical reorganisation of the brain which parallels substantial maturational changes in cognition and affect regulation. This period is characterised by stabilisation of synapses to diminish redundancy and increase efficiency of neural function, fine-tuning of excitatory and inhibitory neurotransmitter systems, beginning of integration between late maturing and early maturing brain structures, and development of effective connections. In effect, these so-called moving parts create a state of dynamic change that might underlie adolescent behaviours. Imbalances or changes in timing of these developmental processes clearly increase the risk for psychiatric disorders. Genetic, environmental, and epigenetic factors that shape brain development and hormonal changes that affect stress reactivity could be reasons why some, but not all, adolescents are at a heightened risk of developing a psychopathological disorder. In this Series paper, we assess the neurobiology of the changing adolescent brain, implications of this knowledge, and future research in major psychiatric disorders, particularly for psychotic disorders.

Interpretation bias modification for youth and their parents: a novel treatment for early adolescent social anxiety

Social anxiety is the most prevalent anxiety disorder of late adolescence, yet current treatments reach only a minority of youth with the disorder. Effective and easy-to-disseminate treatments are needed. This study pilot tested the efficacy of a novel, online cognitive bias modification for interpretation (CBM-I) intervention for socially anxious youth and their parents. The CBM-I intervention targeted cognitive biases associated with early adolescents' maladaptive beliefs regarding social situations, and with parents' intrusive behavior, both of which have been theoretically linked with the maintenance of social anxiety in youth. To investigate the efficacy of intervening with parents and/or children, clinically diagnosed early adolescents (ages 10-15; N=18) and their mothers were randomly assigned to one of three conditions: the first targeted early adolescents' cognitive biases related to social anxiety (Child-only condition); the second targeted parents' biases associated with intrusive behavior (Parent-only condition); and the third targeted both youth and parents' biases in tandem (Combo condition). The use of a multiple baseline design allowed for the efficient assessment of causal links between the intervention and reduction in social anxiety symptoms in youth. Results provided converging evidence indicating modest support for the efficacy of CBM-I, with no reliable differences across conditions. Taken together, results suggest that online CBM-I with anxious youth and/or their parents holds promise as an effective and easily administered component of treatment for child social anxiety that deserves further evaluation in a larger trial.

Interpersonal cognitive biases as genetic markers for pediatric depressive symptoms: twin data from the emotions, cognitions, heredity and outcome (ECHO) study

Childhood depressive symptoms may arise from genetic and environmental risks, which act to bias the ways in which children process emotional information. Previous studies show that several "cognitive biases" are heritable and share genetic and environmental risks with depressive symptoms. Past research suggests that many cognitive biases only reflect genetic risks for depressive symptoms from adolescence. The present study sought to identify (a) when interpersonal cognitions mature as risk factors for depressive symptoms by examining whether these factors are stable and predict symptoms across time in childhood, and (b) the extent to which interpersonal cognitions reflect inherited/environmental risks on children's depressive symptoms. Results showed that there was some stability for interpersonal cognitive biases from age 8 to 10 years (rs = .32-.43). Only the absence of positive self/other perceptions, and negative peer and mother expectations at age 8 predicted depressive symptoms at age 10 (after controlling for depressive symptoms at age 8). The absence of positive self/other perceptions shared genetic influences with depressive symptoms within and across time. Across middle to late childhood, interpersonal cognitions begin to operate as vulnerability-trait factors for depressive symptoms, gradually reflecting distal genetic risks on symptoms.

Trait Emotional Intelligence, Anxiety Sensitivity, and Experiential Avoidance in Stress Reactivity and Their Improvement Through Psychological Methods

Stress pervades daily society, often with deleterious consequences for those prone to react intensely to it. Intervention techniques to attenuate stress reactivity are thus paramount. With that goal in mind, researchers have sought to identify and alter malleable psychological dispositional variables that influence stress reactivity. Trait emotional intelligence (TEI), anxiety sensitivity (AS), and experiential avoidance (EA) are increasingly receiving attention in these research efforts. The self-reported emotional component of stress reactivity has been emphasized in investigations and is our focus. Specifically, this paper overviews the role of TEI, AS, and EA in self-reported stress responses. We also discuss empirically supported psychological methods to adjust suboptimal levels of these variables in normal populations. Both psycho-educational (information, skills) and mindfulness-based interventions (specific mindfulness therapies or components) are covered. Findings include that (1) TEI, AS, and EA are each correlated with the emotional component of stress reactivity to both naturalistic and lab-based stressors; (2) preliminary support currently exists for psycho-educational intervention of TEI and AS but is lacking for EA; (3) adequate evidence supports mindfulness-based interventions to target EA, with very limited but encouraging findings suggesting mindfulness methods improve TEI and AS; and (4) although more research is needed, stress management approaches based on mindfulness may well target all three of these psychological variables and thus appear particularly promising. Encouragingly, some methods to modify dispositional variables (e.g., a mindfulness-based format of guided self-help) are easily disseminated and potentially applicable to the general public.
