独立功能多维量表（MSIF）是一种评估精神科门诊病人功能障碍的新工具。MSIF与其他残疾评定量表的不同之处在于，它提供了(1)角色责任、(2)存在和支持水平以及(3)表现质量的离散评定。MSIF由半结构化访谈和详细的评分锚组成，在114名精神科门诊患者中进行了验证。该工具具有良好的判据效度、判别效度、解释效度和构念效度。社会适应量表II （SAS II）的可比评分之间的相关性在0.78到0.86之间。然而，使用典型相关的冗余分析表明，尽管两个工具重叠，但MSIF包含SAS II中未包含的信息。此外，在SAS II中，概念上不重叠的子量表只有适度的共同方差。整体和子量表评分的评分间信度（类内相关系数）范围为0.74至1.00。MSIF子量表在外部验证方面的表现如预期的那样，如工作时间、挣得的收入、支持与不支持的就业和住房，以及主流与非主流的教育状况。MSIF总体评分与智商和精神病理学评分有一定的相关性，与文献报道一致。结构效度，使用Cronbach's alpha系数估计，为0.72。MSIF是一种很有前途的新工具，旨在规避现有的纵向研究、干预研究和服务研究的功能结果工具的几个限制。
The Multidimensional Scale of Independent Functioning (MSIF) is a new instrument for rating functional disability in psychiatric outpatients. The MSIF differs from other disability rating scales by providing discrete ratings of (1) role responsibility, (2) presence and level of support, and (3) performance quality. The MSIF, which consists of a semistructured interview and detailed rating anchors, was validated in 114 psychiatric outpatients. The instrument had good criterion, discriminative, interrater, and construct validity. Correlations between comparable ratings on the Social Adjustment Scale II (SAS II) ranged from 0.78 to 0.86. Nevertheless, redundancy analysis using canonical correlation demonstrated that, although the two instruments overlap, the MSIF contains information that is not contained in the SAS II. Furthermore, there was only modest shared variance with conceptually non-overlapping subscales in the SAS II. Interrater reliability (intraclass correlation coefficients) ranged from 0.74 to 1.00 for global and subscale scores. MSIF subscales performed as expected with respect to external validators such as hours of employment, earned income, supported versus nonsupported employment and housing, and mainstream versus nonmainstrearn educational status. MSIF global ratings were modestly correlated with IQ and psychopathology ratings, consistent with reports in the literature. Construct validity, estimated using Cronbach's alpha coefficient, was 0.72. The MSIF is a promising new instrument designed to circumvent several limitations with existing functional outcome instruments for longitudinal studies, intervention research, and services research.
