The effectiveness of a group intervention to facilitate posttraumatic growth among women with breast cancer

Abstract

Objective

This longitudinal study tested the effectiveness of a group intervention designed to facilitate Posttraumatic Growth (PTG). The effects of group participation on components of the PTG model were also explored.

Methods

Sample consisted of 205 women diagnosed with non-metastatic breast cancer who were either assigned to an intervention group (n = 58) or to a control group (n = 147). PTG, challenge to core beliefs, and rumination (intrusive and deliberate) were assessed at baseline (T1), at 6 months (T2) and at 12 months after baseline (T3).

Results

Results from the Latent Growth Modeling suggested that participants from the intervention group had higher levels of PTG. Significant differences were found between both groups, on challenge to core beliefs (T1-T3; T2-T3), intrusive rumination (T1-T3) and deliberate rumination (T1-T3).

Conclusions

Participation in the intervention group increased PTG and the two main components of PTG model, challenge to core beliefs and rumination.
