A method to optimize the response range while maintaining Rorschach Comprehensive System validity.

Résumé

Brief and lengthy Rorschach records have been identified as common problems in protocol administration. Clinicians have debated how to prevent overly short and long records, but they have been reluctant to alter standardized administration for fear of introducing bias. The present study examines a nonintrusive method for constraining responses by prompting for an extra response when only one is offered per card and by removing the card after four responses are given. Among patients who typically produce brief records, consisting of a residential sample of civil and forensic patients with a range of disordered thinking, the alternative administration method demonstrated improved Comprehensive System validity in assessing thought disorder and eliminated the need to readminister the test due to fewer than 14 responses. The findings have clinical implications for protocol administration with thought-disordered populations that typically produce brief records.
