Predicting Behavioral Intentions Related to Cervical Cancer Screening Using a Three-Level Model for the TPB and SCT in Nanjing, China

Determinants of Low-Income Women's Participation in Self-Collected Samples for Cervical Cancer Detection: Application of the Theory of Planned Behavior

BACKGROUND

Low-income women (LIW) are underrepresented in physician-provided cervical cancer screening. Providing women with an option for Human Papillomavirus (HPV) self-sampling would increase cervical cancer screening. However, little is known about LIW's attitude towards self-sampling for cervical cancer. We determined the associations between the Theory of Planned Behavior (TPB) constructs and LIW intention for participation in the HPV self-sampling.

METHODS

A 44-item survey was administered among women receiving food from a food pantry in central Texas. Independent variables included TPB constructs (i.e., attitudes, subjective norms, and perceived control). The outcome variables were intentions and preference for self-sampling. Both variables were measured on a 5-point scale. Hierarchical linear regression models were used to analyze the data.

RESULTS

A sample of 241 participants (age 50.13 ± 9.60 years) comprising non-Hispanic White (40%), Black/African American (27%), and Hispanic (30%) participated in the study. The participants were current with a pap test (54.8%) and preferred self-sampling (42%). The participant's attitudes and subjective norms were significantly associated with their intention for self-sampling, accounting for 38.7% of the variance (p < .001). Women who were overdue for pap testing versus current with pap testing had increased odds of preferring self-sampling (OR = 1.72, 95% CI: 1.27, 6.04).

CONCLUSIONS

The key predictors for LIW's intention for self-sampling included attitudes and subjective norms. Future research should use the TPB as a framework to examine whether intention predicts self-sampling behavior among LIW.

Predictive power of PEN-3 cultural model in cervical cancer screening among women: a cross- sectional study in South of Iran

BACKGROUND

Cervical cancer (CC) can be prevented through early detection facilitated by screening as well as an early diagnosis and effective treatment of the precancerous lesions. The present research aimed to determine the predictors of cervical cancer screening (CCS) based on the PEN-3 model constructs.

METHODS

A cross-sectional study was conducted between September 2021- March 2022 with 840 women aged 15-49 in the city of Bandar Abbas, in the south of Iran, using a cluster sampling. The participants completed a valid and reliable self-administered questionnaire in person. The questionnaire included demographic characteristics, knowledge toward CC and the constructs of the PEN-3 model toward CCS. A multivariable logistic regression was used to determine the relationship and predictive power of model constructs with behavior as an outcome variable. The data were statistically analyzed in STATA14.2. The p-value < 0.05 was considered statistically significant.

RESULTS

A total of 810 questionnaires were analyzed (with a return of 95.63%). The mean and standard deviation of the participants' age was 30.97 ± 5.80 years. Pearson correlation coefficient analysis of all constructs and CCS behavior was statistically significant (P-value < 0.05). The multivariable logistic regression analytic results were enablers toward CCS (coefficient: 0.275) and Nurturers toward CCS (coefficient: 0.182), perceptions toward CCS (coefficient: 0.077) and knowledge toward CC (coefficient: 0.048, marginal significant) were predictors of CCS behavior. For the internal validity of the designed prediction model, a sample of 1000 was selected using the bootstrap sample replacement method which demonstrated the accuracy of the model PEN-3 is about 75% in predicting CCS behavior.

CONCLUSIONS

The results of the present research showed that personal factors such as perceptions and interpersonal factors such as enablers and nurturers toward CCS can predict CCS behavior. Therefore, in order to increase the acceptance of CCS in women, a set of intrapersonal and interpersonal factors should be taken into account.

Predictors of cancer screening behavior of the working population in China based on the information-motivation-behavioral skills model

Background

The cancer screening rate in the working population is very low in China. Information-motivation-behavioral skills (IMB) model has been applied to elucidate screening behavior for various chronic diseases but has not been investigated in analyzing cancer screening behavior. This study aimed to examine factors influencing cancer screening behavior and their linkages based on the IMB model.

Methods

A cross-sectional study was conducted in Shanghai, China from August to October 2021. Data were obtained through an anonymous questionnaire. Predictive relationships between variables in the IMB model and cancer screening behavior were evaluated. Structural equation modeling (SEM) was constructed to demonstrate the utility of the IMB model.

Results

Among the 556 participants included in the analysis, 34.4% of participants had ever done a cancer screening. The construct validation analysis supported that the measure items included were acceptable. SEM found that knowledge of cancer warning signs and symptoms (β = 0.563, p < 0.001) and cancer screening behavioral skills (β = 0.264, p = 0.003) were related to participation in cancer screening, whereas cancer screening motivation was not directly influenced the participation in cancer screening (β = - 0.075, p = 0.372).

Conclusion

The cancer screening rate was found to be lower than expected in the working population. The IMB model could be used to make decisions in implementing behavioral interventions to participate in cancer screening among the Chinese working population. Enhancing the knowledge of cancer warning signs and symptoms and strengthening behavioral skills should be focused on to improve participation in cancer screening.

Survey on determinants of intention to reduce nasopharyngeal cancer risk: an application of the theory of planned behavior

Background

To have better prognostic outcomes and minimize deaths due to nasopharyngeal cancer, it is vital to understand factors that motivate the public to undertake cancer preventive measures. The study investigated determinants of intention to adopt measures to reduce nasopharyngeal cancer risk using the Theory of Planned Behavior.

Method

A cross-sectional survey was conducted on Malaysians (n = 515) using a questionnaire on attitudes, subjective norm, perceived behavioral control, knowledge of nasopharyngeal cancer, past nasopharyngeal cancer preventive behavior, and intention to adopt preventive measures. The attitudes construct encompassed perceptions of susceptibility, severity, benefits and barriers. Hierarchical regression of mediation effect under structural equation model approach was used to test the theory. The model was re-estimated using the two-stage least square approach by instrumental approach. Next the Maximum Likelihood Estimation-Structural Equation Modeling was conducted to gauge the instrumentation and check the robustness of the model’s simultaneity.

Results

The respondents had moderate knowledge of nasopharyngeal cancer, and reported high levels of perceived risk, perceived severity and perceived behavioral control. The respondents were under little social pressure (subjective norm) to perform nasopharyngeal cancer preventive actions, marginally believed in the benefits of medical tests and reported few barriers. The Partial Least Squares-Structural Equation Modeling results show that the relationship between intention and four independent variables were significant (perceived behavioral control, perceived risk, perceived severity, marital status) at p < .05. Tests of Two-stage Least Square Approach and Maximum Likelihood Estimation-Structural Equation Modeling confirm the four key factors in determining the intention to reduce nasopharyngeal cancer risk. The variance explained by these factors is 33.01 and 32.73% using Two-stage Least Square Approach and Maximum Likelihood Estimation-Structural Equation Modeling respectively. Intention to undertake nasopharyngeal cancer risk-reducing behavior has no significant relationship with subjective norm, attitudes (perceived benefits and barriers to screening), knowledge of nasopharyngeal cancer and past behavior in enacting nasopharyngeal cancer preventive measures. The only demographic variable that affects intention is marital status. Gender, age, race, religion, education level, and income are not significantly associated with intention.

Conclusions

In contexts where knowledge of nasopharyngeal cancer is moderate, the factors associated with the intention to reduce risk are perceived risk and severity, perceived behavioral control, and marital status.

Correlates of cervical cancer screening participation, intention and self-efficacy among Muslim women in southern Ghana

Background

The World Health Organisation’s efforts to eliminate cervical cancer by 2030 with a target of 70% screening coverage using a high-performance test demand that women increase participation in screening. Factors that impact uptake of screening must therefore be identified and bottlenecks addressed, especially in lower- and middle-income countries where cervical cancer incidence remains high. This study investigated Muslim women, participation in, intention to engage in and self-efficacy about cervical cancer screening.

Methods

An analytical cross-sectional study was conducted among Muslim women aged 18 years and above in the Cape Coast Metropolis of Ghana using an interviewer-administered questionnaire. Data were analysed using appropriate descriptive statistics, Chi-square test, point biserial correlation and binary logistic regression analysis.

Results

The mean age of participants was approximately 31 years (M = 30.9, SD = 10.4). Out of the 431 women, 21 (4.9%) had ever participated in cervical cancer screening. Participants demonstrated very low knowledge about cervical cancer and screening, with a mean knowledge score of 3.68 out of 15. Knowledge about cervical cancer was associated with increased odds of participating in cervical cancer screening (aOR = 1.32, 95%CI 1.11, 1.56). Concerns about similarity with health provider in terms of gender and faith was associated with decreased odds of cervical cancer screening self-efficacy (aOR = 0.81, 95% CI 0.67). Islamic modesty (aOR = 0.88, 95%CI 0.81, 0.96) was associated with decreased self-efficacy about seeking cervical cancer screening, whereas attitude (aOR = 1.32, 95%CI 1.14, 1.53) was significantly associated with increased self-efficacy about seeking cervical cancer screening. Again, Islamic modesty (aOR = 0.88, 95%CI 0.80, 0.97) was associated with decreased intention to participate in screening, whereas attitude (aOR = 1.42, 95%CI 1.20, 1.68) was associated with increased intention to participate in screening.

Conclusions

There are gaps in knowledge of cervical cancer among Muslim women in this study as less than 5% had participated in screening. A positive attitude was found to influence intention to screen and actual participation in screening programmes. Islamic modesty and commitment to the Islamic faith decreased intention and self-efficacy regarding screening. Therefore, comprehensive and appropriate socio-cultural and religion-specific interventions aimed at addressing the barriers to screening are important in improving uptake among Muslim women.

Predicting Rural Women's Breast Cancer Screening Intention in China: A PLS-SEM Approach Based on the Theory of Planned Behavior

Background

It was reported that the incidence of breast cancer (BC) was the highest among cancers worldwide. The breast cancer screening (BCS) program is regarded as an effective preventive measure. However, rural women's willingness to participate in the BCS program is relatively low. To provide measures to prevent BC, it is necessary for the government to identify the influencing factors of rural women's BCS intention.

Methods

A cross-sectional study was conducted among 3,011 rural women by a convenience sampling method through face-to-face interviews on a self-designed questionnaire based on the theory of planned behavior (TPB). The partial least square structural equation model (PLS-SEM) was conducted to determine the predictors of BCS intention, and a multi-group analysis (MGA) of age was performed to identify if there were differences in all hypotheses between different age groups.

Results

There were still rural women who have not been screened for BC in five years (41.7%). The research model of rural women's intention to accept this prevention against BC was rational. All of the hypotheses are supported. Especially, subjective norm (SN) (β = 0.345, p &lt; 0.001) is found to be the strongest predictor followed by the perceived behavioral control 1 (PBC 1) (personal factors, including distance, transportation, busyness, etc.) (β = 0.165, p &lt; 0.001), attitude (β = 0.152, p &lt; 0.001), past behavior (PB) (β = 0.150, p &lt; 0.001), knowledge (β = 0.121, p &lt; 0.001), and perceived behavioral control 2 (PBC 2) (pain and cultural-social factors including embarrassment from a physician, etc.) (β = 0.042, p &lt; 0.05). The advocacy and education (A&amp;E), medical level and service attitude (ML&amp;SA) of township health centers and village clinics can affect behavior intention (BI) via attitude, SN, and PBC. The results of MGA of age indicate that there are significant differences among rural women of different ages regarding the relationship between A&amp;E and PBC 2 (p &lt; 0.01) and the effect of PB on BI (p &lt; 0.001).

Conclusion

The TPB with the addition of PB, knowledge, ML&amp;SA, and A&amp;E can provide the theoretical basis for the policy intervention that aims to enhance the rural women's BCS willingness. MGA of age is conducive to promoting the implementation of the BCS policy. The findings are of great significance to improve rural women's health levels.

A Critique of the Theory of Planned Behavior in the Cancer Screening Domain

The theory of planned behavior (TPB) has been widely used to guide research in cancer screening-related behavior, but no critique of the TPB's application in this domain has been published. We used Fawcett and DeSanto-Madeya's 2013 framework to analyze and evaluate the theory. The theory was developed on the basis of antecedent knowledge regarding human behavior, and its concepts and propositions are comprehensively delineated. The TPB shows adequate internal consistency and impressive social and theoretical significance. Methodologically sound studies are called for to further test some theory propositions and to evaluate its pragmatic adequacy for promoting cancer screening in nursing practice.

Turkish and Moroccan Dutch women’s views of using a self-sampling kit for human papillomavirus testing as a tool for cervical cancer screening: What are the barriers and the motivators?

Objective:

This study explores barriers and motivators to use self-sampling kits for human papillomavirus testing for cervical cancer screening as perceived by Dutch women of Turkish and Moroccan origin living in the Netherlands.

Methods:

A total of 11 in-depth semi-structured interviews were conducted and structured according to the theory of planned behavior.

Results:

Findings suggest that self-sampling may lift important barriers hampering traditional cervical cancer screening, such as those related to shame and chastity. However, self-sampling raises its own barriers too. Most importantly, some women fear that self-sampling may harm virginity. Some women also do not feel confident about their ability to properly use the self-sampling kit, but fears about the inability to properly use it often fade away upon having seen the self-sampling kit. Moreover, results show that knowledge about cervical cancer and its origin is limited, which may undermine women’s willingness to participate in a screening program.

Conclusions:

These results suggest that communication strategies to encourage using self-sampling kits among women of Turkish and Moroccan origin could benefit from culturally sensitive approaches, for example, by placing emphasis on issues such as virginity and chastity. Consistent with a recent advice of the Health Council of the Netherlands, the kit could furthermore be sent to eligible women as a standard procedure, rather than upon request. This could reduce hassle and doubts about women’s ability to use the self-sampling kit. Finally, educating women about the importance of screening to prevent cervical cancer is needed to foster informed decision-making.

Predictors of uptake of cervical cancer screening among women in Urban Tanzania: community-based cross-sectional study

OBJECTIVES

The proportion of women screened for cervical cancer in Tanzania remains small at 6-21%. Even though some studies have been conducted to address barriers, the screening uptake remains low, which denotes the presence of unidentified barriers. The main objective of this study is to assess the predictors in the uptake of cervical cancer screening (CCS) among women in Tanzania.

METHODS

This is a community-based cross-sectional study conducted to obtain quantitative data through validated questionnaires to assess predictors of CCS.

RESULTS

1013 (91.8%) of the respondents had not been screened for cervical cancer. Three predictors of CCS were identified in this study; screening intention, health beliefs, and knowledge level. 600 (54.4%) of respondents had no screening intention. 552 (50%) had negative health beliefs, and 585 (53%) had inadequate knowledge of cervical cancer and CCS. Respondents who had no intention to screen were 0.482 (AOR) times less likely to uptake CCS (P = 0.002; 95% CI: 0.305, 0.761).

CONCLUSIONS

The ongoing community-awareness raising campaigns should be coupled with community knowledge-raising campaign, and there should be an establishing of peer-supporting screening programs in communities.
