Psychological strain (Psychische Beanspruchung) is defined according to DIN EN ISO 10075-1 as "the immediate (not long-term) effect of psychological stress on the individual depending on their respective enduring and momentary prerequisites".
The Balance Principle
Strain arises from the interplay of:
- Stress (external factors)
- Individual resources (competence, experience, constitution)
Same stress = different strain!
Positive Strain Consequences
- Warm-up/activation
- Practice and learning effects
- Competence acquisition
- Flow experience
Negative Strain Consequences
Short-term:
- Fatigue
- Monotony
- Satiation
- Stress
Long-term:
- Exhaustion
- Burnout
- Mental disorders
- Physical complaints
Factors Influencing Strain
- Qualification and experience
- Personality and coping strategies
- Current health status
- Social support
- Recovery opportunities
Significance for Risk Assessment
Psychological risk assessment primarily captures stress. However, individual strain factors should also be considered when developing measures.
