This study examines the multidimensionality of spirituality by comparing the applicability of two models—the five-dimensional model of religiosity by Huber that we have extended with a sixth dimension of ethics and the three-dimensional spirituality model by Bucher. This qualitative study applied a semi-structured interview guideline of spirituality to a stratified sample of N = 48 secular individuals in Switzerland. To test these two models, frequency, valence, and contingency analysis of Mayring’s qualitative content analysis were used. It could be shown that Bucher’s three-dimensional model covers only about half of the spirituality codes in the interviews; it is especially applicable for implicit and salient spiritual aspects in general, as well as for spiritual experience in specific. In contrast, the extended six-dimensional model by Huber could be applied to almost all of the spirituality-relevant codes. Therefore, in principle, the scope of this six-dimensional model can be expanded to spirituality. The results are discussed in the context of future development of a multidimensional spirituality scale that is based on Huber’s Centrality of Religiosity by extending the religiosity concept to spirituality without mutually excluding these concepts from each other.
