Positive psychology does it help improve grades?
We are at this time of year in which our children have finished school or college and are on vacation until next year, but this period of vacation is not so good in all cases. If our children have left them unfinished, they will be focused during the summer studying to recover in September, but positive psychology can help to improve their grades?
Currently positive psychology is a branch of psychology increasingly used consisting improve the quality of life of patients.
The difference between positive psychology and clinical is that the latter is to help patients with some psychopathology, positive psychology while you're looking to make the patient well find himself and those around him, learning to use personal success tools so that they will lead to happiness.

It is shown that a worker who is happy with what he does has a greater efficiency and productivity in the work they perform.
A study by the University of Hittite in Turkey published in the Journal of Advanced Management Science attempts to answer the question we pose in the title. The research was conducted with 229 students aged between 15 and 35 years, of which 53.7% were men and 46.3% women remaining.
The study was based on a standardized population where it was made questionnaire, which was provided to all participants equally. In the Psychological Capital Scale (name of the questionnaire) four factors, resilience, hope, optimism and self-efficacy were evaluated. These factors analyzed by comparing the academic performance of each student.
The results found no differences between resilience and optimism deciding academic success were found. Instead, hope and self-efficacy showed significantly different results between successful and unsuccessful students.
Although the study reveals interesting data on positive psychology, I must say that could have been better raised using a control group. On the other hand, although the number of participants with a relatively high number, are of a very specific population, and it would be very interesting to see if other people the same results or otherwise obtained if these results vary, try to understand what the why they do.
