Enhancing the Quality of Interaction Between Deafblind Children and Their Educators

This study examined the effects of an educator-oriented intervention program to improve the quality of the interactions between deafblind children and their professional educators. Four deafblind children, aged 6–9 years, and their 14 educators took part in the experiment. The educators were trained to respond more adequately to a selected set of appropriate and inappropriate interactive child behaviors. In three of the four children, the mean percentage appropriate interactive behaviors increased with intervention (with a gain of 47.2% across the four children). The number of inappropriate child behaviors also decreased. These positive effects manifested themselves across the various intervention situations and were accompanied by an increase in the mean percentage appropriate responses on the part of the educators. Results suggest that the improvement in the childrens interactive competence was indeed caused by improved educator behavior.

Effects of video-feedback interaction training for professional caregivers of children and adults with visual and intellectual disabilities.

BACKGROUND Individuals in group homes may experience poor quality of social interaction with their professional caregivers, limiting their quality of life. The video-based Contact programme may help caregivers to improve their interaction with clients. METHOD Seventy-two caregivers of 12 individuals with visual and intellectual disabilities received a training programme and four individual video-feedback sessions. Quality of interaction was independently measured in an AB-design across subjects with two baseline and three intervention observations, using a time sampling coding system for interactive behaviour as well as a rating for affective mutuality. RESULTS From baseline to intervention, significant increases were found for the frequency with which caregivers confirmed the signals of clients, for the proportion of initiatives taken by clients that were responded to by the caregivers, and the affective mutuality as a quality of the interaction. No significant increase in client responsiveness was observed. Caregivers evaluated the intervention as useful and feasible. CONCLUSIONS The start of the Contact programme coincided with improved quality of interaction between professional caregivers and clients with visual and intellectual disabilities in group homes. Further research is necessary regarding the generalisability, long-term effects and effects on quality of life.

Describing dialogue between persons with profound intellectual and multiple disabilities and direct support staff using the scale for dialogical meaning making

BACKGROUND The dialogical approach of meaning making forms a rich and renewing theoretical perspective to study communication between presymbolic communicators and their interaction partners. The aim of this study is to investigate whether an observation scale based on the dialogical theory, the Scale for Dialogical Meaning Making (S-DMM), has potential to describe these communicative interactions. METHODS Eighteen videotaped observations of persons with profound intellectual and multiple disabilities and their support staff were coded using the S-DMM and a consensus-rating procedure. RESULTS Sufficient inter-rater agreement and an acceptable range in scores confirm the usefulness of the S-DMM. Strong sub-scale intercorrelations were identified. The quantitative scores and the qualitative arguments supporting the ratings, demonstrate how the S-DMM aids to significantly describe staff-client dialogue. CONCLUSIONS Using the S-DMM to describe dialogue with persons with profound intellectual and multiple disabilities appears to be promising. The value of the S-DMM and its consensus-rating procedure are reflected upon and discussed with regard to implications for research and practice.

Stimulating Intersubjective Communication in an Adult with Deafblindness : A Single-Case Experiment

Sensory disabilities may limit a persons development of intersubjectivity, that is, the awareness of self and other, which develops in conjunction with interpersonal communication. This study used intersubjectivity theory to test a new intervention called the High-Quality Communication (HQC) intervention for its effects on a young adult with congenital deafblindness and a developmental age of between 1.5 and 4 years. Three of his social partners were trained to support attunement and meaning making with him through education and video feedback. This study measured seven observation categories at three layers of intersubjective development during a baseline and two intervention phases: dyadic interaction, shared emotion, referential communication, meaning negotiation, shared meaning, declarative communication, and shared past experience. The participants use of conventional communication was included as an additional category. Effects were observed in all observation categories from the baseline to the intervention phases. Further study of the effectiveness of the HQC intervention is recommended to test whether effects generalize across people and settings.

Adaptive assessment of young children with visual impairment

The aim of this study was to assess the effect of adaptations for children with low vision of the Bayley Scales, a standardized developmental instrument widely used to assess development in young children. Low vision adaptations were made to the procedures, item instructions and play material of the Dutch version of the Bayley Scales of Infant Development — Second Edition (BSID-II), and the Original and Low Vision versions were administered to children with visual impairment over an interval of two weeks. Although quantitative analysis revealed no significant differences between the Original and Low Vision versions of the test in children’s scores, feedback from test administrators indicates that the Low Vision materials make the test easier to administer and more engaging for children.

Intervening on Affective Involvement and Expression of Emotions in an Adult With Congenital Deafblindness

This study examined the effects of a 20-week intervention to foster affective involvement during interaction and communication between an adult with congenital deafblindness (CDB) and his caregivers in a group home and a daytime activities center. Using a single-subject design, we examined whether the intervention increased affective involvement between the participant and his caregivers, and whether the participant’s positive emotions increased and his negative emotions decreased. In both settings, an increase in affective involvement and very positive emotions coincided with the onset of the intervention, with the clearest effects in the daytime activities center. Negative emotions decreased in the daytime activities center. During follow-up, affective involvement decreased in both settings but remained above baseline. The caregivers indicated that it was easier to share positive emotions than negative emotions. This study demonstrates that it is possible to foster affective involvement with an adult with CDB, both during interaction and communication.

The Application of Dynamic Assessment in People Communicating at a Prelinguistic Level: A descriptive review of the literature

Many people with severe disabilities face difficulties communicating with their communication partners and rely primarily on prelinguistic communication. It is accepted that dynamic assessment can play an important role in improving communication and in measuring a person’s ability to learn new communicative skills. Less is known, however, about the application of dynamic assessment in the case of those who communicate at a prelinguistic level. The present article reviewed dynamic assessment procedures that addressed communication abilities in people communicating at a prelinguistic level and young children who communicate using speech, with the aim of identifying key elements of dynamic assessment for persons communicating at a prelinguistic level. The results indicated the need for the identification of contextual variables that support communicative competence, teaching communication partners new skills, and a procedure that is highly individualised. Further research on the validity and reliability of these dynamic assessments is strongly recommended.

Understanding the relationship between teacher behavior and motivation in students with acquired deafblindness

Because little is known about teacher-student relationships that involve students with acquired deafblindness, the authors performed a multiple case study with a multiple-method design to investigate the relationship between need-supportive teaching behaviors and student engagement. Using self-determination theory (Deci & Ryan, 2000), they analyzed video observations of interactions. It was found that teachers’ provision of structure, autonomy support, and involvement often cooccurs with higher levels of student engagement. Moreover, varying degrees of need support over time seem to result in varying levels of student engagement. Examples are provided of need-supportive teaching behaviors that can be used to foster the motivation of students with acquired deafblindness.

Communication between Children with Deafness, Blindness and Deafblindness and their Social Partners: An Intersubjective Developmental Perspective

Trevarthen’s theory of innate intersubjectivity is relevant to understanding communication problems in children with sensory disabilities. Trevarthen and Aitken used the term “intersubjectivity” to describe “the ability of humans to detect and change each other’s minds and behavior”. When children lack auditory and/or visual means of interaction, they may not be able to fully develop intersubjectivity, which impedes the development of more complex interpersonal communication. This article presents a review of 31 studies about intersubjectivity in children with sensory disabilities. The results indicate that the intersubjective development of children with sensory disabilities is often delayed. The studies also describe similar strategies for mediating intersubjectivity in children with sensory disabilities and in typical children, but say that specific adaptations may be needed. From an intersubjectivity perspective, symbolic communication delays in children with sensory disabilities may be improved through specific, purposeful forms of social interaction.

Intervening to improve teachers’ need-supportive behaviour using Self-Determination Theory: Its effects on teachers and on the motivation of students with deafblindness

Abstract Research on Self-Determination Theory has shown that teachers’ need-supportive behaviour is associated with student motivation and engagement. The purpose of this study is to examine the effectiveness of an intervention aimed at increasing the motivation of students with congenital and acquired deafblindness by enhancing teachers’ need-supportive behaviour. To assess the intervention effect, this study follows a multiple case-study design. Teacher questionnaires were administered and video observations of teacher–student interactions were made during pre-test, post-test and follow-up phases. The results showed that teachers provided involvement most, followed by structure and autonomy support. Teachers’ provision of structure and autonomy seems to improve most after the intervention. In general, teachers of students with congenital deafblindness showed larger intervention effects than teachers of students with acquired deafblindness. The results also provide indications that students’ levels of engagement improved after the intervention.
