We examined the psychometric properties of the Assessment of Depression Inventory (ADI). This instrument assesses depression and also has validity scales that address response honesty. Three studies were conducted. The first describes the development of the ADI. The second compared the concurrent validity of the ADI Depression (Dep) scale with the BDI-II, and the ADI Feigning (Fg) scale responses of psychiatric inpatients with those of a sample of community volunteers asked to feign depression. The third study was used to cross-validate the results with a separate sample of participants. The ADI Dep scale correlated highly with the BDI-II. Significant differences were also found between the honest patient responders and the non-patient feigners on the Fg scale. The data supports the ADI validity scales as measures of response style and the Dep scale as a measure of depression.

This study examines the validity rates of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and Personality Assessment Inventory (PAI) profiles in a rural inpatient population. The validity scales of 90 MMPI-2 and 90 PAI profiles were analyzed using published criteria for determining validity. Random responding, positive impression management, and negative impression management were also evaluated. The PAI had a higher number of valid profiles compared with the MMPI-2. Evidence suggests the primary source of the invalid profiles within the MMPI-2 is a higher level of endorsement of relatively rare statements. The substitution of the Infrequency-Psychopathology scale (Fp) for the Infrequency scale (F) on the MMPI-2 substantially reduced the number of invalid profiles. Contrary to expectations, the PAI did not demonstrate lower levels of invalid profiles due to random responding. Rates of invalid profiles for each scale are provided.

Token economies are an effective way of changing various behaviors including acquiring new skills, reducing undesired behaviors, reducing aggression, increasing treatment compliance, and improving psychiatric unit management. This study examines the long‐term effect of a token economy on an acute care, inpatient psychiatric unit. The two years following the implementation of a unit based token economy are compared with the 12 months prior to implementation. The results show a significant reduction in total assaults as well as fewer staff injuries resulting in loss of time from work. Copyright © 2003 John Wiley & Sons, Ltd.
