The population of this research has two sections; the first section includes the new related scientific documents from 10 to 20 texts that are collected by using targeted approach until achieving domination criteria. Inductive qualitative content analysis method was applied for analyzing the specialized texts that are related to the research. The second population contains the whole flight crew of Mahan Airline Company. The research sample is chosen by using targeted and snowball method and by 37 items has been reached to theoretical saturation.

The purpose of the present study is to investigate the training of self-encouragement based on Adler's theory of psychological capital and academic engagement of female high school students. This study was a semi-experimental research and used a pretest-posttest design with a control group. The sample consisted of 60 students (30 participants for experimental group and 30 participants control group) who were selected by multi-stage cluster sampling. The experimental group was then educated for self-encouragement for 8 sessions while the control group did not receive any training. The instrument used in this study was Schaufeli & Bakker's (2006) Academic Engagement Questionnaire and Luthan's (2007) Psychosocial Capital Questionnaire. Descriptive statistics were used to analyze data and Multivariate analysis of covariance was used to investigate the research hypotheses. By analyzing the data, results indicated that self-encouragement training increased the academic engagement and psychological capital of female students. Regarding the effectiveness of this training on increasing the academic engagement and psychological capital, this training is evaluated useful for students.
