[The correlations between psychological indices and cardiac variance]

Area of Science:

• Occupational health
• Psychophysiology
• Industrial psychology

Background:

• Prolonged occupational exposure to stress can impact both physiological and psychological well-being.
• Understanding the interplay between physiological indicators and psychological states is crucial for managing workplace health.

Purpose of the Study:

• To investigate correlative links between cardiac variance indicators and psychological parameters in individuals exposed to stressful occupations.
• To explore the relationships between physiological and psychological levels in airline transportation and chemical industry workers.

Main Methods:

• The study involved three groups: airline traffic managers (57), chemical plant workers (14), and chemical plant operators (14).
• Measured cardiac variance indicators included mean heart rate intervals, standard deviation (SD), amplitude of the mode (AMo), homeostatic index (HI), and spectral power related to thermoregulation (Pt) and respiration (Pp), and index of centralization (IBO).
• Assessed psychological parameters such as extroversion, introversion, neuroticism, psychoticism, interpersonal conflicts, self-control, social support, self-confidence, work satisfaction, and psychosomatic complaints.

Main Results:

• Significant and highly significant correlative links were identified between various cardiac variance indicators and psychological parameters.
• Specific relationships were observed between physiological stress markers and psychological traits in the studied occupational groups.

Conclusions:

• Evidence suggests a connection between physiological responses (cardiac variance) and psychological states in individuals subjected to lengthy, stressful occupational demands.
• These findings highlight the psychophysiological impact of occupational stress in demanding industries like aviation and chemical manufacturing.
