One month test-retest reliability of the Revised Psychopathy Checklist (PCL-R) was examined in 88 methadone-maintained males, along with effects of increased information about patients on PCL-R scores and diagnostic derivations. Test-retest reliabilities are quite good. Other findings also confirm potential utility of the PCL-R for research. (SLD)

This article describes a method for the intraindividual clinical validation of a cognitive case formulation (CCF) involving hypotheses about the patient's idiosyncratic cognitive schema (ICS). The two-stage approach begins by testing the convergent and discriminant validity of the hypothesized ICS against the individual's daily ratings of…

Thirty-eight elderly control subjects performed better than did 18 patients with moderate Alzheimer's disease (AD), 33 with severe AD, and 12 with Parkinson's dementia on all measures of the Rey Auditory Verbal Learning Test. Results indicate that the test is useful in distinguishing AD from Parkinson's dementia. (SLD)

Thurstone's scaling based on judgments of 527 students and 37 clinical faculty members was applied to the Beck Depression Inventory, the Zung Depression Scale, and the Minnesota Multiphasic Personality Inventory and fitted the observed data well. A psychological continuum was derived for severity of depression. (SLD)

Validities of the Harris-Lingoes subscales and MacAndrew scale of the Minnesota Multiphasic Personality Inventory (MMPI) in estimation of criterion measures were evaluated with 177 adolescent inpatients. Results were consistent with predictions that excitatory and inhibitory scales and subscales would be related to criteria of behavioral control…

This introduction to a special section provides the basic definitions and presents the measurement approaches and data analytic techniques that are collectively referred to as chaos theory. The conceptualization and assessment of unstable behavioral disorders can be strengthened by incorporating elements of chaos theory. (SLD)

Four validity scales were developed for the Neuropsychology Behavior and Affect Profile using data from clinical and nonclinical samples. A second study, which involved 157 subjects, indicated that combinations of the clinical and validity scales effectively differentiated dissemblers from brain injury patients, even when dissemblers were highly…

Item response theory and the graded response model were used to examine measurement qualities of the Mississippi Scale for Combat-Related Posttraumatic Stress Disorder, with data from 2,348 veterans (participants in the National Vietnam Veteran's Adjustment Study). Implications for improved assessment of posttraumatic stress disorder are…

A developed computer-administered form of the Hamilton Anxiety Scale and the clinician form of the instrument were administered to 214 psychiatric outpatients and 78 community adults. Results support the reliability and validity of the computer-administered version as an alternative to the clinician-administered version. (SLD)

The level of agreement between the patient and a collateral source with regard to depressive symptomatology was compared for 185 patients with Alzheimer's-type dementia (AD), 57 patients with Parkinson's disease, and 54 nondemented geriatric referrals. Findings highlight the potential insensitivity of patient report in AD. (SLD)

In a counterbalanced, within subjects, repeated measures design, 130 undergraduates were administered the Computer-Assisted Hypnosis Scale (CAHS) and the Stanford Hypnotic Susceptibility Scale and were hypnotized. The CAHS was shown to be a psychometrically sound instrument for measuring hypnotic ability. (SLD)

A new instrument, the Social Phobia and Anxiety Inventory for Children (SPAI-C), was developed. Results from 6 studies with nearly 600 children indicate that the SPAI-C is a reliable and valid measure for childhood social anxiety and fear. It may be useful for improving clinical assessment and documenting treatment outcomes. (SLD)

The utility of the Negative Treatment Indicators Minnesota Multiphasic Personality Inventory-2 Content and Content Components scales was evaluated using 113 men treated for chronic pain. Correlates for this patient sample were similar to those of the normative sample. Negative treatment scores may be used to indicate emotional stress. (SLD)

Only the Social Withdrawal and Social Competence subscales of the Child Behavior Checklist (CBCL) tapped a Social Competence factor in common with Social Competence subscales from a parent rating scale (Social Skills Rating System) and a scale (Pupil Evaluation Inventory) for teachers. Mothers of 93 boys (aged 7 to 11 years) completed the CBCL.…

In the context of developing assessment instruments in psychology, issues of standardization, norming procedures, and test reliability and validity are discussed. Criteria, guidelines, and rules of thumb are provided to help the clinician with instrument selection for a given psychological assessment. (SLD)
