Treatment efficacy research: a window into genetic and neurodevelopmental correlates of developmental disabilities

This issue of MRDD research reviews is dedicated to treatment efficacy research. The treatment of MRDD conditions has long been a central question, but the clinical science of treatment efficacy has not yet been systematically applied to many MRDD typologies. The purpose of this paper is to provide an overview of this special issue and to provide a rationale for including treatment efficacy research as a tool for studying selected neurological development and genetic correlates of MRDD. Existing treatment efficacy paradigms should be applied systematically to relevant populations (and theoretical questions) and new, objectively tested paradigms should be developed in order to integrate ongoing discovery in MRDD.     

Understanding the role and function of maternal touch in children with neurodevelopmental disabilities

During the first years of life, maternal touch can serve different functions including facilitation of child’s gaze orientation to faces which is a key precursor for social attention. Although children with neurodevelopmental disability (ND) may have reduced social skills, the role of maternal touch in contributing to gaze orientation to maternal face has not been explored in previous research. In the present study, we investigate the functions of maternal touch in dyads of mothers and children with ND, compared to dyads of children with typical development (TD). Micro-analytic 2-s coding of maternal touch (i.e., affectionate, playful, facilitating, holding, no touch) and children’s gaze orientation (i.e., mother-oriented, object-oriented, non-oriented) occurred during 5-minute interactions between mothers and their 12-to-24-month-old ND and TD children. Dyads were paired for children chronological age and sex. Mothers of children with ND used more touch – especially facilitating and holding types –, compared to mothers of TD peers. Children with ND exhibited more non-orientated gaze compared to TD counterparts. Playful touch associated with increased mother-oriented gaze in children with ND, whereas affectionate and holding touch associated with greater mother-oriented gaze in TD children. Findings suggest that specific types of touch support children’s attention to social partners.     

Organizational change: initial results in a health care setting

An applied study was conducted in a federal health care facility to assess change in organizational climate variables over a 7-yr. period. Using the Survey of Organizations--2000, preliminary results show improvements on five climate indicators from Time 1 to Time 2 of the survey. Potential explanations for the positive changes are provided.     

Functional analysis and intervention of perseverative speech in students with high-functioning autism and related neurodevelopmental disabilities

Although perseverative speech is a common characteristic of individuals with high-functioning neurodevelopmental disabilities, little is known about the operant functions of these verbalizations. We conducted analogue functional analyses of perseverative speech for 2 students using reinforcement contingencies that included alone, attention, control, escape, and tangible conditions. Results showed the following patterns: attention only (Charlotte) or multiply determined including an attention function (Paul). We then tested an intervention for perseverative speech maintained by social positive reinforcement that included differential reinforcement of alternative behavior and extinction of perseverative speech for 1 participant. The intervention reduced perseverative speech, but did not increase appropriate speech until we added a prompting component. We then replicated this three-component intervention with Paul. The results showed moderate to high decreases in levels of perseverative speech and increased appropriate verbalizations in both cases. The results systematically replicated the interventions of previous studies by adding a prompting component to the intervention.     

Translational behavior analysis: from laboratory science in stimulus control to intervention with persons with neurodevelopmental disabilities

Throughout its history, laboratory research in the experimental analysis of behavior has been successful in elucidating and clarifying basic learning principles and processes in both humans and nonhumans. In parallel, applied behavior analysis has shown how fundamental behavior-analytic principles and procedures can be employed to promote desirable forms of behavior and to prevent or ameliorate undesirable forms in clinical, educational, and other settings. Less obviously, there has also emerged a small but identifiable bridging field that can potentially connect and inform both basic and applied behavior analysis. Although such translational behavior analysis uses laboratory methodologies, research targets are selected largely for their value in ultimate application to improve the human condition. I will discuss the distinction of translational behavior analysis from basic and applied behavior analysis and consider the potential contribution that translational research can make in the development of the science of behavior.     

Life space mapping: Preliminary results from the development of a new method for investigating counselling outcomes

Counselling outcomes are often measured in terms of standardised questionnaires. Though efficient for large numbers of participants, this method cannot capture the unique and subtle ‘shifts’ that clients often report when qualitative methods are utilised. Further, such questionnaires usually focus on the individual, missing the wider social implications of therapy. This paper presents the preliminary findings from a study that utilises the client's own perceptions of changes in their “Life Space” to establish the significance of their change process. These results are compared and contrasted with a standard outcome questionnaire and the participant's experiences of using the two methods are explored.     

The development and initial validation of the Multicultural Environmental Inventory: a preliminary investigation

This article describes the development and initial validation of the Multicultural Environmental Inventory (MEI). The MEI is an instrument designed to measure an individual's perceptions about the degree to which graduate counseling programs address multicultural issues within curriculum, supervision, climate, and research. This investigation was conducted using the data from 208 students and faculty from counseling psychology graduate programs across the United States approved by the American Psychological Association. By using techniques of exploratory factor analysis, a 4-factor solution was determined to account for the relationships among the items on the MEI. The instrument was modified from 53 to 27 items on the basis of the items' effectiveness in measuring the underlying constructs of interest, and internal consistency information is provided on the final revised instrument (MEI-R). The factors underlying the MEI-R are discussed within the context of a multicultural environment in graduate counseling programs, and directions for future research are considered.     

Asymmetry and performance: toward a neurodevelopmental theory

Hemispheric asymmetry implies the existence of developmental influences that affect one hemisphere more than the other. However, those influences are poorly understood. One simple view is that asymmetry may exist because of a relationship between a mental process' degree of lateralization and how well it functions. Data scaling issues have largely prevented such investigations, but it is shown that scaling effects are minimized after correction for ceiling and floor effects. After correction, lateralization-performance correlations are pervasive. However, while some correlations are positive, others are negative, with the direction depending on the underlying lateralized process. Two hypotheses are proposed that can account for these relationships by pointing either to individual differences in maturation of the corpus callosum or to developmental limits encountered at different ages of childhood. Their investigation should contribute toward a neurodevelopmental theory of hemispheric asymmetry.     

Toward a three-dimensional conceptualization of performance anxiety: Rationale and initial measurement development

ObjectivesAn integrated three-dimensional model of performance anxiety was constructed to offer an alternative conceptualization that may contribute to understanding of the complex anxiety–performance relationship. In particular, the adaptive potential (producing positive effects) of anxiety was acknowledged explicitly by including a regulatory dimension. This model is characterized by five subcomponents, with worry and self-focused attention representing cognitive anxiety, autonomous hyperactivity and somatic tension representing physiological anxiety, and perceived control representing the regulatory dimension of anxiety. The overview of the conceptual framework and the underlying rationale are presented.DesignAs a necessary first step towards model testing, an initial measure was developed and the factorial validity of the model was investigated.MethodConfirmatory factor analysis was used in two independent samples (N = 286, 327) in a wide context of sports performance.ResultsA 25-item measure of performance anxiety was established. Findings of CFA revealed support for a three-dimensional first-order model.ConclusionsAlthough the present model of performance anxiety was best presented as a three-dimensional first-order structure, the integrity of the conceptual framework is considered intact as such a factor structure distinctly reflects the three major processes (i.e., cognitive, physiological and regulatory) that are proposed to be activated in the anxiety dynamics from a broad cognitive perspective.     

Research validity scales for the NEO-PI-R: development and initial validation

The purpose of this investigation was to develop a set of research validity scales for use with the NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992b). In study 1 we used the existing NEO-PI-R item pool to select items for three validity scales: positive presentation management, negative presentation management, and inconsistency. Several iterative item and scale analyses were conducted, using multiple criteria for item selection. These analyses resulted in 10-item scales. In Study 2, the internal consistency, interscale relationships, and normative characteristics were examined in a separate sample of working adults. In Study 3, the validity of the scales was examined by contrasting five sets of NEO-PI-R protocols: from a separate sample of working adults, from a sample of 100 NEO-PI-R protocols with randomly produced responses, and from three samples of undergraduates completing the NEO-PI-R under different instructional sets. Analyses revealed that both the research validity scales and the NEO-PI-R domain scales were sensitive to group differences. issues relating to the appropriate use of the scales are discussed.     

Sensitivity to interpersonal treatment in the workplace: Scale development and initial validation

The authors designed the sensitivity to interpersonal treatment (SIT) scale to assess how strongly individuals react to the interpersonal interactions in their workplaces. Questionnaire responses from 563 working undergraduates and 446 working adults provided data for this study. Details on the development of the new scale are provided along with initial evidence for its validity. Results indicated that the SIT is an internally consistent scale composed of two factors: self‐treatment and other‐treatment. Suggestions for future research that will develop a further understanding of SIT in the workplace are discussed.     

Public policy and employment of people with disabilities: exploring new paradigms

A "sea change" in public attitudes, legislation, and political power at the end of the 20th century in the United States has helped set the stage in the early 21st century for the entry of people with disabilities into the labor force. Major pieces of federal legislation have altered national policy with the intention of maximizing the work force participation of people with disabilities. At the same time, a new theoretical paradigm of disability has emerged, which emphasizes community inclusion, accommodation, and protection of civil rights. This "New Paradigm" of disability can be applied in concert with rigorous behavioral science methodologies to shed light on the outcomes of recent federal policy changes regarding the labor force participation of people with disabilities. In so doing, social science can be used in more meaningful ways to understand both the intended and unintended consequences of federal policy.     

The physical self-attribute questionnaire: development and initial validation

The Physical Self-attribute Questionnaire was developed for use in conjunction with the Physical Self-perception Profile to model cognitive facets of perceived competence, certainty, importance, and discrepancy from ideal to each of the physical subdomains measured by the latter (Strength, Attractive Body, Condition, and Sport). To this end, two studies were conducted. Study 1 examined the factor structure, test-retest reliability, and validity of the questionnaire in a sample of 154 (28 men, 126 women) undergraduate health students. Reliability and validity were acceptable, and confirmatory factor analysis indicated good fit for a four-factor solution. In Study 2, the reliability, validity, and factor structure was again confirmed in a sample of 120 (83 men, 37 women) undergraduate students recruited from exercise classes. Results of these two studies suggest that the Physical Self-attribute Questionnaire is a viable tool to measure the underlying cognitive facets of subdomain-specific physical self-esteem.     

Predictors of early person reference development: Maternal language input,attachment and neurodevelopmental markers

In a longitudinal natural language development study in Germany, the acquisition of verbal symbols for present persons, absent persons, inanimate things and the mother–toddler dyad was investigated. Following the notion that verbal referent use is more developed in ostensive contexts, symbolic play situations were coded for verbal person reference by means of noun and pronoun use. Depending on attachment classifications at twelve months of age, effects of attachment classification and maternal language input were studied up to 36 months in four time points. Hierarchical regression analyses revealed that, except for mother absence, maternal verbal referent input rates at 17 and 36 months were stronger predictors for all referent types than any of the attachment organizations, or any other social or biological predictor variable. Attachment effects accounted for up to 9.8% of unique variance proportions in the person reference variables. Perinatal and familial measures predicted person references dependent on reference type. The results of this investigation indicate that mother-reference, self-reference and thing-reference develop in similar quantities measured from the 17-month time point, but are dependent of attachment quality.     

Perception without attention: results of a new method.

Having found by the use of a new method for examining perception without attention that grouping and texture segregation do not seem to occur (see Mack, Tang, Tuma, Kahn, & Rock (1992) Cognitive Psychology, 24, we go on to ask what is perceived without attention using this new method. Our subjects receive only one inattention trial in a sequence of trials involving a visual distraction task. In addition to the distraction task in the inattention trial, subjects received a stimulus of which they had no prior knowledge or expectation and were questioned or tested directly afterward for their perception of that stimulus. Two subsequent trials containing test stimuli serve as within-subject controls. The results of a series of experiments indicate that the presence of one or more stimulus objects and their locations are preattentively perceived, as is their color, but shape is not. Because individual items are detected without attention, we conclude that perceptual organization is initially based on a principle in which connected regions of uniform stimulation are inferred to be discrete units (the principle of uniform connectedness). One striking, unexpected finding is that without attention many subjects have no awareness at all of the stimulus object, an effect we call inattentional blindness.     

Healthcare provider cultural competency: development and initial validation of a patient report measure.

OBJECTIVE: Health researchers have proposed that provider cultural competency may contribute to health disparities. Yet, this belief continues to lack empirical support, and this is due in part to measurement issues that have plagued the cultural competency construct. In the present research, we report on the development of a theoretically grounded, generally applicable, and patient report measure of provider cultural competency. DESIGN: Samples of predominantly African American patients (N=310) were recruited from three urban medical clinics to complete a survey about their relationship with their physician. MAIN OUTCOME MEASURES: We examined the factor structure, validity and other psychometric characteristics of a newly proposed patient report measure of provider cultural competency. RESULTS: Psychometric analyses supported a tripartite model of cultural competency that was comprised of patient judgments of their physician's cultural knowledge, awareness, and skill. In addition, this result was replicated across multiple clinical contexts, while also demonstrating convergent and incremental validity when correlated with measures of trust, satisfaction and discrimination. CONCLUSION: This newly proposed measure addresses prior limitations in cultural competency measurement and may enhance future research by providing a standardized tool for use in multiple clinical and cultural contexts.     

The Body Image Concern Inventory: validation in a multiethnic sample and initial development of a Spanish language version

Dysmorphic appearance concern encompasses preoccupation with a perceived appearance defect, defect checking and camouflaging, and social avoidance. The current study sought to evaluate the internal consistency, factor structure, and convergent validity of a measure of dysmorphic appearance concern, the Body Image Concern Inventory, as well as evaluate the psychometric properties of a Spanish version of the instrument. Women recruited as part of a reproductive clinic-based clinical trial completed the BICI and other self-report measures of distress. A total of 1043 women completed the measures in English (M=29 years, range=18-55 years) and 573 women completed the measures in Spanish (M=32 years, range=18-55 years). Both the English and Spanish BICI were internally consistent and correlated moderately with measures of current psychological distress (STAI-S, CES-D). Confirmatory factor analyses replicated the measure's proposed factor structure. Applications of the BICI for future research are discussed.     

Proactive vitality management in the work context: development and validation of a new instrument

In the present research, we use proactivity literature and studies on energy at work to argue that individuals may proactively manage their vitality (i.e., physical and mental energy) to promote optimal functioning at work. We develop and validate a scale to measure proactive vitality management (PVM), and explore the nomological network. We conducted a five-day diary study (N = 133; 521 days), a survey study (N = 813) and a cross-sectional study measuring daily PVM (N = 246) among working individuals from various occupational sectors. The results show that PVM can be reliably measured with eight items that load on one overall factor, both on general and daily level. Furthermore, daily PVM was moderately but positively related to the use of work-related strategies and micro-breaks. Moreover, PVM related positively to relevant personal characteristics (i.e., proactive personality and self-insight) and showed moderate but positive relationships with job crafting and relaxation (convergent validity). PVM was unrelated to psychological detachment and decreasing hindering demands (discriminant validity). Finally, PVM was positively related to well-being, in-role work performance, creative work performance and performance on the Remote Associates Test (criterion validity). We conclude that employees may promote their own work performance through the use of PVM.
