Abstract
Objective

The characteristics of the 36 item Medical Outcome Short Form Health Study Survey (SF-36) questionnaire, designed as a generic indicator of health status for the general population, allow it to be self-administered or used in personal or telephone interviews. The main objective of the study was to compare the telephone and self-administered modes of SF-36 for a population from Girona (Spain).

Methods

A randomized crossover administration of the questionnaire design was used in a cardiovascular risk factor survey. Of 385 people invited to participate in the survey, 351 agreed to do so and were randomly assigned to two orders of administration (i.e., telephone-self and self-telephone); 261 completed both questionnaires. Scores were compared between administration modes using a paired t test. Internal consistency and agreement between modalities were analyzed by respectively applying Chronbach's alpha and intraclass correlation coefficients. The effect of the order of administration on the test-retest difference was analyzed by one-way ANOVA for repeated measurements.

Results

Physical function, physical role and social functioning received significantly lower scores when the self-administered questionnaire was used prior to the telephone survey. When the initial survey was conducted by telephone, all Chronbach's alpha coefficients (except social functioning) scored over 0.70 in the self-administered modality. The intraclass correlation coefficient ranged from 0.41 to 0.83 for the telephone-self order and from 0.32 to 0.73 for the self-telephone order. No clinically significant effect was observed for the order of application.

Conclusions

The results of the present study suggest that the telephone-administration mode of SF-36 is equivalent to and as valid as the self-administered mode.

Resumen
Objetivo

El cuestionario de salud SF-36 puede ser autoaplicado o utilizado en entrevistas personales o telefónicas. El objetivo principal de este trabajo fue comparar la aplicación telefónica del cuestionario y la versión autoaplicada en una población de Girona (España).

Métodos

Diseño cruzado y aleatorizado para la aplicación de las dos formas del cuestionario. Se asignaron dos órdenes de aplicación de las encuestas (telefónica-autoaplicada y autoaplicada-telefónica). Un total de 261 personas completaron los cuestionarios. Las comparaciones entre modos de aplicación se realizaron mediante la prueba de la t de Student para datos apareados. La consistencia interna y la concordancia entre modos de aplicación se analizaron mediante los coeficientes a de Chronbach y de correlación intraclase, respectivamente. Su utilizó un modelo lineal general para medidas repetidas para evaluar el efecto del orden de la aplicación de los cuestionarios.

Resultados

Cuando se utilizó primero el cuestionario autoaplicado, las escalas de función física, rol físico y función social resultaron en una menor puntuación. Todos los oeficientes a de Chronbach fueron superiores a 0,70, excepto para la escala de función social en la modalidad autoaplicada cuando se aplicó primero la encuesta telefónica. El rango de los coeficientes de correlación intraclase fue de 0,41 a 0,83 en la modalidad telefónica-autoaplicada y de 0,32 a 0,73 en la modalidad autoaplicada-telefónica. No se observó un efecto relevante del orden de aplicación.

Conclusiones

Los resultados de este estudio indican que la aplicación de la encuesta telefónica es equivalente e tan válida como la encuesta autoaplicada.
