The relation of social support-seeking to quality of life in schizophrenia.

Social support-seeking has been shown to improve the outcome of schizophrenia. However, no study to date has documented the impact of social support seeking on self-perceived quality of life in schizophrenia, particularly not on the relation between symptoms and quality of life. The present study explored this issue with a sample of 58 outpatients diagnosed with schizophrenia without comorbidity. Social support seeking, symptoms (positive, negative, and extrapyramidal), and multidimensional self-reported quality of life were assessed cross-sectionally. Negative symptoms were inversely related to the quality of life domain of activities of daily living. Other symptoms and social support-seeking were not related to quality of life, and social support-seeking did not interact with symptoms in their relation to quality of life. Social support-seeking may thus not be beneficial (nor disruptive) as a way of coping with symptoms in schizophrenia. More studies are needed in order to investigate the relation of social support-seeking to symptoms and to quality of life in serious mental illnesses such as schizophrenia, so that interventions with persons suffering from these disorders may be better guided.

Comparison of sexual activity of women and men after a first acute myocardial infarction.

Studies of gender differences in the sexual activity of men and women after a first acute myocardial infarction (AMI) have produced conflicting results. The present study was performed to determine whether there are gender differences (1) in the quantity and quality of sexual activity after a first AMI, and (2) in the relations between selected demographic and medical variables and sexual activity after AMI. Four hundred sixty-two men and 51 women with a first AMI were interviewed once before discharge and again 3 to 6 months after AMI. Patients' demographic and medical background and their frequency of and satisfaction with sexual behavior were obtained from the interviews and from medical charts. Analyses of variance showed that women reported significantly less frequency of and satisfaction with sexual activity than men before and after AMI. Both women and men reported significantly less sexual activity and less satisfaction with sexual activity after AMI than before AMI. The decrease in frequency of and satisfaction with sexual activity after AMI was similar for women and men. The relations between selected demographic and medical variables such as age, education, and perceived health before the first AMI and the frequency of and satisfaction with sexual activity of the women and men did not appear to be affected differently by the AMI. A first AMI appears to reduce the frequency of and satisfaction with sexual activity of women and men similarly 3 to 6 months after AMI.

Psychosocial adjustment in patients after a first acute myocardial infarction: the contribution of salutogenic and pathogenic variables. Israel Study Group on First Acute Myocardial Infarction.

OBJECTIVE: To ascertain the differential and independent impact of sociodemographic, medical, and psychologic variables assessed at patients' hospital discharge on these patients' psychosocial adjustment in several domains of life 3 to 6 months later. DESIGN: Two-hundred ninety Israeli male patients, aged 30 to 65 years, with a documented first acute myocardial infarction (AMI) were interviewed once before discharge and again 3 to 6 months postinfarct. Sociodemographic, medical, and psychologic data were elicited at the first interview and completed from medical information in the hospital files. Psychosocial adjustment in seven significant life domains was evaluated by the Psychosocial Adjustment to Illness Scale-Self-Report Version (PAIS-SR) at the second interview. Hierarchical regression analysis was used to examine the relation between the sociodemographic, medical, and psychologic variables at discharge to psychosocial adjustment in the different life domains 3 to 6 months later. RESULTS: Psychologic variables, such as depression, sense of coherence, and social support, and the sociodemographic variable of educational level at discharge predicted a relatively substantial amount of variance in psychosocial adjustment in most PAIS-SR-measured life domains. Low to moderate relations were found between such medical variables as Killip class, heart disease before AMI, other medical conditions, and perceived health before first AMI and psychosocial adjustment in specific life domains. The results also raised the possibility that part of the impact of the medical variables at discharge on psychosocial adjustment 3 to 6 months later may have been mediated by the psychologic variables. The centrality of the psychologic and domestic life domains to psychosocial adjustment in post-AMI patients was also suggested by the results. CONCLUSIONS: Both external and internal pathogenic (depression) and health proneness variables (sense of coherence and social support) at discharge predict psychosocial adjustment in most life domains 3 to 6 months after AMI.

LD, interpersonal understanding, and social behavior in the classroom.

This study used Baron and Kenny's (1986) criteria for mediation to investigate the extent to which interpersonal understanding mediates the relation between learning disabilities (LD) and social adaptation in the classroom. Twenty-two children with and 22 children without a diagnosis of LD completed a semistructured developmental clinical interview measure of interpersonal understanding. They were also rated by their fourth- and fifth-grade teachers on a measure of social adaptation in the classroom. Interpersonal understanding and social adaptation in the classroom were found to be positively correlated. Children with LD exhibited less interpersonal understanding and social adaptation. Although this group difference on social adaptation was greatly reduced when interpersonal understanding was statistically controlled, it remained statistically significant. These results suggest that reduced social adaptation in the classroom and lower interpersonal understanding are both associated with a diagnosis of LD. However, they do not conclusively support the claim that interpersonal understanding mediates the relation between LD and social adaptation. Thus, whether the social difficulties of people with LD stem from the same complex phenomena that produce these people's learning problems remains an open question.

Cerebral hemispheric asymmetries in processing lexical metaphors.

This study investigated semantic priming for literal (stinging-mosquito) and metaphoric (stinging-insult) associates presented to either the left or right visual fields (RVF/LVF) across stimulus-onset-asynchronies (SOA) of 200 and 800 ms. For the short SOA condition, facilitation was found for metaphorically related targets in both visual fields (VFs) while literally related targets were facilitated only in the RVF. For the long SOA condition, metaphorically related targets were facilitated in the LVF whereas literally related targets were facilitated in the RVF. These results support previous findings indicating an enhanced role of the RH in metaphoric comprehension. In addition, the present results are in accordance with current models of hemispheric semantic processing.

Levels of sentence constraint and lexical decision in the two hemispheres.

This study used a lexical decision-priming paradigm to investigate the relative sensitivity of the two cerebral hemispheres to linguistic constraint. Level of constraint of syntactically and semantically correct priming sentences was determined by the Cloze procedure and constraint was manipulated by means of these sentences. High-, medium-, and low-constraining as well as neutral incomplete sentences were presented centrally prior to the appearance of a target word or nonword either to the left or to the right visual field of sixteen righthanded subjects. The hypothesis tested was that the left hemisphere benefits more from linguistic constraint than the right hemisphere. Although reaction time data generally supported this hypothesis, the right hemisphere also seemed to benefit from the constraint produced by high-constraint sentences. The relevance of these findings to the manner in which the two hemispheres process different kinds of linguistic material is discussed.

Sexual activity after first acute myocardial infarction in middle-aged men: demographic, psychological and medical predictors.

The study examined important diverse sociodemographic, medical and psychological variables as potential predictors of sexual activity frequency/satisfaction in male patients following a first acute myocardial infarction (AMI). The sample comprised 276 Israeli male patients, age range 30-65 years, with a documented first AMI who were admitted to any of eight medical centers in Israel. All patients were sexually active prior to AMI. Data were elicited from interviews and medical charts on two occasions: before discharge and 3-6 months after AMI. The research variables explained a greater extent of the variance in sexual activity frequency than in satisfaction 3-6 months after AMI (32 and 23%, respectively). Sexual activity frequency/satisfaction prior to AMI were the major contributors to frequency/satisfaction after AMI. Of the other variables, age and education were the major contributors to sexual activity frequency; of these two variables, age was the sole contributor to sexual satisfaction. Medical and psychological variables (diabetes and depression) were minor contributors.

Linguistic processes in the two cerebral hemispheres: implications for modularity vs interactionism.

Three experiments are reported on lexical decision to target stimuli presented to the right or left visual field (RVF, LVF) following a variety of priming stimuli, words, incomplete sentences, and scrambled sentences. Lexical decision performance is always superior for stimuli presented to the RVF. Primes always facilitate the discrimination of words from nonword target stimuli presented to either visual field. However, when the prime is a sentence which is completed syntactically and semantically by a target word (normal, congruent sentence), the facilitation for RVF presented targets is significantly greater than for LVF targets. When the prime is either: (1) a single word, (2) a nonstructured (scrambled) sentence, or (3) a noncongruent-related sentence, the difference in facilitation between RVF and LVF presented targets is much smaller. These data are discussed with respect to (1) the nature of priming by sentences versus words, (2) language processing by the two hemispheres, and (3) modularity versus interactionism in language processing.

Self-concept, marital vulnerability and brain damage.

The present study investigated the influence of a man's brain injury on both his and his wife's self-concept and perception of marital vulnerability. Thirty-six couples in which the husbands had brain damage and twenty-nine couples without disability filled out the Tennessee Self-concept Scale [1], and the Marital Vulnerability Scale [2]. Marital vulnerability of husbands with brain damage was found not to differ from that of the husbands in the control group. However, the marital vulnerability of the wives of the former husbands was lower than that of the other wives. Both men with brain damage and their wives exhibited a decrease in self-esteem and an increase in conflict and pathology. Brain damage appears to affect both the extent and direction of the relations between aspects of the self-concept and marital vulnerability differentially for husbands with brain damage and their wives. Practical and theoretical implications of the negative impact of brain damage upon the person with the damage, upon his wife, and upon their marital relationship are discussed.

Hemispheric specialization or reading habits: evidence from lexical decision research with Hebrew words and sentences.

This paper reports the results of a lexical decision-visual hemifield protocol using Hebrew words and nonwords. The lexical decision task was combined with sentence priming to examine the impact of hemispheric specialization and sentence length. The data are relevant to the Kirsner and Schwartz (1986) hypothesis that reading habits can explain the oft-reported right visual field (RVF) superiority in linguistic tasks. Both the target stimuli and the sentence primes were in Hebrew and 26 male right-handed native Hebrew speakers served as subjects. Hebrew is written and read from right to left. Therefore, according to the favorable foveal viewing explanation (Kirsner & Schwartz, 1986), there should have been no RVF superiority. The results indicated, however, highly significant RVF superiority. Furthermore, priming sentences, written in Hebrew, should direct the attention of the subject to the left visual field in expectation of the appearance of a target word. Nevertheless, the RVF superiority was even more significant when target stimuli were preceded by priming sentences. Both results indicated that reading habits and directed reading attention cannot explain RVF superiority in lexical decision.

Hemisphericity and top-down processing of language.

This study investigated the impact of contextual prompts (priming words and sentences) on the classical finding of superior performance with right visual field stimulation in a lexical decision task. Subjects were presented with prompts of varying lengths (one, three, or six words). The prompts were followed by a target stimulus (word/nonword) to the right or the left visual field. Subjects were required to respond whether the target was a word or a nonword. The major purpose of the study was to determine the extent of right visual field (RVF) superiority, reflecting left hemisphere superiority, in language processing when target stimuli are preceded by semantically meaningful prompts. The results showed that increasing the number of priming words congruent with the target (creating a meaningful context) increased the advantage of the RVF over the left visual field presentation in lexical decision. Thus, even with an available strategy provided by congruent priming stimuli, RVF superiority in lexical decision is retained and even increased.

Plastic surgery on children with Down syndrome: parents' perceptions of physical, personal, and social functioning.

Plastic facial surgery is being carried out on children with Down syndrome with the objective of improving these children's physical, personal, and social functioning. This study investigated the effect of such surgery on parents' perceptions, both of the current status of their children's functioning and of changes in this functioning. Perceptions of parents of children who had undergone this surgery in Israel in the years 1982 and 1983 were compared with perceptions of parents of children who had not undergone the operation. This comparison produced little evidence for the positive impact of the surgery on parents' perceptions of their children's physical, personal, and social functioning.

The influence of gender, handedness, and performance level on specialized cognitive functioning.

Individual differences in performance on neuropsychological tests were analyzed across age (prepubertal to adult), gender, and handedness groups and examined for performance level as a moderating variable. No differences were observed for the factor structure of these tests across ages and between genders, suggesting similar cognitive structures among these groups. Significant differences in performance were observed between males and females and, to a lesser extent, between right and left handers. Of interest, were significant Gender x Handedness and Gender x Handedness x Level (of performance) interactions seen especially in the older (postpubertal and adult) subjects. High performing, right handed males and left handed females performed better on visuospatial tasks while left handed males and right handed females performed better on verbosequential tasks.

Facial plastic surgery for persons with Down syndrome: research findings and their professional and social implications.

The literature on the effectiveness of facial surgery for persons with Down syndrome was reviewed. Research based on impressions of involved persons (e.g., parents and doctors) generally provided evidence for the surgery's effectiveness. However, studies that used before-after research designs, control groups, indirect measures, and ratings of less involved persons were less supportive of the operation's positive effects. Certain of these studies indicated that the operation failed to achieve its goals. Furthermore, in evaluations of the operation, investigators generally did not critically examine the assumptions upon which the operation is based and the professional and social implications of facial surgery for persons with Down syndrome.

The physical, psycho-social and vocational effectiveness of a sheltered workshop for brain-damaged war veterans.

This two-year investigation of the rehabilitation effectiveness of a sheltered workshop for severely brain-damaged war veterans who had been deemed non-feasible for the Ministry of Defense's usual rehabilitation services, included: (a) a multi-disciplinary staff, (b) adapted jobs, (c) client involvement in workshop management and maintenance, (d) client earnings and (e) social activities. Brain-damaged war veterans from the Tel Aviv area constituted the experimental group. Persons with similar neurological impairment, cognitive, emotional disabilities and social handicaps constituted the control group. In interviews at the beginning and end of the research period, the rehabilitation workshop members and the families expressed a significantly greater increase in satisfaction with a variety of major life activities than did members of the control group and their families. It would appear that sheltered work can increase the brain-damaged persons' satisfaction with major life activities by ameliorating the personal, social and vocational dysfunction that accompanies and aggravates the consequence of brain damage.
