Spanish Transcultural Adaptation and Validity of the Behavioral Inattention Test.

Objective: To adapt, validate, and translate the Behavioral Inattention Test as an assessment tool for Spanish individuals with unilateral spatial neglect.

Design: A cross-sectional descriptive study.

Setting: University laboratories.

Participants: A sample of 75 Spanish stroke patients and 18 healthy control subjects.

Interventions: Not applicable.

Main Outcome Measures: The Behavioral Inattention Test.

Results: The Spanish version of the Behavioral Inattention Test shows a high degree of reliability both in the complete test ( α = .90) and in the conventional ( α = .93) and behavioral subtests ( α = .75). The concurrent validity between the total conventional and behavioral scores was high ( r = -.80; p < 0.001). Significant differences were found between patients with and without unilateral spatial neglect ( p < 0.001). In the comparison between right and left damaged sides, differences were found in all items, except for article reading ( p = 0.156) and card sorting ( p = 0.117).

Conclusions: This measure is a useful tool for evaluating unilateral spatial neglect as it provides information on everyday problems. The BIT discriminates between stroke patients with and without unilateral spatial neglect. This measure constitutes a reliable tool for the diagnosis, planning, performance, and design of specific treatment programs intended to improve the functionality and quality of life of people with unilateral spatial neglect.
