Understanding perceptions of HIV risk among adolescents in KwaZulu-Natal.

Risk perception has been theorized to be an important antecedent for adopting protective behavior. It is a key construct of research applying the Health Belief Model and other behavior change models. In relation to HIV, risk perception is an indicator of perceived susceptibility to infection, a measure for one's understanding of AIDS transmission as well as willingness to consider behavioral changes. However, there remains much we do not know about what drives risk perception, especially among youth. This study identifies factors that influence the calculation of HIV-risk perception among a group of adolescents in South Africa. Data, collected in 1999 from 2,716 adolescents aged 14-22, are used to explore factors predicting risk perception. Logistic regression models suggest connectedness to parents and community for males and females, self-efficacy to use a condom among males, and living in a household with a chronically ill member for females are associated with HIV risk perception. We conclude that a greater understanding of the connection of adolescents to their communities and adults in their lives is needed, and ways in which programs can alter the environments in which adolescents form opinions, make choices, and act should be incorporated into program design.

Relapse and risk perception among members of a smoking cessation clinic.

Assessed perceptions of the health risks associated with smoking in comparison with not smoking among members of smoking cessation clinics. We measured these perceptions at three different time periods during the clinic, and then again at a 6-month follow-up. Results indicated that members who were abstinent at the follow-up had lowered their perceptions of the likelihood of contracting smoking-related illnesses (e.g., emphysema) if they were not smoking. In contrast, those who had relapsed lowered their perceptions of the health risks associated with smoking, but not their perceptions of nonsmoking disease vulnerability. The implications of these changes in risk perception for therapy involvement are discussed.

Differential parental treatment predicts achievement and self-perceptions in two cultural contexts.

This study examined 148 Asian American and European American late adolescents' perceptions of differential affection and control by mothers and fathers as predictors of academic achievement and self-perceptions of intellectual ability and global self-worth. Overall, analyses generally confirmed the hypotheses that the more differentially favorable the treatment (more affection or less control) or the less differential treatment (above and beyond which sibling was favored) reported in the home, the more positive late adolescents' outcomes. Perceptions of differential parental treatment predicted up to 13% of the variance in achievement and self-perceptions. Several findings were moderated by ethnicity or gender. Finally, and perhaps most importantly, perceptions of differential parental treatment predicted a significant and unique amount of variance in outcomes beyond that predicted by perceptions of absolute levels of affection and control.

Symptom perception in childhood asthma: the role of anxiety and asthma severity.

This study tested the relationship of anxiety and asthma severity to symptom perception. Eighty-six children diagnosed with mild or moderate asthma had symptom perception and pulmonary function measured throughout methacholine challenge (to induce bronchoconstriction). Higher trait anxiety was associated with heightened symptom perception (controlling for pulmonary function) at baseline. Greater asthma severity was associated with blunted symptom perception (controlling for pulmonary function) at the end of methacholine challenge and with a slower rate of increase in symptom perception across methacholine challenge. These results suggest that anxiety plays a role when children's symptoms are mild, whereas medical variables such as severity play a role in perception of changes in asthma symptomatology as bronchoconstriction worsens.

Perceptions of local neighbourhood environments and their relationship to childhood overweight and obesity.

OBJECTIVES: To examine associations between parent and child perceptions of the local neighbourhood and overweight/obesity among children aged 5-6 and 10-12 y. DESIGN: Cross-sectional survey. SUBJECTS: In total, 291 families of 5-6-y-old and 919 families of 10-12-y-old children. MEASURES: Parent's perceptions of local neighbourhood and perceived child access to eight local destinations within walking distance of home; 10-12-y-old children's perception of local neighbourhood; socio-demographic characteristics (survey). Children's height and weight (measured). RESULTS: No perceptions of the local neighbourhood were associated with weight status among 5-6-y-old children. Among 10-12-y-old children, those whose parents agreed that there was heavy traffic in their local streets were more likely to be overweight or obese (OR=1.4, 95% CI=1.0-1.8), and those whose parents agreed that road safety was a concern were more likely to be obese (OR=3.9, 95% CI=1.0-15.2), compared to those whose parents disagreed with these statements. CONCLUSIONS: This study suggests that parental perceptions of heavy traffic on local streets and concern about road safety may be indirect influences on overweight and obesity among 10-12-y-old children. Future work should also consider perceptions of the neighbourhood related to food choice.

Compliance with hand therapy programs: therapists' and patients' perceptions.

AIM: This study explored patients' and hand therapists' perceptions of compliance with hand therapy and compared these perceptions. METHOD: Forty-one patients attending hand therapy at a large metropolitan hospital and 69 hand therapists, all members of the Australian Hand Therapy Association, were interviewed by telephone using a questionnaire developed for the study. Demographic data were analyzed descriptively and patients' and therapists' perceptions compared using chi-square. RESULTS: Patients' and therapists' perceptions differed at a statistically significant level (p < 0.01, adjusted alpha rate) for 24 of the 33 items measuring perceptions of compliance with hand therapy. CONCLUSIONS: Therapists and patients have differing perceptions of compliance.

Airway responsiveness as a direct factor contributing to the dyspnoea perception in asthma.

It is not clear whether airway responsiveness is directly related to the perception of bronchoconstriction in asthma. The purpose of this study is to directly compare the perception of induced bronchoconstriction among the groups classified according to the degree of airway responsiveness. Two hundred and twenty-seven patients with the definitive or suspected asthma underwent a methacholine provocation test. During the test, the degree of dyspnoea was assessed by a modified Borg scale. The perception of induced bronchoconstriction was indicated by the slope in the linear regression analysis between changes in Borg score and the reduction in forced expiratory volume in 1 sec (FEV1) as a percentage of baseline value. The provocative concentration of methacholine resulting in 20% fall in FEV1 (PC20) was calculated. The degree of airway responsiveness to methacholine was categorized as moderate to severe airway hyper-responsiveness (AHR) if PC20 was < 1 mgml(-1), mild AHR if PC20 was > or =1 but < or =4 mgml(-1), borderline AHR if PC20 was >4 but < or =16 mgml(-1), and normal airway responsiveness (negative AHR) if PC20 was > 16 mgml(-1). Positive AHR was defined as PC20< or =4 mgml(-1). Another index of bronchial responsiveness (BR index) was calculated as the log [(% decline in FEV1/log final methacholine concentration as mg dl(-1)+10]. We found that the geometric mean of the slope was lower in subjects with positive AHR (0.12, n=115) than in subjects with negative AHR (0.17, n=72; P<0.01). The geometric mean of the slope in subjects with borderline AHR (0.14, n=40) was between the two groups. Furthermore, the slope was decreased in asthmatics with moderate to severe AHR compared with mild AHR (P <0.05), although the baseline FEV1 did not differ between the two groups. In multiple regression analysis, airway responsiveness expressed as BR index had a significant effect on the perception of bronchoconstriction. We conclude that the perception of bronchoconstriction is diminished in patients with AHR and the degree of airway responsiveness may be directly related to the perception of bronchoconstriction in asthmatic subjects.

The effects of test difficulty on undergraduates' state anxiety and perception of test difficulty.

The finding of a previous study that student perception of difficulty level may be just as important as the actual difficulty levels was reinterpreted. A specially developed Educational Psychology Recognition Test and Test Perception Inventory assessed task difficulty and perception of exam difficulty, respectively, in 30 American undergraduates. A modified version of the State-Trait Anxiety Inventory assessed state anxiety. Results indicated, that 1) test difficulty did not significantly affect state anxiety but did significantly affect perception of exam difficulty, 2) students administered the high-difficulty test exhibited a perception of higher exam difficulty than those taking the medium- and low-difficulty tests, and 3) there was no significant difference for the perception of exam difficulty between students taking the medium- and low-difficulty tests.

Resources and estuarine health: perceptions of elected officials and recreational fishers.

It is important to understand the perceptions of user groups regarding both the health of our estuaries and environmental problems requiring management. Recreational fishers were interviewed to determine the perceptions of one of the traditional user groups of Barnegat Bay (New Jersey), and elected officials were interviewed to determine if the people charged with making decisions about environmental issues in the bay held similar perceptions. Although relative ratings were similar, there were significant differences in perceptions of the severity of environmental problems, and for the most part, public officials thought the problems were more severe than did the fishers. Personal watercraft (often called Jet Skis) were rated as the most severe problem, followed by chemical pollution, junk, overfishing, street runoff, and boat oil. Small boats, sailboats, wind surfers, and foraging birds were not considered environmental problems by either elected officials or fishermen. The disconnect between the perceptions of the recreational fishers and those of the locally elected public officials suggests that officials may be hearing from some of the more vocal people about problems, rather than from the typical fishers. Both groups felt there were decreases in some of the resources in the bay; over 50% felt the number of fish and crabs had declined, the size of fish and crabs had declined, and the number of turtles had declined. Among recreational fishers, there were almost no differences in perceptions of the severity of environmental problems or in changes in the bay. The problems that were rated the most severe were personal watercraft and overfishing by commercial fishers. Recreational fishers ranked sailboats, wind surfers, and fishing by birds as posing no problem for the bay. Most fishers felt there had been recent major changes in Barnegat Bay, with there now being fewer and smaller fish, fewer and smaller crabs, and fewer turtles. The results suggest that the views of a wide range of coastal users should be considered when making environmental health decisions.

Perceptions of the educational environment of the medical school in King Abdul Aziz University,saudi Arabia.

The present paper reports data from the undergraduate medical school at King Abdul Aziz University in Saudi Arabia using the 50-item Dundee Ready Education Environment Measure (DREEM), which has been validated and found to be reliable in a range of cultural contexts. The mean total score was 102/200. The mean total score for Perception of Learning was 22/48; for Perceptions of Teaching 24/44; for Academic Self-perceptions 17/32; for Perceptions of Atmosphere 23/48 and for Social Self Perceptions 15/28. The mean score of 0.9 for Item 3--There is a good support system for students who get stressed--was the lowest and is indicative of the pressures felt by the students. These scores give a clear indication of the priorities for reform of the curriculum. These data can also serve as a baseline for a longitudinal quality assessment of students' perceptions of the changes planned for the medical school at King Abdul Aziz University, Saudi Arabia. Further studies are needed to analyse educational environment down to the year levels and to detect any gender differences.

Relationships among children's beliefs, perceptions of their parents' beliefs, and their moderate-to-vigorous physical activity.

The purposes of this study were to (a) examine the relationship between children's beliefs (value, competence, and goal orientations) pertaining to fitness-oriented activities and their participation in moderate-to-vigorous physical activity (MVPA), (b) determine whether children's own beliefs are related to their perceptions of their parents' beliefs about them (value, competence, goal orientations, expectancies), and (c) examine the relationship between children's perceptions of their parents' beliefs and their MVPA. Self-report questionnaires and structured interviews were administered to children (N = 81, ages 11-15) in a one-on-one situation in their homes to tap their own beliefs, their perceptions of their parents' beliefs, and to assess children's level of MVPA through the use of two-day recall and peer comparison measures. Multivariate multiple-regression analyses revealed that children's beliefs about their MVPA could predict a significant amount of the variance in their self-reported MVPA and that children's perceptions of their parents' beliefs were unrelated to their MVPA. Follow-up canonical correlation analyses showed that the most significant and positive predictors of MVPA were children's perceptions of competence and the degree to which they endorse a task and ego orientation. S second multivariate multiple-regression analysis revealed that children's perceptions of their parents' beliefs about them and their own beliefs about MVPA were significantly related. These findings are discussed within the framework of a Family Influence Model for understanding children's MVPA participation.

Patient perception of quality following a visit to a doctor in a primary care unit.

BACKGROUND: Assessment of the quality of primary care services may be enhanced by including patient perceptions as well as professional judgment of quality. There is a need for reliable and valid instruments to measure these perceptions. OBJECTIVES: (i) To present a scale for measuring patient perception of quality of care following a visit to a doctor; and (ii) to analyse the responses given by patients recruited in primary care units in the Montreal region. The scale is composed of 22 items regrouped into three sub-scales referring to the patient-physician relationship (five items); the technical aspects of care (12 items); and the outcomes of the visit (five items). Distinctive features of the scale are that it focuses on patients' opinions about quality rather than on satisfaction, and that it includes items related to outcomes of the visit. METHODS: A survey was conducted on 473 patients who visited a physician in 11 primary care units in the Montreal region. Randomly selected patients received mailed questionnaires 5-7 days following their visit. Various statistical procedures were used to assess the reliability and the validity of the global scale and the sub-scales, and to analyse patients' patterns of response. RESULTS: The analysis of the psychometric properties of the global scale and the three sub-scales provides favourable evidence concerning their reliability and validity. The results of the factor analysis, the inter-item correlations and the Cronbach's alpha coefficients all support the distinction made between the interpersonal processes, the technical processes and the outcomes, and, at the same time, confirm the complex nature of the notion of perceived quality. The analysis of patients' responses allows the identification of items associated with global perception about quality of care. This global perception results from patients' perception of the physician's professional and interpersonal skills as well as from the outcomes of care. CONCLUSION: The scale can be used by physicians or primary health care units and has a wide range of applications.

Change in health risk perception following community intervention in Central Havana, Cuba.

It is increasingly recognized that individual values, beliefs and behavior operate within a social context. There is growing consensus that local perceptions and indigenous knowledge should be important elements in the evaluation of programs aimed at improving health. Thus, an assessment of changes in health risk perception was included in the evaluation of a multi-component intervention project undertaken between 1996 and 1999 aimed at improving the health and well-being of residents in the inner city community of Cayo Hueso, in Centro Habana, Cuba. The community intervention involved a tremendous mobilization of government and non-governmental organizations, to promote social and cultural activities and address deficiencies in housing, water supply, waste disposal and street illumination. Prior to the interventions, 365 adults were surveyed regarding their perceived health risks regarding 41 health determinants, scored on four-point Likert scales ranging from 'without risk' to 'very risky'. A factor analysis of these data classified perception of risk into five areas: social environment, threats to personal health, lifestyle choices, environmental sanitation and housing conditions. The objective of the current analysis was to determine if there were changes in the level of perceived risk to health over the 5 years pre- versus post-intervention in Cayo Hueso, and if so, whether these changes were significantly different from changes seen during the same 5-year period in Colón, another community in Centro Habana not receiving focused interventions. During the first quarter of 2001, 1703 individuals living in 654 households in Cayo Hueso and Colón were interviewed in their homes using an enhanced version of the 1996 risk perception instrument. Ordinal logistic regression models, adjusted for age, gender and years of education, were fit to assess change in health risk perception between 1996 and 2001. Significant declines in perceived health risk were found in both Cayo Hueso and Colón within all five domains, with significantly greater declines in many areas in Cayo Hueso compared with Colón, particularly with respect to housing-related health risks, indeed the main target of the intervention. Risk perception surveys are useful characterizations of widely held views in a target population. Our findings of decreased perceived health risk following public health, physical and social interventions to improve health suggests that this line of inquiry merits consideration in planning evaluations of multi-sectoral community-based health promotion interventions.

Effect of field experiences on music therapy students' perceptions of choral music for geriatric wellness programs.

The purpose of the study was to examine the effect of field experiences on music therapy students' perceptions of choral music for geriatric wellness programs. Specifically, the study investigated music therapy students': a) personal comfort working with senior adult singers; b) perceptions of preparation in their educational training to work with senior adults in a choral music wellness program; c) perceptions of senior adults' functioning levels as singers in choral ensembles; d) perceptions of senior adults' functioning levels as learners; and e) willingness to seek additional opportunities to lead senior adults in choral music wellness programs. Comparative analysis using pretest and posttest scores for each grouping was completed. Significant mean score differences were found in the categories of student comfort, preparation, perceptions of singing, and willingness, with gains from pre- to posttest in all categories. The general demographics and perceptions of learning groupings increased and decreased, respectively, though not significantly, following the field experience. Analysis combining all groups, creating an overall pretest and posttest score, was also completed. Results revealed that students felt significantly more positive about choral music being used in wellness programs for senior adults after the field experience.

Children's risk taking behaviors: the role of child-based perceptions of vulnerability and temperament.

OBJECTIVE: To examine the relationship between perceptions of vulnerability, temperament, and children's risk taking behavior in a simulated home environment. METHODS: Children and their primary caregivers were interviewed regarding temperament and perceptions of vulnerability to injury. In addition, children's interactions with simulated hazards were observed in an environment representing a typical home. RESULTS: Children whose caregivers reported higher levels of activity were significantly more likely to report lower perceptions of vulnerability to injury and show increased risky behavior. After controlling for gender differences, children's risky behaviors were predicted from child-based perceptions of vulnerability. CONCLUSION: Perceptions of vulnerability and active temperaments represent significant risk factors for potential injuries in the home. Modifying perceptions of vulnerability as well as identifying at-risk temperaments for injuries is important to consider when developing effective interventions.

Changes in students' perceptions of the professional role.

The purposes of this study were to determine whether students' perceptions of the role of the physical therapist and of themselves in that role change during a two-year entry-level postbaccalaureate degree program in physical therapy, when these changes occur, and the differences between students' perceptions and those of their faculty members. A semantic differential test was completed by 14 entry-level postbaccalaureate degree students five times during the two-year program. Sixteen faculty members completed the same test twice. Perceptions relating to five concepts of the professional role of the physical therapist and to five concepts relating to self in that role were assessed. Kendall's coefficient of concordance revealed no significant change in the students' perceptions of the role of the physical therapist, but it did reveal a significant change in one of the five concepts relating to their perceptions of themselves in that role (p less than .05). A Mann-Whitney U test revealed significant differences between the students' and faculty members' perceptions for 5 of the 10 concepts. Results of the study provide information about the professional socialization of physical therapy students.

Physical therapists' perceptions of the roles of the physical therapist assistant.

BACKGROUND AND PURPOSE: This longitudinal study investigated physical therapists' perceptions of the roles of physical therapist assistants (PTAs). METHODS AND SUBJECTS: In 1986, a questionnaire describing 79 physical therapy activities was distributed to a random sample (n = 400) of physical therapists derived from the American Physical Therapy Association (APTA) membership. In 1992, a similar questionnaire was distributed to a representative sample (n = 400) of physical therapists derived from the APTA membership. Response rates were 53% and 55% in 1986 and 1992, respectively. Respondents indicated whether each activity was included in the documentation describing PTA roles. RESULTS: Results revealed considerable agreement between therapists' perceptions of PTA roles and those outlined by PTA practice guidelines, and these perceptions changed little over time. Discriminant analyses suggested that therapists' perceptions of PTA roles were, in general, not predicted by supervisory experience with PTAs, therapist experience, or content of entry-level professional education curricula. CONCLUSION AND DISCUSSION: Generally, therapists' perceptions of PTA roles are consistent with published practice guidelines. Therapists' perceptions on selected activities, however, were incongruent with PTA practice guidelines, suggesting the potential for inefficient or inappropriate utilization of the PTA in the delivery of selected services.

Effects of cognitive arousal and physiological arousal on sleep perception.

STUDY OBJECTIVES: Two experiments were conducted to investigate the effect of presleep arousal on sleep perception. Experiment 1 examined the link between presleep cognitive arousal and distorted perception of sleep and compared the relative effect of anxious and neutral cognitive arousal on sleep perception. Experiment 2 compared the relative effect of anxious cognitive arousal and physiological arousal on sleep perception. DESIGN: Participants completed a nap session. Just prior to the nap, the participants were randomly assigned to 1 of 3 groups to receive different arousal manipulations. They were then allowed to go to sleep and were asked to report their sleep perception upon waking. SETTING: Sleep laboratory. PARTICIPANTS: Fifty-four healthy good sleepers in each experiment. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Self-reported sleep, actigraphy-defined sleep, and the discrepancy between them were indexed. In Experiment 1, participants who were experimentally manipulated to experience anxious cognitive arousal during the presleep period reported longer sleep-onset latency. Both the Anxious Cognitive Arousal Group and the Neutral Cognitive Arousal Group exhibited a greater discrepancy between self-reported and actigraphy-defined sleep, relative to participants who received no manipulation. In Experiment 2, participants who were experimentally manipulated to experience anxious cognitive arousal or physiological arousal during the presleep period reported longer sleep-onset latency and shorter total sleep time, and both groups exhibited a greater discrepancy between the self-reported and actigraphy-defined sleep, relative to participants who received no manipulation. CONCLUSIONS: Results suggest that both presleep cognitive arousal and presleep physiological arousal contribute to distorted perception of sleep.
