Psychometric properties of the DSM-5 ADHD two-factor model in emerging and older adults
The current study sought to investigate the two-factor model of attention-deficit/hyperactivity disorder (ADHD) symptoms in two distinct groups: emerging adults (N = 226; aged 18–25 years) and later adults (N = 236; aged 26–65 years) in a large community sample. Participants provided self...

| Summary: | The current study sought to investigate the two-factor model of attention-deficit/hyperactivity disorder (ADHD) symptoms in two distinct groups: emerging adults (N = 226; aged 18–25 years) and later adults (N = 236; aged 26–65 years) in a large community sample. Participants provided self-ratings of ADHD symptoms (inattention [IA], hyperactivity [HY], and impulsivity [IM]) using the Current Symptom Scale. Confirmatory factor analysis (CFA) was employed to examine the applicability of the two-factor ADHD model (factors for IA and HY/IM), while multiple-group CFA was used to assess measurement invariance across the two groups. The results indicated at least adequate support for the two-factor model. Additionally, there was strong support for measurement invariance across the two groups. Moreover, the latent factor mean scores for IA and HY/IM were higher in the emerging adults’ group. The findings hold both theoretical and practical implications, which are discussed in detail. |
