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).
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.
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.
The two IT-WAI-S versions showed good psychometric properties and could be used to study the therapeutic alliance in young children.
治疗联盟在婴幼儿治疗中研究较少，且没有专门适用于该人群的工具。然而，我们基于工作联盟量表开发了婴幼儿工作联盟量表简版（IT-WAI-S）。本研究的目的是评估这个原创法语工具两个版本的心理测量特性，这两个版本分别是家长版（IT-WAI-SP）和治疗师版（IT-WAI-STh）。
本研究纳入了227个因孩子存在情绪或行为障碍而前来咨询的家庭，孩子年龄在18至48个月之间。量表在最初的三次治疗 session 中填写。对IT-WAI-S的可接受性、内部效度、信度和预测效度（与孩子及母亲的治疗结果的关联）进行了评估。
验证性然后探索性因素分析揭示了两个量表的三因素结构：护理关系的负面体验、积极联盟和与孩子的联盟。两个版本的可接受性、可重复性和结构效度都令人满意。两个版本都预测了孩子的治疗结果。IT-WAI-SP还预测了母亲的治疗结果。IT-WAI-STh给出的结果更具可重复性，而IT-WAI-SP是孩子治疗进展的更好预测指标。
IT-WAI-S的两个版本都显示出良好的心理测量特性，可用于研究幼儿治疗中的治疗联盟。
