The objective of this study was to propose a structural model that delineates the relationship between different psychological characteristics in relation to mental health problems through a structural equation model. In a non-random, intentional sample of N = 231 students, the specified model demonstrates that anger-trait, self-denial and internal locus of control variables have effects on mental health problems through mediators such as anger-in, lack of assertiveness, and self-efficacy, and that they keep the expected theoretical relationships (X2 = 50.24, gl = 35 and p = 0.04; razón X2/gl = 1.44, CFI = .98, NFI = .93, IFI = .98, RMSEA = .04) These findings are discussed in terms of their contribution to understanding the mechanisms of the complex relationship among psychological characteristics, personality and health.

The goal of this study was to explore the psychometric properties of a Spanish version of the Type D Personality Scale (DS-14) in a sample of Mexican participants (n = 702). The scale was evaluated through a non-parametric approach based on Mokken scaling. Moreover, confirmatory factor analyses were performed using the weighted least squares mean and variance (WLSMV) method, internal consistency estimation with omega coefficient (ω), measurement invariance by gender, and convergent validity with mental health measures (MBI = burnout, GHQ = depression, sleep disorders, social dysfunction, and somatic symptoms), and controlling job stressors (JCQ = job demands and job control). The results showed low to moderate partial correlations in DS-14 items concerning the mental health scores, and acceptable reliability rates (ω = .62-.86). Measurement invariance between men and women was found, a...
