Abstract

Objective

Acceptance and Commitment Therapy for Inpatients (ACT-IN) with psychosis has been found to be efficacious in previous trials, but its effectiveness has not been studied when implemented by frontline clinicians in routine settings.

Method

In this pilot randomized controlled effectiveness trial, inpatients with schizophrenia-spectrum disorders were randomized to ACT-IN plus treatment as usual (TAU) (n = 23) or a time/attention matched (TAM) supportive condition plus TAU (n = 23) delivered by routine hospital staff. Both conditions received individual and group therapy during inpatient care and completed follow-up phone sessions during the first month post-discharge. Patients were assessed through 4 months post-discharge (blinded to condition) to determine feasibility, acceptability, and preliminary effectiveness of ACT-IN.

Results

ACT-IN was feasible to deliver with fidelity by frontline staff when integrated into an acute care setting. At post-treatment, patients reported significantly greater treatment satisfaction in ACT-IN relative to TAM. Overall, results showed significant but similar improvements for both conditions through 4-month follow-up in psychiatric symptoms, functioning, and mindfulness. Only ACT-IN improved over time in distress. Furthermore, patients receiving TAM had a 3.76 times greater risk of rehospitalization over 4 months compared with ACT-IN.

Conclusions

ACT-IN is feasible and acceptable for patients with psychosis, can be implemented by hospital staff when integrated into acute treatment, and may result in decreased rehospitalization compared to alternative therapies. A future full-scale randomized-controlled implementation trial is warranted.
