Abstract
Objectives:
The aim was to evaluate an Acceptance commitment therapy (ACT) intervention for people with knee or hip osteoarthritis; a related aim was to compare treatment effects from Rasch-transformed and standard scales.
Methods:
Participants were recruited from a research database and outpatient rheumatology and orthopaedic clinics at two hospitals. Eligible participants were randomly allocated to either intervention or usual care. Intervention comprised six-sessions of group ACT. Outcomes were assessed two and four months after randomization. Rasch-transformed and standard self-report measures were compared. Qualitative interviews also explored the acceptability of the intervention.
Results:
Of 87 people assessed for eligibility, 31 (36%) were randomized. The main reason for non-randomization was that participants received surgery. Of the 16 participants randomized to intervention, 64% completed ≥50% of the scheduled group sessions. Follow-up data was complete for 84% participants at two months and 68% at four months. Outcome analysis demonstrated important differences between the Rasch-transformed and standard scales. There were significant differences between the groups in pain. Qualitative interviews with seven participants suggested the intervention was acceptable.
Conclusions:
ACT for osteoarthritis is likely to be an acceptable treatment option for people with osteoarthritis. Progress to a definitive trial is warranted. Rasch-transformed outcome scales are preferable in clinical trials where possible.
