Reliability and Validity of the Arabic Version of the Short Form Supportive Care Needs Survey Questionnaire (SCNS-SF34-A)

Abstract

Objective

This study aimed to assess the psychometric properties of the Arabic version of the Supportive Care Needs Survey Short Form 34 (SCNS-SF34-A) among heterogonous group of cancer patients.

Method

This was a multicenter, prospective, descriptive-correlational survey that included 297 cancer patients recruited from two hospitals. The tool construct validity, internal consistency, and test-retest reliability were evaluated.

Results

The participants comprised 60.6% females, with ages ranging from 18 to 82 years. The majority were married (71.7%) and had mainly breast cancer (28.3%). Exploratory factor analysis supported a four-factor structure that are: health system information and patient support domain, psychological domain, physical and daily living domain, and sexuality domain. This tool explained 64.2% of the variance. The SCNS-SF34-A demonstrated excellent internal consistency for the whole scale (Cronbach's alpha = 0.954) and high test-retest reliability (ICC = 0.954) for the subscales (Cronbach's alpha ranged from 0.82 to 0.95 and ICC ranged from 0.950 to 0.960.

Conclusion

SCNS-SF34-A exhibits robust psychometric properties and holds promise for enhancing cancer care in the Arab world, contributing to a more tailored and effective approach to addressing patients' supportive care needs. The four-factor structure aligns with international studies, emphasizing the nuanced nature of variations. Further validation in diverse Arabic-speaking populations and the exploration of additional forms of validity are recommended.

Implications for Nursing Practice

The SCNS-SF34-A presents a reliable, culturally adapted, and sensitive assessment tool for the diverse supportive care needs of cancer patients in Oman and the Arab world. It contributes to the improvement of the quality of cancer care and patient-centered approach in clinical practice.
