This article describes the psychometric properties and factor structure of the Working Alliance for Mandated Clients Inventory (WAMC-I). First, we explain how, in contrast to other European jurisdictions such as England and Wales, community supervision in Belgium remains a specific form of social work practice, which is referred to as “social work under judicial mandate” (Devos, 2009: 18). Just as in general social work practice, the professional relationship between practitioners and clients1 is considered to be of paramount importance in community supervision practice. To capture the essence of this professional relationship, we draw on the pan-theoretical concept of the Working Alliance (WA) (Bordin, 1979) and a theoretical adaptation of this concept for the field of community supervision (Menger, 2018). Building on this theoretical adaptation, an instrument to measure the WA was developed for the Dutch context of community supervision: the WAMC-I. The objective of the present study is to assess the psychometric properties and factor structure of the WAMC-I with a sample of justice assistants2 and clients in the Flemish Houses of Justice. This study offers an elaborated conceptualization and operationalization of the concept of the WA. Preliminary tests on the psychometric properties and factor structure of the WAMC-I show that three factors on the WAMC-I for professionals proved valid and reliable: trust, clarity of rules and regulations and reactance. However, tests on the WAMC-I for clients showed no factor solution. Based on the theoretical framework of the WA and scientific-methodological arguments we express our reservations about the use of the WAMC-I and offer suggestions for improvement.

在佛兰德社区监督实践中衡量工作联盟的质量：对授权客户清单工作联盟的验证研究

本文描述了强制客户清单工作联盟 (WAMC-I) 的心理测量特性和因素结构。首先，我们解释了与英格兰和威尔士等其他欧洲司法管辖区相比，比利时的社区监督如何仍然是一种特定的社会工作实践形式，被称为“司法授权下的社会工作”（Devos，2009：18） . 正如在一般社会工作实践中一样，从业者和客户之间的专业关系 1 被认为在社区监督实践中至关重要。为了捕捉这种专业关系的本质，我们借鉴了工作联盟 (WA) (Bordin, 1979) 的泛理论概念以及该概念在社区监督领域的理论改编 (Menger, 2018)。在这种理论适应的基础上，为荷兰社区监督环境开发了一种衡量 WA 的工具：WAMC-I。本研究的目的是评估 WAMC-I 的心理测量特性和因素结构，其中包括佛兰芒司法院的司法助理 2 和客户样本。本研究对 WA 的概念进行了详细的概念化和操作。对 WAMC-I 的心理测量特性和因素结构的初步测试表明，WAMC-I 上的三个因素被证明是有效和可靠的：信任、规则和规定的清晰性以及反应性。但是，针对客户的 WAMC-I 测试显示没有因子解决方案。
