Dimensionalidad de un ítem único de preocupación por el cáncer mediante modelos de ecuaciones estructurales

The study aims to analyze the influence of the latent variable cancer concern (PPC) on the measurement of the single item Cancer Worry Chart (CWC) through the method of structural equations (SEM). 165 healthy adults with a family history of cancer participated (Mage = 40.25 years; SD = 12.99), who attended the outpatient clinic of health institutions in Peru. The CWC has a predominance of responses that express less concern about cancer (M = 2.27; SD = .98). The use of SEM reports very good adjustment rates for the model (SB-χ2 = .0051; gl = 1; p = .943; CFI = 1.00; RMSEA [IC90%] = .00 [.00, .04]; SRMR = .007), with a factor load of .949 and communality of .90. The PPC construct explains 90% of the variability of the CWC scores. This finding provides complementary evidence of CWC construct validity.El estudio tiene como objetivo analizar la influencia de la variable latente preocupación por el cáncer (PPC) sobre la medida de ítem único Cancer Worry Chart (CWC) a través del método de ecuaciones estructurales (SEM).

El CWC presenta un predominio de respuestas que expresan una menor preocupación por el cáncer (M= 2.27; DE = .98). El uso de SEM, reporta índices de ajuste muy buenos para el modelo (SB-χ2 = .0051; gl = 1; p = .943; CFI = 1.00; RMSEA [IC90%] = .00 [.00, .04]; SRMR = .007), con una carga factorial de .949 y comunalidad de .90. El constructo PPC explica el 90% de la variabilidad de los puntajes del CWC. Este hallazgo brinda evidencia complementaria de validez de constructo del CWC

Initial psychometric evidence of a brief measure of cancer worry

Objective: The cancer worry is associated with preventive behaviors for the detection of this disease; However, there is no instrument with evidence of validity and reliability to measure this construct in Latin American countries, including Peru. The objectives of this study were to evaluate the evidence of validity based on the internal structure and reliability of the Cancer Worry Scale (CWS) ina sample of people without cancer diagnosis with a family history of cancer. Method: It counted withthe participation of 215 healthy people with a family history of cancer who attended the outpatientservice of two public and private health institutions in the city of Chimbote with an average age of42.10 years (SD = 14.05). For the collection of information, an ad hoc sociodemographic record andthe Cancer Worry Scale were used. Results: The one-dimensional model presented a good fit of the data(SBχ2 (8) = 14.39, SB χ2 / df = 1.79, CFI = 0.991, SRMR = 0.025, RMSEA = 0.061 [IC90%: 0.000-0.111], AIC = 47.701) and adequate reliability (ω corrected = 0.90; IC95%: 0.88-0.92). Conclusion: Itis concluded that the CWS presents adequate psychometric properties, being a measure that providesvalid and reliable interpretations of the cáncer worry in the peruvian context

Assessment of Obsessive Thoughts About COVID-19 in 7 Latin American Countries: Structure and Measurement Invariance of the Obsession With COVID-19 Scale

The present study aimed to evaluate the measurement invariance of the Obsession with COVID-19 Scale (OCS) among seven Latin American countries: Bolivia, Brazil, Cuba, El Salvador, Guatemala, Paraguay, and Uruguay. Although the OCS has been used in several countries and languages, there is a need for approaches that better integrate the cross-cultural equivalence of the scale. A total of 3185 people participated in the study. The results indicated the presence of a unidimensional structure and good reliability indices for the OCS in each country. The alignmentmethod indicated that the OCS is an invariant measure of COVID-19 obsession among the populations of seven Latin American countries. The findings based on IRT analysis indicated that all OCS items had adequate discrimination and difficulty parameters. The findings contribute to the understanding of the internal structure of the scale in different countries at the same time, something that has been pending evaluation.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Sociales::Instituto de Investigaciones Psicológicas (IIP
