Substance abuse and lifestyle among an urban schizophrenic population: some observations

A comparison of treatment adherence in individuals with a first episode of psychosis and inpatients with psychosis

In predicting treatment compliance in individuals with severe mental illness, research has focused on variables such as substance abuse, personality, history of child abuse, and symptomatology, although these relationships have not been investigated in great detail in individuals at the onset of mental illness. To better understand these correlates of treatment compliance, two samples were examined: a sample of 117 individuals presenting with a first episode of psychosis and a more chronic forensic sample of 65 participants recruited from a psychiatric hospital. These samples were investigated for service engagement in terms of violence history, substance abuse, symptom severity, psychopathic traits and history of childhood abuse. Linear regressions performed for the first episode sample revealed that childhood physical abuse was the strongest predictor of poor service engagement, followed by problems with alcohol, a history of physical violence, any history of violence and higher psychopathic traits. Linear regression revealed for the forensic group that a lower level of service engagement was most strongly predicted by a history of childhood abuse and a higher score on the Brief Psychiatric Rating Scale (BPRS). Results are presented in light of the existing literature and clinical implications are discussed.

Comorbid schizophrenia and substance abuse: a review of epidemiology and course

Over the last dozen years, our knowledge regarding comorbid schizophrenia (SCZ) and substance use disorder (SUD) has evolved in several ways. First, the rate of lifetime comorbid SCZ-SUD appears to have increased another 20-30%, so now about 70-80% of persons with SCZ have lifetime SUD. Second, early remission of SUD has become commonplace among patients with SCZ, perhaps outnumbering the number of SCZ-only patients as well as those with active SCZ-SUD. Third, sustained SUD remission is well demonstrated, though the rates may yet be low. Fourth, research on comorbid SCZ-SUD is filling out our knowledge in many areas, including the characteristics of SCZ patients at risk for SUD, reasons SCZ patients seek out substances, effects of various substances on SCZ course and symptoms, and obstacles to SUD recovery in people with SCZ. The influence of SUD treatment and self-help on epidemiology and course has not been adequately evaluated. Primary prevention and early treatment of SUD in SCZ patients are still relatively neglected, though they offer our greatest hope for enhancing the lives of people with SCZ and improving the cost efficacy of care.

Schizophrenic Patients and Cocaine Use: Antecedents to Hospitalization and Course of Treatment

This study was designed to assess whether cocaine abuse was associated with a different set of antecedents and course for hospitalized schizophrenic patients. Forty-three cocaine-using and 27 non-cocaine-using patients with schizophrenia admitted to a dual diagnosis unit were compared with regard to antecedents to hospitalization such as prior treatment episodes, reliance on drugs for pleasure and tension reduction, and criminal history as well as course of hospital treatment. Cocaine-using patients were more likely to have had a history of prior inpatient drug treatment and to rely on drugs to a greater extent for tension reduction and pleasure. There was a trend for cocaine users to have a history of arrests for violent crimes. Although cocaine-using patients exhibited lower levels of global distress during the first week of hospitalization, they were no different from their counterparts who abused nonpsychostimulant drugs with regard to outcome of hospital treatment. These findings suggest that the lifetime course of illness among schizophrenic patients presenting for hospitalization who abuse cocaine may be characterized by episodes of repeated inpatient drug treatment and impaired impulse control. More rigorous discharge planning and aftercare program monitoring in the community as well as stress management interventions directed to tension reduction are therefore warranted.
