Examining the Active Ingredients of Consultation to Improve Implementation of a Parent-mediated Intervention for Children With Autism in the Community Mental Health System

Case Penetration

时间窗: 23-26 weeks

Case penetration will be measured weekly using the Penetrability Formula and will be expressed using provider report of the total number of Project ImPACT cases on their caseload divided by the total number of eligible clients with ASD on their Medicaid Autism Benefit caseload. This is expressed as a percentage. Higher percentage values indicate higher case penetration.

Treatment Adherence

时间窗: 23-26 weeks

The Project ImPACT Coaching Fidelity Checklist is a measure of treatment adherence. It uses a 3-point scale -- Observed (1), Partially Observed (.5), and Not Observed (0). Higher scores indicate higher treatment adherence. Based on scoring guidelines for this measure, scores for each item are multiplied by an item-specific weight value. Scores for each item are then summed and divided by the total number of items scored, yielding a score ranging from 0 to 100.

Parent-mediated Intervention Competence

时间窗: 23-26 weeks

Parent-mediated intervention competence will be assessed via Parent Empowerment and Coaching in Early Intervention (PEACE) coding which utilizes a 5-point scale to assess for competency in delivering collaborative coaching techniques used in parent-mediated interventions. The scale used is: Never (1), Rarely (2), Sometimes (3), Often (4), and Almost Always (5). The minimum value on the scale is 1 and the maximum is 5. Higher scores indicate higher parent-mediated intervention competence.

Ratings of the Usability of Each Consultation Component

时间窗: 23-26 weeks

Clinicians reported on the usability of each consultation component weekly across the 4 weeks of each consultation condition using the Implementation Strategy Usability Scale (Lyon et al., 2021). This 10-item questionnaire uses a 5-point Likert scale to examine clinician perceptions about the complexity of using an implementation strategy. The scale is unidimensional and has no subscales. Based on scoring guidelines, a formula is used to calculate the total usability score, which ranges from 0-100. Higher scores indicate higher usability; higher scores indicate higher ratings of the participant's ability to use the strategy with ease. The formula involves the following: for each odd numbered item, subtract 1 from the Likert rating value to get the new value; for each even numbered item, subtract the Likert rating value from 5 to get a new value; then sum all new values and multiply by 2.5.

Ratings of Perceptions of Project ImPACT

时间窗: 23-26 weeks

Providers completed the Perceived Characteristics of Intervention Scale (PCIS; Cook et al., 2015) weekly about their perceptions of Project ImPACT. This 18-item questionnaire includes items related to various constructs from Rogers' Diffusions of Innovation theory (Rogers, 2010). All items are rated on a 7-point Likert scale and the overall PCIS score is established by computing the mean of all items. The minimum score is 1.00 and maximum is 7.00. Higher values indicate more positive perceptions of the intervention.

Child Social Communication Skills

时间窗: 23-26 weeks

The Autism Impact Measure has 41 items rated on a 5-point scale ranging from Never (1) to Always (5). The overall score is calculated by summing the scores on two scales (frequency and impact). Higher values indicate a higher frequency and impact of autism-related concerns child functioning. The minimum value is 82 and the maximum value is 410.
