An evaluation of hospital-based specialized staffed housing for people with seriously challenging behaviours.

Resident and staff activity was observed in two hospital-based staffed houses for adults with severe or profound mental handicap, and seriously challenging behaviours. The results indicated that: (1) staffing resources were inefficiently deployed, leading to low levels of support being provided to service users; (2) staff attention was inequitably distributed across users, individuals showing the highest levels of seriously challenging behaviours received disproportionately more staff attention; (3) users spent little of the time they were observed engaged in constructive activities. Comparisons with data collected previously on four of the users in institutional settings indicated that: (4) no overall changes occurred in either user participation in constructive activities or (5) duration of challenging behaviours; and (6) overall, more staff contact was provided in the specialized housing projects compared to previous institutional settings. The results are discussed in terms of the determinants of quality in residential provision for people with seriously challenging behaviour.

The prediction of change in repertory grids.

Several predictions relating to differential element and construct stability in repertory grids over time were investigated. Test-retest data indicated significantly greater construct stability for high intensity or 'constellatory' constructs over a seven-month period. Consistency of element ratings was also significantly greater for high intensity (constellatory) constructs, but only for certain elements. Evidence is also reported indicating that the dimension of cognitive complexity may also serve as a moderator of the above relationships.

'Preparedness' and the development of aversive associations.

The paper presents two studies investigating the role of the preparedness value of stimulus content in an aversive compound signal conditioning procedure. It was predicted that greater compound to component transfer would occur to 'potentially phobic' compared to 'neutral' stimulus components, and that responses to potentially phobic components would show a relatively greater resistance to extinction. Results from both studies failed to support these hypotheses thus questioning the generality of the previously demonstrated role of 'preparedness' in average associative processes.

Descriptive analysis of multiple response topographies of challenging behavior across two settings.

Time-based lag sequential analyses were conducted on 23 topographies of challenging behavior shown by five young people with severe mental retardation across two settings. Potential behavioural functions were identified for 21 of the 23 behaviors. Responses classes, including two or more distinct behaviors, were identified for four of the five participants. Two participants showed evidence of two functionally distinct response classes; for one person each response class included both self-injurious and stereotypic behaviors. For 9 of the 11 behaviors for which data were available, the hypothesised function of behaviors was consistent across settings. For one person, data suggested that the function of one self-injurious behavior was contextually determined. Cross-validation with brief experimental analyses resulted in agreement on the general behavioral function for 12 of the 14 instances in which both approaches positively identified a potential function for a behavior. Implications for future research and practice are discussed.

The quality and costs of residential services for adults with multiple disabilities: a comparative evaluation.

The costs and quality of four different service models for 40 adults with multiple disabilities were compared. The four service models were: specialised institution-based units; a specialised, campus-style, further education service; specialised community-based group homes; and "ordinary" community-based group homes. Some information was also available from five adults with multiple disabilities living in traditional institutions for people with mental retardation. On almost all measures of service outcome the specialised group-home model was the "preferred" service model, although this model was not associated with particularly high service costs. There was, however, considerable variation in quality within, as well as between, service models, with some residents in all service models experiencing levels of support and engagement similar to those found in traditional institutions. The results of the study are discussed in relation to notions of typical practice and normative standards. The implications of the findings are discussed.

A review of choice research with people with severe and profound developmental disabilities.

During the last 15-20 years, a significant amount of research has focused on the issue of choice among people affected by severe-profound developmental disabilities. Studies have been directed at (a) assessing the ability of those people to choose between different options and express preferences that could be used for reinforcement or occupational purposes, (b) building choice opportunities within those people's daily situations, and (c) evaluating the possible effects of choice making on those people's performance and behavior. This paper reviews the aforementioned studies and comments on the main findings and related questions.

The effectiveness of staff support: evaluating active support training using a conditional probability approach.

Active Support, a package of procedures which includes activity planning, support planning, and training on providing effective assistance, was introduced in five community residences serving 19 adults with severe mental retardation following a multiple baseline design. Real-time observational data were collected on the level of assistance residents received from staff and their engagement in activity. Active Support was shown in a companion paper (Jones et al., 1999) to increase the levels of assistance residents received and their engagement in activity. Increased assistance was particularly experienced by the behaviorally less able and the disparity in activity between the more and less able was reduced. In the analysis presented here, the effectiveness of assistance was evaluated before and after Active Support training by calculating the likelihood of engagement occurring given the occurrence of assistance. This likelihood was represented by the statistic, Yule's Q. Yule's Q significantly increased following Active Support training, an increase that was maintained at follow-up. The increased effectiveness of assistance was related to other research findings on the relationship between staff: resident interaction patterns and resident behavior.

Lifestyle related risk factors for poor health in residential settings for people with intellectual disabilities.

Little information is available on the prevalence and determinants of lifestyle related risk factors for poor health (obesity, poor diet, physical inactivity, smoking and alcohol abuse) among people with intellectual disabilities. This study reports the prevalence of these risk factors for 500 people with intellectual disabilities living in different forms of residential provision in the UK. Variables which predict the presence of these risk factors are also identified. While levels of smoking and alcohol abuse were low, the prevalence of poor diet, obesity in women and physical inactivity was high. Analyses of predictors of risk factors present a mixed pattern with regard to participant and service characteristics, with greater ability and less restrictive residential settings being associated with poor diet, smoking and obesity, but physical inactivity being associated with lower ability and more restrictive settings. It is argued that increasing levels of moderate or vigorous physical activity among people with intellectual disabilities would be the single most effective way of improving the health of people with intellectual disabilities.

The prevalence of challenging behaviors: a total population study.

A total population study was undertaken in two areas of England to identify the situation and characteristics of people reported to exhibit challenging behaviors. We found that: (1) challenging behaviors are shown by 10-15% of people with mental retardation who are in contact with educational, health or social care services for people with mental retardation; (2) the most common forms of challenging behaviors reported were 'other' behavior (shown by 9%-12% of all people screened), aggression (7%), destructive behavior (4%-5%) and self-injury (4%); (3) the majority of people identified showed two or more of these four general forms of challenging behavior; (4) approximately two-thirds of the people identified were boys/men; (5) close to two-thirds of the people identified were adolescents or young adults; (6) approximately 50% of the people identified as showing more demanding challenging behavior were living with their families; (7) people who showed more demanding challenging behavior were more likely to need greater levels of assistance in eating, dressing and washing, be incontinent and have more restricted expressive and receptive communication.

Predicting the persistence of severe self-injurious behavior.

Information was collected on 95 people with mental retardation who had been identified seven years previously as showing severe self-injurious behavior. At follow up 71% of participants were still showing self-injurious behavior of a severity which presented a management problem for care staff. The occurrence of specific topographies of self-injury was extremely stable among the group showing persistent self-injury. Finally, self-injury status at follow-up was predicted with 76% accuracy by a logistic regression model containing three variables: site of injury (higher persistence being shown by people exhibiting head directed self-injury); reported (greater) stability of self-injury when first identified; and (younger) age.

The adaptive behavior scale-residential and community (part I): towards the development of a short form.

A potential 24-item short form (SABS) of the 73-item Adaptive Behavior Scale-Residential and Community (Part I) (ABS-RC2; Nihira et al., 1993a, b) was developed, based on data from two diverse UK samples of adults with intellectual disabilities living in residential services (n = 560 and 254). SABS factor and total scores showed good internal reliability in both samples (alpha 0.89-0.98), and were highly correlated with their full ABS-RC2 Part I equivalents (r = 0.97-0.99). Regression equations were calculated for SABS factor and total scores against their full ABS-RC2 Part I equivalents. Levels of agreement between predicted quartile scores (derived from the regression equations) and actual full ABS-RC2 Part I quartile scores were high (kappa 0.75-0.89; percentage agreement 82%-92%). It is concluded that the SABS is a potentially useful research tool, although further work is clearly needed to establish the reliability and cross-cultural validity of the instrument.

Environmental opportunities and supports for exercising self-determination in community-based residential settings.

Information was collected on the environmental opportunities for exercising self-determination among 281 adults with mental retardation receiving community-based residential supports. The results indicated that: (1) the majority of participants had little or no opportunity to exercise self-determination over major life decisions (e.g., with whom and where to live, the recruitment and retention of care staff); (2) even in more mundane areas, such as where and when to eat, the majority of participants were not supported to exercise effective control; (3) variation in environmental opportunities to exercise self-determination was strongly related to a range of factors including participant ability, previous residential history, and structural and procedural aspects of the residential supports currently provided.

Staff stressors and staff outcomes in services for adults with intellectual disabilities: the Staff Stressor Questionnaire.

This paper reports on the development, psychometric properties, and validity of a self-report measure designed to assess potential stressors among staff in services for people with intellectual disabilities, the 33-item Staff Stressor Questionnaire (SSQ). A questionnaire including the SSQ and scales measuring staff outcomes was administered to 512 staff across seven services for people with intellectual disabilities. The SSQ was factor analyzed to produce seven subscales reflecting different potential stressors for staff: user challenging behavior; poor user skills; lack of staff support; lack of resources; low-status job; bureaucracy; and work-home conflict. The SSQ subscales showed adequate internal reliability in terms of Cronbach's alpha and mean inter-item correlations. Associations between SSQ subscale scores and different staff groups, and patterns of associations between SSQ subscales and a range of staff outcomes, provided evidence suggestive of the face-, construct-, and criterion-related validity of the questionnaire. The SSQ shows promise as a measure for assessing potential stressors for staff in services for people with intellectual disabilities. Further studies to examine the reliability, validity, and utility of the SSQ are recommended.

Mothers of children and adolescents with intellectual disability: social and economic situation, mental health status, and the self-assessed social and psychological impact of the child's difficulties.

BACKGROUND: Few large-scale studies with well-constructed samples have compared the socio-economic circumstances and social impact of raising a child with intellectual disability (ID). The aims of the present paper were to: (1) compare the socio-economic situation of mothers raising a child with ID to that of mothers of non-ID children; (2) assess the contribution of raising a child with ID to negative psychological outcomes for mothers; and (3) identify variables associated with negative psychological outcomes among mothers of children with ID. METHODS: The 1999 Office for National Statistics survey, Mental Health of Children and Adolescents in Great Britain, 1999, collected information on a multistage stratified random sample of 10 438 children between 5 and 15 years of age across 475 postal code sectors in England, Scotland and Wales. Secondary analysis was undertaken of the social and economic circumstances, and stress reported by 245 mothers of sampled children with ID and a comparison group of 9 481 mothers of sampled children who did not have ID. RESULTS: The results indicate that: (1) families supporting a child with ID were significantly economically disadvantaged when compared with families supporting a child who did not have ID; (2) when compared with mothers of sampled children who did not have ID, mothers of sampled children with ID reported that their child's difficulties resulted in greater social and psychological impact; (3) having a child with ID marginally reduced the odds of mothers screening positive for having mental health problems (once all other variables were taken into account); and (4) among mothers of children with ID, mental health problems were associated with the child's difficulties having a greater social impact, having a boy, the child experiencing more than one potentially stressful life event, poverty, receipt of means-tested welfare benefits and 'unhealthy' family functioning. CONCLUSIONS: These results highlight the importance of combating poverty among children with ID and their families, and the need to develop more complex models of understanding and intervention.

Toxic effects of capsaicin on keratinocytes and fibroblasts.

Pain management for partial-thickness burns and split-thickness skin graft donor sites remains a persistent problem. Topical capsaicin (trans-b-methyl-N-vanillyl-noneamide) has been successful for pain relief in postherpetic neuralgia, arthritis, and diabetic neuropathy. It is thought to work by inhibiting type C cutaneous factors and by releasing substance P, which is essential for wound healing. To evaluate the effects of topical capsaicin treatment on burn wounds and donor sites, an in vitro study was designed to consider cytotoxic effects of commercial concentrations of capsaicin on keratinocytes and fibroblasts. Human keratinocytes and human fibroblasts were grown in tissue culture and exposed to varying concentrations of capsaicin (0.025% weight/volume to 0.2% weight/volume). In addition, fibroblast-seeded collagen matrixes were exposed to capsaicin to evaluate the compound's ability to cause cytotoxic effects beneath the surface. Keratinocyte growth was reduced 21% to 31% in commercial concentrations of capsaicin 0.025% to 0.20% weight/volume. Fibroblasts were reduced 5% to 10% during the first 6 hours of exposure to capsaicin and 30% after 24 hours across the full range of concentrations tested. At concentrations of at least 0.1% weight/volume, capsaicin penetrated the collagen matrixes, resulting in fibroblast degeneration not only on the surface but also in the inner layers. On the basis of the fact that capsaicin was demonstrated to be cytotoxic to keratinocytes and fibroblasts and on the basis of its known detrimental effect on wound healing, it does not appear that topical capsaicin is indicated for the treatment of burns.
