Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-1 (January 2011) . - p.24-32 Titre : Cognitive bias modification training in adolescents: effects on interpretation biases and mood Type de document : Texte imprimé et/ou numérique Auteurs : Claudia LOTHMANN, Auteur ; Emily A. HOLMES, Auteur ; Stella W. Y. CHAN, Auteur ; Jennifer Y.F. LAU, Auteur Année de publication : 2011 Article en page(s) : p.24-32 Langues : Anglais (eng) Mots-clés : Interpretation bias  adolescence  anxiety  mood  cognitive bias modification Index. décimale : PER Périodiques Résumé : Background:  Negative biases in the interpretation of ambiguous material have been linked to anxiety and mood problems. Accumulating data from adults show that positive and negative interpretation styles can be induced through cognitive bias modification (CBM) paradigms with accompanying changes in mood. Despite the therapeutic potential of positive training effects, training paradigms have not yet been explored in adolescents. Methods:  Eighty-two healthy adolescents (aged 13–17 years) were randomly allocated to either positive or negative CBM training. To assess training effects on interpretation bias, participants read ambiguous situations followed by test sentences with positive or negative interpretations of the situation. Participants rated the similarity of these sentences to the previously viewed ambiguous situations. Training effects on negative and positive affect were assessed using visual analogue scales before and after training. Results:  After training, adolescents in the negative condition drew more negative and fewer positive interpretations of new ambiguous situations than adolescents in the positive condition. Within the positive condition, adolescents endorsed more positive than negative interpretations. In terms of mood changes, positive training resulted in a significant decrease in negative affect across participants, while the negative condition led to a significant decrease in positive affect among male participants only. Conclusion:  This is the first study to demonstrate the plasticity of interpretation bias in adolescents. The immediate training effects on mood suggest that it may be possible to train a more positive interpretation style in youth, potentially helping to protect against anxiety and depressive symptoms.

Deactivation in anterior cingulate cortex during facial processing in young individuals with high familial risk and early development of depression: fMRI findings from the Scottish Bipolar Family Study / Stella W. Y. CHAN in Journal of Child Psychology and Psychiatry, 57-11 (November 2016)

Methods The Scottish Bipolar Family Study is a prospective longitudinal investigation examining young individuals (age 16–25) at familial risk of mood disorder. Participants underwent functional MRI using an implicit facial processing task employing angry and neutral faces. An explicit facial expression recognition task was completed outside the scanner. Clinical outcomes obtained 2 years after the scan were used to categorise participants into controls (n = 54), high-risk individuals who had developed MDD (HR MDD; n = 30) and high-risk individuals who remained well (HR Well, n = 43). Results All groups demonstrated activation patterns typically observed during facial processing, including activation of the amygdala, hippocampus, fusiform gyrus and middle frontal regions. Notably, the HR MDD group showed reduced activation of the anterior cingulate gyrus versus both the control and HR Well group for angry faces, and versus the HR Well group for neutral faces. Outside the scanner, the HR MDD group was less accurate in recognising fearful expressions than the HR Well group. Conclusions Here, we demonstrate functional abnormalities of the anterior cingulate cortex alongside facial emotional recognition deficits in high-risk individuals in the early stages of depression compared with both controls and at-risk individuals who remained well. These neural changes were associated with a current or future diagnosis of MDD and were not simply associated with increased familial risk.

Is cognitive bias modification training truly beneficial for adolescents? / Stella W. Y. CHAN in Journal of Child Psychology and Psychiatry, 56-11 (November 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-11 (November 2015) . - p.1239-1248 Titre : Is cognitive bias modification training truly beneficial for adolescents? Type de document : Texte imprimé et/ou numérique Auteurs : Stella W. Y. CHAN, Auteur ; Jennifer Y. F. LAU, Auteur ; Shirley A. REYNOLDS, Auteur Article en page(s) : p.1239-1248 Langues : Anglais (eng) Mots-clés : Cognitive Bias Modification  interpretation  adolescence  depression  anxiety  stress reactivity Index. décimale : PER Périodiques Résumé : 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.
