This article provides a selected review of several contemporary communication intervention programs for people with developmental disabilities and severe communication impairment. Consideration of the extent and negative effects of severe communication impairment indicates the need for systematic intervention focused on teaching functional communication skills. Behaviour analysis procedures have demonstrated effectiveness for teaching functional communication skills. The major features of several behaviourally oriented communication intervention programs are reviewed. It is concluded that these programs have a sound empirical basis and demonstrated effectiveness for teaching functional communication skills to learners with developmental disabilities and severe communication impairment.

The following review paper describes the outcomes of data-based behavioural intervention strategies for the defining characteristics of autistic disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994). The results of relevant evaluations of behaviour analytic procedures are reviewed for each of the four potential areas of difficulty under each of the main criteria for autistic disorder, which are: (a) impairment in social interaction, (b) impairment in communication, and (c) restrictive, repetitive, and stereotyped patterns of behaviour, interests, and activities (DSM-IV). The current areas of research activity as well as those domains that have received comparatively little attention by behavioural researchers are identified, and suggestions for future research are discussed.

The study examined associations reported by carers between problem behaviour of 92 adults with intellectual disability and 169 antecedent events, which were either environmental situations or prior behaviours of the client. Factor analyses were used to identify groupings of antecedents, providing a basis for constructing 19 sets of antecedents of problem behaviours. Assessments were made of the psychometric properties of these sets of items or scales. Of the 19 scales, 18 were associated with an increased likelihood of problem behaviour, showing that carers reported that the problem behaviours of this sample occurred in a wide range of defined situations. The preliminary analysis suggests that the scales may be useful for inquiring more systematically about antecedents, for developing descriptions of situations where problems occur, and for identifying situations that warrant further analysis in individual cases.

A structured diary was used to collect information about the informal peer interactions of 536 children in their final year at nine primary schools. Measures of self-concept, social avoidance, and popularity were also taken. Initially, seven different scores were derived from the information contained in the diary to produce the Adolescent Social Interaction Profile (ASIP). Previous research with the ASIP subsequently identified three factors labelled scale, scope, and enjoyment of peer interactions, that were separate from a fourth generic self-concept factor derived from self-report questionnaires. Inspection of the factor scores for 19 children with full data sets who received the fewest peer nominations showed considerable heterogeneity, with only 1 child scoring low on more than two of the four factors. More expedient composite scores were then derived that reflected the factor loadings for the two complex ASIP scores labelled scale and scope. The utility of these scores for identifying and monitoring specific aspects of peer interaction difficulties is discussed.

The employment of untrained paraprofessionals to support children with disabilities in educational settings is not uncommon. Although urgently needed, research on effective methods of increasing the skills of these paraprofessionals is scarce. This study, which was conducted over 3 academic years, assessed the effectiveness of incorporating naturalistic prompting strategies by paraprofessionals for increasing target communicative behaviours of students with severe spastic quadriplegic cerebral palsy. A concurrent multiple-baseline design replicated across 3 paraprofessionals was used to determine the effectiveness of verbal and written feedback regarding their attainment of self-selected goals for prompting target communicative behaviours. The results indicate that, after the introduction of the intervention, the prompting behaviours of all paraprofessionals increased, as did the target behaviours of all students. Increases maintained 5 months after intervention for all students observed and for 2 of the 3 paraprofessionals observed. The implications of designing a program to include specific performance feedback and active involvement by staff are discussed.
