This measure assesses perceived loneliness as a subjective experience of closeness or disconnection in interpersonal relationships. The Subjective Experience of Loneliness Scale is intended to capture how individuals experience social and emotional connection, rather than relying solely on objective social contact. It consists of 17 items and typically takes about 3 minutes to complete.
Items ask respondents to rate feelings and perceptions related to social engagement, intimacy, and emotional isolation, supporting a brief appraisal of perceived relational harmony versus strain. In clinical and counseling settings, results from the Subjective Experience of Loneliness Scale may be used to inform case conceptualization and to monitor changes over time alongside other clinical data. The scale is commonly attributed to Daniel Perlman and Letitia Anne Peplau.
