 Duration of the study Group intervention in the treatment arm consists of 16 weeks of the CALM program. Due to the limited number of participants we can allocate to each group, three 16 weeks cycles will be repeated in order to recruit the needed number of participants for the trial. Thus the treatment phase is expected to last for 48 weeks. Recruitment is expected to last about three months. An additional 6 months will be required for completion of data entry and analysis.
