Manualization of Occupational Therapy Interventions: Illustrations from the Pressure Ulcer Prevention Research Program

Am J Occup Ther, 2011 · DOI: · Published: November 1, 2011

Simple Explanation

Manualization of a complex occupational therapy intervention is crucial for ensuring treatment fidelity in both clinical and research settings. It is essential for assuring trustworthiness and replicability of randomized controlled trials (RCT’s). Treatment manuals provide structure for an intervention’s delivery, enable consistent delivery by different therapists, facilitate staff training, and allow treatment replication in different contexts. The optimal solution may be to create manuals that, although structured, allow for individualization and for responsiveness to ever changing life circumstances and narratively described patient experiences.

Study Duration

Seven years

Participants

20 adults with SCI and a history of recurring pressure ulcers

Evidence Level

Not specified

Key Findings

1
Manualized interventions are associated with better treatment outcomes, especially when they are flexible and when the content is easily translated into action.
2
The PUPP feasibility study suggested that the intervention was viable and potentially helpful in preventing pressure ulcers and that principles of Lifestyle Redesign® were readily translatable into individualized treatment.
3
The second version of the LR-PUPP manual allows for individualization and flexibility within the context of an overarching structure, explicit guiding principles, and theoretical models.

Research Summary

Manualization of a complex occupational therapy intervention is a crucial step in ensuring treatment fidelity for both clinical application and research purposes. Intervention manuals linked to RCTs offer several advantages including the promotion of evidence-based practice, the enhancement of treatment integrity, the facilitation of staff training and quality assurance, and the potential for treatment replication The current emphasis on evidence-based practice, in conjunction with the requirements of RCTs, creates the need for manualized interventions as part of the process of establishing intervention fidelity.

Practical Implications

Enhanced Treatment Fidelity

Manualization ensures the intervention is delivered as intended, promoting consistent and reliable outcomes.

Improved Staff Training

Manuals facilitate effective training programs, ensuring therapists understand and can implement the intervention effectively.

Facilitated Research Replication

Detailed manuals allow for replication of the intervention in different contexts, strengthening the evidence base for occupational therapy practices.

Study Limitations

1
Manuals may contain a single approach to intervention, which downplays the eclectic and improvisational nature of clinical practice.
2
Manuals tend to reduce the opportunities for independent clinical judgment and can emphasize therapeutic technique and structure over process.
3
The use of manuals has also been reported to negatively affect the fluidity of intervention delivery and hence the quality of the interpersonal relationship between the patient and the intervener
