Background for and development of a brief Adult Behavioral Classification Project Inventory.

An abridgement of the Adult Behavioral Classification Project Inventory (AdBCP) was accomplished. The creation and development of the full-scale Inventory is described in Phase I. In Phase II, the participant pool was divided into half, and each half of the data set was subjected to both exploratory and confirmatory factor analyses with a factor control of 11 of the strongest factors in the original data set. Items identifying these factors had to have at least magnitude of .35 factor structure weights, leaving a 42-item instrument, the Brief AdBCP Inventory. Predicting from the first half to the second half by confirmatory factor analysis resulted in a fair confirmation of the factor structure. A rough norm table is offered based on the factor scores of the first half of the participants' records.

A further validation of the children's behavioral classification project inventory.

To add evidence of the validity of the Children's Behavioral Classification Inventory, the response of parents and teachers were compared on a set of 110 items of the inventory which describe behaviors equally observable to both groups. The two sets of data were subjected in Phase I to principal components analysis to extract two factors in each case which were compared by means of the Ahmavaara transformation and found to be highly comparable. In Phase II, predictions were made from factor weights of 36 items measuring six factors in the original standardization of the inventory to both sets of respondents' data by means of confirmatory factor analysis. The formal indices of comparability were not generally in acceptable ranges; however, substantively the six factors were definitely replicated in the two samples.

Background for and development of a brief Children's Behavioral Classification Project Inventory.

A brief form of the Children's Behavioral Classification Project Inventory was developed. A Proto-CBCP Inventory consisting of 229 behavioral items and 11 demographic variables was administered to 351 parents of children with clinical problems and 80 normal control parents. The analyses of these data were thoroughly criticised by experts in psychology and related fields. From this critique and trial runs which included 22 demographic variables, a full inventory of 274 behavioral items plus child's age, sex and clinic vs nonclinic status resulted; this inventory has a 30-factor structure. Given the length of the full-scale inventory and the number of factors derived from it, a briefer form was created consisting of 189 items from which were derived 13 factors. This inventory was standardized on a total n of 1379 for use as a screening device in clinics.

Prediction of recreational therapy behavior of hospitalized adolescents from a behavior classification instrument.

The purpose of this study was to estimate the validity of an instrument of the Adolescent Behavioral Classification Project in predicting behavior patterns of emotionally disturbed adolescents in an inpatient setting. Subjects (n = 126) were adolescents admitted to a state residential treatment unit across a period of 35 months. Predictor variables were scores on 17 or 25 factors of the instrument from both adolescents' own responses and their mothers' responses on their behalf. Criterion variables were 10 recreational therapy factors, especially 4 temporally stable factors, and length-of-time in treatment. 3 phases of the project were (I) behavior during initial stages of the therapy, (II) behavioral change after 3 months of therapy, and (III) length-of-time in treatment. In Phase I, both mothers' and adolescents' responses produced significant correlations with criteria; however, in Phase II only the adolescent students' 25 ABCP factors predicted behavioral change. In Phase III, adolescents' responses but not their mothers' responses classified the adolescents by length-of-time in treatment.

An Autonomic Nervous System Response Inventory (ANSRI): scaling, reliability, and cross-validation.

The Autonomic Nervous System Response Inventory (ANSRI) was designed to elicit individuals' self-reported patterns of peripheral physiological response to emotion-provoking stimuli. Fifty-one items reflecting such responses were rated as having been present (1 = absent to 5 = intense) during prototypical emotional situations drawn from experience, which were reconstructed and imagined by a subject. Items were rated for each of five conditions, four of which were emotions (fear, anger, sadness, joy) and one of which was an activation control condition (physical activity). Scales were developed to describe the relative activity of different physiological response systems: P scales based on physiological coherence of items and F scales based on factor analytic item clusters. The derivation and contents of the scales are described, and the following psychometric data are reported: test-retest reliabilities and internal consistency coefficients (original and cross-validation samples), factor analyses, and cross-validation of factors. Data indicate that the ANSRI and most of its scales are sufficiently reliable and replicable to warrant validity research.

The initial standardization of the Adolescent Behavioral Classification Project Instrument.

An instrument has been developed through the Adolescent Behavioral Classification Project for assessing an adolescent's problems and for establishing a taxonomy of behaviors and of persons. Standardization has initially consisted of collecting from many sources 482 statements of problem behaviors and 30 "positive" behaviors, which can be observed by nonprofessional as well as professional persons; administering these behavior statements to 156 institutional and 94 noninstitutional mental health center adolescents and 376 of their parents; carrying out principal components analyses on the behavioral items and 3 demographic items, followed by Varimax and Promax rotations. Twenty-five factors scored on 410 items resulted from these procedures. Internal consistency coefficients for the factors range from .47 to .86. Test-retest reliabilities on a sample of 10 youths ranged from .24 to .94, with an average rtt of .71. Factor scores for different classes of respondents were fairly well correlated from one set to another. The different classes of respondents did not differ significantly from one another on "caution" items. Similarities are noted, by inspection, between these factors and those derived from the Children's Behavioral Classification Project and between those other authorities have set forth and the ABCP.

Sculpture preferences and personality traits.

Factor analyzed the preference ratings of 70 male and 70 female undergraduates for 36 slides of sculpture. A principal factors solution with orthogonal rotations yielded 6 factors: ambiguous abstraction vs. controlled human realism, mildly distorted representation, emotional detachment, traditional portraiture vs. surrealism, highly distorted representation, and geometric abstraction. Some of these factors were similar to the Apollonian, the Dionysian, and the Pythagorean dimensions previously postualted by Nietzsche and Knapp. Preference scores for each factor were computed and correlated with scores on the 16 PF and with selected educational and physical variables. A few small, significant (p less than .05) correlations were found, supporting the hypothesis that artistic style preferences resemble the personality traits of the spectator.
