IntroductionGiven that mental illness stigma is a common occurrence amongst people with mental illness and caregivers (CGs) can be a potential victim of stigma themselves, there is a need to examine caregivers’ perspective on the phenomenon. This study is part of a larger study which aims to qualitatively examine the concept of mental illness stigma amongst different stakeholders in Singapore.MethodsFocus group discussions (FGDs) were conducted amongst 21 informal caregivers to explore the experience of stigma encountered by them and their care recipients, and how it may implicate their caregiving experience. Both inductive and deductive thematic analyses were employed to analyze the data.ResultsThree overarching themes of stigma encounters that may have implication on caregiving experience were identified: 1) Stigma within the family; 2) Structural stigma; and 3) Stigma by association. Experience of stigma within family (e.g., social exclusion and lack of understanding) limits the caregiving supports available to CGs. CGs also took up a mediating role between their care recipients and other family who may hold stigmatizing views. Witnessing their care recipients being subjected to structural disadvantages (e.g., employment, school, and mandatory conscription) can induce emotional stresses amongst CGs and motivate them to protest and seek redress on their behalf. Furthermore, encounters of stigma themselves (e.g., being judged or blamed for their loved one’s condition) also led to feelings of guilt and self-blame amongst the CGs.DiscussionThese findings can aid the formulation of interventions in informing CGs on what to expect on their caregiving journey and supporting them in dealing with issues relating to stigma and highlight the importance of anti-stigma efforts in organizational settings such as schools, corporations, and government agencies.
