Satisfaction with Sex Life Scale: new psychometric evidence in a portuguese population

Accepted: 19 Oct. 2021 Introduction: In recent years, greater attention has been paid to research on sexual satisfaction because of its association with general well-being and increased interest in sexual and public health issues. Objectives: The objective of this study was to evaluate the psychometric properties of the Satisfaction with Sex Life Scale (SWSLS). Methods: 2,154 Portuguese individuals (M = 34.67 years, SD = 17.18) participated. Confirmatory factor analysis (CFA) and item response theory (IRT) were used. Specifically, the internal structure, reliability and factor invariance of the SWSLS were evaluated by sex and age, as well as the characteristics and performance of the items based on the IRT analysis. Results: The SWSLS Confirmatory Factor Analysis confirmed that a one-dimensional model fit the data well, both for the total sample and for each sex and age group. Furthermore, the SWSLS has adequate reliability for internal consistency. Factor invariance across sex and age was supported by confirmatory multigroup factor analysis. The graduated response model showed a good fit for the one-dimensional model, while the item and test information curves indicated that the SWSLS is more informative to identify high levels of sexual satisfaction. Conclusion: The SWSLS has adequate psychometric properties to measure general sexual satisfaction in the Portuguese population regardless of age and sex

Psychometric network analysis of the Patient Health Questionnaire-4 (PHQ-4) in Paraguayan general population

Background: Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. Objective: This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. Methods: A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. Results: The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they were always replicated within the empirical dimension. The unidimensional structure has shown evidence of configural invariance; therefore, the network structure functioned equally among the different sex groups. Conclusion: The PHQ-4 presented optimal preliminary evidence of validity based on its internal structure, reliability, and invariance between sexes. Therefore, it may be useful as an accurate and brief measure of anxiety and depressive symptoms in the Paraguayan context

Validación de la Escala Breve de Optimismo Interactivo-G en México antes de la COVID-19

The primary objectives of this study were determining the construct, convergent, and discriminant validity of the Brief Interactive Optimism Scale-G (BIOS-G) in participants from six states of Mexico and estimating its internal consistency. In this study 3 289 Mexicans participated (2 028 men and 1 243 women). The average age was = 30.43 years and SD = 10.52. Confirmatory factor analysis (CFA) and multiple regression analysis (MRA) were applied. There were appropriate fit indexes (e. g., CFI = .99; RMSEA = .07.). Convergent validity showed ANR (3 289)=.52(p=<.01;d=medium), with the Satisfaction with Life Scale (SWLS) and the estimation of discriminant validity was r (3 289) r = -.19 with the Brief Scale for Assessing Anger Proneness (APS-G) (p = < .01; d = almost small), Alpha = .70 (3 289); p = < .01; omega = .76. The conclusion is that there is partial national evidence supporting the use of BIOS-G, because Mexico lacks a measure of this kind, being useful, at least, for research purposes.Los objetivos primarios del presente estudio fueron determinar la validez de constructo, convergente y discriminante de la Escala Breve de Optimismo Interactivo-G (EBOI-G), en participantes de seis estados de México y calcular su consistencia interna. Participaron 3289 mexicanos, 2028 hombres y 1243 mujeres (18 casos no contestaron cuál era su género). Su edad promedio = 30.43 años, de = 10.52. Se usó el análisis factorial confirmatorio y análisis de regresión múltiple, y se encontraron buenos indicadores promedio de bondad de ajuste (e. g., CFI = .99; RMSEA = .07.). Se evaluó la validez convergente, r (3 289) = .52 (p = < .01; d = mediano), con la Escala de Satisfacción con la Vida. Se estimó la validez discriminante, r (3 289) r = -.19, con la Escala Breve de Disposición a la IRA (p = < .01; d = casi pequeño). El alfa = .70 (3 289); p = < .01; el omega = .76. Se concluye que hay evidencia parcial nacional que apoya el uso de la EBOI-G, debido a la carencia de una medida de este tipo en México, útil cuando menos para propósitos de investigación.Os objetivos primários do estudo foram determinar a validade convergente e discriminante do construto da Escala Breve de Otimismo Interativo-G (EBOI-G), em participantes de seis estados do México e calcular sua consistência interna.

The construct, convergent and divergent validity, and reliability of three optimism scales among North American university students

ABSTRACT The primary objective of this study is to compare the construct, convergent and divergent validity and the reliability of three optimism scales. The study relied on a nonprobability sample of 100 social work students at Western Michigan University in the United States (Seventy-nine percent of the sample were female, and 21% were male). The sample’s mean age was 26.35 years, SD = 7.70. Sixty-nine percent (69%) of the respondents self-identified as White, and 31% self-identified as African American, Hispanic/Latino, multiethnic, Native American or Asian American. The study used confirmatory factor and multiple regression analyses (CFA and MRA). The findings show that the Life Orientation Test-Revised (LOT-R) and the Personal Optimism Scale (POS) were supported by three indicators of goodness of fit, while the Brief Interactive Optimism Scale-Garcia (BIOS-G) was supported by eight. The LOT-R showed no acceptable internal consistency indicators, but the POS and the BIOS-G showed several good internal consistency indicators. Correlations of all of these scales with the Physical Well-being Scale-Garcia (PWS-G) ranged from r (100) = .303, p = .002 to r (100) = .439, p = .000. The three scales had divergent validity because their scores did not differ by gender (LOT-R: t(100) = −.885, p = .383; POS: t(100) = −.263, p = .794; BIOS-G: t(100) = −.840, p = .407). The findings suggest the advisability of recommending the BIOS-G, which is short and easy to use and understand

Relationship Between Fear of Monkeypox and Intention to be Vaccinated Against Monkeypox in a Peruvian Sample. The Mediating Role of Conspiracy Beliefs About Monkeypox

The present study evaluated the predictive capacity of fear of Monkeypox (MPX) on the intention to be vaccinated against MPX and the influence of conspiracy beliefs as a mediating variable in this relationship in 516 Peruvian sample with an average age of 27.10 years participated. Monkeypox Fear Scale, MPX Conspiracy Beliefs Scale and a single item of intention to be vaccinated against MPX were used. Statistical analyses have included estimation of descriptive statistics for all variables in the model tested and Structural Equation Modeling to predict intention to be vaccinated against monkeypox. It has been found that fear has a positive impact on conspiracy beliefs about MPX and intention to be vaccinated against MPX. Finally, conspiracy beliefs are negatively related to intention to be vaccinated. As for indirect effects, both are statistically significant. The model explains 11.4% of the variance in beliefs and 19.1% in intention to be vaccinated. It is concluded that fear of MPX played an important role, both directly and indirectly, in the intention to be vaccinated against MPX, having conspiratorial beliefs about MPX as a mediating variable. The results have important implications for public health practices aimed at combating doubts about MPX vaccination
