Psychometric and clinical assessment of the Persian-SCREENIVF among infertile couples.

There is a significant rate of infertility and subsequent psychological problems among couples worldwide. Screening and treatment of the emotional burden of infertility and related Assistant Reproductive Therapies help to improve the quality of life of infertile people. Specific instruments which measure infertility-related status are more accurate. This study aimed to validate the SCREENIVF questionnaire to be used for the psychological screening and care of couples who seek infertility treatment. This quantitative psychometric study was run in infertility private and governmental clinics in XXX on 344 infertile women and men. They filled Persian-SCREENIVF. The Rasch-Andrich rating scale model was applied to investigate the psychometric quality of the survey. Additionally, structural equation modelling was run for model fit and construct validity as well. Moreover, multivariate analysis of variance (MANOVA) was applied to examine the effects of demographic variables on the extracted constructs of the instrument in the population of the study. The results revealed five constructs in the questions with the corresponding items. Overall, the demographic variables have no contribution to these five constructs. Persian-SCREENIVF can be used for further studies about emotional disturbances in infertility problems.

The dynamics of a duopoly Stackelberg game with marginal costs among heterogeneous players.

One of the famous economic models in game theory is the duopoly Stackelberg model, in which a leader and a follower firm manufacture a single product in the market. Their goal is to obtain the maximum profit while competing with each other. The desired dynamics for a firm in a market is the convergence to its Nash equilibrium, but the dynamics of real-world markets are not always steady and can result in unpredictable market changes that exhibit chaotic behaviors. On the other hand, to approach reality more, the two firms in the market can be considered heterogeneous. The leader firm is bounded rationale, and the follower firm is adaptable. Modifying the cost function that affects the firms' profit by adding the marginal cost term is another step toward reality. We propose a Stackelberg model with heterogeneous players and marginal costs, which exhibits chaotic behavior. This model's equilibrium points, including the Nash equilibrium, are calculated by the backward induction method, and their stability analyses are obtained. The influence of changing each model parameter on the consequent dynamics is investigated through one-dimensional and two-dimensional bifurcation diagrams, Lyapunov exponents spectra, and Kaplan-Yorke dimension. Eventually, using a combination of state feedback and parameter adjustment methods, the chaotic solutions of the model are successfully tamed, and the model converges to its Nash equilibrium.

Comparison Between the Effect of the Information-Motivation-Behavioral (IMB) Model and Psychoeducational Counseling on Sexual Satisfaction and Contraception Method Used Under the Coercion of the Spouse in Iranian Women: A Randomized, Clinical Trial / Comparação entre o efeito do modelo Informação-Motivação-Comportamental (IMB) e o aconselhamento psicoeducacional sobre a satisfação sexual e o método contraceptivo usado sob coerção do cônjuge em mulheres iranianas: um ensaio clínico randomizado

Abstract Objective Women play an essential role in maintaining the family's health, and family planning is part of women's and families' health. The couple's mutual understanding of family planning methods is essential in selecting contraception. Acceptance of and satisfaction with different contraception methods can impact sexual satisfaction. The present study aimed to compare the effect of the information-motivation-behavioral (IMB) model and psychoeducational counseling on sexual satisfaction and contraception methods of women referring to health centers in Kerman. Methods This trial was conducted on 81 women aged 18 to 45, in Kerman health centers, from 2021 to 2022. Participants were randomly divided into 3 groups of 27 people (control, psychoeducational counseling, and IMB method). Three online counseling sessions were held for the psychoeducational group, and four were held for the IMB group. The control group received routine care. The IBM SPSS Statistics for Windows, version 22 (IBM Corp. Armonk, NY, USA) was used for data analysis using nonparametric Friedman and Kruskal-Wallis tests. Results The mean age of participants was 32.59 ± 7.04, and the majority of them had university degrees and were homemakers. The mean sexual satisfaction score significantly increased immediately after the intervention and 1 month later in the 2 interventional groups (p< 0.0). Changes in contraception methods after intervention were significant in the psychoeducational group (p= 0.0) Conclusion The results indicate the positive impact of psychological counseling on women's sexual satisfaction and contraception method. The IMB method also impacted men's sexual satisfaction but did not lead to any changes in the contraceptive method.

Resumo Objetivo A mulher desempenha um papel essencial na manutenção da saúde da família, e o planejamento familiar faz parte da saúde da mulher e da família. A compreensão mútua do casal sobre os métodos de planejamento familiar é essencial na seleção da contracepção. A aceitação e a satisfação com os diferentes métodos contraceptivos podem afetar a satisfação sexual. O presente estudo teve como objetivo comparar o efeito do modelo informação-motivação-comportamental (IMB) e aconselhamento psicoeducacional sobre a satisfação sexual e métodos contraceptivos de mulheres encaminhadas para centros de saúde em Kerman. Métodos Este estudo foi realizado em 81 mulheres de 18 a 45 anos, nos centros de saúde de Kerman, de 2021 a 2022. As participantes foram divididas aleatoriamente em 3 grupos de 27 pessoas (controle, aconselhamento psicoeducacional e método IMB). Foram realizadas três sessões de aconselhamento online para o grupo psicoeducativo e quatro para o grupo IMB. O grupo de controle recebeu cuidados de rotina. OIBM SPSS Statistics for Windows, versão 22 (IBM Corp. Armonk, NY, EUA) foi utilizado para a análise dos dados por meio dos testes não paramétricos de Friedman e Kruskal-Wallis. Resultados A média de idade das participantes foi de 32,59 ± 7,04, sendo que a maioria delas possuía nível superior e eram donas de casa. A pontuação média de satisfação sexual aumentou significativamente imediatamente após a intervenção e 1 mês depois nos 2 grupos de intervenção (p <0,0). As mudanças nos métodos contraceptivos após a intervenção foram significativas no grupo psicoeducativo (p = 0,0) Conclusão Os resultados indicam o impacto positivo do acompanhamento psicológico na satisfação sexual das mulheres e no método contraceptivo. O método IMB também impactou a satisfação sexual dos homens, mas não levou a nenhuma mudança no método contraceptivo.

RESULTS: The Malay version and its adaptation for a new cultural context are described. CONCLUSION: The Malay version achieved the aims of the original version and its conceptual and operational equivalence. It may be used as the first Malay instrument to measure anxiety among children in research and in clinical and community settings.
