Development and psychometric evaluation of a self-administered questionnaire to measure knowledge of sexually transmitted diseases.

This research developed and evaluated a brief but comprehensive measure of knowledge about sexually transmitted diseases (STDs) for use in research and applied settings. Questionnaire construction involved a review of empirical precedents as well as qualitative work with STD experts (n = 6) and the target population (n = 40). Eighty-five items were piloted (n = 50) and tested (n = 391) with college students. Item- and test-level analyses identified items that were eliminated to shorten the questionnaire. Factor analyses revealed a two-factor model of STD knowledge, including a Cause/Cure factor and a General Knowledge factor. Six supplemental items were added to the final questionnaire for their public health value and resulted in the 27-item STD-Knowledge Questionnaire (STD-KQ). The STD-KQ demonstrated internal consistency (alpha = .86) and test-retest reliability (r = .88) over a brief period. Evidence for the validity of the STD-KQ was obtained through a comparison with a validated HIV knowledge questionnaire (Carey & Schroder, 2002); treatment outcome sensitivity was obtained in response to an educational program. Use of the STD-KQ will enable researchers and health educators to identify knowledge deficits, measure knowledge for theory testing, evaluate risk reduction programs, and assess treatment response in research and applied settings.

Smoking, health knowledge, and anti-smoking campaigns: an empirical study in Taiwan.

This paper uses a measure of health knowledge of smoking hazards to investigate the determinants of health knowledge and its effect on smoking behavior. In our analysis, two equations are estimated: smoking participation and health knowledge. The simultaneity problem in estimating smoking behavior and health knowledge is also considered. Overall, the estimated results suggest that anti-smoking campaigns have a significantly positive effect on the public's health knowledge, and this health knowledge in turn, has a significantly negative effect on smoking participation. The health knowledge elasticities of smoking participation are -0.48 and -0.56 for all adults and adult males, respectively.

Measuring knowledge of cancer.

At best, most individuals are able to recount two to three of the seven warning signs of cancer [1]. However, this finding is primarily based on free recall of symptoms personally experienced by the respondent. In the present study, a new approach is introduced as an alternative to traditional assessment of knowledge of cancer warning signs. The Knowledge of Cancer Warning Signs Inventory (KCWSI) is a 25 item self-report questionnaire which yields three scores concerning probability judgments about symptoms: basic recognition of the seven warning signs (BRCWS), the extent to which nonwarning signs are perceived to be warning signs (NSPWS), and the extent to which one can accurately discriminate between real and false positive warning signs (accurate knowledge of cancer: AKC). The KCWSI was given to a population who live in a community facing a perceived toxic waste hazard, based on the hypothesis that such a group should be cognizant of the warning signs of cancer because of the serious health threats posed by toxic exposure and the presumed need to engage in greater health preventative activities when living with such an environmental threat. Results show that basic knowledge of the seven cancer warning signs is predicted by AKC, fear of cancer, and a family history of cancer. Misperception of common distress symptoms (of anxiety, somatization, and depression) as symptoms of cancer (nonwarning signs perceived as warning signs: NSPWS) is predicted by fear of cancer, a composite scale of perceived susceptibility to cancer and other health-related problems, Global Symptom Distress, and higher order interactions among the demographic variables of race, gender, income and education. Accurate Knowledge of Cancer (AKC) is associated with lower fear of cancer and lower psychological distress than the other two knowledge measures. The Knowledge of Cancer Warning Signs Inventory yields complex information about how symptoms are perceived and may prove superior to other methods in understanding what people believe about the warning signs of cancer and how this understanding relates to health care behaviors. This study also illustrates the need to pay attention to how health information is measured.

Knowledge and attitudes about cancer pain management: a national survey of Italian oncology nurses.

The purpose of this study was to obtain information about the knowledge and attitudes of Italian oncology nurses concerning cancer pain management and to determine the predictors of nurses' pain management knowledge. The study was a nationwide descriptive survey and included 287 nurses in Italy from 21 oncology wards in the north, center and south of Italy. The Nurses' Knowledge and Attitudes Survey (Italian version) and a background information form were used to collect the data. Knowledge and attitudes regarding cancer pain were the main research variables. Among the 39 pain knowledge questions assessed, the mean number of correctly answered question was 21.4 (SD=5.5), with a range of 6-35. The correct answer rate for the entire scale, on average, was 55% (SD=25.9). Further analysis of items showed that more than 50% of oncology nurses underestimated the patients' pain and they did not treat it in the correct way; they also had an incorrect self-evaluation about their pain management knowledge. Results from stepwise regression showed that nurses with higher mean correct answer scores had attended more courses about pain education. There are still significant knowledge deficits and erroneous beliefs that may hamper treatment of oncology patients in pain. The results of this study could be useful to institutions involved in patient care and teaching of pain management.

The effects of prior knowledge on children's memory and suggestibility.

In this study, 5- and 6-year-olds were read a story and asked to recall its details. Two independent factors-prestory knowledge and poststory suggestions-were crossed to examine the effects on children's story recall. The results indicated that prestory social knowledge about the story protagonist as well as academic knowledge relating to the content of the story influenced the accuracy of children's recall immediately after the story presentation. Following the suggestive interview, children reported interviewer-provided social and academic misinformation to a greater extent when the misinformation was consistent with their prior knowledge. In contrast, children were more likely to refute misinformation that contradicted their academic knowledge. These findings are discussed in terms of the mechanisms underlying the knowledge-memory and knowledge-suggestibility linkages.

Use patterns and knowledge of medicinal species among two rural communities in Brazil's semi-arid northeastern region.

The present work seeks to quantify the knowledge of two rural communities in the semi-arid region of the state of Pernambuco (northeastern Brazil) concerning two species of native medicinal plants: "aroeira do sertão", Myracrodruon urundeuva (Engl.) Fr. All. (Anacardiaceae) and "angico", Anadenanthera colubrina (Vell.) Brenan (Mimosaceae). Semi-structured interviews were carried out, combined with a checklist/inventory method, which yielded different indexes for quantifying knowledge and use of these species. In addition, the reliability of local knowledge was tested using analytical techniques to determine actual tannin concentrations. Although both communities possess knowledge concerning these two species, one of them stood out in terms of the diversity of information presented (P < 0.05), a difference that may be related to its lower degree of modernization. In general, older people had a greater variety of information about these plants, although both men and women demonstrated similar knowledge. Of the 101 people interviewed in Riachão, 85% stated that they knew of uses for both species studied; in Ameixas, of the 55 interviewees, 63% responded that they knew of uses for Myracrodruon urundeuva, and 45% knew of uses for Anadenanthera colubrina. A total of 97 different uses were reported by all informants for the two species studied. Of these, 62 were mentioned in only a single community, confirming our hypothesis of differences in knowledge between them. Informants from both communities knew of a great variety of uses for these plants as well as a number of different collection techniques. We expected that knowledge about the two species would differ in relation to both gender and age, but this was only true for one of the communities. Greater concentrations of tannins were expected to be found consistently in the tree bark, but experimental data demonstrated that tannin concentrations can vary among plant parts during the year.

Development and validation of a Breast Cancer Genetic Counseling Knowledge Questionnaire.

Women who undergo genetic counseling concerning their increased risk of developing breast cancer confront large quantities of complex information in a short period of time. Clinical reports have suggested that many women may not retain what they learned during counseling. A validated questionnaire to measure their knowledge, however, is lacking. In this study, we describe the development and validation of a questionnaire to assess knowledge of information typically included in genetic counseling for breast cancer. Items were empirically derived from detailed content analyses of actual genetic counseling sessions. The instrument's content validity was high, as evidenced by high levels of independent interrater agreement (0.93) on items. Subsequent data reduction and confirmatory factor analytic techniques yielded a highly reliable (alpha = 0.92) 27-item Breast Cancer Genetic Counseling Knowledge Questionnaire (BGKQ). Direct comparison of this questionnaire to a scale previously developed in the literature (BCHK; [Breast Cancer Res. Treat. 53 (1999) 69]) supported the utility of the new questionnaire for evaluation of knowledge after counseling. Compared to non-counseled groups (n = 45), women who had undergone genetic counseling (n = 28) scored significantly higher (P < 0.0001) on the BGKQ, but not on the other questionnaire, establishing the BGKQ's criterion validity. The BGKQ may, thus, provide a useful clinical and research tool for assessing knowledge of information provided during genetic counseling and exploring the potential impact of distress on knowledge, as well as the impact of knowledge on screening behaviors.

Perceived genetic knowledge, attitudes towards genetic testing, and the relationship between these among patients with a chronic disease.

OBJECTIVE: Genetics increasingly permeate everyday medicine. When patients want to make informed decisions about genetic testing, they require genetic knowledge. This study examined the genetic knowledge and attitudes of patients with chronic diseases, and the relationship between both. In addition, patients were asked about their preferred source of genetic information. METHODS: Questionnaires were mailed to participants of a nationwide representative sample of patients with chronic diseases in the Netherlands (n = 1916). RESULTS: The response rate was 82% (n = 1496). Perceived genetic knowledge was low, particularly among older and lower educated patients. Attitudes towards genetics were rather positive, especially among younger and higher educated patients. Some concerns were also documented, mainly about the consequences of genetic testing for employment and taking insurance. Patients who perceived to have little knowledge found it difficult to formulate an opinion about genetic testing. Higher levels of genetic knowledge were associated with a more favourable attitude towards genetics. Chronic patients prefer to receive genetic information from their GP. CONCLUSION: Chronic patients are ill prepared when they require genetic knowledge to make decisions regarding the treatment of their disease. This seems to result from a knowledge deficiency rather than from disagreement with the genetic developments. PRACTICE IMPLICATIONS: When chronic patients are in need of information about genetics or genetic testing, their general practitioner should provide this.

A comparison of traditional healers' medicinal plant knowledge in the Bolivian Andes and Amazon.

Medicinal plant knowledge of two groups of traditional healers was thoroughly studied during a 2-year ethnobotanical survey in the Bolivian Andes (Quechua farmers from Apillapampa) and Amazon rainforest (Yuracaré-Trinitario slash-and-burn cultivators from Isiboro-Sécure National Park), respectively. Both areas represent ecologically and culturally diverse zones, differing in floristic diversity, physical accessibility to health care and degree of modernization, the latter evidenced by presence or intensity in use of modern services such as electricity, water distribution, and materials for house construction. It is generally believed that indigenous people have an impressive knowledge of useful plant species and that this knowledge reflects the plant wealth of their living environment. However, the present study shows that healers' knowledge of collected medicinal plants (expressed as percentage of plants known by name and use by the majority of healers) is higher in the Andean area characterised by a long history of anthropogenic activity, than in the biodiversity-rich rainforest (protected since 1965). Therefore, medicinal plant knowledge does not seem to depend on the level of plant diversity, degree of modernization or absence of Western health care infrastructure. Indeed, although Andean healers live in a floristically poorer environment, have adopted more modern services and have easier access to primary health care facilities, they are more knowledgeable about medicinal plants than rainforest healers who live isolated in an environment with considerable floristic/ecological variation and lack of Western health care. It is hypothesised that social factors underlying traditional medical practices (background of extensive family in traditional medicine) play an important role in transmission--and hence survival of knowledge on medicinal plants.

Assessing medical student knowledge, attitudes, and behaviors regarding organ donation.

PURPOSE: To measure medical students' knowledge of the central issues in organ donation and transplantation and to understand their perception of the extent of training they received prior to and during medical school. METHODS: A previously validated, 41-question instrument assessing organ donation, allocation, and transplantation knowledge was directly administered to 537 first- and second-year medical students attending one of three Ohio schools from January through April 2005. Students were also asked about their support for organ donation and the donation training they had received. RESULTS: Two hundred sixty four first-year and 236 second-year students responded (response rate = 93%). Few students to date received donation and transplantation training before (11%) or during (22%) medical school. Second-year students were more likely than first-year students to have received training during medical school (40% vs 6%, P < .001) and to have read articles regarding donation (24% vs 15%, P = .017). However, both first- and second-year medical students answered the majority of the knowledge questions incorrectly (43% vs 48%, P < .002). Knowledge regarding brain death was lower among medical students compared to a random sample of Ohio adults (P < .001). Donation coursework prior to or during medical school was significantly associated with an increased knowledge regarding donation (odds ratio [OR] = 2.01, P = .001) and knowing where to find answers to patients' questions regarding donation (OR = 2.76, P < .001). CONCLUSION: Medical students have significant gaps in knowledge regarding the organ donation and transplantation system. Donation and transplantation education is associated with improved knowledge in the area and comfort in knowing how to address patient questions.

Zambian health care workers' knowledge, attitudes, beliefs, and practices regarding epilepsy.

OBJECTIVE: Zambia suffers from a physician shortage, leaving the provision of care for those with epilepsy to nonphysician health care workers who may not be adequately trained for this task. These individuals are also important community opinion leaders. Our goal in this study was to determine the knowledge, attitudes, beliefs, and practices of these health care workers with respect to epilepsy. METHODS: Health care workers in urban and rural districts of Zambia completed a self-administered, 48-item questionnaire containing items addressing demographics, personal experience with epilepsy, social tolerance, willingness to provide care, epilepsy care knowledge, and estimates of others' attitudes. Analyses were conducted to assess characteristics associated with more epilepsy care knowledge and social tolerance. RESULTS: The response rate was 92% (n=276). Those who had received both didactic and bedside training (P=0.02) and more recent graduates (P=0.007) had greater knowledge. Greater knowledge was associated with more social tolerance (P=0.005), but having a family member with epilepsy was not (P=0.61). Health care workers were generally willing to provide care to this patient population, but approximately 25% would not allow their child to marry someone with epilepsy and 20% thought people with epilepsy should not marry or hold employment. Respondents reported that people with epilepsy are feared and/or rejected by both their families (75%) and their community (88.8%). CONCLUSIONS: Knowledge gaps exist particularly in acute management and recognition of partial epilepsy. More recent graduates were more knowledgeable, suggesting that curriculum changes instituted in 2000 may be improving care. Health care workers expressed both personal and professional reservations about people with epilepsy marrying. In addition to improving diagnosis and treatment skills, educational programs must address underlying attitudes that may worsen existing stigmatizing trends.

The associations between knowledge, CA125 preoccupation, and distress in women with epithelial ovarian cancer.

OBJECTIVE: The goal of the current study was to determine how much women with ovarian cancer know about their cancer and CA125 testing and how much women focus on or are preoccupied with their CA125 levels. We also examined the direct and moderating effects of knowledge and CA125 preoccupation on two measures of distress (depressive symptoms and anxiety). METHODS: Participants were 126 women with epithelial ovarian cancer. Patients completed questionnaires of knowledge, CA125 preoccupation, and distress at the beginning of the first or a new round of chemotherapy. RESULTS: Both knowledge and preoccupation with CA125 levels were associated with depressive and anxiety symptoms. More importantly, knowledge appeared to moderate the association between CA125 preoccupation and depressive symptoms. That is, for patients with lower levels of knowledge, more CA125 preoccupation was associated with more depressive symptoms. However, there was no such association in women with higher levels of knowledge. CONCLUSION: Our results suggest that it may be possible to decrease depressive symptoms in women who are overly preoccupied or worried about their CA125 levels by improving their knowledge of aspects of their disease and the surveillance process.

Appropriate antibiotic use: variation in knowledge and awareness by Hispanic ethnicity and language.

BACKGROUND: Recent campaigns are informing the public that antibiotics are inappropriate for viral respiratory infections. As little is known about their effect on populations challenged by less access to care, lower education, low income, low English proficiency, or non-mainstream cultural backgrounds, this study assessed knowledge, attitudes, and awareness in an ethnically diverse community. METHODS: A telephone survey in English or Spanish of a cross-sectional, random sample of 692 non-Hispanic whites (NHWs) and 300 Hispanics in Colorado. RESULTS: For all respondent groups, knowledge of appropriate antibiotic use for colds and bronchitis was low. Hispanics surveyed in Spanish, compared with non-Hispanic whites, had significantly lower knowledge about antibiotics for colds, higher knowledge for bronchitis, lower awareness about antibiotic resistance, and greater dissatisfaction if an antibiotic were not prescribed. In all comparisons, English-language Hispanics tended to reflect non-Hispanic white response patterns. Independent predictors of awareness were ethnicity, education, and age. Independent predictors of dissatisfaction were ethnicity, knowledge about antibiotic use for colds, and bronchitis. Ethnicity was an independent predictor of knowledge about the inappropriateness of antibiotics for colds and bronchitis. CONCLUSIONS: To bridge knowledge gaps, educational campaigns for all segments of the population are needed. Content should be responsive to heterogeneity within populations.

Knowledge, attitudes, and behaviors of college students regarding the 1990 Nutrition Labeling Education Act food labels.

OBJECTIVES: This study examined the influence of 1990 Nutrition Labeling and Education Act food labels on college students. The purposes of the study were to examine knowledge, attitudes, and behaviors of college students regarding labels and relationships among these factors, and whether educational experience with labels was associated with label-reading knowledge, attitudes, and behaviors. DESIGN: A descriptive, nonexperimental research design was used. Data were gathered using a survey designed for the study. SUBJECTS: The study surveyed 208 undergraduate students enrolled in general education classes at a midwestern university. STATISTICAL ANALYSIS: Descriptive statistics analyzed knowledge, attitudes, and behaviors of college students regarding food labels. The Student t test and chi 2 analysis evaluated specific measures of behavior. Pearson correlation coefficients and multiple regression analysis examined relationships among variables and identified factors associated with label use. RESULTS: Students' mean knowledge score was 48%. Knowledge score was positively correlated with attitudes toward labels (r = .14, P = .04) and use of labels (r = .87, P = .0001). Previous education in reading labels was associated with higher knowledge scores (P = .04). Ninety-five percent of participants perceived the label to be useful, but many distrusted nutrition claims. Seventy percent looked at the Nutrition Facts label when purchasing a product for the first time. The single best predictor of general label use was a positive attitude toward labels (P < .001), followed by being a woman (P < .01). CONCLUSIONS: The 1990 National Labeling and Education Act food label has influenced college students. Labeling education efforts are associated with greater knowledge about labels, more favorable attitudes toward them, and increased label use in making food choices. Special attention should be directed toward explaining terms and phrases on labels and the guidelines that ensure truthfulness of nutrition claims. College students need to understand their need for numerous nutrients instead of merely focusing on the fat and caloric content of foods.

Education and certification influence the nutrition and management knowledge of long-term-care foodservice managers.

OBJECTIVES: To describe nutrition knowledge, attitude toward nutrition, and management knowledge of long-term-care foodservice managers and to determine the relationship between these variables and the foodservice managers' personal and facility characteristics. DESIGN: Nutrition knowledge, management knowledge, and attitudes toward nutrition were measured using survey methodology designed for this study by modifying an instrument developed by the Nutrition Education Training Program for the Texas Department of Human Services. SUBJECTS/SETTING: Surveys were mailed to a random sample of 300 long-term-care foodservice directors from the 1,092 directors listed in the 1996 Ohio Department of Health Directory of Nursing Homes. The participants were 123 of the 300 foodservice directors (41%). STATISTICAL ANALYSES PERFORMED: Descriptive statistics, Spearman rank correlations, 1-way analysis of variance, and post hoc variance were calculated. RESULTS: Mean scores of respondents were 21.2 out of a possible 29 (73%) for the nutrition knowledge assessment, and 18.2 out of 26 (70%) for management knowledge. Dietitians and dietetic technicians scored significantly better than others on these tests. The mean score of attitudes toward nutrition was 4 on a 5-point scale (where 1 = strongly disagree to 5 = strongly agree). All participants requested more training in computers, nutrition terminology, and preparing appealing foods. APPLICATIONS: Dietitians and dietetic technicians are prepared with a wide scope of knowledge in nutrition and management. Thus, they are in an ideal position to take advantage of job opportunities in the area of foodservice management.

Balancing the curriculum: promoting aesthetic knowledge in nursing.

The view of nursing as both art and science is widely held within the profession; however, this belief is not reflected in nurse education where the artistic aspects of nursing practice continue to be overshadowed by the emphasis on the scientific, the technical and the objective. It is suggested that nursing knowledge can be considered within four fundamental types or patterns of knowledge: empirical, aesthetic, personal and moral, each interrelated and interlinked, with aesthetic knowledge argued to encompass the art of nursing. Nursing's dual identity as an art and science arguably requires a balance within the curriculum, therefore the promotion and acquisition of aesthetic knowledge seems a desirable aim. The development of strategies specifically designed to develop and incorporate such knowledge across the curriculum and to make it explicit presents a challenge for all nurse educators. This paper will examine aesthetic knowledge as essential to the art of nursing, and will consider the application of literature as a method through which this knowledge may be attained. The use of literature is suggested as facilitating an awareness of human predicaments universal to all, thus enabling the nurse to develop qualities of caring, empathy and compassion, indicated to be components of nursing's art form.

Practical logics: the shapes and lessons of popular medical knowledge and practice--examples from Vietnam and Indigenous Australia.

Popular medical knowledge and practice exist in forms that people are able to remember, and that they use to manage their daily lives. This knowledge is fundamentally practical and relates to the patterns of everyday life and the rhythms of the body. The broad "polythetic" concepts of this knowledge system are typically drawn from both dominant and other medical knowledges, and combined in pragmatic, mnemonic ways that constitute a hybrid system. Such popular medical knowledge is attuned to local, family and cultural patterns of medical and other authority, and to the personal dispositions and environmental contexts of its users. Health promoters and educators who understand these formal, embodied and familiar dimensions of popular knowledge can potentially mimic this knowledge system, making their interventions a sustainable part of everyday family life.

The role of knowledge and beliefs in help seeking behaviour for cancer: a quantitative and qualitative approach.

The study involved quantitative methods to assess the relationship between knowledge about cancer related symptoms and help seeking behaviour and qualitative methods to explore the role of patient's beliefs about cancer in explaining the gap between knowledge and behaviour. Patients (288) (response rate 72%) from one urban general practice completed a questionnaire consisting of 25 symptoms which they rated for whether they were cancer symptoms (knowledge) and whether the symptoms would prompt them to visit the doctor (hypothetical help seeking behaviour). Twenty patients were then selected who represented a range of knowledge levels and help seeking behaviour and interviewed about their beliefs about cancer. The results showed that the majority of patients had fair knowledge and appropriate help seeking behaviour and indicated a significant association between these variables. However, this relationship was not absolute and although significant the correlation was low. Accordingly, although the subjects knew which symptoms were indicative of cancer, this knowledge was not entirely predictive of their help seeking behaviour. The interviews provided insights into the beliefs which may explain the knowledge/behaviour gap. In particular, analysis of the interviews indicated that the interviewees represented cancer in terms of feelings of fear and death, that they described the process of symptom recognition as involving a fear of finding out the truth, they regarded screening programmes as something to be avoided and understood the causes of cancer either in terms of personal behaviour and internal causes which may result in recriminations or external causes which were beyond their control. The results are discussed in terms of the role of beliefs in mediating the association between knowledge and behaviour and the possible implications for developing educational programmes.
