I am using Kendler's 16-item version of the Parental Bonding Instrument (PBI) and need to find and report psychometric properties. Could anybody advise on where I might find its reliability and validity?
The basic resource is Kenneth Kendler's 1996 article "Parenting: A genetic-epidemiological perspective," published in the American Journal of Psychiatry (volume 153, pages 11-20). Cox et al. (2000) replicated Kendler's finding with both the original 25-item version and an 8-item version that is now used by the NCS. This article appeared in Social Psychiatry and Psychiatric Epidemiology, volume 35, pages 353-370. Both the original version and Kendler's abbreviated version have been used in many studies. The very brief (8 item) version first appeared in Comprehsnsive Psychiatry (1992), volume 33, pages 374-377; Klimidis was the first author.
My impression is that most of the studies that have examined the instrument itself have been factor analytic in design. They may not also report basic psychometric data. But they can be cited in support of the instrument's use. And if you turn out to be the first to report actual psychometrics, then your study has an additional value.
For what it may be worth, Klimidis did report psychometrics for the brief form, and his paper is available on ResearchGate. I'm attaching a copy. Good luck with your research program!
