Outcome Measures

Primary Outcomes (2)

  • Program Feasibility

    Feasibility will be demonstrated by enrollment (\>50% of eligible and approached patients will enroll), retention (\>70% of enrolled participants will complete the two intervention sessions) and attendance (≥70% of participants completing at least one session).

    Up to 3 months

  • Program Acceptability

    Acceptability will be demonstrated by \>75% of participants reporting average satisfaction scores greater than the mid-point of the Client Satisfaction Questionnaire. The total score range is 3-12, with higher scores indicating a better outcome.

    Up to 3 months

Secondary Outcomes (1)

  • Adjuvant Endocrine Therapy (AET) Initiation

    Up to 3 months

Study Arms (1)

Culturally Aware Adjuvant Endocrine Therapy (AET) Non-Initiation Intervention

EXPERIMENTAL

Participants will have two (2), 60 minute, individual sessions with a nurse practitioner via videoconferencing (in person or via telephone) and complete three (3) questionnaires at the time of enrollment, 1-month post-baseline, and 3-months post-baseline.

Behavioral: Culturally Aware Adjuvant Endocrine Therapy (AET) Non-Initiation Intervention

Interventions

One-to-One virtual (videoconference) behavioral intervention.

Limitations and Caveats

As a single-arm pilot study, we lacked a comparator group to assess INITIATE in comparison to the standard of care or an attention-matched control. The sample size was modest, which limited our ability to evaluate clinically meaningful differences in psychosocial outcomes over the study period. Further, participants mostly had Stage 1 breast cancer, and the study was conducted at an academic medical center; thus, the findings may not be generalizable to all patients with breast cancer.
