Description

Qualitative research takes place in the real world, as opposed to the laboratory, and deals with how people give meaning to their own experiences. It involves research of behaviour in a natural setting, and is followed by an attempt to interpret the behaviour and the meanings that people have given to their experiences.

Qualitative research strategies include the use of observations, interviews and case studies, among others. These will often involve face‑to‑face interactions between researcher and participant where the researcher needs to be flexible and sensitive to the needs of the social context within which the data is obtained. The data is subsequently analysed and interpreted. Generally the aim of qualitative research is to allow themes, categories or theories to emerge from the data, rather than to focus narrowly on preconceived ideas or hypotheses.

Sampling methods used in qualitative research are significantly different to those used in quantitative research. Random sampling is not normally used, as generalization of findings to a large population is less important. Purposive sampling is preferred in qualitative research; participants are often selected for their salient features, which are closely tied to the research aim.

The number of participants used in qualitative studies is often small and may, in some cases, be limited to a single individual. Qualitative research normally deals with few participants since its great value lies in understanding the in‑depth experiences and feelings of individuals. Psychologists have learned much from the qualitative research that they currently employ and continue to develop, including the notion that it is possible, with considerable care, to offer a limited degree of generalization from their findings.

The qualitative approach needs to be transparent in the description of the methods that it uses since this adds to its credibility. Credibility improves when researchers are reflexive; they attempt to make readers of their research aware of their own potential researcher bias. In addition, it should be acknowledged that participants in the research may change their minds as the research proceeds. The methods used to produce data and the manner of analysis can and do influence research findings.

Particularly for those who are new to qualitative research, it is imperative to be able to tolerate a degree of uncertainty. Human behaviour is frequently complex; the meaning of similar experiences may be interpreted differently by individuals. For example, chronic injury may have a devastating effect upon elite athletes and their immediate family members since it may involve the end of a playing career and a substantial fall of income; but for others, the same injury may offer an opportunity to retire gracefully from the continual demands of their sport and to start a new career in a different area.

It is important for students to realize that qualitative and quantitative research complement each other. Each is suited to investigating different aspects of behaviour and should be used appropriately.
