Investigating the effectiveness of teaching positive thinking skills on the life expectancy and self-efficacy of second year high school students in Tabriz

The purpose of this research was to investigate the effectiveness of teaching positive thinking skills on the life expectancy and self-efficacy of second year high school students in Tabriz. This research was a semi-experimental type that was conducted in the form of a pre-test and a post-test with a control group. The research sample was selected by random cluster sampling of 40 people and then (20 people in the experimental group and 20 people in the control group) were randomly assigned to two experimental and control groups. The experimental group received eight sessions of forty-five minutes of positive thinking skills. All subjects were evaluated using Scherer's self-efficacy questionnaire and Snyder's life expectancy questionnaire. The results of the analysis of covariance showed that the teaching of positive thinking skills significantly increased self-efficacy and life expectancy in students. The results of this research showed that the method of teaching positive thinking skills can be used as an efficient method to increase students' self-efficacy and life expectancy.
