To assess the face, predictive, and construct validity of dopamine-mediated prepulse inhibition disruption in rats as an animal model for sensorimotor gating deficits in schizophrenia.
Face validity was examined by comparing prepulse inhibition responses between humans and rats, alongside testing the dopamine agonist apomorphine in rats.
Predictive validity was measured by evaluating the restoration of prepulse inhibition by typical antipsychotics and clozapine against their clinical potency and D2-receptor affinity.
Construct validity was evaluated by infusing dopamine into the rat nucleus accumbens in the presence or absence of haloperidol.
Face validity was confirmed as stimulus manipulations altered prepulse inhibition similarly in humans and rats, and apomorphine reliably induced prepulse inhibition deficits.
Predictive validity was established by strong correlations between prepulse inhibition restoration in apomorphine-treated rats and clinical antipsychotic potency (rs = .991) as well as D2-receptor affinity (rs = .893).
Construct validity was supported because dopamine infusion into the nucleus accumbens disrupted prepulse inhibition, and this impairment was blocked by haloperidol.
