Major depression is a common illness, with a lifetime prevalence rate of 10-13% for men and 21-24% for women. The experience of having a serious illness such as major depression affects the individual's quality of life and requires significant adaptation in order to cope. The aim of this study was to explore sense of coherence and social support in patients treated for a first episode of major depression in a 1-year follow up. The study design was prospective and longitudinal. A total of 24 patients, aged 18 years or over, with a first episode of major depression were included. Semi-structured interviews and self-assessment questionnaires were used at baseline as well as in a 1-year follow up in order to measure the level of severity of the depression, social support, and sense of coherence. The result showed that 71% of the patients had recovered at follow up. The sense of coherence scores were low at baseline, although the patients who recovered increased their sense of coherence scores significantly. Another factor of importance for recovery was a significant increase in social support. Social support is an important cornerstone in the restoration of a person's sense of coherence. It can be used in interventions that include the patient's family or close social network in combination with support to assist the patient to view his/her situation as comprehensible, manageable, and meaningful, thereby promoting or improving health. Mental health nurses are in a key position to identify patients' strengths and weaknesses so that the support and interventions provided can be tailored to meet the needs of each patient.
