Purpose: To propose a procedure for comparative analysis of correlation relationships structure between psychological scales in samples of different sizes. Material and methods: A procedure of comparative analysis of correlation relationships structure between psychological indicators in groups of different sizes based on the «zet» method of R. Fisher is proposed. To illustrate the method, data from psychodiagnostic surveys of the nuclear power plant (NPP) personnel who worked in normal conditions and the personnel of the Chernobyl NPP at four different stages of aftermath activities in 1986–1987 were used. All the subjects performed the Minnesota Multiphasic Personality Inventory (MMPI); the results of each of the groups were subjected to a correlation analysis using the Pearson method. The analysis took into account average (0.5 ≤ r < 0.7) and strong (r ≥ 0.7) correlations. Results: Using the example of a number of psychodiagnostic examinations of the Chernobyl NPP personnel at various stages of aftermath activities, it is shown that the structure of correlation relationships between the MMPI scales can reflect the peculiarities of mental adaptation of professional teams working in regular and extreme conditions. It was shown that in the aftermath process by March–April 1987, the number of medium and strong pairwise Pearson correlations between the clinical MMPI scales increased. This fact apparently indicates that during this period, the NPP personnel were characterized by the simultaneous activation of various mechanisms of intrapsychic adaptation. The core of the correlation pleiad consisted of scales 1, 2, 7, and 8. Such a multidirectional reaction to the aftermath stressors was accompanied by a statistically significant increase in almost all clinical scales (except scale 6) of the average MMPI profile in comparison with the control group. The absence of stable correlations of clinical scales with the F scale indicates that the marked increase in the MMPI profile was not associated with a tendency to aggravation. By the period of November–December 1987, the hypochondria scale occupied a leading place in the correlation pleiad of the MMPI indicators of the Chernobyl NPP personnel, the number of its significant connections with other clinical scales (2, 3, 7 and 8) reached four. Apparently, the mechanism of anxiety somatization at that time could be considered as a syndrome-forming factor and taken into account when planning rehabilitation and health measures. Conclusion: The use of the proposed method of the strength standardization of pairwise correlation relationships between the MMPI scales allowed us to legitimately compare these indicators in groups that differ significantly in number. The chosen representation form of correlations facilitates the analysis of their structure.

Ego deficit is a frequent theme in the clinical literature for both patients of anorexia nervosa and victims of incest, but no previous study has analyzed, compared or contrasted the dynamics of the two groups psychometrically. The present investigation utilized the Minnesota Multiphasic Personality Inventory (MMPI) to study the mean profiles of 30 hospitalized anorexic women, 30 female victims of father-daughter incest, and 30 female subjects in a matched contemporary control group. Remarkable similarities were noted between the anorexic and incest groups (and differences from the control group) in characterological elevations on five clinical scales and lower scores on Barron's ego strength ( Es) scale. The results are discussed in terms of ego deficits shared by the two groups in spite of their distinctly different developmental and behavioral histories.

Mmpi Profile

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.

Purpose: Identification of the psychological preconditions of the staff stability during work at facilities after radiation accidents. Material and methods: This paper includes the comparative analysis of findings of psychological examination of the personnel of the Chernobyl Nuclear Power Plant (NPP) over the aftermath period (July 1986 – April 1987) and those of the control group consisted of the workers of the Smolensk NPP (102 persons). The psychological examination was based on the Minnesota Multiphasic Personality Inventory (MMPI) and the Sixteen Personality Factor Questionnaire (16PF). To achieve the purpose of this study, additional information was collected concerning the time of dismissal of previously examined employees of the Chernobyl NPP. Two groups of the surveyed workers were selected on the basis of the obtained information: – individuals who continued to work at the Chernobyl NPP after the accident until 1995 (group 1) – 74 persons; – individuals who resigned voluntary from the plant within a year and a half following the accident (group 2) – 29 persons. Results: The results of the examination using MMPI and 16-PF revealed significant differences in the generalized psychological portraits of group 1, group 2 and the control group. Individuals of the group 2 were more different in psychological parameters from the control group than those of group 1. So, according to the MMPI data, significant differences were found on the L (Lie) scale and on seven clinical scales: scale 1 (Hypochondriasis), scale 2 (Depression), scale 3 (Hysteria), scale 4 (Psychopathic Deviate), scale 6 (Paranoia), scale 7 (Psychasthenia) and scale 8 (Schizophrenia). The values in the group 2 were significantly higher than in the control group for all listed above scales. In addition, the group 2 had lower levels of 16PF factors: the Q1 (Openness to Change/Radicalism) and the secondary F4 factor (Independence). Also, a large proportion of individuals with abnormally pronounced personality traits (more than 70 T-score) were obtained in this group according to the MMPI data (41.4 %). The most frequently anomalous peaks were met on the scales 2 (Depression) and 1 (Hypochondriasis). The anomalous peaks on the MMPI profiles in the group 2 have been detected more than three times often than in the group 1. In addition, the group 2 had lower levels of 16PF factors: C (Emotional Stability) and F (Liveliness) than these factors of the group 1. Comparison of the examination results of the group 1 and the control group revealed the similarity of their generalized psychological portraits. At the same time, the group 1 demonstrated much higher values (p < 0.05) on MMPI scales: 1 (Hypochondriasis) and 2 (Depression) in comparison with the control group, however, these values were a bit higher than the general population standards (50 T-scores). Conclusion: The group of employees who quitted the job shortly after the accident was characterized by a pronounced uniqueness according to indicators of psycho-diagnostic tests, in comparison both with the control group, and with those who remained working at the plant for a long time. Apparently, these differences confirm our assumption about the existence of psychological characteristics that can be considered as preconditions for workers to make the decision to leave or continue working at the enterprise under changed conditions. This demonstrates the importance of taking into account the psychological characteristics of workers and the need for psychological support for personnel working under the exposure of harmful and hazardous factors after major radiation accidents.

This was a case control study involving 46 patients suffering from Parkinson disease (PD); 13 with impulse control disorder (ICD) and 33 without ICD; and 56 controls. The personality traits in these groups were analyzed using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). 46 patients with PD and 56 control group subjects were included into study. ICD were identified in 13 patients from PD group. There were higher scores than pathological threshold (65) in four domains of MMPI-2 Clinical scales: D (Depression), Pt (Psychastenia), Sc (Schizophrenia) and SI (Social introversion) in PD patients with ICD; but there were not statistical difference in any of these scales in comparison with the group of PD patients without ICD. In the case of MMPI-2 Subscales and Content scales there were higher scores than pathological threshold in eight domains of MMPI-2: SOD (Social Discomfort), PD4 (Psychopatic deviate - social alienation), PA1 (Paranoia - persecutory ideas), SC1 (Schizophrenia), PA_O (Paranoia - subtle), MA_O (Hypomania - obvious), SI1 (Syness/Self-Consciousness), SI3 (Alienation self and others) and Ho (Hostility), but there were statistical differences only in one of these domains in comparison with the PD patients without ICD: SI3 (alienation self and others). There was earlier onset of the disease and higher dose of levodopa in PD patients with ICD than in PD patients without ICD.Supported by project IGA MZ ČR NS 10301-3/2009

The investigation of personality traits of patients suffering from migraine headache with the Minnesota Multiphasic Personality Inventory (MMPI) is an important line of research, and differentiating syndromes in treating this disease is one of the characteristics of Chinese Medicine (CM). This study presents the MMPI-(Chinese edition) responses of 80 Chinese subjects with migraine and 40 non-headache healthy control subjects. Among them, migraine fire syndrome (MF) group consisted of 45 subjects (10 men, 35 women); migraine Qi stasis syndrome (MQ) group, 35 subjects (8 men, 27 women). The healthy control group was divided into healthy Qi stasis syndrome (HQ) group, 9 subjects (2 men, 7 women); and healthy normal (HN) group, 31 subjects (7 men, 24 women) according to CM diagnostic criteria. Statistical analysis was performed by pairs among four groups. The results revealed that both MF and MQ groups' MMPI profiles were significantly higher than that of the Normal (HN) group, and formed a 1.2.3.7 type slope. Profile deviation in the MQ group was slight, but in the MF group was serious and accompanied by a significant rising scores in F, paranoia (6), schizophrenia (8) and social introversion (0) subtests; HQ group's MMPI profile had a similar deviation as in the MQ group. The results suggest that CM migraine syndromes have an exact expression on MMPI profile, and that MMPI as an effective diagnostic method could be applied for CM syndrome discrimination. The "deviation of migraineurs' personality" may not be a special characteristic held only by migraineurs. The existence of different syndromes in migraine is one of the reasons that different scholars have reported different results on migraine by means of MMPI.

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.

Functional cognitive disorder (FCD) is a relatively common cause of cognitive symptoms, characterised by inconsistency between symptoms and observed or self-reported cognitive functioning. We aimed to improve the clinical characterisation of FCD, in particular its differentiation from early neurodegeneration. Two patient cohorts were recruited from a UK-based tertiary cognitive clinic, diagnosed following clinical assessment, investigation and expert multidisciplinary team review: FCD, (n = 21), and neurodegenerative Mild Cognitive Impairment (nMCI, n = 17). We separately recruited a healthy control group (n = 25). All participants completed an assessment battery including: Hopkins Verbal Learning Test-Revised (HVLT-R), Trail Making Test Part B (TMT-B); Depression Anxiety and Stress Scale (DASS) and Minnesota Multiphasic Personality Inventory (MMPI-2RF). In comparison to healthy controls, the FCD and nMCI groups were equally impaired on trail making, immediate recall, and recognition tasks; had equally elevated mood symptoms; showed similar aberration on a range of personality measures; and had similar difficulties on inbuilt performance validity tests. However, participants with FCD performed significantly better than nMCI on HVLT-R delayed free recall and retention (regression coefficient −10.34, p = 0.01). Mood, personality and certain cognitive abilities were similarly altered across nMCI and FCD groups. However, those with FCD displayed spared delayed recall and retention, in comparison to impaired immediate recall and recognition. This pattern, which is distinct from that seen in prodromal neurodegeneration, is a marker of internal inconsistency. Differentiating FCD from nMCI is challenging, and the identification of positive neuropsychometric features of FCD is an important contribution to this emerging area of cognitive neurology.

Abstract Background: The post-mastectomy changes to the locomotor system are related to the scar and adhesion or to the lymphatic edema after amputation which, in turn, lead to local and global distraction of the work of the muscles. These changes lead to body statics disturbance that changes the projection of the center of gravity and worsens motor response due to changing of the muscle sensitivity. Objective: The aim of the study was to evaluate the static balance of women after undergoing mastectomy. Methods: The study included 150 women, including 75 who underwent mastectomy (mean age: 60±7.6) years, mean body mass index (BMI): 26 (±3.6) kg/m2) and 75 who were placed in the control group with matched age and BMI. The study was conducted using a tensometric platform. Results: Statistically significant differences were found for almost all parameters between the post-mastectomy group and group of healthy women, regarding center of foot pressure (COP) path length in the Y and X axes and the mean amplitude of COP. Conclusions: First, the findings revealed that balance in post-mastectomy women is significantly better than in the control group. Second, physiotherapeutic treatment of post-mastectomy women may have improved their posture stability compared with their peers.

Since recently almost all housing built in Korean have shared walls and floor, diverse problems are unavoidable including noise between floor arising from noise and vibration. Many efforts have been made by the Korean government, but the number of complaints related with the noise between floors has been gradually increasing. Therefore, through the field measurements by house type, the current state of noise was understood. To do this, the noise between floors was measured in an apartment household and a multiplex house to perform a comparative analysis. As the result, the differences in the noise between the two house types were clarified. The findings of this research are expected to contribute to reduction of the noise between floors in an apartment building in the future.
