Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
- BBPTViet includes a one-off training course that provides behavioral modification skills to parents of preschool children with disruptive behaviors and up to 4 times of follow-up support via telephone, email, Facebook messenger in 8 following weeks at the discretion of the participant.
- The course focuses on analytical skills to understand the meaning of behavior and parenting practices to increase desirable and reduce undesirable behaviors of the child. The skills involve (i) to analyze the relationship between the behavior and its antecedent and consequence, (ii) to identify the function of behavior, and (iii) to select appropriate solutions. The practices include special time, descriptive praise, tangible reward, physical affection, problem-solving, effective command, ignore, and time-out.
- The course consists of four dyadic 50-minute sessions and is organized at the clinic on 2 consecutive Saturdays. The first 2 sessions will focus on theory training with active learning skills, including didactic teaching, interactive lecturing, role play, brainstorming. The last 2 sessions will be the time for discussing, brainstorming, rehearsal, and giving feedback. The participants will practice the trained skills and strategies with their child as their homework during the break time after the first 2 sessions. Therefore, the first 2 sessions are undertaken on one Saturday, and the remaining 2 sessions are completed on the following Saturday. The course contains no more than 25 parents who will group-discuss, brainstorm, and role-play under the instruction of facilitators. The main facilitator who delivers the course and provides follow-up support is a clinical psychologist or a health professional with at least 3 years' experience in the child behavior field.
- Material includes a training manual that is specifically designed for this study, a manual-based PowerPoint presentation, and a fidelity checklist. The facilitator must use the presentation to train the parents and self-rate with the checklist to adhere to the intervention.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomization will be generated at the beginning of the assessment day before the interventions. Sealed opaque envelopes that contain either the BBPTViet or CAU will be arranged in a sequence based on the result of the randomization in a container. The container then is brought to and kept by the secretaries. Both doctors who examine the parent-child dyad and secretaries will not involve in the concealment procedure.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will assign participants to either the control or intervention group according to block randomization generated by the computer software WINPEPI (PEPI-for-Windows) to achieve the balance of 1:1 allocation. The block size is 6 but it will not be disclosed to ensure concealment.

Efficacy
Statistical methods / analysis
We will use SPSS version 22 and R to conduct analyses based on intention-to-treat (ITT) principles. For all tests, we will use 2-sided p-values with alpha = < 0.05 level of significance. P-values will be reported to three decimal places. Hereafter is the statistical analysis plan:
- We use descriptive statistics to present the participant’s characteristics and outcomes (mean, standard deviation, frequency). Then, we will test the equivalence between 2 intervention arms at pre-intervention. Appropriate statistical analysis will be used to control the differences between two arms if they are available.
- We use General linear model to test the association of independent variables, such as intervention type, parent’s age group, parent’s education level, address, child’s gender, assessment time with the outcomes.
- To assess the impact of the training program on child behavior, we analyze the reliable improvement/deterioration and reliable recovery. The former counts the number of children having statistical differences in score of ECBI pre- and post-intervention. The latter informs the number of children having statistical differences in score of ECBI pre- and post-intervention AND the scores move below the clinical cut-off. We also categorize participants based on the clinical cut-off score of the ECBI at baseline then compare the outcomes between and among those categories at post-intervention. Finally, we calculate the number needed to treat (NNT) to identify how many parents needed to be trained to have one child's improvement and/or recovery.

Summary
Brief summary
Disruptive behaviors (DB) are normative among preschoolers, reducing as children mature. In some children, however, BDs with high frequency and intensity may lead to disruptive behavior disorders which relate to physical and mental health problems, difficulties in interpersonal relationships, education, and work. Studies show that Brief behavioral parent training (BBPT) helps to decrease child DBs, increase positive parenting practices but most of them were implemented in high-income and non-Asian countries.
The present project is a randomized, single-blind, controlled trial. It will test the hypothesis that the BBPT Vietnamese (BBPTViet) will help reduce preschooler DBs, enhance positive parenting practices, and improve parent-child interaction quality better than the care as usual (CAU) in Vietnam. We also examine the effects of the BBPTViet on marital conflict status, parenting self-efficacy, and parent mental health condition compared to CAU. Eligible participants are parents whose 3 to 6-year-old child often displays some disruptive behaviors. During 6 months of recruitment, 90 parents will be randomly assigned to attend either the BBPTViet or CAU. The BBPTViet which consists of four 50-minute sessions will be delivered in 25-people groups to instruct participants in the use of positive parenting practices, while the CAU will provide a 20-minute individual consultation on specific parenting practices to participants. Outcome assessments will be conducted before, at 1 month, 2 months, and 6 months after the completion of the training course.
