dc.description.abstractAgeing is a life-span complex process. In current cohorts, the final years of life are often marked by increased cognitive, functional, and relational decline due to a range of socioeconomic, biological, and personal factors. As a result, individuals are more susceptible to social isolation and loneliness. The emergence of the COVID-19 pandemic has further intensified the need to assess feelings of loneliness and to develop appropriate interventions. Given the strong association between loneliness and both physical and psychological health and well-being, this area has become a research priority. The aim of this study is to adapt the De Jong Gierveld Loneliness Scale for the Portuguese population and to gather evidence of its validity and reliability. A study was conducted with 191 participants aged between 54 and 99 years old. Results from the exploratory factor analysis revealed a two-factor structure (social and emotional), with Cronbach's alpha values ranging from 0.719 to 0.734. Confirmatory factor analysis indicated good model fit (CFI = 0.996, GFI = 0.931, RMSEA = 0.093) and satisfactory reliability (0.73–0.76). In conclusion, the instrument demonstrates sound psychometric properties and represents a suitable tool for researchers and practitioners. However, further studies with more representative samples of the Portuguese population are recommended.eng
