Research has long shown that the bond between therapist and client is a critical factor in effective therapy, often outweighing the specific therapeutic techniques used. In 1979, Bordin defined this alliance through three key components: goals (shared objectives of therapy), tasks (the agreed-upon methods to achieve those goals), and bond (the mutual trust and emotional connection). The WAI offers a structured way to assess these components, enabling therapists to monitor the health of the therapeutic relationship. By identifying potential issues early, therapists can make timely adjustments to enhance client care. In the following sections, we’ll explore the various versions of the WAI and practical ways to apply them in your practice.

Working Alliance Inventory: Therapist Version

The therapist version of the WAI allows clinicians to assess their perception of the therapeutic relationship. It includes 36 items, with 12 items per subscale (Goals, Tasks, Bond), rated on a 7-point Likert scale from 1 (Never) to 7 (Always).

Sample items include:

“My client and I share confidence in the value of our therapeutic activities.” (Tasks)

“We agree on the priorities for my client’s work in therapy.” (Goals)

“I feel that my client respects me.” (Bond)

This version is valuable for self-reflection, supervision, and research. By comparing their scores with clients’ ratings, therapists can identify discrepancies and adjust their approach. For instance, a therapist noticed resistance in a client during their sixth session. The WAI therapist version showed low goal agreement, prompting a discussion that clarified objectives and boosted the client’s engagement.

Working Alliance Inventory: Short Form (WAI-S)

Developed by Tracey and Kokotovic in 1989, the WAI-Short Form (WAI-S) condenses the original 36-item scale into 12 items, with four items per subscale. It retains the psychometric reliability of the full version while reducing the time needed for administration, making it ideal for busy clinical settings. Using a 7-point Likert scale, the WAI-S provides subscale and total alliance scores. A therapist in a high-volume mental health clinic might use the WAI-S to monitor alliance trends, quickly spotting shifts that signal potential issues, such as a sudden drop in task agreement.

Working Alliance Inventory: Short Revised (WAI-SR)

In 2006, Hatcher and Gillaspy refined the WAI-S into the WAI-SR, keeping the 12-item structure but selecting items based on factor analysis to improve clarity and reduce overlap between subscales. Sample items from the client version include:

“These sessions help me see clearer paths to change.”

“My therapist and I align on what’s important to address.”

“I feel that my therapist values me.”

The WAI-SR’s precision makes it particularly useful when distinguishing between task and goal agreement is critical, such as in trauma therapy where clients may need tailored approaches to achieve shared objectives.

Brief Revised Working Alliance Inventory (BAI)

Introduced by Mallinckrodt and Tekie in 2015, the Brief Alliance Inventory (BAI) reimagines alliance measurement with 16 items split into two subscales: an 8-item Bond subscale and an 8-item combined Tasks/Goals subscale. Developed using Item Response Theory (IRT), the BAI prioritizes measurement accuracy over strict adherence to Bordin’s model.

The BAI uses a 5-point Likert scale for positively worded items (1=seldom to 5=always) and a 4-point scale for negatively worded items to improve response accuracy. Its design ensures consistent performance across diverse populations, making it inclusive and sensitive to subtle alliance changes. Clinicians value the BAI for session-by-session monitoring, as it detects shifts in alliance quality that can guide real-time adjustments.

Unlike earlier WAI versions, the BAI emphasizes psychometric robustness over theoretical alignment, offering a practical alternative for time-constrained settings.

Working Alliance Inventory: Observer Form (WAI-O)

The WAI-O enables third-party observers, such as supervisors or researchers, to evaluate the therapeutic alliance by reviewing recorded or live sessions. It mirrors the original 36-item WAI but rephrases items for an external perspective.

The WAI-O is particularly useful in:

Providing an unbiased view of the alliance.

Assessing clients who may struggle with self-reporting.

Supporting supervision by highlighting alliance dynamics.

For example, in a training clinic, a supervisor might use the WAI-O to review a trainee’s session, noting high task agreement when the therapist clearly explained a mindfulness exercise, which visibly relaxed the client.
