	Abstract. The article presents the results of the Polish adaptation of the Gerotranscendence Scale Type 1 (GST-1) and the reliability and validity of the scale. In Poland 481 (Female = 312, Male = 169) elderly adults (aged 60–85) responded to a questionnaire. An exploratory factor analysis of the Polish version of the GST-1 revealed the same two-factor structure including the Cosmic Transcendence and Ego Transcendence, which had been reported by Tornstam (1994). Reliability and construct validity of the Polish version of the GST-1 were confirmed. The reliability coefficients (Cronbach’s alpha) for these dimensions amounted to, respectively, .72 and .64. These findings provide support for the use of the Polish version of the GST-1 as a measure of lifespan development among the elderly people in Poland. The GST-1 proved to be applicable not only for the elderly adults in Denmark, Sweden, Holland or USA but also for elderly adults in Poland.
