Propiedades psicométricas y métodos de medición de la escala de autoinforme sobre el trastorno de déficit de atención e hiperactividad en adultos - tamizaje (ASRS- Tamizaje) en la población de Lima / Psychometric properties and measurement methods of the Adult Attention and Hyperactivity Disorder Self-Report Scale Screener (ASRS-Screener) in the population of Lima

RESUMEN Objetivos : Determinar la distribución de puntajes, confiabilidad, validez y asociación con variables sociodemográficas de la Escala de Autoinforme sobre el Déficit de Atención e Hiperactividad en Adultos-Tamizaje (ASRS-Tamizaje) en la población de Lima y Callao, según dos formas de calificación (binaria y Likert), y establecer la concordancia entre ambas. Material y Métodos : Se realizó un análisis secundario de la base de datos del Estudio Epidemiológico de Salud Mental de Lima Metropolitana y Callao 2012 - Replicación, en una muestra de 4445 personas de 18 o más años de edad (42,6±17,4). Resultados : El promedio de la ASRS-Tamizaje en escala Likert fue 3,74+3,9 (rango 0-21), la consistencia interna mediante coeficiente alfa de Cronbach =0,806 y mediante el coeficiente omega de McDonald =0,869; el análisis factorial mostró que 52,95% de la inercia total era explicado por un solo factor. En escala binaria la media fue 0,89+1,27 (rango 0-6), el alfa de Cronbach =0,599, el omega de McDonald =0,753 y el 52,31% de la inercia fue explicado por dos factores. Con ambas escalas, se halló un coeficiente Kappa =0,734 de concordancia de tamizajes positivos. Las dos formas de la escala se asocian con la edad, en tanto que solo la clasificación binaria lo hace con estado civil y grado de educación. Conclusiones: La ASRS-Tamizaje es un instrumento de consistencia interna aceptable. Su estructura factorial y la prevalencia de tamizajes positivos varían según la forma de medición (Likert o binaria).

SUMMARY Objectives: To determine the distribution of scores, reliability, validity and association with sociodemographic variables of the Self-Report Scale of Attention Deficit Hyperactivity Disorder in adults - Screening (ASRS- Screening) in the population of Lima and Callao, according to two rating scales (binary and Likert), and to establish the concordance between both of them. Material and Methods : Study based on data from the Epidemiological Mental Health Study of Metropolitan Lima 2012 - Replication, in a sample of 4 445 people, 18 years or older (42.6 ± 17.4). Results : The average of the ASRS-Likert screening was 3.74 + 3.9 (range 0-21), internal consistency using Cronbach alpha coefficient = 0.806, McDonald's omega coefficient = 0,869, and factor analysis showed 52.95% of the total inertia explained by a single factor. In binary scale. mean = 0.89 + 1.27 (range 0-6), Cronbach alpha = 0.599, McDonald's omega=0,753, and 52.31% of the inertia was explained by two factors. With both scales, Kappa coefficient showed 0.734 of concordance of positive screenings. The two forms of qualification are associated with age whereas only binary classification was with marital status and educational level. Conclusions : ASRS-Screening is an instrument of acceptable internal consistency. Its factorial structure and the prevalence of positive screenings vary in accordance with the Likert or binary measurement form.

Clinical Utility of the Korean Version of the WHO Adult Attention-Deficit/Hyperactivity Disorder Self-Report Scale Screener

OBJECTIVE: The aim of this study was to compare the performance of the 18-item Korean version of the World Health Organization adult attention-deficit/hyperactivity disorder self-report scale (ASRS) with the six-item ASRS Screener for predicting attention-deficit/hyperactivity disorder (ADHD) group. METHODS: The study sample included 51 adult patients with ADHD and 158 normal controls. All participants completed the ASRS and were interviewed individually using the Mini-International Neuropsychiatric Interview. Receiver operating characteristic (ROC) curves were used to compare the ASRS (ASRS-18) with the ASRS Screener (ASRS-6) in Korean samples. RESULTS: The ADHD group had higher ASRS and ASRS subscale scores than those of the control group. ROC curve analysis revealed the ASRS was more powerful to predict ADHD group than the ASRS Screener, but the ASRS Screener also had strong concordance with clinician diagnoses. CONCLUSION: This study shows that the 18-question ASRS outperforms the six-question ASRS Screener. However, the weighted Screener is also a valid and useful screening instrument both in epidemiological surveys and in clinical settings.

The WHO Adult ADHD Self-Report Scale: Reliability and Validity of the Korean Version

OBJECTIVE: A self-report scale of adult attention-deficit/hyperactivity disorder, the World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS) was developed and demonstrated good psychometric properties. The purpose of the present study is to investigate the psychometric properties of the ASRS in Korean samples. METHODS: The ASRS includes 18 questions regarding the frequency of recent DSM-IV Criterion A symptoms of adult ADHD. We examined the factor structure, internal consistency, and convergent validity of the ASRS in Korean samples. RESULTS: The ASRS demonstrated good internal consistency and test-retest reliability. Correlations between the ASRS and other adult ADHD measures were high, providing evidence of convergent validity. A subsequent exploratory factor analysis indicated that a two-factor solution provided the best fit. CONCLUSION: It is expected that this scale would be helpful in clinical settings and research in Korea.

History of childhood Attention Deficit Hyperactivity Disorder (ADHD) among adult substance users in selected drug rehabilitation centers: A descriptive study

OBJECTIVES: This study aims to determine the prevalence of ADHD among substance users in selected rehabilitation centers admitted from September 1,2008 to October 31,2008 using the Wender-Utah Rating Scale (WURS) and Adult ADHD Self-Report Scale (ASRS).METHODOLOGY: A total of 104 recovering adult substance users (CI 95%) from rehabilitation centers were included by purposive sampling. They were then asked to answer an information set and subsequently WURS & ASRS was administered, either self-administered or clinician-assisted.RESULTS: In this study, the prevalence of childhood ADHD among adult substance users using WURS was 23.1%. Of the 80 (77.1%) who didn't reach the cut-off score of 46, twenty-one subjects (20.2%) had WURS scores between 39-45 may have possible ADHD. About 29 (27.9%) subjects showed adult symptoms of ADHD. However, substance users with atypical depression and borderline personality disorder were not screened out and may account for false positive results.CONCLUSION: About 1/3 of substance users in the study were positive for ADHD using the WURS while 1/5 of those studied had possible ADHD, needing further investigation.
