RESUMO
OBJECTIVES.: To adapt the 7-item Generalized Anxiety Questionnaire (GAD-7) from English to the cultural and linguistic context of Quechua Collao and to analyze its psychometric properties in Puno, Peru. MATERIAL AND METHODS.: The GAD-7 in its original version was translated into the Collao Quechua variety and its psychometric properties were analyzed. The participants were bilingual (Spanish and Quechua), over 18 years of age and of both sexes. The exploratory factor analysis (EFA) was evaluated using parallel analysis, confirmatory factor analysis (CFA) and goodness-of-fit indices; reliability was also analyzed using McDonald's classic alpha and Omega. RESULTS.: Judges and focus group participants conducted the cultural and linguistic adaptation of the GAD-7 to Quechua Collao; the EFA reported the presence of a single factor (KMO=0.88, p=0.01); while the CFA confirmed adequate adjustments in the unifactorial model (CFI=0.994; TLI=0.991; SRMR=0.027; RMSEA=0.092), good reliability (α=0.896; ω=0.894) and was also invariant across age groups, sex, marital status and educational level. CONCLUSIONS.: The questionnaire showed validity for a unidimensional model of the GAD-7 adapted to the Collao Quechua, as well as optimal reliability and invariance by the evaluated groups. Its use could benefit anxiety research and care.Motivation for the study. Peru has the largest Quechua population; however, the measurement of anxiety is not validated in the cultural and linguistic context of the Collao Quechua variety mainly spoken in Puno. Main findings. The adaptation of the 7-item Generalized Anxiety Questionnaire (GAD-7) to Collao Quechua reported adequate internal validity, invariance, and optimal reliability. Implications. The GAD-7 adapted to Collao Quechua could be implemented in primary health care for screening for generalized anxiety symptoms.

OBJETIVOS. Adaptar del inglés al contexto cultural y lingüístico del Quechua Collao y analizar las propie-dades psicométricas del Cuestionario de Ansiedad Generalizada de 7 ítems (GAD-7) en Puno, Perú. MATERIALES Y MÉTODOS. El GAD-7 en su versión original fue traducido a la variedad del quechua Collao y se analizaron sus propiedades psicométricas, los participantes fueron bilingües (español y quechua) mayores de 18 años y de ambos sexos. Se evaluó el análisis factorial exploratorio (AFE) empleando el análisis paralelo, el análisis factorial confirmatorio (AFC) y los índices de bondad de ajuste; asimismo se analizó la fiabilidad mediante el alfa clásico y Omega de Mc Donald. RESULTADOS. Los jueces y par-ticipantes del grupo focal realizaron la adaptación cultural y lingüística del GAD-7 al Quechua Collao; el AFE reportó la presencia de un único factor (KMO=0,88, p=0,01); mientras que el AFC confirmó adecuados ajustes en el modelo unifactorial (CFI=0,994; TLI=0,991; SRMR=0,027; RMSEA=0,092), una buena confiabilidad (α=0,896; ω=0,894) y además fue invariante en grupos de edad, sexo, estado civil y grado de instrucción. CONCLUSIONES. El cuestionario presentó validez para un modelo unidimensional del GAD-7 adaptado al Quechua Collao, así como una óptima confiabilidad e invarianza por los grupos evaluados. Su uso podría beneficiar la investigación y atención de la ansiedad.
