Objective Improvement in appearance is an important motivation for orthodontic treatment; nevertheless, not all patients with malocclusion seek treatment; therefore, the aim of this study was to compare the psychological state of patients with moderate to severe malocclusion who seek orthodontic treatment with patients who suffer from similar malocclusion but do not seek treatment. Materials and Methods Minnesota multiphasic personality inventory-2 questionnaire which assesses psychological states of people were given to 100 subject with moderate to severe malocclusion who were undergoing orthodontic treatment and 100 subjects with similar malocclusion who did not request orthodontic treatment. All subjects had similar demographic variables. Clinical scales measured by the test included: Hypochondriasis, depression, hysteria, psychopathic deviate, paranoia, psychasthenia, schizophrenia, and hypomania. The questionnaire consisted of 71 questions, and the subjects had to mark “True” or “False” in response. The scores were transformed into T-scores by a trained psychologist. The results were evaluated by independent t-test. Results and Conclusion The results of the test showed that both treated and untreated subjects were in similar psychological state and were psychologically normal; therefore, it is likely that other factors affect patients’ willingness for seeking orthodontic treatment rather than their psychological state.

The present study investigated the relationship between offender type and personality in 21 juvenile males adjudicated for crimes of a sexual nature and 30 juvenile males adjudicated for nonsexual offenses including Possession of Narcotics, Burglary, Criminal Mischief, Assault, and other crimes involving property. Subjects who were aged 13 to 17 years (mean age 15) and committed to the State of Connecticut, Long Lane School, were administered the Minnesota Multiphasic Personality Inventory–Adolescent (MMPI–A). Scores on Psychopathic Deviate and Schizophrenia scales contributed most to the juveniles being classified as sex offenders, whereas scores on Hysteria and Psychasthenia contributed primarily to subjects being classified as nonsex offenders. A single discriminant function attained statistical significance, thereby correctly classifying 77% of the nonsex offenders and 71% of the sex offenders. Results indicate that sex offenders may be distinguished from nonsex offenders according to clinical scales of the MMPI–A.

In recent years, several studies have addressed the issue of positive self-presentation bias in assessing parents involved in postdivorce child custody litigations. The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is widely used in forensic assessments and is able to evaluate positive self-presentation through its Superlative Self-Presentation S scale. We investigated the existence of a gender effect on positive self-presentation bias in an Italian sample of parents involved in court evaluation. Participants were 391 divorced parents who completed the full 567-item Minnesota Multiphasic Personality Inventory-2 during child custody evaluations ordered by several Italian courts between 2006 and 2010. Our analysis considered the S scale along with the basic clinical scales. North-American studies had shown no gender differences in child custody litigations. Differently, our results showed a significantly higher tendency toward “faking-good” profiles on the MMPI-2 among Italian women as compared to men and as compared to the normative Italian female population. Cultural and social factors could account for these differences.

Whether indexes of consistent responding on the Minnesota Multiphasic Personality Inventory (MMPI) measured dissimulation versus random responding was evaluated with Veterans Administration Medical Center psychiatric patients who were applying for disability benefits. Elevations on the Test-Retest index and Carelessness scale did not correspond with motivation to dissimulate. Comparing profiles without elevated validity indexes and with Carelessness scales that were either elevated or not elevated, the clinical scales were uniformly higher for profiles with heightened Carelessness scales.

54 inmates were subdivided into four groups and classified according to their index offense. The groups included Rapists ( n = 14), Incest Offenders ( n = 9), Child Molesters ( n = 11), General Offenders ( n = 20). Nonoffenders ( n = 20) were included as a control group. Psychometric tests including the Test of Nonverbal Intelligence, the Defining Issues Test, Survey of Interpersonal Values, Porteus Maze, and Minnesota Multiphasic Personality Inventory were administered to all inmate and control groups. Analysis showed the rapists and child molesters scored higher on moral reasoning on the Defining Issues Test; also rapists' scores were more elevated on the Psychopathic Deviate and Paranoia scales of the Minnesota Multiphasic Personality Inventory than those of other offender and control groups. These results imply that rapists and child molesters have the ability to understand moral issues; however, given their personality orientation, they ignore these interpersonal social values.

The psychological characteristics of 36 adult hemophiliacs, mean age 29.1 years, were analyzed by means of the Minnesota Multiphasic Personality Inventory (MMPI).The MMPI profile patterns were compared between various groups of the hemophiliac sample. By the clinical criterion used in our clinic, the sample was divided into severe and mild-moderate groups. The mild-moderate group appeared to be mildly anxious-hysterical, frightened, and health preoccupied with a profile of '317-2 9 5684 0/. The severe group appeared to be more estranged and alienated than the mild-moderate group, and has a significantly higher psychopathic deviate scale (P<.01). The mean profile of the severe group was '458 23-9167 0/.The most striking differences were found in comparing subgroups of high (N=9) vs low bleeders (N=9) within the group of severe hemophiliacs with factor levels of 3% or less. The high bleeders (>243 units/lb/year, mean Factor VIII level 1.6%) were much more disturbed, had all mean clinical scales above 60 (8'25137496-0/) and significantly higher scores for Depression, Psychasthenia, and Schizophrenia (P <.05). The low bleeders (< 243 units/lb/year, mean Factor VIII level 1.8%) had no mean scale scores above 60 ('34519687 2/0).The results indicated a clear difference in the psychological adjustment of the high and low bleeders to their illness. The high bleeders had a marked increase in self negativity i.e. a sense of being defective, of hopelessness and of pessimism. Surprisingly, the low bleeders has adjusted auite well to their serious vulnerability.

Raw-score means of the Cook-Medley Hostility scale are smaller in the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) normative group than in the MMPI normative group, and T scores are larger. The results contrast with those for the clinical scales but are consistent with results for some other scales. Reasons for the different patterns of MMPI and MMPI-2 scores are discussed.
