Objectives. The Model of Functional Deficits associated with hallucina
tions is used as part of the clinical documentation in the San Jose St
ate University Psychosocial Occupational Therapy Clinic. On the basis
of this model, hallucinations are classified according to functional d
eficits and whether the deficits are a result of the content or intrus
iveness of the hallucinations. This classification is important becaus
e it helps occupational therapists know the full extent of the dysfunc
tion through understanding the underlying pathology. The purpose of th
is classification is to assist in the development of clinical treatmen
t plans that incorporate techniques for coping with hallucinations. Me
thod. The sample included 39 clients seen in the clinic over a 4-year
period. Student occupational therapists were responsible for documenti
ng the classifications using the Model of Functional Deficits associat
ed with hallucinations. The clients' charts were then reviewed retrosp
ectively to classify the hallucinations according to the clients funct
ional deficits. The classification system ranged from Class O, insuffi
cient information, to Class VI, persistent hallucinations with profoun
d functional deficits. With these classifications, interventions were
planned with the clients in order for them to practice coping mechanis
ms (e.g., self-instruction, decreased stimulation, increased stimulati
on) to maintain function during their hallucinations. Results. The fin
dings indicated that 54% of the clients continued to experience halluc
inations (i.e., Class II-Class V), although all received psychotropic
medication, thus necessitating continuing therapeutic intervention. Co
nclusion. This model helps identify specific client experiences that c
an then be used to develop occupational therapy interventions.
