Following loss, people can develop symptoms of depression, Post-Traumatic Stress Disorder (PTSD), or Complicated Grief (CG) -also termed Prolonged Grief Disorder (PGD). A recent cognitive-behavioural model has proposed that avoiding confrontation with the reality of the loss (called "anxious avoidance" [AA]) and refraining from activities that could foster adjustment (called "depressive avoidance" [DA]) both play a critical role in CG/ PGD. The present study examined this assumption, using self-reported data from 161 mourners. Findings showed that items constituting AA and DA represented two distinct factors. Both factors were strongly correlated with other measures of bereavement-related avoidance and both accounted for a unique part of the explained variance in CG/PGD severity, beyond relevant background variables, negative cognitions, and concomitant symptom-levels of depression and PTSD. DA also explained unique variance in depression beyond these variables. Moreover, AA and DA mediated the linkages of neuroticism, attachment anxiety, and attachment avoidance with symptomlevels of CG/PGD.
IntroductionThere is increasing evidence that in an estimated 5 to 20% of bereaved people a loss gives rise to serious mental health problems such as depression, Post-Traumatic Stress Disorder (PTSD), or Complicated Grief (CG;Forstmeier & Maercker, 2007;Prigerson & Jacobs, 2001). CG, or Prolonged Grief Disorder (PGD) as it is recently termed, entails chronic, intense grief-reactions including separation distress, difficulties accepting the loss, preoccupation, and recurrent images of the lost person that cause significant impairments in functioning for at least 6 months (Prigerson, Horowitz, Jacobs, Parkes, Aslan, Goodkin et al., 2009;Prigerson, Vanderwerker, & Maciejewski, 2008). Parallel to the development of validated criteria for CG/PGD, there is increasing attention for the treatment of this condition. For instance, Shear, DOI: http://dx.doi.org/10.5334/pb-50-1-2-49 50 ANXIOUS AND DEPRESSIVE AVOIDANCE IN GRIEF, Frank, Houck, and Reynolds III (2005) found "complicated grief treatment" -a novel treatment containing elements of interpersonal therapy and cognitive-behavioural therapy (CBT) -to be effective in the reduction of CG/PGD symptoms. Boelen, de Keijser, van den Hout, and van den Bout (2007) found evidence for the effectiveness of brief cognitive-behavioural therapy for CG/ PGD. Although these findings are encouraging, not all patients included in these studies improved, leaving room to further improve and refine treatments. For the refinement of effective treatments for CG/PGD, it is essential to have more knowledge about intrapersonal processes that are involved in the development and maintenance of this condition.Recently, we developed a cognitive-behavioural (CB) conceptualisation of CG/PGD that was designed to offer a framework for the generation of hypotheses about processes involved in this condition and to inform efficacious treatment for it . This model proposes that CG/PGD develops and persists under t...
