Abstract

One of the procedures used most recently with longitudinal data is linear mixed models. In the context of health research the increasing number of studies that now use these models bears witness to the growing interest in this type of analysis. This paper describes the application of linear mixed models to a longitudinal study of a sample of Spanish adolescents attending a mental health service, the aim being to investigate their knowledge about the consumption of alcohol and other drugs. More specifically, the main objective was to compare the efficacy of a motivational interviewing programme with a standard approach to drug awareness. The models used to analyse the overall indicator of drug awareness were as follows: (a) unconditional linear growth curve model; (b) growth model with subject-associated variables; and (c) individual curve model with predictive variables. The results showed that awareness increased over time and that the variable ‘schooling years’ explained part of the between-subjects variation. The effect of motivational interviewing was also significant.

Uno de los procedimientos más recientemente utilizados con datos de carácter longitudinal son los modelos lineales mixtos. Su creciente interés en investigación sanitaria se constata por un aumento de los estudios que utilizan este tipo de análisis. Este trabajo se centra en los modelos lineales mixtos aplicados a un estudio longitudinal sobre el conocimiento acerca del consumo de alcohol y otras drogas en una muestra de adolescentes españoles que inician tratamiento en un centro de salud mental. Concretamente, el objetivo principal fue comparar la eficacia de un programa de entrevista motivacional con otro estándar sobre el conocimiento de las drogas. Los modelos utilizados a fin de analizar el indicador global de conocimiento sobre drogas fueron los siguientes: (a) modelo incondicional lineal de curva de crecimiento, (b) modelo de crecimiento con variables asociadas a las personas y (c) modelo de curvas individuales con variables predictoras. Los resultados mostraron que el conocimiento incrementa con el paso del tiempo y que la escolarización explica parte de la variación entre-sujetos. En cuanto al efecto de la entrevista motivacional resultó ser significativo.
