Individual Differences in Stress (AQA A-Level Psychology): Revision Notes
Hardiness
What is hardiness?
Hardiness is a personality characteristic that explains why some individuals appear to flourish under stressful conditions whilst others become physically or psychologically unwell when facing identical circumstances. Rather than merely surviving stressful situations, hardy individuals actually thrive when confronted with challenging life events.
Suzanne Kobasa (1979) first proposed hardiness as a set of characteristics that some people possess whilst others do not. According to her colleague Salvatore Maddi (1986), hardiness provides individuals with existential courage - the willpower and determination to persevere despite life's setbacks and uncertainties about what the future may hold.
The three Cs of hardiness
Early research identified three core dimensions of hardiness, collectively known as the Three Cs:
Commitment
Hardy individuals demonstrate deep involvement in their relationships, activities, and personal identity. They engage wholeheartedly with whatever life presents to them, maintaining an optimistic outlook that their experiences will prove valuable, even during stressful periods. Their fundamental attitude reflects the belief that "if something's worth doing, it's worth doing fully, even if it's stressful." Rather than withdrawing and becoming isolated when faced with difficulties, they remain actively engaged.
Challenge
Hardy people respond to change in a distinctive manner, displaying resilience and viewing change as an opportunity or challenge rather than as a threat. They recognise that whilst life can be unpredictable, this uncertainty can be exciting and stimulating. Stressful situations are perceived as chances to learn and grow, which ultimately proves more fulfilling than retreating into comfort and routine.
Control
Hardy individuals maintain a strong belief that they can influence events and outcomes rather than being passive victims of circumstance. Even when facing highly stressful situations, they actively strive to shape their environment rather than becoming powerless and passive observers of life unfolding around them.
The Three Cs Framework:
- Commitment - Full engagement with life activities and relationships
- Challenge - Viewing stressful situations as opportunities for growth
- Control - Belief in personal ability to influence outcomes
Key research studies
Kobasa (1979) - Stress and illness in managers
Research Study: Kobasa (1979) - Hardiness in Managers
Participants: 670 male American middle and senior managers aged between 40 and 49 years
Aim: To identify factors that distinguish managers who remain healthy under stress from those who become ill
Procedure: Kobasa used the Schedule of Recent Experiences (SRRS) to identify participants who had experienced high levels of stress over the previous three years. She then examined their absenteeism records and illness levels using the Seriousness of Illness Survey to identify variations in stress responses.
Findings: The managers did not all respond to equivalent degrees of stress in the same manner. Some appeared more resilient, tolerating high stress levels without becoming ill or requiring time off work. When assessed, this resilient subset scored highly on measures of the Three Cs of challenge, commitment and control.
Evaluation:
- Strengths: Provided initial evidence for the hardiness concept; used real-world stressful situations; established the Three Cs framework
- Weaknesses: Limited to male managers only; correlational design prevents causal conclusions; relied on self-report measures
Maddi (1987) - Bell Telephone company reorganisation
Research Study: Maddi (1987) - Corporate Reorganisation Stress
Participants: 400 managers and supervisors at Bell Telephone company in the US
Aim: To examine responses to major organisational change and stress
Procedure: Maddi studied employees over several years during one of the largest corporate reorganisations in American history. Thousands of employees lost their jobs, creating an extremely stressful experience for remaining staff.
Findings: Approximately two-thirds of study participants showed adverse declines in performance and health, with outcomes including heart attacks, strokes, depression and drug abuse. However, the remaining third were not adversely affected. Instead, they flourished: their health did not deteriorate, they felt happier and more fulfilled at work than previously, and seemed rejuvenated by the stressful experience. These resilient managers scored highly on measures of the Three Cs and essentially welcomed the reorganisation as a challenge they could control whilst throwing themselves into making it work effectively.
Evaluation:
- Strengths: Longitudinal design; real-world naturalistic stressor; clear differentiation between hardy and non-hardy responses
- Weaknesses: Cannot establish causality; potential confounding variables; limited generalisability beyond corporate settings
Evaluation of hardiness
Measurement problems
Critical Issue: Validity of Hardiness Measures
Considerable controversy exists regarding how hardiness should be measured. Steven Funk (1992) highlighted that popular scales often measure hardiness by asking questions about negative traits such as powerlessness and alienation. Hardy individuals receive low scores on these items, so an absence of these negative traits is interpreted as indicating hardiness. However, these scales may actually be measuring a lack of neuroticism rather than hardiness itself, since neuroticism is characterised by anxiety, fear, moodiness and worry.
This means that substantial research exploring relationships between hardiness, stress and illness may be based on measures lacking validity. However, more recent scales such as the Dispositional Resilience Scale (Bartone, 2000) have been developed to avoid confounding hardiness with neuroticism, providing more valid measurement.
Roles of all three Cs
Serious questions have been raised about the relative contributions of the Three Cs to hardiness. It remains unclear how truly independent they are and whether they overlap substantially. For instance, there appears to be an element of control at the heart of both commitment and challenge. Additionally, extensive psychological research demonstrates the importance of personal control for wellbeing across various contexts. Therefore, control may be the overwhelmingly important factor determining hardy responses to stressors.
Current research tends to examine the components of hardiness separately. Jay Hull et al. (1987) recommended that research should focus on control and commitment only, abandoning the challenge component altogether.
Indirect effects of hardiness
Debate continues about whether hardiness effects on health and illness are direct or indirect. Richard Contrada (1989) found that hardy people had lower blood pressure, but could not determine the underlying explanation. One possibility is that being hardy directly reduces the physiological effects of stressors on the body. Alternatively, hardy people might be better at engaging in healthy behaviours, such as regular exercise and not smoking, which indirectly reduces their illness risk. The evidence remains inconclusive on this issue. However, from a practical perspective, this distinction matters little. If research demonstrates that hardiness has beneficial effects on health, then hardy characteristics appear desirable and should be developed through training and education.
Supporting research
Contrada (1989) - Laboratory stress study
Research Study: Contrada (1989) - Physiological Responses to Stress
Participants: Male university students
Aim: To examine physiological responses to stress in hardy versus non-hardy individuals
Procedure: Participants completed a stressful laboratory task whilst their physiological responses were monitored
Findings: Students who scored highest on hardiness measures showed lower blood pressure levels in response to the stressor. Interestingly, the lowest blood pressure levels were found in students who were not only hardy but also had Type B personalities.
This study provides evidence for hardiness having a biological basis in physiological stress responses, suggesting that hardiness represents a genuine characteristic of people who can resist stress effectively.
Bartone et al. (2008) - US Army Special Forces selection
Research Study: Bartone et al. (2008) - Military Selection
Participants: Candidates applying for positions within the US Army Special Forces
Aim: To examine the relationship between hardiness and success in high-stress military roles
Procedure: Researchers measured hardiness in candidates undergoing the tough four-week Special Forces assessment course
Findings: Those who successfully passed the course were significantly hardier than those who did not
This research led to the US military now routinely assessing candidates for high levels of hardiness, with training programmes frequently used to increase hardiness levels further.
Real-world applications
The concept of hardiness has proven valuable in practical settings. Research by Bartone (1999) linking hardiness to resilience in combat stress situations has led elite US military units to routinely assess and train for hardiness. This demonstrates the concept's validity - real-world applications confirm its usefulness for understanding stress responses.
Knowledge of people's hardiness levels can be used to predict who will be able to resist stress and who will not, which proves immensely useful in certain situations. However, the hardiness concept does not depend entirely on practical applications for its validity. Pursuing scientific understanding of behaviour remains valuable in itself, regardless of whether it leads to immediate real-world applications.
Key Points to Remember:
-
Hardiness consists of three components - commitment (full engagement with life), challenge (viewing stress as opportunities), and control (belief in personal agency)
-
Kobasa (1979) found that managers who remained healthy under stress scored highly on all Three Cs, whilst Maddi (1987) showed that hardy managers thrived during major organisational change
-
Measurement issues exist - early scales may have measured lack of neuroticism rather than hardiness itself, though newer scales address this problem
-
Research support comes from both laboratory studies (Contrada, 1989) and real-world applications (US Army Special Forces selection)
-
Control may be the most important component of hardiness, with some researchers suggesting the challenge component should be abandoned altogether
