Purpose of this research is to determine the psychometric features, for high school students, of Meaning in Life Questionnaire (MLQ) Steger, Frazier, Oishi, & Kaler (2006) which has been adapted to Turkish culture on university students by Demirbaş (2010). To this end, MLQ has been applied to 350 high school students from two different high school types. Exploratory and confirmatory factor analyses have been made for the validity of the scale. Reliability of the scale has been calculated with Cronbach's Alpha coefficient, test-retest reliability coefficient and corrected item-total correlation. As a result of the analysis, it has been determined that two factor structure of MLQ has been affirmed in the same way on high school students as it has been on university students. These results show that MLQ high school students are valid and reliable instrument. Depending on the research results some suggestions have been made to researchers and in terms of guidance and psychological counseling services.
