Measures of life stress and social support specific to an Asian student population

We designed two new measures—the Index of Life Stress (ILS) and the Index of Social Support (ISS)—to assist in the prediction of cultural adjustment for an Asian international student population. In the present study, these two measures were administered to 101 Asian international students. Stability estimates over 1 month were high: .97 for the ILS and .81 for the ISS. Construct validity, assessed via factor analyses, and concurrent validity, assessed via regression analyses to criteria of depression, hopelessness, and suicide ideation were satisfactory. Incremental validity for these two measures relative to extant measures of life stress and social support were computed. Results from these analyses indicated that these two measures added incrementally to the prediction of adjustment beyond that offered by existing measures.     

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.     

LONG-TERM FOLLOW-UP OF ECHOLALIA AND QUESTION ANSWERING

A long-term follow-up of echolalia and correct question answering was conducted for 6 subjects from three previously published studies. The follow-up periods ranged from 26 to 57 months. In a training site follow-up, subjects were exposed to baseline/posttraining conditions in which the original trainer and/or a novel person(s) presented trained and untrained questions. Four subjects displayed echolalia below baseline levels, and another did so in some assessments. Overall, echolalia was lower than in baseline in 80.6% of the follow-ups. Five subjects displayed correct responding above baseline levels. No clear differences were noted in correct responding or echolalia between the trainer and novel-person presentations or between trained and untrained questions. In a follow-up in a natural environment conducted by a novel person, lower than baseline levels of echolalia were displayed by 3 subjects; 2 subjects displayed lower than baseline levels in some assessments. Two subjects consistently displayed correct responding above baseline, and 3 did so occasionally. Issues related to the study of maintenance are discussed.     

Utilization and predicted trends of behavioral inventories

Published articles (N=1703) during the period 1975 to 1982 in three behavioral journals (Behavior Therapy, Journal of Behavior Therapy and Experimental Psychiatry, andJournal of Applied Behavior Analysis) were reviewed for the utilization of preintervention and categories of behavioral inventories. Results revealed that (a) the three forms of the Fear Survey Schedule (FSS) and the Social Avoidance and Distress Scale (SADS) were the most utilized traditional behavioral measures, (b) new self-developed inventories were reported with significantly (p<.05) different frequencies across the three journals, (c) numerous published inventories beyond the traditional FSS and SADS were reported, and (d) an expanded use of IQ measures in preintervention behavioral assessment was also found. Trends regarding the nature of behavioral inventories among the three journals and a discussion on advances in behavioral assessments are presented.     

Comparability of peer-assessment measures: A multitrait-multimethod and selection analytic approach

This research attempted to assess the relationship among the Pupil Evaluation Inventory (PEI), sociometric nominations, and sociometric ratings in terms of (1) a multitrait-multimethod analysis, (2) selection agreement indices of extreme individuals, and (3) stability over an 8-week period. Subjects were members of four second-grade classrooms at a regional school serving a diverse population of children. While stability estimates for measures were adequate and evidence for convergent validity was reasonably good, evidence for divergent validity was weaker. Selection agreement analyses yielded highly variable results, indicating that different samples of children tend to be selected by different instruments despite the similarity in dimensions being tapped. Methodological and theoretical implications of these findings are discussed.This work was based on the first author's M.S. thesis under the direction of the second author.     

The relationship between differential stimulus relatedness and implicit measure effect sizes

Implicit measures have been hypothesized to allow researchers to ascertain the existence and strength of relations between stimuli, often in the context of research on attitudes. However, little controlled behavioral research has focused on whether stimulus relations, and the degree of relatedness within such relations, are indexed by implicit measures. The current study examined this issue using a behavior‐analytic implicit‐style stimulus relation indexing procedure known as the Function Acquisition Speed Test (FAST). Using a matching‐to‐sample (MTS) procedure to train stimulus equivalence relations between nonsense syllables, the number of iterations of the procedure was varied across groups of participants, hence controlling stimulus relatedness in the resulting equivalence relations. Following final exposure to the MTS procedure, participants completed a FAST. Another group of participants was exposed to a FAST procedure with word pairs of known relatedness. Results showed that increasing relatedness resulted in a linear increase in FAST effect size. These results provide the first direct empirical support for a key process‐level assumption of the implicit literature, and offer a behavior‐analytic paradigm within which to understand these effects. These results also suggest that the FAST may be a viable procedure for the quantification of emergent stimulus relations in stimulus equivalence training.     

Crewmember performance before, during, and after spaceflight

The development of technologies for monitoring the welfare of crewmembers is a critical requirement for extended spaceflight. Behavior analytic methodologies provide a framework for studying the performance of individuals and groups, and brief computerized tests have been used successfully to examine the impairing effects of sleep, drug, and nutrition manipulations on human behavior. The purpose of the present study was to evaluate the feasibility and sensitivity of repeated performance testing during spaceflight. Four National Aeronautics and Space Administration crewmembers were trained to complete computerized questionnaires and performance tasks at repeated regular intervals before and after a 10-day shuttle mission and at times that interfered minimally with other mission activities during spaceflight. Two types of performance, Digit-Symbol Substitution trial completion rates and response times during the most complex Number Recognition trials, were altered slightly during spaceflight. All other dimensions of the performance tasks remained essentially unchanged over the course of the study. Verbal ratings of Fatigue increased slightly during spaceflight and decreased during the postflight test sessions. Arousal ratings increased during spaceflight and decreased postflight. No other consistent changes in rating-scale measures were observed over the course of the study. Crewmembers completed all mission requirements in an efficient manner with no indication of clinically significant behavioral impairment during the 10-day spaceflight. These results support the feasibility and utility of computerized task performances and questionnaire rating scales for repeated measurement of behavior during spaceflight.     

The Program Environment Scale: Assessing Client Perceptions of Community-Based Programs for the Severely Mentally Ill

The Program Environment Scale (PES) was developed for use with clients of community-based programs for the severely mentally ill. It is intended to fill the gap in available tools for assessing clients' perceptions of program functioning as it affects their quality of life in a program. Formal pretests were conducted with 121 clients at 12 randomly selected programs near Washington, DC. The final field test used a revised form (29 domains; 129 items) with 221 clients in 22 programs selected randomly throughout the U.S., including Clubhouse, day treatment, psychosocial rehabilitation, and social club programs. Twenty-three subscales met at least five of eight psychometric criteria for internal consistency and discriminant validity. A 24th subscale was retained because of its substantive importance. Successful subscales cover program atmosphere and interactions (program cares about me, energy level, friendliness, openness, staff-client and client-client respect, reasonable rules, availability of positive physical contact, protection from bad touch, staff investment in their jobs, and confidentiality), client empowerment/staff-client equality (program and treatment empowerment, egalitarian space use), and service components (support for paid work, work importance, emergency access, family activities, housing, public benefits, community activities, medications, substance abuse, and continuity). Subscale validity is indicated by associations of specific service offerings with scores on scales measuring client perceptions of those services, and by an ability to differentiate among program models (i.e., Clubhouses, day treatment programs, and psychosocial rehabilitation programs look different from each other). Subscale scores were not influenced by client characteristics (gender, race, age, diagnosis, number of hospitalizations, length of time in program). The final scale has 97 items and takes about 25 minutes to complete. The PES succeeds in measuring different aspects of programs as clients perceive them. In the programs we visited, directors felt the PES covers the important things they want to know about how clients perceive their program. The PES should become a useful tool both for researchers interested in how client responses to programs may influence their therapeutic outcomes, and for practitioners interested in improving their clients' program experiences and/or increasing convergence of staff and client views of their program.     

Neuropsychological Evaluation of Everyday Memory

The evaluation of everyday memory (EM) was reviewed and reconceptualized. EM has established new objectives of study and the development of new methods to reach these objectives . At the basic level, this approach has already produced important discoveries and the development of new principles about memory and functioning. At the clinical level, this new area of investigation has resulted in evaluating deficits of EM, which is defined as what daily life functions remain impaired after a deficit pathology has occurred. A type of evaluation has evolved that is oriented toward treatment and extremely useful in designing rehabilitation programs for individuals with alterations in memory.
