Purpose

The WAI evaluates the collaborative relationship between the helper and the client, but does not encompass all aspects of the therapy relationship (i.e. clinical outcomes, recidivism).

Considerations

Scale with potential to be used in any helper/helpee relationship.  There are no standardized measurements for the WAI because the tool measures opinion and self-perception of the relationship.

Internal Consistency

Counseling (Horvath, 1981; n=29, mean age=34.6 (SD=unknown)

  • Excellent:  WAI-client composite - Cronbach alpha = 0.93
  • Excellent:  WAI-therapist composite - Cronbach alpha = 0.87

Online Therapy (Cook & Doyle, 2002)

  • Excellent: WAI-client composite – Cronbach’s alpha=0.86
  • Poor:  WAI-client Task subscale – Cronbach’s alpha = 0.59
  • Adequate: WAI-client Bond subscale – Cronbach’s alpha = 0.70
  • Adequate:  WAI-client Goal subscale – Cronbach’s alpha = 0.76

Criterion Validity (Predictive/Concurrent)

Predictive Validity:

Sex Offenders (DeSorcy, Olver, Wormith, 2017)

  • Poor: When considering the long term outcomes and impact of a working therapeutic alliance, the WAI demonstrated no impact as shown by recidivismp=.368 (no statistical significance between WAI in predicting general recidivism).

Construct Validity

Convergent Validity:

Counseling, Clinical Study (Horvath, 1981)

  • Excellent:  Correlation between Goal-therapist subscale and Task-client subscales was only .01 less than the corresponding validity coefficient (r = .76)

Responsiveness

Online Therapy (Cook & Doyle, 2002)

  • Subscale (task, bond, goal) & composite scores all higher for online therapy compared to face-to-face therapy clients
    • only Goal and Composite were statistically significant
  • WAI-client composite score with online therapy p<0.05
    • t-test = 2.307; p=0.037
  • WAI-client goal subscale score with online therapy p<0.01  
    • t-test = 3.039; p= 0.009

 

Sex Offenders (DeSorcy, Olver, Wormith, 2017)

  • Sample was divided based on PCL-R (Psychopathy Checklist-revised) ratings of <25 or 25+ creating two groups.
  • 颁辞丑别苍’蝉 d showed generally small in magnitude differences between high and low psychopathy groups on WAI score, with the highest (albeit non-significant) difference found on the Bond scale (d = .19), or about one fifth of a standard deviation

Standard Error of Measurement (SEM)

Individuals with Schizophrenia and Schizoaffective Disorder (Gehrs & Goering, 1994; Clients n=22; mean age = 34.3(SD-unknown); Therapists n=12; mean age = 36.7(SD=unknown); mean years working with population = 6.1

  • SEM manually calculated using SEM=SD/(√n)
  • SEM WAI-therapist composite, assessment time 1 (n=22) =5.05
  • SEM WAI-therapist composite, assessment time 2 (n=21) = 5.06

Construct Validity

Construct Validity:

Individuals with Schizophrenia and Schizoaffective Disorder (Gehrs & Goering, 1994)

  • Excellent:  Construct validity between therapist and client scores on the WAI (r=.72 at time 1 and r=.69 at time 2)
  • Adequate-Excellent:  Construct validity between therapist scores on the WAI and Modified Goal Attainment Scale (r=.48 at time 1 and r=.67 at time 2)
  • Adequate:  Construct validity between client scores on the WAI and Modified Goal Attainment Scale (r= .49 at time 2)

Responsiveness

Alcoholism (Connors, DiClemente, Dermen, Kadden, Carroll, Frone, 2000)

  • Outpatient and Aftercare samples
  • Statistically significant relationship (p<0.001, p<0.01, p<0.05) in select categories
    • outpatient sample and WAI-client scores
    • outpatient sample and WAI-therapist scores
    • aftercare sample and WAI-client scores
    • aftercare sample and WAI-therapist scores in select categories
    • Most significant was readiness to change and WAI

 

Alcoholism (Connors, Carroll, DiClemente, Longabaugh, 1997; Outpatient group n=698, outpatient mean age=39.3(10.8), outpatient mean alcohol dependence symptoms=5.7(1.9); Aftercare group n=498, aftercare mean age=42.6(11.0); aftercare mean alcohol dependence symptoms=6.8(1.9)

  • Consistent prediction among outpatient alcoholic clients of treatment participation and positive drinking related outcomes whether from client or therapist perspective
  • WAI positively related to treatment participation & % of days abstinent; negatively related to drinks per drinking day
    • WAI-client: change in R2ranged from .008-.015
    • WAI-therapist: change in R2 ranged from .013-.034
  • WAI-therapist positive predictors of % of days abstinent
