Psychometric properties of the French Infant-Toddler Working Alliance Inventory Short version (IT-WAI-S).

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.

Predictive factors for the outcome of emotional and/or behavioural disorders in 18- to 48-month-old children after parent-child psychotherapy: Protocol of a European prospective cohort study.

OBJECTIVES: Several studies have shown that in young children, behavioural and/or emotional disorders are more difficult to manage than regulatory disorders. Moreover, data are lacking on outcome predictive factors. This article presents a short synthesis of previous research about outcome predictive factors in child psychiatry. It also describes the protocol of a longitudinal observational European multicentre study the main objective of which was to identify predictive factors of behavioural and emotional disorder outcome in toddlers after parent-child psychotherapy. The secondary objectives were to study predictive factors of the outcome in parents (anxiety/depression symptoms) and parent-child relationship. METHOD: In order to highlight medium-effect size, 255 toddlers (age: 18 to 48 months) needed to be included. Outcomes will be assessed by comparing the pre- and post-therapy scores of a battery of questionnaires that assess the child's symptoms, the parents' anxiety/depression, and the parent-child relationship. Multivariate linear regression analysis will be used to identify predictive factors of the outcome among the studied variables (child age and sex, socio-economic status, life events, disorder type, intensity and duration, social support, parents' psychopathology, parents' attachment, parent-child relationships, therapy length and frequency, father's involvement in the therapy, and therapeutic alliance). EXPECTED RESULTS AND CONCLUSION: This study should allow identifying some of the factors that contribute to the outcome of externalizing and internalizing disorders, and distinguishing between pre-existing and treatment-related variables. It should also help to identify children at higher risk of poor outcome who require special vigilance on the part of the therapist. It should confirm the importance of therapeutic alliance.

[Infants' attachment security in a vulnerable French sample]. / Sécurité de l'attachement des jeunes enfants dans une population française vulnérable.

INTRODUCTION: Attachment is a long lasting emotional link established between infants and their caregivers. The quality of early relationships allows infants to safely explore their environment and contribute to the establishment of a broad range of social skills. Several intervention programs targeting infant attachment have been implemented in different contexts, showing diverse degrees of efficacy. OBJECTIVE: The present paper describes, for the first time, children's attachment quality distributions in a French multi-risk population, with a preventive intervention, usual or reinforced. METHOD: In the CAPEDP study (Parenting and Attachment in Early Childhood: reducing mental health disorder risks and promoting resilience), a sub-sample of 117 women was recruited to assess the effects of this home-visiting program on children's attachment security. With that intent, the Strange Situation Paradigm was used when infants were between 12 and 16 months of age. RESULTS: In the intervention group, 63% (n=41) of the infants were coded as secure, while 15% (n=10) of them were coded as insecure-avoidant and 22% (n=14) as insecure-ambivalent/resistant. 56% (n=29) of control group infants (usual care) were coded as secure, while 27% (n=14) were coded as insecure-avoidant and 17% (n=9) as insecure-ambivalent/resistant. Even if the percentage of children with a secure attachment in the reinforced intervention group was higher than that of the control group, this difference did not reach the threshold of significance [Chi2 (2)=2.40, P=0.30]. DISCUSSION: Intervention group distributions were closer to normative samples, and these distributions show the clinical impact of our program. In general, preventive interventions focused on attachment quality have moderate effects but, in our case, several factors might have contributed to lower the statistical impact of the program. Firstly, the control group cannot be considered has having received zero intervention for two reasons: (a) the French usual perinatal health system (Maternal and Infant Protection System) is particularly generous and (b) the effect of this usual system might have been increased by the project intensive assessment protocol (6 visits during 28 months). Secondly, it is possible that the full effect of the intervention had not yet been detected because, when a child's attachment was assessed, only two thirds of the intervention visits had been performed (29 of 44 visits). A "sleeper effect" is still possible: we hope that a more clear result will be seen when children are assessed again, at 48 months, in our follow-up study (CAPEDP-A II). By clarifying the mechanisms involved in the development of a secure attachment, our study aims to contribute and refine the development of early preventive intervention strategies in high perinatal and psychosocial vulnerability contexts.
