Post-traumatic growth


Post-traumatic growth or benefit finding is positive psychological change experienced as a result of adversity and other challenges in order to rise to a higher level of functioning. These circumstances represent significant challenges to the adaptive resources of the individual, and pose significant challenges to their way of understanding the world and their place in it. Post-traumatic growth involves "life-changing" psychological shifts in thinking and relating to the world, that contribute to a personal process of change, that is deeply meaningful.

History

The general understanding that suffering and distress can potentially yield positive change is thousands of years old. For example, some of the early ideas and writing of the ancient Hebrews, Greeks, and early Christians, as well as some of the teachings of Hinduism, Buddhism, Islam and the Baha'i Faith contain elements of the potentially transformative power of suffering. Attempts to understand and discover the meaning of human suffering represent a central theme of much philosophical inquiry and appear in the works of novelists, dramatists and poets.
Traditional psychology's equivalent to thriving is resilience, which is reaching the previous level of functioning before a trauma, stressor, or challenge. The difference between resilience and thriving is the recovery point – thriving goes above and beyond resilience, and involves finding benefits within challenges.
The term "post-traumatic growth" was coined by psychologists at the University of North Carolina at Charlotte. According to Tedeschi, as many as 89% of survivors report at least one aspect of post-traumatic growth, such as a renewed appreciation for life.
Variants of the idea have included Crystal Park's proposed stress related growth model, which highlighted the derived sense of meaning in the context of adjusting to challenging and stressful situations, and Joseph and Linley's proposed adversarial growth model, which linked growth with psychological wellbeing. According to the adversarial growth model, whenever an individual is experiencing a challenging situation, they can either integrate the traumatic experience into their current belief system and worldviews or they can modify their beliefs based on their current experiences. If the individual positively accommodates the trauma-related information and assimilates prior beliefs, psychological growth can occur following adversity.

Causes

Post-traumatic growth occurs with the attempts to adapt to highly negative sets of circumstances that can engender high levels of psychological distress such as major life crises, which typically engender unpleasant psychological reactions. Growth does not occur as a direct result of trauma; rather, it is the individual's struggle with the new reality in the aftermath of trauma that is crucial in determining the extent to which post-traumatic growth occurs. Encouragingly, reports of growth experiences in the aftermath of traumatic events far outnumber reports of psychiatric disorders, since continuing personal distress and growth often coexist.
As far as predictors of post-traumatic growth, a number of factors have been associated with adaptive growth following exposure to a trauma. Spirituality has been shown to highly correlate with post-traumatic growth and in fact, many of the most deeply spiritual beliefs are a result of trauma exposure. Social support has been well documented as a buffer to mental illness and stress response. In regards to post-traumatic growth, not only are high levels of pre-exposure social support associated with growth, but there is some neurobiological evidence to support the idea that support will modulate a pathological response to stress in the hypothalamic-pituitary-adrenocortical pathway in the brain. As Richard G. Tedeschi and other post-traumatic growth researchers have found, the ability to accept situations that cannot be changed is crucial for adapting to traumatic life events. They call it "acceptance coping", and have determined that coming to terms with reality is a significant predictor of post-traumatic growth. It is also alleged, though currently under further investigation, that opportunity for emotional disclosure can lead to post-traumatic growth though did not significantly reduce post-traumatic stress symptomology. Gender roles did not reliably predict post-traumatic growth though are indicative of the type of trauma that an individual experiences. Women tend to experience victimization on a more individual and interpersonal level while men tend to experience more systemic and collective traumas. Given that group dynamics appear to play a predictive role in post-traumatic growth, it can be argued that the type of exposure may indirectly predict growth in men.

Post-traumatic growth and personality

Historically, personality traits have been depicted as being stable following the age of 30. Since 1994, research findings suggested that personality traits can change in response to life transition events during middle and late adulthood. Life transition events may be related to work, relationships, or health. Moderate amounts of stress were associated with improvements in the traits of mastery and toughness. Individuals experiencing moderate amounts of stress were found to be more confident about their abilities and had a better sense of control over their lives. Further, moderate amounts of stress were also associated with better resilience, which can be defined as successful recovery to baseline following stress. An individual who experienced moderate amounts of stressful events was more likely to develop coping skills, seek support from their environment, and experience more confidence in their ability to overcome adversity.

Post-traumatic growth

Post-traumatic growth refers to positive personality change following traumatic life events. Experiencing a traumatic event can have a transformational role in personality among certain individuals and facilitate growth. For example, individuals who have experienced trauma have been shown to exhibit greater optimism, positive affect, and satisfaction with social support, as well as increases in the number of social supportive resources. Similarly, research reveals personality changes among spouses of terminal cancer patients suggesting such traumatic life transitions facilitated increases in interpersonal orientation, prosocial behaviors, and dependability scores.
Importantly, experiencing a traumatic life event per se does not lead to post-traumatic growth. Not everyone who experiences a traumatic event will directly develop post-traumatic growth. Rather, an individual’s emotional response to the traumatic event is significant in determining the long-term outcome of that trauma. The outcome of traumatic events can be negatively impacted by factors occurring during and after the trauma, potentially increasing the risk of developing post-traumatic stress disorder, or other mental health difficulties.
Further, characteristics of the trauma and personality dynamics of the individual experiencing the trauma each independently contributed to post-traumatic growth. If the amounts of stress are too low or too overwhelming, a person cannot cope with the situation. Personality dynamics can either facilitate or impede post-traumatic growth, regardless of the impact of traumatic events.

Mixed findings

Research of post-traumatic growth is emerging in the field of personality psychology, with mixed findings. Several researchers examined post-traumatic growth and its associations with the big five personality model. Post-traumatic growth was found to be associated with greater agreeableness, openness, and extraversion. Agreeableness relates to interpersonal behaviors which include trust, altruism, compliance, honesty, and modesty. Individuals who are agreeable are more likely to seek support when needed and to receive it from others. Higher scores on the agreeableness trait can facilitate the development of post-traumatic growth.
Individuals who score high on openness scales are more likely to be curious, open to new experiences, and emotionally responsive to their surroundings.  It is hypothesized that following a traumatic event, individuals who score high on openness would more readily reconsider their beliefs and values that may have been altered. Openness to experiences is thus key for facilitating post-traumatic growth. Individuals who score high on extraversion were more likely to adopt more problem-solving strategies, cognitive restructuring, and seek more support from others. Individuals who score high on extraversion use coping strategies that enable post-traumatic growth. Research among veterans and among children of prisoners of war suggested that openness and extraversion contributed to post-traumatic growth.
Research among community samples suggested that openness, agreeableness, and conscientiousness contributed to post-traumatic growth. Individuals who score high on conscientiousness tend to be better at self-regulating their internal experience, have better impulse control, and are more likely to seek achievements across various domains. Conscientiousness trait has been associated with better problem-solving and cognitive restructuring. As such, individuals who are conscientious are more likely to better adjust to stressors and exhibit post-traumatic growth.
Other research among bereaved caregivers and among undergraduates indicated that post-traumatic growth was associated with extraversion, agreeableness, and conscientiousness. As such, the findings linking the big five personality traits with post-traumatic growth are mixed.

Trauma types, personality dynamics, and post-traumatic growth

Recent research is examining the influence of trauma types and personality dynamics on post-traumatic growth. Individuals who aspire to standards and orderliness are more likely to develop post-traumatic growth and better overall mental health. It is hypothesized that such individuals can better process the meaning of hardships as they experience moderate amounts of stress. This tendency can facilitate positive personal growth. On the other hand, it was found that individuals who have trouble in regulating themselves are less likely to develop post-traumatic growth and more likely to develop trauma-spectrum disorders and mood disorders. This is in line with past research that suggested that individuals who scored higher on self-discrepancy were more likely to score higher on neuroticism and exhibit poor coping. Neuroticism relates to an individual’s tendency to respond with negative emotions to threat, frustration, or loss. As such, individuals with high neuroticism and self-discrepancy are less likely to develop post-traumatic growth.

Characteristics

Results seen in people that have experienced post-traumatic growth include some of the following: greater appreciation of life; changed sense of priorities; warmer, more intimate relationships; greater sense of personal strength; and recognition of new possibilities or paths for one's life and spiritual development. Two personality characteristics that may affect the likelihood that people can make positive use of the aftermath of traumatic events that befall them include extraversion and openness to experience. Also, optimists may be better able to focus attention and resources on the most important matters, and disengage from uncontrollable or unsolvable problems. The ability to grieve and gradually accept trauma could also increase the likelihood of growth. It also benefits a person to have supportive others that can aid in post-traumatic growth by providing a way to craft narratives about the changes that have occurred, and by offering perspectives that can be integrated into schema change. These relationships help develop narratives; these narratives of trauma and survival are always important in post-traumatic growth because the development of these narratives forces survivors to confront questions of meaning and how answers to those questions can be reconstructed. Individual differences in coping strategies set some people on a maladaptive spiral, whereas others proceed on an adaptive spiral. With this in mind, some early success in coping could be a precursor to post-traumatic growth. A person's level of confidence could also play a role in her or his ability to persist into growth or, out of lack of confidence, give up.
In 2011 Iversen and Christiansen & Elklit suggested that predictors of growth have different effects on PTG on micro-, meso-, and macro level, and a positive predictor of growth on one level can be a negative predictor of growth on another level. This might explain some of the inconsistent research results within the area.
Post-traumatic growth has been studied in children to a lesser extent. A review by Meyerson and colleagues found various relations between social and psychological factors and post-traumatic growth in children and adolescents, but concluded that fundamental questions about its value and function remain.

Theories and findings

Resilience

In general, research in psychology shows that people are resilient overall. For example, Southwick and Charney, in a study of 250 prisoners of war from Vietnam, showed that participants developed much lower rates of depression and PTSD symptoms than expected. Donald Meichenbaum estimated that 60% of North Americans will experience trauma in their lifetime, and of these while no one is unscathed, some 70% show resilience and 30% show harmful effects. Similarly, 68 million women of the 150 million in America will be victimized over their lifetime, but only 10% will suffer insofar as they must seek help from mental health professionals.
In general, traditional psychology's approach to resiliency as exhibited in the studies above is a problem-oriented one, assuming that PTSD is the problem and that resiliency just means to avoid or fix that problem in order to maintain baseline well-being. This type of approach fails to acknowledge any growth that might occur beyond the previously set baseline, however. Positive psychology's idea of thriving attempts to reconcile that failure. A meta-analysis of studies done by Shakespeare-Finch in this area indicates that there is actually an association between PTSD symptoms and post-traumatic growth. The null hypothesis that there is no relationship between the two was rejected for the study. The correlation between the two was significant and was found to be dependent upon the nature of the event and the person's age. For example, survivors of sexual assault show less post-traumatic growth than survivors of natural disaster. Ultimately, however, the meta-analysis serves to show that PTSD and post-traumatic growth are not mutually exclusive ends of a recovery spectrum and that they may actually co-occur during a successful process to thriving.

Thriving

To understand the significance of thriving in the human experience, it is important to understand its role within the context of trauma and its separation from traditional psychology's idea of resilience. Implicit in the idea of thriving and resilience both is the presence of adversity. O'Leary and Ickovics created a four-part diagram of the spectrum of human response to adversity, the possibilities of which include: succumbing to adversity, surviving with diminished quality of life, resiliency, and thriving. Thriving includes not only resiliency, but an additional further improvement over the quality of life previous to the adverse event.
Thriving in positive psychology definitely aims to promote growth beyond survival, but it is important to note that some of the theories surrounding the causes and effects of it are more ambiguous. Literature by Carver indicates that the concept of thriving is a difficult one to define objectively. He makes the distinction between physical and psychological thriving, implying that while physical thriving has obvious measurable results, psychological thriving does not as much. This is the origin of much ambiguity surrounding the concept. Carver lists several self-reportable indicators of thriving: greater acceptance of self, change in philosophy, and a change in priorities. These are factors that generally lead a person to feel that they have grown, but obviously are difficult to measure quantitatively.
The dynamic systems approach to thriving attempts to resolve some of the ambiguity in the quantitative definition of thriving, citing thriving as an improvement in adaptability to future trauma based on their model of attractors and attractor basins. This approach suggests that reorganization of behaviors is required to make positive adaptive behavior a more significant attractor basin, which is an area the system shows a tendency toward.
In general, as pointed out by Carver, the idea of thriving seems to be one that is hard to remove from subjective experience. However, work done by Meichenbaum to create his Post-traumatic Growth Inventory helps to set forth a more measurable map of thriving. The five fields of post-traumatic growth that Meichenbaum outlined include: relating to others, new possibilities, personal strength, spiritual change, and appreciation for life. Though literature that addresses "thriving" specifically is sparse, there is much research in the five areas Meichenbaum cites as facilitating thriving, all of which supports the idea that growth after adversity is a viable and significant possibility for human well-being.

Aspects of post-traumatic growth

Another attempt at quantitatively charting the concept of thriving is via the Post-traumatic Growth Inventory. The inventory has 21 items and is designed to measure the extent to which one experiences personal growth after adversity. The inventory includes elements from five key areas: relating to others, new possibilities, personal strength, spiritual change, and appreciation for life. These five categories are reminiscent of the subjective experiences Carver struggled to quantify in his own literature on thriving, but are imposed onto scales to maintain measurability. When considering the idea of thriving from the five-point approach, it is easier to place more research from psychology within the context of thriving. Additionally, a short form version of the Post-traumatic Growth Inventory has been created with only 10 items, selecting two questions for each of the five subscales. Studies have been conducted to better understand the validity of this scale and some have found that self-reported measures of post-traumatic growth are unreliable. Frazier et al. reported that further improvement could be made to this inventory to better capture actual change.
One of the key facets of post-traumatic growth set forth by Meichenbaum is relating to others. Accordingly, much work has been done to indicate that social support resources are extremely important to the facilitation of thriving. House, Cohen, and their colleagues indicate that perception of adequate social support is associated with improved adaptive tendency. This idea of better adaptive tendency is central to thriving in that it results in an improved approach to future adversity. Similarly, Hazan and Shaver reason that social support provides a solid base of security for human endeavor. The idea of human endeavor here is echoed in another of Meichenbaum's facets of post-traumatic growth, new possibilities, the idea being that a person's confidence to "endeavor" in the face of novelty is a sign of thriving.
Concurrent with a third facet of Meichenbaum's post-traumatic growth, personal strength, a meta analysis of six qualitative studies done by Finfgeld focuses on courage as a path to thriving. Evidence from the analysis indicates that the ability to be courageous includes acceptance of reality, problem-solving, and determination. This not only directly supports the significance of personal strength in thriving, but can also be drawn to Meichenbaum's concept of "new possibilities" through the idea that determination and adaptive problem-solving aid in constructively confronting new possibilities. Besides this, it was found in Finfgeld's study that courage is promoted and sustained by intra- and interpersonal forces, further supporting Meichenbaum's concept of "relating to others" and its effect on thriving.
On Meichenbaum's idea of appreciation for life, research done by Tyson on a sample of people 2–5 years into grieving processing reveals the importance of creating meaning. The studies show that coping with bereavement optimally does not only involve just "getting over it and moving on", but should also include creating meaning to facilitate the best recovery. The study showed that stories and creative forms of expression increase growth following bereavement. This evidence is supported strongly by work done by Michael and Cooper focused on facets of bereavement that facilitate growth including "the age of the bereaved", "social support", "time since death", "religion", and "active cognitive coping strategies". The idea of coping strategies is echoed through the importance thriving places on improving adaptability. The significance of social support to growth found by Michael and Cooper clearly supports Meichenbaum's concept of "relating to others". Similarly, the significance of religion echoes Meichenbaum's "spiritual change" facet of post-traumatic growth.

Positive psychology

Post-traumatic growth can be seen as a form of positive psychology.

Criticisms and concerns

Concerns include that evidence of post-traumatic growth is very limited, and that it may be an illusion.
