Correlation Of Uncertainty In Illness、health Belief And Colorectal Cancer Screening In Family Members Of Patients With Colorectal Cancer

ObjectiveTo investigate the current status of uncertainty in illness,health belief and CRC screening of family members of patients with CRC,and to explore the influence of uncertainty in illness and health belief on CRC screening.It will be useful to provide theoretical foundation for CRC screening and prevention.MethodsA cross-sectional study design was used.504 family members of patients with CRC in Wuhan tertiary hospital were recruited conveniently.The self-developed general condition questionnaire,Mishel Uncertainty in Illness Scale-Family,Colorectal Cancer Health Belief Scale were adopted.CRC screening included if family members had accepted the colonoscopy or not.SPSS 22.0 was processed for data analysis.The general information and scores of each scale were described by frequency,percentage and mean ± standard deviation.The analysis in scores of uncertainty in illness,health belief and CRC screening among the general information were used by t test,variance analysis and chi-square test.Multivariate binary Logistic regression analysis was used to determine the influencing factors of CRC screening.Results(1)The total score of uncertainty in illness was(83.43±12.36).The scores of the four dimensions were: uncertainty(38.09±5.46),complexity(20.40±3.20),unpredictability(12.84±1.40)and lack of information(12.10±2.30).(2)The total score of health belief was(117.90±12.34).The scores of the six dimensions were: perceived health motivation(24.68±4.33),perceived severity of CRC(22.10±4.30),perceived benefit of CRC screening(21.30±3.54),perceived obstacle of CRC screening(17.98±4.09),self-efficacy of CRC screening(17.34±2.79),perceived susceptibility of CRC(14.50±3.41).(3)There were 120 family members(23.81%)accepted the colonoscopy.(4)The results of one-factor analysis of variance showed that there were statistical significances of uncertainty in illness on education,residence and household income per capita(P<0.05).Family members with low education and household income per capita,living in rural area had high scores of uncertainty in illness.(5)The results of one-factor analysis of variance showed that there were statistical significances of health belief on education and household income per capita(P<0.05).Family members with high education and household income per capita had high scores of health belief.(6)The results of one-factor analysis of variance showed that there were statistical significances of CRC screening in age,education,marital status,residence and profession(P<0.05).(7)Pearson correlation showed that there was a negative correlation between uncertainty in illness and health belief(r=-0.822,P<0.01),CRC screening was negatively correlated with uncertainty in illness(r=-0.790,P<0.01),and positively correlated with health belief(r=0.715,P<0.01)(8)The results of logistic regression showed that education,lack of information,residence and perceived benefit of CRC screening were the main influencing factors of CRC screening(P<0.05).Conclusions(1)Family members of patients with CRC had a high degree of uncertain in illness,which were related to education,residence and household income per capita.(2)Family members of patients with CRC had medium level degree of health belief,which were related to education and household income per capita.(3)There was negative correlation between uncertainty in illness and health belief;CRC screening was negatively correlated with uncertainty in illness,and positively correlated with health belief.(4)The CRC screening participation rate was low.The results shows that education,lack of information,residence and perceived benefit of CRC screening were the main influencing factors of CRC screening.
