Spirituality plays an important role during old age, but reveals itself as a confounding mental health concept, which needs to be defined when providing spiritual care. The purpose of this study was to explore factors promoting Iranian older adults' spirituality. In a qualitative content analysis approach, we searched for the factors promoting spirituality among a selection of Iranian older adults. Totally, 22 people aged above 60 years old were interviewed using open-ended questions. The recorded interviews were then transcribed, and a coding process was applied based on a qualitative, conventional content analysis. Three key factors were found to promote the spirituality among the older adults: 1) insight in personal belief, 2) spiritual socialization, and 3) peace of mind. Traditional dimensions, the cultural surroundings, and participants' religious beliefs were apparent in each of the categories. Society's role in making the seniors spiritual role models was very important; moreover the hereafter life on religious grounds seemed to be another important factor in reaching for high levels of spiritual and mystical perfection. Educational interventions based on the elders' needs for spiritual empowering by health care professionals especially with regards to their spiritual based social interactions and reaching peace of mind, will comprise a major part of wellness approaches.
