OBJECTIVE: To determine the construct validity of FACES III in spanish (México). DESIGN: Cross-sectional study, descriptive, confirmatory. SETTING: Mexico City, South of Federal District, Tlalpan area, divided into geo- statistical zones of a primary care unit. PATIENTS AND OTHER PARTICIPANTS: A random sample of 270 families selected in their dwellings with proportional coverage based on 17 895 dwellings of the influence area. Measurements and main results. Domicile survey applying FACES III (Family Adaptability and Cohesion Evaluation Scales) in spanish, México. Twelve criteria for evaluate the construct validity of FACES III trough confirmatory factor analysis were established by the researchers. Eight criteria were surpassing appropriately and four do not surpass the minimum values established. CONCLUSIONS: FACES III in spanish (México) is an instrument with reliability of 70% with Cronbach alfa and validity measured using confirmatory Factor Analysis. Nevertheless, we found four limitations that should be analyzed and evaluated in the planning of future studies.

Objetivo. Determinar la validez de constructo del cuestionario FACES III en español (México).Diseño. Estudio transversal, descriptivo, confirmatorio. Emplazamiento. Zona de influencia sectorizada en áreas geoestadísticas básicas (AGEB) de una unidad de atención primaria en la Delegación Tlalpan, distrito federal al sur de la Ciudad de México. Participantes. Un total de 270 familias elegidas aleatoriamente en sus viviendas de modo proporcional al tamaño de las AGEB con una base de 17.895 viviendas de la zona de influencia. Mediciones y resultados principales. Encuesta domiciliaria de la Escala de Evaluación de la Cohesión y la Adaptabilidad Familiar (FACES III) en español (México).Se establecieron doce criterios para evaluar la validez de constructo del cuestionario FACES III a través del análisis factorial confirmatorio. Ocho criterios fueron superados adecuadamente y cuatro no rebasaron los valores mínimos establecidos en el análisis factorial. Conclusiones. FACES III en español (México) es fiable (70 por ciento con el índice alfa de Cronbach) y válido. Sin embargo, se encontraron cuatro limitaciones que deben ser analizadas y evaluadas en la planeación de futuros estudios (AU)

OBJECTIVE: To determine through five methods (Cronbach's alpha, split, Guttman method, parallel and strict parallel) the confidence coefficient of FACES III, instrument validated on spanish version, and to evaluate it's consistency with these five statistical methods. DESIGN: Descriptive, cross-sectional. SETTING: Tlalpan Area, south of Federal District, México, divided into geo-statistical zones. PATIENTS AND OTHER PARTICIPANTS: A randomised sample of 270 dwellings with proportional coverage, based on 17,895 ordinary dwellings of the area. INTERVENTION: Domicile survey using FACES III (Family Adaptability and Cohesion Evaluation Scales); April-May 1995. MEASUREMENTS AND MAIN RESULTS: The confidence coefficient of FACES III spanish version was calculated using no standardised Cronbach's Alpha = 0.69; split I = 0.73 and split II = 0.66; Guttman method = 0.75; parallel = 0.69 and strict parallel = 0.53. CONCLUSIONS: Cronbach's coefficient demonstrated more advantages than the other statistical methods in relation with the ordinal measurement scale of FACES III. We suggest to take into consideration three important aspects for the correct confidence analysis of this kind of instruments: Variance analysis depending on the scale of items (F test, Friedman or Cochran) Inter-items interactions analysis (nonadditivity) and the use of the balance value as purge element of error' source. Analysis of Tukey estimate, coefficient of concordance (W) and Hotelling's T squared. It's necessary the evaluation and analysis of this aspects before the report of confidence's coefficient values whose can have hidden skew.
