The SOC scale is stable over time when applied to women with breast cancer. The longitudinal factor analysis gives support of a stable latent construct in the second-order factor model, allowing for merging all items to one scale reflecting the theoretical construct of SOC. Measurement errors between some items challenge future studies on alternative factor structures.

This study provides evidence of SOC's predictive value for disease progression and BC-caused and all-cause mortality. Sense of coherence provides a complement when designing individual plans that aims to support patients during their treatment.
