Perceived partner responsiveness measures have been generally developed without demonstrating construct validity, based on a one-dimensional conceptualization in line with the practical needs of researchers. Based on these limitations, Crasta et al. (2021) have introduced the Perceived Responsiveness and Insensitivity Scale (PRIS) to the literature as an optimized measure with demonstrated validity-reliability. The current study aimed to examine the validity-reliability of the PRIS Turkish form (PRIS-TR) in a sample including individuals with romantic relationships. Participants filled out the research scale set via an online platform. 465 participants with romantic relationships with at least 6 months were randomly divided into two sample groups (n1=336 and n2=129). The mean age of the first sample was 30.07 and of the second sample was 29.54. 75.9% of the first and 81.40% of the second samples included women. Construct validity and internal consistency reliability findings in the first sample confirmed the two-factor structure of PRIS-TR, namely Responsiveness and Insensitivity, and showed that both factors had high reliability. The criterion validity findings revealed that there were significant relationships among Responsiveness, Insensitivity, individual characteristics, and relationship dynamics, in the expected directions in the second sample. Incremental validity findings showed the significant contribution of Insensitivity to relationship dynamics after controlling for Responsiveness in the second sample. Thus, the current research supports that PRIS-TR is a valid-reliable measure.
