The concept of Recovery has taken on new meanings in recent years. Traditional emphasis on diagnosis and repair, has been steadily replaced with the notion of developing and maintaining psychological wellness. This study examined Wellness Recovery Action Planning (WRAP), as a possible intervention in mental health management.  A between groups case cohort design was employed to examine the effects of WRAP with Mental Health and ABI populations, as well as their respective wait list control counterparts. Cohen’s d showed large effect sizes in the difference between treatment and respective control groups in the reduction of Anxiety and Depression, measured by the HADS, for both the ABI ( Cohen’s d for Anxiety  1.03; Cohen’s d for Depression  1.73 ) and Mental Health cohorts ( Cohen’s d for Anxiety 1.29; Cohen’s d  for Depression 1.13). Results demonstrate the potential of WRAP in offering a fresh, twenty-first century perspective, in the functional management of mental health.  Prior to this study, there was no evidence of WRAP having been trialled within the context of ABI, and based on the results indicated, it may indeed be a worthy contender in the everyday management of mental health across populations.
