摘要:
This study aimed to a) assess whether genetic or environmental effects are of similar magnitude in the etiology of GAD in men and women, and b) investigate whether familial (genetic or common environmental) risk factors are the same in men and women, or whether there are gender-specific effects. We obtained a lifetime history of DSM-IIII-R GAD, via face-to-face and telephone interviews, from 3100 complete male-male, female-female, and male-female twin pairs, ascertained through a population-based registry. Biometrical twin modeling was utilized to estimate the relative contributions of genetic and environmental factors to liability for GAD, allowing for gender-specific effects. The familial aggregation of GAD in this sample was only modest. In the best-fitting models, the heritability of GAD was the same in men and women, estimated at about 15% to 20%, with no effects of gender-specific genes detected.

摘要:
Poststroke depression has been associated with impaired recovery of activities of daily living (ADL) during the first 2 years after stroke. This study examined the effect of remission of poststroke depression on recovery in ADL in a double-blind randomized treatment study. Based on a semistructured psychiatric exam and DSM-IV diagnostic criteria, a consecutive series of 23 patients who met criteria for major depression (N= 16) or minor depression (N= 7) were selected and randomly assigned to either active treatment (nortriptyline) or placebo. Functional physical (i.e.,ADL) impairment was assessed using the Johns Hopkins Functioning Inventory (JHFI). Patients whose depressive disorder remitted at follow-up had significantly greater recovery in ADL functions compared with patients whose depression did not remit. There were no differences in demographic variables, lesion characteristics, and neurological symptoms between the two groups, which would explain the significantly greater improvement among the remitted patients. Because both major and minor depression patients who remitted showed greater improvement in ADL than nonremitted patients some of whom were treated with active and some with placebo medication, nonpharmacotherapeutic mechanisms related to recovery from depression appear to mediate this enhanced recovery.

摘要:
Relationships among mild traumatic brain injury (MTBI), posttraumatic stress (PTS), and function were examined in 99 motor vehicle accident (MVA) admissions: 64 in an MTBI group and 35 in a no-MTBI comparison group. Assessments occurred within the first month and at 6 to 9 months. At follow-up, the sample was moderately disabled on the Sickness Impact Profile (SIP), 71% satisfied on the Reintegration of Normal Living Index (RNL), and 42% had returned to work. Only the SIP Psychosocial score was significantly different for MTBI groups; 24% of the sample showed definite symptoms of PTS. This group was significantly more disabled on the SIP, less satisfied on the RNL, and less likely to return to work. The proportion of variance in outcome explained in each model ranged from 32% (Physical SIP) to 44% (RNL). Results suggest the need for clinicians to be more aware of the strong influence of PTS on functional outcomes.

摘要:
This paper reports on the predictive validity of the physical disorders axis (axis III) of the DSM multiaxial diagnostic system at 3-year follow-up. A total of 515 general psychiatric patients were assessed with a semistructured procedure that covers all DSM-III diagnoses and axes, and were subsequently followed up for 3 years. Outcome was assessed with several measures of adaptive functioning. Baseline axis III was analyzed according to a) presence of any physical disorder, b) the number of these, c) presence of major chronic physical disorders (MCPD), and d) the number of these. Prediction of impairment in functioning (Strauss-Carpenter Scale), derived from baseline axis III, ranged from a correlation coefficient of .18 when expressed as the presence of any physical disorder to .35 when represented by the number of MCPD. Furthermore, within patients with specific psychiatric disorders, it was found that number of MCPD reached a predictive validity of .55 for patients with dysthymic disorders, .44 for those with anxiety disorders, and .41 for those with major depression. Comparative multiple regression analyses, controlling for demographic and clinical variables, showed that the number of MCPD at baseline was the most important predictor of functioning outcome among patients with dysthymic disorders and major depression. The number of MCPD experienced by general psychiatric patients seems to be an important predictor of future functioning, particularly for patients with certain psychiatric disorders. This points out the importance of considering the relationship between psychiatric and MCPD when conducting systematic clinical assessments towards the prediction of course and outcome.

摘要:
We studied 655 urban police officers (21% female, 48% white, 24% black, and 28% Hispanic) to assess ethnic and gender differences in duty-related symptoms of posttraumatic stress disorder (PTSD). We obtained self-report measures of: a) PTSD symptoms, b) peritraumatic dissociation, c) exposure to duty-related critical incidents, d) general psychiatric symptoms, e) response bias due to social desirability, and f) demographic variables. We found that self-identified Hispanic-American officers evidenced greater PTSD symptoms than both self-identified European-American and self-identified African-American officers. These effects were small in size but they persisted even after controlling for differences in other relevant variables. Contrary to expectation, we found no gender differences in PTSD symptoms. Our findings are of note because: a) they replicate a previous finding of greater PTSD among Hispanic-American military personnel and b) they fail to replicate the well-established finding of greater PTSD symptoms among civilian women.

摘要:
This study examined gender differences in the relationship of homelessness in schizophrenia to symptom severity, risk behaviors, and prognostic features. Four hundred subjects with schizophrenia were studied: 100 homeless men, 100 homeless women, 100 never homeless men, and 100 never homeless women. Assessments included derivation of five symptom factors by using the Positive and Negative Syndrome Scale (PANSS). Homelessness for the entire sample was associated with greater severity of positive, activation, and autistic preoccupation symptoms, younger age at first hospitalization, and substance abuse (SA). For men only, homelessness was associated with neuroleptic noncompliance (NN). When NN and SA were statistically controlled, symptom severity was not different between the homeless and never homeless. Women, independent of residential status, had more severe negative, activation, and autistic preoccupation symptoms that were not associated with prognostic features or risk behaviors. For both men and women, SA was associated with homelessness, but independent of residence, SA was less severe in women. Additionally, SA was less severe in homeless women than never homeless men. Thus, symptom severity in homeless individuals with schizophrenia appears as an interaction of symptom profiles and risk behaviors that are gender specific. Although cross-sectional analyses cannot distinguish cause from effect, these findings suggest gender-specific routes to homelessness among indigent urban adults with schizophrenia.

摘要:
Persons with schizophrenia are widely recognized to experience potent feelings of hopelessness, helplessness, and a fragile sense of well-being. Although these subjective experiences have been linked to positive symptoms, little is known about their relationship to neurocognition. Accordingly, this study examined the relationship of self-reports of hope, self-efficacy, and well-being to measures of neurocognition, symptoms, and coping among 49 persons with schizophrenia or schizoaffective disorder. Results suggest that poorer executive function, verbal memory, and a greater reliance on escape avoidance as a coping mechanism predicted significantly higher levels of hope and well being with multiple regressions accounting for 34% and 20% of the variance (p< .0001), respectively. Self-efficacy predicted lower levels of positive symptoms and greater preference for escape avoidance as a coping mechanism with a multiple repression accounting for 9% of the variance (p< .05). Results may suggest that higher levels of neurocognitive impairment and an avoidant coping style may shield some with schizophrenia from painful subjective experiences. Theoretical and practical implications for rehabilitation are discussed.

摘要:
Studies on the prevalence of social anxiety in sex offenders show mixed results. This may be due to social anxiety being heightened only in diagnostic subgroups of sex offenders, namely in paraphiliacs. In study 1, 72 mentally disordered sexual delinquents and 30 controls were screened for social anxiety with the Social Interaction Anxiety Scale and the Social Phobia Scale by Mattick and Clarke (German versions). In study 2, 55 mentally disordered sexual delinquents were diagnosed with a structured clinical interview. In both studies, sex offenders were categorized as either paraphilic or impulse control disordered (without paraphilia) according to research criteria. Study 1 showed markedly heightened scores for social anxiety in paraphiliacs, particularly for social interaction anxiety. Study 2 found a high lifetime and point prevalence of social phobia in paraphiliacs for which corroborating evidence was again found in questionnaire results. Implications for further research, diagnostic procedures, and therapy are discussed.

摘要:
Although juvenile obsessive compulsive disorder (OCD) is increasingly recognized as a putative developmental subtype of the disorder, comparisons among children, adolescents, and adults with OCD have been lacking. We aimed to evaluate clinical correlates of OCD in three developmentally distinct groups. Subjects comprised children, adolescents, and adults meeting DSM-III-R and DSM-IV criteria for OCD referred to separate specialized OCD clinics. All subjects were systematically evaluated with structured diagnostic interviews and clinical assessments by OCD experts. Specific clinical correlates and symptom profiles were associated with the disorder in different age groups. These findings support a hypothesis of developmental discontinuity between juvenile and adult OCD and identify age specific correlates of the disorder across the life cycle. Further work is needed to validate whether juvenile-onset OCD represents a true developmental subtype of the disorder.

摘要:
Scientific discussions about false memories have, so far, mainly focused on external determinants (e.g.,therapeutic interventions). However, in some cases, false memories might develop more spontaneously. For example, difficulties in distinguishing between dreams and reality may lead to false memories. The present article discusses two studies (N= 85 and 255, respectively) that examined to what extent such difficulties occur. In both studies, a nontrivial minority of respondents (11.8% and 25.9%, respectively) reported that they had had the experience of not being able to discriminate between dream and reality. As expected, respondents who reported this type of confusion scored higher on fantasy proneness and dissociation measures than respondents who did not report this confusion.
