Construct Validity of a Measure of Affective Communication in Psychotherapy.

Overview
abstract
The present study evaluates the psychometric properties of a therapist measure for evaluating the affective communication created between the patient and therapist during the initial stages of treatment. The Affective Communication Questionnaire (ACQ) was administered to a sample of 81 therapists, each rating a single patient, and principal component analysis indicated the measure has coherent dimensions with strong internal consistency. The construct validity of the ACQ was then established in a sample of 16 therapists rating 73 patients diagnosed with Borderline Personality Disorder (BPD). The measure was found to have a strong relationship to the related constructs of transference, countertransference, and affect experience in predicted directions. The measure also was found to have a modest relationship to independent assessments of patient functioning; most notably more negative affect was significantly related to more odd/eccentric (cluster A) and less anxious/fearful (cluster C) personality disorder symptoms, and greater narrative coherence. Differences in affective communication as a function of treatment type were also evaluated. The clinical and research implications of the findings are discussed.
