Despite the wide use of the Short-Form Supportive Care Needs Survey Questionnaire (SCNS-SF34), the measurement invariance of the SCNS-SF34 across the main groups-gender and age-which might be of interest in the application of the instrument has never been confirmed. To provide an accurate assessment tool to evaluate the unmet needs of Chinese cancer patients, the present study aimed to assess the measurement invariance of the SCNS-SF34 across gender and age groups and to assess the validity and reliability of the Chinese version of the SCNS-SF34.
The SCNS-SF34 was administrated to 1106 Chinese cancer patients. Other instruments included the Memorial Symptom Assessment Scale-Short Form (MSAS-SF), the Short-Form-12 Health Survey version 2 (SF-12 v2) and the Hospital Anxiety and Depression Scale (HADS). Factor structure, internal construct validity, convergent validity, known-group validity and internal consistency were assessed.
Our data fit the original five-factor model. Multi-group confirmatory factor analysis indicated measurement invariance across age and gender groups. The domains of the SCNS-SF34 had moderate correlations with the corresponding domains of the MSAS-SF, the SF-12 v2 and the HADS, which supported convergent validity. Of the 34 items, 33 had an item-total correlation that was corrected for an overlap of > 0.4 to support the internal construct validity. The SCNS-SF34 aptly differentiated patients by age and gender. The Cronbach's alpha coefficient ranged from 0.64 to 0.87.
We confirm the measurement invariance of the Chinese version of the SCNS-SF34 across gender and age group. It is a valid and reliable tool for evaluating the needs of Chinese patients with cancer.
尽管短式支持性护理需求调查问卷（SCNS-SF34）被广泛应用，但该问卷在主要群体（性别和年龄）中的测量不变性尚未得到确认，而这种不变性可能在该工具的应用中具有重要意义。为了提供一种准确的评估工具来评估中国癌症患者的未满足需求，本研究旨在评估 SCNS-SF34 在性别和年龄组之间的测量不变性，并评估 SCNS-SF34 中文版的有效性和可靠性。
1106 名中国癌症患者接受了 SCNS-SF34 调查。其他评估工具包括记忆症状评估量表-短式（MSAS-SF）、健康调查简表 12 项版本 2（SF-12 v2）和医院焦虑抑郁量表（HADS）。评估了量表的结构因素、内部结构有效性、收敛有效性、已知组有效性和内部一致性。
我们的数据拟合了原始的五因素模型。多组验证性因子分析表明，该量表在年龄和性别组之间具有测量不变性。SCNS-SF34 的各维度与 MSAS-SF、SF-12 v2 和 HADS 的相应维度具有中等相关性，支持了收敛有效性。34 个条目中，有 33 个条目的条目总分相关性在 0.4 以上，支持内部结构有效性。SCNS-SF34 能够恰当地根据年龄和性别区分患者。克朗巴赫 α 系数范围为 0.64 至 0.87。
我们确认了 SCNS-SF34 中文版在性别和年龄组之间的测量不变性。它是一种评估中国癌症患者需求的有效、可靠的工具。
