Intervention fidelity monitoring of Urban Zen Integrative Therapy (UZIT) for persons with pulmonary hypertension

Background: Systematic and consistent dose delivery is critical in intervention research. Few studies testing complementary health approach (CHA) interventions describe intervention fidelity monitoring (IFM) and measurement. Objective: To describe methodological processes in establishing and measuring consistent dose, delivery, and duration of a multi-component CHA intervention. Methods: Adults with pulmonary hypertension received six weekly, 1-hour Urban Zen Integrative Therapy (UZIT) sessions. A total of 78 sessions were delivered and 33% of these sessions were audited. Intervention dose (time allocated to each component), intervention consistency (protocol adherence audits), and intervention delivery (performance and sequence of components) were captured using remote video observation and review of the recorded video. IFM audits were performed at the beginning (n = 16), middle (n = 5), and end (n = 5) of the study. Results: UZIT interventionists adhered to the intervention protocol (99.3%) throughout the study period. Interventionists delivered UZIT components within the prescribed timeframe: 1) Beginning: gentle body movement (18.9 ± 5.8 min.), restorative pose with guided body awareness meditation (21.3 ± 2.7 min.), and Reiki (22.8 ± 3.1 min.); 2) Middle: gentle body movement (15.9 ± 1.5 min.), pose/body awareness meditation (30.1 ± 6.5 min.), and Reiki (30.1 ± 7.0 min.); 3) End: gentle body movement (18.1 ± 3.6 min.), pose/body awareness meditation (35.3 ± 6.4 min.), and Reiki (34.5 ± 7.0 min.). Essential oil inhalation was delivered during UZIT sessions 100% of the time. Interventionists adhered to treatment delivery behaviors throughout the study period: beginning (98.86%), middle (100%), and end (100%). Discussion: In this pilot study, we demonstrated that the dose, consistency, and delivery of multi-component CHA therapy can be standardized and monitored to ensure intervention fidelity.
