Psychometric properties of the Bengali-Translated Occupational Self-Assessment Short Form

Area of Science:

• Occupational therapy
• Psychometrics
• Cross-cultural adaptation of instruments

Background:

• The Occupational Self-Assessment-Short Form (OSA-SF) is a client-centered tool for goal setting and intervention planning.
• Assessing occupational competence and value is crucial for client-centered occupational therapy.
• A validated Bengali version is needed for use with Bengali adults.

Purpose of the Study:

• To assess the psychometric properties of the Bengali-translated Occupational Self-Assessment-Short Form (BOSA-SF).
• To determine the validity and reliability of the BOSA-SF for Bengali adults.
• To facilitate client-centered goal setting and intervention planning for this population.

Main Methods:

• Translation and cultural adaptation of the OSA-SF into Bengali.
• Administration of the Bengali Occupational Self-Assessment-Short Form (BOSA-SF) to 170 adult participants.
• Confirmatory factor analysis and Rasch analysis to evaluate psychometric properties.

Main Results:

• The Bengali Occupational Self-Assessment-Short Form (BOSA-SF) demonstrated unidimensionality for 11 competence items and 12 value items.
• Both competence and value scales showed local independence.
• Rasch model fitting indicated good validity and reliability for the BOSA-SF.

Conclusions:

• The 11-item Bengali Occupational Self-Assessment-Short Form (BOSA-SF) is a valid and reliable instrument.
• The BOSA-SF can be effectively used for client-centered goal setting and intervention planning with Bengali adults.
• Further research is recommended to explore the BOSA-SF's utility in diverse contexts.
