This was a qualitative study that used a grounded theory approach. This approach can help researchers to investigate basic social and psychological processes within a social context (
13,
14). In this type of research, sampling is continued until the new code related to the phenomenon under the study is not found (
14,
15).
The key participants in the study were eight adolescents (three boys and five girls), aged 14 - 18 years, who had attempted suicide with medication and had been referred to two hospitals affiliated with Shiraz University of Medical Sciences. All of their fathers were addicted to drugs or alcohol. The emergency ward physicians confirmed that these adolescents had attempted suicide.
First, the interviewer (nurse) visited the adolescents in the ward and tried to elicit their trust so that they might participate in the study. After they agreed to participate, they were interviewed between 72 - 96 hours after being discharged. The times for the interviews were based on the patient’s medical status, availability, and preference. Exclusion criteria included the participant’s inability to share their experiences, whether due to lack of motivation, severe mental disease such as acute psychosis, or major depression.
Purposeful sampling was used because most people who have attempted suicide in the city of Shiraz are referred to these hospitals, and researchers try to provide maximum variation when sampling, including gender, culture, and socioeconomic status.
As data analysis progressed, some codes were applied to the interactions of adolescents with healthy parents, and the medical team continued theoretical sampling until the saturation level. Therefore, to elicit more comprehensive data collection during the theoretical sampling, one nurse, one psychologist, one psychiatrist, and two healthy adolescent mothers with no history of mental illness participated in the study. Theoretical sampling was continued until the new code related to the phenomenon under the study was not found.
At the beginning of each interview, the interviewer introduced himself to the participants and explained the purpose of the study and interviews. The interviews were semi-structured and started with a general question (“Please describe a day in your life.”). Based on the participants’ responses, the interviewer asked follow-up questions. Depending on the participants’ roles, other questions were asked, such as “Can you talk about addiction of your spouse?”
At the end of each interview, the interviewer asked the participants to talk about any important things that had not been mentioned during the interview. The interview sessions were held in a quiet place, and the participants were assured of privacy. The interviews were conducted from September 2013 to June 2014, and their mean duration was 70 minutes. The data were collected and analyzed simultaneously.
To facilitate data analysis, each interview was digitally recorded and transcribed into MAXQDA 10 Software. For statistical analysis, Strauss and Corbin’s (1998) approach, the constant comparative method, was used (
14). For open coding, the data were broken down into parts and basic concepts were extracted. Similar codes were grouped during the continual comparison process and inserted into a category that was determined by the properties of each of its concepts. Then the categories were extended and connected to sub-categories, in a process called axial coding. At this stage, the researchers used selective coding to refine the codes and integrate theory.
The researchers used the four criteria proposed by Lincoln and Guba credibility, dependability, confirmability, and transferability to increase the accuracy of the findings (
15). The credibility of the data was increased by the researchers’ prolonged involvement in the process of collecting and analyzing data from two hospitals and writing memos. They also confirmed the accuracy of that data analysis with three experts in qualitative research and checked the primary codes with some participants. The maximum sampling variation increased the data dependability and confirmability. Finally, data transferability was increased by the researchers providing a clear path, with sufficient detail, to how they arrived at their findings.
The ethics committee of Shiraz University of Medical Sciences approved the study (CT-92-6746). All the participants, and also the parents of adolescents under 15 years of age, signed the informed consent forms that were provided in accordance with the Helsinki Declaration.
