Modified Q16 neurotoxic symptoms Questionnaire

Abstract

<em><strong>Objective</strong><em> To modify the neurotoxic symptoms questionnaire (Q16) and assess its repeatability and comparability. <em><strong>Materials and Methods</strong><em> A group of 100 participants ranging from the ages of 18 to 40, with an education level equivalent to high school or technical college, similar to the education level of dry-cleaners in Bogotá was used to validate the questionnaire in sydney, Australia. Three test questionnaires and a demographic information questionnaire were presented to participants. The modified Q16 was applied twice in order to evaluate repeatability. <em><strong>Results</strong><em> sixty males and forty females participated in the study. Cronbach’s Alpha was applied in order to analyze the reliability of the Q16 modified with a Likert scale, getting an internal consistency of 0.887. The paired t test was applied in order to evaluate repeatability, obtaining significant differences in two questions with p=0.027 and p=0.020 values, respectively. Comparing the results of the Likert scale scores with the original, a direct link was observed between them. <em><strong>Conclusions</strong><em> The modified Q16 provides more answer choices, closer to reality, internal consistency and repeatability. The modified Q16 may be a better option to assess neurological symptoms
