Happiness Based on Basic Psychological Needs with the Mediation of Adaptation

One of the most important periods affecting physical, mental and social growth and health is the adolescence period of every person, where personality formation and identification takes place in this sensitive period. The purpose of this study was to model happiness based on basic psychological needs with the mediation of adaptation in adolescents. The applied research method and the descriptive correlation method were based on the structural equation model. The statistical population consisted of all working female adolescents studying in the second year of high school, 352 of whom were selected using multi-stage cluster random sampling and were asked to answer the questionnaires of Oxford Happiness (2002), basic psychological needs of Desi et al (2001), and Sinha and Singh (1993) students' adaptability. Data analysis was done using a structural equation model. The findings showed that the adaptation variable has been able to play a mediating role in the relationship between basic psychological needs and happiness. It can be concluded that when motivations or internal rewards are stronger than external motivations, the implementation of psychological needs becomes easier and has a positive effect on adolescent adaptation; because adaptation is achieved through internal incentives and reinforcements, and in this way, by creating a positive inner feeling in adolescence, it leads to an increase in happiness in teenagers; therefore, by providing a healthy and dynamic environment that fits the individual and personality needs of every teenager, it is necessary to promise well-being and happiness in teenagers.
