Geetanjali Basarkod, Student Representative

Geet is a PhD candidate at the Institute for Positive Psychology and Education, Australian Catholic University, and is supervised by Prof. Joseph Ciarrochi and Dr. Baljinder Sahdra. Her thesis is based squarely within the CBS framework. Specifically, she is creating a clinical tool to assess the frequency and motivation for six behavioural patterns that promote well-being, that will hopefully help practitioners increase their clients’ valued activity.

She was introduced to ACT during her bachelor’s degree at the University of Warwick in England. Under the supervision of Dr. Nic Hooper, she compared the effectiveness of brief cognitive defusion and thought distraction interventions in dealing with negative thoughts arising from completing a learned helplessness program. She has been greatly interested in CBS and ACT research ever since.

As student rep, Geet aims to further involve the student members with the ACBS community to enable them to learn as much as possible from the current practitioners, academics, and other prominent members. This will equip the students to become future leaders of the association and also set up future collaborations.
