Brief Summary

This trial studies how well a text-based intervention works in improving adherence to hormone therapy in patients with stage I-III hormone receptor positive breast cancer. Women often require long term therapy with adjuvant hormone therapy to prevent the cancer from returning and to improve overall survival. Side effects from hormone therapy may prevent some women from staying adherent to their medication therapy. A text-based intervention may provide educational information to breast cancer patients who are undergoing adjuvant hormone therapy.

Detailed Description

PRIMARY OBJECTIVES:

I. Examine the efficacy of messaging for adjuvant hormone therapy compliance promotion (mAHT-CaP) in a randomized control trial (RCT) design.

SECONDARY OBJECTIVES:

I. Conduct mediator analyses of intervention efficacy..

EXPLORATORY OBJECTIVES:

I. Explore whether age (=\< 45 versus \[vs.\] \> 45 at diagnosis) and race/ethnicity (white vs. non-white) moderate intervention effects on medication adherence and symptom distress.

OUTLINE:

PHASE I: Participants attend focus groups on adherence to hormone therapy.

PHASE II: Participants are randomized to 1 of 2 groups.

GROUP I: Participants receive text messages twice weekly for 6 months to remind and motivate participants about adjuvant hormonal therapy (AHT) adherence.

GROUP II: Participants receive usual care.

After completion of study, participants are followed up at 3, 6, and 12 months.

Primary Outcome Measures
NameTimeMethod
Adjuvant hormone therapy (AHT) adherenceUp to 12 months

Assessed by wireless smart pill bottles for all participants. Daily adherence will be defined as accessing the pill bottle once per 24 hour period. Proportion adherence will be summarized by week and study arm, and presented graphically.

Symptom distressUp to 12 months

Measured by the Breast Cancer Prevention Trial Symptom Scale, which has sound psychometric properties in breast cancer (BCa) patients. There are a total of 43 items in the scale across eight domains. Each item is a five-point Likert scale, ranging from 0 (not at all) to 4 (extremely), used to rate symptoms. Items accounting for side effects specifically related to AHT (e.g., bone pain) and other general symptoms (e.g., constipation) are added. Participants are asked whether they are bothered by each symptom and whether they think it related to their AHT or not. The two resulting scales consist of the sum of the endorsed symptom total each woman does or does not attribute to AHT.

Secondary Outcome Measures
NameTimeMethod
Cognitive-affective barriers for AHT adherenceUp to 12 months

Will be developed and will test the mediating effect of cognitive affective barriers on proportion of days adherent (average over 12 months)

Cognitive-affective barriers for symptom distressUp to 12 months

Will be developed and will test the mediating effect of cognitive affective barriers on the difference between baseline and 12-month symptom distress. Symptom distress is measured by the Breast Cancer Prevention Trial Symptom Scale
