“…Then, one of the limitations of our study is that there is no independent gold standard for determining “true negative”. A study conducted by Muhlbacher ( Xu et al., 2020 ) et al. evaluated the performance of the Elecsys ® HIV Duo assay in five international centres and compared with other available 4th-generation tests.…”

“…Although the rate of HIV infection has decreased significantly compared with the early years, the current situation is still not optimistic. According to the World Health Organization, 37.7 million people were infected with HIV in 2020 worldwide; the number of deaths from AIDS topped the list of notifiable infectious diseases in China ( Xu et al., 2020 ). A total of 1,045 million living HIV/AIDS patients were reported in China by October 31, 2020.…”

BackgroundHIV/AIDS continues to be a serious health concern of morbidity and mortality globally, and novel HIV testing is still an important component of diagnosing HIV earlier and reducing the spread of HIV. The Elecsys® HIV Duo assay is a 4th generation assay that can detect both HIV-1 p24 antigen (Ag) and HIV-1/2 antibody (Ab) in parallel and show the subresults for the Ab and Ab units.ObjectivesTo evaluate the clinical performance of the Elecsys® HIV Duo assay on the new cobas E 801 analyzer using a large number of clinical samples from a population in southwest China.MethodsWe collected testing results and information from all patients in a large general hospital. All eligible clinical specimens were first analyzed using the Elecsys® HIV Duo assay. The test results are given either as reactive or nonreactive as well as in the form of a cutoff index (COI). All initially reactive specimens were retested in duplicate with a 3rd-generation kit. Supplementary tests were divided into Ab confirmation tests and HIV-1 nucleic acid tests. GraphPad Prism and Python were used for plotting, and SPSS 21.0 software was used for statistical analysis.ResultsA total of 186391 specimens were received, and 436 patients were confirmed to be positive for HIV. Among the 86 cases with contact history available, there were more males than females, and heterosexual transmission was the most common route of HIV infection. The Elecsys® HIV Duo assay displayed 99.94%, 99.93% and 99.98% specificity for inpatient, outpatient and physical examination patients, respectively. The median COI ratios of the false-positive group were significantly lower than those of the true-positive group.ConclusionsThe Elecsys® HIV Duo test (Cobase801 analyzer) differentiates the detection of HIV-1 p24 Ag and HIV-1/2 Ab with high specificity and facilitates the diagnosis of patients with early HIV infection. Therefore, the Elecsys®HIV Duo test is used for differentiation of antigen and antibody reactivity, making it suitable for routine clinical diagnosis.

“…Gholami and Schwarzer [ 11 ] have provided HAPA questionnaires to measure the social cognitive constructs of the HAPA model for a variety of health behaviours. Alternative versions of these questionnaires have subsequently been constructed and validated for specific health behaviours in specific groups, such as physical activity among schizophrenia patients [ 12 ], physical activity among diabetic patients [ 13 , 14 ], treatment adherence among haemodialysis patients [ 15 ] and condom use among high school children [ 16 ]. A variety of validation methods have been used in these studies; all of them used factor analysis to identify latent variables to represent the social cognitive constructs and Cronbach alphas to measure reliability.…”

“…A variety of validation methods have been used in these studies; all of them used factor analysis to identify latent variables to represent the social cognitive constructs and Cronbach alphas to measure reliability. Additionally, some researchers performed structural equation modelling using confirmatory fit analysis and path analysis to confirm the model [ 13 , 16 ]. While the type of validation analysis varied, all the researchers concluded that the questionnaires could be used successfully in HAPA-based interventions.…”

Objective The Health Action Process Approach (HAPA) describes social cognitive constructs related to behaviour change. A validated questionnaire is needed to measure these constructs in paediatric dentistry. The aim of this study was to improve an existing HAPA-based questionnaire for parents regarding brushing their children’s teeth and to assess its validity and reliability in a population of parents of high caries risk children. Methods Parents of high caries risk children of 3–10 years filled out the adjusted HAPA-based questionnaire. Mokken scale analysis, graded response model analyses, factor analyses and reliability analyses were performed according to the protocol of Dima. Discriminant validity was assessed by comparing the mean scores of the HAPA constructs between two groups of participants, based on different levels of caries experience, brushing frequency and education level of the mother. Results The Mokken scale analysis and factor analyses indicated a multidimensional eight factor scale. The graded response model did not fit our data. The subscale action control could be identified as a two-factor subscale. Reliability indices from the Dima protocol varied, for instance Cronbach alpha ranged from 0.73 to 0.96. The constructs coping self-efficacy, action planning and action control discriminated between brushing frequencies. Conclusions The adjusted HAPA-based questionnaire is an improved, valid and reliable instrument that could be used to evaluate HAPA-based interventions to improve children’s oral health.

“…Behavioral intention is one of the most powerful predictors of various actual behaviors 19 . Many studies on HAPA have focused on the preintentional phase, including condom use among senior high school students, condom use with various types of female sex partners among male individuals who inject drugs in China, and the behavioral intention of COVID-19 vaccination 18,20,21 . However, there are few studies on the behavioral intention of condom use during sexual intercourse with regular female partners among MSM.…”

Background Given the rapid rise in HIV infection among men who have sex with men (MSM) in China, they may be a potential bridge for HIV transmission to the general female population, and increasing condom use is an important protective measure. This study aimed to explore factors that influence the intention of condom use during sexual intercourse with regular female partners among MSM in Western China, based on the Health Action Process Approach model. Methods This study used a baseline sample from a cohort study of the National Science and Technology Major Project. A nonprobability sampling method was adopted to recruit MSM from western China. Information on sociodemographic characteristics, HIV-related characteristics, sexual behavior, and constructs of the Health Action Process Approach model was collected through structured questionnaires, and the data were analyzed using a structural equation model. Results Among 232 participants, 62.9% (146 of 232) intended to use condoms every time they had sex with their regular female partners during the following 3 months. The results of the structural equation model showed that self-efficacy had the greatest influence on behavioral intention (β = 0.398, P < 0.001), followed by negative outcome expectancy (β = −0.303, P < 0.05). In addition, risk perception (β = 0.206, P < 0.05) and positive outcome expectancy (β = 0.270, P < 0.01) had indirect effects on intention, whereas self-efficacy played a mediating role in these indirect influencing factors. Conclusions Risk perception, outcome expectancy, and self-efficacy are predictors of condom use intention, with self-efficacy in particular serving as a significant medium for future interventions. These findings could provide a reference for future targeted interventions to reduce the likelihood of HIV transmission from MSM to the female population.
