Robustness of the maximum-likelihood estimation procedure in factor analysis

In order to determine the robustness of the maximum-likelihood estimation procedure, random variates from six distributions were generated independently on a high speed computer and then used to represent the common and specific factors in a factor analysis model in which the coefficients of these factors had been specified. Using Lawley's approximatex ² statistic in evaluating the estimates obtained, the estimation procedure is found to be insensitive to changes in the distributions considered.This study was conducted while the authors were members of the Statistical Laboratory at Iowa State University. All computations were done at Iowa State on an IBM 7074.     

Rational-Emotive Behavior Therapy in the Treatment of Adult Victims of Childhood Sexual Abuse

This study investigated the effectiveness of Rational-emotive behavior therapy in the treatment of adult victims of childhood sexual abuse. A sample of 42 women, seeking help for their psychological distress associated with childhood sexual abuse, was selected by means of an assessment interview and the Trauma Sympton Checklist, and randomly assigned to a treatment (n=28) and a delayed treatment control group (n=14). The treatment group participated in 10 weekly sessions of group Rational-emotive behavior therapy and was followed up 8 weeks after termination of treatment. Repeated measurements were obtained by means of the Beck Depression Inventory, State-Trait Anxiety Scale, State-Trait Anger Scale, Guilt Inventory, Coopersmith Self-Esteem Inventory and Golombok-Rust Inventory of Sexual Satisfaction. Results indicated significant reductions in depression, State anxiety, State anger, State guilt and low self-esteem. These improvements were maintained at follow-up.     

Prevalence of anxiety among patients undergoing colorectal surgery

To assess prevalence of anxiety 36 consecutive patients undergoing colorectal surgery with general anesthesia were interviewed on the day of surgery and completed the State-Trait Anxiety Inventory. Postsurgical ratings of pain and anxiety were obtained within 24 hours after surgery. Analysis indicated that 29 scored moderate or higher on the State Anxiety scale prior to surgery. The correlations for scores on presurgical Trait Anxiety with postsurgical pain and Trait Anxiety scores were significant (p<.01) but not that for pre- and postsurgical State Anxiety     

Functionplane—A new approach to simple structure rotation

A new criterion for rotation to an oblique simple structure is proposed. The results obtained are similar to that obtained by Cattell and Muerle's maxplane criterion. Since the proposed criterion is smooth it is possible to locate the local maxima using simple gradient techniques. The results of the application of the Functionplane criterion to three sets of data are given. In each case a better fit to the subjective solution was obtained using the functionplane criterion than was reported for by Hakstian for the oblimax, promax, maxplane, or the Harris-Kaiser methods.This paper is contribution No. 66 from the Program in Ecology and Evolution at the State University of New York, Stony Brook, New York.

On the interrelations of syntax and semantics

Summary Proceeding from the assumption that the recall of sentence tense is affected by verb meaning, the following variations in verb meaning were introduced: Action vs. State and Terminal vs. Interminal. The influence of these aspects on the recall of the Present and Perfect tenses (in German) was tested in a three-factorial design. A distinct interaction was obtained between the factors Terminal/Interminal and sentence tense. The Action/State condition did not affect the recall of sentence tense. All tested aspects of verb meaning did however influence the recall of sentence content.The author gratefully acknowledges the assistance of Mr. B. Jankowski in the translation of this paper from an original German version.     

Anxiety and locus of conflict in emotionally disturbed children

The State Trait Anxiety Inventory for Children (STAIC) and the Children's Manifest Anxiety Scale (CMAS) were administered to 50 emotionally disturbed children (40 males and 10 females). In addition, ratings on a Locus of Conflict Rating Scale were obtained from their special education teachers. Significant correlations were obtained between all anxiety measures. However, anxiety, as measured by the CMAS, A State and A Trait, was not significantly correlated with the ratings of internalization, externalization, or the total maladjustment index. Girls reported greater anxiety than boys on the CMAS and the STAIC A Trait scale, while boys were rated as significantly higher on the internalization and externalization scales, and in total maladjustment.     

A short-term longitudinal study of the early development of self-regulation

A short-term longitudinal study was conducted to determine whether self-regulation at 4 years could be predicted from child and maternal measures obtained when the children were age 24 months. The subjects were 69 children and their mothers drawn from the general community. Criterion behaviors assessed at 4 years were those suggestive of attention-deficit hyperactivity disorder. Of the 24-month child measures, maternal ratings of the child's impulsivity and attention span, plus an objective measure of delay ability, were the most effective predictors. Maternal negativity, as assessed in mother-child interaction, predicted the criterion behaviors, even after the child's behavior as an elicitor of maternal behavior was controlled. Maternal child-rearing attitudes on the dimensions of warmth and aggravation were also effective predictors, even after controlling for the child's emotionality as a possible determinant of maternal attitudes. It is argued that the results with the maternal attitude measures provide support for the hypothesis that maternal behavior is a contributor to the development of self-regulation.This research was supported by a State of Ohio Academic Challenge Grant to the Bowling Green State University Clinical Psychology Program, and by a Basic Grant awarded to the first author by the Bowling Green State University Faculty Research Committee.

Clinically Significant Change After Cognitive Restructuring for Adult Survivors of Childhood Sexual Abuse

This study investigated the outcome of cognitive restructuring for adult survivors of childhood sexual abuse in terms of clinically significant change. Twenty-six participants were assessed for depression, State anxiety, State anger, State guilt and self-esteem before and after 10 weekly sessions of group Rational-emotive behavior therapy, and at follow-up after 8 weeks. In contrast to a previous analysis of the data in terms of statistical significance, indicating significant improvements on all variables from pre- to posttreatment, an analysis based on clinically significant change showed a differentiated treatment effect. Cognitive restructuring was found to be highly effective in facilitating recovery on anxiety, depression and anger, but less effective for guilt and low self-esteem. Only 3 patients (11, 54%) recovered on all 5 variables, while 10 patients (38, 46%) showed recovery on at least 4 variables. Relationship to the perpetrator and pre-treatment irrational evaluative beliefs (measured by means of the Survey of Personal Beliefs) were found to be the best predictors of treatment outcome. A poor response to treatment was associated with the perpetrator being a close family member and with more Other-directed Shoulds, while recovery was associated with the perpetrator being a friend or stranger and with more Awfulizing, Self-directed Shoulds and negative Self-worth beliefs.     

Measuring Obsessions Without Worry: Convergent and Discriminant Validity of the Revised Padua Inventory in an Icelandic Student Population

The revised Padua Inventory (Padua Inventory-Washington State University Revision or PI-WSUR) was investigated in an Icelandic student population ( n = 431). The inventory was explicitly constructed to minimize the overlap between the measurement of obsessionality and worry. Its relationships with the Maudsley-Obsessive-Compulsive Inventory (MOCI) and the Penn State Worry Questionnaire (PSWQ) were investigated. The factor structure of the PI-WSUR was studied as well as the relations of PI-WSUR subscales with corresponding scales on the MOCI (checking, contamination). It was further investigated whether a factor analysis of the PI-WSUR together with PSWQ would indicate that the PI-WSUR and its different components were relatively uncontaminated by variance shared with worry. The results generally supported the psychometric properties of the Icelandic version of the PI-WSUR as well as its relative independence of PSWQ specifically.     

The development and validation of Spanish versions of the State and Trait Food Cravings Questionnaires

OBJECTIVE: We developed and tested the psychometric properties of Spanish versions of the Trait and State Food Cravings Questionnaires (FCQ-T and FCQ-S respectively). METHOD: The instruments were translated and adapted to Spanish and administered to undergraduate students from a Southern university in Spain (N = 271). The data were analyzed using confirmatory factor analysis to compare the factor structure of the English and Spanish versions of both questionnaires. RESULTS: The factors structure of both questionnaires obtained excellent fit indices across their Spanish versions with the one exception that some factors of the FCQ-S were more highly intercorrelated among the Spanish sample than the American. DISCUSSION: This study supports the conceptualization of food cravings as universal multidimensional motivational states that can be reliably measured and supports the use of the Spanish versions of the FCQ.     

Comparison of matching and drawing in the perception of shape at various intelligence levels

The Pennsylvania State University, University Park, Pennsylvania 16802 The tendency toward shape constancy was investigated using both the traditional matching technique of Thouless and free-hand drawing of the stimulus object. Data were obtained for college students and for institutionalized feebleminded Ss at three levels of intelligence. The previous observation that Ss of higher intelligence level produce a lower tendency toward shape constancy, as measured by the matching method, was confirmed. With the drawing method, the same trend was observed but the differences among groups were exaggerated. The sensitivity of measures of perceived shape to experimental as well as nonexperimental variables is discussed.     

Efficient estimation and local identification in latent class analysis

Aerobic conditioning and stress reduction: Participation or conditioning?

The efficiency of an aerobic conditioning program (jogging) is compared to cognitive therapy (stress inoculation) and a waiting list control in modifying self-reported chronic stress. The participants were community residents; 48 were females and 25 were males. Treatment sessions were conducted over a 10-week period with subjects meeting in small groups for 1$\text{1}\text{2}$ hours per week. The State/Trait Inventories, a Tension Thermometer and a submaximal bicycle ergometer test were administered pre, post and follow-up. Repeated measures, multivariate analysis of variance indicated that both treatments were effective in reducing stress compared to the waiting list control and that these changes were maintained at 3-month follow-up. Multivariate analysis indicated that participants with higher initial levels of aerobic fitness did not report less stress, while participants who obtained higher levels of fitness during the conditioning program fared no better in reducing stress than their counterparts who obtained lower levels of aerobic fitness. These findings are of interest because they suggest that the psychosocial components of the fitness program were active ingredients of treatment rathee than the effects of improved cardiovascular functioning.     

The relationship between auditory discrimination and oral production of Spanish sounds in children and adults

The purpose of this study was to investigate the question of age in relation to second-language learning. Specific variables investigated were the auditory discrimination and oral production of Spanish sounds. Two test were constructed: (1) The auditory discrimination test used minimal pairs of Spanish sounds, and (2) the oral production test used words that differed in only one sound. Both tests were given individually to a group of randomly chosen English monolingual speakers. A group of children (1 st-graders) and a group of adults (12th-graders) were tested to determine if both tests taken together would show one group to have a higher foreign language aptitude than the other group. While it was hypothesized that children would perform better than adults, the multivariate analysis of variance indicated that, with both tests taken together, adults were superior in auditory discrimination and oral production, supporting the idea that adults because of their cognitive advantage and maturity are more efficient and successful in these two aspects of foreign-language learning. Children did not exhibit the facility that early-foreign-language-learning advocates have postulated.This article is based on a dissertation submitted by Alba A.

Factor structure of the state-trait anxiety inventory for children

The State-Trait Anxiety Inventory for Children was administered to 644 children in grades 4, 5 and 6. The intercorrelations among the 40 STAIC items were subjected to a principal components analysis using unities in the diagonals. Orthogonal rotations were then performed via the Varimax procedure. Examination of the 6, 5, 4, 3 and 2 factor rotations indicated that the three factor solution was best in terms of simple structure and psychological meaning. The three factors that emerged were: Trait Anxiety, State Anxiety Present, and State Anxiety Absent.     

Psychometric revision and differential item functioning in the State Trait Anxiety Inventory (STAI)

One of the psychological problems with highest prevalence is anxiety. The State Trait Anxiety Inventory is one of the instruments to measure it. This questionnaire assesses Trait Anxiety (understood as a personality factor that predisposes one to suffer from anxiety) and State Anxiety (refers to environment factors that protect from or generate anxiety). The questionnaire was adapted in Spain in 1982. Therefore, the goal of the study is to review the current psychometric properties of the STAI. A total of 1036 adults took part in the study. Cronbach's alpha reliability was .90 for Trait and .94 for State Anxiety. Factor analysis showed similar results compared with the original data. Moreover, differential item functioning (DIF) was carried out to explore sex bias. Only one of the 40 items showed DIF problems. Lastly, a t-Test was run, comparing the original and current values; whereas Trait Anxiety varied in 1 point, State Anxiety had differences of up to 6 points. In general, this result shows that the STAI has maintained adequate psychometric properties and has also been sensitive to increased environmental stimuli that produce stress.     

Reliability and validity of a cost-efficient sociometric measure

Sociometric measures have been used frequently to measure social status; however, reliable sociograms for young children usually involve time-consuming administrations. A group-administered, peer-rating sociogram, the Sociometric Peer-Rating Scale (SPRS), was devised and given to 217 first and second graders. Concomitantly, teacher nominations of children most liked, aggressive, or withdrawn and behavioral observations of the high- and low-SPRS children were obtained. After 7 months, the SPRS was readministered. On a separate population of eight kindergarten children, this sociogram and a similar, individually administered sociogram were given. Normative data, test-retest reliability, and split-half reliability were reported. The test-retest reliability was comparable to the reported reliability of other peer-rating sociograms, and the SPRS correlated significantly with teacher ratings of aggressiveness and likability and with the individually administered sociogram. The number of positive interactions was significantly different for high-versus low-SPRS children. The usefulness of the SPRS as a measure of social competence was discussed.This research was submitted by the author in partial fulfillment of the requirements of a master's degree at the Florida State University.I would like to thank the Master's committee, Wallace Kennedy, William Pelham, and Joseph Torgesen, and the participating schools, Developmental Research School of Florida State University and Woodville Elementary School of the Leon County School District, for their assistance in this study.     

Rigidity in Parent—Child Interactions and the Development of Externalizing and Internalizing Behavior in Early Childhood

Behavioral rigidity is a common feature of many psychopathologies, yet the association between rigidity and the development of childhood psychopathology has not been studied. State space grids (a dynamic systems [DS] method) were used to examine the relation between rigidity in parent-child interactions and childhood externalizing and internalizing problems. High-risk kindergarten children (n = 240) and their parents were observed for 2 hr engaging in a variety of tasks that were expected to elicit a range of affect. State space grid analysis of the observational data revealed an association between rigidity in parent-child interactions and child externalizing behavior problems in the fall and spring of kindergarten and 1st grade, and with growth in those problems over time. Rigidity was associated with concurrent levels and with chronic high-level internalizing problems. Strengths and limitations of the new DS methodology in relation to understanding child psychopathology are discussed.     

Structure of the Mini-Mental State Examination: a comparison between normal and clinical subjects

The Mini-Mental State Examination was administered to a sample of 133 Italians ranging from 60 to 80 years of age. From a Principal Components Analysis three factors were retained, being results of both varimax and oblimin rotations. These were labeled (1) Memory, (2) Verbal Comprehension, and (3) Attention. These factors are similar to those obtained with normal elderly Americans, but they are different from the factors based on clinical samples. No age differences in the factor scores were found among the normal elderly subjects when education was considered. In contrast, significant differences were found between a group of 25 demented patients and a matched group randomly extracted from the normal sample.
