In Study Two, we evaluated the role of disproportionality in understanding the impact of cognitive change procedures on client's experience of cognitive change. We evaluated this in a sample of 126 clients participating in CBT for depression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In Study One, evaluation of the PDR\u2010S revealed good model fit for a single factor solution. The PDR\u2010S was positively related to cognitive reactivity and maladaptive coping responses; it was negatively related to adaptive coping. Most relations were still significant when neuroticism and depressive symptoms were included as covariates. In Study Two, disproportionality moderated the relation between cognitive change procedures and cognitive change, with a stronger positive relationship when participants self\u2010reported a more disproportionate depressive reaction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings support the use of the PDR\u2010S as a brief measure of disproportionality.
