Overview
Studies examining the prevalence of mental disorders in cancer [1,2] show that
most cancer patients do not meet the diagnostic criteria for any specific
mental disorder; however, many patients do experience a variety of difficult
emotional responses.[3] To effectively match patient needs and treatment
interventions, health care professionals must be able to distinguish the
periodic difficulties that characterize normal adjustment from more serious
mental disorders.
Psychosocial distress exists on a continuum (see figure below) ranging from normal
adjustment issues through the Diagnostic and Statistical Manual of Mental
Disorders (DSM-IV) Adjustment Disorders;[4] to a level close to, but below, the
threshold (i.e., meets some diagnostic criteria but not all) of diagnosable
mental disorders; to syndromes that meet the full diagnostic criteria for a
mental disorder (e.g., major depressive disorder). This summary focuses
primarily on the less severe end of this continuum: the normal adjustment
issues, psychosocial distress,[5] and the adjustment disorders. (Refer to the
PDQ summaries on Anxiety Disorder, Depression, and Post-Traumatic Stress Disorder for more information.)
