Provided is a system for early screening of children at risk of developing a mental illness in the future. This early screening system for children's mental illness risk is characterized by being provided with: an information acceptance unit for accepting sex information and eight T scores for Withdrawn (Ti), Somatic Complaints (Tii), Anxious/Depressed (Tiii), Social Problems (Tiv), Thought Problems (Tv), Attention Problems (Tvi), Delinquent Behavior (Tvii), and Aggressive Behavior (Tviii) as determined using the CBCL (4-18) or eight T scores for Anxious/Depressed (Ti), Withdrawn/Depressed (Tii), Somatic Complaints (Tiii), Social Problems (Tiv), Thought Problems (Tv), Attention Problems (Tvi), Rule-breaking Behavior (Tvii), and Aggressive Behavior (Tviii) as determined using the CBCL (6-18); and a calculation unit which calculates a z value by substituting the sex information and the eight T scores in equation 1 below (if the eight T scores are determined using the CBCL [4-18]) or in equation 2 below (if the eight T scores are determined using the CBCL [6-18]), and calculates a possibility p of developing a mental illness in the future on the basis of the z value and equation 3 below. [equation 1] z= -6.593 + 0.121 × Ti - 0.063 × Tii + 0.333 × Tiii + 0.045 × Tiv + 0.286 × Tv + 0.122 × Tvi - 0.011 × Tii - 0.448 × Tviii + 0.446 × sex (female = 1, male = 0) [equation 2] z = - 6.593 + 0.121 × Tii - 0.063 × Tiii + 0.333 × Ti + 0.045 × Tiv + 0.286 × Tv + 0.122 × Tvi - 0.011 × Tvii - 0.448 × Tiii + 0.446 × sex (female = 1, male = 0)
