A feasibility study of behavioural activation for depressive symptoms in adults with intellectual disabilities

Adapting psychological interventions for people with severe and profound intellectual disabilities: A behavioural activation exemplar

BACKGROUND

People with severe to profound intellectual disabilities experience similar or higher levels of depression than those with more mild intellectual disabilities. Yet, there is an absence of evidence about how to adapt existing psychological therapies for this population.

METHOD

A behavioural activation intervention (BeatIt) for people with mild to moderate intellectual disabilities was adapted for people with severe to profound intellectual disabilities and depression. Key considerations include: (i) beginning with a more in-depth assessment process; (ii) including the person in session activities and developing a relationship with them; (iii) formulation and the use of film to document the link between activity and mood; and (iv) addressing barriers to change at an individual and inter-personal level and considering how the carer could support the person's engagement in activity.

RESULTS

Successfully adapting BeatIt represents a first step towards gathering evidence about the effectiveness of behavioural activation for people with severe to profound intellectual disabilities.

Mechanisms of change in Behavioral Activation: Adapting depression treatment for autistic people

Despite high rates of co-occurring depression, few studies have developed or adapted treatments targeting depressive symptoms for autistic adults. Behavioral activation is widely accepted as an empirically-supported approach for treating depression in other populations. Careful attention to the mechanisms targeted by behavioral activation is an essential step toward adapting behavioral activation protocols for use with autistic adults. We consider the mechanisms targeted by behavioral activation and provide a framework for research to explore the facilitators and barriers to the use of behavioral activation to treat depression in autistic adults. Drawing upon clinical experience and extant literature, the suggestions presented are aimed at highlighting considerations for clinicians wanting to use behavioral activation programs in their clinical practices with autistic adults and to promote the research needed to establish behavioral activation as an evidence-based practice for treating depression in adults on the autism spectrum.

Stakeholder perspectives on intensive support teams for adults with intellectual disabilities who display behaviour that challenges in England

BACKGROUND

Adults with intellectual disabilities often display behaviour that challenges that is a result of biological differences, psychological challenges, and lack of appropriate social support. Intensive Support Teams (IST) are recommended to support the care needs of this group and avoid hospitalisation. However, little attention has been paid to the perspectives of stakeholders who manage, work in, or use ISTs.

METHOD

Interviews and focus groups were conducted with 50 stakeholders (IST service managers and professionals, adults with intellectual disabilities, and family and paid carers) of ISTs. Services operated according to one of two service models previously identified in ISTs in England (enhanced or independent).

RESULTS

Thematic analysis identified accessible and flexible support, individualised care, and the involvement of carers and other relevant agencies in management plans and reviews as features of good IST care highlighted by all stakeholder groups. IST managers and professionals described the key challenges of current IST provision as unclear referral criteria, limited interfaces with other local services, and perceived threats associated with funding and staff retention. Findings were similar between the two IST models.

CONCLUSIONS

ISTs are able to offer care and specialist support that is valued by families, service users and other care providers. However, they face several operational challenges that should be addressed if ISTs are to reach their potential along with community intellectual disability services in supporting adults with intellectual disabilities who display behaviour that challenges in the community.

Behavioral Activation (BA) in the Management of Depression in an Adolescent with Down Syndrome in Dubai

Depression has been commonly treated with psychotherapy and/or pharmacotherapy for several decades. Ongoing research in the field has suggested promise for behavioral activation (BA), a form of psychotherapeutic intervention, as a means of increasing engagement in adaptive activities and developing skills to counter avoidance in individuals suffering from depression. In this case report, we present the treatment course of BA for an adolescent with Down syndrome (DS), presenting with depression. A multidisciplinary approach was utilized in developing a personalized management plan for the patient since the initial presentation. Sessions at the outpatient psychiatry clinic alternated between in-person visits and virtual ones, due to circumstances associated with physical distancing with the COVID-19 pandemic. Parents were included as integral parts of the management plan, and education, strategic implementation of BA, and barriers to care were discussed extensively to support the adolescent through the course of her treatment. Within 6 weeks of introducing BA, positive outcomes were noted in the patient, with the resolution of her clinical depression. In this report, we discuss BA further as a potentially effective therapeutic approach to the treatment of depressive symptoms in children and adolescents with DS and intellectual disabilities.

Is behavioral activation an effective and acceptable treatment for co-occurring depression and substance use disorders? A meta-analysis of randomized controlled trials

BACKGROUND

Depression often co-occurs with substance use problems and is associated with poor treatment outcomes. While the efficacy of behavioral activation (BA) has been tested in clinical trials with substance users, outcomes have not yet been quantitatively synthesized.

METHODS

The study team performed a random effects meta-analysis of the randomized clinical trial evidence base. We compared outcomes for individual or group BA against passive or active controls. We also compared attendance and dropout rates. The meta-analysis used a grading of recommendations assessment, development, and evaluation (GRADE) approach to assess the quality of each meta-analytic comparison.

RESULTS

We included five trials in the meta-analysis (N = 195). The analysis found no significant differences between BA and controls with regard to depression (Post-treatment: k = 5; N = 195; SMD: 0.19, CI -0.10 to 0.49; p = 0.20; GRADE = Low; Follow-up: k = 5; N = 195; SMD: -0.10, CI -0.51 to -0.30; p = 0.62; GRADE = Low) or substance use (post-treatment: k = 4; N = 151; SMD: 0.14, CI -0.33 to -0.6; p = 0.57, GRADE = Low; Follow-up: k = 4; N = 151; SMD: 0.17, CI -0.34 to 0.69; p = 0.51, GRADE = Low) and there was little evidence of publication bias. The average session attendance rate for BA was 72%. An average dropout rate of 35% was reported for both BA and comparator conditions.

CONCLUSION

BA does not emerge as a differentially efficacious treatment for comorbid depression and substance use disorders, although it does appear to be an acceptable treatment option. Our confidence in the results are limited by the number and quality of the original studies and the possibility of the effect of small study bias. We make suggestions for improving the methodological quality and direction of future BA trials.

The experiences of therapists providing psychological treatment for adults with depression and intellectual disabilities as part of a randomised controlled trial

BACKGROUND

Health professionals were trained to deliver adapted psychological interventions for depression to people with learning disabilities and depression alongside a supporter. Exploring the delivery of psychological interventions can help increase access to therapy.

METHOD

Twenty-seven participants took part in six focus groups, and the data were subject to a Framework Analysis.

RESULTS

The structure and focus of the manualised therapies, and the use of specific techniques were perceived as key to service-user engagement. Supporters' involvement was valued by therapists if they had a good relationship and regular contact with the individual they supported. Regular clinical supervision was regarded as vital in understanding their role, assessing progress and delivering the interventions.

CONCLUSIONS

The findings highlight that health professionals can embrace a focussed therapeutic role and increase access to psychological therapies for people with intellectual disabilities.

Intelligence trajectories in adolescents and adults with down syndrome: Cognitively stimulating leisure activities mitigate health and ADL problems

GOALS

This study examined: (a) crystallized/fluid intelligence trajectories of adolescents and adults with Down syndrome; and (b) the contribution of endogenous (health, activities of daily living-ADL) and exogenous (cognitively stimulating leisure activities) factors on adults' intelligence with age.

METHOD

Four cohorts (N = 80) with Down syndrome participated: adolescents (ages 16-21) and adults (ages 30-45, 46-60 and 61+). All completed Vocabulary and Similarities (crystallized) and Block Design and Raven (fluid) intelligence tests (WAIS-III^HEB , Wechsler, 2001).

RESULTS

The 30-45 cohort significantly outperformed the 16-21 cohort. Except for Vocabulary, which remained stable, onset of decline was at 40-50. Age-related declining health and ADL correlated with participants' lower fluid intelligence, but cognitive leisure activities mitigated this influence.

CONCLUSIONS

Intelligence development into adulthood supported the continuous trajectory and compensation age theory, rather than accelerated or stable trajectories. Not only endogenous factors but also exogenous factors determined intelligence levels in adults with Down syndrome, supporting cognitive activity theory.

Investigating the potential clinical utility of therapeutic techniques based on eidetic imagery as adapted by the Eidetic Model of Growth (EMG) for people with intellectual disability (ID)

Eidetic model of growth (EMG) is a form of psychotherapy developed for people with intellectual disabilities (ID). EMG is based on the theoretical tenets of eidetic psychotherapy of Akhter Ahsen, which uses eidetic imagery as its major therapeutic tool. The literature review did not find any empirical study on eidetic imagery-based psychotherapy for people with ID except reviews and case histories. This study investigates the clinical utility of therapeutic techniques based on eidetic imagery as developed by Ahsen and Syed.

In this study thirty participants with mild and moderate ID were recruited. Participants were recruited from the services for people with ID. These services were contacted to recruit participants who had experiential (i.e., abuse, trauma etc.), emotional (i.e., bereavement, attachment problems), psychiatric (i.e., anxiety, depression) and behavioural (i.e., anger, aggression) problems and to seek consent from the potential participants. The Anxiety Depression and Mood Scale (ADAMS) was administered to the participants before the therapy started, after every 5^th session and once the therapy was terminated. The statistical analysis of the pre-therapy and post-therapy scores of participants on the ADAMS was carried out to measure the therapeutic outcome.

Paired-sample t-test revealed a significant difference between the pre-therapy and post-therapy scores of participants on ADAMS, with a large effect size (d = 1.54). The result indicates existence of eidetic imagery in people with ID and its promising therapeutic utility.

Verhaltenstherapie bei Erwachsenen mit intellektueller Beeinträchtigung: Eine systematische Review

<b><i>Hintergrund:</i></b> Menschen mit intellektueller Beeinträchtigung (IB) sind häufig von psychischen Störungen betroffen. Gleichzeitig ist die psychotherapeutische Versorgung in diesem Bereich bisher unzureichend, und die Evidenz bezüglich der Wirksamkeit verhaltenstherapeutischer Interventionen bei Erwachsenen mit IB ist unklar. <b><i>Ziele:</i></b> Eine systematische Literaturrecherche in den Datenbanken PubMed, PsycINFO und Google Scholar wurde durchgeführt, um die aktuelle Studienlage zu verhaltenstherapeutischen Interventionen bei Menschen mit IB zu evaluieren. Ausgewählt wurden Studien zu verhaltenstherapeutischen Verfahren bei psychischen Störungen und Problemverhalten im Erwachsenenalter. <b><i>Ergebnisse:</i></b> Zweiunddreißig Studien entsprachen den Einschlusskriterien; es wurden sowohl einzeltherapeutische als auch gruppentherapeutische Interventionen eingeschlossen. Für Menschen mit leichter IB (IQ 50–69) und teilweise auch bei mittlerer IB (IQ 35–49) konnten in einigen Studien Hinweise auf effektive und gut umsetzbare Verfahren gefunden werden. Deutliche positive Effekte aus verschiedenen Studien zeigten sich bei depressiven Symptomen und bei aggressivem Verhalten sowohl im ambulanten wie auch im forensischen Setting. Für Angstsymptome und bei Raucherentwöhnung liegen ebenfalls positive Befunde vor. Bei psychotischen Störungen und bei pathologischem Horten muss die Wirksamkeit von verhaltenstherapeutischen Interventionen noch als unklar eingeschätzt werden. <b><i>Schlussfolgerungen:</i></b> Es bedarf weiterer Forschung (insbesondere randomisierter kontrollierter Studien mit aktiven Kontrollbedingungen), in der differenzierter überprüft wird, welche Aspekte der Therapien/welche Settingbedingungen die Effektivität bei den verschiedenen Graden der IB beeinflussen.

How service-users with intellectual disabilities understand challenging behaviour and approaches to managing it

BACKGROUND

This study explored understandings that service-users with intellectual disabilities and challenging behaviour held around their behaviour, what shaped these understandings, and the relationship between how behaviours are managed and well-being.

METHODS

Eight participants (three female, five male) partook in individual semi-structured qualitative interviews. Interviews were transcribed and analysed using interpretative phenomenological analysis.

RESULTS

Three master themes emerged from this analysis: (a) challenging behaviour can be explained via an internal or external frame of reference, with each framework having different implications for how participants attempted to manage behaviour. (b) Positive relationships provide a long-term buffer to challenging behaviour, with positive relationships with family, staff and peers operating through different mechanisms to achieve this. (c) A greater ability to exert power and control in day-to-day life was perceived to reduce challenging behaviour in the long term.

CONCLUSIONS

Implications for practice are discussed.

Behavioural activation versus guided self-help for depression in adults with learning disabilities: the BeatIt RCT

BACKGROUND

Depression is the most prevalent mental health problem among people with learning disabilities.

OBJECTIVE

The trial investigated the clinical effectiveness and cost-effectiveness of behavioural activation for depression experienced by people with mild to moderate learning disabilities. The intervention was compared with a guided self-help intervention.

DESIGN

A multicentre, single-blind, randomised controlled trial, with follow-up at 4, 8 and 12 months post randomisation. There was a nested qualitative study.

SETTING

Participants were recruited from community learning disability teams and services and from Improving Access to Psychological Therapies services in Scotland, England and Wales.

PARTICIPANTS

Participants were aged ≥ 18 years, with clinically significant depression, assessed using the Diagnostic Criteria for Psychiatric Disorders for use with Adults with Learning Disabilities. Participants had to be able to give informed consent and a supporter could accompany them to therapy.

INTERVENTIONS

BeatIt was a manualised behavioural activation intervention, adapted for people with learning disabilities and depression. StepUp was an adapted guided self-help intervention.

MAIN OUTCOME MEASURES

The primary outcome measure was the Glasgow Depression Scale for people with a Learning Disability (GDS-LD). Secondary outcomes included carer ratings of depressive symptoms and aggressiveness, self-reporting of anxiety symptoms, social support, activity and adaptive behaviour, relationships, quality of life (QoL) and life events, and resource and medication use.

RESULTS

There were 161 participants randomised (BeatIt, n = 84; StepUp, n = 77). Participant retention was strong, with 141 completing the trial. Most completed therapy (BeatIt: 86%; StepUp: 82%). At baseline, 63% of BeatIt participants and 66% of StepUp participants were prescribed antidepressants. There was no statistically significant difference in GDS-LD scores between the StepUp (12.94 points) and BeatIt (11.91 points) groups at the 12-month primary outcome point. However, both groups improved during the trial. Other psychological and QoL outcomes followed a similar pattern. There were no treatment group differences, but there was improvement in both groups. There was no economic evidence suggesting that BeatIt may be more cost-effective than StepUp. However, treatment costs for both groups were approximately only 4-6.5% of the total support costs. Results of the qualitative research with participants, supporters and therapists were in concert with the quantitative findings. Both treatments were perceived as active interventions and were valued in terms of their structure, content and perceived impact.

LIMITATIONS

A significant limitation was the absence of a treatment-as-usual (TAU) comparison.

CONCLUSIONS

Primary and secondary outcomes, economic data and qualitative results all clearly demonstrate that there was no evidence for BeatIt being more effective than StepUp.

FUTURE WORK

Comparisons against TAU are required to determine whether or not these interventions had any effect.

Supporting people with intellectual disabilities in psychological therapies for depression: A qualitative analysis of supporters' experiences

BACKGROUND

Clinicians recommend including carers or others in a supporting role in the therapy as an important adaptation of psychological therapies for people with intellectual disabilities. This nested qualitative study from a larger trial explored supporters' experiences of supporting people with intellectual disabilities receiving behavioural activation or guided self-help therapies for depression.

METHOD

Twenty-one purposively sampled supporters were interviewed. The semi-structured interviews were subject to framework analysis, covering expectations of therapy, views of therapy sessions, relationships with therapist and participant, and perceived changes.

RESULTS

Supporters were positive about both therapies and reported both therapy-specific and nonspecific therapeutic factors that had significant positive impacts on people's lives. Most supporters reported their involvement contributed to the interventions' effectiveness, and helped establish closer relationships to the people they were supporting.

CONCLUSIONS

The presence of supporters within psychological therapies for people with intellectual disabilities can be an effective adaptation to therapies for this population.

Non-pharmacological interventions for adults with intellectual disabilities and depression: a systematic review

BACKGROUND

Although high rates of depression symptoms are reported in adults with intellectual disabilities (IDs), there is a lack of knowledge about non-pharmacological treatment options for depression in this population. The first research question of this paper is: Which non-pharmacological interventions have been studied in adults with ID and depression? The second research question is: What were the results of these non-pharmacological interventions?

METHOD

Systematic review of the literature with an electronic search in six databases has been completed with hand searches. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines have been followed. Selected studies met predefined inclusion criteria.

RESULTS

Literature search resulted in 4267 papers of which 15 met the inclusion criteria. Five different types of non-pharmacological interventions have been studied: cognitive behavioural therapy, behavioural therapy, exercise intervention, social problem-solving skills programme and bright light therapy.

CONCLUSION

There are only a few studies of good quality evaluating non-pharmacological interventions for adults with ID and depression. Some of these studies, especially studies on cognitive behavioural therapy, show good results in decreasing depressive symptoms. High-quality randomised controlled trials evaluating non-pharmacological interventions with follow-up are needed.

Development of a supported self-management intervention for adults with type 2 diabetes and a learning disability

BACKGROUND

Although supported self-management is a well-recognised part of chronic disease management, it has not been routinely used as part of healthcare for adults with a learning disability. We developed an intervention for adults with a mild or moderate learning disability and type 2 diabetes, building on the principles of supported self-management with reasonable adjustments made for the target population.

METHODS

In five steps, we:Clarified the principles of supported self-management as reported in the published literatureIdentified the barriers to effective self-management of type 2 diabetes in adults with a learning disabilityReviewed existing materials that aim to support self-management of diabetes for people with a learning disabilitySynthesised the outputs from the first three phases and identified elements of supported self-management that were (a) most relevant to the needs of our target population and (b) most likely to be acceptable and useful to themImplemented and field tested the intervention.

RESULTS

The final intervention had four standardised components: (1) establishing the participant's daily routines and lifestyle, (2) identifying supporters and their roles, (3) using this information to inform setting realistic goals and providing materials to the patient and supporter to help them be achieved and (4) monitoring progress against goals.Of 41 people randomised in a feasibility RCT, thirty five (85%) completed the intervention sessions, with over three quarters of all participants (78%) attending at least three sessions.Twenty-three out of 40 (58%) participants were deemed to be very engaged with the sessions and 12/40 (30%) with the materials; 30 (73%) participants had another person present with them during at least one of their sessions; 15/41 (37%) were reported to have a very engaged main supporter, and 18/41 (44%) had a different person who was not their main supporter but who was engaged in the intervention implementation.

CONCLUSIONS

The intervention was feasible to deliver and, as judged by participation and engagement, acceptable to participants and those who supported them.

Comparison of behavioural activation with guided self-help for treatment of depression in adults with intellectual disabilities: a randomised controlled trial

BACKGROUND

Psychological therapies are first-line interventions for depression, but existing provision is not accessible for many adults with intellectual disabilities. We investigated the clinical and cost-effectiveness of a behavioural activation intervention (BeatIt) for people with intellectual disabilities and depression. BeatIt was compared with a guided self-help intervention (StepUp).

METHODS

We did a multicentre, single-blind, randomised, controlled trial with follow-up at 4 months and 12 months after randomisation. Participants aged 18 years or older, with mild to moderate intellectual disabilities and clinically significant depression were recruited from health and social care services in the UK. The primary outcome was the Glasgow Depression Scale for people with a Learning Disability (GDS-LD) score at 12 months. Analyses were done on an intention-to-treat basis. This trial is registered with ISCRTN, number ISRCTN09753005.

FINDINGS

Between Aug 8, 2013, and Sept 1, 2015, 161 participants were randomly assigned (84 to BeatIt; 77 to StepUp); 141 (88%) participants completed the trial. No group differences were found in the effects of BeatIt and StepUp based on GDS-LD scores at 12 months (12·03 [SD 7·99] GDS-LD points for BeatIt vs 12·43 [SD 7·64] GDS-LD points for StepUp; mean difference 0·26 GDS-LD points [95% CI -2·18 to 2·70]; p=0·833). Within-group improvements in GDS-LD scores occurred in both groups at 12 months (BeatIt, mean change -4·2 GDS-LD points [95% CI -6·0 to -2·4], p<0·0001; StepUp, mean change -4·5 GDS-LD points [-6·2 to -2·7], p<0·0001), with large effect sizes (BeatIt, 0·590 [95% CI 0·337-0·844]; StepUp, 0·627 [0·380-0·873]). BeatIt was not cost-effective when compared with StepUp, although the economic analyses indicated substantial uncertainty. Treatment costs were only approximately 3·6-6·8% of participants' total support costs. No treatment-related or trial-related adverse events were reported.

INTERPRETATION

This study is, to our knowledge, the first large randomised controlled trial assessing individual psychological interventions for people with intellectual disabilities and mental health problems. These findings show that there is no evidence that BeatIt is more effective than StepUp; both are active and potentially effective interventions.

Vision assessment in persons with intellectual disabilities

PURPOSE

To investigate the degree of visual acuity in workers with intellectual disabilities and the impact of vision on their working conditions.

METHODS

We recruited 224 workers (mean age 43.77 years, SD ± 12.96; range, 19-72 years) from a workshop for those with intellectual disabilities, to participate in a vision examination program. The assessment consisted of objective refraction, visual acuity, ocular motility, near-point of convergence, cover/uncover test, stereo acuity and colour perception. Individuals with vision deficits were fitted with spectacles following the screening program.

RESULTS

Within the past three years, 38.9 per cent of the participants received eye care, 14.3 per cent of participants had not received eye care in more than three years, and 6.7 per cent had not received any eye care. As many as 39.7 per cent of participants did not know whether they had ever received eye care. Entering visual acuity for far vision was 0.52 dec (-0.29 logMAR) and 0.42 dec (-0.38 logMAR) for near vision. Only 14.9 per cent, 11 of all participants aged ≥50 years, owned spectacles for near vision before the examination. After subjective determination of refraction, best corrected visual acuity for far vision was 0.61 dec (-0.22 logMAR) and 0.56 dec (-0.25 logMAR) for near vision (in both cases with p < 0.001). After the examination, 44.6 per cent (33) of all workers aged ≥50 years received a recommendation for reading or bifocal spectacles. In 46 per cent of workers, the threshold of stereopsis was higher than 63 arc seconds, and some form of colour vision deficiency was measured in 12.5 per cent of participants.

CONCLUSIONS

Workers with intellectual disabilities are often unaware of their visual deficits. We found that some of their abnormalities can be solved by appropriate optical means and that they could benefit from regular eye care. These workers should be encouraged to be tested and to improve their vision with appropriate lenses.

People with intellectual disability who are ageing: Perceived needs assessment

Background/Objective: Ageing and progressive increase in life expectancy in people with intellectual disability present significant challenges. The present study is to examine the needs that arise in the aging process of this population. To detect these needs is fundamental to ensure personal wellbeing; almost no psychometrically sound instruments have been developed. Method: A structured interview was developed and evaluated by a panel of 20 experts to obtain evidence of content validity. The interview was then applied to 1,173 people with intellectual disability. The ages ranged from 35 to 80 (M = 52.27; SD = 7.5). Results: The interview consisted of 93 items evaluating four areas: perceived needs, personal problems, future perspectives, and solutions required. The results demonstrated the proximity and relationship of the various needs evaluated. In addition it was observed that those with intellectual disability who were older, male and users of residential services tended to indicate more needs, problems, and required more solutions. Conclusions: The instrument has adequate evidence of validity, allowing the evaluation of specific needs of people with intellectual disability. The results advocate the design of transversal intervention policies in order to effectively meet the needs and requirements of this population.

Translation and validation of the Spanish version of the Health of the Nation Outcome Scales for People with Learning Disabilities (HoNOS-LD)

INTRODUCTION

The Health of the Nation Outcome Scales for People with Learning Disabilities (HoNOS-LD) is a brief instrument that assesses functioning in people with intellectual development disorder and mental health problems/behaviour disorders. The aim of the present study was to examine the evidence on the validity of the scores based on the Spanish version of the HoNOS-LD.

MATERIAL AND METHODS

The study included 111 participants that were assessed by the Spanish version of the HoNOS-LD and other questionnaires that measured different variables related to the scale. Thirty-three participants were assessed by 2 examiners, and retested 7 days later, in order to study inter-examiner reliability and test-retest reliabilities.

RESULTS

Based on clinical and conceptual criteria, and on the results of the parallel analysis, a factorial solution with one factor was selected. Internal consistency was good (Omega coefficient of 0.87). Inter-examiner and test-retest reliabilities were excellent (intraclass correlation coefficients of 0.95 and 0.98, respectively). Correlations between sections of the HoNOS-LD and the related instruments showed the expected direction, and were highly significant (P<.001), and the HoNOS-LD score increased with the intensity of the support required by the participants. These results showed evidence of the validity of association with other external variables.

CONCLUSIONS

The Spanish version of the HoNOS-LD is a brief, valid and reliable instrument, which will enable a routine assessment of functioning for different uses, including diagnosis and intervention.

Using 'candidacy' as a framework for understanding access to mainstream psychological treatment for people with intellectual disabilities and common mental health problems within the English Improving Access to Psychological Therapies service

BACKGROUND

The Improving Access to Psychological Therapies (IAPT) service was established to address common mental health problems among the English population in a timely manner in order to counter the social and economic disadvantage accompanying such difficulties. Using the concept of candidacy, we examined how the legitimacy of claims by people with intellectual disabilities to use this service is facilitated or impeded.

METHOD

We used a sequential mixed methods design. We completed 21 interviews with a range of stakeholders, including people with intellectual disabilities and their carers. Themes from the interviews were used to design an online survey questionnaire that was returned by 452 staff from IAPT and specialist intellectual disability services.

RESULTS

Using the candidacy framework, we noted that eligibility and access to IAPT were achieved through dynamic and iterative processes of negotiation involving people with intellectual disabilities and their supporters on one side and IAPT staff and service structures on the other. Barriers and facilitators were apparent throughout the seven dimensions of candidacy (identification, navigation, permeability of services, appearances, adjudications, offers and resistance and operating conditions) and were linked to discourses relating to the character and purpose of IAPT and specialist intellectual disability services.

CONCLUSIONS

Opportunities exist for some people with intellectual disabilities to assert their candidacy for IAPT input, although there are barriers at individual, professional, organisational and structural levels. More attention needs to be paid to how principles of inclusiveness are operationalised within IAPT teams and to the mental health facilitation role of specialist intellectual disability staff.

Interventions for adults with mild intellectual disabilities and mental ill-health: a systematic review

BACKGROUND

People with intellectual disabilities have very high rates of mental ill health. Standard psychosocial interventions designed for the general population may not be accessible for people with mild intellectual disabilities, and drug usage tends to be modified - 'start low and go slow'. This systematic review aims to synthesise the evidence on psychological, pharmacological and electroconvulsive therapy (ECT) interventions for adults with mild intellectual disabilities and mental ill health.

METHOD

PRISMA guidelines were followed. Medline, Embase, PsycINFO and CINAHL were searched, as was grey literature and reference lists of selected papers. Papers were selected based on pre-defined inclusion and exclusion criteria. A proportion of papers were double reviewed. Data was extracted using a structured table.

STUDY REGISTRATION

PROSPERO 2015:CRD42015015218.

RESULTS

Initially, 18 949 records were identified. Sixteen studies were finally selected for inclusion; seven on psychological therapies, two on group exercise, five on antipsychotics and two on antidepressants. They do not provide definitive evidence for effectiveness of psychosocial interventions, nor address whether starting low and going slow is wise, or causes sub-optimum therapy.

CONCLUSIONS

There are few evidence-based interventions for people with mild intellectual disabilities and mental ill-health; existing literature is limited in quantity and quality. Group cognitive-behavioural therapies have some supporting evidence - however, further randomised control trials are required, with longer-term follow-up, and larger sample sizes.

BEAT-IT: Comparing a behavioural activation treatment for depression in adults with intellectual disabilities with an attention control: study protocol for a randomised controlled trial

BACKGROUND

Depression appears to be more enduring amongst people with intellectual disabilities, suggesting that it is a more chronic problem or more poorly managed in this population. This is not helped by a lack of evidence about the effectiveness of psychological therapies for people who have intellectual disabilities and depression. Behavioural activation, which aims to counteract depression by increasing individuals' level of meaningful activity and their exposure to positive reinforcers, has proven to be as effective as cognitive behavioural therapy in the general population. Given that this therapy makes fewer communicative demands and focuses on activity, it was thought that behavioural activation would be both accessible and apt for people with intellectual disabilities, who are often socially marginalised.

METHODS/DESIGN

This study is a multi-centre single-blind randomised controlled trial of behavioural activation versus a self-help attention control intervention for depression in adults with mild/moderate intellectual disabilities. The study has an internal pilot in one centre, to establish that recruitment can be built up and sustained at the required level, before being rolled out across the other sites. One hundred sixty-six participants will be randomly assigned to the behavioural activation or self-help interventions, which will be delivered to individuals with mild to moderate intellectual disabilities, accompanied by someone who provides them with regular support. Both interventions are manualised and will be delivered over a period of approximately 4 months. The primary outcome measure will be the Glasgow Depression Scale, a self-report measure which is completed at baseline and 4 and 12 months post-randomisation. Secondary outcomes include measures of participants' activity levels, proxy reports of depressive symptoms, and cost-effectiveness.

DISCUSSION

The study will provide evidence about the effectiveness of behavioural activation for depression, adapted for people who have mild/moderate intellectual disabilities, and will inform the delivery of psychological therapies to people with intellectual disabilities in practice.
