“…In addition to being paradigmatically flexible [20], this approach enables flexible boundaries around what entails the case, is ideal for investigating phenomena on which little is known, and promotes a commitment to intense, contextually-minded, and the holistic study of a case. Given that the app functions and is influenced by young adults' contextually-laden day-to-day lives, case study was an ideal method for investigating the interactions between CTC and young adult end-users.…”

Background: Smartphone apps have emerged as a promising way to reach young adult smokers given their high smartphone ownership rates, and openness to receiving cessation support via digital technologies. While emerging evidence indicates that quit smoking apps are an effective way to reduce smoking among young adults, lacking is formative evaluative research that captures the perspectives of end-users. Objective: The objective of this study was to contribute insights toward understanding how young adults interact with the Crush the Crave (CTC app), and how this interaction shapes young adults' smoking cessation experiences and practices, with consideration for the influence of gender. Methods: Semi-structured interviews were conducted with 31 young adult CTC users. Guided by sociomateriality theory and an affordances approach, data were inductively analyzed to derive thematic findings in relation to the impacts of CTC on quit efforts, and to expose the underlying affordances (mechanisms) that lend to these outcomes. Findings were grouped according to the 4 design components of CTC: credibility, social support, task support and dialogue support. Results: The credibility component of CTC played an important role in harnessing the trust of young adults because it afforded them promise in relation to its potential effectiveness in assisting them with quitting smoking. Affordances of the social support component lent to various user practices and experiences that rendered this aspect as the weakest component in supporting quit efforts. While most functions situated in the task and dialogue support components were found to be helpful, there were a few affordances in CTC that resulted in negative experiences, notably weaning from smoking. Gender-related influences were also evident. For example, young men preferred to control and self-manage their quitting and, therefore, did not engage with functions that afforded journaling or reminding to stay on track. Women, by contrast were more likely to benefit from these affordances. Conclusion: An affordances approach is productive for gaining an in-depth understanding of how mobile apps interact with users to lend to particular outcomes. The study findings have implications for developing and improving apps for helping young adults quit smoking, as well as apps that target other health behaviours. Productive affordances may also serve as a beginning framework for leveraging apps for smoking cessation.

“…Case studies have also been criticised for lacking rigour (Jensen & Rodgers 2001in Luck, Usher & Jackson 2005. Luck et al (2001), however, advise researchers to address objectivity and rigour issues by planning the case study research and applying the usual requirements for rigour applicable to their chosen methods. Generalisation is also a limitation (Polit & Beck 2010), as the study reflects the findings applicable to one person in a specific context.…”

The purpose of the study was to demonstrate that breast cancer related lymphoedema can be managed by means of Complete Decompression Therapy and consequently improve quality of life. An instrumental case study design was used. The target population was all women with breast cancer related lymphoedema living in Tshwane, the context of the study. The patient with the most severe breast cancer related lymphoedema treated by the researcher is presented. Mixed methods were used to gather data. The expected 60% limb volume reduction could not be achieved after 4 weeks of induction therapy. After 8.5 weeks of treatment, the limb volume reduced from the initial 3841 mL to 1639 mL, a 57.2% reduction. Patient compliance to compression therapy was a challenge and led to relapse extending the induction phase of treatment. Despite the prolonged treatment, the limb volume reduction improved the patient’s quality of life. The study demonstrated and confirmed that despite a degree of noncompliance, breast cancer related lymphoedema can be managed with Complete Decongestive Therapy which, in turn, improves the quality of life of women living with breast cancer.OpsommingDie doelstelling van die studie was om te demonstreer dat borskanker-verwante limfedeem deur middel van Volledige Dekompressie Terapie beheer kan word wat gevolglik die pasiënt se lewenskwaliteit verbeter. ‘n Instrumentele gevallestudie-ontwerp is gevolg. Die populasie waaruit die geval gekies is, het uit alle vroue met borskanker-verwante limfedeem in Tshwane, die konteks van die studie, bestaan. Die pasiënt met die ergste limfedeem wat die navorser behandel het, word voorgedra. Gekombineerde metode is ingespan om data in te samel. Die verwagte 60% vermindering in die armedeem binne 4 weke van induksie behandeling is nie bereik nie. Na 8.5 weke van behandeling het die edeem van die oorspronklike 3841 mL tot 1639 mL verminder wat ‘n 57.2% reduksie verteenwoordig. Die pasiënt het nie die voorskrifte ten opsigte van dekompressie terapie noukeurig nagekom nie, wat terugvalling en ‘n verlengde induksie-fase tot gevolg gehad het. Die vermindering van die armedeem het die pasiënt se lewenskwaliteit nogtans positief beïnvloed. Die studie het aangetoon dat, ten spyte van pasiënt afvalligheid, dit moontlik was om borskanker-verwante limfedeem deur middel van Volledige Dekompressie Terapie te verminder en lewenskwaliteit te verbeter.

It is an appropriate design for exploring events, situations, programmes and activities (Hancock andAlgozzine 2006, Berg 2009).…”

Background Case study research is a valuable way to explore and describe nursing phenomena in their natural contexts. Multiple sources of evidence are critical in this approach. It is imperative that the strategies for selection, collection and analysis of cases are considered and articulated in the early stages of planning, to avoid having large datasets which cannot be harmonised. AimTo critically examine what is meant by 'multiple sources of evidence' and how they can be used in case study research. Two examples of case study research are used to illustrate the decisions the authors made during the selection, collection and analysis stages of the research. DiscussionThese decisions included what sources would be used, rationales for their use, and how the data would be collected and analysed. In addition, multiple sources of evidence can result in large amounts of data so the use of NVivo to manage the data is described.Conclusion Each source of evidence selected must have a clear purpose and relate to the study's objectives. Clarification of this during the early planning of any research is imperative.Implications for practice The authors hope that the examples provided to illustrate how multiple sources of evidence are used will guide researchers conducting case study research.
