Abstract

Introduction. Social networking sites are virtual online communities, where users can design personal profiles available for public assessment, interact with friends, and meet with others, based on shared interests. SNS (social networking sites) have been defined as a “global consumer phenomenon” because they have been experiencing a sharp increase in popularity and use over the last decade. SNS websites, such as Facebook, are becoming increasingly popular, however, little is known about psychosocial variables, which are risk factors for excessive use of these websites.

Aim. The aim of the work was to characterize personality traits (self-image characteristics, ways of coping with stress and aggression intensity) of youth who have a profile on a social networking site.

Material and methods. The study included a total of 590 individuals from 16 to 18 years of age. Among the subjects, a group of 51 people without a profile was identified and 539 – with a profile on a social networking site. The group of teenagers was examined by means of statistical methods: a socio-demographic survey by the authors’ own design, H. G. Gough and A. B. Heilbrun’s Adjective Check List (ACL), Stress Coping Questionnaire (SCQ) constructed by W. Janke, G. Erdmann, K. W. Kallus, in the Polish language compilation by E. Januszewska, Buss-Durkee Hostility – Gild Inventory, developed in Polish by Choynowski.

Results. Statistically significant differences were found in terms of self-image features, ways of coping with stress and activity displayed on the Internet between the youth who had and did not have a profile on the social networking site.

Conclusions. Significantly more young people who have a profile on a social networking site share their personal data with strangers met through the Internet, use internet services and make purchases online, compared to the youth who do not have this profile. Young people with a profile on a social portal are characterized by greater timidity, difficulties in coping with stress and everyday tasks, less perseverance, entrepreneurship, effectiveness in the implementation of tasks, less self-confidence, less autonomy, responsibility and tolerance in comparison with young people who do not have a profile. Young people who have a social media profile are more likely to turn to other people in a stressful situation to request support and advice.

Abstract

The aim of the present study was to provide an answer to the question of whether, and what, differences in stress coping strategies could be found between university students at risk and those not at risk of mobile phone addiction. The study included 408 students aged 19 to 28 years. The following instruments were used: a sociodemographic questionnaire, the Mobile Phone Addiction Assessment Questionnaire (in Polish, Kwestionariusz do Badania Uzależnienia od Telefonu Komórkowego, KBUTK) by Pawłowska and Potembska, and the Coping with Stress Questionnaire (SVF) by Janke, Erdmann, and Boucsein, translated into Polish by Januszewska. The results of the study showed that individuals at risk of mobile phone addiction were more likely to cope with stress by seeking substitute gratification, reacting with resignation, passivity, dejection and hopelessness, blaming themselves, pitying themselves and looking for support. They also tended to ruminate over their suffering, withdraw from social interactions, react with aggression and/or take to drinking.

Conclusions. 1. Alcohol addicted women who were raised by parents with alcohol dependence are characterised by more negative self-image, greater need for getting support, dependence, fear of negative assessment by other people, passive ways of coping with stress and aggression not directly expressed - in comparison to the women raised by not addicted parents. 2. Men raised by alcohol addicted parents are characterised by greater narcissism and more often expressed physical aggression in comparison to men raised by not addicted parents.

Abstract

This article describes the psychometric properties of the Disease Perception Questionnaire (Kwestionariusz Obrazu Choroby, KOCh, in Polish). An original version of KOCh consisting of 99 items was used to survey a group of 161 subjects aged 25 to 85 years. On the basis of factor analysis, four factors (scales) were identified which pointed to the subjects’ different perceptions of their disease: (1) Disease as a Threat, (2) Disease as a Weakness, (3) Disease as a Task, and (4) Disease as a Benefit. Items with the lowest factor loadings and the lowest factor specificity indexes were rejected. The factors identified explained 38% of the total variance. The final version of the KOCh questionnaire consisted of 57 items. The coefficients of reliability for the individual factors were Cronbach’s alpha = 0.94 for Disease as a Threat, Cronbach’s alpha = 0.86 for Disease as a Weakness, Cronbach’s alpha = 0.84 for Disease as a Task, and Cronbach’s alpha = 0.85 for Disease as a Benefit

Abstract

Introduction. Increased suicide rates, both among adults and adolescents, have been seen in Poland over recent years.

Aim. The aim of the study was to determine the prevalence of self-injury, suicide ideation, plans and attempts in adolescents aged 13 to 19 years.

Material and methods. The study encompassed the total number of 6883 individuals aged 13 to 19 years, 69% of them being girls and 31% - boys. All respondents lived in Lubelskie Province. The research was conducted using a questionnaire designed by the authors.

Results. In the group composed of 6883 adolescents living in Lublin Province, suicide ideation was reported by 47.65% of the respondents, suicide plans by 32.35%, suicide attempts were carried out by 10% of adolescents and self-injury by 24.91% of the respondents aged 13 to 19 years.

Conclusions. The greatest prevalence of suicide ideation, plans and attempts, as well as self-injuries, were recorded in the group of adolescents aged 17. The adolescents living in the urban areas are more likely to inflict self-injury than those living in rural areas. Furthermore, adolescents with suicidal tendencies, e.g. attempting suicide and self-injury, are more prone to alcohol and substance abuse. It needs emphasizing that many adolescents with suicidal tendencies, compared against those who did not carry them out, have past experience of psychological, physical and sexual violence in the family, have been raised by a single parent or in families, where one of the parents abused alcohol.

Abstract

The aim of this paper was to determine differences and similarities between city dwelling teenagers aged 13–17 years who consumed/did not consume alcohol and their rural counterparts in regard to the severity of Internet addiction symptoms.

Participants and methods: The examined group consisted of 1,191 people (890 girls and 301 boys) aged 13–17 years. The following instruments were used in the study: a sociodemographic questionnaire designed by the present authors, the Internet Addiction Questionnaire designed by Potembska, and the Internet Addiction Questionnaire (KBUI) designed by Pawłowska and Potembska.

Results: The results show that adolescents who consume alcohol, both those living in urban and rural areas, are characterized by statistically significantly more severe Internet addiction symptoms measured by KBUI as compared to their non-drinking peers.

Conclusions:

  1. Adolescents who consume alcohol, both urban and rural residents, are characterised by statistically significantly more severe symptoms of Internet addiction compared to their peers who do not consume alcohol.
  2. Adolescents who live in a city and who consume alcohol are significantly more likely to use Internet pornography than their non-drinking peers.
  3. Adolescents who live in urban areas are significantly more likely to use Internet pornography, play violent computer games and search for acceptance and understanding only in online interactions as compared to adolescents who do not consume alcohol.
  4. Underage city-dwellers who consume alcohol are significantly more likely to use electronic mail, instant messaging and web pages compared to their rural peers.

Abstract

Aim. The study was to assess the level of stress and the health locus of control in parents of hospitalized newborns.

Material and methods. The study covered a group of 150 parents of 126 newborns who were hospitalized in the Neonatal Pathology Ward at the University Children’s Hospital in Lublin. The diagnostic survey method was applied with the use of an original questionnaire as well as some standardized tools: Perceived Stress Scale (PSS-10) and Multidimensional Health Locus of Control Scale (MHLC – version B).

Results. In more than a half of the subjects (54.0%), a high level of stress was observed. Every fourth (26.1%) parent was characterized by an average level of stress and nearly every fifth (19.3%) by a low level of stress. The highest indicator was characterized by the domain of the internal health control locus. Every fifth parent represented an undifferentiated type - weak or magnifying the impact of others (22.0% and 20.0% respectively). The smallest group of parents (5.3%) belonged to the externally-oriented, strong type. Conclusions. The parents of hospitalized newborns are characterized mainly by high and average levels of stress and low level of severity of health control location within each of its domains. The highest indicator of internal locus control and the influence of others are characterized by parents with low and average levels of stress. The dominant type of locus of health control that characterizes parents is the undifferentiated type – weak and magnifying the impact of others.
