  • Description: Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms of inattention (IA) and hyperactivity/impulsivity (HI) were examined in relation to three personality instruments: Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ); the Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scales; and the Multidimensional Personality Questionnaire-Brief (MPQ-BF) (N= 214). Results showed that IA was associated positively with Sensitivity to Punishment (in the SPSRQ), Negative Emotionality (in the MPQ-BF), and Behavioral Inhibition System (in the BIS/BAS scales). HI was associated positively with Sensitivity to Reward (in the SPSRQ), Reward Responsiveness and Drive (both in the BIS/BAS scales), and Positive Emotionality (in the MPQ-BF). Both IA and HI were associated negatively with Constraint (in the MPQ-BF), and HI was associated positively with Fun Seeking (in the BIS/BAS scales). These findings are interpreted in terms of the original and revised reinforcement sensitivity theories. © 2010.

  • Description: OBJECTIVE: ADHD and Hyperkinetic Disorder (HKD) have the same 18 symptoms, covering inattention (IA), hyperactivity (HYP), and impulsivity (IMP). This study was aimed at providing descriptive scores for the different symptom groups in these disorders and how these scores varied by age and gender, the percentages of individuals meeting the symptom thresholds for the different ADHD types and HKD, the factor structure, and gender invariance of these symptoms in adults. METHOD: To accomplish this, 852 adults provided self-ratings for a scale comprising the 18 ADHD/HKD symptoms. RESULTS: The findings showed that age and gender had minimal effects on the ADHD symptoms. Also, in terms of symptom counts, 2% had HKD and 6.3% had ADHD (inattentive = 1.6%, hyperactive-impulsive = 2.7%, and combined type = 2.0%). Confirmatory factor analysis (CFA) provided most support for the three-factor HKD model, involving separate factors for the IA, HYP, and IMP symptoms. This model showed full measurement invariance across gender. CONCLUSION: The theoretical and clinical implications of the findings are discussed.

  • Description: Objective: This study used confirmatory factor analysis to examine the factor structure for the 10 core WISC-IV subtests in a group of children (N = 812) with ADHD. Method: The study examined oblique four- and five-factor models, higher order models with one general secondary factor and four and five primary factors, and a bifactor model with a general factor and four specific factors. Results: The findings supported all models tested, with the bifactor model being the optimum model. For this model, only the general factor had high explained common variance and omega hierarchical value, and it predicted reading and arithmetic abilities. Conclusion: The findings favor the use of the FSIQ scores of the WISC-IV, but not the subscale index scores. © 2016 Gomez, Vance and Watson.

ADHD and personality : A meta-analytic review

  • Reviewed:
  • Description: We report a meta-analysis of up to 40 data sets that examined the personality dimensions in the Five-Factor Model (FFM) and the integrated Five-Factor Model (IFFM) in relation to ADHD symptom domains of inattention (IA) and hyperactivity/impulsivity (HI). The IFFM incorporated the dimensions of other personality models (in particular, those of Eysenck, Tellegen, and Cloninger, as well as the FFM). Major findings were: (1) IA and HI were both associated with low conscientious inhibition/conscientiousness, and low agreeable inhibition/agreeableness, and with high negative emotionality/neuroticism; (2) conscientious inhibition and conscientiousness were more strongly related to IA than HI; (3) agreeable inhibition and agreeableness were more strongly related to HI than IA; and (4) the association of conscientious inhibition and conscientiousness with HI was moderated by age group and source from where participants were recruited (associations were stronger in children than adults, and clinical samples than community samples). These findings are discussed in relation to single and multiple pathway theories, underlying factors and processes for the personality-ADHD link, and clinical implications.

  • Description: Objective: Generalized partial credit model, which is based on item response theory (IRT), was used to test differential item functioning (DIF) for the Diagnostic and Statistical Manual of Mental Disorders (4th ed.), inattention (IA), and hyperactivity/impulsivity (HI) symptoms across boys and girls. Method: To accomplish this, parents completed an ADHD rating scale for 403 boys and 380 girls, between 6 and 11 years of age. Results: The findings indicated no DIF for all the slope parameters for both the IA and HI symptoms. For location parameters, there was no DIF for all the IA symptoms and for seven of the nine HI symptoms. However, the effect sizes for the DIF symptoms were small. Thus, there was good support for gender equivalency for the ADHD symptoms. Conclusion: These findings extend existing data on gender equivalency of ADHD symptoms, obtained using other methodologies for testing measurement equivalency.

  • Description: Objective: To examine the factor structure of the Sleep Disorder Scale for Children (SDSC) in children and adolescents with attention deficit and hyperactivity disorder (ADHD). Method: The caregivers of 307 children with ADHD completed the SDSC. Standard and bifactor confirmatory factor analysis (CFA) evaluated the goodness-of-fit of competing factor structures. Results: The original and unidimensional factor structure produced sub-optimal fit. Bifactor exploratory factor analysis (EFA) was performed to examine the underlying structure of the SDSC. A revised bifactor solution comprising six-specific factors and a general factor was identified. A nested version of this model was deemed to be the preferred model, which also demonstrated good psychometric properties. Conclusion: There is evidence of a ‘general sleep difficulties’ factor in children with ADHD. Four of the six original factors were replicated in this study. However, the revised factor structure suggests that clinicians should be cautious of the utility of subscale scores pending further validation in ADHD samples. © 2019

  • Description: Receiver operating characteristic curve analysis was used to examine and compare the diagnostic accuracy of the Conners 3–Parent Short Form (C 3-P(S)), and the Conners 3–Teacher Short Form (C 3-T(S)) inattention and hyperactivity/impulsivity scales, and the Child Behavior Checklist (CBCL) and Teacher’s Report Form (TRF) attention problems scales, to distinguish those with and without attention deficit/hyperactivity disorder (ADHD). It also examined and compared the diagnostic accuracy of the C 3-P(S) and C 3-T(S) Aggression (AG) scales, and the CBCL and TRF Aggressive Behavior (AB) scales, to distinguish those with and without oppositional defiant disorder (ODD). The study used archival data (N = 150-261) involving a large group of clinic-referred children aged between 6 and 11 years who had been interviewed for clinical diagnosis of ADHD and ODD using the Anxiety Disorders Interview Schedule for Children (ADISC-IV) as the reference standard, and then administered one or more of the screening measures. The findings provided empirical support for the use of the C 3-P(S) and CBCL for identifying ADHD and ODD, with the CBCL aggressive behavior scale having better ability to detect ODD. The implications of the findings for using the screening scales for diagnoses of ADHD and ODD are discussed. © The Author(s) 2019.

  • Description: Attention Deficit/hyperactivity disorder (ADHD) is conceptualized differently in the Diagnostic and Statistical Manual (DSM-5), the International Classification of Diseases-10 (ICD-10), and the Hierarchical Taxonomy of Psychopathology (HiTOP) frameworks. This study applied independent cluster confirmatory factor analysis (ICM-CFA), exploratory structure equation model with target rotation (ESEM), and the S-1 bi-factor CFA approaches to evaluate seven ADHD models yielded by different combinations of these taxonomic frameworks. Parents and teachers of a community sample of children (between 6 and 12 years of age) completed the Disruptive Behavior Rating Scale (for ADHD symptoms) and the Strengths and Difficulties Questionnaire (for validation). Our findings for both parent and teacher ratings provided the most support for the S-1 bi-factor CFA model comprised of (i) a g-factor based on ICD-10 impulsivity symptoms as the reference indicators and (ii) inattention and hyperactivity as specific factors. However, the hyperactivity-specific factor lacked clarity and reliability. Thus, our findings indicate that ADHD is best viewed as a disorder primarily reflecting impulsivity, though with a separable inattention (but no hyperactivity) component, i.e., “ADID (attention deficit/impulsivity disorder).” This model aligns with the HiTOP proposals. © Copyright © 2021 Gomez, Liu, Krueger, Stavropoulos, Downs, Preece, Houghton and Chen.

  • Description: The study examined how dimensions of Whiteside and Lynam's (2003) UPPS-P model of impulsivity (lack of premeditation, lack of perseverance, negative urgency, and positive urgency) were associated directly and interactively with the attention-deficit/hyperactivity disorder (ADHD) dimensions of inattention and hyperactivity/impulsivity in men and women separately. A total of 550 adults (men = 147, women = 403), ages ranging from 18 to 65 years, from the general community completed questionnaires covering the study variables. For women, there was support for the additive model for the prediction of inattention, and both inattention and hyperactivity/impulsivity were predicted by lack of premeditation × positive urgency. For men, inattention was predicted by lack of premeditation × negative urgency, and lack of premeditation × positive urgency. In all instances, low levels of premeditation reduced the relationships between the urgency dimensions and ADHD dimensions. The theoretical and clinical implications of the findings are discussed. © 2023 The Author(s)
