    The study aimed to perform confirmatory factor analysis, internal consistency, gender differential item functioning, and discriminant validity of the Fear of COVID-5 Scale in emerging adult students of a university in Mexico. Confirmatory factor analysis, internal consistency (Cronbach's alpha and McDonald's omega), and gender differential item functioning were estimated (Kendall tau b correlation). The Fear of COVID-5 Scale showed a one-dimension structure (RMSEA = 0.07, CFI = 0.98, TLI = 0.96, and SRMR = 0.02), with high internal consistency (Cronbach's alpha of 0.78 and McDonald's omega of 0.81), non-gender differential item functioning (Kendall tau b between 0.07 and 0.10), and significant discriminant validity (Higher scores for fear of COVID-19 were observed in high clinical anxiety levels). In conclusion, the Fear of COVID-5 Scale presents a clear one-dimension structure similar to a previous study.

    Dimensionality and homogeneity of the Colombian version of the Cocaine Craving Questionnaire (CCQ-N-10)
    (2022-06-20) Cassiani-Miranda, Carlos Arturo; Scoppetta, Orlando; Quintero-Gómez, Tito Cesar; Arraut-Camargo, Eduard; Castaño-Pérez, Guillermo; Cabanzo-Arenas, Diego Fernando; Campo-Arias, Adalberto; Neurociencias
    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.

    Psychometric performance of the brief Francis scale of attitude towards Christianity (Francis-4) in Mexican university students
    (2021-05-04) Cassiani-Miranda, Carlos Arturo; Campo-Arias, Adalberto; Alvarez-Solorza, Isabel; Neurociencias
    The brief Francis scale of attitude towards Christianity (Francis-4) psychometric performance in Mexico is unknown. The objective was to evaluate the dimensionality, homogeneity, gender differential item functioning (DIF), and nomological validity of Francis-4. 1,108 university students between 18 and 60 years of age were evaluated; 80.4% were women (n = 891). CFA was performed with the following fit indicators: chi-square, RMSEA, CFI, TLI, and McDonald’s omega were calculated. For nomological validity, the mean and standard deviation according to gender were compared with Student’s t-test. Gender DIF was quantified with Kendall’s tau-b. The CFA revealed the following goodness-of-fit coefficients: chi-square = 25.45, df = 2, p = .001, RMSEA = .10, 90% CI .07 – .14, CFI = .99, TLI = .99, and SRMR = .01. Cronbach’s alpha of .97 and McDonald’s omega were .97. Scores were significantly higher in women than in men (M = 8.9, SD = 5.4 versus M = 7.6, t = 3.15, p = .002). Kendall’s tau ranged from .07 to .09 indicating absence of gender DIF. Francis-4 is a unidimensional instrument with nomological validity, high internal consistency, and absence of gender DIF. It is recommended to evaluate its performance in other populations.

    Stigmatisation associated with COVID-19 in the general Colombian population
    (2021-09-05) Cassiani-Miranda, Carlos Arturo; Campo-Arias, Adalberto; Tirado-Otalvaro, Andrés Felipe; Botero-Tobon, Luz Adriana; Upegui-Arango, Luz Dary; Rodríguez-Verdugo, María Soledad; Botero-Tobon, María Elena; Arismendy-Lopez, Yinneth Andrea; Robles-Fonnegra, William Alberto; Niño, Levinson; Scoppetta, Orlando; Neurociencias
    Background: As the COVID-19 pandemic progresses, the fear of infection increases and, with it, the stigmadiscrimination, which makes it an additional problem of the epidemic. However, studies about stigma associated with coronavirus are scarce worldwide. Aims: To determine the association between stigmatisation and fear of COVID-19 in the general population of Colombia. Method: A cross-sectional study was carried out. A total of 1,687 adults between 18 and 76 years old (M=36.3; SD=12.5), 41.1% health workers, filled out an online questionnaire on Stigma-Discrimination and the COVID-5 Fear Scale, adapted by the research team. Results: The proportion of high fear of COVID-19 was 34.1%; When comparing the affirmative answers to the questionnaire on stigma-discrimination towards COVID-19, it was found that the difference was significantly higher in the general population compared to health workers in most of the questions evaluated, which indicates a high level of stigmatisation in that group. An association between high fear of COVID-19 and stigma was evidenced in 63.6% of the questions in the questionnaire. Conclusion: Stigma-discrimination towards COVID-19 is frequent in the Colombian population and is associated with high levels of fear towards said disease, mainly people who are not health workers.

    Validity of the patient health questionnaire-2 (PHQ-2) for the detection of depression in primary care in Colombia
    (2021-01-01) Scoppetta, Orlando; Cassiani-Miranda, Carlos Arturo; Arocha-Díaz, Karen Nicolle; Cabanzo-Arenas, Diego Fernando; Campo-Arias, Adalberto; Neurociencias - UDES
    Background The PHQ-2 is a screening test for major depressive disorder (MDD) derived from PHQ-9, which has shown to be useful in the detection of cases of clinical significance in previous studies. The psychometric properties of PHQ-2 in the Colombian population are unknown. Methods PHQ-2 were assessed in 243 patients in general medical consultations using the Mini-International Neuropsychiatric Interview (MINI) as the gold standard. Internal consistency, convergent validity and criterion validity were calculated by analyzing the Receptor Operating Characteristics (ROC) and the area under the curve (AUC). Results Cronbach's alpha and McDonald's omega coefficients were 0.71. Spearman's rho coefficients for correlations with PHQ-9 and HADS-D scores were 0.63 and 0.59 (p<0.01). AUC was 0.89. The optimal cut point was ≥2 with the following indicators: sensitivity 0.87 specificity 0.74; Youden index 0.60; PPV 0.47; NPV 0.95; (LR+) 3.24; (LR-) 0.18 (95% CI 0.09-0.37). Kappa coefficient between PHQ-2 and MINI for depression was .458 and 0.46 for HADS-D. Limitations Since this study was done with people attending hospital, which could has implications for the prevalence of depression, affecting the validity indicators of the instrument. Conclusions PHQ-2 show an acceptable test performance in the context of the study. However, the test could yield a considerable amount of false positives that would require specialized evaluation to establish a reliable diagnosis.
