Self-relation is a profound connection that influences one's life. As such, it presents an important topic for various areas of research and psychotherapy. The goal of this study was to develop and evaluate a brief scale that would assess positive aspects of self-relation.
The Positive Self-Relation Scale (PSRS) consists of 16 items divided into 4 subscales - Self-Acceptance, Self-Confidence, Authenticity and Assertiveness, and Fulfilled Experience. Two samples were used for the evaluation of its content and factor structure. The final sample's data used for validation assessment. This sample consisted of 1234 adults from a general population (mean age 34.8±14.2 years, 70.8% women). All participants completed PSRS. Subgroups also filled in Rosenberg Self-Esteem Scale (RSES), Adult Dispositional Hope Scale (ADHS), Beck Depression Inventory-II (BDI-II), Liebowitz Social Anxiety Scale (LSAS), and Dissociative Experiences Scale (DES).
Differences in scores among demographic groups were small to none. Internal consistency was good (Composite Reliability Coefficients - the whole scale: 0.93; the subscales: 0.73-0.80). Temporal stability, assessed 2 weeks apart, was satisfactory (intraclass correlation coefficients - the whole scale: 0.86, the subscales: 0.60-0.82). Factor loadings in confirmatory factor analysis were 0.45-0.80, fit indices mostly showed an adequate model. The correlation coefficients between PSRS and RSES/ADHS were strong (r=0.79/0.55). The scale also strongly correlated with LSAS, BDI-II, and DES (r=-0.61/-0.48/-0.30, all ps<0.001).
PSRS showed adequate psychometric properties in the general population. Future studies should include clinical samples. The areas of application lie mainly in research and psychotherapy.
自我关系是一种深刻的联系，会影响一个人的生活。因此，它是各个研究领域和心理治疗中的一个重要课题。本研究的目的是开发并评估一个简短的量表，用以评估自我关系的积极方面。
积极自我关系量表（PSRS）由16个项目组成，分为4个分量表——自我接纳、自信、真实性与坚定性以及充实体验。使用了两个样本对其内容和因子结构进行评估。最终样本的数据用于效度评估。该样本由1234名来自普通人群的成年人组成（平均年龄34.8±14.2岁，女性占70.8%）。所有参与者都完成了PSRS。各亚组还填写了罗森伯格自尊量表（RSES）、成人气质性希望量表（ADHS）、贝克抑郁量表第二版（BDI-II）、利博维茨社交焦虑量表（LSAS）以及解离体验量表（DES）。
不同人口统计学组之间的得分差异很小或不存在差异。内部一致性良好（组合信度系数——总量表：0.93；分量表：0.73 - 0.80）。相隔两周进行评估的时间稳定性令人满意（组内相关系数——总量表：0.86，分量表：0.60 - 0.82）。验证性因子分析中的因子载荷为0.45 - 0.80，拟合指数大多显示模型合适。PSRS与RSES/ADHS之间的相关系数很强（r = 0.79/0.55）。该量表与LSAS、BDI-II和DES也有很强的相关性（r = -0.61/-0.48/-0.30，所有p值均<0.001）。
PSRS在普通人群中显示出足够的心理测量学特性。未来的研究应纳入临床样本。其应用领域主要在于研究和心理治疗。
