For my systematic analysis of meditation studies, because of the relatively small number of studies available for analysis, the many different meditation techniques were grouped into 5 thematically related categories. These were:

  1. Relaxation Response and studies describing the intervention as based on it.
  2. The MBSR and studies describing the intervention as based on it.
  3. TM and studies describing the intervention as based on it.
  4. Multimodal interventions of which meditation is one part, such as yoga, lifestyle strategies etc.
  5. Miscellaneous, where only a few studies had been conducted on a particular technique and/or when a technique did not easily fall into one of the previous categories.
