Summary

The purpose of this study is to investigate the effects of neurofeedback training on measures of cognitive control and alcohol motivation among young adults who drink alcohol on a regular basis. Neurofeedback is a cognitive training technique that uses portable electroencephalography (EEG) technology to adjust brain activity through immediate sensory feedback. This study is using a type of EEG device called a MuseTM headset that monitors ongoing brain activity and synchronizes this information with a mindfulness training app on a mobile device. This study is a pilot study to examine the feasibility and effects of neurofeedback training in a sample of young adults. Future studies may use similar protocols with people who have substance use disorders or other mental health disorders.

Detailed description

The NFB studies conducted to date have utilized a wide range of methodologies and NFB training protocols. The outcome measures of NFB efficacy have also varied widely. As mentioned above, the studies also used expensive, non-portable equipment which may limit the application of NFB in treatment settings. This study seeks to address these limitations by using a commercially-available neurotechnology, the Muse™ headband by InteraXon (Toronto, ON, Canada) and using their standard NFB protocol built into the device application. This will maximize the standardization and portability of the NFB as essentially an "out of the box" intervention. The outcome measures will also capture multiple relevant domains, including clinical outcomes (e.g., drinking motivation) and neurocognitive performance (e.g., cognitive control / response inhibition). The purpose of this study is to investigate the effects of NFB training on measures of cognitive control and alcohol motivation among young adults who engage in heavy episodic drinking (defined as exceeding 4+/5+ drinks per occasion for men/women). The study will examine whether NFB reduces motivation/attention and craving for alcohol and attentional bias to alcohol-related cues. The primary outcome will be assessed by changes in the alcohol purchase task and approach/avoidance task, which participants will complete pre- and post-NFB training. A secondary outcome is to determine whether NFB results in transfer of heightened fronto-cortical activity to improvements on general executive functioning following 8 sessions of NFB training. The secondary outcome will be assessed via changes in neurocognitive tasks assessing behavioural inhibition, risky decision making, and executive functioning, all of which will be administered pre- and post-NFB training.
