Results of a nurse-delivered intervention on proficiency and nodule detection with breast self-examination.

PURPOSE/OBJECTIVES: To determine group differences in breast self-examination (BSE) frequency, proficiency, and nodule detection as a result of belief and/or informational interventions.

DESIGN

Prospective, randomized, experimental design using a control group and three intervention groups. Data on outcome measures were collected one year following intervention to determine intervention effect on BSE outcome measures.

SAMPLE

Women without breast cancer ranging in age from 35-88 years.

METHODS

Graduate research assistants conducted in-home interviews and completed intervention delivery and data collection using a standardized protocol for each experimental group. Interventions included counseling about beliefs regarding BSE and informational counseling with BSE demonstration. A second in-home interview was conducted one year after the intervention to determine its effect on BSE outcome measures.

MAIN RESEARCH VARIABLES

Self-recorded frequency, observer-rated proficiency scores, and nodule detection scores.

FINDINGS

The group receiving both the belief and information interventions had significantly higher frequency (t = 2.22, p < or = 0.05) and higher proficiency scores (t = 3.22, p < or = 0.01) for BSE than the control group. The control group had significantly lower rates than the belief/information group for observed proficiency of BSE (t = 7.72, p < or = 0.01) and for nodule detection (t = 8.91, p < or = 0.01).

CONCLUSIONS

The intervention consisting of information, BSE demonstration, and follow-up demonstration significantly increased logged frequency, logged proficiency, observed proficiency, and nodule detection one year postintervention. The group receiving both the belief intervention and information intervention demonstrated the highest nodule detection.

IMPLICATIONS FOR NURSING PRACTICE

BSE teaching should include assessment and discussion about belief toward breast cancer and BSE while providing instruction with return demonstration.
