Self-structure in schizophrenia.

This study used a set-theoretical model to construct self-perception structures and person-perception structures for 10 recently hospitalized schizophrenic patients, 10 nonschizophrenic patients recently hospitalized for depression, and 10 nonpsychiatric subjects. Overall self-perception structures were significantly less elaborated in the schizophrenic patients when compared with either the psychiatric or the nonpsychiatric comparison group. No comparable differences were found for measures taken from the person-perception structures. The degree of elaboration of self in the particular context of self as psychiatric patient was found to be correlated (r?=?.74, p     

Perceptions of parental and peer attachments by women with mood disorders.

The relationship between perceptions of parental and peer attachments at various ages and adult mood disorders was examined in 156 women classified as having bipolar disorder or unipolar depression or as nonpsychiatric controls. Nonpsychiatric controls reported a decreased attachment to their parents over time, but they also reported an increased closeness to their mothers in adulthood following a distant adolescence. Never hospitalized, moderately depressed Ss showed a similar trend toward decreased relatedness, but moderately depressed Ss did not report reestablishment of a close relationship with their mothers after adolescence. Severely depressed and bipolar Ss reported little attachment to their mother at all ages. Bipolar Ss also reported little connectedness to their fathers throughout their lifespan and severely depressed women felt less attached than nonpsychiatric controls to peers during development. None of the psychiatric groups reported difficulties with parental overcontrol. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Patients with psychogenic abdominal pain: six years' observation in the medical setting

The author presents data on 24 patients with psychogenic abdominal pain who were followed by nonpsychiatric physicians for up to 6 years. Twenty were women, many of whose symptoms related to loss. Several personality patterns were observed, including histrionic personality, depression, pain-prone personality, and hypochondriasis. No patient sought psychiatric care, although 4 patients eventually required psychiatric hospitalization. Two patients had medical disorders that contributed to the symptoms, and 1 patient died of carcinoma. Pain resolved in only 1 of the patients, but psychosocial functioning improved in half. Those with a shorter duration of pain and no abnormal personality patterns had a better prognosis.     

Display visual angle and attentional scanpaths on the span of apprehension task in schizophrenia.

The effect of display visual angle on span of apprehension (SOA) task performance was investigated in patients with schizophrenia and nonpsychiatric individuals. Narrow and wide visual-angle presentations of 3- and 10-letter arrays were compared. Detection rates were significantly higher with narrow than wide visual angle for nonpsychiatric individuals; the performance of those with schizophrenia was stable across visual-angle conditions. Patients with schizophrenia were best discriminated from nonpsychiatric individuals in the narrow-angle, 10-letter condition. Scanpath analyses, which were based on the pattern of detection rates across different target quadrant locations, suggested that the patients with schizophrenia used a similar number and path of covert scan moves as did the controls. Hypotheses are discussed regarding which of the multiple cognitive processes tapped by the SOA task may be impaired in schizophrenia.

Preference intrasitivity as an indicator of cognitive slippage in schizophrenia.

Describes the development and application of a scale to detect thought disorder by means of preference intransitivity. The scale, containing a total of 120 item pairs to be judged for preference, was administered to 90 Ss (30 schizophrenics, 30 psychiatric controls, and 30 nonpsychiatric controls). Results indicate that schizophrenics produce more intransitive judgments than nonschizophrenics and that the intransitivity score is independent of age and intelligence. Although the scale may not be powerful enough for diagnostic use, the method warrants further development. (18 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Saccadic system functioning among schizophrenia patients and their first-degree biological relatives.

In Study 1, 30 schizophrenia Ss and 27 nonpsychiatric comparison Ss were presented with a fixation task, a visually guided reflexive saccade (prosaccade) task, a predictive tracking task (0.4-Hz square wave), and an antisaccade task. The 2 groups did not differ on either the fixation or prosaccade tasks. Schizophrenia Ss had an increased number of errors on the antisaccade task and had decreased rightward visually guided saccade amplitudes during the predictive tracking task. In Study 2, 13 psychiatric comparison Ss and 32 1st-degree biological relatives of the schizophrenia Ss were compared with the schizophrenia Ss and a larger and older sample of nonpsychiatric Ss (n?=?33) on the predictive tracking and antisaccade tasks. The groups did not differ on predictive saccadic tracking. The schizophrenia Ss and their 1st-degree biological relatives made more errors on the antisaccade task than both the nonpsychiatric and psychiatric comparison groups (who did not significantly differ). Results are consistent with the notion that dysfunction of dorsolateral prefrontal cortex, caudate nucleus, or both is related to liability for schizophrenia.

Reliability and validity of the Addiction Severity Index among outpatients with severe mental illness.

This study provides psychometric data for the Addiction Severity Index (ASI) when administered to persons with severe and persistent mental disorders. Participants were 97 outpatients (26 women) at a public psychiatric facility. The internal consistency of the composite scores was lower in this psychiatric sample than in previous nonpsychiatric samples. Interrater reliability was acceptable for most composite scores but low for many severity ratings. Several scores showed low temporal stability. Validity evidence was weak for the employment and family-social subscales, acceptable for drug and alcohol subscales, and mixed for psychiatric, medical, and legal subscales. Due to mixed reliability and validity evidence, caution should be exercised when using the ASI with patients having severe mental illness.

Validities of short WAIS batteries.

Several short forms of the Wechsler Adult Intelligence Scale based upon several different rationales have been developed in recent years. The present study presents results of a cross-validation of 49 different short forms. Unlike previous studies, the short forms are cross-validated on both a psychiatric and on a nonpsychiatric population. Results revealed that for both the psychiatric and the nonpsychiatric populations (a) the mean estimated and the mean Full Scale scores were significantly different in only 3 of 98 comparisons; (6) correlations between estimated and obtained Full Scale scores were in the high .80's or .90's; (c) in the great majority of instances subjects were placed within one classification of their intelligence classification as revealed by scores on the total test.

Relation of patient attributes to perceptions of the treatment environment.

Assessed the social climate of 4 residential alcoholism programs (a total of 326 patients) using the Community-Oriented Programs Environment Scale (COPES). COPES perceptions were essentially independent of 18 patient background, psychosocial functioning, and alcohol-related characteristics. Considered in conjunction with previous research in other psychiatric and nonpsychiatric settings, the results indicate that perceptions of the social climate of treatment programs are not simply measures of the personal characteristics of the perceivers.

Sexual symbolism and the variables of sex and personality integration.

The purpose was to reassess the hypothesis of sexual symbolism using stimulus figures similar to those presented in Levy's study (see 28: 8696). The hypotheses were: (1) when asked to designate stimulus objects as male or female, Ss respond to elongated, pointed, or penetrating objects as male, and to hollow, rounded, or enclosing objects as female; and (2) psychiatric patients identify these objects as male or female, respectively, less frequently than nonpsychiatric patients. 20 psychiatric patients and 20 college students, each group made up of an equal number of males and females, served as Ss. Both hypotheses were confirmed at significant levels. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Beliefs about mental illness as a functon of psychiatric status and psychiatric hospitalization.

Beliefs about mental illness were assessed among psychiatric inpatients at a VA hospital, the mental health staff responsible for their treatment, and a group of medical and surgical (control) patients. Results indicated that: (a) Psychiatric and nonpsychiatric patients generally hold similar opinions regarding mental illness. Severely disturbed psychiatric patients, however, view mental illness in more moralistic terms than do "normals." (b) Psychiatric hospitalization is generally accompanied by a change in the patient's beliefs concerning mental illness, toward those held by the staff. (c) Psychiatric patients whose beliefs about mental illness are most strikingly influenced by the staff tend to respond most favorably to treatment, as measured by length of hospital stay and gains in self-esteem during the 1st month of treatment.

Movement abnormalities and the progression of prodromal symptomatology in adolescents at risk for psychotic disorders.

The link between movement abnormalities and psychotic disorders is presumed to reflect common neural mechanisms that influence both motor functions and vulnerability to psychosis. The prodromal period leading to psychotic disorders represents both a viable point for intervention and a developmental period that, if studied, could shed light on etiology; however, no published studies have examined the temporal progression of this link. A group with high levels of prodromal symptomatology (i.e., adolescents with schizotypal personality disorder [SPD]; n = 42) and both psychiatric controls (with other personality disorders or conduct disorder [OD]; n = 30) and nonpsychiatric controls ([NC]; n = 49) were recruited. Videotapes of structured psychiatric interviews were coded for movement abnormalities by raters blind to participants' diagnostic status, and follow-up assessments were conducted 1 year later. Controlling for psychotropic medications, the authors found that adolescents with SPD exhibited significantly more motor abnormalities in the face and upper body than did OD and NC controls. At baseline, movement abnormalities were positively correlated with the severity of positive, negative, and total prodromal symptoms. Within the SPD group, baseline movement abnormalities predicted symptom severity 1 year later. Movement abnormalities represent an early risk indicator that may be predictive of later symptom severity and potentially of psychosis onset.

Comparison of the antigen distribution of two US porcine reproductive and respiratory syndrome virus isolates with that of the Lelystad virus

OBJECTIVE: The present study investigates the comorbidity between bulimia nervosa (BN) and the entire range of American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, 3rd rev. ed. (DSM-III-R) personality disorders and controls for the presence of coexisting depression. METHOD: The Personality Disorders Examination (PDE), a structured interview that encompasses all 13 (provisional) DSM-III-R personality disorders, was administered to three groups of subjects: depressed BN patients (n = 15), nondepressed BN patients (n = 15), and nonpsychiatric controls (n = 15). The BN patients were referrals to a dieting disorder unit affiliated with the University of Sydney. They all met DSM-III-R criteria and all had body mass indexes (BMIs) greater than 19. The nonpsychiatric control group were recruited from an undergraduate psychology course. All subjects were given the Bulimic Investigatory Test, Edinburgh (BITE), the Eating Disorders Inventory-2 (EDI-2), the Hamilton Depression Rating Scale (HDRS), and the PDE. RESULTS: 46.7% of depressed BN patients met the criteria for at least one Axis II diagnosis, as assessed by the PDE, and 33.3% of nondepressed BN patients received such a diagnosis, whereas only 6.7% of nonpsychiatric control subjects met this criterion (p < .05). The results of the present study provide support for an increased comorbidity between personality disorders and BN that cannot be attributed to the confounding influence of coexisting depression. DISCUSSION: This finding enables the identification of subgroups of individuals with BN, enabling them to be compared and contrasted. The identification of differences between subgroups may provide information regarding prognosis and differential response to treatment, which could enable more appropriate treatment decisions to be made.     

Subtypes of partner violence perpetrators among male and female psychiatric patients.

The goal of this naturalistic study was to examine heterogeneity among female and male civil psychiatric patients with a history of intimate partner violence (IPV) perpetration. Participants were 567 patients drawn from the MacArthur Violence Risk Assessment Study (J. Monahan et al., 2001). The authors examined subtype composition among 138 women and 93 men with positive histories of IPV and compared these groups with 111 women and 225 men with no histories of IPV. Findings for men and women were consistent with reports from studies of male perpetrators in forensic and community settings in that generally violent/antisocial, borderline/dysphoric, and family only/low-psychopathology subtypes of perpetrators were identified in both men and women. This study provides preliminary evidence for the generalizability of typologies derived from nonpsychiatric partner violence perpetrators to psychiatric populations and suggests that typologies derived from studies of male IPV perpetrators may provide useful guidance for the investigation of female IPV perpetration.

Depression and marital interaction: Concordance between intent and perception of communication.

This study was designed to examine the perceptions and recall of interpersonal communications in marital dyads with a clinically depressed spouse. Nine depressed and 10 nondepressed psychiatric outpatients and 10 nondepressed nonpsychiatric controls interacted with their spouses, both partners simultaneously coding as positive, neutral, or negative both the intended impact of their own communications and the perceived impact of their spouses' messages. Using videotapes of the interactions, observers also coded each message. Analyses suggested that compared with nondepressed subjects, depressed patients have a negative perception of their environment. Although the depressed patients intended and perceived a lower percentage of positive messages and a higher percentage of negative messages, their recall of their coding was accurate. In addition, although they coded and estimated lower concordance than did subjects in the two nondepressed groups, they tended to overestimate their concordance, as did all of the other participants. The observers' coding did not discriminate between groups but was more negative than the participants' self- or the spouse-ratings. Implications of these results both for theories of depression and for approaches to treatment are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Information processing and cognitive organization in unipolar depression: Specificity and comorbidity issues.

This study investigated information processing and cognitive organization in clinical depression. The specificity of various cognitive mechanisms to depression was also examined. Twenty-six depressed/anxious individuals, 24 pure depressives, 25 never-depressed anxious controls, and 25 nonpsychiatric controls completed a modified Stroop task, the Self-Referent Encoding Task, and two tasks designed to assess cognitive structure. Comorbid depressed/anxious, depressed, and anxious groups performed similarly to one another but differed significantly from nonpsychiatric controls, on the processing and organization of negative content. Specificity to depression was also obtained, as both depressed groups endorsed and recalled less positive information and organized positive self-relevant information with less interconnectedness than anxious individuals and nonpsychiatric controls. These results suggest that depressed individuals have an interconnected negative self-representational system and lack a well-organized positive template of self. These findings are discussed in terms of cognitive models of depression and the tripartite model of depression and anxiety. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Communication deviance, attention, and schizotypy in parents of schizophrenic patients

Singer and Wynne's measures of communication deviance were adapted for use with conversational speech and applied to audiotaped speech samples of schizophrenic patients, their parents, and matched nonpsychiatric control subjects. The parents demonstrated levels of language disturbance similar to those of the patients and higher than those of controls. Language deviance in the parents was positively associated with distractibility on a matched-task digit-span measure of attention and with severity scores on a separate schizotypy scale. These findings are discussed with respect to possible cognitive variables underlying the language disturbances and their potential relevance to schizophrenic etiology.     

Secondary structures and starvation-induced frameshifting

The Changes in Sexual Functioning Questionnaire (CSFQ), a structured interview/questionnaire designed to measure illness- and medication-related effects on sexual functioning, is presented with initial evidence of its clinical usefulness in differentiating between those who have sexual dysfunction and those who have no dysfunction. Individuals from clinical and nonclinical samples completed the CSFQ. The sample groups were compared on mean scores on the CSFQ and its subscales. Comparative findings indicate that psychiatric patients diagnosed with a mood disorder have significantly lower sexual functioning when compared with nonpsychiatric outpatients, medical students, and psychiatry residents combined. The CSFQ is a useful measure for assessing medication- or illness-related effects on sexual functioning in a systematic way.     

Erythrocyte ITP pyrophosphohydrolase deficiency in a psychiatric population

A higher incidence of erythrocyte ITP pyrophosphohydrolase deficiency was found among a psychiatric population when compared to a nonpsychiatric group of subjects. Although the incidence was highest among schizophrenics, particularly those diagnosed as paranoid, the majority of the patients did not show such deficiency. The parallelisms between ITP pyrophosphohydrolase and hypoxanthine-guanine phosphoribosyl transferase deficiencies, both characterized by the lack of availability of IMP, and correlated to behavioral disorders, suggest that irregularities of hypoxanthine nucleotides may be implicated in abnormal mental processes.
