This study examines the Purpose in Life (PIL) questionnaire and attempts to find the most appropriate factor matrix structurewhen it is applied to a high school population. The goal of the study is to find a simple structure factor matrix with high reliabilityas measured by Cronbach’s alpha. Participants (N = 659) were randomly selected from all four grades of Washington Statemetropolitan area high schools. Findings indicate that while various multidimensional matrix structures exist for the instrumentwhen used with an adult population, when used with a high school population, there emerges a strong unidimensional factormatrix with a simple structure; it both fits the data well and results in very strong reliability (Cronbach’s α = .900). This analysissuggests that revising the PIL from 20 to 14 questions for high schoolers results in a unidimensional instrument, stronglysupported by all 14 questions and measuring with a very high reliability.
