Adolescents can be at heightened risk for anxiety and depression, with accumulating research reporting on associations between anxiety and depression and cognitive impairments, implicating working memory and attentional control deficits. Several studies now point to the promise of adaptive working memory training to increase attentional control in depressed and anxious participants and reduce anxiety and depression symptoms, but this has not been explored in a non-clinical adolescent population. The current study explored the effects of adaptive dual n-back working memory training on sub-clinical anxiety and depression symptomology in adolescents. Participants trained on either an online adaptive working memory task or non-adaptive control task for up to 20 days. Primary outcome measures were self-reported anxiety and depression symptomology, before and after intervention, and at 1-month follow-up. Self-reported depression (p = .003) and anxiety (p = .04) decreased after training in the adaptive n-back group relative to the non-adaptive control group in the intention-to-treat sample (n = 120). These effects were sustained at follow-up. Our findings constitute proof of principle evidence that working memory training may help reduce anxiety and depression vulnerability in a non-clinical adolescent population. We discuss the findings' implications for reducing risk of internalising disorders in youth and the need for replication. This article is protected by copyright. All rights reserved.

Recent work has suggested that anxiety restricts working memory capacity, which may underlie a wide range of cognitive symptoms in anxiety. However, previous literature on the anxiety-visual working m...
Low working memory (WM) capacity is associated with alcohol use disorders (AUDs). The importance of WM to adaptive functioning has led to a recent influx of studies attempting to improve individual WM...
Anxiety disorders are characterised by the perception of fear and threat in the presence of stimuli that are neutral or ambiguous. Attempts in previous research to explain the relationship between anx...
Alcohol use disorder (AUD) is associated with cognitive deficits such as impaired executive functions, which are hypothesized to contribute to the progression of the disease and worsen treatment outco...
The efficacy of cognitive training is controversial, and research progress in the field requires an understanding of factors that promote transfer of training gains and their relationship to changes i...

The purpose of this study is to investigate the effects of a computerized cognitive training program (an attention and memory exercise performed on a computer) on thinking and memory in in...
Cognitive impairment is a core symptom of schizophrenia and is in a large part responsible for the poor psychosocial outcome of the disorder. The use of non-invasive brain stimulation tech...
This study is an investigation of the effect of a computer-based working memory training program on memory and language processing in at-risk children (e.g., those with working memory weak...
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.
A self-administered version of the Primary Care Evaluation of Mental Disorders (PRIME-MD), a diagnostic tool containing modules on multiple mental health disorders including anxiety, alcohol, eating, and somatoform modules. The Patient Health Questionnaire (PHQ-9) is designed specifically for mood/depression scoring each of the 9 DSM-IV criteria based on the mood module from the original PRIME-MD. The Generalized Anxiety Disorder scale (GAD-7) scores 7 common anxiety symptoms.
Type of declarative memory, consisting of personal memory in contrast to general knowledge.
Decompression external to the body, most often the slow lessening of external pressure on the whole body (especially in caisson workers, deep sea divers, and persons who ascend to great heights) to prevent DECOMPRESSION SICKNESS. It includes also sudden accidental decompression, but not surgical (local) decompression or decompression applied through body openings.
Depression in POSTPARTUM WOMEN, usually within four weeks after giving birth (PARTURITION). The degree of depression ranges from mild transient depression to neurotic or psychotic depressive disorders. (From DSM-IV, p386)
