Being raised in an environment where psychosocial stressors are more abundant, such as modern urban environments, puts individuals at greater risk: social factors. Families high in emotional expressiveness (ee) = overly critical and controlling, people with schizophrenia three-four times more likely to experience a relapse of their symptoms within a nine month period. Families low in ee = more supportive, accepting, and non-judging. More severe cases of schizophrenia are more difficult to manage, put more stress on the family, and end up causing greater emotional expression in their families.
