Exploring Youth Perceptions About Cancer Prevention and Preferences for Education: a Qualitative Study

This study aimed to characterize adolescents' perspectives on cancer and cancer prevention and to explore their preferences for cancer education. A total of 188 middle and high school students participated in 25 focus groups. Focus groups were led by study team members and included five to ten participants each. Adolescents were asked to discuss their cancer and cancer prevention knowledge, sources of cancer education, and preferences for cancer prevention education. Focus groups were audio-recorded, and professionally transcribed. Transcripts were content and thematically analyzed by two study team members using NVivo qualitative data software. Six themes were identified in focus groups: knowledge about cancer, negative perceptions of cancer, awareness of cancer prevention, engagement in cancer prevention, facilitators and barriers for action, and preferences for cancer education. Adolescents described a wide range of cancer education sources, including friends, family, healthcare professionals, school, technology, and pamphlets. Participants associated cancer with negative emotions, such as sadness and fear. Participants expressed interest in learning about cancer and cancer prevention, but also identified barriers to engaging in preventative behaviors, such as discomfort, lack of knowledge, and lack of personal connection to cancer. Adolescents preferred learning through personal presentations, online videos, school, educational games, and social situations. Adolescence is a critical period for learning and developing healthy behaviors. Awareness of cancer and cancer prevention is crucial to lowering cancer risk in the future. To be effective, cancer education for adolescents should target specific areas of cancer prevention and address barriers to engagement in preventative behaviors.

Effectiveness of an Educational Program on Awareness of Cancer Risk Factors, Symptoms, and Barriers to Medical Help-Seeking Among Adolescent Omani Students: an Interventional Study

Cancer is the second leading cause of death worldwide, with attributable mortality expected to continue increasing over time. High school students are often targeted to enhance awareness of cancer risk factors and symptoms and promote early medical help-seeking behaviors. This study aimed to evaluate the effectiveness of a cancer education program among Omani adolescents. A total of 12 public schools were randomly selected from three governorates and assigned to either the intervention or control group. Students attending grades 10 and 11 at the selected schools were targeted. The Cancer Awareness Measure tool was used to evaluate knowledge of cancer risk factors and symptoms, perceived barriers to seeking medical help, and anticipated time to consult a doctor for cancer warning symptoms at baseline (T0) and after 4 weeks (T1). After T0, the intervention group participated in a 1-h cancer education program involving a slideshow presentation and group discussion; they also received a leaflet and online access to program materials and videos. A total of 1716 students were enrolled in the study, including 886 (51.6%) assigned to the control group and 830 (48.4%) to the intervention group. Recognition of cancer risk factors (Z = 24.86; p ˂ 0.001) and cancer symptoms (Z = 24.91; p ˂ 0.001) significantly improved in the intervention group between T0 and T1, and compared to the control group at T1 (U = 33.28; p ˂ 0.001, and U = 34.55; p ˂ 0.001, respectively). In addition, anticipated time to help-seeking (Z = 20.15; p ˂ 0.001) and barriers to help-seeking (Z = 10.33; p < 0.001) decreased significantly between T0 and T1, and compared to the control group at T1 (U = 19.00; p ˂ 0.001, and U = 3.58; p < 0.001, respectively). The intervention effectively increased knowledge of cancer risk factors and symptoms and promoted early medical help-seeking behaviors among school-aged Omani adolescents. Integration of cancer education within high school curricula can aid cancer prevention and early intervention efforts. However, additional follow-up is required to confirm the long-term effectiveness of such programs.

An Inquiry into Cancer-Related Knowledge, Understanding, and Health-Seeking Behavior of Men Living in South Africa

In 2018, we conducted a survey among a convenience sample of men (n = 205) living in a resource-poor, semi-urban community in South Africa. We aimed to describe what they know about cancer by asking questions about cancer-related knowledge and understanding, and health-seeking behavior. We also investigated possible relationships between the variables. We used a researcher-administered questionnaire to collect the data and descriptive statistics and quantitative content analyses for the analysis. Chi-square was used to examine the relationships. The mean age of the sample was 35 years, and 49.8% (n = 102) attended 11 or 12 years of school. One-third (32.7%; n = 67) indicated they knew what cancer was, but only 28.8% (n = 59) gave an explanation: "very dangerous/a killer/worse than HIV" were the most common explanations. Only 24.9% (n = 51) were able to identify a possible warning sign, and "feeling very sick" was the most common. However, more than 60% considered six of the seven warning signs of cancer as serious. When suspecting they might have cancer, most (77%; n = 159) indicated they would tell the preferred person within 1 week, while 5.9% (n = 12) would tell "nobody." Although the majority (52.2%; n = 107) felt their partners and families motivated them to seek healthcare when sick, 28.3% (n = 58) needed permission to consult a professional. Educating the community about cancer in a culturally sensitive manner, irrespective of their educational level and perceived knowledge of cancer, could improve knowledge and understanding and lead to seeking healthcare timely.

Assessing Knowledge and Perceptions About Cancer Among American Indians of the Zuni Pueblo, NM

American Indians (AIs) in New Mexico have lower cancer screening rates compared to other populations and are more likely to be diagnosed with cancer at an advanced stage of the disease as reported by Li et al. (Archives of Internal Medicine 163(1):49-56, 2003). AIs also have the lowest 5-year cancer survival rates compared to any ethnic/racial group in the USA as reported by Clegg et al. (Arch Intern Med 162:1985-1993, 2002) and Edwards et al. (Cancer 97:1407-1427, 2005). Numerous barriers such as cultural beliefs, fear, fatalism, mistrust, stigma, and lack of culturally appropriate interventions could contribute to low cancer screening rates as reported by Daley et al. (J Health Dispar Res Pract 5(2), 2012); Filippi et al. (J Prim Care Community Health 4(3):160-166, 2013); James et al. (Prev Chronic Dis 10:E170, 2013); and Schumacher et al. (Cancer Causes Control 19(7):725-737, 2008). Trained Community Health Representatives (CHRs) from the Zuni Pueblo and native Zuni undergraduate students led six 1-h focus group sessions using a structured focus group guide with probes. The focus groups were conducted among 51 participants from different age groups (20-29 years, n = 19; 30-49 years, n = 17; and 50 years and older, n = 15) stratified by sex. Focus groups were conducted in both English and Shiwi (Zuni) languages. Sessions were audio recorded, and team members took notes. CHRs transcribed the notes and audio recordings, and created a codebook for qualitative data analysis. In the focus groups, participants provided Zuni-specific cultural context, opinion, and experience regarding (1) general knowledge about cancer, (2) cancer risk, (3) cancer risk reduction, (4) personal experiences with cancer, and (5) culturally competent delivery of cancer information and resources. Understanding the perceptions of cancer within the Zuni Pueblo is an essential component in the development of interventional/preventative measures and improvement of current care. Ultimately, this information will provide a basis for the next steps in culturally sensitive cancer care for the Zuni Pueblo.

Development and psychometric properties of a brief generic cancer knowledge scale for patients (BCKS-10)

Purpose

This study aims to introduce the development and psychometric properties of a brief generic cancer knowledge scale for patients (BCKS-10) that includes different elements of knowledge and skills (terminology, diagnosis, treatment, prevention, and numeracy). Although cancer knowledge is a central dimension of cancer literacy, most previous studies either investigated cancer knowledge among the general population, or among patients with a specific cancer diagnosis.

Methods

Qualitative interviews (n = 11) and a quantitative survey (n = 267) among peer support group leaders were conducted to further develop the BCKS-10 after literature screening. n = 500 patients with cancer were recruited across Germany between October 2020 and February 2021. Construct validity, item discrimination and reliability were tested.

Results

ANOVA revealed no significant differences of the knowledge score between various cancer sites, a significant positive association with education, and a negative association with migration background by trend supporting construct validity. In terms of item discrimination, the corrected item-total correlation of 8 out of 10 items were above the threshold of 0.3. Cronbach’s alpha of about 0.68 revealed an acceptable internal consistency as the tool is brief and consists of different dimensions.

Conclusion

Overall, the findings show that the BCKS-10 is a suitable tool to briefly assess cancer knowledge among patients independent of cancer site. However, further surveys have to be conducted to validate the psychometric properties and enhance the BCKS-10.

Development and validation of the Cancer Knowledge Scale for the general population: An item response theory approach

OBJECTIVE

To develop and validate a new measure of cancer knowledge for members of the general population who have never been diagnosed with cancer.

METHODS

Initially, 20 items were generated to measure cancer knowledge. After expert refinement and cognitive interviews, 11 items remained and were completed by 1,076 adults with no history of cancer. Responses were assessed using an item response theory (IRT) approach and differential item functioning.

RESULTS

Items were analyzed using a two-parameter logistic IRT model. Two items with tetrachoric correlation coefficients>0.8 and one item with a discrimination parameter>2.0 were excluded. The final eight items demonstrated a good range of discrimination (1.13 to 1.86) and difficulty (-1.11 to 0.85). No meaningful differential item functioning by participant attributes was detected for these eight items.

CONCLUSION

The Cancer Knowledge Scale appears to be a reliable and valid measure for the general population.

PRACTICE IMPLICATIONS

The eight-item scale could be used to assess the effects of psychoeducational programs, including those on cancer knowledge, for members of the general population with no cancer history.

The Evolution of Un Abrazo Para La Familia: Implications for Survivors of Cancer

Un Abrazo Para La Familia™ (Abrazo) is a 3-h modular preventive intervention designed for low-income caregivers who are co-survivors of cancer. Here we (1) consider the benefit to survivors of cancer, that is, the care recipients who participate in Abrazo; (2) summarize the literature specific to research outreach to low-income, underserved populations when they are faced with cancer; and (3) describe current steps being taken in Southern Arizona to reach these populations via Abrazo. Specific to considering the benefit to care recipients, we analyzed care recipient data derived from three existing cohorts of Abrazo participants. Analyses of the combined cohorts of these data demonstrate that Abrazo is effective with care recipients given statistically significant higher cancer knowledge and self-efficacy scores, pre- vs. post-intervention. We can now report benefit to care recipients who participate in Abrazo. This allows us, with confidence, to expand research recruitment efforts to include care recipients as part of the Abrazo intervention in our efforts to serve low-income, underserved populations when faced with cancer.

Reflections: a Daughter's Experience of Parental Cancer and the Beginnings of Un Abrazo Para La Familia™

The author describes her impetus and journey in developing Un Abrazo Para La Familia™ [Embracing the Family] (Abrazo), 3 hours of cancer information presented in an educational and modular format and designed for low-income informal caregivers who are co-survivors of cancer. A rehabilitation-informed preventive intervention, Abrazo reflects the importance of family, culture, and socioeconomic background in its approach.

The Effectiveness of Interventional Cancer Education Programs for School Students Aged 8-19 Years: a Systematic Review

The implementation of effective interventional cancer education programs in schools could help to reduce delays in diagnosis and improve cancer survival by increasing awareness of risk factors and symptoms among students. The aim of this review was to determine the effectiveness of interventional cancer education programs delivered to school students aged 8-19 years. Various databases were searched to identify controlled and uncontrolled studies published in English language articles between January 2000 and January 2020. Selected publications were then critically appraised using the Joanna Briggs Institute Critical Appraisal Checklist for Systematic Reviews. A total of 12 studies meeting these criteria were identified. Of these, eight were randomized, and five included control groups. All of the studies conducted the intervention over the course of 1, 3, or 4 days, and there was no follow-up phase in seven studies. Various modes and materials were used in the delivery of the interventions, including children's books and booklets, expert talks or presentations, videos, discussions, role-playing exercises, hands-on activities, group work, quizzes, and homework. There was some evidence to indicate that the interventions enhanced short-term knowledge, attitudes, self-efficacy, and behavioral intentions; however, there was less evidence regarding their long-term effectiveness, particularly in terms of help-seeking barriers. Interventional education programs are important to increase knowledge of cancer among school students aged 8-19 years. Decision-makers should consider including relevant topics within the educational curricula. Both healthcare providers and non-educational organizations should work together to support effective cancer interventional education programs for school students as part of their long-term cancer prevention efforts.

Public knowledge about oral cancer in Uganda: a free dental camp experience

Purpose–

The purpose of this paper is to assess the levels of awareness and knowledge about oral cancer, its causes and or risk factors among Ugandan patients seeking oral healthcare.

Design/methodology/approach–

This was a cross-sectional study on adult patients who attended a free dental camp. An assistant-administered questionnaire either in English or Luganda was provided to every even-numbered registered adult who consented to participate in the study. Information on demographics and known risk factors for oral cancer were captured. The two knowledge questions on oral cancers were scored by adding up all the correctly identified causes, non-causes and risk factors then scored out of the total. Data analysis was done by calculating proportions, Student’s’ t-tests and χ² tests with significant p-value set at 0.05.

Findings–

The results showed a low level of awareness/knowledge about oral cancer in studied population. In total, 60 percent and less than 50 percent of respondents identified smoking and alcohol use as risk factors for oral cancer, respectively. Majority of respondents (88.8 percent) would seek help from medical personnel if diagnosed with oral cancer. Screening for cancer was low despite awareness and knowledge that it improves the chances of successful treatment.

Research limitations/implications–

Emphasis on risk factors including alcohol use in public health messages, use of mass media, religious and community leaders to disseminate messages to the communities and further research were recommended.

Practical implications–

We need to emphasize the role of alcohol in oral cancer causation just as we do for tobacco consumption.

Originality/value–

No study has been conducted in Uganda on the level of awareness yet the incidence of the disease and use of high-risk products are rising.

Development of a Measurement Tool to Assess Students' Knowledge and Perceptions About Cancer (SKPaC)

Cancer literacy is currently one of the most important dimensions of cancer continuum. Objective assessment of cancer knowledge in populations remains a challenging field to public health entities. Different evaluation tools are currently available; still, some groups remain disregarded due to the absence of validated instruments. Cancer literacy in adolescents and young adults has been clearly overlooked being a subject that requires new tools to be properly studied. To address this topic, we developed a new instrument and field tested it in a classroom environment for internal reliability, construct, and face validity. "Students Knowledge and Perceptions about Cancer questionnaire" was designed in Portuguese language and adapted to the Portuguese context by a multidisciplinary team. The final version of the questionnaire includes 35 items organized in three sections, encompassing knowledge and perceptions about cancer and socio-biographic data. Cancer experts ensured content validity, while tailoring of contents was refined with high school teachers. Test and retest of the instrument showed a good reliability of the scale and construct validity. Also, the clarity of the questionnaire and suitability to proper evaluate cancer knowledge was consistent between test and retest. The Students' Knowledge and Perceptions About Cancer Questionnaire (SKPaC) showed to be a valid tool to assess adolescents' knowledge and perceptions about cancer that can be used in the educational context.

Subjective and Objective Cancer Screening Knowledge Among White- and Blue-Collar Chinese Midlife Adults

Cancer is the leading cause of death among Chinese, yet little is known about cancer knowledge among this population. The study described the subjective and objective cancer screening knowledge among white- versus blue-collar Chinese midlife adults. A convenient sample of white-collar adults age 40+ years was recruited from government and academic agencies; and blue-collar adults age 40+ years were recruited from manufactory companies in Taiwan. An eight-item cancer screening knowledge test (CSKT) was used to measure objective knowledge and one five-point Likert scale item for assessing subjective (perceived) cancer screening knowledge. A total of 208 white- and 533 blue-collar workers completed the survey during 2008-2011. Mean ages between groups were comparable (41.1 versus 46.3 years), as well as family cancer history (41.5 %). About 76 % of the white-collar and 43 % of the blue-collar adults had college education. The mean score of the CSKT was lower in the blue-collar versus white-collar workers, 5.4 (SD = 1.76) versus 6.1 (SD = 1.40), indicating on average, 68 versus 76 % of the participants answered the cancer knowledge correctly. The subjective knowledge levels were, however, higher among the blue-collar workers (mean rating of 3.22 versus 2.78). The CSKT showed a good mix of relatively easy and moderately difficult items in both groups. Study showed that overall cancer screening knowledge was low among Chinese midlife adults. Although blue-collar workers scored lower on CSKT, the perceived knowledge level was higher. Results also suggest attention to communicating cancer screening information among Chinese blue-collar midlife workers in particular.

Awareness of Risk Factors for Breast, Lung and Cervical Cancer in a UK Student Population

The objective of this study is to identify levels of risk awareness for breast, lung and cervical cancer, in a UK student population. A sample of male (N=62) and female (N=58) university students, mean age 21.62 years completed a questionnaire identifying which risk factors they knew for each cancer. Analysis of variance was used to compare differences in risk awareness across gender and cancer types. Risk factor awareness was highest for lung cancer (0.78), mid-range for breast cancer (0.61) and lowest for cervical cancer (0.47). Women had greater risk factor awareness (0.67) than males (0.57) across all three cancers. There is also significant belief in mythic risk factors such as stress (from 14 to 40% across the three cancers). Previous research has demonstrated that risk factor awareness increases with educational status, yet even in a university student population, in which the majority of females would have been offered the HPV vaccination, risk factor awareness for cancers is variable. More health education is needed particularly around the risk factors for cervical cancer.
