Find a peer reviewed article which discusses the effects of optimism on physical and psychological health. (You may need to find two articles in order to cover both the physical and psychological areas)
Summarize the article (articles) and state your opinion on the validity of the study or studies.
The following response provides you with four options for appropriate peer reviewed articles, the details about how they were found, guidance about how to write a summary and evaluate the validity of the study or studies, and general advice about APA style. (I attached PDF files of the articles for your convenience.)
The following four articles were found via EBSCOhost (see http://www.ebscohost.com) by searching the PsycARTICLES and Academic Search Complete databases using "TI optimism and psychological and physical and health" with the results limited to peer reviewed and full text articles. All four articles address the effects of optimism on both physical and psychological health, so two separate articles will not be necessary.
