Background: Good psychometrics and cultural relevance are needed for evidence-based practice. Occupational therapy (OT) assessment tools in Bangladesh have been developed outside of Bangladesh and have not been validated or normed for Bangladeshis. This normative and psychometric study was to provide culturally relevant norms for in Bangladesh for bilateral fine motor.
Method: The Functional Fine Dexterity Test (FFDT) consists of two functional/self-care gender-specific task instruments: a shirt with five buttons for males and a pinning board for females. Raters were trained in timing these tasks.
Results: Intra-Class Correlation (ICC) scores were > .85 for all rater teams. Participants were timed three times while they completed the task. Convergent validity was examined using a Pearson’s Product-Moment correlation to compare the average of three trials of the FFDT and three trials of the Nine Hole Peg Test (NHPT). Male and female norms were developed for the FFDT using descriptive statistics. The sample included 180 Bangladesh participants. Convergent validity, when compared to the NHPT, ranged from r = .4 to .67 for males (ages 18-29 and 40-49), p < .05; and r = .53 to .76 for females (aged 18-39), p < .05. FFDT norms were developed for gender and age categories.
Conclusion: The FFDT is a valid test to use for evaluating fine motor dexterity in Bangladesh. This is the first OT instrument to be studied for culturally relevancy.
