MMPI-A profiles of adolescent boys with a history of firesetting

Firesetting in childhood and adolescence is associated with the more severe end of the conduct-disorder continuum and is considered to be prognostic of later pathology. The literature provides limited understanding of the pathology underlying firesetting in juveniles. This study compared the Minnesota Multiphasic Personality Assessment-Adolescent profiles of 28 psychiatric inpatient adolescent boys with a history of firesetting with the profiles of 96 psychiatric inpatient adolescent boys who do not have a history of firesetting. Using multivariate analyses, the firesetting group appeared more pathological than did the nonfiresetting group as reflected by significantly higher scores on three clinical scales: Psychasthenia (Pt), Schizophrenia (Sc), and Mania (Ma). The firesetting group also scored significantly higher than did the nonfiresetting group on eight of the content scales: Adolescent-Depression, Adolescent-Alienation, Adolescent-Bizarre Mentation, Adolescent-Anger, Adolescent-Conduct Problems, Adolescent-Family Problems, Adolescent-School Problems, and Adolescent-Negative Treatment Indicators. Taken together, these results suggest that the pathology associated with juvenile firesetting is more complex as well as more severe than that associated with nonfiresetting conduct disorder. The firesetting group's profiles suggest that their psychopathology is not merely a severe behavior disorder but rather is indicative of feelings of distress, alienation, depression, and thought disorder or poor reality testing. This degree of inner turmoil may be motivational impetus for the firesetting itself.
