Power: The development of the romantic relationship power inventory (RRPI)

In this exploratory research, I developed the Romantic Relationship Power Inventory (RRPI). This research is unique and contributes to the literature because it focuses on validation of a new multi-item, multidimensional power measure that can replace researchers\u27 use of a single question to measure power. Participants (N = 466) completed (a) Romantic Relationship Power Inventory, (b) three single-item questions regarding power, (c) Marlowe-Crowne Desirability Scale (Reynolds, 1982), (d) Investment Model Scale (Rusbult, Martz, & Agnew, 1998), and Relationship Questionnaire (Bartholomew & Horowitz, 1991). A four factor model of the RRPI was tested using a confirmatory factor analysis (CFA). The CFA supported a four-factor model, with internal consistency score coefficients ranging from .83 to .91, thereby supporting hypothesis one. Pearson\u27s Correlation provided partial support for hypothesis two, with (a) convergent validity indicated by significant associations with a single power item, (b) concurrent validity indicated by significant associations with satisfaction and commitment, and (c) discriminant validity supported by low or non-significant associations with social desirability. A MANOVA indicated partial support for hypothesis three. Significant attachment style group differences were found for power process, power outcomes, and total power, with secure attachment being significantly higher on power than the other attachment groups. Implications for practice and research are discussed. This research contributes to the literature by providing a power measure that encompasses various domains of power and has reliable and valid scores
