Abstract

Objective: Therapeutic alliance has been little investigated in infant and toddler therapy, with no tools specifically adapted to this population. However, we have developed the Infant-Toddler Working Alliance Inventory-Short form (IT-WAI-S) which is based on the Working Alliance Inventory. The aim of this study was to assess the psychometric properties of this original French tool, in its two versions: for parent (IT-WAI-SP) and for therapist (IT-WAI-STh).

Method: This study included 227 families consulting with their 18-48-month-old child for emotional or behavioral disorders. The scales were filled in at the first three therapy sessions. The IT-WAI-S acceptability, internal validity, reliability and predictive validity (association with child and mother's outcomes) were evaluated.

Results: Confirmatory then exploratory factor analyses revealed a three-factor structure for the both scales: Negative Experience of Care Relationship, Positive Alliance and Alliance with the Child. Acceptability, reproducibility and construct validity were satisfactory for both versions. The two versions predicted the child's outcome. The IT-WAI-SP predicted also the mother's outcome. The IT-WAI-STh gave more reproducible results, whereas the IT-WAI-SP was a better predictor of the child's progress.

Conclusion: The two IT-WAI-S versions showed good psychometric properties and could be used to study the therapeutic alliance in young children.

法国婴幼儿工作联盟量表简版（IT-WAI-S）的心理测量特性。

目的：在婴幼儿治疗中，对治疗联盟的研究很少，也没有专门适用于这一人群的工具。不过，我们在工作联盟量表的基础上开发了婴幼儿工作联盟量表-简表（IT-WAI-S）。本研究的目的是评估这一法国原版工具的两个版本的心理测量特性：家长版（IT-WAI-SP）和治疗师版（IT-WAI-STh）：这项研究包括 227 个为其 18-48 个月大的孩子进行情绪或行为障碍咨询的家庭。在前三次治疗过程中填写量表。对IT-WAI-S的可接受性、内部效度、可靠性和预测效度（与儿童和母亲结果的关联）进行了评估：结果：先确认后探索的因子分析显示，两个量表都具有三因子结构：护理关系的消极体验、积极联盟和与儿童的联盟。两个版本的可接受性、可重复性和建构效度均令人满意。两个版本都能预测儿童的结果。IT-WAI-SP 还能预测母亲的结果。IT-WAI-STh得出的结果更具有可重复性，而IT-WAI-SP则能更好地预测儿童的进步：两个版本的 IT-WAI-S 显示出良好的心理测量特性，可用于研究幼儿的治疗联盟。
