The "Self-learning group" was designed to provide a description of the goals of the course and a reading of the Atomic Habits book. In the first session, the goals of the study were explained, the basic abilities of the caregiver and the case, the games, the relationship, the main problems that the caregiver wanted to change, the "Parent Problem Checklist" to help assess the caregiver's direction in identifying their own expectations, and the caregiver's perceived barriers and difficulties. The next 8 weeks of the course are based on the parents' self-study progress, and the study provides an online platform or a paper sheet to keep track of the self-study process and to contact the researcher at any time if there are any unexpected situations or problems. The record sheets were returned at the end of the 8-week period, and the self-study group received a face-to-face consultation at the end of the post-test.

Hybrid group used Atomic Habits (20-minute audiobook format), a role structure and a game structure, online schedule reminders more than twice a week and individual counseling sessions (online and physical) for one to two total interventions. The online schedule reminders consisted of four major habits, each with four concepts, to adapt the online audiobook interventions to the caregivers' relationship-building habits with the children A total of 16 sessions are delivered. Parents simply receive the course through digital media and complete the online schedule reminder within the course progress, narrowing down the indicators of habit change and achieving behavioral change through multiple executions.

Atomic Habits (20-minute audiobook format), a role structure, and a game structure, online schedule reminders more than twice a week, and individual counseling sessions (online and physical) with one to two total interventions. The content of the online schedule reminders consisted of a total of four concepts for each of the four major habits, and a total of 16 sessions of the online audiobook interventions were adapted for the caregivers' relationship-building habits with the children.

A 4-point scale was used to understand parents' performance in knowledge, practice, participation, time, and use of resources in the implementation of the curriculum. The scale is "1" for totally disagree, "2" for somewhat agree, "3" for mostly agree, and "4 " indicates full agreement.

By assessing parents' confidence and satisfaction with their role as a parent, 17 questions were asked on a 6-point scale ranging from "1" for strong agreement to "6" for strong disagreement, with higher scores indicating higher levels of parental confidence. The higher the score, the higher the parent's confidence. The scale is divided into two components, PSOC-E and PSOC-S, which reflect parental frustration, anxiety, and motivation, respectively, and the latter reflects competence, problem solving, and ability to perform the role of a parent. The Parental Effectiveness Scale (PSOC-E), which measures overall parental effectiveness, has a good internal reliability (Cronbach's alpha) of 0.76, while the Parental Satisfaction Scale (PSOC-S) has a good internal reliability (Cronbach's alpha) of 0.75; and can be used with caregivers of children of all ages.

The internal consistency of each subscale ranged from .856 to .908, and the total scale reached .947, representing a high level of consistency in the content of this scale.
