Circadian rhythm and sleep disruptions in relation to prenatal stress and depression symptoms.

Circadian rhythm and sleep are related to health, but there is little data on the relationship between the sleep/wake rhythm and mood at different stages of pregnancy. The aim of this prospective, longitudinal study was to investigate the associations of circadian rhythm and sleep disruptions with stress and depression among women in early and late pregnancy. The participants were 26 pregnant women. Objective and subjective estimations of circadian rhythm and sleep were administered, namely actigraphy and the Biological Rhythms Interview of Assessment in Neuropsychiatry in the form of a questionnaire. The Perceived Stress Scale and the Edinburgh Postnatal Depression Scale were also used. Subjectively perceived circadian rhythm disruptions were positively related to stress. Tendency to maintain a regular rhythm of sleep and activity in early pregnancy and subjectively perceived disruptions of circadian rhythms in late pregnancy were positively associated with prenatal depression in late pregnancy. Sleep fragmentation and long time spent in bed at night in early pregnancy were positively associated with stress and depression in late pregnancy. The results suggest the importance of flexibility and the ability to adapt one's circadian activities to the demands of the situation of pregnancy-related changes in lifestyle. They also indicate the significance of good-quality uninterrupted night sleep in early pregnancy.

What Is Behind the Buzzword for Experts and Laymen: Representation of "Artificial Intelligence" in the IT-Professionals' and Non-Professionals' Minds.

The aim of the presented research was to define the differences between information technology (IT) professionals (ITP) and non-professionals (NP) in the way of understanding artificial intelligence (AI). The research was designed in the tradition of categorization research. In an online study participants were asked to make typicality and familiarity judgments for 50 AI exemplars. Two types of analyses were carried out, which made it possible to identify and compare the hierarchy of AI designates (graded structure) and the dimensions of their groupings. We have found that "invisible AI" exemplars were highly rated by ITP, but "visible AI" by NP. Expert knowledge allows ITP to systematize AI exemplars based on both structural and functional elements. On the other hand, laymen indicate the functions that AI-driven products perform, rather than their structures. For ITP, they are primarily algorithmic systems, while for NP they are systems that emulate the functions of living organisms.

The Impact of Our Personality on Others: The Lithuanian Comprehensive Lexical Taxonomy of Social Effects.

Social effects represent the psychological (emotional, cognitive, and motivational) reactions evoked in other people by the expression of traits in behavior and emotion. From the transactional view on personality, studying the psycholexical structures of social effects can help to discover unique vs. common thought and behavior patterns, affects, and motivations, which are primarily related to personality dispositions. Thus, we developed the comprehensive taxonomy of social effects following the principles of the psycholexical approach. In the first study, two judges selected 9,625 person-descriptive terms-adjectives, type-nouns, attribute-nouns, and participles-from the Dictionary of the Standard Lithuanian Language. In the second study, six judges classified all the selected descriptors using German psycholexical methodology. Finally, a principal component analysis was performed, followed by varimax rotation for the 208 social-effect descriptors, separately for ipsatized self-ratings and observer-ratings from 203 to 204 Lithuanian students, respectively. We found out that the five-component solution was the best fit for self-ratings, whereas for observer-ratings it was a four-component structure. In this article, we present the results from the factor analyses and discuss our findings in the context of previous studies, as well as cross-language personality models.

Materialism, conspicuous consumption, and brand engagement in self-concept: a study of teenagers.

BACKGROUND: Contemporary adolescents, also known as Generation Z, are an important group of consumers due to the role they play in today's economy. The present study investigates the relationship between materialism and brand engagement in self-concept (BESC) and whether conspicuous consumption is a mediator of this relationship in early, middle, and late adolescence. PARTICIPANTS AND PROCEDURE: The participants were 581 students from Poland, aged 13 to 17 (M = 15 years, SD = 1.42); 51.6% of them were girls. Data were gathered using a demographic information form, the Youth Materialism Scale, the Conspicuous Consumption Scale, and a BESC Scale, completed during personal interviews. RESULTS: The study indicated an association of higher materialism and higher conspicuous consumption with a higher level of BESC, where conspicuous consumption acts as a mediator of the correlation between materialism and BESC. Age also moderates this mediation, i.e., the older the teenagers are, the weaker is the analyzed mediation effect. CONCLUSIONS: The research is part of an essential step in understanding the mechanism of BESC by testing a moderated mediation model in teenagers.

Validation and Psychometric Properties of the HEXACO Personality Inventory Observer Report Form in the Polish Language.

The aim of this study was to verify the structure and psychometric properties of the Polish adaptation of the HEXACO-PI-R observer report form based on a heterogeneous target sample (liked, neutral and disliked peers). The vast majority of research has focused on the validity and reliability of the self-report form. The psychometric properties of the observer report version have been verified in only two languages. Previous Polish lexical studies based on a heterogeneous target sample have shown that the structure differs from a typical six-factor structure from self-rating studies. Since this phenomenon was not observed in English, we decided to verify the psychometric properties of the observer report form in Polish. Additionally, the NEO-FFI and Polish Personality Markers for observer report were used. All HEXACO-PI-R scales achieved satisfactory internal consistency and showed high stability. The results indicated that the structure of the Polish adaptation of the HEXACO-PI-R observer report form could be considered as similar to the theoretical construct, except when the target of the description is neutral for the respondent. This suggests the necessity to verify the structure of the HEXACO-PI-R observer report form based on liked and disliked peers in other languages as well.

Cultural Management of Terror and Worry During the COVID-19 Pandemic: How Religiosity and a Dream of Human Solidarity Help the Polish People Cope.

The COVID-19 pandemic, which involves the threat of contracting a potentially fatal disease, can be understood as a source of terror. According to terror management theory, people shield themselves from terror by adopting culturally specific worldviews and protecting self-esteem. The study investigates the protective role of worldviews that are culturally specific to Poles: religiosity and social solidarity. The hypothesis was that Poles who tend to worry, entertain these worldviews and are more likely to maintain high self-esteem and concentrate on the current moment (carpe diem), which theoretically allows them to reduce future-related anxiety. Path analysis confirmed that self-esteem, the centrality of religiosity, and expectation of solidarity due to the COVID-19 pandemic mediate the relationship between the worry trait and carpe diem.

Facebook Intrusion as a Mediator Between Positive Capital and General Distress: A Cross-Cultural Study.

Background: Social networking sites (SNSs) play an important role in many aspects of life nowadays, and it seems to be crucial to explore their impact on human well-being and functioning. The main aim of the study was to examine the mediating role of Facebook intrusion between positive capital and general distress. Positive capital was considered as comprising self-esteem, ego-resiliency, and self-control, while general distress was seen as having three dimensions: depression, anxiety, and stress. Methods: The sample consisted of N = 4,495 participants (M = 22.96 years, SD = 5.46) from 14 countries: Australia, Cyprus, Greece, Hong Kong, Lithuania, New Zealand, Peru, Poland, Russia, Spain, Turkey, Ukraine, United Kingdom, and United States. We used the following methods: the Facebook Intrusion Questionnaire (FIQ), the Self-Esteem Scale (SES), the Brief Self-Control Scale (SCS), The Ego Resiliency Revised Scale and the Depression, Anxiety, and Stress Scale-21 (DASS-21). Results: We found that Facebook intrusion was a mediator between self-esteem and general distress and between self-control and general distress. Limitations: The present study was based on a cross-sectional study, and the measures used were self-report measures. The majority of the participants were recruited using convenience sampling. Conclusions: The present findings contribute to a better understanding on how the social media have impact on individual mental health. Implications for future studies are discussed.

Measurement invariance of the Phubbing Scale across 20 countries.

Mobile phone addiction is a robust phenomenon observed throughout the world. The social aspect of mobile phone use is crucial; therefore, phubbing is a part of the mobile phone addiction phenomenon. Phubbing is defined as ignoring an interlocutor by glancing at one's mobile phone during a face-to-face conversation. The main aim of this study was to investigate how the Phubbing Scale (containing 10 items) might vary across countries, and between genders. Data were collected in 20 countries: Belarus, Brazil, China, Croatia, Ecuador, India, Israel, Italy, Netherlands, Pakistan, Poland, Portugal, Serbia, Slovakia, Slovenia, Spain, Turkey, UK, Ukraine and USA. The mean age across the sample (N = 7696, 65.8% women, 34.2% men) was 25.32 years (SD = 9.50). The cross-cultural invariance of the scale was investigated using multigroup confirmatory factor analyses (MGCFA) as well as the invariance analyses. Additionally, data from each country were assessed individually via confirmatory factor analyses (CFAs). We obtained two factors, based on only eight of the items: (a) communication disturbances and (b) phone obsession. The 8 items Phubbing Scale.

The Psychological and Academic Effects of Studying From the Home and Host Country During the COVID-19 Pandemic.

Objective: This study explored the psychological and academic effects of studying online from the home vis-à-vis host country during the coronavirus disease 2019 (COVID-19) pandemic in the experience of international students at the University of Warsaw, Poland. Methods: A total of 357 international students from 62 countries (236 in the host country and 121 in the home country) completed an online questionnaire survey 2 months after transition to online learning. We studied students' levels of loneliness, life and academic satisfaction, acculturative stress, academic adjustment, performance, loyalty, and perceptions of the online learning experience. Results: The country-of-residence variable had no statistically significant effects on most psychological and academic variables. Significant effects were observed only for two academic variables. Specifically, students who returned to the home country found online communication with other students more contributing to their online learning experience and exhibited higher academic adjustment than students who remained in the host country. This suggests the positive influence of (peer and familial) support on online learning experience from the home country. Furthermore, a significant difference in experiencing acculturative stress occurred for students in quarantine/self-isolation in the host country, which expands prior literature on the disruptive effects of social distancing on students' mental health. Finally, this study confirmed the expected increased levels of loneliness among self-isolating students in both countries, hence extending prior results to the home- and host-country contexts. No relationship between self-isolation and students' life or academic satisfaction was found, which is explained by the specific nature of the learning-from-home experience.

Country Indicators Moderating the Relationship Between Phubbing and Psychological Distress: A Study in 20 Countries.

Problematic mobile phone use can be related to negative mental states. Some studies indicate that behavioural dependency is related to variables associated with the country of origin. The aim of our study was to investigate if country indicators moderated the relationship between phubbing and psychological distress. Our sample consisted of 7,315 individuals from 20 countries, who completed the Phubbing Scale and the Kessler Psychological Distress Scale (K6). The analyses also included country indicators: the Gender Gap Index (GGI), the Human Development Index (HDI), the Social Progress Index (SPI), Hofstede's dimensions of culture, and the World Happiness Index (WHI). Our results showed that psychological distress was related to at least one dimension of phubbing (i.e., to communication disturbance or phone obsession) in all countries, which means this relationship is culturally universal. The results of the study demonstrate the importance of testing measurement invariance to determine what type of analysis and what type of conclusion are valid in a given study or comparison. Moreover, the increasing or decreasing correlation between phubbing and distress is related to some culture-level indices.

The Development of Understanding Opacity in Preschoolers: A Transition From a Coarse- to Fine-Grained Understanding of Beliefs.

Intensionality (or opacity) is a core property of mental representations and sometimes understanding opacity is claimed to be a part of children's theory of mind (evidenced with the false belief task). Children, however, pass the false belief task and the intensionality tasks at different ages (typically 4 vs. 5;1-6;11 years). According to two dominant interpretations, the two tests either require different conceptual resources or vary only in their executive or linguistic load. In two experiments, involving 120 children aged 3-6 (Experiment 1) and 75 children aged 4-6 (Experiment 2), we tested two variants of the executive load hypothesis: The differential linguistic complexity of the two tests, and the dual-name problem of the intensionality task. The former was addressed by standardizing and minimizing the linguistic demands of both tasks (contrasted with the typical narrative intensionality task), and the latter by introducing the dual-name problem into the false belief task as well, so that it was present in both tasks. We found that (1) two structurally different intensionality tasks shared more variance with each other than with the structurally similar false belief task, and that (2) introducing a dual label problem into the false belief task did not reduce the developmental gap. Our results speak against interpreting the difference between the time children pass the two tests entirely in terms of performative issues, and support the conceptual enrichment hypothesis. We discuss the theoretical relevance of these results, suggesting that they are best explained by fine-grained increments within the concept of belief, rather than a radical conceptual change. We conclude that understanding opacity of minds - which emerges between age 5 and 6 - is an important step toward a more advanced form of ToM.

Mobile Phone Addiction, Phubbing, and Depression Among Men and Women: A Moderated Mediation Analysis.

For several years, the number of studies on the links between excessive mobile phone use and mental health has been increasing. The aim of the study was to establish if there is a relationship between mobile phone addiction and depression in university students and if phubbing is a mediator of this relationship. The authors also tested if this mediation effect was moderated by loneliness and if the model of relationships between these variables was the same in women and in men. The participants were 402 university and college students from Ukraine, aged 17 to 31; 74% of them were women. The authors used the Adapted Mobile Phone Use Habits, the Phubbing Scale, the Center for Epidemiologic Studies Depression Scale, and the Loneliness Scale. The results of the study have shown that higher mobile phone addiction and higher phubbing is associated with a higher level of depressive moods, with phubbing functioning as a mediator of the relationship between mobile phone addiction and depression. A moderator of this mediation is loneliness, the moderation effect being asymmetrically dependent on gender: in men, high loneliness increases the mediating role of phubbing, which more markedly translates into depression, while in women the analyzed mediation effect becomes weaker with an increase in the sense of loneliness (phubbing correlates less strongly with depression).

Severity of post-traumatic stress symptoms, level of experienced stress and coping strategies in mothers of children previously treated in the neonatal intensive care unit. / Nasilenie objawów stresu pourazowego i poziom odczuwanego stresu a strategie radzenia sobie ze stresem u matek dzieci w przeszlosci leczonych na oddziale intensywnej terapii noworodka.

OBJECTIVES: The aim of the study was to develop a model of the relationship between the severity of post-traumatic stress symptoms, levels of experienced stress and coping strategies in mothers of children previously treated in neonatal intensive care units. METHODS: Anonymous questionnaire survey covered 62 mothers of infants aged from three to 12 months who had previously been hospitalized in neonatal intensive care units. Respondents completed a questionnaire comprising standardized tools such as the Impact Event Scale - Revised (IES-R), COPE Inventory and Perceived Stress Scale (PSS-10). RESULTS: The severity of PTSD symptoms is explained by the model comprising four variables: three stress coping strategies (focus on and venting of emotions, denial and mental disengagement) and perceived stress. The model explains nearly 40% of post-traumatic stress symptoms. Perceived stress partly affects PTSD through one stress coping strategy - denial, which also has the effect on post-traumatic stress symptoms severity regardless of perceived stress. CONCLUSIONS: Focus on and venting of emotions, denial, mental disengagement, and the level of perceived stress are potentially modifiable factors that are strongly associated with PTSD. Planning, realization and assessment of interventions aimed at reduction of maladaptive coping strategies and perceived stress are recommended for mothers of infants requiring treatment in neonatal intensive care units. In order to minimize distress and improve coping with the treatment of the child, it is necessary to evaluate the effects of various methods of supporting parents.

An international survey of perceptions of the 2014 FIFA World Cup: National levels of corruption as a context for perceptions of institutional corruption.

We conducted a survey about the 2014 FIFA World Cup that measured attitudes about FIFA, players, and officials in 18 languages with 4600 respondents from 29 countries. Sixty percent of respondents perceived FIFA officials as being dishonest, and people from countries with less institutional corruption and stronger rule of law perceived FIFA officials as being more corrupt and less competent running the tournament than people from countries with more corruption and weaker rule of law. In contrast, respondents evaluated players as skilled and honest and match officials as competent and honest. We discuss the implications of our findings for perceptions of corruption in general.

Cultural Correlates of Internet Addiction.

Increasing problems connected with excessive Internet use can be observed all over the world. Internet addiction is defined as excessive involvement in the Internet with negative consequences. The main aim of the study was to investigate economic indicators as correlates of Internet addiction. The study was conducted in nine countries. The number of participants amounted to a total of 3,279 Internet users (54% were female), with a mean age of M = 25.14 (SD = 10.03). The authors used Young's Internet Addiction Test. In addition, some social and economic indicators characterizing the countries were taken into consideration. We found that Internet addiction was positively related to economic well-being, social progress, and human development as well as negatively related to human well-being, health, safety, and security. The results of the study contribute to the international debate on Internet addiction.

Body image in perimenopausal women.

INTRODUCTION: Menopause is the last natural menstruation, followed by a period of 12 months during which no bleeding occurs (WHO). This natural process results from the phasing out of the physiological activity of the ovaries and involves numerous psychological and somatic disturbances. Although perimenopausal ailments are experienced by most women, the correlation between their perception of the bodies and biopsychosocial functioning in the climacteric period is not fully understood. The aim of the study was to determine whether women's body image varies depending on the period of their reproductive life. MATERIAL AND METHODS: 113 women aged 25-60 were examined (both menopausal and postmenopausal) with the control group comprising 58 women. The following scales were used: the Appearance-Related Picture Self-Appraisal Form and the Appearance Self-Appraisal Scale. RESULTS: The study demonstrated statistically significant differences between the groups on 7 scales and the overall score. It can be said that postmenopausal women, whose ovarian activity has nearly ceased, in comparison with those in the premenopausal and menopausal groups attribute lower importance to the following areas of the body: eyes, nose, mouth, stomach, buttocks, thighs, and calves. The mean values of satisfaction in the three groups under comparison were not statistically different. CONCLUSIONS: The subjects of the postmenopausal group attribute lower importance to different body areas, deriving greater satisfaction from their own bodies.
