A novel framework of stress management competencies: construct validity of the psychological immune system model
摘要
Despite extensive research into stress management, there is still no comprehensive model for detailing the factors that buffer its negative impact. The psychological immune system model is a new, integrative approach that enables a more precise understanding of the structure of personal resources when exposed to stress. This study sought to extend research on the construct validity of psychological immunity in relation to resilience, personality traits, psychological stress and mental health burden. A cross-sectional research design was used with a sample of 577 adults from the general population, aged 18 to 50 years. The construct validity was assessed using correlational and several linear regression analyses. In addition, between-group comparisons were conducted to examine differences in the severity of nine psychopathological symptoms across subgroups with low and high psychological immunity. The results supported the hypotheses that psychological immunity is associated with resilience-related personality traits and functions as a protective factor against perceived stress, mental health burden and a number of psychopathological symptoms. In addition, significant differences were found across all psychopathology scales, consistent with the hypothesis that individuals with high psychological immunity are less vulnerable to mental health burden. These findings highlight the potential of the psychological immune system model as a framework for identifying vulnerability and guiding preventative interventions. However, the cross-sectional self-report design limits causal interpretations and generalizability. Overall, the findings support the construct validity of psychological immunity and provide further evidence that the Slovak version of the Psychological Immune Competence Inventory is an appropriate instrument for assessing stress management competencies. This research is embedded within a broader study registered with ClinicalTrials.gov (Identifier NCT07070180).
