It is a theory proposed by Dr Murray Bowen which states that the individual cannot be seen in isolation, family is a place where interconnected and interdependent individuals (Khan, 2022). According to this theory family members are intensely emotionally connected. The family system theory states that a family functions as a system where in each member plays a specific role and must follow certain rules (Khan, 2022). Based on the roles within the system people are expected to interact with and respond to one another in a certain way. The family system theory encourages nurse to view both the individual clients as participating members of a whole family major strength of the system framework is that it views families from both a subsystem and supersystem approach.


The developmental phases of a family are referred to as the stages in a family life cycle. They include unattached adults, married adults, childbearing adults, newly married adults, school age children, teenage years, middle aged and retired adults. The family life cycle is a series of stages through which family may pass over time.

Biological ecological system theory

Bronfenbrenner’s research focused on the impact of social interaction on child development (Roe, 2019). Bronfenbrenner believed that a person’s development was influenced by everything in the surrounding environment and social interactions within it (Roe, 2019) Its strength includes importance of good environment for growth of children as environment shapes a child, its weakness is it is difficult to implement due to standards of living as a nurse the family system is important. as health of an individual translates to the health of the entire family. individual health can create positive or negative emotions to other members of the family.


Family systems theory is a way of thinking about how people act. It says that the family is a social system that is complicated (Fosco, 2019). An approach called theory helps us understand how people work. The theory looks at how people interact with each other in a family setting and how the family fits into the bigger picture.

It is good that families help the community, treat their families as a whole, and learn about how human resources affect the physiological functioning of a person. The family systems theory is good at these things. Weaknesses of this theory include cultural differences between families, bias, and problems with money, the model is for the literate and the state of intellect is honoured at the expense of feelings.

According to Duvall’s theory, families move through stages in a specified order after members of a family master each stage’s task (Hareven, 2019). The theory is centered on traditional intact families and concentrates on the sequential changes experienced by families in their life course. The family cycle helps to emphasize the effects of marriage, divorce, and deaths in families. The life cycle can be divided into three family formation, family expansion, and family contraction in the following stages. A family cycle can be defined as the stages of the family, including Unattached adult, marriage, childbearing and parenting, the launch of adult children, middle-aged adults, and retirement.

The bioecological theory of development posits that human growth is a transactional course. Their interactions with the environment influence a person’s development (Crawford, 2020). The theory goes beyond the developmental stages in a child during growth and how the child interacts with the environment. Bronfenbrenner formulated this bioecological theory of development. He defines the theory as a lifelong change in how a person deals with and observes his environment. Bronfenbrenner’s ecological theory and interaction with the environment, later renamed bioecological systems theory, focuses on the child’s environment and the quality of what they get exposed to. The theory suggests that an enriching environment makes a child’s growth and development of the brain move at a faster rate. An environmental surrounding influences a child’s opportunity for learning new skills.

The family systems theory will be the best in helping public health nurses in achieving a desirable outcome. The theory will help the nurses because generally the theory helps in community work and treating of patients and families.
