The purpose of this study was to examine the relationship between family obligation and religiosity on the positive appraisal of caregiving among African-American, Hispanic and non-Hispanic Caucasian family caregivers of older adults. Roy’s adaptation model guided formulation of the aims and study design. A cross-sectional, correlational study design was employed to examine the relationship amongst variables for the family caregiver participants. Study participants (N ¼ 69) completed a demographic tool and four instruments the: (1) Katz index, (2) obligation scale, (3) Duke University religion index, and (4) positive appraisal of care scale. There was a significant correlation between family obligation and positive appraisal of caregiving. However, there was no relationship between the family caregiver’s religiosity and positive appraisal of caregiving overall. Demographic variables were also examined to show a higher marginal mean for Hispanic primary caregivers in relation to the positive appraisal of caregiving. Future studies should consider replicating these findings in a larger sample to provide health care professionals with substantial evidence to incorporate culturally sensitive interventions aimed at promoting positive outcomes and healthy family behaviors.

The United States (U.S.) is experiencing a rapid shift in population demographics that includes more AfricaneAmerican and Hispanic older adults.1 This increase impacts the number of culturally diverse family members caring for an older adult in the home. Projections indicate that the AfricaneAmerican older adults population will quadruple, and the Hispanic population of older adults will increase to 6.5 times its current size by 2050.1 There is now a demand for more research on the beneficial aspects of caregiving to better understand the possible antecedents that facilitate caregivers’ adaptation to the caregiver role among ethnic populations.2,3 There is a need to identify how ethnically diverse family members positively adapt to caregiving for an older adult family member. This article reports the results of a study that examined the relationship of cultural values of obligation and religiosity on the positive appraisal of caregiving of dependent older adults in family caregivers among AfricaneAmericans, Hispanics and non-Hispanic Caucasians. Providing care to a family member is a life-altering experience. Being a caregiver involves changes and sacrifices in order to meet the needs of the dependent older adult. This situation makes caregivers a vulnerable population.4 Caregiving is a multidimensional construct, which includes both positive and negative * Tel.: þ1 225 490 1639; fax: þ1 225 760 1760.

appraisal of the caregiving experience. For the purpose of this research, I focused on positive appraisal that elicits beneficial aspects, including feeling useful, adding meaning to sense of self, strengthening caregivers’ relationship with their relatives, and gaining satisfaction.3,5 Positive appraisal is important because the caregiver’s satisfaction, and finding gratification and meaning in their role as caregiver, influences the caregiver’s motivation for taking on, coping with and sustaining the ongoing responsibility in caring for another person.6 Positive appraisal may extend the length of time that family members are involved in care and delay or prevent the negative effects of caregiving on the family members’ health.6,7 Although normative expectations may influence positive appraisal, little is known about the influence of cultural norms of obligation and religiosity on the positive appraisal of caregiving. Culture is the values, beliefs, behaviors, artifacts and norms of a group that may guide the behavior of family members and their roles within the family.8 For example, within the construct of culture, a normative expectation may include familism. Familism refers to a strong identification and solidarity of individuals with their family, as well as strong normative feelings of allegiance, dedication, reciprocity and attachment to their family members.2 Familism influences a caregiver’s sense of obligation to provide care.4,9 Family obligation is the degree of a person’s expression for a cultural value that modifies the effect of caregiving appraisal and

perceived obligation to provide material and emotional support to the family.4,9 This sense of obligation to care is often overlooked when exploring ethnic caregivers’ positive appraisal of caregiving for dependent, older adult family members.4 Religious beliefs are connected to a family member’s motivation to provide care for frail older adults.10 Providing care for older adult family members is linked to religious values or more specifically, religiosity; one’s beliefs and practices related to a religious affiliation or to God.11,12 Religiosity reflects behaviors that include participation in religious activities (organizational), religious involvement (non-organizational) and subjective (intrinsic) reports of having a relationship with a higher being.11,13 Many religious belief systems foster a character of responsibility and care for others. This serves as an important resource when one is faced with the realities of responsibility and care and has been found to result in a positive outlook to caregiving.8,12,14 In a study of Africane American and non-Hispanic Caucasian family caregivers, Haley et al12 found that a relationship with a higher being, an increase in religious service attendance and a higher frequency of prayer significantly affected how AfricaneAmericans’ viewed and coped with the caregiver role. This was found to have a largely positive influence on their beliefs and perceptions of caregiving. Previous research supports religious coping as an internal resource used among AfricaneAmerican and Hispanic family caregivers.10,12,14 More specifically, research reports that organizational religiosity elicits a broad range of emotions to include positive or negative, a marker for a multidimensional experience.15 Research on AfricaneAmerican, Hispanic and non-Hispanic Caucasian positive appraisal of caregiving is limited. Due to the nation’s increasing diversity in older persons and their caregivers, it is important to better understand the impact of obligation and religiosity on family caregiving and caregiver appraisal.4 This study assessed the relationship of the cultural values of obligation and religiosity with the positive appraisal of caregiving among AfricaneAmerican, Hispanic and non-Hispanic Caucasians family caregivers for dependent, older adult family members. In order to explore the relationships among the variables, the following aims were addressed in this study: 1) describe obligation, religiosity and positive appraisal of caregiving among Africane American, Hispanic and non-Hispanic Caucasian family caregivers and 2) examine any differences in the relationships of obligation
127
and religiosity with positive appraisal of caregiving among Africane American, Hispanic and non-Hispanic Caucasian family caregivers. Based on these aims, the following null hypotheses were tested: 1) there were no differences among AfricaneAmerican, Hispanic and non-Hispanic Caucasian family caregivers in obligation, religiosity, and positive appraisal of caregiving; 2) obligation and religiosity were not associated with the positive appraisal of caregiving, after controlling for demographic characteristics to guard against confounding variables; and 3) there were no differences among AfricaneAmerican, Hispanic and non-Hispanic Caucasian family caregivers in the relationship of obligation and religiosity with positive appraisal of caregiving. Theoretical framework Roy’s adaptation model (RAM) was used as the theoretical framework to support this study (see Fig. 1). RAM, describes individuals as holistic adaptive systems that are capable of responding to internal and external environmental stimuli.16 The relatedness of study variables to Roy’s model guides the view of positive appraisal of caregiving as a continuous process of evaluating coping mechanisms to help re-establish stability between person and environment. AfricaneAmerican, Hispanic and nonHispanic Caucasian family caregivers, along with the independent variables of obligation and religiosity are affected directly by the stimuli of family caregiving, demographic and unknown variables. The phenomena of interest identified in RAM include the study of basic life processes and how nursing maintains adaptive responses or changes ineffective responses, which represents focal, contextual and residual stimuli.16 Focal stimuli, in this study, are represented by the family caregiving variable, which is the stimulus that immediately confronts the family. The demographic variables within this study represent the contextual stimuli, factors that contribute to family caregiving. Residual factors included in this study model are classified as unknown, as recommended by RAM,16 which allows for unknown environmental factors. Overall, the environmental stimuli examined the effect of independent variables upon the expected outcome of positive caregiver appraisal. The culturally relevant variables of obligation and religiosity are conceptualized as cognitive in nature, influencing family caregivers’ assessments of their roles as caregivers and are hypothesized to

influence their judgment of positive appraisal ultimately resulting in positive caregiver outcomes. The evaluation of obligation and religiosity on the positive appraisal of caregiving was examined among AfricaneAmerican, Hispanic and non-Hispanic Caucasian family caregivers. Methods Design A descriptive, cross-sectional survey design was used to explore the relationships of the cultural values of obligation and religiosity with the positive appraisal of caregiving among AfricaneAmerican, Hispanic and non-Hispanic Caucasian family caregivers. This design also was used to identify possible differences in the relationships of obligation, religiosity and positive appraisal of caregiving among the three racial/ethnic groups (henceforth, identified as ethnic groups). Sample The population for this study was AfricaneAmerican, Hispanic, and non-Hispanic Caucasian family caregivers of older adult family members from the Southeastern regions of Louisiana. In order to participate in this study, the following inclusion criteria were met: (1) individuals who identified themselves as either Africane American, Hispanic or non-Hispanic Caucasian; (2) 18 years of age or older; (3) individuals who were able to speak, write, read and understand the English language at the eighth grade level; (4) provision of a minimum of one activity of daily living according to the Katz index17 without financial reimbursement; and (5) at least 20 h per week of care to a noninstitutionalized family member who is over the age of 64 and has been diagnosed with a chronic illness. A non-probability purposive quota sampling technique, which is a type of convenience sampling technique, was used to ensure adequate numbers of subjects in each stratum for the planned statistical analysis.18 Quota sampling used in this study increases the representativeness of the sample by maintaining equal cell sizes for the planned statistical analysis, strategizing to ensure inclusion of subject types that are likely to be underrepresented. G*Power 3.119 calculated a sample size of 68 using a power of .80, medium effect size of r ¼ .15, and alpha of .05. An overall sample size of 69 was divided into three equal groups of 23 Africane Americans, Hispanics and non-Hispanic Caucasians family caregivers. The study was conducted in settings that family caregivers used. This included two adult day health care centers, five churches and one caregiver support group located in the greater New Orleans, River Parishes and Baton Rouge area in Louisiana. Instruments The following four instruments were used to screen participants and collect data in this study: (1) Katz index,17 (2) the obligation scale,20 (3) the Duke University religion index21 and (4) the positive appraisal of care scale.22 In addition, a demographic questionnaire was constructed to measure the caregiver’s age, gender, income, educational level, religion, caregiver type and relationship to older adult. Further age, gender and living arrangements of the care recipient were assessed. Katz index The Katz index of independence in activities of daily living ranks adequacy of performance in the six functions of bathing,
dressing, toileting, transferring, continence, and feeding by judging the degree of independence.17,23 Older adults were scored by a family caregiver as yes/no for independence in each of the six functions. A score of six indicated full function, four indicated moderate impairment, and two or less indicated severe functional impairment. The Katz index has been found to have reliability coefficients ranging from .87 to .94.24 The Katz index was used as a screening tool to determine dependency of the older adult. The obligation scale The obligation scale is a seven-item scale that measures general feelings to reflect cultural values about obligation to care for an older adult relative.20,25 Each item on the scale consist of a fivepoint Likert-type response that ranges from strongly agree (5) to strongly disagree (1). The respondents were asked to indicate how important each statement is as a reason for helping their family member with the higher score indicating higher obligation. Sample items included “I feel a sense of obligation to help”; “It’s a child’s duty to help”; and “I would feel ashamed if I didn’t help”. A higher score is associated with a greater feeling of family obligation. The reported internal consistency reliability was .71.25 This study paralleled Lee et al’s9 study which uses the obligation scale to assess the cultural values of caregivers. Duke University religion index The Duke University religion index (DUREL) is a five-item measure of religious involvement that assesses three major dimensions of religiosity: organizational (participation in religious activities), non-organizational (religious involvement in private activities), and intrinsic (having a relationship with a higher being) religiosity.21 The DUREL measures each of these dimensions by subscale to assess particular aspects of religious practice or religious devotion. Subscale number one is the first question in the DUREL that asks about frequency of attendance at religious services (organizational). Subscale number two is the second question that asks about frequency of private activities (non-organizational). Subscale number three consists of the final three items that assess intrinsic religiosity. A higher score indicates a greater sense of religiosity. The overall scale has had a high testeretest reliability (intra-class correlation) of .91 and a high convergent validity with other measures of religiosity (r’s ¼ .71e.86).13 Positive appraisal of care scale The positive appraisal of care scale was developed to evaluate positive appraisal of care among family caregivers within the framework of caregiver adaptation.22 This scale consists of 21 items: relationship satisfaction (five items), role confidence (five items), consequential gain (six items), and normative fulfillment (five items). Participants were instructed to rate “how you have been in the previous two weeks” using a four-point Likert scale. A higher score indicates a more positive appraisal of caregiving. YamamotoMitani et al22 reports Cronbach alphas of the domains and total scales as follows: .84 (relationship satisfaction), .83 (role confidence), .84 (consequential gain), .74 (normative fulfillment), and .92 (total of the positive appraisal of care scale). Procedure Written approval to conduct the study was obtained from the University Institutional Review Board (IRB), and each of the data collection sites according to the site’s research protocol. Written informed consent was obtained from all subjects. Flyers of the proposed study and how to contact the researcher to participate in

the study were posted among the facilities and sent home with care recipients, caregivers, and church members. Potential subjects were screened by telephone interview using the Katz index and demographic questionnaire. A total of 83 family caregivers were screened, with 69 caregivers meeting the inclusion criteria. Arrangements were made to meet with the caregivers for a one time interview at a convenient location to complete the remainder of the questionnaires. Data analysis Data were analyzed using the SPSS version 19 for Windows software. Descriptive statistics including frequency distributions, means, modes, medians, standard deviations, ranges and percentages were run to summarize variables. An analysis of variance (ANOVA) was used to test for differences in family obligation, religiosity, and positive appraisal of caregiving among Africane American, Hispanic and non-Hispanic Caucasian family caregivers. Multiple regression analysis also was used in a stepwise (hierarchical) fashion to evaluate the unique contributions of obligation and religiosity. This helped explain the variance in family caregivers’ positive appraisal of caregiving (among the three ethnic groups), after adjusting for demographic characteristics. Due to the small sample size, the regression model was built in stages to limit the number of independent variables used simultaneously.

The United States (U.S.) is experiencing a rapid shift in population demographics that includes more AfricaneAmerican and Hispanic older adults.1 This increase impacts the number of culturally diverse family members caring for an older adult in the home. Projections indicate that the AfricaneAmerican older adults population will quadruple, and the Hispanic population of older adults will increase to 6.5 times its current size by 2050.1 There is now a demand for more research on the beneficial aspects of caregiving to better understand the possible antecedents that facilitate caregivers’ adaptation to the caregiver role among ethnic populations.2,3 There is a need to identify how ethnically diverse family members positively adapt to caregiving for an older adult family member. This article reports the results of a study that examined the relationship of cultural values of obligation and religiosity on the positive appraisal of caregiving of dependent older adults in family caregivers among AfricaneAmericans, Hispanics and non-Hispanic Caucasians.

appraisal of the caregiving experience. For the purpose of this research, I focused on positive appraisal that elicits beneficial aspects, including feeling useful, adding meaning to sense of self, strengthening caregivers’ relationship with their relatives, and gaining satisfaction.3,5 Positive appraisal is important because the caregiver’s satisfaction, and finding gratification and meaning in their role as caregiver, influences the caregiver’s motivation for taking on, coping with and sustaining the ongoing responsibility in caring for another person.6 Positive appraisal may extend the length of time that family members are involved in care and delay or prevent the negative effects of caregiving on the family members’ health.6,7 Although normative expectations may influence positive appraisal, little is known about the influence of cultural norms of obligation and religiosity on the positive appraisal of caregiving. Culture is the values, beliefs, behaviors, artifacts and norms of a group that may guide the behavior of family members and their roles within the family.8 For example, within the construct of culture, a normative expectation may include familism. Familism refers to a strong identification and solidarity of individuals with their family, as well as strong normative feelings of allegiance, dedication, reciprocity and attachment to their family members.2 Familism influences a caregiver’s sense of obligation to provide care.4,9 Family obligation is the degree of a person’s expression for a cultural value that modifies the effect of caregiving appraisal and

perceived obligation to provide material and emotional support to the family.4,9 This sense of obligation to care is often overlooked when exploring ethnic caregivers’ positive appraisal of caregiving for dependent, older adult family members.4 Religious beliefs are connected to a family member’s motivation to provide care for frail older adults.10 Providing care for older adult family members is linked to religious values or more specifically, religiosity; one’s beliefs and practices related to a religious affiliation or to God.11,12 Religiosity reflects behaviors that include participation in religious activities (organizational), religious involvement (non-organizational) and subjective (intrinsic) reports of having a relationship with a higher being.11,13 Many religious belief systems foster a character of responsibility and care for others. This serves as an important resource when one is faced with the realities of responsibility and care and has been found to result in a positive outlook to caregiving.8,12,14 In a study of Africane American and non-Hispanic Caucasian family caregivers, Haley et al12 found that a relationship with a higher being, an increase in religious service attendance and a higher frequency of prayer significantly affected how AfricaneAmericans’ viewed and coped with the caregiver role. This was found to have a largely positive influence on their beliefs and perceptions of caregiving. Previous research supports religious coping as an internal resource used among AfricaneAmerican and Hispanic family caregivers.10,12,14 More specifically, research reports that organizational religiosity elicits a broad range of emotions to include positive or negative, a marker for a multidimensional experience.15 Research on AfricaneAmerican, Hispanic and non-Hispanic Caucasian positive appraisal of caregiving is limited. Due to the nation’s increasing diversity in older persons and their caregivers, it is important to better understand the impact of obligation and religiosity on family caregiving and caregiver appraisal.4 This study assessed the relationship of the cultural values of obligation and religiosity with the positive appraisal of caregiving among AfricaneAmerican, Hispanic and non-Hispanic Caucasians family caregivers for dependent, older adult family members.

influence their judgment of positive appraisal ultimately resulting in positive caregiver outcomes. The evaluation of obligation and religiosity on the positive appraisal of caregiving was examined among AfricaneAmerican, Hispanic and non-Hispanic Caucasian family caregivers. Methods Design A descriptive, cross-sectional survey design was used to explore the relationships of the cultural values of obligation and religiosity with the positive appraisal of caregiving among AfricaneAmerican, Hispanic and non-Hispanic Caucasian family caregivers. This design also was used to identify possible differences in the relationships of obligation, religiosity and positive appraisal of caregiving among the three racial/ethnic groups (henceforth, identified as ethnic groups). Sample The population for this study was AfricaneAmerican, Hispanic, and non-Hispanic Caucasian family caregivers of older adult family members from the Southeastern regions of Louisiana. In order to participate in this study, the following inclusion criteria were met: (1) individuals who identified themselves as either Africane American, Hispanic or non-Hispanic Caucasian; (2) 18 years of age or older; (3) individuals who were able to speak, write, read and understand the English language at the eighth grade level; (4) provision of a minimum of one activity of daily living according to the Katz index17 without financial reimbursement; and (5) at least 20 h per week of care to a noninstitutionalized family member who is over the age of 64 and has been diagnosed with a chronic illness. A non-probability purposive quota sampling technique, which is a type of convenience sampling technique, was used to ensure adequate numbers of subjects in each stratum for the planned statistical analysis.18 Quota sampling used in this study increases the representativeness of the sample by maintaining equal cell sizes for the planned statistical analysis, strategizing to ensure inclusion of subject types that are likely to be underrepresented. G*Power 3.119 calculated a sample size of 68 using a power of .80, medium effect size of r ¼ .15, and alpha of .05. An overall sample size of 69 was divided into three equal groups of 23 Africane Americans, Hispanics and non-Hispanic Caucasians family caregivers. The study was conducted in settings that family caregivers used. This included two adult day health care centers, five churches and one caregiver support group located in the greater New Orleans, River Parishes and Baton Rouge area in Louisiana. Instruments The following four instruments were used to screen participants and collect data in this study: (1) Katz index,17 (2) the obligation scale,20 (3) the Duke University religion index21 and (4) the positive appraisal of care scale.22 In addition, a demographic questionnaire was constructed to measure the caregiver’s age, gender, income, educational level, religion, caregiver type and relationship to older adult. Further age, gender and living arrangements of the care recipient were assessed. Katz index The Katz index of independence in activities of daily living ranks adequacy of performance in the six functions of bathing,
dressing, toileting, transferring, continence, and feeding by judging the degree of independence.17,23 Older adults were scored by a family caregiver as yes/no for independence in each of the six functions. A score of six indicated full function, four indicated moderate impairment, and two or less indicated severe functional impairment. The Katz index has been found to have reliability coefficients ranging from .87 to .94.24 The Katz index was used as a screening tool to determine dependency of the older adult. The obligation scale The obligation scale is a seven-item scale that measures general feelings to reflect cultural values about obligation to care for an older adult relative.20,25 Each item on the scale consist of a fivepoint Likert-type response that ranges from strongly agree (5) to strongly disagree (1). The respondents were asked to indicate how important each statement is as a reason for helping their family member with the higher score indicating higher obligation. Sample items included “I feel a sense of obligation to help”; “It’s a child’s duty to help”; and “I would feel ashamed if I didn’t help”. A higher score is associated with a greater feeling of family obligation. The reported internal consistency reliability was .71.25 This study paralleled Lee et al’s9 study which uses the obligation scale to assess the cultural values of caregivers. Duke University religion index The Duke University religion index (DUREL) is a five-item measure of religious involvement that assesses three major dimensions of religiosity: organizational (participation in religious activities), non-organizational (religious involvement in private activities), and intrinsic (having a relationship with a higher being) religiosity.21 The DUREL measures each of these dimensions by subscale to assess particular aspects of religious practice or religious devotion. Subscale number one is the first question in the DUREL that asks about frequency of attendance at religious services (organizational). Subscale number two is the second question that asks about frequency of private activities (non-organizational). Subscale number three consists of the final three items that assess intrinsic religiosity. A higher score indicates a greater sense of religiosity. The overall scale has had a high testeretest reliability (intra-class correlation) of .91 and a high convergent validity with other measures of religiosity (r’s ¼ .71e.86).13 Positive appraisal of care scale The positive appraisal of care scale was developed to evaluate positive appraisal of care among family caregivers within the framework of caregiver adaptation.22 This scale consists of 21 items: relationship satisfaction (five items), role confidence (five items), consequential gain (six items), and normative fulfillment (five items). Participants were instructed to rate “how you have been in the previous two weeks” using a four-point Likert scale. A higher score indicates a more positive appraisal of caregiving. YamamotoMitani et al22 reports Cronbach alphas of the domains and total scales as follows: .84 (relationship satisfaction), .83 (role confidence), .84 (consequential gain), .74 (normative fulfillment), and .92 (total of the positive appraisal of care scale). Procedure Written approval to conduct the study was obtained from the University Institutional Review Board (IRB), and each of the data collection sites according to the site’s research protocol. Written informed consent was obtained from all subjects. Flyers of the proposed study and how to contact the researcher to participate in

the study were posted among the facilities and sent home with care recipients, caregivers, and church members. Potential subjects were screened by telephone interview using the Katz index and demographic questionnaire. A total of 83 family caregivers were screened, with 69 caregivers meeting the inclusion criteria. Arrangements were made to meet with the caregivers for a one time interview at a convenient location to complete the remainder of the questionnaires. Data analysis Data were analyzed using the SPSS version 19 for Windows software. Descriptive statistics including frequency distributions, means, modes, medians, standard deviations, ranges and percentages were run to summarize variables. An analysis of variance (ANOVA) was used to test for differences in family obligation, religiosity, and positive appraisal of caregiving among Africane American, Hispanic and non-Hispanic Caucasian family caregivers. Multiple regression analysis also was used in a stepwise (hierarchical) fashion to evaluate the unique contributions of obligation and religiosity. This helped explain the variance in family caregivers’ positive appraisal of caregiving (among the three ethnic groups), after adjusting for demographic characteristics. Due to the small sample size, the regression model was built in stages to limit the number of independent variables used simultaneously. Following the recommendations of Mickey and Greenland26 for the screening of covariates individually, only demographic characteristics that had a bivariate association with positive appraisal with a p value 76,000 Religion Baptist Catholic Methodist Non-denominational Pentecostal Relationship Child Grandchild Sibling Spouse Niece/nephew Caregiver type Primary Secondary
