A study was conducted to compare validity, clinical, content, and supplementary scale scores of Hispanic adolescents to normative data on the MMPI-A. Volunteers, 30 boys, 17 girls, were Hispanic adolescents, aged 14 to 18 years from school and after-school settings. Analysis indicated elevated T score means on F1 (66), F2 (68), F (68), L (61), Hs (61), D (63), Sc (62), A-hea (63), A-biz (63), A-lse (61), A-las (60), A-sch (61), and IMM (61) scales for boys. Scores for low aspirations, low self-esteem, immaturity, and school problems were all interrelated. For girls, scores on no scales were elevated, but on several scales mean T scores, Hs, Hy, Ma, Si, A-anx, A-obs, A-hea, A-ang, A-las, MAC-R, and ACK, were below average. This suggests the MMPI-A may underpathologize for girls. Consistent with previous findings, the boys scored higher on the Immaturity Scale than the girls. It was speculated that the boys' dislike for school and low aspirations were related to the lower education and employment of their fathers compared to those for the normative sample. The A-las, A-sch, and IMM scales may prove to be useful in identifying adolescent boys "at-risk" for dropping out of school, if replication with much larger samples confirms present findings.

This study was conducted to examine the concurrent validity of the MMPI-A (Minnesota Multiphasic Personality Inventory-Adolescent) in an adolescent offender setting. From a sample of 50 court-adjudicated youths participating in an outpatient counseling program, 42 valid MMPI-A profiles were obtained, 33 of which were accompanied by counselor ratings of behavior problems. The highest mean elevations on the MMPI-A were on scales MAC-R (MacAndrew Alcoholism Scale-Revised), A-Con (Adolescent Conduct Problems), A-Sch (Adolescent School Problems), Pd (Psychopathic Deviate), and IMM (Adolescent Immaturity). Counselor ratings of behavior problems correlated highly with scales ACK (Alcohol and Drug Acknowledgment Scale), A-Sch, A-Ang (Adolescent Anger Problems), Ma (Hypomania), and PRO (Alcohol/Drug Problem Proneness). This pattern of results supports the concurrent validity of the MMPI-A for use in this setting.

In this study, we examined the ability of the MMPI-A (Butcher et al., 1992) to detect substance abuse problems in a juvenile correctional setting. Specifically, we evaluated the Alcohol/Drug Problem Acknowledgment scale (ACK; Weed, Butcher, & Williams, 1994), the Alcohol/Drug Problem Proneness scale (PRO; Weed et al., 1994), and the MacAndrew Alcoholism Scale-Revised (MAC-R; Butcher et al., 1992) in the prediction of substance abuse. In addition, the incremental validity of ACK in comparison to PRO was evaluated, as was the incremental validity of PRO in comparison to ACK. The sample consisted of 123 boys and girls from ajuvenile correctional facility in Northeastern Ohio. Results indicate that ACK and PRO, but not MAC-R, were related to interviewer ratings of substance abuse. Results point to the superiority of ACK over PRO in substance abuse identification.

This study investigated the accuracy of various indices involving the MMPI-A scales, ACK, MAC-R, and PRO in diagnosing substance abuse in a sample of 79 psychiatric inpatients. In the full sample, 89.9% of the cases were accurately classified by at least one of the three scales. The overall accuracy of classification was similar among males, females, Caucasians, and African Americans, although there was a tendency for more false positive misclassifications among males. Profile code type moderated the accuracy of classification with greatest accuracy for code types including Scales 1, 2, 3, 5, or 0 and least accuracy for code types including Scales 4, 6, or 9. ACK, MAC-R, and PRO were better at screening out cases of substance abuse than in accurately identifying those adolescents who were using substances.

In this paper, several MAC scheduling methods applicable to an underwater environment are proposed. Besides, a new marine communication system model was proposed to improve the reliability of the proposed SBMAC method. The scheme minimizes transmission of control frames except for data transmission and various transmission methods and ACK methods can be used together. Simulation models are set indices and analysis of the underwater environment is established to conduct reliable simulations. Consequently, the performance improvement of the proposed method is verified with respect to delay time, data transmission rate, memory utilization, energy efficiency, etc.
