  • Focus on key evaluation points

Presentation

Evaluation of sociocultural explanations of PTSD

Strengths

Explains differences in both prevalence rates and the manifestation of symptoms across cultures and gender.

Research takes a holistic approach to the individual and identifies risk factors - with an emphasis on prevention rather than treatment.

Studies typically have high ecological validity.

Several studies are prospective and longitudinal in nature. In addition, researchers often employ triangulation to increase credibility.

Limitations

Research is correlational in nature - so cause and effect relationships cannot be determined.

The theories are descriptive rather than explanatory in nature. They do not explain the cause of the disorder.

Research does not isolate individual variables that may lead to the disorder.

There is some disagreement about measuring different constructs such as stress or one's level of social support.

Cross-cultural research is problematic.  Etic approaches are criticized for being too ethnocentric. Emic approaches make a comparison of the disorders difficult.
