In recent years, positive effects of religiosity and spirituality on mental health can be found as well documented in the literature. However, very few studies examined the effects of a spiritual intervention technique among psychiatric patients. For this reason, in this pilot study we examined the effect of a morning body-oriented meditation in comparison to a conventional morning walk in regards to subjective well-being and stress coping styles in 44 randomly assigned psychiatric-patients (22 females). The patients? amount of subjective well-being as well as their coping ability were assessed at the beginning and at the end of a six weeks therapy. Thereby we found a significant increase in religious/spiritual well-being (p<.01), awareness (p<.01) and more adequate stress coping (at least p>.05), respectively. This was paralleled by a decrease of psychiatric symptoms (p<.01). Overall the general assumption of a positive association between spirituality and mental health was affirmed (p<.01). However, we found no differences between the two treatment methods (meditation vs. morning walk; p>.05). Both interventions showed the same positive efficacy. Based on these initial results, possibilities and boundaries for the integration of religious/spiritual issues into the treatment of psychiatric patients are discussed.
