ABSTRACT

OBJETIVO: Adaptar el cuestionario PCAS (del inglés Primary Care Assessment Survey) al idioma español y determinar su validez y su fiabilidad cuando se trata de identificar las debilidades y las fortalezas que se observan en la atención primaria de salud (APS). MÉTODOS: Estudio de adaptación y validación de un cuestionario-encuesta. Se seleccionó una muestra por conveniencia de 244 usuarios de servicios de APS, mayores de 18 años y con al menos dos visitas institucionales al momento de ser incluidos en el estudio. Se utilizaron las variables: accesibilidad, continuidad, integralidad, integración, interacción clínica, trato interpersonal y confianza. Se validaron la apariencia, mediante análisis de distribución de las respuestas, análisis de participación y patrones de no respuesta; el constructo, mediante análisis factorial exploratorio usando el método de componentes principales y rotación Varimax; el criterio, mediante el coeficiente de correlación de Pearson, y la fiabilidad, usando el alfa de Cronbach y el coeficiente de correlación intraclase. RESULTADOS: En el análisis factorial exploratorio se obtuvieron 11 factores que explicaron 68,38 por ciento de la variabilidad original. La validez de criterio mostró una correlación adecuada entre la medida resumen de la escala y las variables "ad hoc" Q33b (valor de r×1×2 = 0,569; P = 0,01) y Q32 (valor de r×1×2 = 0,600; P = 0,01). La escala obtuvo un coeficiente de alfa de Cronbach de 0,94. La fiabilidad test-retest (F [1,140] = 0,155 [P = 0,694]) demostró que la escala es estable en el tiempo. CONCLUSIONES: Las propiedades psicométricas de la versión adaptada del cuestionario PCAS permiten afirmar que se trata de una escala válida y fiable para evaluar la atención primaria desde un enfoque de continuidad asistencial basada en la relación médico-paciente.


OBJECTIVE: Adapt the Primary Care Assessment Survey (PCAS) questionnaire to the Spanish language and determine its validity and reliability in identifying strengths and weaknesses in primary health care (PHC). METHODS: Study of the adaptation and validation of a questionnaire-survey. The suitable sample selected was 244 users of PHC services. The users were over 18 years of age and had had at least two institutional visits prior to being included in the study. The variables used were access, continuity, comprehensiveness, integration, clinical interaction, interpersonal treatment, and trust. Participation was confirmed through analysis of the distribution of responses; participation and patterns of nonresponse; the construct, through exploratory factorial analysis, using principal component analysis and the varimax rotation; the criterion, through the Pearson product-moment correlation coefficient; and reliability using Cronbach's alfa and the intraclass correlation coefficient. RESULTS: The exploratory factorial analysis obtained 11 factors that explain 68.38 percent of the original variability. The criterion validity showed a sufficient correlation between the summary measure of the scale and the ad hoc variables Q33b (value of r x1x2 = 0.569; P = 0.01) and Q32 (value of r x1x2 = 0.600; P = 0.01). The scale obtained a coefficient of Cronbach's alfa of 0.94. The test-retest reliability (F [1 140] = 0.155 [P = 0.694]) demonstrated that the scale is stable over time. CONCLUSIONS: The psychometric properties of the adapted version of the PCAS questionnaire make it possible to state that it is a valid and reliable scale to evaluate primary care from a standpoint of ongoing care based on the physician-patient relationship.
