Measuring religious social capital: scale properties of the modified Williams Religious Social Capital Index among Friends of cathedrals

This article evaluates a new version of the Williams Religious Social Capital Index (WRSCI), for use within Friends' associations of Church of England cathedrals. Like the WRSCI, the modified measure (WRSCIM) takes into consideration four distinct elements: trust, and bonding, bridging and linking social capital. As part of a larger project, 923 Friends from six cathedrals responded to the 12 items concerning religious social capital. The modified index achieved satisfactory levels of internal consistency reliability; and construct validity was supported by a clear relationship between Friends' activity and levels of religious social capital. However, in contrast to the demands on cathedral congregants (among whom the original WRSCI was developed), there is no expectation that cathedral Friends will have regular face-to-face contact with fellow members; so, a measure of social networks in the association would complement the WRSCIM to provide a more complete picture of Friends' religious social capital.
