Morningness-Eveningness Stability Scale improved (MESSi) is a newly constructed measure to assess circadian types and amplitude. In this study, we applied this measure to participants from three different countries: Germany, Spain and Iran. Confirmatory factorial analysis (CFA) of MESSi displayed mediocre fit in the three countries. Comparing increasingly stringent models using multigroup confirmatory factor analyses indicated at least partial measurement invariance (metric invariance) by country for Morning Affect and Distinctness subscales. Age was positively related to Morning Affect (MA), and negatively related to Eveningness (EV) and Distinctness (DI). Men reported higher MA than women, whereas women reported higher DI than men. Regarding country effect, Iranian participants reported highest MA compared to Spaniards and Germans, whereas Germans reported higher DI compared to Iranians and Spaniards. As a conclusion, our study corroborated the validity and reliability of MESSi across three different countries with different geographical and cultural characteristics.

Animal Welfare Attitudes (AWA) are defined as human attitudes towards the welfare of animals in different dimensions and settings. Demographic factors, such as age and gender are associated with AWA. The aim of this study was to assess gender differences among university students in a large convenience sample from twenty-two nations in AWA. A total of 7914 people participated in the study (5155 women, 2711 men, 48 diverse). Participants completed a questionnaire that collected demographic data, typical diet and responses to the Composite Respect for Animals Scale Short version (CRAS-S). In addition, we used a measure of gender empowerment from the Human Development Report. The largest variance in AWA was explained by diet, followed by country and gender. In terms of diet, 6385 participants reported to be omnivores, 296 as pescatarian, 637 ate a vegetarian diet and 434 were vegans (n = 162 without answer). Diet was related with CRAS-S scores; people with a vegan diet scored higher in AWA than omnivores. Women scored significantly higher on AWA than men. Furthermore, gender differences in AWA increased as gender inequality decreased.

Circadian types are related to many physiological, cognitive, and behavioral variables and, therefore, a need for a questionnaire in Farsi language to assess those preferences has emerged. The present study aimed at exploring psychometric properties of the reduced version of the Persian Morningness‐Eveningness Questionnaire (rMEQ). Participants were 268 students recruited from two different universities. Three questionnaires were used to investigate the additional validity data of the Persian version of the rMEQ: Beck Depression Inventory (BDI‐II), Oxford Happiness Questionnaire (OHQ), and General Health Questionnaire (GHQ‐12). The correlations between the rMEQ and the three other questionnaires were −0.45, 0.48, −0.41, respectively. Moreover, the factor analysis of the rMEQ resulted in a single‐factor solution and the Cronbach's α was 0.71. In sum, the Persian rMEQ seemed to be a reliable and valid instrument to differentiate circadian types. We suggest that future studies focus on test‐retest reliability of the rMEQ and an analysis of its unidimensionality with other methods like Item‐Response Theory (IRT).

Background Gestational surrogacy is one of the options for women whom pregnancy is contraindicated. Despite of increasing demand for gestational surrogacy, its various aspects are controversial. The unique nature of surrogacy causes surrogate mothers to face a variety of problems such as, ethical confusion, psychological disturbance and reproductive health matters. Therefore, it is necessary to develop a comprehensive care program for reproductive and sexual health providing specific care at prenatal and pregnancy as well as delivery and postpartum period in socio- cultural context of Iran. Methods This research is an exploratory study with the qualitative-quantitative sequencing design (mixed) that is consisted of three sequential phases. In the first phase, following a qualitative approach, the researcher will explain needs of reproductive and sexual health in surrogate mothers. In the second phase, a primary reproductive and sexual health care program is designed for surrogate mothers in which, in addition to using the qualitative study results, related papers and texts will be also used. In the third phase of the study, reproductive and sexual health care program will be evaluated by RAND method (RAM). Discussion The results of this mixed method study are expected to lead to the development of a reproductive and sexual health care program meeting the needs of surrogate mothers and are in accordance with the cultural conditions of the research community, ultimately leading to improvement in reproductive and sexual health of surrogate mothers.

BACKGROUND:The positive effect of breastfeeding on health is globally accepted. However, breastfeeding has not yet practiced at a favorite level. Empowerment of mothers is an important factor for continuing breastfeeding. This study was conducted to explore women's perception of empowerment in breastfeeding.METHODS:The present qualitative study was conducted in conventional content analysis method. Thirty-four semi-structured deep interviews were conducted with 18 mothers, four key family members, and 12 other personnel involved in breastfeeding counseling services.RESULTS:Analysis of participants’ descriptions led to the emergence of five main categories: Enough knowledge and skill for breastfeeding, feeling adequacy in breastfeeding, overcoming breastfeeding problems, informed belief in the value of breastfeeding, and perceiving comprehensive support for breastfeeding.CONCLUSION:In participants’ point of view, empowerment in breastfeeding can be formed through an acquisition of “Enough knowledge and skill for breastfeeding” as well as assurance about the proper quality and quantity of mother's milk. As well as overcoming breastfeeding problems will lead to stabilization empowerment in breastfeeding. In addition, data analysis showed that informed belief in the value of breastfeeding strengthens the empowerment in breastfeeding and presence of perceived comprehensive support for breastfeeding facilitates empowerment in breastfeeding continuance. Thus, comprehensive plans should be designing for promoting breastfeeding.
