Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence) are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference-matching (i.e., do people positively evaluate partners who match versus mismatch their ideals?) has become mired in several problems. For one, articles exhibit discrepant analytic and reporting practices. Furthermore, different findings emerge across laboratories worldwide, perhaps because they sample different relationship contexts and/or populations. The current project—partnered with the Psychological Science Accelerator—can bring clarity to this literature. This registered report uses a highly powered design across multiple world regions to calculate preference-matching effect sizes and variability estimates for all relevant analytic tests. It also examines effects in different relationship contexts and subsamples (e.g., attraction, established relationships, recently formed relationships).

The interest in the association between feelings of guilt and shame and psychological health is growing. However, less attention so far has been paid to the associations with chronic disease. Therefore, the aim of this study was to explore whether feelings of guilt and shame are related to physical health in chronic disease and in selected ones. A nationally representative sample of Czech adults (n = 1000, age = 46.0 +/- 17.3 years, 48.6% men) participated in the survey. Feelings of guilt and shame (items from The Positive and Negative Affect Schedule) and health problems in selected chronic diseases were measured. Respondents with higher feelings of guilt - but not of shame - were more likely to suffer from a chronic disease; we found this in arthritis, back pain, cardiovascular disease, asthma, cancer and depression or anxiety. The association was strongest in the case of cancer with odds ratios (OR) 5.83 (95% confidence interval (CI) 2.27-16.69). There were no significant associations in case of diabetes and stroke. Feelings of shame were not related to chronic diseases. Our findings suggest that feelings of guilt are associated with worse physical health. Further research is needed in this area.

Research in some religious countries shows that religiosity and spirituality positively affect adolescent health. We studied whether religiosity and spirituality also have positive associations with adolescent health in a secular country. We tested the associations between religious attendance and spirituality and self-reported health and health complaints using a representative sample of Czech adolescents (n = 4182, 14.4 &plusmn, 1.1 years, 48.6% boys) from the 2014 health behavior in school-aged children (HBSC) study. We used religious attendance, the adjusted shortened version of the spiritual well-being scale (SWBS), and its two components&mdash, religious well-being (RWB) and existential well-being (EWB)&mdash, as independent variables and the eight item &ldquo, HBSC symptom checklist&rdquo, and self-reported overall health as dependent variables. A higher level of spirituality was associated with lower chances of health complaints and self-reported health, ranging from a 9% to 30% decrease in odd ratios (OR). Religious attendance was not associated with any of the observed variables. The EWB showed a negative association with all of the observed variables, with associations ranging from a 19% to 47% decrease. The RWB was associated with a higher risk of nervousness (OR = 1.12), while other associations were not significant. Non-spiritual but attending respondents were more likely to report a higher occurrence of stomachache (OR = 2.20) and had significantly worse overall health (OR = 2.38). In a largely secular country, we found that spirituality and the EWB (unlike religious attendance and the RWB) could have a significant influence on adolescent health.

Most studies on the coronavirus pandemic focus on clinical aspects of the COVID-19 disease. However, less attention is paid to other health aspects of the pandemic. The aim of this study was to assess the relationship between the coronavirus pandemic (risk of infection by virus together with associated measures taken to combat it), and the occurrence of a wide range of psychosomatic symptoms and to explore if there is any factor that plays a role in this association. We collected data from a sample of Czech adults (n = 1431) and measured the occurrence of nine health complaints, respondents’ experience during the pandemic and sociodemographic characteristics. The results showed associations between the coronavirus pandemic and increased psychosomatic symptoms and negative emotions. We further found higher risks of increased health complaints in younger people and women. It is also possible that there is higher risk of increased health complaints for respondents with secondary school education, students, and highly spiritual people, but this relationship has to be further investigated. In contrast, respondents with their highest achieved education level being secondary school graduation had a lower risk of increased frequency of stomach-ache. We also found that more negative emotions could increase the frequency of health complaints. Our findings suggest that the coronavirus pandemic and associated government measures could have a significant influence on the prevalence of health complaints and emotional state.
