OBJECTIVE: To evaluate psychometric properties of the Coping Inventory for
Stressful Situations (CISS) in individuals with traumatic brain injury (TBI).
DESIGN: Archival study using Rasch analysis. SETTING: Postacute rehabilitation
hospital. PARTICIPANTS: Adults (N=331) 1 to 15 years after moderate to severe
TBI, recruited consecutively. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: CISS. RESULTS: Indices of unidimensionality and model fit supported the
scale's proposed multidimensional structure consisting of Task, Emotion, and
Avoidant coping style; 3 unidimensional scales showed better fit than a single
combined scale. The 3 scales met Rasch expectations of reliability and separation
for persons and items, as well as adequate response category functioning. The
scales were generally well targeted but showed some evidence of ceiling effect
for Task, and floor effects for Emotion and Avoidant coping; item difficulties
did not fully capture extreme ranges demonstrated by some participants,
suggesting that measurement of coping after TBI on the CISS would be improved
with additional items at low and high ranges of difficulty. Results were
generally equivalent for cross-sectional groups representing short-term (1y),
intermediate (2y), and long-term (5-15y). CONCLUSIONS: The CISS showed good
psychometric properties as a measure of coping style among persons with moderate
to severe TBI in acute and chronic phases of recovery, and showed evidence of
multidimensionality as predicted by theory, consistent with 3 unidimensional
scales. Added items tapping broader (or more accessible, less cognitively
complex) ranges of coping responses would likely benefit the scale overall and
improve correspondence with the response needs of people with TBI.
