The Zulliger test, inspired by the Rorschach method, is widely used in Brazil to assess personality, cognition, and emotional aspects, particularly in contexts requiring quick evaluations. Recent adaptations, such as the R-Optimized administration based on the (Rorschach Performance Assessment System (R-PAS), aim to enhance its validity and psychometric properties. We examined whether controlling the number of responses (3-5 per card) in the Zulliger test leads to an increase in distorted form responses (FQ-). A total of 64 adults participated (Mage = 32.9 years, SD= 10.8; 57.8 % women), with analyses conducted using repeated-measures ANOVA and paired t-tests. The result (F(1, 63) = 3.60, p= .015, ηp²= .07) showed no clinically significant increase in FQ-, indicating that the R-Optimized administration does not pathologize results. These findings reinforce the effectiveness of controlling the number of responses, highlight the need for updated normative data, and support adopting R-Optimized instructions which strengthen the reliability of the Zulliger test in psychological assessments.
