Do the siblings of schizophrenia patients demonstrate affect perception deficits?

Affect perception deficits have been extensively documented in schizophrenia and are associated with the social dysfunction that is characteristic of this disorder. The two previous studies examined facial affect perception in genetically at-risk samples and yielded mixed results. The current study was designed to provide a rigorous test of affect perception abilities among schizophrenia patients (n=58), their biological siblings without psychosis (n=51), and nonpsychiatric controls (n=49). Participants completed three measures of affect perception, including facial, vocal, and combined modality. Schizophrenia patients performed significantly worse than controls on two of the three affect perception tests as well as a composite index based on all three tests. The performance of the sibling group fell between the patient and control groups on each of the affect perception tests. However, group differences achieved statistical significance only for the composite index with the siblings performing significantly worse than controls and significantly better than the schizophrenia group. These findings demonstrate that subtle deficits in affect perception are detectable in the unaffected siblings of schizophrenia patients when multiple measures of different types of affect perception abilities are used in combination.

The stability of threat perception abnormalities and anxiety disorder symptoms in non-clinical children.

The current study examined the temporal stability of threat perception abnormalities and anxiety disorder symptoms in non-clinical children. One-hundred-and-thirteen primary school children aged 9 to 13 years completed a self-report measure of anxiety disorder symptoms, and were interviewed individually using an ambiguous story paradigm from which a number of threat perception indices were derived. The assessment was repeated some 4 weeks later, so that it became possible to study prospective relationships for threat perception abnormalities and anxiety disorder symptoms. Results indicated that, on both occasions, anxiety disorder symptoms were significantly associated with threat perception abnormalities. Furthermore, threat perception abnormalities were moderately stable with test-retest correlations between 0.44 and 0.63 for the various threat indices and a test-retest correlation of 0.61 for the threat perception composite score. Finally, no evidence was obtained for a direct prospective link between threat perception and anxiety disorder symptoms. Implications for the role of threat perception distortions in the maintenance of anxiety complaints in children are briefly discussed.

Unconscious perception: attention, awareness, and control.

Conscious perception is substantially overestimated when standard measurement techniques are used. That overestimation has contributed to the controversial nature of studies of unconscious perception. A process-dissociation procedure (L. L. Jacoby, 1991) was used for separately estimating the contribution of conscious and unconscious perception to performance of a stem-completion task. Unambiguous evidence for unconscious perception was obtained in 4 experiments. In Experiment 1, decreasing the duration of a briefly presented word diminished the contribution of both conscious and unconscious perception. In Experiments 2-4, dividing attention reduced the contribution of conscious perception while leaving that of unconscious perception unchanged. Discussion focuses on the measurement of awareness and the relation between perception and memory.

II. Do chronic pain patients' perceptions about their preinjury jobs differ as a function of worker compensation and non-worker compensation status?

OBJECTIVES: (1) To demonstrate a relationship between intent to return to preinjury job and preinjury job perceptions about that job; and (2) to demonstrate that worker compensation chronic pain patients (WC CPPs) would be more likely than non-worker compensation chronic pain patients (NWC CPPs) not to intend to return to a preinjury type of job because of preinjury job perceptions. STUDY DESIGN: The relationship between preinjury job perceptions and intent to return to the preinjury job was investigated and compared between worker compensation (WC) and nonworker compensation (NWC) chronic pain patients (CPPs). Within the WC and NWC groups CPPs not intending to return to their preinjury type of work were compared to those CPPs intending to return on preinjury job perception. BACKGROUND DATA: Compensation status, being a WC CPPs or being a non-WC CPPs, has been claimed to be predictive or not predictive of return to work post pain treatment. These studies have, however, ignored the preinjury job stress perception variable as an area of research. METHODS: WC CPPs were age- and sex-matched to NWC CPPs and statistically compared on their responses to rating scale and yes/no questionnaires for intent to return to work and perceived preinjury job stress. In a second analysis, both the WC and NWC groups were divided according to their intent to return to work and statistically compared on their responses to these questionnaires. RESULTS: Both male and female WC CPPs were less likely than their counterparts to intend to return to their preinjury job. Both WC and NWC were found to complain of preinjury job complaints, and these complaints were found to differ between WC and NWC CPPs. An association between intent not to return to work and the perceptions of preinjury job dissatisfaction and job dislike was found for male and female WC CPPs and for male and female NWC CPPs. CONCLUSIONS: There may be a relationship between some preinjury job perceptions and intent to return to the preinjury type of work in some groups of CPPs. However, a specific relationship between WC status, intent not to return to the preinjury type of work, and preinjury job perceptions in comparison to NWC CPPs could not be demonstrated.

Battered women's perceptions of loss and health.

The article reports a study investigating whether a positive relationship exists between a battered women's perceptions of loss and her perceptions of health. The study further investigated whether a period of time away from the abusive situation would change the battered women's perceptions of loss and her perceptions of health. A convenience sample of 20 women who had experienced battering and abuse and had sought help at a protective shelter was studied. Questionnaires on perception of loss, health response, and demographics were used for the collection of data. The findings indicated that a significant relationship exists between a battered women's perceptions of loss and her perception of health. Perceptions of loss and health were shown to decline after a period of 5 days away from the abusive situation. Additional qualitative data obtained from in-depth interviews were also found to be consistent with the quantitative results and supported the literature documented in this study.

What explains nurses' perceptions of staffing adequacy?

BACKGROUND: Much attention is being paid to the adequacy of nurse staffing in acute care hospitals, and much of the information relies on nurses' perceptions about staffing adequacy. Yet, we know little about what influences these perceptions. OBJECTIVES: We examined the impact of hospital characteristics, nursing unit characteristics, nurse characteristics, and patient characteristics on nurses' perceptions of staffing adequacy. We tested three different models, incorporating different conceptualizations that relate current and past characteristics to these perceptions. METHOD: This was a secondary analysis of data from the Outcomes Research in Nursing Administration Project, a longitudinal study conducted in 60 hospitals in the Southeastern United States. RESULTS: Perceptions of staffing adequacy were influenced significantly by the hospital's case mix index and growth in hospital admissions, by the number of beds on a unit, and by patient acuity. Further, current perceptions of staffing adequacy were significantly affected by prior perceptions. CONCLUSION: Based on our results, we present potential interventions for administrators that may ameliorate some of the negative influences on nurses' perceptions of staffing adequacy.

A social network contagion theory of risk perception.

Risk perceptions have, to a great extent, been studied exclusively as individual cognitive mechanisms in which individuals collect, process, and form perceptions as atomized units unconnected to a social system. These individual-level theories do not, however, help explain how perception of risk may vary between communities or within a single community. One alternative approach is based on a network theory of contagion. This approach, emerging largely from organizational and community social network studies, suggests that it is the relational aspects of individuals and the resulting networks and self-organizing systems that influence individual perceptions and build "groups or communities of like-minded" individuals. These social units, it is argued, behave as attitude, knowledge, or behavioral structures. The study reported in this article tests one aspect of this theoretical perspective. The central hypothesis proposes the existence of risk perception networks--relational groupings of individuals who share, and perhaps create, similar risk perceptions. To test this idea, data were collected from individuals involved in a community environmental conflict over a hazardous waste site cleanup. The statistical analysis used a matrix of relational social linkages to compare with a matrix of individual risk perceptions The analysis confirmed the hypothesis suggesting that social linkages in communities may play an important role in focusing risk perceptions.

The social bases of discrepancies in health/illness perceptions.

Health care professionals generally assume that their perceptions and assessments of their patients' health status are accurate and are congruent with those of the patient and other health care providers. However, despite the patient education process, there is evidence that discrepancies in perceptions persist. These discrepancies are of particular concern to nurses because they may interfere with the provision of quality patient care. Poor communication, non-compliance with the treatment regimen, inadequate or unnecessary treatment, and ethical problems could be outcomes of discrepancies in perceptions. In this paper, the literature pertaining to discrepancies in health/illness perceptions is reviewed. As well, several social factors that may affect perceptions are described. These include cultural background, gender, socioeconomic status, experience and role. The effect of occupational role on health/illness perceptions has not been examined systematically. Regarding differences in perceptions of physicians, nurses and patients, further research is required to clarify and explain the nature of discrepancies in health/illness perceptions.

Chronic illness perception in adolescence: implications for the doctor-patient relationship.

OBJECTIVE: To describe the inter-relationship of chronic illness severity as perceived by adolescents with both psychosocial well-being and objective measures of illness severity. Additionally to compared the adolescents' perception of illness severity with how their physicians believe that the adolescents perceive their illness severity. METHODS: The psychological well-being of 48 adolescents with either cystic fibrosis (CF) or insulin-dependent diabetes mellitus (IDDM) was measured by four standardized questionnaires. The adolescents' perception of severity of illness was measured using an original instrument (PSCI), and this measure was compared to their physicians' estimates of how the adolescents perceived the severity of their illness and clinical illness. RESULTS: There were 24 patients in both the CF and IDDM groups. Both groups were found to function well psychosocially; although, there were more patients with low self image compared to normative values. Depression and low self image were associated with a greater adolescent perception of illness severity. For both chronic illness groups, physicians' assessment of assumed adolescent perception of disease severity correlated with clinical indices of disease severity and was higher than the perception of illness severity reported by the adolescents. For adolescents with CF, but not with IDDM, perception of severity of chronic illness correlated with clinical indices. CONCLUSIONS: For adolescents with chronic illness, their perception of illness severity is an important indicator of psychosocial well-being. Physicians do not accurately infer their patients' perception of illness severity.

Complicated and uncomplicated pregnancies: women's perception of risk.

OBJECTIVE: To compare the perception of risk of women with complicated and uncomplicated pregnancies and to determine the relationship between biomedical, psychosocial, and demographic risk factors and women's personal perceptions of pregnancy risk. DESIGN: A descriptive, correlational study. SETTING: Antenatal units and outpatient clinics of two tertiary care teaching hospitals in western Canada. PATIENTS/PARTICIPANTS: A convenience sample of 105 women having a complicated pregnancy requiring hospitalization for more than 48 hours and 103 women with no known complications and no hospitalization during the pregnancy. MAIN OUTCOME MEASURE: Perception of risk during pregnancy. RESULTS: Women with complicated pregnancies perceived their overall risk and risk for specific pregnancy outcomes as significantly higher than women with uncomplicated pregnancies. State anxiety and biomedical risk were positively related to perception of risk, but there was no relationship between stress, self-esteem, or social support and perception of risk. The strongest predictors of self-perception of pregnancy risk were the biomedical risk score and state anxiety. CONCLUSION: Women with complicated pregnancies perceive their risks as higher than women with uncomplicated pregnancies. Both biomedical and psychosocial factors play a role in influencing risk perception. Nursing assessment of the pregnant woman should include discussion with her of her perception of risk.

Exercise and diet interventions improve perceptions of self in middle-aged adults.

The effect of a 1-year exercise and diet intervention program on global self-concept, perceptions of the body, physical competence, exercise mastery, social competence, social comfort, and fitness was examined with 208 healthy individuals (191 males, 17 females) aged 39-49 years (mean age 44.9) with elevated risk factors for cardiovascular disease. The relative utility of the skill development versus the self-enhancement model of the self-concept/behaviour relationship was tested. The participants were randomized into four groups: diet (n = 53), diet and exercise (n = 64), exercise (n = 48) and no active intervention (n = 43). Measurements were made by the Harter adult self perception profile (HASPP) and the self-perception in exercise questionnaire (SPEQ). Two-way ANOVA analyses revealed that exercise participation, with or without diet, enhanced self-perceptions of physical mastery and ability, body perception, fitness and social comfort. The unique contribution of diet indicated enhanced body perception. No effect was found of diet or exercise on global self-concept. Exercise participation had a positive effect on perceptions of the self, and the higher the compliance with the exercise program, the stronger were the effects on the self-perceptions. This supported the skill development model of the self-concept/behaviour relationship. As the pretest self-concept scores did not predict exercise compliance, the self-enhancement model of the self-concept/behaviour relationship was not supported.

Significant others' contribution to early adolescents' perceptions of their competence.

This study measures perceptions of competence in the scholastic and athletic domains and also examines gender differences in these areas. It explores the relative contributions of significant others (namely, parents, teachers, classmates and close friends) for an Australian cohort of early adolescents. A total of 264 children (average age, 11.7 years; 40% female) in Grade 6, their parents and their classroom teachers were surveyed using six modified Harter scales. Analyses supported the notion that the sources related to early adolescents' perceptions were different and that the relative predictive utility of the five sources varied as a function of gender and the domain type. Scholastic competence for males is related to external (father and teacher) perceptions as well as internal (child's) perceptions whereas for females, scholastic competence is related entirely to internal (child's) perceptions. In contrast, athletic competence for males is related only to external (teacher) perceptions, whereas for females athletic competence is related to external (mother) perceptions as well as internal (child's) perceptions. The findings are discussed in terms of their theoretical and practical implications in educational practice.

Relations between perceptions of the teaching environment and approaches to teaching.

BACKGROUND: Previous research has established substantial relations between students' approaches to study in higher education and their perceptions of the learning environment. More recently, there has been a growing body of research into teachers' approaches to teaching and conceptions of teaching. There has, however, been little research into their perceptions of the teaching context. AIMS: This study aimed to develop an inventory of university teachers' perceptions of their teaching environment (PTE) and how those perceptions related to their approaches to teaching. SAMPLES: The interview sample comprised 13 teachers of first year university physics and chemistry courses in two Australian universities, and the survey sample comprised 46 teachers from several Australian universities. METHODS: In the qualitative study teachers were interviewed about the things they thought affected their teaching. The interviews were content analysed, and an inventory was produced. In the quantitative study, the results of the administration of the Approaches to Teaching Inventory and the PTE were analysed by correlational, factor and cluster analyses. RESULTS: This exploratory study found systematic relations between the perceptions and approaches. The relations observed suggest that the adoption of a conceptual change and student focused approach to teaching is associated with perceptions that the teacher has control over what is taught and how it is taught, as well as perceptions that the department values teaching and that class size is not too large. CONCLUSIONS: The paper concludes by arguing that if we are to improve the quality of teaching and learning in higher education we will need to take account of the perceptions teachers have of their teaching context.

Whatever happened to delusional perception?

Thanks to the analysis of delusional perception's formal binary structure, generations of psychiatrists believed that the problem of delusion, at least from a descriptive point of view, had been resolved. The first-rank Schneiderian symptoms, and delusional perception in particular, had become reference points for the diagnosis of delusion and schizophrenia. Today, however, the phenomenon of delusional perception no longer seems to be taken into serious consideration by psychiatrists and psychopathologists. The crisis of the nosographic specificity of Schneiderian first-rank symptoms and the development of a transnosographic perspective in the study of delusion have definitively loosened the ties that existed in traditional psychopathology between delusional perception, delusion and schizophrenia. Despite the fact that delusional perception has lost its fundamental role in the nosographic sector, it still maintains its importance when studied in an interpersonal context. The significance of formal discontinuity evident in delusional perception authorized the psychiatrist to pause on the threshold of delusion without making allowances for the disastrous lack of comprehension so typical of delusional perception, which in turn must be studied from an interpersonal perspective, not as if it were an aseptic object in a laboratory. The therapeutic relationship can therefore provide an opportunity to recuperate those experiences which the patient was unable to store in his memory and concentrated in delusional perception.

Influence of cigarette smoking on the overall perception of dental health among adults aged 20-79 years, United States, 1988-1994.

OBJECTIVE: Investigation into the relationship between lifestyle factors (particularly cigarette smoking) and perceived oral health has been limited. Data from the third National Health and Nutrition Examination Survey (NHANES II), 1988-1994, were used to explore this relationship in a large sample of U.S. adults. METHODS: This study used data on 13,357 dentate participants in NHANES III aged 20-79 years. In NHANES III, information on perceived dental health, sociodemographic attributes, smoking status, frequency of dental visits, dental insurance, and general health perception were collected during a home interview, and oral health status was assessed at a mobile examination center. RESULTS: Overall, 34.4% of individuals in the study sample reported having an unfavorable perception of their dental health by qualifying it as "fair" or "poor." Furthermore, 46.6% of smokers had an unfavorable dental health perception, compared to 28.3% of non-smokers. An interaction between smoking and race/ethnicity was found in logistic regression modeling. Stratified results show that cigarette smoking was not a significant predictor for an unfavorable dental health perception among individuals who self-identified as Mexican American, but smoking was a significant predictor for an unfavorable dental health perception among those who identified as non-Hispanic black or non-Hispanic white. CONCLUSIONS: This is the first study to describe the effects of smoking on dental health perception while controlling for examined oral health status. Because perceived dental health is a potential indicator for dental care utilization, a better knowledge of the factors that influence dental health perception is not only important for dental services planning, but also for understanding oral health-related quality of life issues. Additionally, given that smoking may negatively affect dental health perception, these findings have potential implications for smoking cessation activities conducted by dental care providers.

The dynamic structure of relationship perceptions: differential importance as a strategy of relationship maintenance.

How do couples maintain relationship satisfaction despite specific negative perceptions of their relationships? One way to minimize the global implications of negative perceptions is to attribute differential importance to positive and negative features of the relationship. As those features change over time, satisfied intimates may alter their perceived importance, ensuring that positive features are always more closely associated with global satisfaction than negative ones. The current study examined the specific perceptions of 82 newly married couples at five assessments across their first 3 years of marriage. A tendency to view positive perceptions as more important than negative perceptions was associated with higher marital satisfaction. Moreover, a tendency to alter the importance of specific perceptions as those perceptions changed over time was associated with more stable global satisfaction. These findings highlight the interplay between the content and the structure of intimates' perceptions in determining relationship outcomes.

Nurses' perceptions of phase I clinical trials in pediatric oncology: a review of the literature.

A review of literature was conducted to explore nurses' perceptions of phase I clinical trials in pediatric oncology. Specifically, nurses' perceptions of the goals and outcomes, the nurse's role, and the informed consent process in pediatric oncology phase I clinical trials were investigated. Findings on possible factors influencing the nurses' perceptions and the quality of work-life of nurses working at pediatric phase I clinical trial centers were also searched. However, despite an extensive review of published works, no studies on nurses' perceptions of phase I trials in pediatric oncology were found. Therefore, this literature review consists of findings in similar or related studies such as nurses' perceptions of experimental therapies in the adult setting, adult patients' perceptions, parents' perceptions, or oncologists'perceptions of phase I clinical trials.

Patient and physician perceptions as risk factors for oligoanalgesia: a prospective observational study of the relief of pain in the emergency department.

OBJECTIVES: Previous studies have reported that pain is undertreated in the emergency department (ED), but few physician-dependent risk factors have been identified. In this study, the authors determine whether pain treatment and relief in ED patients are negatively associated with the physician's perception of whether the patient was exaggerating symptoms, and with the patient and physician's perceptions of the interaction between them, as well as whether demographic characteristics were associated with these perceptions. METHODS: This was a prospective observational study of patients who were undergoing treatment for painful disorders in the ED. Before treatment for pain, patients were asked to complete a 100-mm visual analog scale (VAS) describing their pain. Demographic information and pain treatments administered were recorded. Patients completed a second pain VAS before discharge from the ED. Patients were then asked to complete three queries describing their perception of their interaction with the physician. After the patient had left the department, the patient's physician was asked to complete a query describing his or her perception of the interaction and to complete a VAS describing how likely it was that the patient was exaggerating symptoms to obtain pain medicines for nonmedical purposes. RESULTS: There were 1,695 patients enrolled in the study; 32 patients were excluded because of missing or incomplete data, leaving 1,663 for analysis. Of these patients, 71.9% received a pain medication while in the ED. There was no association between the physician's VAS for perceived exaggeration of symptoms, the queries describing physician-patient interactions, and patient ethnicity and whether patients received pain treatment in the ED. There was a negative correlation between the physician's VAS for perceived exaggeration of symptoms and the change in the patient's pre- and posttreatment pain VAS scores. The physician's VAS score for perceived exaggeration of symptoms was higher among Native American patients than among other ethnic groups (p < or = 0.001). The patient and physician queries rating their interaction show a decreased absolute reduction of VAS pain scores (p > or = 0.001) and a reduction in the number of patients having at least a 50% reduction in their pain VAS score when interactions were rated "bad" and "very bad" (p < or = 0.001). CONCLUSIONS: The physician's perception of whether a patient was exaggerating symptoms was associated with the patient's ethnic background and with both the physician's and patient's perception of their interaction. These perceptions were negatively associated with the achievement of pain relief and the change in the patient's pain VAS scores, but not with whether a patient was treated with a pain medication.
