    Background: Loneliness among older adults is a significant public health problem that requires early detection for effective intervention. The ALONE scale is a brief (five items) and reliable tool that holds promise for clinical use.Objective: Translation, cultural adaptation, content validity, and face validity of the ALONE scale for Portuguese community-dwelling older adults (≥ 65 years). Methodology: This methodological study comprised three stages: (a) translation and cultural adapta-tion; (b) content validity assessment with 15 experts (content validity index, CVI); and (c) face validity assessment through semi-structured interviews with eight older adults.Results: Linguistic equivalence was achieved with the original ALONE scale. The items had strong content validity (CVI ≥ 0.8, average CVI of 0.97, universal agreement of 0.71, excellent kappa). Face validity assessment showed that the ALONE scale captures the feelings of loneliness, is useful, and is easy to understand and complete. Conclusion: The translated and culturally adapted ALONE scale shows content and face validity for assessing loneliness among Portuguese older adults in community settings.

    Objectives: Severe loneliness poses a significant risk to older adults’ health and quality of life. Thisstudy assessed the psychometric properties (reliability and validity) of the Portuguese version of theALONE scale in community-dwelling older adults and explored the scale’s associations with sociode-mographic, social isolation, depression, life satisfaction, and daily functioning.Method: A descriptive, correlational study was conducted with 285 Portuguese older adults. Thequestionnaire included sociodemographic and health data, the ALONE scale, Social Isolation Scale(SIS), Satisfaction with Life Scale (SWLS), Geriatric Depression Scale (GDS-15), UCLA Loneliness Scale(UCLA-16), and Lawton and Brody IADL Scale. Analyses included confirmatory factor analysis, internalconsistency, group comparisons, correlations, and logistic regression.Results: The confirmatory factor analysis supported a unidimensional model with satisfactory fitindices and internal consistency (α = 0.743). Severe loneliness correlated positively with social isolationand depression and negatively with life satisfaction and daily functioning. Participants experiencingsevere loneliness were likely older, female, living alone, socially isolated, depressed, and dependentin daily activities. Significant predictors included social isolation (OR = 0.806) and depression (OR =1.131).Conclusion: The ALONE scale demonstrated validity and reliability for assessing loneliness in olderadults, making it a suitable, efficient tool for clinical practice.
