Loneliness is among the most common and challenging client problems presented in clinical settings.  Loneliness is often a factor in many other disorders, including depression, one of the most frequently diagnosed conditions in the US. Contemporary research reflects the impact of loneliness and its various forms on social, cognitive, behavioral, physical, and spiritual domains, identifying the experience as a common predictive and mediating factor of other mental and physical disorders.  Nonetheless, clients and practitioners often struggle to identify the significance of loneliness during initial interviews and subsequent sessions.
