Objectives:
Therapist competencies when delivering an intervention can impact
clinical outcomes. However, the relationship between competence and
outcome in the context of memory rehabilitation has not previously been
investigated. We aimed to evaluate whether therapist competencies in
delivering a group-based memory rehabilitation intervention, as part of a
randomized-controlled trial, was associated with changes in clinical
outcome in the participants with traumatic brain injury.
Method:
Outcome data on the Everyday Memory Questionnaire (EMQ) and Goal
Attainment Scaling (GAS) were obtained for 24 participants of the memory
rehabilitation trial. Video recordings of intervention sessions
delivered by six therapists were coded using a checklist designed to
evaluate therapist competence in group facilitation.
Results:
Therapists demonstrated consistently high levels of competency in
facilitating the memory group. Correlational analyses showed that there
was a non-significant weak association between EMQ and therapist
competence (r = .28, p = .18), and between GAS and therapist competence for short- and long-term goals (r = −.33, p = .12 and r = −.24, p = .25, respectively).
Conclusions:
We found no significant association between competence and outcome in
this memory rehabilitation trial. This may reflect insufficient
variability in therapist competence and/or the nature of the clinical
outcome measures used. Further research is needed to understand
competence-outcome relationships in cognitive rehabilitation.
