Assessment

Assessment and diagnosis of delayed sleep phase disorder (DSPD)

Similar clinical assessment is required of all circadian rhythm sleep disorders.  Prior to a diagnosis of DSPD, patients presenting with a complaint of delayed sleep need to be differentiated from those with other sleep-onset problems (to rule out anxiety, stress, or restless legs syndrome).1
DSPS, occurring most common in adolescents, can negatively affect school performance.2
