Competing Interests

The data used for the present study were collected as part of a larger study exploring the effectiveness of a telephone-based health coaching (TBHC) intervention, which was funded by the Kaufmännische Krankenkasse Hannover (KKH), Germany. The KKH is a health insurance company that is part of the German public statutory health insurance system. We confirm that the funder (KKH) had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. We further confirm that our relationship with KKH will not affect our adherence to PLOS ONE policies on sharing data and materials.
