Reliability and Validity of the Therapy Attitude Inventory in Caregivers Receiving Internet-Delivered Parent Child Interaction Therapy for Young Children with Developmental Delay

Despite common use of the Therapy Attitude Inventory (TAI) to measure satisfaction with parenting interventions, psychometric support has only been demonstrated in predominantly White caregivers of typically developing children following clinic-based treatments. Additionally, the reliability and validity of the Spanish version of the TAI have not been assessed. The present study examined the reliability and validity of the English and Spanish versions of the TAI among mostly Hispanic/Latinx caregivers of children with developmental delay (DD; n = 65) following Internet-delivered Parent-Child Interaction Therapy (iPCIT). Internal consistency was excellent for both versions. Convergent validity was demonstrated by a strong correlation with the Client Satisfaction Questionnaire-8. Satisfaction was predicted by improvements in child behavior and parenting skills, as well as reductions in caregivers’ negative feelings about parenting, following treatment. These findings support use of the TAI with Spanish-speaking families, families from minoritized backgrounds and with children with DD, and following telehealth interventions.
