The ALP Portuguese version is a psychometrically reliable, valid, and useful measurement instrument for assessing health-promoting lifestyles in adolescence. The ALP is cross-culturally validated and can decisively contribute to a better understanding of adolescent health promotion needs. Additional research is needed to evaluate the instrument's predictive validity, as well as its clinical relevance for practice and research.

Self-efficacy, a social psychology concept, is defined as the likelihood of an individual engaging in health behaviors. Correctly understood, authors posit that health care providers and researchers have an ethical mandate to foster selfefficacy in patients. Further, self-efficacy promotes the commonly ascribed moral principles of respect for the person as a being of worth and fosters autonomy.This paper provides an overview of the concept of self-efficacy, provides a brief discussion on the difference between self-esteem and self-efficacy, and discusses its relationship to health promotion and selected moral principles. Health care providers and researchers are challenged to foster self-efficacy among patients and others as a means to facilitate health promotion.
