Validation and Psychometric Properties of the Polish Version of the Skin Picking Scale-Revised.

The Skin Picking Scale-Revised (SPS-R) is an 8-item self-report measure of skin picking behaviors. It includes two subscales related to skin picking symptom severity and picking-related impairments. The study aimed to assess the psychometric properties of the Polish version of the SPS-R in a sample of adults reporting skin picking. The sample of 764 participants was recruited from the general population through an online survey. Among them, 159 meet the criteria of pathological skin picking applied in the original SPS-R validation study, and 57 endorsed all of the DSM-5 criteria for excoriation disorder. The SPS-R was back-translated into Polish. Factor structure, reliability, convergent and divergent validity, and diagnostic accuracy were assessed. Confirmatory factor analyses revealed a two-factor structure of the scale. High internal consistency and convergent and divergent validity were confirmed for the total score as well as for the subscales. High prognostic ability of the SPS-R total score was also demonstrated using ROC analysis: ≥5 was accepted as an optimal cut-off point for distinguishing skin picking sufferers from healthy controls. The Polish version of the SPS-R shows good psychometric properties and appears to be a reliable measure of skin picking symptoms and picking-related impairment.

The Mediating Role of Stress in the Relationship Between Attention to Threat Bias and Psychotic-Like Experiences Depends on Coping Strategies.

AIM: Recent studies have provided evidence that enhanced stress level is associated with the increase of psychotic symptoms in both clinical and non-clinical populations. It has also been demonstrated that cognitive biases contribute to psychotic experiences. However, it remains unclear whether the effect of cognitive biases and perceived stress on psychotic-like experiences (PLEs) is influenced by coping methods. In the present study we examined whether the relationship linking cognitive biases with PLEs is mediated by the level of stress and whether particular coping methods modify the relationship between stress and PLEs. METHODS: The study sample consisted of 290 non-clinical subjects; study variables were assessed by questionnaires. Moderated mediation analyses were conducted. RESULTS: Perceived stress was found to serve as a partial mediator in the relationship linking attention to threat (ATB) and external attribution biases (ETB) with psychotic-like experiences. Also, moderated mediation analysis revealed that the indirect effect of attention to threat bias on positive and depressive symptoms of psychotic-like experiences via perceived stress was stronger at higher levels of distraction seeking coping. Moreover, the indirect effect of ATB on depressive symptoms was moderated by task-oriented coping and emotion-oriented coping. Task-oriented coping also moderated the indirect effect of ETB on depression. CONCLUSION: The findings imply that both perceived stress and coping styles are important factors affecting the association between cognitive biases and psychotic-like experiences.

Bioethical dilemmas of assisted reproduction in the opinions of Polish women in infertility treatment: a research report.

Infertility Accepted treatment is replete with bioethical dilemmas regarding the limits of available medical therapies. Poland has no legal acts regulating the ethical problems associated with infertility treatment and work on such legislation has been in progress for a long time, arousing very intense emotions in Polish society. The purpose of the present study was to find out what Polish women undergoing infertility treatment think about the most disputable and controversial bioethical problems of assisted reproduction. An Attitudes towards Bioethical Problems of Infertility Scale was constructed specifically for this study. Items were taken from the Bioethics Bills currently under discussion in Polish Parliament (Seym). 312 women were enrolled in the study. Women experiencing infertility favoured more liberal legislation. Participants disagreed, for example, with the following regulations: prohibition of embryo freezing, prohibition of preimplantation genetic diagnosis of embryos, age limits for women using in vitro fertilisation and prohibition of in vitro fertilisation for single women. The opinions of patients undergoing infertility treatment are an important voice in the Polish debate on the Bioethics Bills.
