People tend to be with others by nature. In this way, it meets the need to care for others and to be cared for by others. Besides, one wants to be lonely in a way with the tendency to keep the painful thoughts and feelings that he owns about himself and which he does not want to share with others. In order to lead a happy and healthy life, it is necessary to be in contact with both others and their own. In this sense, the direction of man's self-assessment determines his well-being. Social support from important people in his life is vital rather than introverted for subjective well-being. Subjective well-being can be expressed as the existence of positive emotions and the absence of negative emotions based on the subjective and emotional evaluation of the individual's life subjectively. From this point of view, it includes all the evaluations of one's own life. Here, it is possible to talk about both positive and negative emotions. In every period of life, the individual needs social support from his/her environment in order to be able to adapt to different living conditions. In addition, getting rid of the stressors of life and providing the happiness and satisfaction of life can be achieved by getting sufficient social support. Accordingly, one of the most important factors in getting rid of negative emotions is to feel the existence of strong social environment. The subjective well-being of individuals can be mentioned when social support is adequately met. Every individual needs to be qualified to express himself/herself or to understand others. Self-disclosure, which is the most important factor in self-expression, is one of the most important parts of communication. Self-storage, which is defined as refusal to share negative affect with others, has an impact on the social world of the individual and may cause the individual to use his/her social networks inadequately or not at all. Briefly, human beings seek an environment in which they can open themselves against the problems they face. Because the social environment that the individual has has a positive effect on his problems, affects his mood positively and makes him feel happy and comfortable. The fact that the individual can express his/her ideas towards the social environment he/she has contributed to the well-being of the individual while strengthening the communication. However, it can be expressed as an individual hiding himself, not opening himself up to others. Individuals who open themselves at a low level actually hide themselves. This situation negatively affects the well-being of the individual. Recent studies show that the individual feels relieved when he/she receives the social support he/she expects and can share his/her problems. The purpose of this study is to examine the levels of subjective well-being, perceived social support and self-preservation of prospective teachers in the name of economic situation, psychological support, and place of residence in the educational process, mother education, father education and special relations. The sample of the research is composed of 488 (288 female, 200 male) prospective teachers studying at the Faculty of Education of a university in the Turkish Republic of Northern Cyprus. The 'Subjective Well-Being Scale' developed by Dost (2004) was used to measure the subjective well-being of the participants. In order to measure the perceived social support perception, 'Multidimensional Perceived Social Support Scale' was used which was adapted to Turkish by Eker and Akar (1995). The self-preservation scale, developed by Larson and Chastain (1990) and adapted to Turkish by Terzi, Güngör and Erdayı (2010), has been used to determine self-preservation levels. The study was in descriptive model and the screening method was used. In order to determine whether there is any difference between the groups in the analysis of data, independent group’s t-test for binary variables and one-way variance analysis for more than two variables were applied. Pearson Correlation technique was used for correlation analysis. When the results of the research were examined, it was seen that the perceived social support and self-retention levels of teacher candidates differed according to gender, relationship and education level of parents. However, there were no significant differences in the subjective well-being of teacher candidates in terms of variables. According to these data, female teacher candidates perceived more social support from their families, friends and special people. It can be said that prospective teachers who has relationship have more support from their families and private people in their life. In addition, it can be said that the higher the educational level of the parents, the higher the perceived social support of the candidate teachers. Looking at the self-retention levels, it can be stated that male teacher candidates, pre-service teachers who have no special relationship in their lives, a
