Abstract
Background. The results of scientific research conducted within the framework of the doctoral thesis "Forensic psychiatric evaluation of persons who have committed sexual criminal offenses".
Purpose. The research aimed to develop criteria for a forensic psychiatric assessment of individuals (suspects, accused persons), who have committed sexual assault, with the selection of the group with "limited sanity". It was based on the study of clinical and pathopsychological, socio-demographic patterns of mental disorders, using the method of situational analysis.
Materials. For this study the author analyzed 286 cases of forensic psychiatric examinations regarding the subject, those committed the sexual offense and were at the forensic psychiatric examination in Kyiv city center forensic psychiatric examination from 2000 to 2016 (16 years).
Objective. To determine the relationship between the degree of opportunities, to realize their actions and manage the solutions and expert author on the group - "responsibility" - was empirically selected group - "limited responsibility", which was formed artificially, based on the national concept of "limited responsibility".
Results. To determine the connection between the degree of the ability to realize one’s actions and to govern them and the decision of expert questions, all the observations were divided into two comparison groups. Diagnostics of paraphilia, determination of its forms and types were carried out according to the criteria for the diagnostics used in ICD-10, as well as definitions adopted in Ukrainian psychiatry. Sexual deviation and various forms of unusual sexual interests from generally accepted as part of the ethnic-cultural forms of sexual behavior.
Conclusions. Results revealed that the identified socio-demographic and clinical data in this scientific research can be determined by the criteria "limited responsibility" in forensic psychiatric examinations of persons who have committed sexual offenses. Consequently, these groups are heterogeneous whether examinee was intoxicated during the SDA or not the "limited sanity" of sexual assault is warranted.
Background
Among serious offense against the person, a special place is occupied by crimes against sexual integrity. A characteristic feature of this type of crime is that its most dangerous manifestation is violent crime (rape, violent gratification of sexual passion in an unnatural way). It is these crimes that are often associated with other forms of criminal violence - murders, bodily harm of varying severity, beatings, torture, etc. In addition to physical injuries, victims are suffering from psychological injuries too, which can destroy the whole future life of a person [1].
The fight against criminality and, in particular, sexual assault, is one of the most important areas of ensuring the national security of Ukraine. The right to sexual freedom, the right to sexual inviolability, the right to inviolability of sexual life are derived from personal human rights, namely the right to freedom and personal inviolability, privacy [2]. The social danger of this type of offense is determined by a number of unfavorable trends in its structure and dynamics, which determines the high importance of the problem of forensic psychiatric assessment of persons who have committed violent acts against sexual inviolability and sexual freedom of an individual. In the structure of sexual violence, there is an increase in aggression, cruelty of criminals, an increase in the number of violent rape, and serial sexual aggression [3].
Until recently, no clear criteria have been developed for forensic psychiatric assessment in individuals who have committed sexual assault, in particular, the criteria of “limited sanity”. Based on this comprehensive study of individuals, united by a common feature – the presence of the element of aggression in the structure of sexual assault it is relevant and timely to identify clear criteria for the assessment of the mental condition of these people.
Purpose of the study
The aim of the research was to develop criteria for a forensic psychiatric assessment of individuals (suspects, accused persons), who have committed sexual assault, with the selection of the group with "limited sanity". It was based on the study of clinical and pathopsychological, socio-demographic patterns of mental disorders, using the method of situational analysis.
Research methods
To achieve the purpose of the study, the following methods were used: information-analytical, clinical-psychopathological, socio-demographic, experimental-psychological, situational, expert, and statistical analysis methods.
Subject of the study
The subjects of the research were mental and behavioral disorders in individuals that committed a sexual assault.
Methods and materials
The study is based on the analysis of continuous sampling of individuals that committed a sexual assault who were undergoing forensic psychiatric examination in the Kyiv City Center of Forensic psychiatric expertise from 2000 to 2015 year, a total of 287 examinees were under expertise.
Information was collected by copying data from various official documents: medical records of an inpatient, criminal case materials, acts of forensic psychiatric assessment (FPA) into a specially designed examination card, which contains general information about the subject and expertise, anamnestic, socio-demographic, clinical and individually psychological characteristics of the subject, data on the identity of the victim, the crime and the post-criminal situation, the behavior of the examinee during the period of the FPA.
Results and discussion
In order to determine the connection between the degree of the ability to realize one’s actions and to govern them and the decision of expert questions, all the observations were divided into two comparison groups: Group 1 – 200 observations: the subjects, recognized as "sane", Group 2 – 14 observations: the subjects that are recognized as “insane”; Group 3 – of “limited sanity” - 73 observations. This group mainly (71 observations) was formed artificially with the first group - “sane”, based on the concept of “limited sanity”.
The concept of limited sanity is based on a systematic approach, which was developed in the Ukrainian forensic psychiatry by V. B. Pervomajskyj and the methodological position of F. V. Kondratiev’s "personality-activity " [4], [5].
Diagnostics of paraphilia, determination of its forms and types were carried out according to the criteria for the diagnostics used in ICD-10, as well as definitions adopted in Ukrainian psychiatry. Sexual deviation and various forms of unusual sexual interests from generally accepted as part of the ethnic-cultural forms of sexual behavior [6], [7].
To evaluate the correlation between nominal variables, for example, gender and seriality, or “group of sanity” and “personality type”, the Cramer's V and phi indicators are widely used [8]. The latter coefficient, in turn, is used for no more than 2 categories in a variable (for example, gender - “man” or “husband” and seriality - whether or not (2x2). Cramer's V can be used for any number of categories. the number of categories is presented in Table 1.
The number of categories (DF = (number of rows - 1) * (number of columns -1) | Weak correlation | Average correlation | Strong correlation |
---|---|---|---|
1 | 0.10 | 0.30 | 0.50 |
2 | 0.07 | 0.21 | 0.35 |
3 | 0.06 | 0.17 | 0.29 |
4 | 0.05 | 0.15 | 0.25 |
5 | 0.05 | 0.13 | 0.22 |
Cohen's w | 0.10 | 0.30 | 0.50 |
The problem with Cramer's V is that for large DF values, there are no generally accepted reference values. That is why Cramer's V will be further listed in Cohen's W according to the formula w = V √ a - 1, where “a” is the number of columns minus one. Since the groups below are represented as columns (3-1 = 2), that is, it can be simplified up to V * 1.4142. In this case, the number of columns should not exceed the number of rows. In the latter case, standard Cramar's V will be used.
The hypothesis of the study, in this case, is that if there really is a need to create a new category for “limited sanity”, then we will see a correlation for many indicators, that is, certain properties of the subjects will, in fact, be inherent only to this group.

Pairwise comparison of groups. Relative risk.
For further analysis, a pairwise comparison of the groups was carried out, namely, “limited sanity” with the insane and “limited sanity” with the sane. The hypothesis is that an artificially created group of "limited sanity" has different indicators with other groups. For this, we used the method of assessing relative risk, which is used for two dichotomous variables (2 nominal variables, which have only 2 categories).
Relative risk in the “limited sanity” group compared to the “sanity” group
Indicator | Value |
---|---|
Relative risk | 0.50; 95% CI 0.19-0.127 |
Pearson Chi-square | 61.315 |
Credibility | P<0.001 |
“Limited sanity” group 50% more often had clichéd SDA than a group of “sane”; statistically significant.
Indicator | Value |
---|---|
Relative risk | 0.214 (0.115-0.399) |
Pearson chi-square | 25.891 |
Credibility | <0.001 |
“Limited sanity” group almost 5 times more likely to commit serial offenses.
Indicator | Value |
---|---|
Relative risk | 4.841 (1.115-21.024) |
Pearson chi-square | 5.322 |
Credibility | 0.021 |
“Limited sanity” group almost 5 times more likely to commit a crime on their own, without a group; statistically significant.
Indicator | Value |
---|---|
Relative risk | 0.282 (0.162-0.493) |
Pearson chi-square | 20.784 |
Credibility | <0.001 |
“Limited sanity” group almost 4 times less likely to have committed the SDA while intoxicated.
Conclusion
Calculation of the correlation strength by indicators showed that after the introduction of an empirically distinguished group of individuals with “limited sanity”, there is a correlation (medium and strong) between the group of “sanity” and the presence of alcohol intoxication, the nature of the SDA, the diagnosis during examination, the motivation of the SDA, the type of emotion that dominates the person, the type of SDA, “clichéness” and seriality. “Limited sanity” from “sane” reliably and significantly differ in such dichotic indicators as “clicheness”, seriality, whether the SDA was committed independently or as part of a group, and whether examinee was intoxicated during the SDA or not. Consequently, these groups really are heterogeneous and the highlighting of the "limited sanity" of sexual assault is warranted.
