Interrater reliability of teacher rating scales for children with attention-deficit hyperactivity disorder

Interrater reliability of eight teacher rating scales designed to assess characteristics of attention-deficit hyperactivity disorder was investigated. Coteachers of 46 students completed the rating scales. The students, ages 8–17, were designated as having a Serious Emotional Disturbance. The resulting interrater reliability correlation coefficients ranged from .62 to .87. The percentage of variance shared between raters ranged from a low of 38.4% (the ACTeRS Oppositional factor and the CBCL-TRF Attention Problems factor) to 75.7% (ADHD Rating Scale). The percent of shared variance was higher for younger children. Kappa scores evaluating rater agreement were highest at the two standard deviations above the mean cutoff. The reliability coefficients were consistent with those reported in prior research.

A psychometric examination of the multidimensional perfectionism scale

The Multidimensional Perfectionism Scale (MPS), developed by Frost, Marten, Lahart, and Rosenblate (1990), was constructed using an all female sample at an elite university. This study examined the psychometric properties of the instrument using a more typical sample (n=278) of college students from a large state university and a small liberal arts college, both located in the South. Significant differences were found on the overall MPS score as well as six of the seven subscales between this sample and that of Frostet al. No gender differences were found for any of the MPS scores. Internal reliability was found to be .88 for the total score, with subtests ranging from .57 to .95. Interscore correlations were relatively consistent with the Frostet al. sample except for a negative correlation between the PS subscale and the total score. There was a strong confirmation of the underlying factor structure reported by Frostet al. The overall impression was that the MPS is a psychometrically sound instrument of potential value in studying the construct of perfectionism.     

A latent-trait based reliability estimate and upper bound

An estimate and an upper-bound estimate for the reliability of a test composed of binary items is derived from the multidimensional latent trait theory proposed by Bock and Aitkin (1981). The estimate derived here is similar to internal consistency estimates (such as coefficient alpha) in that it is a function of the correlations among test items; however, it is not a lowerbound estimate as are all other similar methods.An upper bound to reliability that is less than unity does not exist in the context of classical test theory. The richer theoretical background provided by Bock and Aitkin's latent trait model has allowed the development of an index (called here) that is always greater-than or equal-to the reliability coefficient for a test (and is less-than or equal-to one). The upper bound estimate of reliability has practical uses—one of which makes use of the greatest lower bound.     

A decision tree approach to selecting an appropriate observation reliability index

Based on the conceptual framework outlined by Cone (1986) and Suen (1988), a practical decision tree is developed as an aid for the selection of observational reliability indices.     

AN INSTITUTIONAL STAFF TRAINING AND SELF-MANAGEMENT PROGRAM FOR DEVELOPING MULTIPLE SELF-CARE SKILLS IN SEVERELY/PROFOUNDLY RETARDED INDIVIDUALS

Although considerable attention has been given to the development of institutional staff training and management programs, the generalized effects of such programs on staff and resident behavior have seldom been examined. This study evaluated a program for teaching institutional staff behavioral training and self-management skills during self-care teaching sessions with severely and profoundly retarded residents. Following baseline observations in three self-care situations (toothbrushing, haircombing, handwashing), four direct care staff were sequentially taught to use verbal instruction, physical guidance, and contingent reinforcement in the toothbrushing program. During maintenance, staff were simultaneously taught to record, graph, and evaluate resident and their own behavior in the toothbrushing sessions. Staff were taught use of the training and self-management skills through a sequence of written instructions, videotaped and live modeling, rehearsal, and videotaped feedback. Observer presence and experimenter supervision were gradually decreased during the maintenance condition. Results indicated that during training and maintenance staff: (a) learned to use the training skills appropriately and consistently in the example situation (toothbrushing); (b) applied the skills in the generalization situations (haircombing and handwashing); and thereafter (c) maintained consistent and appropriate use of the skills with infrequent supervision. In addition, important changes in retarded residents' independent self-care responding occurred as staff training skills developed. Results are discussed in terms of their implication for future research and continued development of effective staff training and management programs.     

A comparison of the accuracy and reactivity of methods of monitoring male sexual behavior

Two self-report methods of monitoring male sexuality have been compared—an ongoing method in the form of a diary card and one eliciting retrospective reports in the form of a monthly sexuality interview. Male volunteers were assigned at random to three testing conditions: (a) diary card and monthly interview for 3 months (N=29); (b) three monthly interviews (N=18); and (c) pre- and postinterview only, separated by 2 months (N=21). The correspondence among frequency reports, quality ratings, and number of sexual problems as obtained in diary card and interview measures was examined for respondents in the first condition, revealing that coital frequency and quality ratings were generally quite similar in the two modes of assessment. Interview responses for all subjects were examined for the existence of differential reactive effects according to the frequency of the assessment regimen. No differences emerged among conditions, although a trend for all groups over time was identified. Implications of the results are considered for clinical trials monitoring the effects of new contraceptive methods on sexual functioning.This study was supported by the World Health Organization's Special Programme of Research Development and Research Training in Human Reproduction (Project Nos. 76297 and 79003) and was conducted at King's College Hospital, London.     

Shaping data collection congruent with experimental hypotheses

The influence of instructions and feedback from an experimenter on observational recordings of disruptive behavior was evaluated. Four subject-observers recorded four categories of disruptive behavior from videotapes of children in a classroom setting. Two sets of videotapes, labelled "baseline" and "treatment", were matched for rates of disruptive behavior in each category. The observers were told that two target behaviors were expected to decrease and the other two control behaviors were not expected to change during the treatment condition. During observational recording of treatment videotapes, the observers were given positive feedback when they reported decreases in the two target behaviors, and negative feedback when they reported either to change or increases in the two control behaviors. The target behaviors were recorded less frequently by observers, while recordings of control behaviors were unaffected during the treatment phase. These results suggest that contingent feedback to observers should be avoided as a possible source of bias in behavioral recordings.     

A k-sample significance test for independent alpha coefficients

The earlier two-sample procedure of Feldt [1969] for comparing independent alpha reliability coefficients is extended to the case ofK 2 independent samples. Details of a normalization of the statistic under consideration are presented, leading to computational procedures for the overallK-group significance test and accompanying multiple comparisons. Results based on computer simulation methods are presented, demonstrating that the procedures control Type I error adequately. The results of a power comparison of the case ofK=2 with Feldt's [1969]F test are also presented. The differences in power were negligible. Some final observations, along with suggestions for further research, are noted.The authors gratefully acknowledge the assistance of Michael E. Masson, in the computations performed, and of Leonard S. Feldt, in suggesting the data generation procedures used in the study.
