Background. Gratitude is a human strength that promotes well-being; however, it is important to consider culture when constructing scales. 

Objective. To develop and validate a culturally adapted Mexican Gratitude Scale for youth, establishing its psychometric properties: reliability, internal structure, convergent validity, and criterion validity.

Design. The participants were 442 Mexican young people with a mean age of 20.81 years from three regions of Mexico.

Results. The initial 28-item scale underwent systematic refinement through Confirmatory Factor Analysis (CFA). This psychometric validation process yielded a final 9-item instrument characterized by a robust two-dimensional factorial structure: personal gratitude and emotional gratitude. The CFA results confirmed this structure through excellent model fit indices (CFI = .98; NFI = .97) and demonstrated significant internal consistency for personal gratitude (ω = .89) and emotional gratitude (ω = .88). The scale provided evidence for convergent validity through significant correlations. Personal gratitude showed moderate associations with optimism (r = .40), positive vision (r = .37), affective resources (r = .30), and hope (r = .43), while emotional gratitude exhibited stronger relationships with optimism (r = .54), positive vision (r = .51), affective resources (r = .42), and hope (r = .52). Discriminant validity was evidenced by young people who do not report any type of mental disease scoring higher on gratitude.

Conclusion. The psychometric properties of the Mexican Gratitude Scale proved to be acceptable, facilitating its use and application in the general and clinical population for future research.

Background. The diagnosis and treatment of colorectal cancer are considered highly stressful and potentially traumatic events that can generate post-traumatic stress symptoms and distress among patients.

Objective. This study assessed levels of post-traumatic stress symptoms, distress, and optimism, as well as differences between these conditions relative to sociodemographic and medical variables, in Mexican patients with colorectal cancer.

Design. A cross-sectional descriptive study design was employed, in which 192 colorectal cancer patients over the age of 18 years participated. They filled out the following questionnaires in person: a sociodemographic and medical data questionnaire; the Event Impact Scale-Revised (EIE-R); the Hospital Anxiety and Depression Scale (HADS); and the Life Orientation Test (LOT-R).

Results. The results showed that 32.3% of the patients reported post-traumatic stress symptomatology, and 21.4% reported distress. Post-traumatic stress symptoms and distress varied according to age and monthly income. Significant differences between the sexes were also observed in the levels of post-traumatic stress symptoms and distress. Post-traumatic stress was positively and significantly related to distress, and negatively and significantly to optimism.

Conclusion. Based on these data, we concluded that a significant percentage of colorectal cancer patients present high levels of post-traumatic stress symptoms as well as distress, and that these levels may vary according to sociodemographic and medical characteristics.
