Study Retention Rate
37 Participants

PRIMARY outcome

Timeframe: Session 1 and Session 8 (approximately 5 minutes to complete questionnaire)

Population: Intent-to-treat population (excluding participants who were withdrawn from the study per investigator decision).

To assess treatment acceptability, the study used the Cooperation and Helpfulness sub-scales of the Helping Alliance Questionnaire (HAQ). The HAQ was administered to parents after session 1 and 8. The subscales, Helpfulness and Cooperation, are scored on a Likert scale from "Strongly feels it's true" (+3) to "Strongly feel it's not true" (-3). The sub-scales' total scores ranges are 15- to 15 for Helpfulness and -18 to 18 for Cooperation. A higher score indicates a better outcome. The average score was calculated if more than one parent responded.

PRIMARY outcome

Timeframe: Session 1 (approximately 5 minutes to complete questionnaire)

Population: Intent-to-treat population (excluding participants who were withdrawn from the study per investigator decision).

To assess treatment acceptability, the study used the Therapist Suitability and Patient Expectancy measure (TSPE). The TSPE was administered to parents after session 1. The scale is measured from 0-10 (with 0 as the lowest rating and 10 as the highest rating). The average score was calculated if more than one parent responded. A higher score on the TSPE indicates a better outcome.
