OBJECTIVE. We investigated the psychometric properties of the Flinn Performance Screening Tool (FPST) for people referred with symptoms of carpal tunnel syndrome (CTS).
METHOD. An occupational therapist collected data from 46 participants who completed the Functional Status Scale (FSS) and FPST after the participants’ nerve conduction velocity study to test convergent and contrasted-group validity.
RESULTS. Seventy-four percent of the participants had abnormal nerve conduction studies. Cronbach’s α coefficients for subscale and total scores of the FPST ranged from .96 to .98. Intrarater reliability for six shared items of the FSS and the FPST was supported by high agreement (71%) and a fair κ statistic (.36). Strong to moderate positive relationships were found between the FSS and FPST scores. Functional status differed significantly among severe, mild, and negative CTS severity groups.
CONCLUSION. The FPST shows adequate psychometric properties as a client-centered screening tool for occupational performance of people referred for symptoms of CTS.
The results of the study provide evidence of the score reliability and construct validity of the FPST for people with CTS symptoms.
As a screening tool, the FPST provides specific detail from a comprehensive menu of occupations that can guide the occupational therapy evaluation, support collaborative goal activities, contribute to a custom therapy program for activity modification, and demonstrate measurable functional outcomes.
In addition, the photographs from the FPST provide advantages that aid cognitive processes, generate client narratives, and save time in the evaluation process (Anzi, 1984; Baum & Edwards, 1993; Berg & LaVesser, 2006; Matheson, 2004).
Occupational therapists should consider using client-centered screening tools that use card sorts to build a personalized profile with the client for function-driven occupational therapy services.
