Objective: To investigate the personality (psychological) characteristics of adolescents with
bipolar disorder, and to provide clues for clinical differential diagnosis and treatment. Methods: The
Minnesota Multiple Personality Inventory (MMPI) and the Cartel 16 Personality Factors Questionnaire
(16PF) were performed on adolescent patients with bipolar disorder during depressive episodes; The
original score of the questionnaire was compared with that of normal subjects. Results: (1) In male
subjects, the comparison between biphasic group and normal subjects except for personality alienation
(Mf), the differences between the scores of the three efficacy scales and other clinical scales were
statistically significant. Among female subjects, the differences between the biphasic group and normal
subjects, the three efficacy scales and all clinical scales including Mf scores were statistically significant.
(2) Men and women with bipolar affection are the same in that their stability, perseverance, and selfdiscipline
are worse than those of ordinary people. Both have high fantasy and high tension, while women
are also dependent on strongness, excitement and anxiety. Higher than ordinary people. (3) Correlation
analysis of each subscale of the two scales shows that the Pa and Pt two subscales have a significant
negative correlation with the F subscale, and the K (correction score) scale has a positive correlation
with the Q3 scale. Conclusion: The psychological characteristics of adolescents with bipolar disorder are
psychopathic. Therefore, it is of great significance to pay attention to the role of psychiatric symptoms in
the diagnosis of adolescents with bipolar disorder to improve the recognition rate of this disease in this
age group.
