Intervention group (I) will be receiving a psychoeducational intervention along with routine care they are getting in the hospital

Comparison usual care and Leaflet of the information. At the end of the trial these also get the video and educational sessions as intervention group.

. Intervention group (I) will receive psychosocial education which will be consist of two parts. 1) Face to Face 2) Community based intervention.

1. Face to face: This face to face session will be consisting of 30-minute session soon after inclusion into the study. A leaflet consisting of all information will be provided to all the patents taking part in the study.
2. Community Based Intervention: In community based interventions prerecorded videos about all the topics covered in face to face session will be made available to parents via a secure online platform. Parents can easily browse it easily when they need it. These videos will be recorded in local language (Urdu), which is easy to understand for almost all the people.

Stress changes will be measured via Parental Stress Scale (PSS). The PSS is scored by summing the scores for all 18 items. The total score can range from 18 to 90, with higher scores indicating higher levels of parental stress. The PSS also has two subscales: Child Demandingness (CD) and Parental Competence (PC). PSS scores are interpreted based on the following ranges: 18-37 low stress, 38-56 Moderate stress and 57-90 as high stress.

Changes on parental quality of life will be assessed through World Health Organization Quality of Life-Bref (WHOQOL-Bref). The WHOQOL-Bref instrument is composed by 26 items, which are organized in 4 specific domains: Physical (7 items), Psychological (6 items), Social Relationships (3 items), Environment (8 items) and a general QoL facet (2 items). All items are quoted from 1 to 5. Three items, related to questions posed negatively (Q3, Q4 and Q26), must be reversed (the calculation implies the subtraction of their value to six units). The results are transformed on a scale of 0 to 100. Each domain score is computed through the formula: [(sum of all items - number of items) / (4x number of items)] x 100. Higher scores correspond to better quality of life.

Depression in parents of children with CHD will be assessed through DASS. The Depression Anxiety Stress Scales (DASS) is a self-report questionnaire that assesses the three most common negative emotional states: depression, anxiety, and stress. It is a widely used tool in research and clinical settings to measure these symptoms and their impact on an individual's well-being. Each item on the DASS is rated on a 4-point Likert scale, ranging from 0 (never) to 3 (almost always). The total score for each subscale is calculated by summing the scores for the items on that subscale. Higher scores on each subscale indicate more severe symptoms.
