    An integrated model of HIV/AIDS testing behaviour in the construction industry
    (Taylor & Francis, 2014) Bowen, Paul Anthony; Govender, Rajen; Edwards, Peter J; Cattell, Keith
    The South African construction industry is one of the economic sectors most adversely affected by the HIV/ AIDS pandemic. Prevalence rates exceed those of most other sectors. Little is known about the antibody testing behaviour of construction workers, and the determinants thereof. A field-administered questionnaire survey, using an item catalogue based on similar surveys, gathered data from 512 site-based construction employees in the Western Cape, South Africa. An integrated hypothesized conceptual model of testing behaviour, derived from the literature, was proposed as a starting point for data analysis. This model comprising demographic factors, lifestyle risk and condom use, alcohol consumption, drug use, knowledge about HIV/AIDS, prejudice towards HIV+ persons, and attitudinal fear of being tested, was used to explain testing behaviour. Bivariate analysis, regression modelling, and structural equation modelling were then used to test the conceptual model. A revised model was proposed. The findings indicate that: (1) employment type, alcohol consumption, drug use, and HIV/AIDS knowledge are the terminal predictors of testing behaviour; (2) knowledge about the disease is determined by education level and ethnicity; (3) age, gender, ethnicity and education behave as significant predictors of alcohol consumption; (4) drug use is predicted by employment type, education and alcohol consumption (marginally); and (5) the interrelationship between knowledge, prejudice, and fear of being tested is nuanced and complex. In strategies for positively influencing employee testing behaviour, employers should first ensure that effective communication is established with workers in all employment categories. Interventions relating to alcohol consumption and drug use by employees need particular attention. Existing peer educator training, and awareness campaign media, should be particularly sensitive to ethnic and cultural values that are likely to influence HIV/AIDS testing behaviour.

    Validating survey measurement scales for AIDS-related knowledge and stigma among construction workers in South Africa
    (BioMed Central, 2016-01-23) Bowen, Paul; Govender, Rajen; Edwards, Peter
    Background: Construction workers in South Africa are regarded as a high-risk group in the context of HIV/AIDS. HIV testing is pivotal to controlling HIV transmission and providing palliative care and AIDS-related knowledge and stigma are key issues in addressing the likelihood of testing behaviour. In exploring these issues, various studies have employed an 11-item AIDS-related knowledge scale (Kalichman and Simbayi, AIDS Care 16:572-580, 2004) and a 9-item stigma scale (Kalichman et al., AIDS Behav 9:135-143, 2005), but little evidence exists confirming the psychometric properties of these scales. Methods: Using survey data from 512 construction workers in the Western Cape, South Africa, this research examines the validity and reliability of the two scales through exploratory and confirmatory factor analysis and internal consistency tests. Results: From confirmatory factor analysis, a revised 10-item knowledge scale was developed (χ2 /df ratio = 1.675, CFI = 0.982, RMSEA = 0.038, and Hoelter (95 %) =393). A revised 8-item stigma scale was also developed (χ2 /df ratio = 1.929, CFI = 0.974, RMSEA = 0.045, and Hoelter (95 %) = 380). Both revised scales demonstrated good model fit and all factor loadings were significant (p < 0.01). Reliability analysis demonstrated excellent to good internal consistency, with alpha values of 0.80 and 0.74, respectively. Both revised scales also demonstrated satisfactory convergent and divergent validity. Limitations of the original survey from which the data was obtained include the failure to properly account for respondent selection of language for completion of the survey, use of ethnicity as a proxy for identifying the native language of participants, the limited geographical area from which the survey data was collected, and the limitations associated with the convenience sample. A limitation of the validation study was the lack of available data for a more robust examination of reliability beyond internal consistency, such as test-retest reliability. Conclusions: The revised knowledge and stigma scales offered here hold considerable promise as measures of AIDS related knowledge and stigma among South African construction workers.
