Reliability and Validity of Self- and Other-Ratings of Symptoms of ADHD in Adults
Journal of Attention Disorders, 2011
Objective: Few studies have examined concordance between raters of ADHD symptoms in adults; there is less information on how well rating scales function in distinguishing adult ADHD from other disorders. This study examined these variables using the Conners Adult ADHD Rating Scales (CAARS). Method: The sample included 349 adults evaluated for attention problems. Correlations and kappa values were calculated using self- and observer-ratings of item-level symptoms; sensitivity, specificity, and discriminant validity of cluster scores in predicting clinician diagnoses were computed for 269 participants. Results: Item-level concordance rates ranged from slight to fair. Cluster scores demonstrated a poor balance of sensitivity and specificity in predicting ADHD diagnosis; a high percentage of participants with internalizing disorders had scores in the clinical range. Conclusion: Self-and observer- ratings on the CAARS provide clinically relevant data about attention problems in adults, b...
A new rating scale for adult ADHD based on the Symptom Checklist 90 (SCL-90-R)
European Archives of Psychiatry and Clinical Neuroscience, 2012
Attention deficit hyperactivity disorder (ADHD) in adults is increasingly recognized as a clinically important syndrome. The aim of this study was to evaluate the psychometric performance of a new scale for adult ADHD based on the widely used Symptom Checklist 90 Revised (SCL-90-R). Scale performance was assessed in a clinical study including 100 ADHD patients and 65 opiate-dependent patient controls, and in the Zurich study, an epidemiological age cohort followed over 30 years of adult life. Assessments included a ROC analysis of sensitivity and specificity, internal consistency, test-retest reliability, external validity and measurement invariance over nine testing occasions. The new scale showed a sensitivity and specificity of 75 and 54%, respectively, internal consistency over 0.8 (McDonald's omega, Cronbach's alpha), one-year test-retest reliabilities over 0.7, statistically significant and substantial correlations with two other validated self-rating scales of adult ADHD (R = 0.5 and 0.66, respectively), and an acceptable degree of longitudinal stability (i.e., measurement invariance). The proposed scale must be further evaluated, but these preliminary results indicate it could be a useful rating instrument for adult ADHD in situations where SCL-90-R data, but no specific ADHD assessment, are available, such as in retrospective data analysis or in prospective studies with limited methodical resources.

Objective: Recent publications reported that a bifactor model better represented the underlying structure of ADHD than classical models, at least in youth. The Adult ADHD Symptoms Rating Scale (ASRS) has been translated into many languages, but a single study compared its structure in adults across Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) and International Classification of Diseases (ICD-10) classifications. Method: We investigated the factor structure, reliability, and measurement invariance of the ASRS among a community sample of 1,171 adults. Results: Results support a bifactor model, including one general ADHD factor and three specific Inattention, Hyperactivity, and Impulsivity factors corresponding to ICD-10, albeit the Impulsivity specific factor was weakly defined. Results also support the complete measurement invariance of this model across gender and age groups, and that men have higher scores than women on the ADHD G-factor but lower scores ...

Purpose: To adapt and assess the validity and Reliability of the Persian Observer and Self-report Screening Versions of Conner’s Adult ADHD Rating Scales Methods: The Self-report Screening Version of the Conner’s Adult ADHD Rating Scales(CAARS-S:SV) and Observer Screening Version of the Conner’s Adult ADHD Rating Scales(CAARS-O:SV) were translated into Persian by two bilingual experts and after minor changes by an expert panel were back-translated into English and were confirmed for compatibility with the original version. The Persian version of CAARS-S:SV was completed by 80 patients with confirmed adult ADHD as well as 160 healthy adults without ADHD. The Persian version of CAARS-O:SV was completed by a family member of the patients and controls who had close observation on their behaviors. Participants in all groups repeated completing the Persian versions of CAARS-S:SV and CAARS-O:SV after two weeks. Two other instruments were completed in parallel with Persian versions of CA...

Background : ADHD is classically seen as a disease of children, although it persists in one out of two cases in adults. The diagnosis is based on a long and multidisciplinary process, involving different health professionals, leading to an under-diagnosis of adult ADHD individuals. We therefore present a psychometric screening scale for the identification of adult ADHD, in order to serve as an aid in the decision whether or not to engage in a diagnostic process.Method : We designed the scale from the DSM-5 and administered it to n=110 control individuals and n=110 ADHD individuals. The number of items was reduced using regression techniques. We then performed factor analyses and a machine-learning assessment of the predictive power of the scale.Results : Internal consistency coefficients were calculated satisfactorily for TRAQ10, with Cronbach's alpha measured at .9. The 3-factor model tested was confirmed, with standardized factor loadings greater than .53 for all items. Finall...

Background. A self-report screening scale of adult attention-deficit/hyperactivity disorder (ADHD), the World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS) was developed in conjunction with revision of the WHO Composite International Diagnostic Interview (CIDI). The current report presents data on concordance of the ASRS and of a short-form ASRS screener with blind clinical diagnoses in a community sample.Method. The ASRS includes 18 questions about frequency of recent DSM-IV Criterion A symptoms of adult ADHD. The ASRS screener consists of six out of these 18 questions that were selected based on stepwise logistic regression to optimize concordance with the clinical classification. ASRS responses were compared to blind clinical ratings of DSM-IV adult ADHD in a sample of 154 respondents who previously participated in the US National Comorbidity Survey Replication (NCS-R), oversampling those who reported childhood ADHD and adult persistence.Results. Each ASRS symptom...
Validity and Reliability of Adult ADHD Self-Report Scale Thai Version ( ASRS-V 1 . 1 TH )
2017
Background: The adult ADHD Self-Report Scale Thai version (ASRS-V1.1) (18 items) is a questionnaire for screening adult ADHD. Aim: To test the validity and reliability of the 18-question ASRS-V1.1 Thai version (ASRS-V1.1 TH) as a screening tool for adult ADHD Methods: The original 18-question ASRS-V1.1 version was translated into Thai. The process was composed of forward-translation, synthesis of the translation, and back translation. Cross cultural adaptation, field testing, and final adjustment were completed consecutively. The 18-question ASRS-V1.1 TH were sent to 1,500 parents of kindergarten and elementary school students in Bangkok, Thailand. The diagnostic interview was randomly selected for 50 parents from the positive result group and 50 parents from the negative result group. The clinical interview for confirming diagnosis was run by 3 psychiatrists who were blinded to the results and used DSM-5 ADHD criteria for diagnosis. Results: The 18-question ASRS-V1.1 TH had satisfactory internal consistency (Cronbach's alpha = 0.92: Cronbach's alpha = 0.87 for inattentive scale, Cronbach's alpha = 0.84 for hyperactive / impulsive scale). For testing the criteria validity, the questionnaire has an adequate. The AUC from the first 6 questions was 0.80 (95% CI: 0.68-0.92) while from the 18 questions was 0.71(95% CI: 0.55-0.86). Conclusions: The 18-question ASRS-V1.1TH is a psychometrically reliable and valid measure for screening adult ADHD in Thai clinical samples, especially the first 6 questions of the questionnaire.
