Key wordsFamily caregiving, dependent caregiving, dependent older adults, grounded dimensional analysisAbstractPurpose: The aim of this study was to understand how Thai families care for dependent older adults.Design and Methods: The methodology used for the study was grounded dimensional analysis. Participants were 30 adult family members from 15 families who were involved in caregiving. A total of 46 interviews were conducted. Data were collected and analyzed in three phases: (a) calling up dimensions, (b) assigning relative value to each of the dimension considers, and (c) inferring.Findings: In Thai families, "natural caregiving" precedes care of dependent older persons (dependent caregiving). Dependent caregiving begins when dependency is first noticed and care needs are identified. Dependent caregiving is a dynamic process integrating three major processes: (a) mobilizing family members, (b) performing dependent care, and (c) maintaining continuity of care. The consequences of performing dependent care and unpredictable changes lead to care remobilizing.Conclusions: Dependent care for older adults varies across and is influenced by many conditions. Health personnel need to assess and monitor these varying conditions in order to support Thai families caring for dependent older adults.Clinical Relevance: The conceptual model developed from the findings of this study provide a starting place for increasing our understanding of how to help Thai families care effectively and continuously for their older family members.Sunee Lagampan, Mahidol University, Faculty ofPublic Health, 420/1 Rajvithi Rd., Bangkok 10400Thailand is a country where families have historically provided care for their elderly and dependent relatives (Knodel & Chayovan, 2008, 2011; Srithamrongsawat, Bundhamcharoen, Sasat, &* Amnatsatsue, 2007). Nearly 90% of older and disabled elderly in Thailand receive daily care from their families (Knodel & Chayovan, 2008). However, changes in demographics, women's workforce participation, and increasing geographic mobility threaten the family caregiving infrastructure. The drop in average number of children per family from 7 in 1974 to 1.5 in 2000 leaves many fewer available family caregivers (Ministry of Public Health, 2007). These changes will create even greater challenges to continue family caregiving in the future (Knodel & Chayovan, 2011; United Nation Population Fund, 2011).Geographic dispersion has increased significantly, particularly for rural Thai families. Children living outside the province where their parents reside has increased over the past decade from 28% to 35%, with an even greater increase for rural families. This accounts, in part, for the decreasing percentage of older adults living with an adult child (from 77% in 1986 to 59% by 2007; Knodel &* Chayovan, 2011). Despite these changes in family size and structure, the cultural expectation of providing care to parents remains strong (Knodel 8- Chayovan, 2011). The juxtaposition of continuing expecta- tions for family caregiving and changes in family size and structure raises questions about whether and how family caregiving will be sustained.Research on Thai family caregiving has increased over the past 2 decades. Most of the studies are limited to a focus on caregivers who provide hands-on care, assum- ing they are the 'primary" caregivers (Limpanichkul 8 Magilvy, 2004; Sethabouppha 8 Kane, 2005; Subgranon 8- Lund, 2000). Only a few studies have addressed the role of family members who were not providing hands- on care, even though distribution of care among family members is the usual and expected pattern of caregiv- ing in Thai families (Dangdomyouth, 2008; Niyomthai, Tonmukayakul, Wonghongkul, Panpa, 8 Chanprasit, 2010). Research has not yet addressed the dynamics of extended Thai family caregiving. This limits our under- standing of the full range of family caregiving. …
