Hobfoll’s “Limits of Resilience” article in Social Science and Medicine, is a great study (if you ignore the complicated statistics) because they followed over 1000 Palestinians through the Intifada. Charting depression and PTSD symptom trajectories, they identified factors predicting resilience most important of which was social support and the amount of resources lost. From this they correctly conclude:
Loss of psychosocial and material resources was associated with the level of distress experienced by participants at each time period, suggesting that resource-based interventions could benefit people exposed to chronic trauma. Such intervention could focus on all levels of resources, including personal resources (e.g., self-efficacy, job skills), social resources (e.g., social support, family relationships), material resources (e.g., housing, transportation), and condition resources (e.g., job avail- ability, fair access to work, open borders) (Norris & Stevens, 2007). Although any meaningful intervention is complex, such a resource model leads to targeted goals that are potentially achievable.
