Biopsychosocial-Spiritual Model
Also known as: biopsychosocial-spiritual, BPSS model, holistic treatment model
The biopsychosocial-spiritual model extends George Engel's original biopsychosocial framework by adding a fourth dimension — the spiritual — to the understanding and treatment of addiction. The model holds that substance use disorders cannot be adequately addressed through any single lens: biological predisposition, psychological wounding, social dislocation, and spiritual impoverishment converge to produce the condition, and treatment that neglects any dimension leaves the others unsupported. The spiritual dimension is not a religious preference but the domain of meaning, purpose, and connection to something beyond the isolated ego.
Why Was the Spiritual Dimension Added?
Engel’s 1977 biopsychosocial model was itself a corrective — a challenge to the biomedical reductionism that treated disease as a purely biological event (Engel, 1977). The addition of the spiritual dimension arose from clinical observation that biological, psychological, and social interventions alone fail to account for the existential and transcendent dimensions of addiction and recovery. Marc Galanter and colleagues, writing for the International Society of Addiction Medicine, note that “an emphasis on biological research and pharmacological management has come to predominate over studies on ‘the interconnections of mind, body, and society’ to the detriment of potentially beneficial integrative models” (Galanter, Hansen, & Potenza, 2021). Their position statement affirms that the spiritual dimension is “often culturally resonant with the medically underserved, including racial/ethnic minority groups, individuals of lower socioeconomic status, and women” — populations for whom strictly biomedical models have demonstrably failed (Galanter, Hansen, & Potenza, 2021).
How Does the Model Apply to Addiction Recovery?
William White argues that the field must shift “from a model of acute biopsychosocial stabilization to a model of sustained recovery management” (White, 2007). The spiritual dimension is what makes this shift possible: without a framework for meaning, the individual stabilizes biologically but remains existentially adrift. Jung recognized this in his correspondence with Bill Wilson, identifying the craving for alcohol as “the equivalent, on a low level, of the spiritual thirst of our being for wholeness” (CW 11). The twelve-step program operationalizes the biopsychosocial-spiritual model by addressing biology through abstinence, psychology through inventory and amends, social connection through fellowship, and spiritual development through conscious contact with a power beyond the ego. This four-dimensional integration is the clinical expression of individuation: the process by which the fragmented self reconstitutes around a center the ego does not control.
