Allergic rhinitis is defined as the inflammation of the nasal mucosa caused by one or more allergen sensitivities (Bayat & Erdem, 2021). It is a common disease in childhood (Noronha et al., 2017; Türkoğlu Babakurban et al., 2015). Allergic rhinitis symptoms can affect children's lives physically, psychologically, and socially (Noronha et al., 2017). Parents of children with allergic rhinitis report that it affects many aspects of their daily lives, such as school, sleep, emotional well-being, and physical health (Bosnic-Anticevich et al., 2020). Severe clinical findings (Sikorska-Szaflik & Sozańska, 2020), especially nasal symptoms like nasal itching, decrease the quality of life in children with allergic rhinitis (Dziekanski & Marcelino, 2017). There is a significant relationship between the intensity of ocular symptoms and nasal symptoms such as nasal congestion or itching and poor quality of life in children and adolescents (Devillier et al., 2016).

Allergic triggers such as house dust mites, mold, and pet dander are present in the home environment (Aldemir & Güclü, 2001; Bayat & Erdem, 2021; Gökce et al., 2010; Sipahi & Güler, 2017). Allergic rhinitis in children has been associated with certain home environment characteristics, and an increase in the number of environmental risk factors within the home has been linked to an increased risk of allergic rhinitis (Wang et al., 2015). Factors such as living in an apartment, keeping pets (Çobanoğlu et al., 2016), new furniture, dampness, presence of cockroaches, mosquitoes/flies (Wang et al., 2015), humidity and mold in the home (Cai et al., 2019), the presence of mites such as Dermatophagoides farinae and Dermatophagoides pteronyssinus in the home (Huang et al., 2019), and parental smoking (Çobanoğlu et al., 2016) are risk factors for allergic rhinitis in children. It has been reported that children exposed to more environmental risk factors are more likely to experience allergy symptoms (Castro et al., 2013).

Avoidance of allergens is one of the most important steps in the treatment of allergic rhinitis (Bayat & Erdem, 2021). Since children spend the majority of their time in the home environment, indoor allergen control is important in managing allergic diseases (Willy-Fabro et al., 2015). Certain adjustments are necessary in the home environment to protect against indoor allergens (Bayat & Erdem, 2021; Castro et al., 2013; Gökce et al., 2010). It is recommended to provide education to raise awareness among families regarding these modifications (Bayat & Erdem, 2021; Castro et al., 2013). Allergy intervention programs have been shown to be effective in reducing symptoms and improving the quality of life in children with asthma and/or rhinitis (Smith et al., 2016). Additionally, personalized nursing counseling has been found to have a positive impact on reducing symptoms in children with allergic rhinitis (Solís-Flores et al., 2017). This study was designed due to the scarcity of research investigating the impact of different nursing interventions on allergic rhinitis in children. The aim of this study is to investigate the effects of nursing interventions aimed at modifying the home environment on symptom control, quality of life, and the number of triggers in the home environment for children with allergic rhinitis and their parents.

H0a

There is no difference in the number of triggers in the home environment between children with allergic rhinitis who received nursing interventions aimed at modifying the home environment and those who did not.

H0b

There is no difference in the mean quality of life scores of children with allergic rhinitis who received nursing interventions aimed at modifying the home environment and those who did not.

H0c

There is no difference in the mean allergic rhinitis symptoms scores, including nasal discharge, nasal congestion, sneezing, nasal itching, and itching of the eyes, of children with allergic rhinitis who received nursing interventions aimed at modifying the home environment and those who did not.
