The relevance of Multidimensional perfectionism dimension to interpersonal relationships is quite apparent, in that other-ori-ented perfectionism is viewed as a stable interpersonal tendency to demand perfection from others, and to be extrapunitive and hostile towards others. Research on the interpersonal correlates and consequences of perfectionism is in its initial stages and many issues remain to be investigated. General research has established that perfectionism is associated with the presence of irrational beliefs involving the self and low levels of constructive thinking. Analyses of self-reported relationship behaviors in the present study revealed that neither self-oriented nor other-oriented perfectionism was associated with specific relationship styles in terms of such variables as communication style and responses to conflict. Socially prescribed perfectionism in spouses of pain patients was associated with lows of reported dyadic adjustment. In addition, pain patients married to another-oriented perfectionist tended to report lower dyadic adjustment and less spousal support.
