Perceived Effectiveness of Elder Abuse Interventions in Psychological Distress and the Design of Culturally Adapted Interventions: A Qualitative Study in the Chinese Community in Chicago
This qualitative study examines US Chinese older adults’ views on the perceived effectiveness, challenges, and cultural adaptations of elder abuse interventions to psychological distress in the Chinese community in Chicago. A community-based participatory research approach was implemented to partner with the Chinese community. A total of 37 community-dwelling Chinese older adults (age 60+) participated in focus group discussions. Data analysis was based on grounded theory framework. Our findings suggest that older adults perceived social support, empowerment, and community-based interventions design as most effective to promote psychological well-being of victims. The perceived preferences were similar between elder abuse victims and non-victims. Strategies to culturally adapt evidence-based interventions were proposed with respect to nurturing filial piety values, familial integrations, and increased independence. Research and educational outreach initiatives were also discussed. This study has wide policy and practice implications for designing and deploying interventions to reduce psychological distress with respect to elder abuse outcome. Cultural relevancy of health interventions is important in the context of the Chinese communities. Collective federal, state, and community efforts are needed to support the culturally appropriate design and implementation of interventions suitable for the needs of the Chinese older adults.
Elder abuse, sometimes referred to as elder mistreatment or elder maltreatment, is an important global health issue. Elder abuse manifests in various forms including physical abuse, sexual abuse, psychological abuse, caregiver neglect, and financial exploitation . Available data suggest that 10% of US older adults aged 60 or older experience one or multiple forms of abuse [2, 3]. Despite the accessibility of Adult Protective Services in all fifty states, an overwhelming number of abused older adults may pass through healthcare system undiagnosed and overlooked. Associated with increased risk of morbidity and mortality, elder abuse continues to affect the quality of lives among vulnerable older adults [4–7]. Of particular importance is the adverse health outcome of elder abuse on victims’ psychological well-being. Abused older adults exhibit symptoms of depression, anxiety, fear, and unworthiness, amongst other forms of psychological distress .
The associations between elder abuse and psychological distress highlight the urgent need for developing intervention programs addressing both elder abuse and psychopathology. Even though elder abuse has great public health relevance to health care professionals, social services providers, and the community gatekeepers and leaders, we have incomplete understanding of evidence-based prevention and intervention strategies to assist victims of elder abuse [9, 10]. A number of studies have started to examine the effectiveness of different intervention programs to reduce psychological distress, including increased social support for both victims and perpetrators [11–13], victim empowerment , advocacy interventions [14–16], and cognitive behavior activation . However, research on interventions to reduce psychological distress with respect to elder abuse outcome remains scarce . A recent systematic review further reported that existing interventions had limited effects on improving the social and psychological well-being of victims .
In addition, there exist structural, cultural, and social barriers in help seeking among the victims. For elder abuse victims, barriers to obtaining services may include physical frailty, cognitive impairment, and dependence on the abusers . At the same time, victims may also serve in a caregiving or support capacity to their dependents or abusive family members, which in turn create different but equally challenging barriers to the victims’ willingness and acceptance of needed services for themselves . The issue of cultural diversity surrounding elder abuse further exemplifies a major complexity in advancing the field of elder abuse intervention. There exist knowledge gaps in understanding the cultural complexities of effective psychological well-being care supporting victims of elder abuse, particularly for minority older adults including African, Hispanic, and Asian populations .
Chinese population is one of the fastest growing minority groups in the U.S. Population estimates suggest that there are 4.0 million Chinese Americans in the United States, comprising 23% of the Asian American. Much of the health concern of Chinese older adults is deeply related to family caregiving guided by filial piety virtues. In Confucius teachings, filial piety dictates children’s obligatory roles and responsibilities of caregiving to aging parents [22, 23]. Whereas respect for seniors is a deep-rooted cultural tradition, recent research suggests that elder abuse is an existing and pervasive health issue facing U.S. Chinese older adults [5, 24]. However, we are unaware of any studies that have examined the perceptions and preferred programs to reduce psychological distress from the perspectives of community-dwelling Chinese American older adults. Improved understanding of important factors shaping effective care for older adults’ psychological well-being brings significant implications for health care professionals, social services providers, and health policy makers.
In order to expand our knowledge base on elder abuse interventions in a community-dwelling population of Chinese older adults, the goals of this qualitative study were to (1) elicit the perceived effectiveness of elder abuse interventions in reducing psychological distress, (2) explore similarities and differences in intervention preferences between the victim group and nonvictim group, and (3) identify strategies to culturally adapt evidence-based intervention programs to reduce psychological distress in the Chinese aging population.
2.1. Conceptual Framework and Definition
This study followed the conceptual framework of sociocultural context of elder abuse suggested by the National Research Council . In this framework, elder abuse is defined as “intentional actions that cause harm or create a serious risk of harm (whether or not harm is intended) to a vulnerable elder by a caregiver or other person who stands in a trust relationship to the elder; or failure by a caregiver to satisfy the elder’s basic needs or to protect the elder from harm.” The Socio-Cultural Context model focuses on the comprehensive assessment of vulnerability factors while considering the socio-cultural context and social embeddedness, which refers to the set of people in the social network between older adult and trusted others. It is the interactions among these components in which elder abuse may take place, while at the same time guiding the proposed analysis in this report.
2.2. Community-Based Participatory Research Approach
Community-based participatory research (CBPR) design has been reported as an important model for exploring the issues of elder abuse in minority communities [25, 26]. Described as “a systematic inquiry with the participation of those affected by the issue being studied, for the purpose of education and taking action or affecting social change” , CBPR allows researchers, community leaders, stakeholders, and members alike to form a synergistic collaboration for community changes. In order to fully engage Chinese community through the preparation, conduct, and findings dissemination of research processes, a community-academic collaboration was formed between Rush University Medical Center and Chinese American Service League (CASL), the oldest and largest social service agency dedicated to serving Chinese immigrants in the Midwest. In order to maximize cultural and linguistic sensitivity of our research efforts, we formed a community advisory board to provide overall guidance ranging from research conceptualization and preparation to the conduct and findings review . Board members were stakeholders and leaders enlisted through civic, health, social and advocacy groups, community centers, and clinics. Residents and opinion leaders were also invited to join the bimonthly meetings.
Since the inception of this synergistic community-academic collaboration, elder abuse has been identified as a pervasive health issue facing the Chinese community. A number of initiatives were undertaken to improve our understandings in this complex public health concern. We investigated cultural perception of elder abuse in the Chinese community through focus group discussions and in-depth interviews [5–7]. A recent advocacy effort also included the commemoration of the World Elder Abuse Awareness Day (WEAAD). Proclaimed by President Obama, WEAAD is now observed every year on June 15 in the U.S. as the opportunity to learn the signs of elder abuse and to empower older adults with tools and information necessary to overcome abusive situations . The Chicago community commemorated WEAAD for the first time in CASL. Residents were invited to join focus group discussions regarding their views on elder abuse interventions. All study procedures were approved by the Rush University Medical Center Institutional Review Board.
2.3. Study Design and Procedure
This study utilizes both survey questionnaires and semistructured focus group methods to investigate the experience of elder abuse among U.S. Chinese older adults. We invited seniors who experienced elder abuse as well as those who did not experience elder abuse to participate. Our sample size was 37. In order to ensure diverse opinions, we planned to recruit one-third of elder abuse victims and two-thirds of nonvictims in the study sample.
Elder abuse was measured using a self-reported instrument derived from the Hwalek-Sengstok Elder Abuse Screening Test (H-S/EAST) and the Vulnerability to Abuse Screening Scale (VASS) (Hwalek and Sengstock, 1986; Schofield and Mishra, 2003). Sample questions included if participants felt uncomfortable with someone in the family, have been called names or put down, or been forced by someone to do things their belongings without have been taken permission. In addition, basic sociodemographic information was collected, including age, sex, education, marital status, household, country of origin, years of residing in the U.S. and preferred language.
Participants were then invited to participate in semistructured focus group discussions. Health behavior and interventions are highly culturally mediated issues. Focus group technique is an important qualitative research technique. It is particularly well suited for an exploratory study for which previous health literature is limited and for generating hypotheses and models of human behavior . Focus group participants were recruited in accordance with the following eligibility criteria: (1) aged sixty years or older, (2) self-identified as Chinese, and (3) reside in Chicago. Prior to survey questionnaires and focus group discussions, study participants gave written consents. All materials were prepared in simplified Chinese, traditional Chinese, and English. In order to ensure cultural sensitivity of the study, participants were then divided into four focus groups according to their preferred dialect, including Cantonese or Mandarin . Focus group interviews were guided by trained facilitators affiliated with CASL. Participants’ perception of elder abuse interventions, perceived barriers, and facilitators of intervention programs were explored by the following questions.(1)In general, what components in elder abuse interventions will be most effective to reduce psychological distress of abused seniors in our community?(2)What components or approach in elder abuse interventions will probably not work in reducing psychological distress of abused seniors in our community?(3)What are the creative ways or measures you can think of to improve the interventions components?(4)How do we overcome these challenges to promote intervention programs in accordance with Chinese cultural and linguistic contexts?
The length of discussions was determined by the levels of interaction among participants. The facilitators proceeded with topics when responses were exhausted.
2.4. Data Analysis
For analysis purpose, we performed descriptive statistical analysis based on survey results. In accord with the standard diagnosis of a positive screen, the screening was considered positive for elder abuse or neglect if a patient answered yes to any of the screening questions.
With respect to qualitative data, grounded theory provided a general framework to analyze and develop themes and theories [31–33]. A bilingual research assistant first transcribed audio recordings into Chinese transcripts (different dialects used the same Chinese characters). The original Chinese transcripts were then imported into NVivo software (NVivo, version 9) for analysis. Two bicultural and bilingual researchers analyzed data in Chinese iteratively. Following grounded theory, they first labeled the texts with key words and phrases. The key words were coded and analyzed for emerging categories. Two coders then compared and discussed their sets of categories collectively to evolve dominant themes. The categorization of each response was not finalized until consensus was reached. Each category was reviewed and a short summary was written for each category. Quotes from the Chinese transcripts that captured participants’ opinions and sentiments were then translated into English and incorporated to support each theme. The essence of discussions could be truly captured by working with the original language in which the focus groups took place.
3.1. Characteristics of the Study Population by the Presence of Abuse
A total of 37 participants enrolled in the project (Table 1). Among these, 11 participants (29.7%) reported at least one item in the abuse screening tool in the domain of psychological, physical, financial abuse and exploitation. There were more men than women who screened positive for abuse. In the victim group, the majority (72.7%) were married and received 0–8 years of education (36.4%) or 13 or more years of education (36.4%). All of the participants who screened positive to abuse emigrated from Mainland China.
3.2. Perceived Effectiveness of Elder Abuse Interventions
We explored the perceived effectiveness of elder abuse interventions in reducing psychological distress using open-ended questions. Intervention programs identified as most effective to least effective included social support, empowerment, community-based interventions, advocacy, and psychological interventions (Table 2).
Of all the dimensions identified, the majority of responses fell into the category of social support. Specifically, increased peer group support, family support, and community support were viewed as beneficial elements to reduce distress of abused victims. For instance, support group that reduces social isolation and further informs seniors of their rights may be helpful to victims. As one participant described, “If you have a speaker that experienced elder abuse to come in and actually talk to the elders, then elders can connect with someone who understands what they are going through”.
Empowerment was identified as an effective process to help individuals maximize their confidence, skills, and abilities in order to regain control of their lives. Many participants perceived education as the first step to inform victims of their rights. In addition, participants also pointed to increased financial independence of victims as an initial step. Many participants held favorable views toward interventions delivered by community-based social services organizations. Community-based organizations that offer bilingual and bicultural services have been viewed as a safe haven by immigrant older adults and perceived as the only available help resource for immigrants [5–7]. Participants perceived the easy access, prompt response, and flexibility to integrate interventions into existing programs as a plus to community-based intervention module. Advocacy and psychological intervention garnered least favorable views from our data analysis.
3.3. Similarities and Differences on Perceptions of Intervention Component between Victims and Nonvictims Groups
In addition, this study investigated the similarities and differences regarding preferences on the intervention components between the victims and nonvictims (Table 3). The majority of responses on preferred intervention programs from victims fell into community-based interventions and empowerment, whereas for nonvictim respondents, empowerment, and social support components received the most favorable views. Psychological interventions, including behavioral interventions and behavioral activations, remained least favorable by both groups.
3.4. Perceived Challenges to Each Intervention Component
This study also captured the potential challenges in the design of interventions from the perspectives of older adults (Table 4). A most commonly perceived challenge to advocacy pertains to the fear of limited actions. Participants expressed that advocacy programs would not be effective if the design and implementation only set out to enhance victim self-care without actionable goals. Advocacy could easily be interpreted as “knowledge” or “a type of explanation to abusive situations” and thus may be rendered less effective. Furthermore, participants were aware of the potential implementation barriers to other programs, such as empowerment and psychological interventions. Participants commented that empowerment programs would only be helpful if linking with other elements, such as counseling or peer group support element, that is empowerment does not work; if victims are not provided with direct counseling help (and support), then nothing can be resolved”.
The benefits of psychological interventions to reduce psychological distress of victims remained least evident throughout the discussion. We suspect that the concept of behavioral activation or cognitive behavioral therapy may be foreign to community-dwelling older adults; hence there exists limited understanding on its benefits. Participants expressed the major challenge pertaining to negative perceptions on psychological interventions and behavior interventions. There may be a high level of reluctance and shame in joining such interventions.
Last, many seniors perceive intervention as a way to advocate for victims and their family members that “the community has to do something about it to provide them (victims) the protection and care that they deserve”.
3.5. Strategies to Culturally Adapt Elder Abuse Interventions in Chinese Communities
In light of the perceived challenges in the design of interventions, we also solicited ways to adapt existing elder abuse interventions for Chinese seniors in accordance with Chinese cultural and linguistic characteristics (Table 5). Most of the responses fell in the category of improving filial piety practice as a way to improve social support. As one participant claimed, “Parents will feel much better if their children are filial. This is the best measure to help seniors”. The importance of educating and nurturing filial piety values was echoed throughout the discussions.
In addition, our analysis showed that improved peer support by organizing community social events and activities may be a viable option to increase cultural sensitivity of intervention programs. One participant proposed that support group discussions may be integrated with existing cultural programs offered by community centers. Participants also called for more research and educational outreach efforts Health surveys were perceived as a helpful way to equip older adults with necessary health sciences knowledge. In addition, rigorous research contributes to the identification of seniors at high risks of abuse as well as those “who need the most help from us”. Last, increasing religious involvement was recognized as a helpful strategy. Participants linked religious attendance with increased social support, and thus it may be an effective intervention for victims.
In this first exploratory study of perceived effectiveness, challenges, and cultural adaptations of elder abuse interventions among community-dwelling Chinese older adults, our findings suggest that older adults viewed social support, empowerment, and community-based interventions design as most effective to vulnerable victims. The preferences were similar between victim and nonvictims. Strategies to tailor interventions toward Chinese cultural beliefs were also proposed with respect to nurturing filial piety values, familial integration, and improving independence of victims.
This qualitative investigation provides new insights on how minority older adults viewed different abuse intervention components and strategies to overcome intervention barriers. First, our findings provide direction for violence-related intervention services. A multidisciplinary approach that includes strengthening the informal support system including family members, friends, and community gatekeepers as well as facilitating access to formal services building on the health care system warrants exploration in this context.
It has been argued that older adults with fewer psychosocial resources or more psychosocial deficits seem to be more vulnerable to elder abuse, and elder abuse seems particularly detrimental to psychological well-being for victims . Our data suggest that the increased social support from family, friends, and supports is viewed as amongst the most effective interventions in increasing psychosocial resources of victims. This finding resonates with respect to important Chinese traditional values of filial obligations of respect and care from older adults. Despite acculturation challenges brought about by immigration, many traditional values and practices are still entrenched in this community. The utilization of family power in intervention designs warrants further attention.
It is also worth noting that advocacy and psychological interventions received limited appraisal among participants. Advocacy programs aim to enhance abused victims’ self-care by helping them to make sense of the situation, identify potential solutions, and achieve the goals they have set . From the limited empirical evidence, the effect of advocacy intervention designed to improve quality of life and mental health of Chinese abused women remained to be seen [14–16]. Similarly, whereas cognitive behavior model remained less favorable, some researches suggest that it can be a viable model in Chinese American population, with a few modifications [35, 36]. Systematic research is needed to explore the effectiveness of the different components of the advocacy and psychological intervention for the various forms of elder abuse.
In addition, given that community-based intervention module is appraised by Chinese older adults in this study, future research is needed to move forward to designing multicomponent elements of interventions suitable for the needs of minority older adults. For instance, studies in tribal communities found that interventions that offer combinations of individual or family counseling, case management, skills training, and behavior management strategies may be more effective than interventions that only provide a peer support group . Measures that provide the opportunity for older adults, caregivers, families, and health professionals to come together to prevent and mitigate elder abuse in a community setting may be a novel option for Chinese older adults.
Furthermore, the results highlight the need to alleviate older adults’ fears and shame in disclosing abuse. Our findings reveal that there exist more similarities than differences in the preferences of intervention programs between susceptible victims and nonvictims. Although the finding may be due to a small sample size effect, the violence and mental health stigma may indeed affect older adults’ willingness to enroll in intervention programs. Health care providers should consider outreach programs particularly designed to reduce the stigma of violence and caregiver stress among Chinese immigrant families.
Last, conducting participatory research approach allows us to prioritize sensitive cultural context and increase the relevance of our research findings to actionable intervention goals [38, 39]. When culture is continually evolving, the ability to identify factors that are amendable to adaptation to the Chinese population would help ensure that the health intervention is sensitive to the needs and concerns of victims. Our synergetic academic-community collaboration helps raise awareness and understanding of the complexities in elder abuse situations and further empower older adults and their family members.
There are several limitations to this study. First, the data used in this investigation were from a small sample of Chinese older adults. Future studies should consider working with diverse Chinese immigrants in a population-based study design. Second, the sample used was purposively selected from the Chinese community in Chicago, and hence, our results may not be generalizable to other Chinese populations, including suburban groups, Chinese ethnic minority groups, or rural Chinese populations, as they may be subjected to varying degrees of social and economic influence . Systematic examinations of the longitudinal risk and protective factors and of effect size are needed to devise targeted intervention studies. In addition, given the extent of the different types of elder abuse and variation in risk and protective factors and perpetrator characteristics, we did not investigate evidence-based interventions for the specific dyads that may be at particularly high risk for elder abuse. Rigorously designed intervention studies and measures of relevant outcomes of elder abuse are particularly needed.
Nonetheless, this study provides insights on the policy and practice implications for designing and deploying intervention to reduce psychological distress with respect to elder abuse outcome in Chinese aging communities. Cultural relevancy of health interventions is critical in this vulnerable population. Cultural sensitivity in health intervention programs entails more than matching languages or locations preferred by the local community members. Rather, incorporating the cultural, social, and structural contexts in the targeted community contributes to the salience of policy impact [41, 42]. In addition, health care professionals should consider outreach programs particularly designed to increase familial, social, and community support for vulnerable older adults. Collective federal, state, and community efforts are needed to support the culturally appropriate training and education on elder abuse interventions.
We conclude that, from the perspectives of community-dwelling Chinese older adults, elder abuse interventions hold promise for improving the psychological well-being of victims. Our results further underscore the urgent need of designing culturally and linguistically sensitive evidence-based interventions tailored toward the needs of diverse aging populations.
