Results: The correlation coefficient (r) value between social support and optimism is 0.87 which indicates a strongpositive relationship between both variables. The P value is <0.01 which indicates a significant statistical relationship. Conclusion: It can be stated that level of perceived social support is associated with the level of optimism.
