A Gestalt process/action based theory of depression and test construction validation

The primary goal of this study was to establish a new way of assessing depression in children based on a theoretical model of depression as process rather than the outcome. As such, a new measure, the DPS-C, was constructed based on Gestalt theory's perspective on the process of depression, which differs substantially from existing measures due to its focus away from DSM symptomatology. Having needs, the recognition/awareness of those needs and taking action towards meeting the needs is defined as a core concept of the process of depression with Gestalt theory. When this process is disrupted, psychopathology arises. Depression results from repeated occurrences of unmet needs, until these desires are no longer part of awareness (i.e., chronic depression). The findings demonstrated the theoretical construct, internal validity and predictive validity of the DPS-C. Furthermore, the 13 item final measure met the reliability requirements. Study findings also showed the new measure to have construct and discriminate validity.
