Alexithymia is a strange construct. The person who originated the term has expressed misgivings about it.
It literally translates to "without words for feelings", It isn't defined as a disorder per se, but rather a trait that people have to various degrees. There were a lot of bad studies showing alexithymia was correlated to all sorts of mental disorders; however they mostly derive from clinical populations - people who were already messed up. If you researched red-heads in an inpatient hospital, you would find lots of depression and schizophrenia correlated with red-headedness.
Verbal expression is not necessarily meaningful, especially for feelings.
When people attempt this, they often end up simply babbling in circles about the people and events which induced the feelings. This sort of verbal excorcism is the therapists Favorite Thing (at the rate of $100/hr), but doesn't come naturally to everyone, especially males.
And it doesn't necessarily help.
A recent study challenged the notion that talking about feelings helps resolve them; it found just the opposite - the more people talked and talked the worse off they were.
Talking Out Trauma: Not Always a HelpIt seems to me that the construct of alex. is an attempt to pathologize those with differing - and possibly superior - modes of expression. How would you verbalize the exhaltation of beethoven's ninth? The morning sun of Monet's garden?
Should you try?
To me, alexithymia is not a disorder, it is a misguided belief which seeks to pathologize any dissent from it.
Alexithymia is real but that questionnaire is way too ambiguous to be reliable. It assumes everyone thinks about emotions the same way.
I can identify my emotions in terms of a fixed set of words such as "happy", "sad", "nervous", "angry", etc. but I usually feel these words are inadequate. I could describe emotions as most people do in terms of the circumstances that cause them but I’ve found that I often differ from the norm in how my emotions respond to circumstances. The only way I can qualify and be more precise is to describe the accompanying physical sensations. Yet I don't think therapists and average people are as aware of thier own internal sensations as I am and thus they get confused when I try to describe it that way.
