The occurrence of disability makes people with disabilities more vulnerable to suicide clustering, in which suicidal ideation among household members is influenced by each other. This study analyzed the clustering of suicidal thoughts in households by disability type and its influencing factors by applying the SUR bivariate probit model using pairwise data from the '2018 Disability Life Panel Survey' of people with disabilities and their family members. In the final analysis, 1,798 pairs of externally disabled households, 826 pairs of internally disabled households, and 215 pairs of mentally disabled households were selected. The results showed that the risk of suicidal ideation clustering was greater in the order of mentally disabled households, internally disabled households, and externally disabled households, and the variables differed by disability type: in externally disabled households, the risk of suicidal ideation clustering increased with lower disability acceptance of the person with a disability, more spouses in the family compared to children or other family members, and less frequent professional contact for family members. Among households with an internal disability, the risk of clustering suicidal ideation in the household increased with distance to health care facilities. In households with mental disabilities, the risk of clustering suicidal ideation in the household with a person with a disability increased as the family health of family members decreased. Based on the findings, we recommend individualized practical and policy measures that take into account the type of disability to prevent suicide clustering in households with disabilities.
