Parenting Stress in Mothers of Children with Congenital Heart Disease pptx

116 Asian Nursing Research ❖ September 2007 ❖ Vol 1 ❖ No 2 ORIGINAL ARTICLE INTRODUCTION Approximately 2–3 of 1000 infants are born with congenital heart disease (CHD) in Korea (Lee, Kim, Jung, Kim, & Choi, 2001). As a result of dramatic advances in the medical and surgical management of CHD, 85% of infants with CHD are now expected to survive to adulthood, and CHD is regarded as a chronic disease rather than a terminal one (Lee, 2001). However, the management of CHD involves repeated invasive procedures, hospitalization, and often prognostic uncertainty. All of these can be stressful for children and their families (Peterson & Harbaugh, 1995). Accordingly, parents continue to have concerns about how their child’s illness and treatment affect their child’s daily functioning, devel- opment, and overall wellbeing (Van Horn, DeMaso, Gonzalez-Heydrich, & Ericson, 2001). DeMaso, Beardslee, Silbert, and Fyle (1990) reported that the behavioral adjustment of children with CHD was significantly related to the level of parenting stress. The poor psychological adjustment Parenting Stress in Mothers of Children with Congenital Heart Disease Sunhee Lee 1 *, RN, MSN, Ji-Soo Yoo 2 , RN, PhD, Il-Young Yoo 2 , RN, PhD 1 PhD Candidate, College of Nursing, Yonsei University, Seoul, Korea 2 Professor, College of Nursing, Yonsei University, Seoul, Korea Purpose The main purposes of this study were to examine the relationships among uncertainty, social support and parenting stress in mothers of children with congenital heart disease (CHD) and to identify the factors related to parenting stress. Methods This was a survey study using a questionnaire. Fifty-one mothers of children with CHD were recruited at the pediatric cardiac outpatient clinic at one university-affiliated hospital in Seoul between July 14th and September 25th, 2006. Abidin’s Parenting Stress Index–Short Form, Mishel’s Parents’ Perception Uncer- tainty in Illness Scale, and Brandt and Weinert’s Personal Resource Questionnaire were used to collect data. Results The results of bivariate analysis showed that parenting stress was significantly related to social support, ambiguity, lack of clarity, and lack of information, but was not related to unpredictability, one of the subconcepts of uncertainty. Multiple regression analysis showed that parenting stress was significantly related to social support and Internet information. Conclusion Mothers who reported they had more social support and less uncertainty showed lower parent- ing stress. Also, the Internet could be an effective method to obtain information and to share child-rearing experiences with other mothers of children with CHD.

Mattie-Luksic, Javornisky, and DiMario (2000) reported that the factors that helped mothers to cope with their children’s disease were having information about the disease, communicating with knowledgeable professionals, understanding cause/treatment, and participating in a support group. One of the most significant difficulties encoun- tered by the parents of children with CHD is an inac- curate understanding of the problems related to the management of chronic illness (Chessa et al., 2005). Parents’ knowledge about their child’s health, dis- ease, treatment, and prevention of complications may promote better health behavior in their children by increasing the understanding of the cardiac prob- lems, improving compliance with treatment, and avoiding risk-taking behaviors (Clare, 1985). Many parents also look for support from other parents who have had similar experiences. Meeting with other parents creates a sense of belonging which reduces isolation (King, Stewart, & King, 2000). Other parents can provide a credible model of how to cope in a positive way with exceptional life cir- cumstances (Davis & Hall, 2005). Mothers of children with chronic diseases expressed the uncertainty of their children’s future. Van Dongen-Melman et al. (1995) reported that uncertainty and loneliness served as significant psy- chological stressors for the mothers of children with cancer. Boman, Lindahl, and Bjork (2003) said that mothers of children with cancer reported higher lev- els of uncertainty as well as anxiety, loneliness, and depression. Since CHD is regarded as a chronic dis- ease, mothers of children with CHD also reported higher levels of uncertainty. Linde (1982) reported that the mothers of children with CHD had problems not with the severity of disease but with uncertainty about the future, the cure plan and the outcome. Carey, Nicholson, and Fox (2002) reported that mothers of children with CHD suffer psychological distress due to uncertainty and fear for their child’s future. Sparacino et al. (1997) also said that most parents with children suffering from CHD express uncertainty with regard to the future of their child and about the difficulty of pushing their child to excel. However, it was difficult to find studies of Korean mothers with children with CHD. Therefore, the goals of this study were to (a) examine the relationship between general char- acteristics and parenting stress in mothers of children with CHD, (b) examine the relationships among uncertainty, social support, and parenting stress in mothers of children with CHD, and (c) determine the factors affecting parenting stress in mothers of children with CHD in Korea. METHODS Subjects Mothers of children with CHD were recruited at the pediatric cardiac outpatient clinic at one university- affiliated hospital in Seoul between July 14th and September 25th, 2006. It was the summer break period for elementary school children, which was when they visited the clinic for follow-up. Since elementary school children with CHD who have undergone total correction usually visit the clinic for follow-up once a year, they tend to visit the clinic during their break period. The age of the children with CHD ranged from newborn to 9 years old. The purpose of the research was explained and informed consent was obtained by the researcher. Those who had just been diagnosed with CHD were excluded because their experience of the illness was not sufficient to understand the questionnaire. Measurements Participants completed the self-reported question- naire which included general characteristics, the Parents’ Perception Uncertainty in illness Scale (PPUS), Personal Resource Questionnaire (PRQ), and the Parenting Stress Index–Short Form (PSI–SF). PPUS The original items of the PPUS (Mishel, 1983) were derived from Mishel’s Uncertainty in Illness Scale for Parenting Stress in Mothers of Children with CHD Asian Nursing Research ❖ September 2007 ❖ Vol 1 ❖ No 2 Adults (MUIS-A). The PPUS consists of 31 items and 4 subscales: ambiguity, lack of clarity, lack of information, and unpredictability. Ambiguity refers to the absence of cues or vagueness of cues concern- ing the planning and carrying out of care for the child. Lack of clarity refers to receiving or perceiv- ing information about the child’s treatment and the system of care as intricate and ill-defined. Lack of information relates to the absence of information concerning the diagnosis and seriousness of the ill- ness. Unpredictability refers to the inability to make daily or future predictions concerning symptom and illness outcome (Mishel, 1997). The PPUS is a 5- point Likert scale, and its score can range from 31 to 155, with a higher score indicating a higher level of uncertainty. After the researcher translated the PPUS into Korean, three professors evaluated and modi- fied it, and a bilingual person checked the meaning of each sentence by using reverse translation. The coefficient α for the PPUS was .91 in a study of 272 hospitalized children (Mishel, 1983), and the Cron- bach’s α score was .86 in this study. PRQ The PRQ was designed by Brandt and Weinert in 1981. The PRQ 82 was developed to measure situ- ational and perceived social support and it was upgraded to the PRQ 85, a self-administered tool, by Weinert in 1987. Part 1 of the PRQ 85 consists of 10 life situations in which an individual might be expected to need some assistance and provide infor- mation concerning the person’s resource and satis- faction with the help received from the resources. Part 2 of the PRQ 85 is a 25-item 7-point Likert scale that measures the respondent’s perceived level of social support. The PRQ 85 has four subscales: intimacy, social integration, worth, and assistance (Weinert). Scale scores range from 25 to 125, with a higher score indicating a higher level of perceived social support. The PRQ 85 translated by Suh and Oh (1993) was used in this study. In a study of 132 older persons living in trailer parks or mobile home settings, the internal consistency (Cronbach’s α) for the PRQ 85 was .87 (Weinert). We used Part 2 of the PRQ 85 and Cronbach’s α was .90. PSI–SF The PSI–SF was developed to evaluate parenting stress by Abidin in 1990, and the PSI–SF translated by Kim (1997) was used in this study.The PSI–SF has three subconcepts: parental distress, parent–child dysfunctional interaction, and difficult child. Parental distress determines the distress that a parent experi- ences in his/her role directly related to parenting. Parent–child dysfunctional interaction focuses on the parent’s perception that his/her child does not meet the parent’s expectation and that the interaction with his/her child reinforces dysfunctional interaction. Difficult child focuses on some of the basic behavioral characteristics of children that make them either easy or difficult to manage. The PSI–SF is a 35-item 5-point Likert scale, and its score ranges from 35 to 175, with a higher score indicating a higher level of parenting stress. Test–retest and alpha reliabilities for the PSI–SF were .84 and .91, respectively (Abidin, 1995). Cronbach’s α was .90 in this study. Data collection Approval of the institutional review board of the hospital was obtained prior to collecting data. A research assistant was familiarized with the goal of this study, the diagnosis of CHD, and the contents of the questionnaire. The research assistant then explained the goal of this study to the participants, obtained informed consent and then collected questionnaires at the pediatric cardiac outpatient clinic from July 14th to September 25th, 2006. The participants took about 20 minutes to complete the questionnaires. Data analysis Descriptive statistics were generated to describe the general characteristics of children with CHD and their mothers. Independent sample t test, ANOVA test, and Scheffé’s test were performed to identify differences in the level of parenting stress according to the general characteristics. Pearson’s correlation analyses were performed to examine the relation- ships among uncertainty, social support, and parent- ing stress. Multiple regression analysis was used to determine the factors affecting parenting stress. S.

Children’s characteristics There were 16 infants (31.4%), 17 toddlers (33.3%), 13 preschoolers (23.5%), and 6 school age children (11.8%). Thirty-five children (68.6%) reportedly had acyanotic cardiac anomalies and 16 children (31.4%) had cyanotic cardiac anomalies. Mothers’ characteristics Thirty-four (66.7%) mothers were full-time home makers and 17 (33.3%) mothers worked outside the home. Twenty-three (45.1%) mothers owned their house, 22 (43.1%) leased, and 6 (11.8%) rented their house. While 39 (76.5%) mothers obtained information from a health provider, close to one quarter of mothers (12) did not. Fourteen mothers (27.5%) reported that they obtained infor- mation on the Internet. Mothers’ parenting stress Table 2 shows the relationship between parenting stress and general characteristics. The mothers’ par- enting stress was significantly related to the chil- dren’s age (p < .01) and the mothers’ level of education (p = .03). Scheffé’s test showed that the mothers of school age children have a higher level of parenting stress than mothers of infants, toddlers and preschoolers. Mothers with higher educational level reported lower level of parenting stress. How- ever, parenting stress was not significantly related to the children’s cardiac anomalies. Relationships among uncertainty, social support, and parenting stress Correlation analysis found that uncertainty was sig- nificantly related to social support and parenting Table 1 General Characteristics (N = 51) n (%) Children’s characteristics Anomalies Acyanotic 35 (68.6) Cyanotic 16 (31.4) Age (years) < 1 (infant) 16 (31.4) 1–3 (toddler) 17 (33.3) 4–7 (preschooler) 13 (23.5) > 7 (school age) 6 (11.8) Gender Male 25 (49.0) Female 26 (51.0) Sibling Yes 34 (66.7) No 17 (33.3) Operation Yes 37 (72.5) No 14 (27.5) Mothers’ characteristics Age (years) 20–30 8 (15.7) 31–40 37 (72.5) > 40 6 (11.8) Education Middle school 3 (5.9) High school 21 (41.2) College and beyond 27 (52.9) Employment Home maker 34 (66.7) Working mother 17 (33.3) Housing Monthly rent 6 (11.8) Leasing house 22 (43.1) Own house 23 (45.1) Source of information Health provider Yes 39 (76.5) No 12 (23.5) Internet Yes 14 (27.5) No 37 (72.5) S.

The correlation coefficient of uncertainty and social support was –.477 (p < .01), and that of uncertainty and parenting stress was .463 (p < .01). Although the relationship between social support and parenting stress has already been reported in many previous studies, their relationship including uncertainty has not yet been studied. Therefore, an analysis of the relationships among social support, parenting stress, and subconcepts of uncertainty— ambiguity, lack of clarity, lack of information and unpredictability—was performed. Parenting stress was significantly related to social support, ambigu- ity, lack of clarity, and lack of information, but was not significantly related to unpredictability. As expected, mothers who reported higher ambiguity, less clarity, less information, and less social support demonstrated higher parenting stress. Unpre- dictability was not related to the other subconcepts of uncertainty and social support (Table 3). Factors affecting parenting stress Table 4 summarizes the results of multiple regression analysis. Included general variables were children’s age and mothers’ education. Since they were signif- icantly related to parenting stress in the prior analy- sis, sources of information, uncertainty and social support were also included in the analysis model. Social support and source of information via the Internet were statistically significant determinants of parenting stress in mothers of children with CHD. Social support explained 33.3% of parenting stress in this model, while social support and the source of information being the Internet together accounted for 39.4% of parenting stress. Therefore, mothers reported less parenting stress when they had more social support and obtained information via the Internet regardless of children’s age and mothers’ education. DISCUSSION According to the results of this study, parenting stress was significantly related to the children’s age. Particularly, mothers of school age children reported a higher level of uncertainty than mothers of infants, Table 3 Relationship Between Subconcepts Uncertainty and Parenting Stress Parenting Social Ambiguity Lack of Lack of Unpredictability stress support clarity information Parenting stress –.577* .455* .395* .379* .059 Social support –.536* –.294** –.389* .020 Ambiguity .719* .592* .065 Lack of clarity .524* .017 Lack of information .273 Unpredictability *p < .01; **p < .05.

This might be due to the fact that children with CHD have to deal with prob- lems related to school activities such as physical education classes. Horner, Liberthson, and Jellinek (2000) reported that about 50% of the subjects with CHD in their study were unable to participate fully, if at all, in organized or competitive sports. Children may also refuse to go to school or have difficult times adjusting to school because of other reasons. Future study is suggested to identify the fac- tors related to parenting stress in mothers of school age children with CHD. Correlation analyses showed that parenting stress was significantly related to social support. Aytch, Hammond, and White (2001) reported in their study of mothers of children with seizure disorder that many parents considered the opportunity to talk to other parents of children with the same disease help- ful because they can share child-rearing experiences. In addition to parent-to-parent support, the parents reported that family members (e.g., spouse, grand- parents, parent’s sibling), personal friends, and members of their church community were impor- tant sources of support. Ambiguity was significantly related to parenting stress. Ambiguity, which is a subconcept of uncer- tainty, refers to the absence of cues or vagueness of cues concerning the planning and carrying out of the care of the child (Mishel, 1997). In other words, ambiguity is lack of criteria for caring for the child. Mothers who did not have sufficient information regarding the care plan for their children reported a higher level of parenting stress. In general, health- care providers give information about children’s disease and medical and surgical management. But, mothers also want to know how to care for their child with CHD and how to prepare for emergency situations at home. Mothers of children with CHD are not only concerned about the symptoms of CHD, but also about children’s behaviors which are within the normal boundary of discipline. Mothers experience stress from being confused about the level of discipline for their children. Lack of clarity and lack of information, which are subconcepts of uncertainty, were also significantly related to parenting stress. Lack of clarity means insufficient knowledge about the treatment and treat- ment plan. Especially, mothers wanted to know the child’s treatment plan, for example, the schedule for echocardiogram, cardiac catheterization and opera- tion, as well as how often they should go to the hos- pital for follow-up. Mishel (1997) defined lack of information as the absence of information concern- ing the diagnosis and seriousness of illness. Chessa et al. (2005) reported that many parents of children with CHD do not understand the prognosis of their child’s disease. While the majority of parents could name the cardiac lesion and were knowledgeable concerning surgical and catheter interventions, their knowledge of the etiology and symptoms of CHD were limited. Furthermore, their knowledge about infective endocarditis and the side effects of cardiac medications appeared to be quite deficient (Cheuk, Wong, Choi, Chau, & Cheung, 2004). Interestingly, unpredictability—one of the subcon- cepts of uncertainty—was not significantly related to parenting stress and to other subconcepts of uncer- tainty.When a child was first diagnosed, uncertainty was a source of fear, anxiety and stress. Once mothers understand their child’s condition, they can develop the coping skills to adjust to their situation and have a new perspective in their lives (Mishel, 1990). Fur- thermore, parents’ anxiety may not be related to the severity of the child’s heart disease but to the parents’ individual coping style and fears (Clare, 1985). Even with high unpredictability, mothers can adapt to their situation and have hope for their children’s future. So, regardless of the predictability of the child’s disease, mothers’ coping skills are the impor- tant deciding factor. Thus, it is necessary to develop a nursing intervention for mothers of children with CHD that can cultivate effective coping skills. Multiple regression analysis showed that social support and information obtained from the Internet were significant determinants of the level of parent- ing stress. Parents used the Internet to communicate with other parents about their experiences as well as to obtain useful information. The need to commu- nicate with other parents who shared similar expe- riences and the desire to find information to gain a 123 better understanding of what was happening to their child were the primary motivating factors for using the Internet (Aytch, Hammond, & White, 2001). It is common for many parents in Korea to use the Inter- net to share their experiences and seek information about their child’s illness and behaviors. Using the Internet is not only helpful in getting practical infor- mation but also provides a channel to obtain social and emotional support from other parents with sim- ilar problems. However, some information from the Internet can be incorrect. Therefore, it is suggested that nurses actively participate in facilitating and monitoring such websites to provide accurate infor- mation. Further studies are suggested in this area. It is especially necessary to identify the specific factors that cause parenting stress at the different develop- mental ages of children with CHD. REFERENCES Abidin, R. R. (1990).
