iPACT: Effectiveness of a Parent-mediated Intervention With PACT on Children With ASD
Study Details
Study Description
Brief Summary
Autism Spectrum Disorder (ASD) is a neuro-developmental disorders. There are different types of interventions. Among these interventions Early Start Denver Model (ESDM) and Preschool Autism Communication Therapy (PACT) have proved efficacy at short and long term. PACT is the therapy with the highest evidences when Parents delivered the intervention themselves.

Detailed Description
In PACT, parents are guided, generally in face to face, by a professional to improve the synchrony and communication with their children with ASD. Then, it is recommended to the parents to practice the therapy daily at home. In France, this type of early intervention is poorly developed and is only accessible in specialized centers located in large urban centers. Guiding parents by videoconferencing could make this intervention accessible to families in undeserved areas. The objective of this study is to evaluate the effectiveness of a PACT intervention delivered by parents and guided by videoconferencing, on the autism in their children with ASD, aged 18 to 36 months at the inclusion.
This study is a multicenter (5 centers), two-parallel-group, randomised controlled trial. It will compare a group of children receiving the usual therapy (TAU) and a group receiving TAU plus the PACT intervention. The primary outcome is the autism symptoms measured with the ADOS-2 (Autism Diagnostic Observation Schedule) at 12 months. A total of 238 children will be included in the study (119 per group).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Sham Comparator: a group of children receiving the usual therapy (TAU) Children will receive therapies available in the community as speech language therapist or occupational therapist. |
Other: Treatment As Usual (TAU)
Children will receive therapies available in the community as speech language therapist or occupational therapist.
|
| Experimental: a group of children receiving TAU plus the PACT intervention. Professionals guide parents in the PACT therapy by videoconference. Sessions between parent and professionals are every 15 days for 6 months. Each session lasts one hour. At the end of the 12 sessions, additional booster sessions (one session per month over 6 months) will allow parents to maintain their skills. Parents will use therapy with their children in daily home practice. The aims of PACT therapy is to improve synchrony in the communication between the child and the parents. Improvement of the synchrony will mediate the decrease of autism symptoms of the child. |

Outcome Measures
Primary Outcome Measures
- Autism symptoms [12 months]
Autism symptoms measured with ADOS-2 ( Autism Spectrum Observation Schedule version 2)
Secondary Outcome Measures
- Social Interactions of the child [6 and 12 months]
Social Interactions measured with the total score of the BOSCC (Brief Observation of Social Communication Change). The test contains 9 items that are meant to capture the quality of a child's social interaction, for which the total scores ranges from 0 to 45, and 3 items describing restricted a repetitive behavior, which is also part of the ASD symptomatology, the total score of which ranges from 0 to 15. Three additional items are coded to add information on symptoms that might be present although they are not specifically part of the ASD syndrome, and refer to activity level, disruptive behavior, and anxious behaviors. The BOSCC total score consists in the sum of the total score obtained in the first twelve items (ASD specific symptoms), and ranges from 0 to 60, with the three extra items added separately to integrate information. In the total and subscale scores, higher scores correspond to more severe symptoms.
- Parent-child synchrony and initiative in communication [6 and 12 months]
Parent-child synchrony and initiative in communication measure with DCMA (Dyadic Communication Measure for autism)
- Number of words produced by the child [12 months]
Number of words produced by the child measured with global score of the french scale " Développement du Langage de Production en Français " (DLPF)
- Number of words produced by the child [12 months]
Number of words produced by the child measured with global score of the Mullen Scale of early learning (MSEL)
- Adaptative behavior [12 months]
Adaptative behavior measured with VABS (Vineland Adaptative Behaviour Scales 2). The Vineland Adaptive Behavior Scales (VABS; Sparrow et al., 1984) comprises four domains, that is, communication, daily living skills, socialization and motor skills, for assessing adaptive functioning in children aged 3 to 12 years old. The raw score in each domain and total raw score are converted to an age-equivalent score. The domain scores are also expressed as standard scores with a mean of 100 and standard deviation of 15. The range for each subscale is from 20 to 140. The subscales are summed to compute a total score, ranging from 80 to 560. The higher the scores are, the better adaptive functioning the children achieve.
- Autism Family Experience [12 months]
Measured with the questionnaire Autism Family Experience. The Autism Family Experience Questionnaire (AFEQ) is a parent/Caregiver form used to measure impact of autism interventions on family experience and quality of life. The AFEQ included both positively and negatively worded statements and is scored on an order scale: 1 = always to 5 = never, with an option for "Not Applicable". 4 domains are evaluated : experience of being a parent, family life, child development understanding and social relationships, child symptoms.A higher score means a worse outcome.
- Characteristics of the parents [12 months]
Measured with General Health Questionnaire (GHQ-28). The GHQ-28 is a 28-item self-report used to psychological stress. The GHQ focuses on two main classes of phenomena: 1) inability to carry out one's normal healthy functions; and 2) emergence of new phenomena that are distressing. It consists of 28 items, divided into 4 sub-scales. It contains 4 sub-scales: A (somatic symptoms), B (anxiety/insomnia), C (social dysfunction), and D (severe depression). There are 4 possible answers to each question. The Likert scoring system assigns a value from 0 to 3 to each of the 4 possible answers. A higher score means a worse outcome.
- Characteristics of the parents [12 months]
Measured with ISP (Indice of Parental Stress). A self-report inventory designed to measure the overall level of parenting stress an individual is experiencing and it examine stressors associated specifically with the parental role and do not include stresses associated with other life roles and events. The PSI-SR has strong psychometric properties and has been used in a number of studies of autism and parent training. It contains 36 items, each rated on a five-point Likert scale (1-5), with higher scores indicative of more parenting stress and includes Parental Distress (PD), Parent-Child Dysfunctional Interaction (P-CDI) and Difficult Child (DC) sub-scales.
