Comment: "Ok. de entrada te agradezco mucho. he aquì el contexto: "The 3-6/6-3 codetype was found among 0.6% of male and 1.4% of female adolescents receiving psychiatric services. Among adolescents, the most distinctive characteristic of this group was a relatively high incidence of suicide attempts, and one-third of adolescents in the Marks et al. (1974) study were seen for psychotherapy following such behaviors. In the Marks et al. 1970-1973 sample, this profile was associated with substance abuse, but not as extensively as other adolescent codetypes. In this sample, roughly 50% of these adolescents acknowledged drug involvement Interestingly, 40% of this 3-6/6-3 codetype group were academically superior students. Scale 4 (Pd: Psychopathic Deviate) Codetypes This MMPI-A scale consists of 49 items, with one item deleted from the original Pd scale due to inappropriate content Scale 4 was originally designed to identify or diagnose the psychopathic personality, now referred to under the DSM-III-R as antisocial personality disorder. As described by Dahlstrom, Welsh, and Dahlstrom (1972), the criterion group for scale 4 consisted largely of individuals who were court referred for psychiatric evaluation because of delinquent actions including lying, stealing, truancy, sexual promiscuity, alcohol abuse, and forgery The 49 items in the MMPI-A Pd scale cover a diverse array of content areas including family conflicts, problems with authority figures, social isolation, delinquency, and absence of satisfaction in everyday life Scale 4 has a substantial degree of item overlap with many of the validity and clinical scales, and it contains an almost equal number of true and false responses that are keyed in the critical direction."
