| Sumario: | Objective:Adherence to adjuvant endocrine therapy (AET) in breast cancersurvivors is suboptimal. Using the theory of planned behavior (TPB), this study aimedto identify the strongest predictors from theTPB of AET intentions and past behaviorand assessed whether ambivalence and anticipatory emotions increased thepredictive capacity of TPB.Methods:Two hundred eighty women diagnosed with hormone positive (HR+)breast cancer who filled at least one prescription of AET responded to a surveymeasuring TPB constructs, attitudinal ambivalence, and anticipatory emotions. Theoutcomes were intentions to adhere to AET and past medication adherence (previous2 weeks).Results:TheTPB explained 66% of intentions to adhere to AET (P< 0.001). Ambiva-lence did not improve theTPB model's predictive value. When emotions were includedwithTPB, the model explained 70% of adherence intentionsF11,226= 52.84,P< 0.001(R2c= .70). This increase of 4% in predictability was statistically significant (ΔR2= 0.04),F6, 226= 7.90,P< 0.001. Women who self‐reported nonadherence in the past 2 weeksdiffered significantly in theTPB variables, ambivalence, and anticipatory emotions fromadherent women. Nonadherent participants reported lower‐future intentions toadhereF1, 236= 5.63,P= 0.018.Conclusions:Results suggest key concepts, such as anticipatory positive emotionsthat should be addressed in future interventions to enhance AET adherenceand survivorship |
