The sample included 177 outpatients diagnosed with BD. Latent class analysis was conducted to replicate the identified groups of a previously conducted study using a smaller but overlapping dataset. Between‐class and pairwise analyses with measures of suicidal desire and acquired capability were conducted.
Results
As expected, the classes characterized by severe depressive symptoms and mixed symptoms …
