VHA's Rural category is very large and broadly dispersed; policy makers should supplement analyses of Rural veterans' health care needs with more detailed breakdowns. Most of VHA's Highly Rural enrollees live in the western United States where distances to care are great and alternative delivery systems may be needed.

Two theories of aesthetic preference are reviewed. According to Berlyne's psychobiological theory, the main determinants of aesthetic preference are collative variables such as complexity and novelty, and preference is generally related to its determinants in an inverted-U manner. Recent findings contrary to these predictions are briefly reviewed. According to Martindale's cognitive theory, the main determinant of aesthetic preference is prototypicality or meaningfulness, and preference is usually related to its determinants in a monotonic or U-shaped fashion. Three experiments concerning preference for semantic category exemplars are reported. Typicality accounted for eight or nine times more of explained variance in preference than did long-term novelty, short-term novelty, or mere exposure. Preference was related to both typicality and collative variables by monotonic or If-shaped functions.

This study suggests that there are two distinct types of CAM User that must be considered in future health services research and policy decisions.

The literature on rural veterans' health care needs warrants expansion and investment so that policy makers can make informed decisions in an environment of limited resources and competing interests.
