Loss, Trauma, and Resilience:

From Heterogeneity to Flexibility

George A. Bonanno, Ph.D.

Bad things happen . . .

Page 3: Loss, Trauma, and Resilience - Rehpa loss, and trauma_by George Bonanno PAVI 25... · Driven by the poignancy and cost of these events, both clinical and scientific inquiry has focused

Frequency of stressors across 4 years of college - weekly on-line survey - 50 events from 4 categories

. . . frequently

Lalande & Bonanno (2011) Psychological Trauma

Page 4: Loss, Trauma, and Resilience - Rehpa loss, and trauma_by George Bonanno PAVI 25... · Driven by the poignancy and cost of these events, both clinical and scientific inquiry has focused

Driven by the poignancy and cost of these events, both clinical and scientific inquiry has focused primarily on psychological damage 1.Psychopathology 2.Average impact of the event itself

But . . . the picture is incomplete

Two Common Approaches

Bonanno (2004) American Psychologist; Bonanno, Westphal, & Mancini (2011) Annual Review Clinical Psychology

Page 5: Loss, Trauma, and Resilience - Rehpa loss, and trauma_by George Bonanno PAVI 25... · Driven by the poignancy and cost of these events, both clinical and scientific inquiry has focused

1. Focus on extreme: psychopathology • chronic grief and depression (10%-65%) • Posttraumatic Stress Disorder (PTSD) (5%-90%)

• Limitations – Emphasis on pathology can result in sampling bias

The limits of diagnoses and the problem of averages

1. Focus on extreme: psychopathology • chronic grief and depression (10%-65%) • Posttraumatic Stress Disorder (PTSD) (5%-90%)

• Limitations – Emphasis on pathology exacerbates sampling bias – Uninformative about the underlying distribution

1. Focus on extreme: psychopathology – chronic grief and depression (10%-65%) – Posttraumatic Stress Disorder (PTSD) (5%-90%)

2. Focus on average: impact of the event • Compare groups exposed vs. non-exposed • Compare across different types of events

• Averages are potentially misleading – often mistaken for mode – may be driven by extreme groups

• The problem with averages is that they . . . • “average out the interesting effects”

– (Bloembergen & Zewail, 1984, Journal of Physical Chemistry)

• “often do not describe reality at all” – (Banholzer, 2010, Research Technology Management)

• “are misleading” – (Parkinson, 1989, Climate Dynamics; B. F. Skinner, Journal of General

Psychology, 1936; Nissan & Shahmoon, 1993, Journal of Economics and Finance; Gaut et al., 2007, Nature Reviews, Genetics; Boyd, 1984 and Haigh, 1994; Mathematical Gazette; Day, 2008, Business Law Brief; Gregson et al, 1993, Biological Psychiatry . . . . . . . )

• can mask changes in the majority – (Casselli & Cunningham, 2009; Oxford Economic Papers)

• Averages are curious statistics that are meant to make

poor people happy. Averages tell us you will eat at least one chicken a year. But if you can’t afford a chicken, don’t worry; someone else will eat two

– paraphrased from La Statistica by Trilussa*

• "I really don't trust statistics much. A man with his head

in a hot oven and his feet in a freezer has statistically an average body temperature ”

– Charles Bukowski

* Paraphrased from archaic Italian by Antonio Malgaroli

Changing Lives of Older Couples (CLOC): A prospective study

• 1,532 married individuals from Detroit area • 205 lost a spouse during the 7-year course of

the study, – interviewed prior to bereavement (on average 3

years pre-loss), – Interviewed at least twice after bereavement (6 and

18 months post-loss).

Resilience and positive adjustment • Absence of symptoms and distress • Subjective well-being and life satisfaction • Level of mental health and functioning

– Less cortisol dysregulation (diurnal profile)(Ong et al., 2011)

• Positive adjustment as rated confidentially by close friends-relatives – Bereaved partners (Bonanno et al., 2005)

– High-exposure survivors of 9/11 (Bonanno et al., 2005).

• Positive emotion and experiences – Positive body image after cancer surgery (Lam et al., 2012)

Page 63: Loss, Trauma, and Resilience - Rehpa loss, and trauma_by George Bonanno PAVI 25... · Driven by the poignancy and cost of these events, both clinical and scientific inquiry has focused

Multiple, unique predictors with small effect sizes • Pre-event context

– Demographic factors (older, male, greater education) – Preparation and prior exposure – Economic resources (employment, income). – Beliefs (acceptance of death, justice, shared cultural norms) – Social resources (support, social network) – Personality (trait self-enhancement, optimism, hardiness, coping self-

efficacy, perceived control, etc). – Genetic disposition (G X E)

• Proximal exposure – Witnessing death, serious injury to others – Objective danger to self – Extent of loss (death, loss of property)

• The aftermath (distal exposure) – distal exposure (loss of economic, personal, or health resources) – Reduced search for meaning, worry, rumination – Reduced ongoing stress – Coping and appraisal – Positive emotion and regulatory flexibility

* Resources * – Conservation of Resources (COR) theory (Hobfoll,

1998, 2002)

– Resources help buffer the impact of adversity • Material: income, financial reserves • Work: employment, possibility of livelihood • Energy (health): absence of disease, health insurance,

availability of care • Interpersonal: Social support, affinity groups

Optimism

• Expectation of positive events in the future when there is no evidence to support those expectations (Scheier & Carver, 1985; Carver et al., 2010)

• Trait optimism: – General health and well-being: proactive health-

related coping (Carver et al., 2010, Clinical Psychology Review).

– Neural mechanism: imagining positive future events associated with amygdala and rostral anterior cingulate; greater in trait optimism (Sharot et al. 2007, Nature)

Regulatory Flexibility

• Theories of coping and emotion regulation emphasize their dynamic nature (Cole, Lazarus, Folkman, Gross et al…..)

– Person-situation interaction – “fit” with shifting nature of situational demands

• in practice, we tend toward static categorization of strategies as adaptive (e.g., reappraisal, finding meaning) or maladaptive (e.g., avoidance, suppression)

• “Fallacy of uniform efficacy” (Bonanno & Burton, 2013)

Emotion Context Sensitivity • Emotions are functional . . evolved as solutions to

specific threats and opportunities • The functions of emotions are “context bound” (Cole et al.,

1994)

• Match between contextual demands and specific functions of an emotion facilitates adaptation

sadness

match adaptive benefits

• Attention inward • Facilitates reframing • Evokes

sympathy/care from others
