Background & Hypothesis

The Executive Function Performance Test (EFPT) is a standardised test of executive function through performance of 4 instrumental activities of daily living. However, daily life tasks are culturally specific, so those in the EFPT lack relevance to Singapore’s context. This study sought to develop an adapted EFPT-Singapore (EFPT-SG) and establish its content validity.

Methods

Thirteen experts were recruited to quantitatively (content validity questionnaire) and qualitatively (focus group) validate the instrument. Service users’ experience and perceptions of task relevance were also gathered from stroke participants (n=8) through semi-structured interviews after an EFPT-SG test administration. Content validity was assessed using the calculation of Content Validity Index (CVI). Qualitative data was analysed using thematic analyses.

Results

Ten of the thirteen questionnaires administered were found complete and analysed. The EFPT-SG demonstrated high content validity with an overall scale- level CVI (S-CVI/average) of .97 and item-level CVI between .94 -1.0. Thematic analysis yielded 4 themes from the focus groups and 3 themes from the stroke informants’ experiences. Overall, it was agreed that the EFPT-SG tasks were culturally relevant and able to assess Executive Functions domains. Opportunities to enhance clinical utility and task relevance of the EFPT-SG were identified from the qualitative feedback gathered.

Discussion & Conclusion

The EFPT-SG is a valid tool for executive functioning evaluation. Further study to establish concurrent and construct validity of the EFPT-SG is ongoing.
