Human-Biomonitoring derived exposure and Daily Intakes of Bisphenol A and their associations with neurodevelopmental outcomes among children of the Polish Mother and Child Cohort Study.

BACKGROUND: Bisphenol A (BPA) is an industrial chemical mostly used in the manufacture of plastics, resins and thermal paper. Several studies have reported adverse health effects with BPA exposures, namely metabolic disorders and altered neurodevelopment in children, among others. The aim of this study was to explore BPA exposure, its socio-demographic and life-style related determinants, and its association with neurodevelopmental outcomes in early school age children from Poland. METHODS: A total of 250 urine samples of 7 year-old children from the Polish Mother and Child Cohort Study (REPRO_PL) were analyzed for BPA concentrations using high performance liquid chromatography with online sample clean-up coupled to tandem mass spectrometry (online-SPE-LC-MS/MS). Socio-demographic and lifestyle-related data was collected by questionnaires or additional biomarker measurements. Emotional and behavioral symptoms in children were assessed using mother-reported Strengths and Difficulties Questionnaire (SDQ). Cognitive and psychomotor development was evaluated by Polish adaptation of the Intelligence and Development Scales (IDS) performed by trained psychologists. RESULTS: Urinary BPA concentrations and back-calculated daily intakes (medians of 1.8 µg/l and 46.3 ng/kg bw/day, respectively) were similar to other European studies. Urinary cotinine levels and body mass index, together with maternal educational level and socio-economic status, were the main determinants of BPA levels in Polish children. After adjusting for confounding factors, BPA has been found to be positively associated with emotional symptoms (ß: 0.14, 95% CI: 0.022; 0.27). Cognitive and psychomotor development were not found to be related to BPA levels. CONCLUSIONS: This study represents the first report of BPA levels and their determinants in school age children in Poland. The exposure level was found to be related to child emotional condition, which can have long-term consequences including social functioning and scholastic achievements. Further monitoring of this population in terms of overall chemical exposure is required.

Predictors of illness acceptance in women with endometriosis.

BACKGROUND: The study aimed to identify significant predictors of illness acceptance in women with endometriosis. As potential predictive factors, variables related to the disease (pain frequency, co-morbid infertility, diagnostic delay, years of living with the diagnosis), demographic variables (age, place of residence, education, income, the fact of having children) and psychological variables (pain coping strategies) were taken into account. PARTICIPANTS AND PROCEDURE: The study participants - 247 women with endometriosis - were recruited in Poland in medical facilities from 6 large voivodship cities and through a patients' association. The participants filled in the following questionnaires: the Acceptance of Illness Scale (AIS), Endometriosis Health Profile-30 (EHP-30), and the Coping Strategies Questionnaire (CSQ). The data were analysed with the method of stepwise hierarchical regression. RESULTS: The final significant model explained 24% of the variance of the AIS score. The model consisted of the following variables: pain frequency, reinterpreting pain sensations, pain catastrophizing and praying/hoping. Only two variables were significant predictors in this model: pain frequency and pain catastrophizing. Years with diagnosis, age, diagnostic delay, place of residence, education, income, and the fact of having children were not significant. CONCLUSIONS: The interventions addressed to patients should support their acceptance of chronic pain and help them to develop adaptive pain coping strategies. Due to the co-morbidity of endometriosis-related pain and depression the inclusion of antidepressant pharmacotherapy and psychotherapy based on cognitive techniques is recommended.

Shame, guilt, time perspective, time of imprisonment and PTSD symptoms in sentenced motor vehicle accidents perpetrators - a preliminary report. / Wstyd, poczucie winy, perspektywa czasowa, czas odbywania kary pozbawienia wolnosci i objawy PTSD u skazanych sprawców wypadków drogowych ­ doniesienie wstepne.

OBJECTIVES: The study aimed at exploration of a relationship between PTSD symptoms, traumarelated guilt (TRG), time perspective (TP), and guilt/shame proneness among perpetrators of motor vehicle accidents (MVA). We also analyzed relationships between length of imprisonment, PTSD and trauma-related guilt. METHODS: The sample consisted of 37 incarcerated perpetrators of MVA. They were asked to fill in the set of questionnaires: Zimbardo Time Perspective Inventory, Guilt and Shame Proneness Inventory, Trauma-Related Guilt Inventory). RESULTS: The results showed that 50% of the perpetrators met the DSM-5 PTSD criteria. The proneness to guilt and shame positively correlated with the trauma-related guilt. Shame susceptibility as a consequence of negative self-esteem was associated with a greater traumarelated shame. There was no correlation between guilt/shame or trauma-related guilt and PTSD. The time perspective was associated with PTSD - the stronger the tendency of the respondents to focus on the present/past, the greater the symptoms of PTSD. Focusing on the hedonistic present positively correlated with guilt related to trauma. CONCLUSIONS: In the studied population, every second perpetrator of the accident was affected by PTSD, which was associated with the past and present time perspective. Negative assessment of self and behavior intensified the guilt associated with trauma and reduced the search for justification for one's own actions in external circumstances. Time spent in prison had no effect on moral attitudes or on the moral evaluation of one's own behavior that caused harm to others. However, it was associated with experiencing stress and focusing on one's own suffering.

Endometriosis - The challenge for occupational life of diagnosed women: A review of quantitative studies.

The aim of the article was to summarize the results offered in the research on occupational functioning of women with endometriosis. We followed PRISMA guidelines. Database search was done in November 2017 using EBSCO. In the review were included the articles clearly referring to the relationships between endometriosis and work or any aspect of work (e.g., work productivity, work ability, absenteeism). Eight papers were included in the final review. Seven studies were cross-sectional, 1 retrospective. The majority of researchers used standardized research measures, such as Work Ability Index, Work Productivity and Activity Impairment Questionnaire or Health Related Productivity Questionnaire. Only in 2 studies the reference group was considered, one of them consisted of healthy women. The results clearly indicate that endometriosis is a disease that causes major disturbance in occupational functioning of the suffering women. In the future the researchers should search for individual and organizational correlates of the improvement of occupational functioning in this group of patients. The methodology of the existing studies has been evaluated and the methodological cues for future research has been given. Med Pr 2018;69(6):663-671.

Use of work-life balance benefits guaranteed by law in Poland - Do size of the enterprise and gender matter?

BACKGROUND: The paper is aimed at indicating the similarities and differences in use of benefits supporting work-life balance (WLB) between women and men working in Polish small/medium and large enterprises. MATERIAL AND METHODS: The sample included 556 workers (311 women, 245 men), aged 20-68 years old employed on the basis of employment contracts for at least a year in Polish enterprises. The respondents completed a questionnaire on the use of benefits guaranteed by the Polish Labour Code, referring to their current workplaces. RESULTS: Women took maternity leaves and returned to the same work position after using childcare leaves more often than men. Men took leaves on demand more often than women. Our results also showed that in comparison to women working in smaller enterprises, those working in large enterprises were more likely to use almost all the analyzed WLB benefits - paid days off to take care of others, educational leaves, leaves on demand, maternity leaves and return to the same work position after childcare leave, reduction of business trips when pregnant or having young children and breastfeeding breaks. The size of enterprise, however, did not differentiate the take-up of benefits among the studied men. CONCLUSIONS: Our analysis brought unexpected results on the lack of common availability of the WLB benefits guaranteed by the law in the case of employees who worked on the basis of employment contracts. We also found that women used most of child rearing benefits guaranteed by the law more often than men, which might reflect still a traditional division of child care responsibilities in Poland.

Socio-demographic predictors of person-organization fit.

OBJECTIVES: The aim of this study was to explore the relationship between socio-demographic characteristics and the level of complementary and supplementary person-organization fit (P-O fit). MATERIAL AND METHODS: The study sample was a group of 600 Polish workers, urban residents aged 19-65. Level of P-O fit was measured using the Subjective Person-Organization Fit Questionnaire by Czarnota-Bojarska. The binomial multivariate logistic regression was applied. The analyzes were performed separately for the men and women. RESULTS: Socio-demographic variables explained small percentage of the outcome variability. Gender differences were found. In the case of men shift work decreased complementary and supplementary fit, while long working hours decreased complementary fit. In the women, age was a stimulant of a complementary fit, involuntary job losses predicted both complementary and supplementary misfit. Additionally, relational responsibilities increased probability of supplementary P-O fit in the men. CONCLUSIONS: Going beyond personality and competences as the factors affecting P-O fit will allow development of a more accurate prediction of P-O fit.

Availability and the use of work-life balance benefits guaranteed by the Polish Labour Code among workers employed on the basis of employment contracts in small and medium enterprises.

OBJECTIVES: Polish Labour Code provides employees with a range of solutions (benefits) supporting them in achieving balance between work and private life. This paper was aimed at indicating availability and the use of legal benefits supporting work-life balance (WLB) among Polish workers of small and medium enterprises. MATERIAL AND METHODS: The study sample included 219 respondents, aged 22-64, working in small and medium enterprises and employed on the basis of employment contracts for at least a year. The respondents completed a questionnaire on availability and the use of benefits guaranteed by the Polish Labour Code, referring to their current workplaces. RESULTS: Most frequently the studied employees took sick leave because of one's own illness and leave on demand. In our sample, 45% of the women took maternity leave and 26% of the men took paternity leave. The respondents took educational and parental leave the least frequently. More than half of the respondents (58%) did not return to the same position after leave devoted to childcare, even though they had such a possibility. CONCLUSIONS: In fact, most of work-life balance benefits guaranteed by law were available to the employees of small and medium enterprises, regardless of their gender. Availability and the use of the majority of benefits were similar among the women and men. Availability of benefits depended on the specificity of industry and a profession, thus, future research on work-life balance policy should control for variables related to the character of work.

Why do employees follow their superiors' instructions? Identification of the reasons to comply with superiors' will in a group of Polish employees.

BACKGROUND: Managers influence the way organization works as well as the functioning of subordinates - in the context of their work life but non-professional functioning as well e.g., attitude towards work-life balance or taking care of health. We focused on the superior-subordinate relation, referring to social power bases theory by Raven. We identified the reasons why subordinates decide to follow their superiors' orders and determined specific styles of compliance with superiors' will. Understanding why employees listen to their superiors may be valuable in the context of supporting healthy organizational climate and atmosphere of co-operation or communicating values - for example, as regards taking care of own health. We discussed the results referring to the issue of influencing employees in the context of their health behavior. MATERIAL AND METHODS: The research involved 100 Polish employees, aged 28 years old on average, who filled in the Interpersonal Power Inventory by Raven et al. for subordinates in a Polish adaptation by Zaleski. The questionnaire includes 11 subscales referring to power bases. RESULTS: Based on the cluster analysis results, we recognized people who complied because of: all kinds of power bases (typical for 46% of the respondents); the respect for superiors' professionalism (34%); and formal/objective reasons (20%). CONCLUSIONS: Employees differ in terms of their styles of compliance. Their motives to comply with superiors' instructions constitute compilations of power bases. The superiors' awareness of the reasons why their employees decide to follow orders is necessary for successful management. It may motivate employees to work but also to take care of their own health.

Burnout and demographic characteristics of workers experiencing different types of work-home interaction.

OBJECTIVES: The purpose of this study was to explore configurations of positive versus negative interactions between work and home (WHI) and their relation to burnout and demographic characteristics. MATERIAL AND METHODS: Sample of 533 Polish workers were interviewed by means of self-administered questionnaires (SWING and MBI-GS). Demographic and work characteristics were also controlled. RESULTS: Cluster analysis distinguished 5 types of WHIs: positive WHI (18%), negative WHI (15.9%), no interaction (29.3%), mutual positive interactions (15.4%) and positive HWI (21.4%). The quality of WHI was associated with number of work hours and tenure at main place of employment. The effect of gender on the quality of work-home interaction was not significant. Configuration of WHIs affected the level of burnout. Again, there was no significant difference between men and women in terms of burnout and its sub-dimensions. The least burned-out were people from positive WHI, positive HWI and mutual positive interaction groups. The most burned-out were people who experienced negative WHI the most often. In this group, predominance of men working more than 10 h per day was observed. The majority of study group (71%) experienced rather integration than segmentation of both spheres. CONCLUSIONS: Our results suggest that segmentation is not an universal and effective strategy of coping with work and home demands - it may prevent the positive home-work spillover, which can be buffer or remedy against stress or burnout. We consider cluster analysis the appropriate method in research on relation to work-family balance issue, which may be useful in unraveling relationships between this phenomenon and attitudes and behaviors.

[Person-organization fit as a mediator of relationship between work environment and stress among social workers]. / Dopasowanie pracownika do organizacji jako mediator relacji miedzy ocena srodowiska pracy a odczuwanym stresem wsród pracowników socjalnych.

BACKGROUND: Occupational stress of social workers is associated with various psychosocial hazards in the work environment. Some of them affect person-organization fit (P-O fit). The aim of the study was to verify a hypothesis on the mediating role of P-O fit in the relationship between work environment and stress. MATERIAL AND METHODS: The research was based on a sample of 500 social workers directly involved in social work. The data were obtained using the Person-Organization Fit Questionnaire by Czarnota-Bojarska, the Work Environment Questionnaire developed by the Department of Occupational Psychology, Nofer Institute of Occupational Medicine, Lódz, and the Perceived Stress Scale (PSS-10) by Cohen et al. RESULTS: As revealed by the regression analysis of the 4 analyzed work environment factors, only organizational politics was significantly related with perceived stress. Complementary and supplementary dimensions of P-O fit and identification with organization were the mediators of the relationship between organizational policies and stress, but only complementary fit proved to be a total mediator. CONCLUSIONS: The results of the study suggest that person-organization fit, especially its complementary aspect, is an essential determinant of accomplishing the core functions of social work and good practice among social workers.

[Organizational and individual determinants of using initiatives conducive to successful work-life balance]. / Organizacyjne i indywidualne uwarunkowania korzystania z rozwiazan sprzyjajacych równowazeniu zycia zawodowego i prywatnego.

Appropriate distribution of time and energy between work and personal life poses a challenge to many working people. Unfortunately, many professionally active people experience work-family conflict. In order to minimize it, employees are offered various solutions aimed at reconciling professional and private spheres (work-life balance (WLB) initiatives). The authors attempt to answer what makes employees use WLB initiatives and what influences the decision to reject the available options. The review is based on the articles published after 2000, searched by Google Scholar and Web of Knowledge with use of the key words: work-life balance, work-family conflict, work-life balance initiatives, work-life balance initiatives use, use of WLB solutions. We focused on organizational and individual determinants of WLB initiatives use, such as organizational culture, stereotypes and values prevailing in the work environment that may result in stigmatization of workers - flexibility stigma. We discuss the reasons why supervisors and co-workers stigmatize their colleagues, and what are the consequences of experiencing such stigmatization. Among the individual determinants of WLB initiatives use, we have inter alia focused on the preference for integration vs. separation of the spheres of life. The presented material shows that social factors - cultural norms prevailing in a society, relationships in the workplace and individual factors, such as the level of self-control - are of equal importance for decisions of using WLB initiatives as their existence. Our conclusion is that little attention has been paid to the research on determinants of WLB initiatives use, especially to individual ones.

Person-organization fit and organizational identification as predictors of positive and negative work-home interactions.

OBJECTIVES: The aim of the presented research was to explore the links between complementary and supplementary dimensions of Person-Organization fit (P-O fit), organizational identification (OI) and negative (WHI(-)) versus positive (WHI(+)) work-home interactions. It was assumed that both complementary and supplementary P-O fit and OI were positively related to WHI(+) and negatively to WHI(-). MATERIALS AND METHODS: The study was conducted on a large sample of Polish blue and white collar workers. The subjects were interviewed by means of questionnaires measuring: supplementary and complementary dimensions of P-O fit, OI and WHI. General work ability and demographic variables were also controlled in the study, and statistical analysis of ANOVA, pairwise comparison as well as regression were performed. RESULTS: P-O fit and OI differentiated the subjects in terms of WHI. For women supplementary fit was a significant predictor of WHI(-) and explained 12% of its variance, for men it was complementary fit with the number of working days per week and the level of education, which explained 22% of variance. Supplementary fit and OI explained 16% of WHI(+) variance in women; OI, tenure at the main place of employment and the level of education explained 8% of WHI(+) variance in men. CONCLUSIONS: It has been proven that not only are the effects of P-O fit and OI limited to the work environment but they also permeate boundaries between work and home and influence private life - good level of P-O fit and good OI play facilitating role in the positive spillover between work and home. Gender differences in the significance and predictive values of P-O fit and OI for WHI were also found. The innovative aspect of the work is the inclusion of P-O fit and OI in the range of significant predictors of work-home interaction. The results can serve as rationale for employers that improvement of P-O fit and employees' organizational identification should be included in work-life balance programs.

Effect of a 10-week yoga programme on the quality of life of women after breast cancer surgery.

AIM OF THE STUDY: The following research is aimed at determining the effect of yoga on the quality of life of women after breast cancer surgery. MATERIAL AND METHODS: A 10-week yoga programme included 90-minute yoga lessons once a week. To estimate the quality of life, questionnaires developed by the European Organisation for Research and Treatment of Cancer (QLQ-C30 and QLQ-BR23) were used. An experimental group consisted of 12 women who practised yoga, a control group - of 16 women who did not. Between groups there were no differences in age, time from operation and characteristics associated with disease, treatment and participation in rehabilitation. RESULTS: Our results revealed an improvement of general health and quality of life, physical and social functioning as well as a reduction of difficulties in daily activities among exercising women. Also their future prospects enhanced - they worried less about their health than they used to before participating in the programme. As compared to baseline, among exercising women, fatigue, dyspnoea and discomfort (pain, swelling, sensitivity) in the arm and breast on the operated side decreased. CONCLUSIONS: Participation in the exercising programme resulted in an improvement of physical functioning, reduction of fatigue, dyspnoea, and discomfort in the area of the breast and arm on the operated side. Based on our results and those obtained in foreign studies, we conclude that rehabilitation with the use of yoga practice improves the quality of life of the patients after breast cancer surgery. However, we recommend further research on this issue in Poland.

[The occupational, family and health conditions of Polish workers living in urban areas]. / Kondycja zawodowa, rodzinna i zdrowotna pracujacych polaków, mieszkanców miast.

BACKGROUND: This article presents the diagnosis of the socio-economic status and health condition of Polish workers living in urban areas. MATERIAL AND METHODS: The study was conducted in the nationwide group of occupationally active people aged 19-65 years. The interview questionnaire comprised an extensive socio-demographic part and a psychometric part, containing questionnaires measuring the status of mental health, work ability, work satisfaction and family functioning. RESULTS: Slightly more than half of the respondents (54%) worked in occupations related to their profession. The majority (88%) worked full-time, 8 h a day (65%) being employed by 1 employer (92%). Most respondents were satisfied with their job (apart from the financial aspect) and family life; 59% of employees were stressed by their job, including 15% of those who experienced strong stress. The family situation was emphasized by 31% of the respondents. At least one health disorder was diagnosed in 42% of the respondents. Musculoskeletal disorders (19%), cardiovascular diseases (13%) and respiratory disorders (11%) were most frequently reported. At the same time 76% of respondents assessed their health as rather good and good. The mental health index fell within the average values, but 12% of patients reached the score indicating the risk of serious mental health problems. Most of employees assessed their work ability as rather good and good. CONCLUSIONS: The data presented show the direction of the activities that need to be undertaken in the workplace, namely prevention of occupational stress, musculo-skeletal, cardiovascular and respiratory disorders, which significantly limit work ability. It is also necessary to implement educational programs in the workplace. Such activities, if organized on a regular basis, bring the best results.

[Psychological consequences of chronic lungs diseases. The role of medical staff in treatment of psychological problems]. / Psychologiczne konsekwencje przewleklych chorób ukladu oddechowego. Rola personelu medycznego w ich przezwyciezaniu.

Contemporary medicine allows to improve efficiency of sick organs and relief the pain to a large extent, but there is still too little awareness of psychological aspect of suffering among physicians. Although, considerable percentage of people with chronic lungs diseases experience mental disorders such as depression and anxiety, there is no common practice of including psychological care into the treatment protocol. Article highlights the importance of development of knowledge about psychological consequences of chronic lungs diseases among physicians as an early diagnosis of mental health disturbances is crucial for general health status and functioning in this group of patients. Necessity of cooperation with mental health specialists was also shown. It is important to create interdisciplinary teams for improvement of treatment outcomes and and patients' quality of life.

Relationship between person-organization fit and objective and subjective health status (person-organization fit and health).

OBJECTIVE: [corrected] Person-Environment fit (P-E fit) paradigm, seems to be especially useful in explaining phenomena related to work attitudes and occupational health. The study explores the relationship between a specific facet of P-E fit as Person-Organization fit (P-O fit) and health. MATERIALS AND METHODS: Research was conducted on the random sample of 600 employees. Person-Organization Fit Questionnaire was used to asses the level of Person-Organization fit; mental health status was measured by General Health Questionnaire (GHQ-28); and items from Work Ability Index allowed for evaluation of somatic health. Data was analyzed using non parametric statistical tests. The predictive value of P-O fit for various aspects of health was checked by means of linear regression models. RESULTS: A comparison between the groups distinguished on the basis of their somatic and mental health indicators showed significant differences in the level of overall P-O fit (χ(2) = 23.178; p < 0.001) and its subdimensions: for complementary fit (χ(2) = 29.272; p < 0.001), supplementary fit (χ(2) = 23.059; p < 0.001), and identification with organization (χ(2) = 8.688; p = 0.034). From the perspective of mental health, supplementary P-O fit seems to be important for men's well-being and explains almost 9% of variance in GHQ-28 scores, while in women, complementary fit (5% explained variance in women's GHQ score) and identification with organization (1% explained variance in GHQ score) are significant predictors of mental well-being. Interestingly, better supplementary and complementary fit are related to better mental health, but stronger identification with organization in women produces adverse effect on their mental health. CONCLUSIONS: The results show that obtaining the optimal level of P-O fit can be beneficial not only for the organization (e.g. lower turnover, better work effectiveness and commitment), but also for the employees themselves. Optimal level of P-O fit can be considered as a factor maintaining workers' health. However, prospective research is needed to confirm the results obtained in this exploratory study.

[Visual abilities of older drivers--review of driving simulator studies]. / Zdolnosci wzrokowe starszych kierowców--przeglad badan symulatoro wych.

In the member countries of the year Organization for Economic Co-operation and Development (OECD), one in four people will reach the age of 65 or more by 2030 and their population aged over 80 will triple by 2050. Changes that occur in the demographic structure of developed countries will affect traffic area. Most of the on-road existing solutions is inadequate for older people with diminished cognitive and motor abilities. In this group, difficulties in driving performance are associated with reduced cognitive efficiency, vision and hearing loss, and general psychomotor slowing. The presented review focuses on the studies of a useful field of view, an indicator considered to be a valid predictor of road accidents, divided attention, susceptibility to distraction and visual search strategies. The major questions of these studies were: which vision parameters determine safe driving, what degree of their deterioration causes significant risk and whether there are opportunities for their rehabilitation. The results indicate that older drivers do exhibit vision and attention deficits, but their engagement in a wide range of compensatory behaviors and effective visual search strategies compensate for these deficits. This shows that older drivers cannot be clearly classified as a group of particular risk for causing road traffic accidents. We should not be alarmed by a growing group of active senior drivers. We should rather use the advantages of available methods, including driving simulators, to predict how the traffic environment will look like in the close future and how to make it friendly and safe for everyone.

[Person-organization fit and work ability]. / Dopasowanie do organizacji a ocena zdolnosci do pracy.

BACKGROUND: Person-environment issue has long been in focus of researchers who explore the area of human labor. It is known that the level of fit is a predictor of many phenomena related to health and attitude to work. The aim of this study was to explore the association between the level of person- organization fit (P-O fit) and work ability, including indicators of somatic and mental health. MATERIALS AND METHODS: Research was conducted on a representative sample of 600 Polish men and women at working age. The Person-Organization Fit Questionnaire was used to assess three dimensions of P-O fit (supplementary fit, complementary fit and identification with organization); mental health status was measured by GHQ-28; the number of diagnosed diseases was taken as an index of somatic health; work ability, ability to physical and mental efforts were measured by three items from the Work Ability Index. RESULTS: A significant relationship between P-O fit level and work ability was found. In men, work ability predictors were: age, supplementary fit and mental health status, which explained 25% of the variance in work ability. In women, work ability predictors were: the number of diagnosed somatic diseases, supplementary fit, age and complementary fit, which explained 27% of the variance in work ability. Some gender-related differences in the predictive value of variables under the study were also found. CONCLUSIONS: The results of this study indicate the importance of P-O fit in shaping the sense of work ability, a recognized predictor of workers' occupational activity and the frequency of taking sick leave in subsequent years. Therefore, this result may be a useful argument to motivate employers to employ workers adequately to their abilities and preferences.

[Effects of marijuana and amphetamine (and its derivatives on driving performance based on the driving simulator studies]. / Wplyw zazywania marihuany i amfetaminy (oraz jej pochodnych) na prowadzenie pojazdów na podstawie wyników badan symulatorowych.

This article presents the results of the driving simulator studies of the effects of marijuana and amphetamines on driving performance. The majority of these studies have been focused on identifying the impact of the tested substances on cognitive and psychomotor functions. Most of the findings on marijuana reveal its modest effect on driving ability that increases with the increasing frequency of its use and when used in conjuction with other drugs and alcohol. Similarly, small doses of amphetamines can cause a positive stimulating effect, improving certain cognitive functions, such as vigilance, but it decreases when they are overused and combined with alcohol. The results of the research on drivers' behavior under the influence of amphetamines also indicate deficits in their cognitive functions and tendency to recklessness on the road. The authors also discuss strong and weak points of simulation studies of the effects of psychoactive substances on the driving ability. An attempt was also made to clarify certain ambiguities, which occur in this field of research. A central role of the ethical and methodological limitations of simulation studies were discussed as well.
