Abstract
OBJECTIVES: to analyze the concept of loneliness in caregivers of people with chronic noncommunicable diseases. METHODS: concept analysis proposed by Walker and Avant. A quantitative scoping review was incorporated to identify the available scientific literature, based on the theoretical framework of the Joanna Briggs Institute. It included 30 articles from the Scopus and PubMed databases, published between 2015 and 2024 in Spanish, English, and Portuguese, with a score greater than or equal to 8/10 according to the Critical Appraisal Skills Programme Español. RESULTS: the background, attributes, and consequences identified in the conceptual analysis of "loneliness" in caregivers allowed us to describe the effects of caregiving on physical, emotional, social, and spiritual well-being. CONCLUSIONS: revealed the complexity and multidimensional trajectory of the phenomenon of loneliness, which allows for the proposal of policies aimed at its prevention and contributes to the well-being of the population.
