Content Specificity of Interpretation Bias Related to Social and Emotional Loneliness in Emerging Adulthood

According to cognitive theories, loneliness is associated with biased cognitive processes. However, studies investigating interpretation bias (IB) related to feelings of loneliness are scarce. The current study aimed to investigate (a) whether emotional loneliness (perceived absence of intimacy) and social loneliness (perceived absence of satisfying connections) are associated with a negative IB while controlling for related psychosocial symptoms, and (b) whether these two types of loneliness show content-specific IB. Sample 1 included an unselected university sample (N = 138, 81.9% female, M = 20.8 years, SD = 4.4), and Sample 2 utilized a preselected university sample with elevated anxiety/depression levels (N = 315, 69.5% female, M = 23.8 years, SD = 4.3). Participants completed questionnaires on emotional and social loneliness, social isolation, social anxiety, depression, hostility, and an ambiguous scenarios task measuring IB. The results showed that emotional and social loneliness were uniquely associated with a negative IB related to the unavailability of social network. Social loneliness was additionally positively related to an IB for rejection and negatively to an IB for hostility in Sample 2. These results provide evidence for a content-specific negative IB in both types of loneliness. Future studies are needed to replicate these findings as it could aid in developing an effective treatment program for loneliness targeting underlying cognitions in young adults.
