The purpose of this study is to assess qualitatively the structure of the positive attitude toward life in adolescence and to develop, based on the results, a scale that measures the positive attitude toward life. In Study 1, I conducted the open-ended format survey of 54 university students on the attitude toward life and classify the obtained data with the KJ method. As a result, it was made clear by the findings of previous works that the psychological structure model obtained in Study 1 was valid as a structure model on the positive psychology characteristic in adolescence. In Study 2, based on the results of Study 1, I made a 46-item scale on the positive attitude toward life, and applied it to 252 adolescents. The factor analysis with the promax rotation indicated 5 subscales, 25 items. The alpha coefficient ranged from .76 to .91, and the retest reliability after a two-week interval ranged from .82 to .94. Its construct validity was confirmed in the relationship with the fulfillment scale (Ohno, 1984) and SWLS (Kakuno, 1994).
