In our clinical practice, we have attempted to use a positive psychology approach in working with people with schizophrenia and youths with behavioral disorders. We present three clinical applications that use a positive psychology approach with these populations: group treatment with persons with schizophrenia; individual cognitive stimulation therapy with persons with schizophrenia; and computer-facilitated dialogue and therapy with persons with schizophrenia and adolescents with behavioral disorders. These three clinical applications using positive psychology are consistent with those traditional treatment goals that aim to increase clients' functioning and improve their quality of life. Given that many people with long-standing emotional "problems" have difficulties initiating change or internalizing feedback regarding their behavioral deficits, the therapeutic environment and clinical interactions need to focus equally on clients' strengths and skills.
