Spanish version of the Generalized Sense of Power Scale /Versión española de la Escala de Sensación de Poder General

The Spanish adaptation of the relationship power inventory

Power dynamics are fundamental when negotiating conflicts. However, no instrument for measuring power in romantic relationships has been adequately adapted to Spanish culture. The goal of this research was to adapt the Relationship Power Inventory (RPI; Farrell et al., 2015) to Spanish culture and language, filling this gap by providing a rigorous instrument for evaluating this construct. Study 1 was conducted to obtain evidence based on Spanish adaptation of RPI content. Once the Spanish adaptation of the RPI was built and we obtained validity evidence based on the test content, in Study 2, the scale was administered to two different samples of the adult population following a cross-validation approach. Specifically, in Sample 1 (N = 400), the training sample, a statistical analysis and an exploration of the dimensional structure and reliability of the measure were carried out. In Sample 2 (N = 755), the validation sample, the internal structure of the scale was confirmed, and evidence of external validity and generalization was obtained. The exploratory and confirmatory factor analysis showed a good fit for the four-factor structure. These dimensions were invariant to gender and had adequate validity based on their relationship with other variables (dependence on the partner, conflict-resolution strategies, and psychological well-being). In sum, the Spanish version of the RPI (SARPI) is a reliable instrument with sufficient valid evidence to provide accurate measurement of power differences in the context of romantic relationships.

Elucidating the Effect of Perceived Power on Destructive Responses during Romantic Conflicts

Prior research has indicated that the people one loves the most, such as their romantic partners, ironically, are also the people toward whom they often direct destructive behaviors in times of conflict, and such destructive responses become one of the most challenging relationship problems. Identifying the conditions that promote destructive (vs. constructive) conflict-resolution strategies is a crucial gap requiring study to help individuals build healthier and happier relationships. Across three studies (total N = 728), we examined whether (a) power is related to direct destructive (vs. constructive) responses during romantic conflicts; (b) this effect was moderated by the seriousness of the conflict and the relationship's inclusiveness. In Study 1, participants involved in romantic relationships completed scales assessing interpersonal power, the conflict's seriousness, their relationship's inclusiveness, and conflict-resolution responses. In Studies 2-3, the participants were randomly assigned to complete an essay in which the conflict's seriousness and power were experimentally manipulated. Findings from hierarchical regression analyses consistently showed that power led to destructive (and lower constructive) responses. However, this only occurred when the participants faced severe conflicts and their partner was not central to their self-concept. An internal meta-analysis of the studies confirmed the reliability and significance of these relationships; |r's| =.13-37. Together, these results support the proposition that power asymmetries can threaten relationships by driving destructive responses during romantic conflicts, and untangle the conditions under which this happens. The conflict's seriousness and the inclusiveness of the relationship may be considered to provide skills that help individuals navigate their relationships' life challenges.
