Self-administered Acupressure for Persistent Cancer-related Fatigue: Fidelity Considerations.

contextComplementary therapies are frequently used by breast cancer patients for symptom management; however, documentation of the components of intervention fidelity for studies is not widely available.

objectiveThis report examines the components of intervention fidelity, as put forth by the Treatment Fidelity Workgroup of the Behavior Change Consortium at the National Institutes for Health (NIH-BCC Workgroup), within an ongoing acupressure study of breast cancer survivors with persistent cancer-related fatigue (PCRF).

designFor the acupressure study, the research team designed a randomized, controlled trial (RCT) with 3 parallel groups: (1) stimulating acupressure (intervention group); (2) relaxing acupressure (intervention group); and (3) standard care (control group).

settingAt baseline and at wk 3 and wk 6 of the study, women in the acupressure study attended sessions for training and data collection at clinics in the counties of Michigan where they lived. The self-administration of acupressure occurred in participants' homes.

participantsTargeted enrollment for the acupressure study is 300 breast cancer survivors who had experienced moderate-to-severe PCRF lasting longer than 1 y beyond treatment. The women are being recruited from 5 counties in Michigan, using the Michigan Tumor Registry to identify potential participants. The subsample report includes 183 participants who have completed all 10 wk of the acupressure study. Most participants in the acupressure study are Caucasian, are married, and have some college education.

interventionThe acupressure study's educators teach participants in the intervention groups to self-administer either relaxing or stimulating acupressure for a 30-min period on a daily basis for 6 wk. All 3 groups receive the usual care for breast cancer survivors. OUTCOME MEASURES: For the acupressure study, the participants log the frequency of the self-administered acupressure sessions and their fatigue levels. Symptom assessments are made for all groups by telephone in the acupressure study at wk 2 through wk 5 to assess fatigue. A competency checklist is used at each session of training and retraining of both acupressure educators and participants. For this report, the 5 recommended fidelity components for interventions are (1) dose, (2) training, (3) intervention delivery, (4) intervention receipt, and (5) enactment of the intervention.

resultsThe ongoing RCT incorporated all 5 components of fidelity and can serve as a model for future work in this area.

conclusionsResearch protocols that address intervention fidelity can provide results that support internal and external validity. Clinicians should consider recommending complementary interventions that have incorporated fidelity components into their efficacy testing.
