Harter's (1985) Self-perception Profile for Children (SPPC) is used to investigate whether the pattern and size of relations among the subscales in a clinic group are equivalent to those in a nonclinic group of children, and whether the items are perceived in the same way and with the same degree of accuracy across both groups. The first aspect indicates equivalence of structure, the latter equivalent measurement. Both are aspects of between-group invariance. It is essential to show evidence of these aspects before content-based comparisons are made between these groups. Using restrictive factor analysis, support was found for equivalence of structure. Equivalence of measurement was partially found. The items were perceived in the same way, but not with the same degree of accuracy. The conclusion is that the SPPC has sufficient between-group invariance to be used in studies with children in a clinic group.
哈特（1985年）的儿童自我认知量表（SPPC）用于调查临床组中各子量表之间关系的模式和大小是否与非临床组儿童的相同，以及两组对这些项目的认知方式是否相同、准确程度是否相同。第一个方面表明结构的等效性，后者表明测量的等效性。两者都是组间不变性的方面。在对这些组进行基于内容的比较之前，必须证明这些方面的证据。使用限制性因素分析，发现了结构等效性的支持证据。部分发现了测量等效性。两组对这些项目的认知方式相同，但准确程度不同。结论是，SPPC具有足够的组间不变性，可用于临床组儿童的研究。
