Today, seeking has turned into to a challenging issue in philosophical texts, religious writings and speeches of psychologists. Books and magazine articles have recently discussed as the main outcome of study and practice in positive psychology. Of course, seeking is only one aspect of positive psychology. Due to this account, the main interests of positive psychology domain are and life satisfaction. (Schneider & Lopez, 2007)Martin Seligman as a well-known contemporary psychologist and as someone who's known as a pioneer and founder of positive psychology believes that psychology followed three main purposes before the Second World War: a) psychological disorder treatment, b) helping people enjoy a happy life, c) identifying and improving hidden powers of people (Seligman, 2002)This term happiness brings to mind several different concepts (e.g. happiness, satisfaction, joy, agreeableness, etc.). Thus, some so called mental improvement psychologists argue that it is an umbrella term including all the tests taken by a person about himself and his life. These tests consist of life satisfaction, excitement and positive temper, absence of depression and anxiety and its various dimensions are in form of understandings and sentiments. Therefore, if one claims life dissatisfaction, he or she enjoys little agreeable experiences and positive sentiments and has negative exciting emotions such as rage, anxiety and little mental prosperity. (Diner, 2003) Schwartz and Stark (2000) believe that happy people are those who are oriented toward optimisticism, in processing data, that is to say they process and interpret data in such a way that leads to happiness.Another definition regards as a relative issue and sensitive to the quality of one's life. For instance, someone might generally and constantly develop judgments on life satisfaction or points to some particular aspects of life such as entertainments (Abdolsallah, 2009). Personality is a concept which anyone knows but is not able to precisely define. The concept of personality is a prevailing and common concept and at the same time extremely complex concept in psychology. Its popular usage has declined to a desirable concept in other people's view while its scientific concepts are totally wrangled about. Any person is a combination of the three typical, cultural and individual characteristics and overall makes an extraordinary totality which is specifically considered in psychology of personality. As Parvin aigues, the range of definitions sways along the internal procedures of organism to apparent behavior of people interactions (Garoosi, 2001).Personality evaluation is also the most practical method in this field. Clinical psychologists attempt to study their patients or therapy seeking personalities in order to know their symptoms. They can only diagnose disorders and determine the best treatment process through personality evaluation using this method. Personality awareness is the fundamental part of most psychotherapies and pathology theories. Probably it is not exaggeration to say that without understanding this concept, psychotherapist methods and some psychological disorders cannot be clearly understood (Shoultz & Shoultz, 2006). Robert Me Crea and Paul Costa (1991) have presented the well-known five factor theory regarding personality and they attempt to prove the convergence of various approaches about this issue. The basis of factor analysis methods, according to Parvin, is characteristic which means one's general readiness to behave in a certain manner. Personality in this concept is a set of characteristics which determines a person.This form measures the main five factors of personality. These five factors include neuroticism (N), extroversion (E), openness (O), agreeableness (A) and conscientiousness(C). Each one of these factors consists of six characteristics. The five factor model has extensive uses in clinical issues and clinical specialist may use evaluation strategies of five factor model (Garoosi, 2001 ). …
