PMA is under the umbrella of positive psychology. In positive psychology, high self-efficacy can help in gaining success. PMA is considered a way of training yourself to be happy and reeping the benefits. Research has shown that through emotional intelligence training and positive psychology therapy, a person's attitudes and perceptions can be modified to improve one's personal and professional life.
Cancer specifically has received a lot of attention since survivors, have given their stories. Many studies have been done regarding PMA and its effects on peoples health, specifically with people with illnesses such as cancer and kidney disease. People with PMA have a significantly higher chance of survival and recovery. A study comparing people with chronic kidney disease with people without kidney disease showed that there was a significant difference between the groups. The kidney disease free group rated much higher in PMA.And females with chronic kidney disease were found to be significantly more superstitious. A study done with HIV-positive individuals found that a high health self-efficacy, a task-oriented coping style, and a positive mental attitude helped for a health-promoting lifestyle which has a significant effect on overall health.
Critics of PMA argue that it is not the secret to success but. The "self-help" industry has been criticized as a scam for authors to make money. There is little evidence, however, that self-help books, life coaching, and motivational speaking are harmful; a study of 100 psychotherapy patients found that of the 43 patients reading books 4 reported "mild harm or distress" while 34 reported "benefit without harm".
"Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it." is a quote by Eckhart Tolle.
