Background: Physical and mental changes in the elderly may lead to decrease their hope and happiness in life. Research has shown the effectiveness of logo therapy, but the question of the present study is whether logo therapy-based educational package can help improve these symptoms in the retired elderly teachers? Aims: The purpose of the present study was to determine the effectiveness of the logo therapy-based educational package on the hope and happiness of retired teachers. Method: The method of this study was a quasi-experimental design with pre-test and post-test with control group. The statistical sample of this study included 30 retired elderly teachers of Kerman, who were selected by convenience sampling method and were randomly assigned to two experimental (15 subjects) and control groups (15 people). Experimental group participants received 12 sessions, twice a week, of logo therapy training based on positive psychology books (Seligman et al., 2000), cognitive-behavioral techniques (Stallard, 2005; Translated by Alizadeh et al., 2010), and logo therapy (Frankl) (Translated by Milani, 2016). To collect data, Miller & Powers (1988) Hope Inventory and the Oxford Happiness Measurement Scale (1989) were used. The data were analyzed by covariance. Results: The findings showed that the logo therapy-based educational package was effective on the hope and happiness of retired teachers (P<0/001). Conclusions: Therefore, it can be said that holding educational courses based on the logo therapy can help improve hope and happiness of the elderly teachers.
