Reliability and validity study of Turkish version of Adolescent/Adult Sensory Profile

Introduction: The evaluation and treatment of sensory processing disorders are significant fields of interest for occupational therapy. The Adolescent/Adult Sensory Profile (AASP) questionnaire is used for sensory evaluation of adults to measure sensory experiences, including auditory, visual, taste/smell, touch, movement, and activity level. The aim of the study was to study the reliability and validity of the Turkish version of the AASP. Method: The AASP Turkish version was administered to 450 healthy individuals aged 11 years and over and 40 schizophrenia patients aged 18-64 years. Results: There were no critical problems encountered during translation. The clarity of the questionnaire was increased by making minor changes in conjunctions and adjectives in the Turkish adaptation. The AASP showed high internal consistency and test-retest reliability (r = 0.66-0.82 and r = 0.67-0.82, respectively). There was a statistically significant difference between the healthy individuals and schizophrenia patients for low registration, sensory seeking, and sensory sensitivity (p < 0.05). According to the factor analysis, four factors with 20 items under low registration, 16 items under sensory avoiding, 12 items under sensory seeking, and 12 items under the sensory sensitivity quadrant were defined. Conclusions: The Turkish version of the AASP questionnaire is a reliable and a valid questionnaire for the Turkish population.
