Neuroticism Trait and Mental Health Among Chinese Firefighters: The Moderating Role of Perceived Organizational Support and the Mediating Role of Burnout-A Path Analysis

The Effect of Craniosacral Therapy on Blood Levels of Stress Hormones in Male Firefighter Cadets: A Randomized Clinical Trial

(1) Background: Fire department cadets preparing to become firefighters and paramedics experience high levels of stress when participating in incidents like traffic accidents and fires. Stress adversely affects health, and coping with it proves difficult. Unfortunately, there is no single method that reduces stress completely in humans. One non-invasive method for lowering stress hormone levels is craniosacral therapy. (2) Methods: Fifty-seven firefighting cadets aged 18-24 years (21.63 ± 1.41) participated in the study. They were randomly assigned to either a test group or a control group. Participants' blood levels of cortisol and CRH (corticotropin-releasing hormone) were assessed before and after the study. The study group underwent 5-week craniosacral therapy (1× per week). (3) Results: The Kruskal-Wallis test showed that the therapy group's results were statistically significant for CRH values (p-value = 0.00067) and for cortisol values (p-value ≤ 0.0001). Wilxocon and Dunn tests showed statistical significance for cortisol after CS therapy between the control and study groups (p = 0.0377), and for CRH between the control and study groups before (p = 0.00634) and after the study (p = 0.000887), and in the study group before and after the study (p = 0.0101). (4) Conclusions: The application of craniosacral therapy reduced stress hormone levels in male firefighter cadets. The results indicate that craniosacral therapy (five sessions, one per week) has an effect on the reduction of stress hormones.

Five-Factor Personality Dimensions Mediated the Relationship between Parents' Parenting Style Differences and Mental Health among Medical University Students

BACKGROUND

Previous studies have identified the relationships between parental parenting style, personality, and mental health. However, the interactive influences between mother's and father's parenting styles on personality have been examined less often. To fill the gaps, the first aim of this study was to build the relationships between parental parenting style differences (PDs) and five-factor personality dimensions. The second aim was to test the mediating effect of five-factor personality dimensions on the relationships between parental parenting style differences and mental health.

METHODS

This is a cross-sectional study conducted among medical university students, and 2583 valid participants were analyzed. Mental health was measured by the Kessler-10 scale. The Chinese Big Five Personality Inventory brief version (CBF-PI-B) was used to access five-factor personality dimensions. PD was calculated by the short form of Egna Minnen av Barndoms Uppfostran. Linear regressions were conducted to analyze the associations between PD and five-factor personality dimensions. The SPSS macros program (PROCESS v3.3) was performed to test the mediating effect of five-factor personality dimensions on the associations between PD and mental health.

RESULTS

Linear regressions found that worse mental health was positively associated with PD (β = 0.15, p < 0.001), higher neuroticism (β = 0.61, p < 0.001), lower conscientiousness (β = -0.11, p < 0.001), lower agreeableness (β = -0.10, p < 0.01), and lower openness (β = -0.05, p < 0.05). The results also supported that PD was positively associated with lower conscientiousness (β = -0.15, p < 0.01), lower agreeableness (β = -0.09, p < 0.001), lower openness (β = -0.15, p < 0.001), and lower extraversion (β = -0.08, p < 0.001), respectively. The mediating effect of agreeableness or openness was supported for the relationships between PD and mental health.

CONCLUSION

These findings remind us of the importance of consistent parenting styles between mother and father, and they also can be translated into practices to improve mental health among medical university students.

The Mediating Role of Emotion Regulation Strategies in the Relationship Between Big Five Personality Traits and Anxiety and Depression Among Chinese Firefighters

Identification of protective factors to prevent firefighters' anxiety and depression is meaningful. We explored whether emotion-regulation strategies mediate the relationship between personality traits and anxiety and depression among Chinese firefighters. Approximately, 716 Chinese firefighters were recruited and completed the Emotion Regulation Questionnaire (ERQ), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Big Five Inventory−2 (BFI-2) Scale. Results (N = 622) indicated that only negative emotionality traits could predict anxiety symptoms. Meanwhile, the multilevel mediation effect analyses showed that conscientiousness through cognitive reappraisal could reduce anxiety and depression symptoms in Chinese firefighters. Our findings clarify Chinese firefighters' underlying emotion-regulation process between personality traits and anxiety and depression. Implications, limitations, and future directions are discussed.
