Interpersonal Needs, Meaning in Life, Suicidal Ideation, and Multidimensional Attitudes Toward Physician-Assisted Suicide Among Korean Older Adults: A Latent Moderated Structural Equation Model

De-identified analysis-ready data, Mplus 7-compatible syntax, variable documentation, and expected key results supporting a latent moderated structural equation model of perceived burdensomeness, thwarted belongingness, meaning in life, suicidal ideation, and seven dimensions of attitudes toward physician-assisted suicide among 483 Korean adults aged 65 years or older. To reduce disclosure risk, original identifiers and demographics are excluded, and suicidal ideation is shared as the three parcels used in the SEM rather than as item-level responses. The package reproduces the baseline latent SEM and the LMS/XWITH interaction model
