Attention Deficit Hyperactivity Disorders Research Yields Important Insights on ADHD Symptoms in Emerging and Older Adults

Strategic Insights -

Researchers from Federation University Australia have made significant discoveries regarding the two-factor model of attention-deficit/hyperactivity disorder (ADHD) symptoms in emerging and older adults. A study published in Academia Mental Health & Well-Being examined the psychometric properties of the DSM-5 ADHD two-factor model in these distinct age groups. The research aimed to investigate the applicability of this model, with a focus on inattention (IA), hyperactivity (HY), and impulsivity (IM) symptoms. The study's findings provided substantial support for the two-factor model and measurement invariance across the two groups, with higher latent factor mean scores for IA and HY/IM in emerging adults.

Key Takeaways:

  • The study investigated the two-factor model of ADHD symptoms in emerging adults (aged 18-25 years) and older adults (aged 26-65 years) using a large community sample.
  • Participants provided self-ratings of ADHD symptoms using the Current Symptom Scale, with confirmatory factor analysis (CFA) employed to examine the two-factor model.
  • The research found substantial support for the two-factor model, with measurement invariance across the two groups.
  • Higher latent factor mean scores for IA and HY/IM were found in emerging adults.
  • The findings have both theoretical and practical implications, which are discussed in detail.

Statistics:

  • A total of 462 participants (226 emerging adults and 236 older adults) were included in the study.
  • The research used the Current Symptom Scale for self-ratings of ADHD symptoms.
  • Confirmatory factor analysis (CFA) was employed to examine the two-factor model.
  • Measurement invariance was assessed across the two groups using multiple-group CFA.
  • Latent factor mean scores for IA and HY/IM were compared between emerging and older adults.
