Attachment theory is emerging as an important theoretical foundation in marketing because of the relational nature of consumption, but little guidance exists as to which of many attachment style measures is most suitable for use by researchers. As a result, many measures are being used with little justification, and frequently, these scales are being adapted due to poor measurement fit, length or wording unrelated to the focal attachment figure. This paper aims to evaluate seven existing attachment style measures and provides recommendations regarding which measure is the most suitable for assessing the impact of chronic attachment styles on marketing outcomes.
A literature review identified seven measures of attachment style for analysis. Two studies examine the psychometric properties, susceptibility to response bias and predictive validity of the seven measures (Study 1n = 325 and Study 2n = 205).
Among the seven scales evaluated, the Johnson et al. (2012) [Johnson, Whelan, and Thomson (JWT)] measure exhibited the best psychometric properties and predictive validity for general (i.e. not relationship-specific) attachment styles. In addition, two relationship-specific measures, also with strong psychometric properties, were better able to capture their respective relationships or relationship types than general attachment styles, as expected.
This research provides guidance to researchers on which measure to use when examining the impact of attachment style in marketing.
This research provides marketing researchers guidance on which measure to use when examining the impact of general attachment styles. Because the JWT scale is brief, psychometrically sound and demonstrates strong predictive validity, it can be used for academic and managerial purposes. The authors also confirm previous research suggesting that relationship-specific measures of attachment style may act differently than general interpersonal attachment style measures and vary in their ability to predict marketing outcomes.
This research is the first to provide guidance regarding which measure of attachment style to use in marketing and consumer research. This research can serve as a reference point for future researchers in selecting measures of attachment style and may allow for convergence on a narrow set of measures to advance research in marketing.
