Theoretical model for ADHD symptom–cognition relationships and the factor structure of the ASRS.
A) The theoretical model for ADHD symptom–cognition relationships examined in multi-group SEM analysis. Demographic variables include gender, age and education. Anxiety and depression symptom measures are indicated as the mental health variable in the diagram. B) and C) Models representing the ASRS factor structure in MA cohort (B) and OA cohort (C). Standardised factor loadings and covariance between the latent factors – Inatt and Hyperact are shown. Arrows reflect direction of relationships between variables.
Figure 2.
Final model for ADHD symptom–cognition analyses for MA cohort.
Only paths significant at p<0.01 are shown. Arrows reflect direction of relationships between variables. Standardised regression coefficients are shown. Factor loadings and covariance between the latent factors – Inatt and Hyperact, which were constrained equal across groups in the analyses, and correlation between cognitive test measures are not shown for the sake of simplicity. I: item; gen: gender; educ: education; Inatt: latent factor Inattention; Hyperact: latent factor Hyperactivity; DEP: depression symptom measure; ANX: anxiety symptom measure; STW: Spot-the-Word Test; TMT-A: Trail Making Test A; TMT-B: Trail Making Test B; SDMT: Symbol-Digit Modalities Test; CRT: Choice Reaction Time; DR: Delayed Recall; DSB: Digit Span Backwards.

Final model for ADHD symptom–cognition analyses for OA cohort.
Only paths significant at p<0.01 are shown. Arrows reflect direction of relationships between variables. Standardised regression coefficients are shown. Factor loadings and covariance between the latent factors – Inatt and Hyperact, which were constrained equal across groups in the analyses, and correlation between cognitive test measures are not shown for the sake of simplicity. I: item; gen: gender; educ: education; Inatt: latent factor Inattention; Hyperact: latent factor Hyperactivity; DEP: depression symptom measure; ANX: anxiety symptom measure; STW: Spot-the-Word Test; TMT-A: Trail Making Test A; TMT-B: Trail Making Test B; SDMT: Symbol-Digit Modalities Test; CRT: Choice Reaction Time; DR: Delayed Recall; DSB: Digit Span Backwards.
