Executive Dysfunction and Functional Impairment Associated With Sluggish Cognitive Tempo in Emerging Adulthood

Area of Science:

• Psychology
• Neuroscience
• Clinical Research

Background:

• Sluggish cognitive tempo (SCT) symptoms are often comorbid with ADHD, anxiety, and depression.
• Previous research has not isolated the unique contribution of SCT symptoms to impairment when controlling for these other conditions.

Purpose of the Study:

• To determine the unique variance in functional impairment and executive function (EF) problems accounted for by SCT symptoms, after controlling for ADHD, anxiety, and depression.
• To identify which symptom set is most strongly associated with impairment.

Main Methods:

• A sample of 458 college students completed self-report measures.
• Assessed symptoms of ADHD, SCT, anxiety, and depression.
• Evaluated functional impairment and EF problems.

Main Results:

• Thirteen percent of students reported high SCT symptoms, often independent of other conditions.
• SCT symptoms uniquely explained the most variance in EF problems and functional impairment.
• High SCT symptoms, with or without high ADHD symptoms, were linked to greater impairment and EF issues.

Conclusions:

• SCT is a clinically relevant construct that requires further investigation.
• Findings highlight the importance of considering SCT in college student mental health assessments.
