Abstract
The Therapist Rating Scale (TRS), developed by John L. Vogel in 1961, is a brief, two-item Rating Scale designed to capture a patient’s perception of the quality of the Therapeutic Relationship and their overall satisfaction with their therapist. This instrument was originally conceived as part of a larger research effort investigating the role of Authoritarianism in Psychotherapy, drawing conceptual inspiration from earlier psychometric work by Rogers and Dymond (1954).
The scale is notable for its efficiency, consisting of only two distinct questions. One item assesses the “quality of the relationship” on a nine-point scale ranging from “poor” to “good,” while the second item measures patient satisfaction on a nine-point scale ranging from “strongly dissatisfied” to “extremely satisfied.” The initial subjects for this scale included psychiatric patients receiving treatment at the Psychiatry Clinic of Albert Merritt Billings Hospital and clients utilizing services at the University of Chicago Counseling Center.

Purpose
The primary purpose of the Therapist Rating Scale is to provide a quick and direct assessment of the patient’s subjective experience within the therapeutic context. It is specifically designed to quantify two crucial aspects of the clinical encounter: the patient’s level of satisfaction with the therapist and their perceived quality of the dyadic relationship.
In its original application, the scale served as an outcome measure to determine how personality variables, particularly authoritarian tendencies in the therapist or patient, might influence the perceived success and comfort level of the therapeutic interaction.
Construct
The TRS measures two related, but conceptually distinct, psychological constructs critical to the study of treatment outcomes: Client Attitudes toward Therapists and Satisfaction with Therapist. These constructs are fundamental indicators of treatment engagement and potential efficacy within Psychotherapy research.
By focusing solely on the patient’s self-reported perspective, the scale offers immediate insight into the perceived effectiveness and emotional comfort level experienced in the Therapeutic Relationship, which is widely recognized as a primary predictor of positive therapeutic change.
Validity
Specific psychometric data regarding the validity of the Therapist Rating Scale was not explicitly provided in the primary source documentation by Vogel (1961). The scale’s utility is primarily derived from its face validity and conceptual alignment with established measures of relationship quality, such as those that preceded it (e.g., Rogers & Dymond, 1954).
Given the scale’s brevity and original development within a highly specific research context concerning Authoritarianism, researchers intending to use the TRS for broad clinical assessment should conduct preliminary studies to confirm its construct and criterion validity across diverse populations and treatment modalities.
Reliability
The original publication detailing the development of the Therapist Rating Scale does not indicate specific measures of reliability, such as internal consistency (e.g., Cronbach’s alpha) or test-retest reliability. This absence of data is common for very brief, single-administration research measures from that era.
Due to the instrument’s extremely short, two-item structure, traditional metrics of internal consistency may yield low or misleading results, as the items are intended to capture slightly different facets (quality vs. satisfaction). Researchers utilizing the TRS are strongly advised to conduct their own reliability checks specific to their study population and methodology.
Factor Analysis
No formal factor analysis was reported for the Therapist Rating Scale in the 1961 publication. As the scale contains only two items, standard exploratory or confirmatory factor analysis techniques are generally neither necessary nor statistically feasible.
The items are conceptually designed to capture distinct yet highly correlated facets of the client experience—relationship quality and overall satisfaction—suggesting the possibility of a single underlying factor representing global client appraisal, or a bi-dimensional structure where both components contribute equally to the overall rating of the Therapeutic Relationship.

Permissions & Fee and Test Year
The Therapist Rating Scale (TRS) was first published in 1961. The source documentation indicates that the scale may be used for Research/Teaching purposes without specific restrictions noted in the original publication. Information regarding specific licensing fees or current proprietary status is not detailed, but given its age and academic origin, it is widely utilized for non-commercial research.

Items of the Therapist Rating Scale
IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.
- Does this seem to be a ‘good’ and effective therapeutic relationship?
- How do you estimate the quality of the therapeutic relationship between yourself and this patient?
Note. Items rated on a nine-point scale from “poor” to “good”.
