Biopsychosocial eclecticism is incomplete because it does not address
the important issues of differential causation and treatment staging.
Psychiatric serialism goes beyond eclecticism to consider biological,
psychosocial, and existential-moral parameters as equipotential and
hierarchical. What this means in practice is that, after forming a
treatment alliance, the therapist must always assess the evidence for a
biological substrate of disorder and, where feasible, administer the
appropriate biological treatments. On a stable biological platform,
psychosocial interventions can then be utilized to promote the goals of
lieben and arbeiten, and an existential therapy relationship can be forged
to promote personal integrity.
