Relationship Maintenance Scale in Young Couples: Validity Evidence and Reliability of a Short Scale in Peru.

Relationship maintenance has shifted from understudied to extensively researched in the past two decades due to its close association with satisfaction. This study aimed to validate the Relationship Maintenance Scale (EMP) in a sample of young adults in Lima. The sample included 899 participants aged 18-25 (Mean = 20.67, SD = 2.54); 690 females (76.80%) and 209 males (23.20%), all in relationships of at least three months (Mean = 22.05, SD = 19.95). Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to determine the EMP's structure, with Omega coefficient (ω) estimating reliability. Results indicated a four-factor structure for EMP, removing items 8, 9, 12, and 14, demonstrating good fit (SRMR = .043; CFI = .977; TLI = .971; RMSEA = .058). EMP showed acceptable reliability across factors: Companionship (ω = .78), Affectivity (ω = .83), Complementarity (ω = .77), and Shared interaction (ω = .70), with the latter being less stable. EMP correlated as expected with relationship satisfaction (r ≥ .50). In conclusion, EMP is a valid and reliable instrument for future Spanish studies, with further research on psychometric properties recommended.

Development and psychometric properties of the Attitudes Towards Intellectual Disability Scale in the workplace

ABSTRACT Background: A new instrument was designed to measure attitudes towards intellectual disability in the workplace. This tool provides the opportunity to identify underlying cognitive and emotional patterns that may influence people's interaction and performance in such environments. Objective: To construct, validate, and ensure the reliability of a scale measuring attitudes towards intellectual disability, establishing its suitability in labor inclusion programs. Method: A psychometric design was used that incorporated qualitative techniques, such as focus groups and cognitive interviews, in the instrument construction phase. The content validation of the items involved the participation of 15 experts in the field, which resulted in a reduced version with 10 items distributed in two dimensions: Perception and Social Distance. Subsequently, both the validity of the internal structure and the reliability of the instrument were evaluated in a sample of 255 individuals, composed of 35% (n=88) women and 66% (n=167) men. Result: The third-factor model evaluated with confirmatory factor analysis (CFA) was the one that demonstrated excellent fit indices (CFI= .991; TLI=.988; RMSEA= .076; SRMR =.038), with an adequate inter-factor correlation (0.82) and adequate consistency coefficients (α=0.825; ω=0.916). Conclusion: A tool of invaluable value is presented for planning public health programs aimed at reducing stigma and promoting the socio-labor inclusion of people with intellectual disabilities.

RESUMEN Introducción: Se diseñó un nuevo instrumento para medir las actitudes hacia la discapacidad intelectual en el lugar de trabajo. Esta herramienta brinda la oportunidad de identificar patrones cognitivos y emocionales subyacentes que pueden influir en la interacción y el desempeño de las personas en dichos entornos. Objetivo: Construir, validar y asegurar la fiabilidad de una escala que mide las actitudes hacia la discapacidad intelectual, estableciendo su idoneidad en programas de inclusión laboral. Método: Se utilizó un diseño psicométrico que incorporó técnicas cualitativas, como grupos focales y entrevistas cognitivas, en la fase de construcción del instrumento. La validación de contenido de los ítems contó con la participación de 15 expertos en la materia, lo que resultó en una versión reducida con 10 ítems distribuidos en dos dimensiones: Percepción y Distancia Social. Posteriormente, se evaluó tanto la validez de la estructura interna como la confiabilidad del instrumento en una muestra de 255 individuos, compuesta por 35% (n=88) mujeres y 66% (n=167) hombres. Resultados: El tercer modelo factorial evaluado con análisis factorial confirmatorio (AFC) fue el que demostró excelentes índices de ajuste (CFI= .991; TLI=.988; RMSEA= .076; SRMR =.038), con una adecuada correlación interfactorial (0.82). y coeficientes de consistencia adecuados (α=0,825; ω=0,916). Conclusión: Se presenta una herramienta de invaluable valor para la planificación de programas de salud pública dirigidos a reducir el estigma y promover la inclusión sociolaboral de personas con discapacidad intelectual.
