The Michigan Longitudinal Study (MLS) is the longest longitudinal study following high-risk substance abuse individuals. Originally started at the University of Michigan in 1985, the first generation of participants were recruited to study the effects of substance use, poverty, and educational disadvantages on individuals and families across generations.
To study these relationships, families completed cognitive tasks in conjunction with electroencephalogram (EEG) to measure brain activity patterns during the task. Children repeated these psychophysiological tasks every 18 months to capture the changes in brain activity during development. Families completed a series of questionnaires every year to assess for baseline and changes in personality, behaviors, mental health, and family functioning. Lastly, children completed temperament trait assessment batteries involving a series of emotion-eliciting series of games and tasks are designed to measure their temperament traits.
