Coagulation disorders affect approximately one percent of the global population, with hemophilia being the most common (
1). Hemophilia, an X-linked disease, is caused by deficiency or absence of coagulation factors IIIV or IX (
2,
3). The prevalence of hemophilia A is higher than expected, with approximately 9.5 per 100,000 male births reported worldwide in 2020 (
4). The World Hemophilia Association estimates that about 400,000 people worldwide and 8,200 people in Iran with the disease (
2). Both types of hemophilia A and B are characterized by spontaneous and excessive bleeding after accidents or surgery (
5). Hemophilia patients face an increased risk of joint bleeding (typically in knees, elbows, and ankles), intraperitoneal and intracranial bleeding, as well as bleeding during and after surgery. Children with hemophilia require constant care due to pain, bleeding, and complications related to treatment (
2). The condition negatively impacts daily activities, interpersonal communication (
6,
7), and overall life satisfaction (
8). Life satisfaction is the most comprehensive assessment of a person’s life condition, the individual themselves, and the core of psychological existence, serving as a key evaluator of mental health (
9). Satisfaction with life is important in several ways includes ensuring mental-physical health, increasing life expectancy, and providing happiness for humans (
10). Those who are satisfied with their lives experience have more positive emotions, appreciate the events around them, and have better mental health (
11).
One of the criteria for determining the degree of desirability of the quality of life is happiness, defined as a positive emotional phenomenon that is necessary for humans and gives meaning to life (
12). Happiness is a significant element in life, and the lack of happiness leads to serious consequences related to health. This lack of happiness may be associated with symptoms of depression, reduced cognitive ability, intense feelings of emptiness, abandonment, frequent visits to the doctor, and a reduced quality of life. The operational definition of happiness, designed based on the Oxford Happiness Questionnaire, considers it as a construct with three important parts: The frequency and degree of positive emotion, the average level of satisfaction during a period, and the absence of negative feelings (
13).
Caregivers of children with hemophilia face unique challenges related to compliance and self-care for these children (
14). Therefore, a comprehensive approach involving the cooperation and participation of these caregivers is essential. Family-centered empowerment is one such approach that enables families to adapt to various life situations (
2). Family empowerment enhances patients' knowledge, attitude, and performance, accelerates recovery, and reduces disease-related complications (
