Costley et al. (2010) suggest that the selected strategies for gathering information and data from the field ought to be methodologically logical, for all intents and purposes and morally attainable, and fit for giving the kind of data required by the researcher. This is vital since it ensures that the data collected by the researcher is evaluated for the extent of information needed and their depth. Nonetheless, in data collection, there is evidence that the expense of the strategy, the precision of the information and the effectiveness of the information that is gathered, (SOURCE).
To collect data, the researcher used a qualitative approach. This method seeks to obtain a response to the question being researched upon, (Aveyard, 2014). It has been noted that qualitative studies provide researchers with the perceptions and experiences of both nursing staff and dual diagnosis service users in minimising violent and aggressive behaviour, (Polit and Beck, 2014). Therefore, the aim and objective of the research are achieved by using the selected approach. From dual

Firstly, the study is reliant on the researchers’ skills as identified by undertaking observation and focus groups interviews (SOURCE). Another disadvantage identified is that data collections appear cumbersome and costly (SOURCE). This is because the process of data collection is deemed time-consuming compared to quantitative research. As such, it requires a lot of resource commitments namely the cost element and human resources hence the need for a smaller sample size (SOURCE). Furthermore, generalising in qualitative research is considered difficult. Generalising outcomes of the broad population is considered impossible due to the small sample size of participants (Silverman, 2013). Likewise, systematic comparisons are challenging to make as evidenced by the various feedback received from participants
