Convergence in patient and therapist alliance ratings early in treatment with Personality Assessment Inventory clinical scales and subscales

We examined discrepancies in 81 patient-therapist dyads' alliance ratings early in treatment (3rd or 4th session) in relation to Personality Assessment Inventory clinical scales, subscales and global psychopathology. Results indicated that PAI global psychopathology (mean clinical elevation) and the scales of Aggression [AGG], Somatization [SOM], and Anxiety-Related Disorders [ARD] were significantly, negatively associated with an absolute difference of patient and therapist alliance ratings at Session 3. Higher initial scores on these clinical scales at treatment onset are associated with less difference (i.e., more convergence) in patient/ therapist ratings of alliance at Session 3. Correlations between PAI clinical subscales and absolute differences of patient and therapist alliance ratings at Session 3 also demonstrated statistically significant inverse relationships for several PAI subscales of Aggression- Attitude [AGG-A], Aggression-Physical [AGG-P], Somatic- Health Concerns [SOM-H], Anxiety-Related Disorders-Traumatic Stress [ARD-T], Anxiety-Related Disorders- Obsessive Compulsive [ARD-O], Borderline Features-Affective Instability [BOR-A], Borderline- Self-Harm [BOR-S], Anxiety-Physiological [ANX-P], Depression-Physiological [DEP-P] and Antisocial-Stimulus Seeking [ANT-S]. Again, higher scores on these subscales at treatment onset are associated with less difference (i.e., more convergence) in patient/therapist ratings. We also examined group differences between patients rating alliance higher (Group 1) and therapists rating alliance higher (Group 2) and found that Group 1 had significantly lower scores on Mania-Activity Level [MAN-A]. Clinical implications of results are discussed.
