Psychological functioning 1 year after a brief intervention using micronutrients to treat stress and anxiety related to the 2011 Christchurch earthquakes : a naturalistic follow-up . OBJECTIVE We investigated whether micronutrients given acutely following the Christchurch earthquakes continued to confer benefit 1 year following the treatment . METHODS Sixty-four adults from the original 91 participants experiencing heightened anxiety or stress 2-3 months following the 22nd February 2011 earthquake and who had been randomized to receive three different doses of micronutrients completed on-line questionnaires assessing mood , anxiety , stress , and symptoms associated with post-traumatic stress disorder 1 year after completing the initial study . Twenty-one out of 29 nonrandomized controls who did not receive the treatment also completed the questionnaires . RESULTS Both the treated and control groups experienced significant improvement in psychological functioning compared with end-of-trial . However , treated participants had better long-term outcomes on most measures compared with controls ( ES=0.69-1.31 ) . Those who stayed on micronutrients through to follow-up or stopped all treatment reported better psychological functioning than those who switched to other treatments including medications . About 10 % of the sample continued to have post-traumatic stress disorder symptoms . CONCLUSIONS Disaster survivors improve psychologically over time regardless of receiving intervention ; however , those taking micronutrients during the acute phase following a disaster show better outcomes , identifying micronutrients as a viable treatment for acute stress following a natural disaster with maintenance of benefits 1 year later .
