Validity and Reliability of the Abbreviated Barratt Impulsiveness Scale in Spanish (BIS-15S)*

Abstract

Objective-This study determined the validity and reliability of a new, abbreviated version of the Spanish Barratt Impulsiveness Scale (BIS-15S) in Colombian subjects. Method-The BIS-15S was tested in non-clinical (n=283) and clinical (n=164) native Spanishspeakers. Intra-scale reliability was calculated using Cronbach's α, and test-retest reliability was measured with Pearson correlations. Psychometric properties were determined using standard statistics. A factor analysis was performed to determine BIS-15S factor structure.Results-447 subjects participated in the study. Clinical subjects were older and more educated compared to non-clinical subjects. Impulsivity scores were normally distributed in each group. BIS-15S total, motor, non-planning and attention scores were significantly lower in non-clinical vs. clinical subjects. Subjects with substance-related disorders had the highest BIS-15S total scores, followed by subjects with bipolar disorders and bulimia nervosa/binge eating. Internal consistency was 0.793 and test-retest reliability was 0.80. Factor analysis confirmed a three-factor structure (attention, motor, non-planning) accounting for 47.87% of the total variance in BIS-15S total scores.Conclusions-The BIS-15S is a valid and reliable self-report measure of impulsivity in this population. Further research is needed to determine additional components of impulsivity not investigated by this measure.

Half-Year Retest-Reliability of the Barratt Impulsiveness Scale–Short Form (BIS-15)

“…Scores of the BIS-15 are highly correlated with the full version, suggesting that it may be used as an alternative to the full version without losing a significant amount of information (Spinella, 2007). Psychometric properties such as factor structure, internal consistency, and validity could be replicated in German and Spanish (Meule, Vögele, & Kübler, 2011;Orozco-Cabal, Rodríguez, Herin, Gempeler, & Uribe, 2010).…”

Review of the psychometric characteristics of the Barratt Impulsiveness Scale (BIS) through its history: From the beginning until now

“…Esta versión correlacionó significativamente con la de 30 ítems (r = .94). En esta dirección, en Colombia (Orozco-Cabal, Rodríguez, Herin, Gempeler & Uribe, 2010), con una muestra de 447 individuos, se utilizaron los mismos 15 ítems. La consistencia total informada fue de α = .79.…”

Barratt Dürtüsellik Ölçeği Kısa Formu (BIS-11-KF) Türkçe Uyarlama Çalışması

“…Bulgularımızın karşılaştırma imkanı olması açısından, yakın zamanda kısa form çalışması yapan Spinella'nın çalışmasına benzer bir yöntem oluşturulmuş ve kullanılmıştır (2). Almanya ve Kolombiya çalışmalarında da aynı benzerlikte oluşturulan yapının desteklendiği görülmektedir (12,13).…”

“…Daha önce bu amaçla 15 maddelik kısa formunun psikometrik özellikleri İngilizce/Amerika Birleşik Devletleri (2), İspanyolca/Kolombiya (12) ve Almanca/Almanya (13) dillerinde çalışılmıştır. Bu sayede araştırmacıların, epidemiyolojik ve özellikle yüksek katılımlı saha çalışmalarında, klinik olmayan gruplarda ve klinik olarak; çeşitli psikiyatrik ve/veya psikiyatrik dışı hasta gruplarında yapılacak çalışmalarda kısa formunu kullanabilmesi amaçlanmıştır.…”
