Structured and Unstructured Interviews: The interview technique involves orally asking questions and recording the answers. Interviews allow researchers to interact with participants and to explore psychologically interesting questions thoroughly. However, interviews take more time than other methods. Successful interviewing requires preparation and practice. If the questions are created in advance and the same questions are asked of each participant, the interviews are structured interviews. If the questions vary as a result of the interviewee’s responses, the interviews are unstructured interviews.
Example of Structured Inteview:
Unusual groups are a fruitful source for interview research. Campbell and Jones (2002) interviewed 10 world-class male wheelchair basketball players. The interviews focused on the sources of stress (both general and competition-related) experienced by these athletes. The interviews began with an introduction that set the context: the athletes’ experiences in their sport. The interview then moved to questions designed to help the athletes recall their wheelchair basketball experiences. Questions about both general and competition–related stress followed. The interview ended with questions about the interview itself. Interviews lasted as long as 150 minutes. All were tape recorded and transcribed. Each interviewee later verified the transcript for accuracy. The transcripts were analyzed with a technique called inductive content analysis. In this type of analysis, researchers independently read raw data transcripts searching for uniformities which are grouped into emergent themes. In the Campbell and Jones study, seven steps were used in data analysis:
Example of Unstructured Interview:
Johnson (1998) conducted unstructured interviews with 10 psychiatric patients (5 males and 5 females) who had been restrained for therapeutic reasons. (Therapeutic restraint is belting a patient to a bed to prevent self-injury.) Johnson began each interview by asking patients to recall the experience of restraint. After that opening question, she allowed the patients to speak their minds. Following the interviews, verbatim transcripts were examined for emerging themes. Two specific themes, power and powerlessness, were selected for further analysis. Patients under restraint did not feel safe and protected, nor did they see being restrained as a form of therapy. Instead, they saw restraint as the consequence of rule breaking or disobedience.
Focus groups are a kind of small group interview. Typically, researchers recruit participants, convene a meeting, and conduct structured or unstructured interviews with the whole group. Outside of colleges and universities, marketers and manufacturers often use focus group interviews to test consumer reactions to products and advertisements. Focus groups can also be considered collaborative research because the groups often develop a group identity and the members provide information not easily obtained from single-person interviews. Two differences between focus groups and other interviews are the number of interviewees and the social nature of the setting.
