Abstract
Introduction:
Grief among mothers of children with cerebral palsy (CP) has primarily been examined as caregiver burden, with limited attention to its cultural and moral meanings. This study explored culturally embedded experiences of grief among mothers in Northeast Thailand.
Methods:
A qualitative study using an inductive thematic analysis approach was conducted with 25 mothers who were primary caregivers of children with CP. Participants were purposively recruited through a provincial special education center and community gatekeepers. Data were collected through semi-structured interviews in the Isan dialect, transcribed, translated, and analyzed until thematic saturation was achieved.
Results:
Three themes emerged: disrupted life trajectory, continuous caregiving as lived loss, and meaning-making through relational and cultural resources, including Xiow, karma, and Kong Sibsi. Although many mothers found acceptance, some reported distress.
Discussion:
Grief is an ongoing, culturally mediated process. Culturally congruent approaches that integrate relational and spiritual dimensions may enhance support for caregiving mothers.
Introduction
Grief among mothers of children with cerebral palsy (CP) has largely been examined in relation to caregiver burden, psychological distress, and chronic sorrow (Fouad et al., 2022; M. Smith & Blamires, 2022; Zahl et al., 2024). While these perspectives have contributed to understanding caregiving challenges, they often overlook the cultural, moral, and existential meanings through which grief is experienced and interpreted (Dlamini et al., 2023; Neimeyer, 2019; Park, 2022). In this study, grief is understood as a multidimensional and evolving response to the loss of an anticipated life trajectory, distinct from, yet potentially coexisting with, related constructs such as caregiver burden, depression, stress, chronic sorrow, anticipatory grief, and ambiguous loss (Boss, 2006; Stroebe & Schut, 2010; Yehene et al., 2021).
In Thailand, particularly in the Northeastern (Isan) region, caregiving is embedded within relational, moral, and spiritual frameworks that shape how grief is understood and managed. Buddhist beliefs, including karma, provide an interpretive lens through which suffering is contextualized, while moral teachings such as Kong Sibsi (the 14 moral rules) emphasize patience, compassion, and social responsibility in everyday life (Aulino, 2019; Bancha et al., 2023; Punaglom et al., 2022; Sethabouppha & Kane, 2005). In addition, culturally specific relational practices such as Xiow—a sworn friendship bond characterized by enduring mutual support and a strong sense of commitment—reflect broader values of interconnectedness and collective care (Ratsamee, 2025; Thiengtham et al., 2024).
Despite increasing recognition of caregiving challenges among mothers of children with CP (Celik & Kaya, 2024; M. Smith & Blamires, 2022; Uddin & Ashrafun, 2023), limited research has examined how grief is culturally constructed and negotiated within Thai or Isan contexts. Existing studies have largely focused on burden and coping, with less attention to the moral and relational dimensions that shape meaning-making processes (Dlamini et al., 2023; Liu et al., 2023). This gap is particularly important in settings where cultural beliefs and social relationships play a central role in caregiving experiences (Aulino, 2019; Sethabouppha & Kane, 2005).
This study aimed to explore the cultural meanings and lived experiences of grief among mothers caring for children with CP in Northeast Thailand, with particular attention to how grief is interpreted and sustained within culturally embedded relational and spiritual frameworks.
Methods
Ethical Considerations
This study was conducted in accordance with established ethical principles for research involving human participants and adhered to the Consolidated Criteria for Reporting Qualitative Research (Tong et al., 2007). Ethical approval was obtained from the Institutional Review Board of Nakhon Phanom University (Approval No. HE2868). The study underwent a full board review process due to the involvement of potentially vulnerable participants and the sensitive nature of the research topic.
Participants were informed about the study purpose, procedures, and their rights, including voluntary participation and the ability to withdraw at any time without consequences. Written informed consent was obtained prior to data collection. All data were anonymized, and identifying information was removed during transcription and analysis. Interviews were conducted with careful attention to participants’ emotional well-being, and participants were able to pause or decline to answer any questions.
Study Design
A qualitative descriptive design with interpretive elements was employed (Turale, 2020), guided by a constructivist perspective (B. Smith & Sparkes, 2020). An inductive thematic approach, as outlined by Braun and Clarke (2006), was used to explore how grief is experienced and meaningfully constructed within specific cultural and spiritual contexts among mothers caring for children with CP in Northeast Thailand.
Participants and Sampling
Participants were mothers recruited through a registry of 65 children diagnosed with CP maintained by the Nakhon Phanom Provincial Center for Special Education. This registry represented all children with CP registered at the Center at the time of data collection and served as the initial sampling frame. Eligible participants were mothers who were the primary caregivers of a child with cerebral palsy, had provided care for at least 1 year, and were able to communicate in Thai. This criterion was applied to ensure sufficient caregiving experience, particularly within extended family contexts where caregiving roles may be shared across generations. Exclusion criteria, consistent with the original study protocol, included mothers with a diagnosed mental health condition or those currently receiving treatment for psychological disorders.
A total of 34 mothers met the inclusion criteria, and none met the exclusion criteria. All eligible participants were approached for participation, and none declined. Although 34 mothers met the inclusion criteria and agreed to participate, data collection ceased at 25 interviews as thematic saturation had been reached. Purposive sampling was used to capture variation in caregiving experiences, including differences in caregiving duration, family structure, and child functional status. See Figure 1.

Participant recruitment and sampling process.
Access to participants was facilitated through collaboration with the special education center and community gatekeepers. These gatekeepers, including local educators and community members familiar with the families, assisted in identifying eligible participants, coordinating initial contact, and supporting the arrangement of home visits. This collaborative approach enhanced cultural sensitivity, facilitated trust-building within the community, and supported accurate verification of children’s diagnoses, while ensuring that participation decisions remained voluntary and free from coercion.
Data collection proceeded until thematic saturation was reached, defined as the point at which no new themes or meanings emerged from the data. Saturation was determined collaboratively by the research team through ongoing, concurrent data analysis. Saturation was achieved after the 22nd interview, at which point no new codes or conceptual insights were identified, and three additional interviews were conducted to confirm the stability and redundancy of the thematic structure, resulting in a final sample of 25 participants. Participants received a modest compensation of 100 Thai Baht to acknowledge their time.
Data Collection
Data collection was conducted between December 2024 and July 2025 using semi-structured, in-depth interviews in the Northeastern Thai (Isan) dialect. Interviews were conducted by the primary researcher, a female PhD-prepared nurse educator with training in qualitative methodology and experience working with families of children with disabilities, supporting culturally sensitive communication and rapport. Reflexive awareness was maintained throughout to minimize potential influence of the researcher’s background on participants’ responses.
The interview guide was developed based on relevant literature and refined through expert review by three qualitative research specialists to ensure cultural and conceptual validity. It was designed to elicit detailed narratives of mothers’ grief experiences using open-ended and reflective prompts. Table 1 lists the outline of interview questions. Although the guide included predefined topics, it was applied flexibly, allowing participants to shape the direction and depth of discussion. Probing questions were adapted during interviews to minimize leading responses and to ensure that participants’ meanings emerged naturally from their narratives.
Outline of Interview Questions.
Interviews explored caregiving experiences, including perceived impacts on daily life, emotional responses, spiritual beliefs, and significant or challenging moments. Each interview lasted approximately 45–60 min and was audio-recorded with participants’ consent. Audio recordings were transcribed verbatim shortly after each interview, and field notes were documented to capture contextual details and nonverbal cues.
Most interviews were conducted in participants’ homes. In some instances, family members such as children, spouses, or grandparents were present. The researcher ensured that participants were able to speak freely and minimized interruptions where possible. Occasional distractions or brief interjections occurred but did not substantially affect the depth or continuity of the interviews. Follow-up interviews were conducted with selected participants when clarification or elaboration of emerging themes was required. These follow-ups were carried out either in person or by telephone and focused on deepening interpretation and ensuring accuracy of participants’ meanings.
Translation Procedures
All interviews were transcribed verbatim in Thai and initially analyzed in the original language to preserve cultural meanings and contextual nuances. Transcripts and selected quotations were subsequently translated into English by two bilingual translators with expertise in qualitative health research. Back-translation was performed for key excerpts to ensure semantic equivalence between Thai and English versions (Brislin, 1970). Any discrepancies were discussed among the translators and research team until consensus was reached. Particular attention was given to culturally embedded concepts to maintain the integrity of meaning during translation.
Data Analysis
Data were analyzed using inductive thematic analysis (Braun & Clarke, 2006). Transcripts were read repeatedly to achieve immersion, followed by open coding to identify meaning units related to experiences of grief. Codes were iteratively grouped into categories and developed into themes reflecting shared patterns across participants. Initial coding was conducted independently by two researchers. Subsequently, all three researchers were actively involved in reviewing codes, refining categories, and developing themes through iterative discussions and consensus. Differences in interpretation were resolved collaboratively with reference to the original transcripts. Analysis was conducted primarily in Thai to preserve cultural meanings, with selected excerpts translated into English. An audit trail was maintained, including coding frameworks, analytic memos, and records of team discussions. Trustworthiness was enhanced through member checking, peer debriefing, reflexive discussions, and examination of divergent cases (Lincoln & Guba, 1985; Nowell et al., 2017).
Results
Participant Characteristics
A total of 25 mothers participated in this study. Participants varied in age, caregiving duration, and family structure, reflecting diverse caregiving contexts in Northeast Thailand. All participants were primary caregivers of children with CP for at least 1 year. Children with CP ranged in age from 3 to 15 years. Family arrangements included both nuclear and extended systems. In several cases, caregiving occurred within extended family contexts where grandparents provided supportive roles; however, all participants were mothers who assumed primary caregiving responsibility. This variation provided a broad range of perspectives on caregiving experiences and the meaning of grief within the local cultural setting. Participant characteristics are summarized in Table 2.
Participant Characteristics (N = 25).
Note. EF = Extended Family; NF = Nuclear Family. Cultural Context Note: Xiow (a sworn friendship bond in the local dialect) refers to a culturally recognized form of lifelong friendship characterized by mutual support and enduring relational commitment. Kong Sibsi (the 14 moral rules in the local dialect) refers to a traditional moral framework guiding appropriate conduct within families and communities, emphasizing values such as respect, reciprocity, compassion, and social responsibility. Karma, a core Buddhist concept, refers to the understanding that present circumstances are shaped by past actions, providing a moral and existential framework through which individuals interpret and accept life experiences.
The analysis generated three interrelated themes that elucidate how grief was constituted and negotiated within the context of caregiving for children with CP: (1) confronting a disrupted life trajectory, (2) embodying continuous caregiving as lived loss, and (3) negotiating meaning through relational and cultural resources. Collectively, these themes demonstrate that grief extended beyond an episodic emotional response and was enacted as an ongoing, culturally mediated process shaped by caregiving practices, relational dynamics, and moral frameworks embedded within the Northeastern Thai context.
Theme 1: Confronting a Disrupted Life Trajectory
The diagnosis of CP was experienced as a critical rupture that destabilized mothers’ anticipated life trajectories and reconfigured expectations of motherhood. In this context, grief emerged as the loss of an imagined future rather than solely an immediate emotional reaction. Participants described an abrupt sense of cognitive and emotional arrest at the point of diagnosis:
When I first heard, my mind froze. I couldn’t think of anything . . . it felt like my whole world stopped. (P03) Everything I had hoped for my child disappeared in that moment. (P11)
These accounts illustrate how grief was anchored in the collapse of future-oriented expectations and maternal identity. The diagnosis marked a decisive turning point, initiating an ongoing process of uncertainty and reinterpretation of the maternal role. Variation in initial responses was evident. Mothers with prior exposure to disability within their family or community described a more moderated and gradual adjustment. This pattern suggests that familiarity with disability shaped both the intensity and trajectory of initial grief, attenuating the immediacy of emotional disruption and enabling a more incremental process of meaning-making.
Theme 2: Embodying Continuous Caregiving as Lived Loss
Grief extended beyond the point of diagnosis and became embedded within the ongoing, embodied realities of caregiving. Participants described caregiving as physically demanding, temporally unbounded, and emotionally sustained, such that grief was enacted through everyday practices rather than experienced as discrete episodes. Participants emphasized the cumulative physical demands of caregiving tasks, particularly those involving lifting, carrying, and sustained bodily effort over time:
I wake up, my arms ache, I feel weak . . . but I still have to keep going every day. (P07)
The absence of temporal boundaries further intensified this experience, as caregiving responsibilities were continuous and without respite:
There is no break. Even when I’m tired, I cannot stop being a mother. (P15)
Taken together, these accounts demonstrate how grief was embodied through the physical and temporal conditions of caregiving. The strain described by participants reflects not only fatigue but also a deeper form of lived loss, encompassing diminished autonomy, restricted life opportunities, and the enduring weight of responsibility, alongside underlying moral and emotional tensions associated with sustaining caregiving roles. In this sense, caregiving constituted both the context and the mechanism through which grief was continuously experienced.
However, this embodiment of grief was not uniform. Some mothers described a gradual normalization of caregiving demands, integrating these routines into daily life with limited emotional expression. Others framed caregiving primarily as a moral obligation, emphasizing endurance and responsibility over the articulation of distress.
These variations indicate that while caregiving demands were consistently present, the meanings attributed to these experiences differed. Grief, therefore, was not only embodied but also interpreted through individual meaning-making processes and culturally embedded expectations of maternal responsibility.
Theme 3: Negotiating Meaning Through Relational and Cultural Resources
Mothers actively negotiated the meaning of their caregiving experiences through engagement with interpersonal relationships and culturally grounded belief systems. These resources functioned not as isolated supports but as interconnected frameworks through which grief was interpreted, managed, and, in some cases, transformed.
Support from family members, particularly husbands and grandparents, was experienced as meaningful when it reduced isolation and enabled shared caregiving responsibilities:
My husband helps when he can, and my mother stays with my child when I am tired . . . I don’t feel alone. (P09)
Within extended family contexts, such support reflected culturally normative caregiving arrangements and reinforced a sense of collective responsibility. Beyond kinship networks, participants also described meaningful emotional support grounded in culturally specific relational bonds. The concept of Xiow, or sworn friendship, emerged as a distinctive source of enduring mutual commitment and psychosocial support:
My female Xiow, a lifelong friend, always visits and encourages me, saying we share this life’s path together. That keeps me strong. (P04)
This form of relationship extends beyond conventional friendship, reflecting a culturally recognized bond characterized by emotional closeness, shared life trajectories, and an expectation of unwavering support. Within this relational framework, caregiving was not experienced solely as an individual burden but as part of a broader network of sustained interpersonal connectedness.
Support from the Nakhon Phanom Provincial Center for Special Education and special education instructors was described primarily in instrumental terms. Participants emphasized the value of practical guidance and caregiving knowledge, which enhanced confidence and competence rather than directly alleviating emotional distress:
The teacher showed me how to care for my child better . . . it made me feel more confident. (P18)
At a deeper interpretive level, participants drew upon spiritual beliefs to make sense of their experiences. Beliefs related to karma provided an existential framework through which suffering was understood and contextualized:
I believe this is our karma. I have to take care of my child as part of my duty. (P05)
Through this lens, caregiving was interpreted not as a random misfortune but as part of a broader moral and spiritual order, enabling some mothers to reframe their experiences in ways that supported acceptance and endurance. Complementing this existential understanding, the principles of Kong Sibsi (the fourteen moral rules) guided how participants responded to these circumstances in their daily lives:
The fourteen moral rules guide us to be patient and kind. I follow that every day to stay peaceful. (P15)
These moral teachings emphasized patience, compassion, and social responsibility, shaping caregiving as an ethically grounded practice rather than solely an emotionally driven experience. While karmic beliefs helped explain why suffering occurred, Kong Sibsi informed how participants enacted their roles within that reality. Engagement with Buddhist practices and interactions with monks further reinforced these interpretive processes, contributing to a sense of acceptance and inner stability for some mothers. Despite the availability of these relational and cultural resources, their effects were not uniform. Four mothers described persistent distress and an absence of meaningful solace:
People tell me to accept it, but I still feel lost . . . nothing really helps. (P21)
What distinguished these cases was not merely limited access to support, but the absence of meaningful integration of these frameworks into their personal understanding. These mothers reported difficulty connecting with relational support, limited engagement with spiritual practices, or challenges in reconciling cultural beliefs with their lived realities.
This divergence underscores that relational and cultural resources functioned as contingent rather than universal mechanisms of meaning-making. When these frameworks—including relational solidarity expressed through Xiow, existential interpretations grounded in karma, and moral guidance derived from Kong Sibsi—resonated with participants’ lived experiences, grief could be reinterpreted and integrated. When such alignment did not occur, grief remained unresolved and resistant to transformation.
These findings suggest that grief is shaped by the interplay of relational, spiritual, and moral frameworks within the local cultural context, highlighting the culturally situated nature of caregiving.
Discussion
This study extends understanding of maternal grief in the context of caring for children with CP by showing that grief is not a linear or time-limited process, but an ongoing, culturally mediated experience shaped through relational and moral dimensions grounded in Buddhist beliefs (Boss, 2006; Kleinman, 1988; Park, 2022; Stroebe et al., 2017). In contrast to stage-based models that assume progression toward resolution, the findings indicate a fluid and recursive pattern in which grief is interwoven with everyday caregiving (Klass et al., 2014; Neimeyer, 2019). Mothers’ accounts did not reflect movement from distress to recovery; rather, grief was reactivated and reshaped through changing caregiving demands, relational contexts, and evolving interpretations (Neimeyer, 2019; Park, 2022; Stroebe & Schut, 2010). Grief thus emerges not only as an emotional response but as a continuously negotiated lived experience.
Grief was embedded within moral and spiritual systems that shaped both meaning and expression. References to karma reflected a culturally grounded understanding that present circumstances are shaped by past actions, providing an interpretive lens through which caregiving was rendered meaningful rather than arbitrary (Keown, 2013; Kleinman, 1988; Mattingly, 2010; Park, 2022). Caregiving was frequently described as obligation and responsibility, aligning with Buddhist ethical concepts such as karuṇā (compassion) and moral duty within family relationships (Jooprempree & Jong-udomkarn, 2019). These perspectives help explain why caregiving was sustained despite strain and why distress was not always explicitly expressed. Rather than positioning caregiving solely as burden, participants’ accounts suggest that grief was intertwined with moral suffering, reflecting tensions between lived hardship and ethical commitment.
These findings extend perspectives such as ambiguous loss by showing that uncertainty and enduring caregiving demands are interpreted through culturally specific moral and spiritual systems (Boss, 2006; Kleinman, 1988; Park, 2022). While ambiguous loss emphasizes unresolved and persistent uncertainty (Boss, 2006), the present study indicates that such experiences are also morally and spiritually situated. The integration of karmic beliefs and frameworks such as Kong Sibsi suggests that participants did not merely endure ambiguity but interpreted it through culturally meaningful structures that supported acceptance and social responsibility (Aulino, 2019; Bancha et al., 2023; Punaglom et al., 2022).
Relational processes were central to how grief was negotiated. In addition to family support, the findings highlight the role of Xiow, a culturally institutionalized form of sworn friendship in Northeastern Thai communities. Often formalized through rituals such as symbolic wrist-tying, this bond reflects lifelong commitment and mutual care within enduring social obligation. In everyday life, Xiow is enacted through ongoing contact, practical assistance, and emotional presence, particularly during hardship (Ratsamee, 2025; Thiengtham et al., 2024). Within caregiving, these relationships functioned as sustained psychosocial support extending beyond kinship structures, underscoring the importance of locally embedded relational systems not fully captured in conventional models of social support (Tsai & Papachristos, 2015).
Not all participants experienced these resources as equally supportive. Accounts of four mothers who reported persistent distress indicate that the presence of cultural systems does not ensure meaningful integration or relief. These participants described difficulty connecting with support or reconciling their experiences with prevailing beliefs. This variation suggests that cultural and spiritual systems function as interpretive resources rather than deterministic solutions, with their influence shaped by individual engagement.
An important distinction emerging from the findings is between caregiver burden and grief. While caregiver burden refers to physical strain, role overload, and caregiving-related stress, grief encompasses broader existential and meaning-oriented dimensions, including loss of anticipated futures, identity shifts, and ongoing interpretation (Liew et al., 2018; Manevich et al., 2023). Although these constructs may overlap, maintaining this distinction is essential for understanding participants’ experiences and informing appropriate support (Yehene et al., 2021).
These findings have implications for transcultural nursing practice. Assessment should extend beyond standardized measures of burden to include culturally informed understandings of grief, moral obligation, and spiritual meaning. Interventions should be responsive to local systems, including spiritual beliefs, moral values, and relational practices such as Xiow. Engaging family, community resources, and, where appropriate, Buddhist spiritual leaders may enhance cultural relevance. At the same time, practitioners should remain attentive to individual variation, recognizing that not all caregivers derive comfort from available cultural resources.
Taken together, the findings suggest that grief is shaped by the interplay of relational, spiritual, and moral dimensions within the local cultural context, underscoring the need for culturally responsive support for mothers of children with CP. These insights also highlight the potential value of culturally informed assessment approaches. Participants’ accounts suggest that maternal grief may not be fully captured through assessments focused primarily on caregiver burden or psychological distress. Exploring how mothers understand their caregiving experiences, including the influence of family relationships, spiritual beliefs, moral responsibilities, and culturally specific sources of support, may provide a more comprehensive understanding of their needs. Future research could build on these findings to develop and evaluate culturally informed assessment questions and approaches that are sensitive to the relational, moral, and spiritual dimensions of caregiving.
Limitation
Several limitations should be considered. Recruitment through a special education center and community gatekeepers may have limited participation to mothers already connected to support systems, potentially excluding more socially isolated caregivers. Although the interview guide was applied flexibly, prompts may have influenced participants’ accounts. Participants were drawn from relatively similar socioeconomic and cultural contexts within a rural Northeastern Thai setting, and shared conditions may have contributed to convergence in narratives. While divergent cases were included, their limited number restricts exploration of variation. The study was not designed to examine differences in grief experiences according to children’s age or gender. Future research may benefit from exploring whether these characteristics influence how maternal grief is experienced and interpreted within specific cultural contexts. Accordingly, findings may be most transferable to similar rural, Buddhist contexts, and caution is warranted when extending them to other settings.
Conclusion
This study conceptualizes grief among mothers caring for children with cerebral palsy in Northeast Thailand as an ongoing, contextually embedded process intertwined with ongoing caregiving practices. Grief was shaped through relational, moral, and spiritual dimensions, with participants drawing on culturally grounded frameworks, including karmic beliefs, moral orientations such as Kong Sibsi, and relational ties such as Xiow, to interpret and sustain their experiences. These findings extend existing literature beyond caregiver burden by foregrounding the existential and meaning-oriented dimensions of maternal grief, while also highlighting variation in how such cultural resources are experienced. Implications point to the need for culturally responsive approaches that engage local moral and relational systems, as well as spiritual beliefs, in caregiving support and intervention, to better align with caregivers’ lived realities. The findings may also inform support initiatives within the Nakhon Phanom Provincial Center for Special Education. Culturally congruent caregiver support groups, peer-support opportunities, and family-centered programs that acknowledge local moral, relational, and spiritual resources may help strengthen support for mothers caring for children with CP. Such approaches may provide opportunities for mothers to share experiences, reduce isolation, and access support in ways that align with their cultural context. This study contributes to transcultural nursing by emphasizing the importance of situating grief within locally grounded systems of meaning.
