Recent status scores for version 6 of the Addiction Severity Index (ASI‐6)

Abstract

Aims To describe the derivation of Recent Status Scores (RSSs) for Version 6 of the Addiction Severity Index (ASI-6). Design 118 ASI-6 recent status items were subjected to nonparametric item response theory (NIRT) analyses followed by confirmatory factor analysis (CFA). Generalizability and concurrent validity of the derived scores were determined. Setting and Participants 607 recent admissions to variety of substance abuse treatment programs constituted the derivation sample; a subset (N = 254) comprised the validity sample. Measurements The ASI-6 interview and a validity battery of primarily self-report questionnaires that included at least one measure corresponding to each of the seven ASI domains were administered. Findings Nine summary scales describing recent status that achieved or approached both high scalability and reliability were derived; one scale for each of six areas (medical, employment/finances, alcohol, drug, legal, psychiatric), and three scales for the family/social area. Intercorrelations among the RSSs also supported the multidimensionality of the ASI-6. Concurrent validity analyses yielded strong evidence supporting the validity of the six of the RSSs (Medical, Alcohol, Drug, Employment, Family/Social Problems, Psychiatric). Evidence was weaker for the Legal, Family/Social Support and Child Problems RSSs. Generalizability analyses of the scales to males versus females and whites versus blacks supported the comparability of the findings with slight exceptions. Conclusions The psychometric analyses to derive Addiction Severity Index-6 Recent Status Scores (RSSs) support the multidimensionality of the ASI-6 (i.e., the relative independence of different life functioning areas), consistent with research on earlier editions of the instrument. In general, the ASI-6 scales demonstrate acceptable scalability, reliability and concurrent validity. While questions remain about the generalizability of some scales to population subgroups, the overall findings coupled with updated and more extensive content in the ASI-6 support its use in clinical practice and research.

Diferencias de género en la gravedad de la adicción

“…En el presente trabajo sólo se muestran los datos de la visita basal de inclusión. A todos los pacientes se les administró la versión española del Addicition Severity Index (ASI-6) (Cacciola, Alterman, Habing, y McLellan, 2011;Díaz Mesa et al,2010).…”

Perceptions of treatment among offenders with mental health problems and problematic substance use: The possible relevance of psychopathic personality traits

“…All MSAC-participants who had been subjected to the PCL-R had also been interviewed with the Swedish translation of the sixth version of the Addiction Severity Index (ASI-6 [41,42]); a semi-structured interview used by various professionals and researchers to assess current and prior problematic use, problems related to such use as well as the need for treatment. The interview covers items within the following nine domains: medical, employment, alcohol, drugs, legal, psychiatric, and family/social domains, with the latter subdivided into family/social problems, family/social support and child problems.…”

“…The interview covers items within the following nine domains: medical, employment, alcohol, drugs, legal, psychiatric, and family/social domains, with the latter subdivided into family/social problems, family/social support and child problems. According to recent studies the ASI-6 has adequate psychometric properties [41,43].…”

Psichosocial addictions treatment based on matrix model in a public center: a pilot study / Tratamiento psicosocial de las adicciones basado en el modelo matrix en un centro público: un estudio piloto

“…La gravedad de la adicción se midió principalmente con la subescala de drogas del ASI6, que ha probado niveles aceptables de validez concurrente, fiabilidad test-retest y predicción de la retención según gravedad de la adicción, y se acepta como un instrumento válido y sensible al cambio terapéutico (Cacciola, Alterman, Habing y McLellan, 2011;Díaz Mesa et al, 2010). Se utilizó la subescala de drogas, en la que el paciente da una estimación de las características de su consumo de diferentes sustancias, incluido alcohol tanto en el último mes como en los últimos seis meses respecto a su frecuencia e intensidad.…”
