An evaluation of social and adaptive skills in adults with bipolar disorder and severe/profound intellectual disability.

Lecavalier et al. (2006) compared adults who have both severe intellectual disability and bipolar disorder with adults who have only severe ID.

They used two checklists: the MESSIER rates social skills during real-life tasks, and the VABS tracks daily living skills.

Staff who knew the adults filled out the forms; no new teaching was tried.

The bipolar group used more negative words and tones during social moments.

Both groups scored the same on self-care, money, and other daily living skills.

In short, mood swings hurt social style, not independence level.

Lecavalier et al. (2006) and Lecavalier et al. (2006) look like twins but tell different stories. One paper says bipolar brings negative verbal habits; the other says self-injury plus stereotypy brings negative non-verbal habits. Together they show that different comorbid risks target different social channels.

Barisnikov et al. (2019) extends the line by adding a new 28-item social-adaptive scale. They found that psychopathology level, not Down syndrome versus non-specific ID, drives social gaps. This supports L’s message: treat the mental-health piece first, then teach skills.

Konstantareas et al. (1999) review warns that lithium often fails in rapid-cycling bipolar-ID adults. Pair this with L’s finding of intact daily skills and you get a clear plan: screen social style early, pick mood drugs carefully, and keep teaching life skills because those stay steady.

You now have a fast red flag: if an adult with severe ID starts sounding harsh or negative, check for bipolar signs and review meds. Use the MESSIER for social style and keep the VABS for baseline independence. Treating mood can calm words without needing extra self-care training.
