This study was conducted to test if Erikson’s psychosocial stages have predictive validity based on the self-reported concerns of the participants. There were 20 participants in the said study: ten males and ten females. The researcher asked and recorded the self-reported concerns of the participants. The researcher identified what particular psychosocial stage a participant was in. The percentage correct for the group was 90%. The percentage correct for each psychosocial stages were the following: stage 3 (Initiative vs. Guilt) -100%, stage 4 (Industry vs. Inferiority) -93.75%, stage 5 (Identity vs. Role Confusion)-93.75%, stage 6 (Intimacy vs. Isolation)-93.75%, stage 7 (Generativity vs. Stagnation)-93.75%, and stage 8 (Integrity vs. Despair)-100%. In favor of the male subjects, 87.5% were correct, while the percentage correct for female subjects was 92.5%. Based on the results, Erikson’s Theory on Psychosocial Stages may be true based on the self-reported concerns of the participants.
