Text in English / Health Communication Campaigns are one of the strategies used in facing the challenges of the spread and effects of the HIV/AIDS epidemic, which is not only a health issue but also has sociocultural implications and consequences. Although there are some models and research tools available to guide the planning, designing, implementing, monitoring and evaluation of health communication campaigns, the premise of the study was on two assumptions. First, most available models that guide the planning and execution of HIV/AIDS communication campaigns do not sufficiently highlight sociocultural variables; and second, since most available models do not sufficiently emphasise sociocultural variables, the design of the instruments for the assessment of the campaigns are not sufficiently geared towards identifying and assessing sociocultural variables of the campaigns. In light of these assumptions, the study was undertaken for three reasons. Firstly, to construct a sociocultural health communication campaign conceptual model that incorporates and highlights sociocultural variables to guide the planning and implementation of health communication campaigns; particularly HIV/AIDS communication campaigns. Secondly to develop an assessment instrument for assessing the presence or absence of sociocultural variables in the planning and implementation of health communication campaigns. Thirdly to test the theoretical sociocultural assessment instrument developed in the study in an HIV/AIDS communication campaign of the Ekurhuleni Metropolitan Municipality’s HIV/AIDS Unit. The results indicated that the instrument is a functional sociocultural assessment tool that can be used to determine three main aspects. Firstly, whether or not and at what level there is/or was active involvement and participation of the target audience in the communication campaigns process. Secondly, whether or not and at what level in the planning and execution of a campaign, the sociocultural context was taken into consideration and the relevant elements of such context incorporated in the campaign process. Thirdly, whether or not and at what level relevant theories/models underpinned the whole process of the health communication campaigns in the planning, designing, implementation, monitoring and evaluation stages. The sociocultural assessment instrument, therefore, is not meant for assessing the effectiveness of health communication campaigns per se. It is rather meant for use to ascertain the presence or absence of those three aspects on the assumption that if they are taking care of in the planning and implementation of such campaigns, the probability is that the campaigns would be more socioculturally appropriate. The implications of this study are that for health communication campaigns to be socioculturally appropriate, they display continuous community interactivity and participative (ensuring mutual relationship between campaign planners and target audience) in their planning, implementation and evaluation/assessment; making the whole campaign process strategic and integrative – their management should be strategic, implementation creative and monitoring and evaluation continuous. / Communication Science / D.
