Development and Validity Evidence of the Myths of Romantic Love Multidimensional Scale (MRL-MS) in Young Chileans

Romantic love myths refer to culturally shared beliefs about love, falling in love and relationships. Their study and evaluation are of utmost importance, given that they have been recognized as a risk factor in dating violence with serious implications for the well-being and mental health of young people. The aim of the present study was therefore to develop a scale to evaluate beliefs about romantic love, establishing evidence of reliability and validity for the interpretation of the scores obtained. An instrumental cross-sectional design was carried out, applying the Multidimensional Romantic Love Myths Scale (MRL-MS) to a sample of 1001 Chilean young people between 18 and 25 years of age. As a result, a scale composed of 40 items assessing 8 interrelated dimensions was obtained, with evidence of validity based on internal structure, adequate levels of reliability, and evidence of metric and scalar invariance between sexes. Finally, the limitations of the study are discussed and possible applications and guidelines for future research are proposed.

Los mitos del amor romántico refieren a creencias culturalmente compartidas sobre el amor, el enamoramiento y las relaciones de pareja. Su estudio y evaluación son de suma importancia, dado que se han reconocido como un factor de riesgo en la violencia en el noviazgo con graves implicancia en el bienestar y salud mental de los jóvenes. Por tanto, el objetivo del presente estudio es desarrollar una escala que permita evaluar las creencias sobre el amor romántico, estableciendo evidencias de fiabilidad y validez para la interpretación de las puntuaciones obtenidas. Se llevó a cabo un diseño transversal de tipo instrumental, aplicando la Escala Multidimensional Mitos del Amor Romántico (MRL-MS) a una muestra de 1001 jóvenes chilenos entre 18 y 25 años. Como resultado, se obtuvo una escala compuesta por 40 ítems que evalúan 8 dimensiones interrelacionadas, con evidencia de validez basada en la estructura interna, adecuados niveles de fiabilidad, y evidencias de invarianza métrica y escalar entre sexos. Finalmente, se discuten las limitaciones del estudio y se proponen posibles aplicaciones y directrices para futuras investigaciones.

Naive skepticism scale: development and validation tests applied to the chilean population

Abstract Background Skepticism has traditionally been associated with critical thinking. However, philosophy has proposed a particular type of skepticism, termed naive skepticism, which may increase susceptibility to misinformation, especially when contrasting information from official sources. While some scales propose to measure skepticism, they are scarce and only measure specific topics; thus, new instruments are needed to assess this construct. Objective This study aimed to develop a scale to measure naive skepticism in the adult population. Method The study involved 446 individuals from the adult population. Subjects were randomly selected for either the pilot study (phase 2; n = 126) or the validity-testing study (phase 3; n = 320). Parallel analyses and exploratory structural equation modelling were conducted to assess the internal structure of the test. Scale reliability was estimated using Cronbach's alpha and McDonald's omega coefficients Finally, a multigroup confirmatory factor analysis was performed to assess invariance, and a Set- Exploratory Structural Equation Modeling was applied to estimate evidence of validity based on associations with other variables. Results The naive skepticism scale provided adequate levels of reliability (ω > 0.8), evidence of validity based on the internal structure of the test (CFI = 0.966; TLI = 0.951; RMSEA = 0.079), gender invariance, and a moderate inverse effect on attitudes towards COVID-19 vaccines. Conclusions The newly developed naive skepticism scale showed acceptable psychometric properties in an adult population, thus enabling the assessment of naive skepticism in similar demographics. This paper discusses the implications for the theoretical construct and possible limitations of the scale.

Construction and validation of a scale of stigma against individuals diagnosed with schizophrenia

Antecedents: Individuals diagnosed with schizophrenia are not just dealing with their diagnoses. They are facing stigma due to their pathology. International research has proposed that individuals diagnosed with schizophrenia suffer more stigma than other types of mental issues. However, in Chile, a valid scale is not available to measure stigma against individuals diagnosed with schizophrenia. Objectives: To fill this gap, this research is aimed to develop and validate a scale to measure stigma against individuals diagnosed with schizophrenia. Methods: Two stages were completed to achieve the research objective. First, a pool of items was developed based on the three critical components of stigma, cognitive, affective and behavioral. Three independent judges were asked to assess the content aspects of the content validity of the items. Second, following an instrumental and longitudinal design with non-probabilistic with a quota sampling by gender (N = 607) the validity and reliability of the final scale was assessed. Results: A one-dimensional scale composed of 22 items showed good statistical boundaries. The observed factor loadings suggest that the items adequately represent the dimension (λ>, 6), and the reliability estimates are optimal (α>, 8; ω>, 8). Results suggest that the scale can be used the respondents' gender irrespectively.

Antecedentes: Las personas diagnosticadas con esquizofrenia no solo enfrentan su diagnóstico. Ellos también tienen que enfrentar el estigma producto de su patología. Investigaciones internacionales han propuesto que las personas diagnosticas con esquizofrenia sufren más de estigma que otras patologías mentales. Sin embargo, en Chile no existe una escala validada para medir el estigma hacia personas diagnosticadas con esquizofrenia. Objetivos: Para cubrir esta necesidad en la literatura, esta investigación tiene como objetivo desarrollar y validar un instrumento para medir el estigma hacia personas diagnosticadas con esquizofrenia. Métodos: Dos etapas fueron completadas para lograr el objetivo de investigación. En primer lugar, se desarrolló un set de ítems basados en los "tres componentes centrales del estigma: creencia, emoción y conducta". Se les solicitó a tres jueces independientes evaluar estas preguntas de acuerdo con su contenido y validez. En segundo lugar, siguiendo un diseño instrumental y longitudinal con muestreo no probabilístico por cuotas por género (N = 607) se evaluó la validez y confiabilidad de la escala final. Resultados: Una escala unidimensional compuesta por 22 ítems mostró buenos límites estadísticos. Las saturaciones de factores observadas sugieren que los ítems representan adecuadamente la dimensión (λ>, 6), y las estimaciones de confiabilidad son óptimas (α>, 8; ω>, 8). Los resultados sugieren que la escala se puede utilizar independientemente del género de los encuestados

Desarrollo y evidencia de validez de una escala multidimensional de riesgo de suicidio y factores protectores en un contexto chileno / Development and evidence of validity of a multidimensional scale of suicide risk and protective factors in a Chilean context

Resumen: 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.

Abstract: Suicide is a major public health concern, making risk assessment essential for its prevention. Although there are multiple related factors, there are few psychometric tools for the joint measurement of both protective and risk factors, making a multidimensional understanding of suicidal behaviour difficult. On this basis, the present study aims to develop a quickly applicable, multidimensional assessment approach to evaluate both risk and protective factors. A cross-sectional, instrumental design was used, together with a non-probabilistic, availability sampling, with two samples of young adults over 18 years of age (n=405 and n=117). The final measure is composed by 25 items and 5 dimensions (i.e. suicidal ideation, emotion-focused coping strategies, self-esteem, perceived social support and expectations towards the future). Results show good model fit, using ESEM, adequate levels of reliability (ω> .8) (α > 0.7). In addition, there was evidence of validity based on the relationship with other variables and metric invariance between men and women. Results suggest that the scores are reliable and present evidence of validity for their interpretation in equivalent populations.

Análisis Psicométrico de la Escala Orientación hacia la Dominancia Social (SDO) Mediante un Modelo de Ecuaciones Estructurales Exploratorias (ESEM) / Psychometric Analysis of the Social Dominance Orientation (SDO) Scale Through a Model of Exploratory Structural Equations (ESEM)

Resumen El objetivo de la presente investigación es analizar las propiedades psicométricas de la Escala Orientación hacia la Dominancia Social (SDO), en una muestra no universitaria de la ciudad de Arica, Chile, implementando técnicas psicométricas de acuerdo con el estado del arte disciplinar. El muestreo fue no probabilístico, por conveniencia y disponibilidad de 812 participantes, entre edades de 18 a 89 años. Se realizaron estimaciones de fiabilidad, análisis factoriales confirmatorios y modelos de ecuaciones estructurales exploratorios, contrastando diferentes modelos. Los resultados proporcionaron evidencia de validez basada en la estructura interna de la prueba, presentando buen ajuste de la estructura de la SDO (RMSEA=.076; CFI=.963; TLI=.956), y adecuados niveles estimados de fiabilidad (Oposición a la Igualdad: α=.85, ω=.84; Dominancia Grupal: α =.67, ω =.66). Finalmente, se concluye que las puntuaciones de la escala SDO poseen evidencia suficiente para sustentar su uso e interpretación, en población no universitaria equivalente a la del presente estudio.

Abstract The objective of this research is to analyze the psychometric properties of the Social Dominance Orientation (SDO) Scale in a non-university sample of the city of Arica, Chile, implementing psychometric techniques according to the state of disciplinary art. The sampling was non-probabilistic due to the convenience and availability of 812 participants in a range of ages from 18 to 89 years. To contrast different models were performed reliability estimates, confirmatory factorial analyses, and exploratory structural equation models. The results provided evidence of validity based on the internal structure of the test, presenting good adjustment of the SDO structure (RMSEA=.076; CFI=.963; TLI=.956), and estimated adequate levels of reliability (Opposition to the Equality: α=.85, ω=.84, Group dominance: α =.67, ω =.66). Finally, the research concluded that the scores of the SDO scale have sufficient evidence to support its use and interpretation, in a non-university population equivalent to that of the present study.

Development and validity evidence of the Two-Dimensional Sexual Sensation Seeking Scale / Desarrollo y evidencia de validez de la Escala Bidimensional de Búsqueda de Sensaciones Sexuales

Abstract Sexually transmitted infections (STIs), mainly HIV/AIDS, are acquired through risky sexual behaviors that have been associated with sexual sensation seeking. The purpose of this work is development a new scale for the assessment of sexual sensations seeking, with evidence of validity based on internal structure and relationship to other measures, for use in young people and adults in a Latin American context. An instrumental study was performed, with time-space sampling of students from the two Chilean cities with the highest rates of HIV. Final scale has 9 items to evaluate two dimensions: (1) sexual emotions seeking and (2) tendency to sexual boredom. The identified structure provides good levels of reliability and presents validity evidence, based on the internal structure of the test, using CFA and ESEM. Two-dimensional sexual sensation seeking scale evidence proper psychometric properties to evaluate the seeking for sexual sensations in equivalents samples.

Development and validity evidence of the multidimensional scale of sexual selfconcept in a Spanish-speaking context

Abstract Background/objective: STIs and HIV/AIDS are an important public health problem, transmitted by risky sex behaviours. In this context, it is necessary to identify protective factors, of those behaviours, as sexual self-concept. Sexual self-concept is a multidimensional trait (i.e. sexual self-esteem; sexual self-efficacy; and sexual assertiveness), but, in an extensive review, we did not find any measure to assess this multidimensional construct in a Spanish-speaking context. The objective of this research is development a scale to assess sexual self-concept in young people and adults. Method: Time-space sampling with a total size of 792 participants, coming from the two Chilean cities (i.e. Arica and Iquique) with the highest HIV rates, aged between 17 and 53 years old (ME = 23.42; SD = 6.33), with 66.2% women (N = 500), 33.6% men (N = 258). Results: Final scale has 16 items and 4 dimensions: sexual self-esteem, sexual self-efficacy, assertive sexual communication, and assertive sexual behaviour. The identified structure provides satisfactory levels of reliability (ω > .8) and presents robust evidence of validity, based on the internal structure of the test, using ESEM (RMSEA = .060; CFI = .99; TLI = .98), evidence of validity based on relationship to other variables (i.e. risky sexual behaviour) and measurement invariance between men and women. Conclusions: The multidimensional scale of sexual self-concept has adequate psychometric properties to assess sexual selfconcept in equivalent samples.
