ABSTRACT
Resumen Objetivo: El presente estudio de tipo instrumental tuvo como objetivo diseñar y validar una escala cuya finalidad es evaluar la percepción de las personas frente a las cuatro dimensiones de la infidelidad-sexual, emocional, cognitiva y virtual-, a través de dos subdimensiones de la cognición -motivos y consecuencias- Método: Para ello se realizó una tabla de especificaciones y se construyeron los ítems, los cuales fueron sometidos a validación por jueces. Se realizó el ajuste a la escala y esta fue aplicada a una muestra voluntaria de 301 participantes con edades entre los 18 y 70 años ( = 29.84; DE = 14.07), y que además contaran con habilidades cognitivas básicas de comprensión lectora. Resultados: Tras realizar el análisis factorial exploratorio, se encontraron siete factores que explican el 48,64 % de la varianza total acumulada, y el índice de extracción permitió la conservación de todos los ítems, modelo factorial confirmado, con adecuados niveles de bondad de ajuste (CFI = .910; RMSEA = .049). Además de ello, con el Alfa de Cronbach general de .84 se evidenció una alta confiabilidad de la escala y con un coeficiente de dos mitades de Guttman de .87 se encontró una fuerte relación entre dos mitades. Conclusión: la Escala de Evaluación Cognitiva de Infidelidad es un instrumento pionero que permite evaluar con criterios de validez y confiabilidad el fenómeno de la infidelidad.
Abstract Objective: The purpose of this instrumental study was to design and validate a scale that assesses people's perception regarding the four infidelity dimensions-sexual, emotional, cognitive, and virtual- through two cognition sub-dimensions: reasons and consequences. Method: To do this, a specifications table was made, and the items were built, which were subjected to judges' validation. The scale was adjusted and implemented for a voluntary sample of 301 participants, aged 18-70 ( = 29.84, DE = 14.07), who had basic reading comprehension cognitive skills. Results: After the exploratory factor analysis, seven factors were found that explained 48.64% of the total cumulative variance, and the extraction rate allowed all items to remain and confirmed factorial model, with adequate goodness of fit levels of adjustment (CFI = 0.910, RMSEA = 0.049). In addition, the general Cronbach Alpha of 0.84 showed a high reliability of the scale, and with a coefficient of two Guttman halves of .87, a strong relationship was found between the two halves. Conclusion: The Cognitive Infidelity Assessment Scale is a pioneering tool that allows the evaluation of the infidelity phenomenon with valid and reliable criteria.
ABSTRACT
In the current study, we reasoned that when pregnant, women should be especially motivated to protect their reproductive investments as well as their pair bond and be vigilant about intrasexual competitors. To investigate this, pregnant women ( n = 66) and nonpregnant women ( n = 59; age M = 27.41, SD = 3.36) in committed relationships read a jealousy-evoking scenario that was accompanied by a picture of either an attractive or an unattractive woman, after which they indicated their jealousy about such a situation. Moreover, we asked whether a mate's emotional infidelity would evoke more jealousy than his sexual infidelity. The results showed that for pregnant women, both rivals evoked similar amounts of jealousy, whereas nonpregnant women's jealousy was mainly evoked by the attractive rival. Moreover, pregnant women indicated they would be most upset by their partner's emotional infidelity, and especially if they were previously exposed to the attractive rival. Nonpregnant women considered both types of infidelity equally upsetting. These results emphasize the adaptive function of jealousy and extend the literature on the influence of a rival's attractiveness on women's jealousy by focusing on the experiences of pregnant women.
