Number panic attacks, past 12 months


PANICYRNO is a 3-digit-numeric variable.

0: Not in Universe
997: Unknown-refused
998: Unknown-not ascertained
999: Unknown-don't know


For sample adults age 18+ who had a panic attack in the past 12 months that did not occur in a life-threatening situation (PANICYR, PANICTHREAT, PANICNOTHRET), PANICYRNO reports responses to the question, "About how many attacks did you have in the past 12 months?"

PANICYRNO was part of a series of mental health questions taken from the Composite International Diagnostic Interview - Short Form (CIDI-SF) screening scale for panic attack.


According to the Field Representative's Manual for 1999, this set of questions on panic attacks was included "to determine if the Sample Adult has attacks when they suddenly feel frightened, anxious, or very uneasy; whether they occurred in a life-threatening situation; how many attacks in the past year and when was the most recent one; did they happen when the Sample Adult was not in danger or the center of attention; and what other physical reactions occurred when they were having these attacks."

Although PANICYRNO was not used in calculating panic attack scores, other panic attack questions taken from the CIDI-SF screening scale can be used to calculate the likelihood that a respondent met the diagnostic criteria for this mental disorder (i.e., probability of psychiatric caseness).


For more information on the CIDI-SF screening scale for panic attack and for instructions on how to calculate panic attack scores, see PANICYR.


This variable only occurs in 1999.
