Yes, diversity status helps in a lot of ways. I'm not sure that it should. Please hear me out. I understand and fully believe that therapist characteristics can impart some advantage in establishing rapport, etc with clients. I also believe that the social inequality is highly problematic. However,I want to play the devils advocate here because I fully believe that there are some very valid criticisms of diversity efforts (e.g., when does a thing become classifiable as distinctive in its grouping; what makes a subgroup notably distinct) which might impact it as a selection criteria.
1. If the assumption is that matching beliefs/physical characteristics is vital to the establishment of rapport and provision of our services to those groups that are under-served, to what length are we/should we go to ensure that providers are representative of diverse beliefs, backgrounds , etc? A favorite thought experiment of mine about this is 'If we are trying to provide mental health care, should we encourage individuals from extremist, or sometimes even hateful, viewpoints given their ability to reach out to that demographic that might go un-approached otherwise'. Alternatively, how explicitly should we look for this matching even within normal settings? Should I treat only men? Only men from first generation college families? etc.
2. If the assumption is that diversity is vital due to its capacity to increase rapport, does this suggest an insurmountable barrier to those not of a given diversity characteristic/population? And, assuming so, is this barrier (e.g., diversity status related rapport) the best predictor of therapeutic change (not to be confused with overall rapport, which we know accounts for most of it). Sure these factors (overall rapport and diversity rapport) are likely oblique in nature, but it would seem a bit simplistic to suggest their complete linear relationship without moderators. I'm not familiar with any dismantling studies that look at different aspects of rapport sufficiently to answer this. These moderators, to me, seem like the more vital parts of training.
In short, it helps you land positions, but does it make you a better therapist than additional training hours? I'm not sure and that is the goal of training in my eyes. Social barriers/descrimination need to be erased (a valid reason to promote diversity), but I'm not sure that the assumptions underlying some of the justifications justify actions at later points in development. Two doctoral intern applicants (one black and one white) are both already in the field, thus emphasis on diversity at this stage doesn't promote NEW or GREATER diversity. It does early on, such as during initial grad school application, but I don't see how it would when its not as though either would drop out because of their ethnicity/whatever diversity criteria at that point in the game. We emphasize a similar diversification need (e.g., rationales of reduced social barriers and greater opportunity for those who are not as privileged) for first generation college students to get into college and graduate school. We do not emphasize this the same once they have they have their masters in considering further education.
Well, that wasn't as short as I had intended.
Either way, just some thoughts.
