The Reflective Functioning scale (RF) is a narrative-based assessment of the capacity to coherently conceptualize one's own and others' subjective motivations, emotions, beliefs, and desires. We report the preliminary results of an effort to develop a computerized text analysis version (CRF) of the RF assessment system. A sample of 113 clinical and non-clinical Adult Attachment Interviews (AAI) were utilized to develop the CRF measure. Using the Marker Approach (Mergenthaler & Bucci, 1999), 54 linguistic markers of high RF language were identified. The associations between CRF and RF were significant in both a clinical sample of patients diagnosed with Borderline Personality Disorder (BPD) (Spearman rho=.57, p<.0001) and a non-clinical sample of adults (Spearman rho=.57, p=.002). These results suggest that a CRF rating scale is feasible, has preliminary criterion validity, and, therefore, has potential to facilitate the efficient assessment of RF.
