The investigation of personality using the Rorschach Method has been historically established, however, its proper use requires continuous study, especially in regard to reliability, validity and normative references. This study’s objective was to verify stability indicators of Rorschach (French Approach) through a reassessment (after 15 years) of non-patient adults previously addressed in the normative study by Pasian (1998). A total of 88 adults, aged between 34 and 69 years old, of both sexes, with different socio-economic and educational levels, were reassessed in 2013 in the state of São Paulo, Brazil. The responses were independently rated by different judges, with adequate precision. The average results obtained collected in 1998 and 2013 were analyzed to determine if these two sets of data were significantly different from each other (Student’s t test, p ≤ .05) and the following variables were compared: Productivity indices, Apprehension Modes/Location, Formal Quality, Determinants, Contents and Banality. The overall stability level in these variables is considerable (mean r = .28, ± SD = 0.21). We discuss the theoretical approach of the Rorschach method regarding structural aspects of personality and developmental issues in personality assessment.
