Ontology refers to researchers’ assumptions about the nature of the social world, for example, positivist researchers tend to assume that the social world operates in a predictable, law-like manner analogous to the physical world. Epistemology refers to researchers’ assumptions about how to gain knowledge about the social world, for example positivist researchers assume that one should measure social phenomena objectively. Methodology refers to the actual procedures used by researchers, for example positivist researchers frequently collect data by means of objective tests and questionnaires and analyse these using statistical techniques. The table summarises the ontological, epistemological and methodological characteristics of the three research paradigms. Extract 1 (positivist research) To determine which factors from a range of demographic, perinatal, psychosocial and hormonal factors were related to postpartum depression, a sample of 81 women between two weeks and six months postpartum was divided into a depressed group (n=22) and a nondepressed group (n=59) by means of the Beck Depression Inventory as the main measure and the Visual Analogue Scale as an additional measure. (Spangenberg & Pieters, 1991) Extract 2 (interpretive research) The aim of this investigation was to gain an understanding of the life-world of people with diabetes and to acquire insight into the demanding aspects of their lives. (Cleaver & Pallourios, 1994) Extract 3 (constructionist research) Groups of male ex-university students' discourse about drinking was examined to identify the interpretative repertoires that they used to construct real-seeming versions o
