RESUMEN
Fundamento La concordancia de las puntuaciones de los componentes físico y mental obtenida a través del SF-36 y del SF-12 ha sido establecida en población general y muestras clínicas, pero todavía no ha sido valorada entre pacientes con adicción a drogas.

Objetivo:

Analizar como un instrumento breve del estado de salud, el SF-12, es comparable con su versión extendida, el SF-36, para valorar la calidad de vida relacionada con la salud de pacientes con trastornos adictivos en tratamiento con metadona. Pacientes, maerial y

método:

Se ha llevado a cabo un estudio transversal sobre una muestra aleatoria estratificada de 726 personas incluidas en Programas de Mantenimiento con Metadona del País Vasco. Se ha utilizado el cuestionario de salud SF-36 y se han calculado los índices sumarios físico (PCS) y mental (MCS) del SF-36 y SF-12. Se han utilizado Coeficientes de Correlación Intraclase (CCI) y modelos de regresión lineal para valorar la capacidad del componente sumario físico del SF-12 (PCS-12) para predecir los valores del PCS-36, así como los del MCS-12 para predecir las puntuaciones del MCS-36.

Resultados:

La concordancia entre el SF-12 y el SF-36, tanto respecto al componente físico (ICC=0,97) como mental (ICC=0,98) ha resultado alta, mostrando una relación lineal y positiva. Una alta proporción de la varianza del componente dísico – PCS- (R2=0,88) y mental -MCS- (R2=0,91) del Sf-36 es explicado por los correspondientes índices sumarios del SF-12.

conclusiones:

el SF-12 reproduce las puntuaciones sumarias del SF-36 sin demasiada pérdida de información cuando es utilizada en pacientes en tratamiento con metadona. El SF-12 puede ser una alternativa eficiente al SF-36 para la valoración de la calidad de vida relacionada con la salud de pacientes con trastornos adictivos y su tratamiento
ABSTRACT

Background:

The concordance of the physical and mental component summary scores of the Short Form (SF)-36 has been established using the SF-12 in general and selected patient populations but has yet to be assessed in patients with drug addiction.

Objective:

to investigate whether a shorter health status instrument, the short form (SF)-12, is comparable with its longer version, the SF-36, for measuring health-related quality of life of patients with addictive disorders in treatment with methadone.

Method:

A cross-sectional study was carried out on a stratifies random sample (n=726) of users included in the Methdone Maintenanace Programme in the Basque Country in Spain. The SF-36 Healthy Survey was used and the physical component summary (PCS) and mental component summary (MCS) of the SF-36 and SF-12 were calculated. Intrraclass correlation coefficients (ICCs) and linear regression were used to assess the ability of the SF-12 physical component summary (PCS-12 mental component summary (MCS-12)) scores to predict MCS-36 scores.

Results:

The concordance between the SF-12 and the SF-36 on both physical (ICC=0,97) and mental (ICC=0,98) component summary scores (PCS and MCS respectively) is high and the relation ship is linear and positive. Most of the variance in the SF-36 PCS (R2=0,88) and MCS (R2=0,91) can be explained by their SF-12 counterparts.

Conclusions:

the SF-12 reproduced SF-36 summary scores without substantial loss of information when used on patients undergoing methadone treatment. The SF-12 appears to be an efficient alternative to the SF-36 for the assessment of health-related quality of life patients with addictive disorders and their treatment
