I already dread opening this can of worms, but when was the last time you reviewed RCTs of the major classes of psychotropic medications? The effect sizes are not that impressive. So yes, the science to support the value of one discipline or another is not always easy to find.
1. You misunderstand my statement. I wasn't asking for a study that looks globally at all pathology rolled into one.
2. We all have investment in what we're trained in. Many psychiatrists will fight for the death that meds are very very effective. Many of them are unfortunately swayed by the substantial number of pharma sponsored studies.
So have you read through the
bias of your own education? How many of your EST's are definitively shown to be superior to other psychotherapies in head to head comparisons? Some are, don't get me wrong. Check my link for the example with DBT (no follow-up studies, etc.).
I am quite aware of the low effect size of many antidepressants (usually around 0.3).
3. And my statement was not a challenge at all. Fascinating how you read these statements as anything other than a statement.
To quote myself:
there does Not seem to be a consensus in the literature stating that any 1 factor leads to best outcomes for psychotherapy in general, nor for a particular psychopathology.
My point was a lack of consensus on what makes a therapy or therapist superior to another.
But then we turn to more
evidence:
"However, they conclude that the relationship between therapist competence and reduction of depressive symptoms was not as strong or consistent as expected (from one of the studies reviewed).
"...a classification of extensive training was given to studies with more than 137 h of training for therapists,"
"It is perhaps not surprising that extensive training for inexperienced therapists yielded significant effects."
"If close monitoring with feedback on actual clinical performance is crucial during the stage of training in which therapist competence is consolidated ... then practice cases would seem to serve the same function as supervision."
"This dynamic might suggest that adherence is a precursor to competent clinical skill."
"The existing literature suggests that more extensive training
variably leads to increased therapist competence, which is positively related to better patient outcome."
So there's evidence to support all camps.
But as the review authors point out, there is
no consensus on how much training is sufficient to make a competent therapist that actually correlates with better clinical outcome.
