Study on twins suggests most people return to their normal happiness level after trauma

Scientists have yet to pin down an all-inclusive measurement for this quality.“No consensus exists in social science…about the best and most complete definition of well-being,” Misheva remarked.Nevertheless, the data show that the adaptation theory holds up, at least in this case.Future studies may include better measures for well-being and more specific information about traumatic experiences in order to formulate a better plan for helping victims.“Victims of different traumatic experiences should be assisted in order to recover more quickly from their ordeals,” said Misheva. “All of these policies could contribute to a happier society.” Can people really adapt to intense experiences and return to the way they were?  Or do those experiences permanently affect their well-being?This is the question scientists sought to answer in a 2015 study published in the Journal of Happiness Studies.The researchers used a twin study to analyze the emotional well-being of participants after major life stressors.  Emotional well-being is “the emotional quality of everyday experiences, the positive and negative affect that makes one’s life pleasant or unpleasant,” according to Violeta Misheva, corresponding author.last_img
