This study examined the role of hope in understanding the link between loneliness and negative affective conditions (viz., anxiety and depressive symptoms) in a sample of 318 adults. As expected, loneliness was found to be a significant predictor of both anxiety and depressive symptoms. Noteworthy, hope was found to significantly augment the prediction of depressive symptoms, even after accounting for loneliness. Furthermore, we found evidence for a significant Loneliness x Hope interaction effect in predicting anxiety. A plot of the interaction confirmed that the association between loneliness and anxiety was weaker among high, compared to low, hope adults. Some implications of the present findings are discussed.
