The Self-Image Scale is a self-report measure originally developed for use in women with cancer. Two subscales assess appearance satisfaction (self-acceptance) and perceptions of partners' acceptance of their appearance (partner-acceptance). This study aimed to increase the Self-Image Scale's utility by 1) confirming the two-factor structure of the German version of the Self-Image Scale, 2) testing measurement invariance across sex and age groups and validity, and 3) gathering general population normative data.
Confirmatory factor analysis methods were used to examine the proposed two-factor model in a random sample of adults from the general German population (N = 1367). Measurement invariance, scale reliability, and validity were assessed.
The original factor structure and measurement invariance across sexes and age groups were supported. Women showed significantly lower self-acceptance than men. Adolescent and young adult women showed higher self-acceptance than senior women. For both sexes, partner-acceptance lowered across successive age cohorts. Internal consistencies were good.
Results support the use of the German version of the Self-Image Scale in research and clinical practice. Research directions include validation in further diseases, collecting normative data across countries, and dyadic research, particularly exploring partner-acceptance across the life span.
自我形象量表是一种自我报告式的测评工具，最初是为癌症女性患者设计的。该量表有两个分量表，分别评估外貌满意度（自我接纳）和对伴侣对外貌接受程度的感知（伴侣接纳）。本研究旨在通过以下方式提高自我形象量表的实用性：1）确认自我形象量表德语版本的两因素结构；2）检验跨性别和年龄组的测量不变性和有效性；3）收集一般人群的常模数据。
采用验证性因子分析方法，对来自德国普通人群的随机样本（N=1367）进行分析。评估了测量不变性、量表信度和有效性。
支持了最初的两因素结构和跨性别与年龄组的测量不变性。女性的自我接纳程度显著低于男性。青少年和年轻成年女性的自我接纳程度高于老年女性。对于两性来说，伴侣接纳程度随着年龄的增长而逐渐降低。内部一致性良好。
结果支持在研究和临床实践中使用德语版自我形象量表。研究方向包括在其他疾病中的验证、跨国家的常模数据收集以及对偶研究，特别是探索伴侣接纳在整个生命周期中的变化。
