Interest in mindfulness-based interventions for children and adolescents is burgeoning, bringing with it the need for validated instruments to assess mindfulness in youths. The present studies were designed to validate among adolescents a measure of mindfulness previously validated for adults (e.g., Brown & Ryan, 2003), which we herein call…

In response to the concern that Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher, W. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989; J. N. Butcher et al., 2001) Variable Response Inconsistency (VRIN) and True Response Inconsistency (TRIN) score invalidity criteria recommended for use with American samples results…

The current study used factor mixture modeling to identify heterogeneity (i.e., latent classes) in 2 well-supported models of posttraumatic stress disorder's (PTSD) factor structure. Data were analyzed from a clinical sample of 405 Canadian veterans evaluated for PTSD. Results were consistent with our hypotheses. Each PTSD factor model was best…

Aberrant salience is the unusual or incorrect assignment of salience, significance, or importance to otherwise innocuous stimuli and has been hypothesized to be important for psychosis and psychotic disorders such as schizophrenia. Despite the importance of this concept in psychosis research, no questionnaire measures are available to assess…

The correlation between a short-form (SF) test and its full-scale (FS) counterpart is a mainstay in the evaluation of SF validity. However, in correcting for overlapping error variance in this measure, investigators have overattenuated the validity coefficient through an intuitive misapplication of P. Levy's (1967) formula. The authors of the…

An eight-subtest short form (SF8) of the Wechsler Adult Intelligence Scale, Third Edition (WAIS-III), maintaining equal representation of each index factor, was developed for use with psychiatric populations. Data were collected from a mixed inpatient/outpatient sample (99 men and 101 women) referred for neuropsychological assessment. Psychometric…

Traditional measures of the therapeutic alliance do not capture the dual roles inherent in relationships with involuntary clients. Providers not only care for, but also have control over, involuntary clients. In 2 studies of probationers mandated to psychiatric treatment (n = 90; n = 322), the authors developed and validated the revised Dual-Role…

Factor models of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) for one, two, three, and four factors were tested using confirmatory factor analysis with a sample of 177 child psychiatric inpatients. The four-factor model proposed in the WISC-III manual provided the best fit to the data. (SLD)

Information on the Beck Anxiety Inventory (BAI) was obtained for psychometric properties, gender differences, and relation to depression for 291 psychiatric patients with a subsample of 251 who completed the Beck Depression Inventory. Two demonstrated BAI factors are discussed, as are male-female differences and correlation with depression. (SLD)

Receiver operating characteristic (ROC) analysis was used to evaluate 11 Minnesota Multiphasic Personality Inventory-2 (MMPI-2) indicators of response distortion using 343 college students, some of whom simulated malingering or defensive responding, 181 forensic psychiatric patients, and 95 other psychiatric patients. Results show the usefulness…

Minnesota Multiphasic Personality Inventories (MMPIs) were administered to an urban mixed-race sample of 218 adolescent psychiatric patients. Wiggins scale elevations for African Americans and whites were compared, and the validity of the scales was assessed through comparison with parent observations. Implications for the MMPI-Adolescent content…
