Planned data acquisition continues documenting the impact of a Service Animal Training Intervention on U.S. Military Veterens in treatment for chronic severe PTSD. Enrollment has been slower than planned however, we are on track to accrue 80 of our planned intensive and non-dog completers due to extension of the recruitment period and lower than expected withdrawals. To summarize across published and preliminary results, canine companionship is associated with improved subjective mood, modification of attentional bias away from negative and toward positive stimuli, attenuated defense responses, and modest reductions in waking heart rate. To date, effects on sleep have not been observed.
