Abstract
The present study aimed to test the reliability and validity of the Implicit Relational Assessment Procedure (IRAP). The validity of the D_<IRAP> scores was examined as an index of verbal relations, and the response latencies, as an index of psychological flexibility. Undergraduate students (N=32) completed the Anxiety-Implicit Relational Assessment Procedure. To examine the test-retest reliability, 24 of the participants completed the Anxiety-Implicit Relational Assessment Procedure again 1 week after their first participation. To test the validity of the Implicit Relational Assessment Procedure, relations among the Anxiety-Implicit Relational Assessment Procedure, explicit and implicit social anxiety, explicit psychological flexibility, and avoidance behavior were examined. The Dirap scores and response latencies of the Anxiety-Implicit Relational Assessment Procedure revealed good test-retest reliability. Furthermore, the present study provides support for the validity of D_<IRAP> scores as an index of verbal relations, and for moderate validity of response latencies as an index of psychological flexibility.
