Background: Inconsistencies in the Female Sexual Function Index (FSFI) factor structure and current research and clinical guidelines highlight the need for continued exploration of its psychometric evidence. Furthermore, only one study has assessed its measurement invariance (MI), while the only FSFI psychometric study conducted in Chile lacks quality and representativity. Aim: Therefore, this study aimed to evaluate the psychometric properties of the FSFI (ie, structural and convergent validity, and reliability) in a Chilean sample of women, while also examining MI across relationship status and age groups. Method: A sample of 2595 sexually active adult women (Mage = 32.10, SDage = 10) was derived from a broader Chilean study (Chilean National Sex and Sexuality Study). We used a confirmatory factor analysis to determine its structural validity, sexual satisfaction (SS) dimensions to establish its convergent validity, and Cronbach’s alpha and McDonald’s omega to assess the reliability of its scores. Outcomes: Measures of goodness-of-fit. Results: Confirmatory factor analysis supported a six-factor structure. Internal consistency indices for all FSFI dimensions ranged from good to excellent. MI was achieved across socio-demographic variables at the factor covariance level. Convergent validity indicated modest-to-moderate effects in satisfaction differences based on relationship status. Among other findings, Chilean women in a relationship had significantly higher satisfaction with their sexual communication and compatibility than those who were single, which is consistent with previous findings. Meanwhile, women at risk of experiencing sexual problems scored significantly lower across all SS dimensions than those not at risk. Clinical Implications: This study provides evidence that the FSFI is a valid, reliable, and invariant tool for the clinical practice in the sexual health of Spanish-speaking Latino Americans, especially that of Chilean women’s sexual function (SF) and problems. Strengths & Limitations: This study provided a comprehensive analysis of the FSFI’s psychometric validity evidence, demonstrating its reliability and validity across diverse Chilean women while also offering its first assessment of MI and confirming its suitability for clinical and research use in Spanish-speaking Latino women. Conversely, this study’s main caveat lies in having a predominantly younger, cisgender, and heterosexual sample. Conclusion: Nevertheless, this study’s findings support the FSFI as a valuable research tool for female SF and well-being, particularly within the Chilean population. This study significantly expands the applicability of the FSFI and underscores its MI across sociodemographic factors, as well as its applicability in the Spanish-speaking Latino-American sociodemographic context, particularly the Chilean one.

Background: The International Index of Erectile Function (IIEF) stands out for its utility and widespread use to measure sexual function in men. However, it lacks consistency in its internal latent structure across studies, has not been evaluated for measurement invariance, and has not undergone psychometric validation for its 15-item form in Spanish among South American countries. Aim: To examine the IIEF’s psychometric evidence (ie, structural/criterion validity and reliability) in a sample of adult men and determine its measurement invariance across relationship status (single vs in a relationship) and age generations (generations Z, Y/millennials, and X). Methods: A sample of 650 sexually active males was derived from a broader Chilean study (Chilean Sex and Sexuality Study). We used a confirmatory factor analysis to determine the IIEF’s structural validity, sexual satisfaction dimensions to establish its criterion-related validity, and Cronbach alpha and McDonald omega to assess the reliability of its scores. Outcomes: Measures of goodness of fit. Results: The evidence supported the 5-factor latent solution. Meanwhile, criterion-related validity revealed subtle yet significant differences in sexual satisfaction, with younger men displaying higher satisfaction in various sexual domains. In contrast, middle-aged men and those in a relationship showed better sexual function. Finally, the IIEF was invariant across age groups and relationship status at the factor covariance level. Clinical Translation: This study provides evidence that the IIEF is a valid, reliable, and invariant tool for the clinical practice in men’s sexual health, particularly that associated with their sexual function and dysfunction. Strengths and Limitations: The study included a comprehensive validity analysis of the IIEF’s psychometric properties, demonstrating its reliability and validity across diverse Chilean male subpopulations. The study also offered the IIEF’s first assessment of measurement invariance and confirmed its suitability for clinical and research use in the Chilean population. Meanwhile, the study’s limitations include a lack of clinical population and a sample predominantly younger, cisgender, and heterosexual. Conclusion: Our study provides evidence of the IIEF’s 5-factor structure and measurement invariance across age generations and relationship status in Chilean men, supporting its validity for clinical use and research and broadening its applicability in global sexual health studies, particularly in the Spanish-speaking South American male population.

El Suicidio es un grave problema de salud pública, por lo que evaluar su riesgo es fundamental para su prevención. Si bien existen múltiples factores relacionados, se cuentan con pocos instrumentos psicométricos para la medición conjunta de factores protectores y de riesgo, dificultando una comprensión multidimensional del comportamiento suicida. Sobre esta base, el presente estudio tiene como objetivo desarrollar una propuesta de evaluación multidimensional, de rápida aplicación, que permita evaluar tanto factores de riesgo como protectores. Se utilizó un diseño transversal, de tipo instrumental, junto a un muestreo no probabilístico, por disponibilidad, con dos muestras, de adultos jóvenes mayores de 18 años (n= 405 y n=117). El instrumento final se compone de 25 ítems y 5 dimensiones (i.e. ideación suicida, estrategias de afrontamiento enfocadas en la emoción, autoestima, apoyo social percibido y expectativas hacia el futuro). Los resultados indican buen ajuste del modelo, utilizando ESEM , adecuados niveles de fiabilidad (ω> .8) (α > 0.7). Además, se contó con evidencia de validez basada en la relación con otras variables e invarianza métrica entre hombres y mujeres. Los resultados obtenidos, sugieren que las puntuaciones son fiables y presentan evidencias de validez para su interpretación en población equivalente.

Cervical cancer (CC) remains a critical global health issue which disproportionately affects low- and middle-income countries. In Chile, the Arica and Parinacota region experiences high CC mortality and low Papanicolaou (Pap) test coverage, with indigenous Aymara women facing significant screening barriers. Understanding health beliefs surrounding CC prevention is essential for improving adherence, particularly in under-represented populations. This study assesses the psychometric properties of the CPC-28, an instrument measuring beliefs about CC and Pap testing, among Aymara women in Chile. A cross-sectional survey of 299 Aymara women (25–64) was conducted using stratified probabilistic sampling. Confirmatory factor analysis (CFA) confirmed the CPC-28’s six-factor latent structure, demonstrating strong model fit (CFI = 0.969, TLI = 0.965, RMSEA = 0.058). Reliability indices ranged from acceptable to excellent (α = 0.585–0.921; ω = 0.660–0.923). Moderate correlations emerged between severity, susceptibility, and perceived benefits of Pap testing, although CPC-28 results did not predict adherence. These findings support CPC-28’s validity evidence for Aymara women but highlight cultural influences on screening behaviors. Structural barriers, including language and healthcare inaccessibility, are likely to affect perceived susceptibility. Future research should explore indigenous perspectives and socio-cultural determinants of Pap testing, incorporating mixed-method approaches to identify culturally relevant interventions and improve screening adherence.
