A descriptive correlational study was conducted to investigate the relationship between perceived social support and mood of testicular cancer patients two to three months post-diagnosis. The conceptualization for the study was based on the cognitive-phenomenological theory of psychological stress (Lazarus and Folkman, 1984). A convenience sample of 30 young adult males with testicular cancer was interviewed. Data were collected using the Demographic Data Sheet, MOS Social Support Survey. Importance of Social Support Questionnaire, Profile of Mood States and two open-ended interview questions. Data indicated subjects felt well-supported, especially in areas that they thought were important. No significant relationship was found between perceived social support and mood in this sample. The findings suggest the need for the nurse's individualized assessment regarding the testicular cancer patient's number of close friends/relatives and the importance placed on different types of support.
