    Background It is essential to have a validated instrument to measure craving for cocaine use. The study’s objective was to understand the dimensionality and homogeneity of the Cocaine Craving Questionnaire (CCQ-N-10) among Colombian cocaine users. Methods A sample of 102 hospitalized or outpatient adults diagnosed with cocaine use disorders attending addiction units in Bucaramanga, Colombia. Internal consistency and construct validity were estimated by confirmatory factor analysis and correlation analysis with scales with similar objectives. Results An omega coefficient of 0.93 was obtained, and adjustment indicators of the confirmatory model were acceptable (RMSEA of 0.08, CFI and TLI of 0.99) when two of the original scale items were removed from the original scale analysis. Conclusion This study shows that the craving scale reduced to eight items can be helpful to assess the construct in the Colombian population; however, the small sample size makes it challenging to carry out other analysis to corroborate its psychometric properties.

    Objetivo: determinar la validez y confiabilidad de la Entrevista de Percepción de Carga del Cuidado de Zarit, versión de 22 ítems en español, con cuidadores familiares de personas con enfermedades crónicas en Colombia. Materiales y métodos: estudio metodológico de corte transversal, con 652 cuidadores familiares de personas con enfermedades crónicas, residentes en las cinco regiones de Colombia, con el fin de establecer la validez de constructo, con un análisis factorial y la confiabilidad a través de la consistencia interna determinando el alfa de Cronbach. Resultado: respecto a la validez de constructo, el estudio reporta a partir de la asociación libre de la rotación Varimax la carga total, y en sus dimensiones que incluyen carga interpersonal, impacto del cuidado, y las competencias y expectativas sobre el cuidado. Las cargas factoriales corresponden a los ítems planteados para medir cada una de las dimensiones propuestas. Conclusión: el instrumento Entrevista de Percepción de Carga del Cuidado de Zarit, versión de 22 ítems en español, es una herramienta de fácil aplicación y comprensión en población colombiana de diferente nivel educativo, socioeconómico y cultural; además, mostró ser válido y confiable para evaluar la carga del cuidado en cuidadores familiares de personas con enfermedad crónica.

    Entrevista Percepción de Carga del Cuidado de Zarit: Pruebas psicométricas para Colombia
    (2015-03-11) Barreto Osorio, Ruth Vivian; Campos de Aldana, María-Stella; Carrillo González, Gloria Mabel; Coral Ibarra, Rosa del Carmen; Chaparro Díaz, Lorena; Durán Parra, Myriam; Rosales Jiménez, Rosario; Ortiz Nievas, Vilma Tamara
    Objective: This research was designed to determine the validity and reliability of the Zarit Burden Interview, specifically the 22-item Spanish version, as an instrument to measure the burden of care perceived by family caregivers of patients in Colombia with chronic diseases. Materials and Methods: A cross-sectional study of 652 family caregivers of patients with chronic diseases who reside in five regions of Colombia was conducted to establish construct validity, with a factor analysis and internal consistency reliability measured by determining the Cronbach’s alpha value. Result: In terms of construct validity, the study reports the total loading, based on free association of a varimax rotation, and in the dimensions that include interpersonal burden, impact of care, and skills and expectations about care. The factor loadings pertain to the items introduced to measure each of the proposed dimensions. Conclusion: The results showed the 22-item Spanish version of the Zarit Burden Interview is an instrument that can be applied and understood easily in a Colombian population with different educational, socio-economic and cultural levels. It also proved to be valid and reliable for assessing the burden of care perceived by family caregivers of patients with chronic diseases.

    Psychometric Properties of an Instrument to Assess the Fear of COVID-19 in a Sample in Argentina: a Mixed Approach
    (2022-01-14) Scoppetta, Orlando; Cassiani‑Miranda, Carlos Arturo; Arismendy‑Lopez, Yinneth Andrea; Tirado‑Otálvaro, Andrés Felipe; Neurociencias
    The FCV-19S was the frst instrument designed to assess the severity of fear related to COVID-19 and has already been validated in many languages. The objective of this study was to evaluate the homogeneity and construct validity of the 5-item version of the FCV19S, using an online questionnaire in 599 people. The participants’ age ranged from 18 to 65 years. Age, gender, marital status, educational level, employment status, and socioeconomic status were analyzed. In the evaluation process we assessed interitem correlation, item rest-correlation, confrmatory factor analysis: Root Mean Square Error of Approximation, Comparative Fix Index, Tucker-Lewis Index; internal consistency (Cronbach’s alpha, McDonald’s omega), and the Rasch model was assessed for learning more about the psychometric properties of the scale, which allows a detailed knowledge of the strengths and weaknesses of a scale. The FCV-5S has adequate psychometric indicators from the perspective of the Classical Theory of Items. The major limitations were using a self-reported measure and having a convenience sample not necessarily representative of the general population of Argentina.
