Development and validation of a self-report for the assessment of adjustment disorders


Einsle, F; Köllner, V; Dannemann, S; Maercker, Andreas (2010). Development and validation of a self-report for the assessment of adjustment disorders. Psychology, Health & Medicine, 15(5):584-595.

Abstract

Based on a recent diagnostic proposal for adjustment disorders a self-report assessment was developed. The current study reports validation results. Psychometric properties were examined using two different samples of 687 patients with cardiac arrhythmias and 86 patients from a psychosomatic outpatient clinic. Besides evaluating the internal structure and re-test reliability, associations with quality of life, general anxiety and depression, symptoms of posttraumatic stress disorder and coping strategies were analyzed. The factor analysis confirmed the three postulated factors: intrusion, avoidance and failure to adapt. The internal consistencies for these three scales were between = 0.74 and 0.91. The re-rest reliability of the scales for a six-week period lay between rtt = 0.61 and 0.84. Medium-sized correlations were found between the scales with general anxiety and depression as well as posttraumatic stress disorder. Furthermore, the scales correlated with emotion-oriented and somewhat with proactive coping, but not with task-oriented or avoidance-oriented coping strategies. It is concluded that the self-report on adjustment disorders enables new possibilities to investigate further previously under-researched adjustment disorders.
