Thai version of the Inventory of Interpersonal Problems (IIP)  ฉบับ 32 ข้อ ( IIP-32)

IIP-32__Thai version

Horowitz et al developed the Inventory of Interpersonal Problems (IIP) in 1988, based on the proposal of an interpersonal behaviour concept known as ‘interpersonal circumplex’ by Leary, Benjamin and Wiggins, in which interpersonal behaviours are arranged in a circular fashion, creating intersections on two axes – the control axis (domineering-submissive) and affiliation axis (hostile-friendly). The two axes create eight octants of the interpersonal circumplex, starting with ‘domineering’ on the top, and moving counter-clockwise as follows: domineering/controlling, vindictive, cold, socially avoidant, non-assertive, overly accommodating, self sacrificing and intrusive, in which the related characteristics in adjacent octants were positively correlated while the negatively correlated octants were found opposite.

We gratefully received permission to translate the IIP into Thai from Professor Leonard Horowitz in 2017.

Len Horowitz passed away on November 11, 2019, at the age of 82, in Portola Valley, California. We extended our condolences to friends in the psychotherapy society, expressing that as Buddhists, we dedicated all the merits we had collected to him, wishing him a serene and happy existence.
