Type of onset, presence of precipitating events, mental status, and premorbid instrumental functioning, commonly associated with prognosis in schizophrenia, were studied in relation to the acute-chronic distinction and short-term outcome in 641 schizophrenic patients. Contrary to the general position held by some researchers, none of the clinical predictors (type of onset, precipitating crises, and mental status) appeared to distinguish the two types of schizophrenics, or to contribute substantially to the prediction of readmission. Preadmission social functioning of the two patient groups was more similar than generally indicated by previous reserach. As regards prediction of short-term rehospitalization, the study identified poor relationships with parents, friends, and opposite-sexed peers as important factors for acute patients and antisocial behavior and inability to relate to the opposite sex and others in the community as important variables for chronic patients.

Several studies document sex differences in premorbid and intermorbid role functioning, showing less functional deficit among females. The specific nature of sex differences in role functioning is still poorly understood. The purpose of the present study was to investigate sex differences in symptomatology and role functioning in a sample of 92 inpatients hospitalized for an episode of DSM-III-diagnosed schizophrenic disorder. Patients were randomized at hospital admission to either of two treatment conditions: (1) multimodal hospital treatment with the addition of an inpatient family intervention (IFI) or (2) multimodal hospital treatment without IFI. Results indicated (1) sex differences in levels of substance abuse and antisocial behavior (worse for males both at admission and followup)--dimensions of psychopathology unrelated to the core features of schizophrenia; (2) superior family and occupational functioning in females at followup; and (3) superior clinical response of females to IFI. Data on family response to IFI suggest some ameliorative effects of IFI on critical family attitudes toward female patients as well as greater family compliance with IFI treatment among the families of females. Sex differences in intermorbid family and occupational functioning and response to a family-based psychosocial intervention are discussed in light of data on rejecting family attitudes toward the patient and sex differences in symptomatology. The possible influence of sex-differentiated social role demands on response to IFI is also discussed.

A familial link between schizophrenia and antisocial behavior has been established (e.g., Silverton, 1985). This study examined this relationship in a Danish cohort. The subjects were 36 high-risk males (offspring of a schizophrenic parent) and 36 low-risk males (offspring of parents without psychopathology). This high-risk subjects exhibited more antisocial behavior than the low-risk subjects. We tested the hypothesis of a correlation between neurointegrative deficits, as defined by motor impairment, and antisocial behavior, rated at ages 10-13, in subjects at genetic risk for schizophrenia. Path analyses were conducted from motor impairment at 1 year and motor impairment at 10-13 years to antisocial behavior separately for high-risk and low-risk subjects. Adolescent motor impairment was a significant predictor of antisocial behavior for high-risk subjects. Motor impairment at 1 year was also associated with antisocial behavior for these subjects, although the association was partly due to the indirect effects of motor impairment at 1 year on motor impairment at 10-13 years, which, in turn, was associated with changes in antisocial behavior. As predicted, none of the path coefficients nor the effect coefficient was significant for low-risk subjects.

Previous studies support a relationship between schizophrenia and antisocial behavior. In the present study, offspring of schizophrenics showed a greater degree of antisocial behavior than did offspring of parents without psychopathology. The present study clarifies the interplay between risk for schizophrenia and developmental factors in determining antisocial behavior. Those variables which distinguished high-risk criminal behavior from high-risk non-criminal behavior were irritability and shortened attention span in infancy, paternal absence during ages 15 to 17, lower WAIS Verbal IQ, impoverished neighborhood, family discord and negative attitude towards father. In a multiple regression analysis, paternal absence in adolescence, shortness of attention span, and low Verbal IQ each contributed a unique portion of the variance in antisocial behavior. A block of interaction terms (Stressor X Risk) did not contribute a significant portion of the variance in antisocial behavior, suggesting that those factors which predict antisocial behavior in the high-risk group are the same factors which predict antisocial behavior in the low-risk group. In addition, a significant portion of the variance in phenotypic outcome (criminal vs. schizophrenic) was accounted for by passivity in infancy (predictive of schizophrenia) and low Verbal IQ (more common in high-risk criminals). Shortened attention spans in infancy were found to precede both criminal behavior and schizophrenia in this sample. This feature may therefore indicate a genetic vulnerability to schizophrenia.

A 51-item true-false Impulsive Nonconformity Scale was constructed to measure impulsive antisocial behavior of the sort often reported in the premorbid adjustment of some psychotics. Schizophrenics and schizoaffective patients (N = 46) scored higher on the scale than control (N = 76). An experimental group of 120 aberrantly high-scoring (2 SDs above the mean) college students and 176 control subjects were interviewed using modified versions of Weissman and Paykel's Social Adjustment Scale interview and Spitzer and Endicott's Schedule for Affective Disorders and Schizophrenia-Lifetime Version (SADS-L). The experimental subjects reported more antisocial and nonconforming behaviors than control subjects, supporting the construct validity of the scale as a measure of impulsive nonconformity, and reported more psychotic or psychotic-like experiences, more schizotypal experiences, and more depressive and manic or hypomanic symptoms, suggesting that a portion of the experimental subjects may be at elevated risk for psychosis and/or major affective disorder. Subjects who score aberrantly high on both the Impulsive Nonconformity Scale and our earlier Perceptual Aberration-Magical Ideation Scale are more aberrant on several other measures of schizophrenic-like cognitive slippage than are subjects who score high on only one of the two scales.

Primary alcoholics may display symptoms of affective or psychotic disorders, while mentally ill patients may develop persistent alcohol-related problems. The author discusses the importance of distinguishing alcoholic psychosis from schizophrenia and alcohol-induced confusion from organic brain syndrome. He then outlines the diagnosis and treatment of other alcohol-induced conditions such as alcoholic dementia, antisocial behavior, and drug abuse. After stressing that primary alcoholism can mimic almost any psychiatric disorder, and secondary alcohol abuse can exacerbate any psychiatric symptoms, the author asserts that physicians should routinely include substance abuse as part of the differential diagnosis of psychiatric patients.

The history of psychotic symptomatology was reviewed in 220 consecutive male patients admitted to the San Diego Veterans Administration Center. Transient hallucinations and/or delusions were noted for 43% of the sample. A comparison of background variables in patients with and without histories of psychoses revealed that such symptoms are associated with less early life stability, higher levels of adult antisocial behavior, and a significant increase in use of most illegal drugs. The data indicated no association between a history of psychotic symptoms and a personal or familial history of schizophrenia.

Some clinicians tend to misdiagnose schizophrenia when there is accompanying antisocial behavior, thus depriving the patient of appropriate treatment. Four factors appear to contribute to this misdiagnosis, the most important of which is the nature of the interaction between examiner and examinee. The authors present a case illustration and discuss the implications for treatment.

The validity of subtypes based on antisocial personality disorder (APD) or childhood conduct disorder without adult APD (CD only) in patients with schizophrenia (or schizoaffective disorder) and a substance use disorder (abuse or dependence) was examined. APD patients scored lower on personality measures related to socialization and higher on antisocial behavior, psychopathy, and aggression. APD patients also reported higher rates of aggression and legal problems. APD, and to a lesser extent CD only, was associated with more severe psychiatric symptoms, an earlier age of onset of substance abuse, more severe symptoms of substance abuse, and a stronger family history of substance abuse and psychiatric hospitalization. The findings suggest that schizophrenia patients with APD represent a high-risk subgroup vulnerable to more severe substance abuse, psychiatric impairment, aggression, and legal problems.

The aims of our study were (1) to examine the socio-demographic, clinical characteristics, autopsy and toxicological findings in 392 youth suicides in Paris, between 1989 through 1996, and (2) to analyze the psychodynamic determinants leading up to the onset of the suicide. During the eight-year study period 392 suicides involving young people were investigated at the Institute of Forensic Medicine of Paris. Two hundred and sixty victims (66%) were males. The mean age was 22 years in both sexes. Fifteen percent of the victims were below 20 years. Ninety-two percent of the subjects were single. Forty percent of the victims were students, 35% were unemployed. One third of the victims had previously attempted suicide. Thirty-five percent of the subjects used to take psychoactive prescription drugs and some of them had been under the care of a mental health professional at the time of the suicide. In 40% of the cases a suicide note was found near the body. Depression (70% of victims), schizophrenia, (10%), affective disorders, parent-child relational problems, partner relational problems, adolescent antisocial behavior, and borderline personality were found to be the most frequent diseases and stressors involved in the suicides. The suicide was rarely an accidental reaction to stress. It was constantly preceded by situational distress, which led to suicidal ideas if the adolescent failed to cope with problems. Ten percent were known as heroin users. In more than 40% of the cases, the victim's parents were divorced or separated. The most frequent method of suicide was poisoning followed by jumping from a height, gunshot, subway death, and hanging/asphyxia. Among firearms, a handgun was more likely to be used than rifles (85/15%). Tranquilizers were the most frequent psychoactive drugs used for suicide followed by antipsychotic drugs, antidepressants, and barbiturates (10%).
