No full textThe testretest reliability of the Opiate Treatment Index in nyaope users in Johannesburg
No full textBackground: Epidemiological studies suggest that nyaope, a heroin-based drug, is widely used in South Africa. Yet few reliable research tools are available to assess treatment outcomes of users. The Opiate Treatment Index (OTI), a tool developed in Australia, could potentially facilitate research on context-specific South African treatment outcomes. However, we know little of its test-retest reliability.
Aim: This study aimed to assess the test-retest reliability of the OTI among a sample of nyaope
users in Johannesburg.
Setting: This study was conducted across three substance use treatment facilities in Johannesburg.
Methods: The OTI was administered to 53 nyaope users at baseline and one week later. To determine the test-retest reliability of the OTI, the intra-class correlation coefficients (ICC) and the Brennan–Prediger coefficients of the two interviews were calculated.
Results: The ICC of the Q-scores from the data sets along with the Brennan–Prediger coefficient for the substance use domain were calculated. The ICC for nyaope was 0.38. Brennan–Prediger coefficients were as follows: alcohol – 0.96, crack-cocaine – 0.89, cannabis – 0.92, methaqualone – 0.85 and crystal methamphetamine – 0.89.
Conclusion: A significant positive finding was the excellent test-retest reliability of the
injecting and sexual behaviour domains and moderate reliability of the criminality, general health and social functioning domains.
Contribution: The results of this study provide insight into the reliability of this tool and for its use in future studies in the South African context
The Care-Climate Nexus - A Conceptual Framework
No full textAs is widely acknowledged and evidenced, climate change threatens food security and sovereignty; water availability, accessibility and quality; health and livelihoods. Where women bear the primary responsibility of unpaid care work such as food provision, water collection, and care for the young, sick and elderly, climate change disproportionately disadvantages them. This applies to the work of care and, more broadly, to social reproduction. Climate change thus contributes to an ongoing crisis of care, exacerbating the injustices associated with women carrying a disproportionate share of unpaid care. As such, fostering a value for care could be a means through which social and environmental inequalities are equally addressed in an ecological transition. This paper expands on the conceptual linkages of a care-climate nexus, with the aim of supporting climate policy.International Development Research Cente (IDRC)SM202
