This study aimed to understand how children of parents with mental illness perceive their situation by analyzing their posts on Swedish Internet forums. The data consisted of 301 comments from 35 threads across 5 forums. Thematic analysis identified four main themes: “Caregiver burden,” “Knowledge seeking,” “Support from the forum,” and “Frustration and powerlessness over health care.” Results indicated that the mental illness of parents significantly impacted the forum writers, leading to feelings of stigma, a need for information and support, and dissatisfaction with the psychiatric care their parents received.
