The aim of the present study was to critically review theories and approaches related to positive thinking and to develop a theoretical model based on Islamic view, which is compatible with cultural values in Iran. To fulfill the stated aim, philosophical and historical foundations of positive thinking in different schools of thought including Leibnitz, Sadra, Kant, Freud and James were critically reviewed. In addition, the theoretical constructs associated with positive thinking including hope, positive automatic thoughts and paradigms of Seligman, Scheier and Carver in this regard were critically studied. Finally, based on the attachment theory of Bowlby, positive thinking was established on and its applications were explained for individuals' thinking styles about past events, present interpretations of events and future expectations. Since the attachment theory is a relational theory, positive thinking in this paradigm was discussed in a way that included individuals' relationship with transcendental being, others, nature, and the self.
