The Psychopathology Instrument for Mentally Retarded Adults. Internal consistencies and relationship to behaviour problems.

The Psychopathology Instrument for Mentally Retarded Adults, a recently developed, empirically derived measure of psychiatric disturbance for the mentally handicapped, gives a total of eight scales which correspond to DSM-III diagnostic categories. This paper reports its psychometric properties in a British population and the psychometric properties of three scales derived by factor analysis. The internal consistencies of the scales were only barely acceptable in this sample and less acceptable than in previous studies.

Psychometric properties of resting anterior EEG asymmetry: temporal stability and internal consistency.

We examined whether resting anterior electroencephalographic (EEG) asymmetry in the alpha frequency band has psychometric properties that would be expected of a measure assessing individual differences. In each of two experimental sessions, separated by three weeks, resting EEG in midfrontal and anterior temporal sites was recorded from 85 female adults during eight 60-s baselines. Resting alpha asymmetry demonstrated acceptable test-retest stability and excellent internal consistency reliability. Analyses including other frequency bands indicated that degree of stability varied somewhat as a function of band and region. In addition, asymmetry was less stable than absolute power. Discussion focuses on the implications of the present findings for the measurement and conceptualization of resting anterior asymmetry.

[Study of the reliability, validity and internal consistency of the LSP scale (Life Skills Profile). Profile of activities of daily living].

The LSP scale (Life Skills profile) has been recently translated and adapted into Spanish language. Its has 39 items and attempts to measure the chronic mental patient functioning in situations and tasks of everyday life. It is brief, jargon free, capable of completion by family members, community housing managers as well as professional staff. Reliability, concurrent validity and internal consistency of this Spanish version are reported. The good performance of LSP in all this measurements give support to its use in research and clinical settings.

Form E of the 16PF and adults with mental retardation: internal consistency and validity.

Form E of the Sixteen Personality Factors Questionnaire (16PF-E) was administered to 70 adults (45 men and 25 women) who resided in a public facility for mentally retarded persons. Alpha coefficients were computed for each of 16 primary trait scales. The Intelligence (B), Ego Strength (C), Dominance (E), Superego Strength (G), Parmia (H), Protension (L), Autia (M), Shrewdness (N), Guilt Proneness (O), and Self-Sentiment (Q3) scales exhibited low internal consistency, whereas Premsia (I) and Self-Sufficiency (Q2) evidence relatively higher levels. Personality traits of subjects were also assessed by staff ratings. Ratings were compared to 16PF-E primary and secondary trait scores via correlation coefficients. Results provided virtually no support for the validity of the 16PF-E primary scales and the Exvia, Anxiety, and Cortertia secondary factors as applied to the subject population. Limited support for the validity of the Independence secondary factor was found.

The reliability and internal consistency of the motivation rating scale and the general trait rating scale.

The Motivation Rating Scale (MRS) and General Trait Rating (GTRS) Scales have been proposed as methods for assessing personality traits of athletes. The scales are easily accessible and are proposed for use as coaching tools. A coach's form and athlete's form of each test was administered to 149 male and female varsity high school basketball players and their coaches in eight different states. Means and standard deviations for all variables as well as test-retest reliability coefficients, trait inter-correlations, correlations between test forms, and Alpha coefficients were calculated. Results suggest that each of the four scales was independent of the others, with the coach's form of the MRS showing reasonable reliability and reasonable internal consistency for selected traits. There is some indication that "trait generalization" among coaches may inflate the test-retest reliability of the coach's form of the MRS. No convincing evidence is presented to support the notion that any of the four scales measure the traits the scales are purported to measure.

Scales for measuring health belief model dimensions: a test of predictive value, internal consistency, and relationships among beliefs.

Critiques of research on the Health Belief Model have been directed at the need for: (1) applying the Model to behavior related to chronic illness; (2) multivariate testing of the major dimensions of the Model; (3) developing reliable scales; and (4) explicating the relationships among the beliefs. In an attempt to respond to these concerns, data are presented from a prospective study of mothers' adherence to a diet regimen prescribed for their obese children. The Model components were found, both singly and in combination, to be correlated with the study's measure of dietary compliance. Multiple regression analysis utilizing five belief indices accounted for a substantial portion of the variance in children's weight change. Questionnaire items employed in creating indices for each Model dimension are presented, together with discussion of the internal consistency of each index. Belief intercorrelations appear to demonstrate that distinct Model dimensions exist.

Dimensionality, internal consistency and interrater reliability of clinical performance ratings.

A total of 6444 ratings of the financial performance of 424 third- and fourth-year medical students were made by house officers and attending teachers during 12 separate internal medicine rotations. Ratings were based on 13 behaviourally anchored rating scales. One rating was randomly selected per student per evaluator type (house officer and attending teacher) during each of the 12 rotation periods. Ratings were factor analysed separately within each rotation period. Two factors emerged consistently, and congruence coefficients across the 12 occasions were high (0.88 or greater). The factors were labelled 'problem-solving (10 items) and 'interpersonal skills' (three items) on the basis of their content. Internal consistency coefficients of the indices constructed from items in the two factors and the total of the 13 items were high (0.9 or greater) and did not differ substantially when computed separately on the ratings from house officers and attending teachers. Interrater reliabilities on the individual items ranged from 0.14 to 0.33.

Completeness and internal consistency of DSM-III criteria for post-traumatic stress disorder.

Clinical observations suggest that anxiety, depression, rage, and alienation might profitably be considered to be criteria for the diagnosis of post-traumatic stress disorder (PTSD). The results of this investigation (N = 69) suggest that inclusion of these variables among the PTSD criteria would be inappropriate. Somatization and/or hypochondriacal fixation, however, appears to be intimately related to combat traumatization and might appropriately be considered for inclusion among the symptoms associated with PTSD. The DSM-III stress-disorder criteria contain five elements that, among substance-abusing veterans, contribute marginally to the diagnosis of PTSD. Accuracy in evaluating for PTSD might not be compromised by considering fitful sleep, concentration problems, memory impairment, memory interference, and survivor guilt to be associated phenomena rather than PTSD criteria. The results are generally consistent with modifications in diagnostic practice suggested in DSM-III-R.

Internal consistency of the Northwestern Syntax Screening Test.

This study was designed to evaluate the usefulness of the 40 receptive and 40 expressive items of the Northwestern Syntax Screening Test. Twenty preschoolers with normal language development, 20 preschoolers functioning within the range of normal intelligence diagnosed as language impaired, and 20 mentally retarded children comprised the three subject groups. The subjects were equated for mental age. Stable Hoyt's reliability coefficients indicated that the Northwestern Syntax Screening Test assessed consistently the syntax and morphology used by children with atypical language development. Detailed item analysis revealed the strengths and weaknesses of both receptive and expressive items.
