Mental ability and psychological work performance in Chinese workers

Area of Science:

• Occupational Health
• Psychology
• Human Resources

Background:

• Workplace performance is influenced by psychological factors.
• Understanding the interplay of mental ability and occupational stress is crucial for employee well-being.
• Identifying moderators can inform targeted interventions.

Purpose of the Study:

• To investigate the relationship between mental ability, occupational stress, and psychological work performance.
• To identify factors that modify mental ability and psychological work performance.
• To provide insights into improving work performance in Chinese workers.

Main Methods:

• A study involving 485 Chinese workers (aged 33-62, 65% male) across various occupations.
• Assessment of mental ability (Mental Function Index, MFI) using memory and decoding tests.
• Measurement of occupational stress (Occupational Stress Questionnaire, OSQ) and psychological work performance.

Main Results:

• Significant differences in stress, mental ability, and performance were observed across work types and education levels (p<0.01).
• Multiple linear regression indicated mental ability (MFI) is associated with gender, age, education, and work type.
• Higher mental ability (MFI) and lower occupational stress (PSI) were linked to better psychological work performance.

Conclusions:

• Occupational stress and diminished mental ability are key predictors of suboptimal psychological work performance.
• Gender and educational level significantly modify the relationship between mental ability, stress, and work performance.
• Findings suggest targeted strategies considering individual and demographic factors are needed to enhance work performance.
