Toward Actionable Practice Parameters for "Dual Diagnosis": Principles of Assessment and Management for Co-Occurring Psychiatric and Intellectual/Developmental Disability

Anticipating the outcomes: how young adults with developmental disabilities and co-occurring mental health conditions make decisions about disclosure of their mental health conditions at work

PURPOSE

Little is known about how young adults (YA) with developmental disabilities (DD) and co-occurring mental health conditions navigate workplace disclosure of their mental health condition(s). We sought to understand the guidance professionals provide regarding disclosure and the decisions YA makes about disclosure of mental health conditions.

METHODS

We conducted focus groups with professionals who support YA with DD to attain and maintain employment (n = 17) and individual interviews with YA with DD and co-occurring mental health conditions (n = 12; DD diagnoses: autism, n = 9, other DD, n = 3). We conducted content analysis to identify why, when, what, and to whom YA disclose their mental health condition and guidance provided regarding disclosure.

RESULTS

YA and professionals described disclosure decisions as largely influenced by perceived needs (i.e., need for accommodations) and anticipated positive (e.g., support) and negative (e.g., stigma, not being hired) outcomes. They largely constrained disclosure to work-relevant content. Many YA disclosed to coworkers with whom they were comfortable, though both YA and professionals agreed that initial disclosure should be limited to supervisors and/or human resources.

CONCLUSIONS

Workplaces may support disclosure-a necessity for the provision of accommodations-by cultivating an inclusive environment and openly demonstrating familiarity and comfort with employees with disabilities.IMPLICATIONS FOR REHABILITATIONProfessionals who support young adults with developmental disabilities and co-occurring mental health conditions should be well-versed in current laws and regulations on disclosure and reasonable workplace accommodations.Workplace culture is one major factor impacting how disclosure is handled, including whether the disclosure is required at all.Individuals with disabilities and professionals should recognize that timing, content, and decisions to disclose may vary by individuals' needs and workplace supports, and that change may occur over time.

The transition from child to adult health services for young adults with intellectual disabilities: An evaluation of a pilot of an online learning resource for Registered Nurses

AIM

This study formed the third phase of a national study on the experience of transition from child to adult health services for young adults with intellectual disabilities. The aim of this phase was to evaluate the accessibility and acceptability of an on-line learning resource for Registered Nurses.

BACKGROUND

The population of young adults with intellectual disabilities and complex needs is increasing. Consequently, more will move from child to adult healthcare, with evidence highlighting that for some their experiences of the transition process is poor. The main study provided contemporary evidence to raise the awareness of Registered Nurses of the needs of young adults with intellectual disabilities and their role in enabling an effective transition from child to adult services.

METHODS

The online learning resource was developed and piloted with Registered Nurses involved in the transition from child to adult health services for young adults with intellectual disabilities and complex needs. Data collection involved an online survey and semi-structured interviews.

RESULTS

Twelve Registered Nurses from 2 Scottish NHS Boards completed the questionnaire and 3 participated in a follow-up interview. The findings suggest that the mode of on-line delivery and most of the content of the learning resource were both acceptable and accessible to Registered Nurses across a range of areas of nursing practice. The learning resource was further adapted in response to the participant data.

CONCLUSION

This on-line learning resources offers the potential for Registered Nurses, and potentially other healthcare professionals to undertake evidence-based, structured further education regarding the effective transitions for young adults with intellectual disabilities and their families.

TWEETABLE ABSTRACT

Registered Nurses have key contributions to enable the transition from child to adult healthcare for young adults with intellectual disabilities.

Two Genetic Mechanisms in Two Siblings with Intellectual Disability, Autism Spectrum Disorder, and Psychosis

Intellectual disability (ID) and autism spectrum disorder (ASD) are complex neurodevelopmental disorders with high heritability. To search for the genetic deficits in two siblings affected with ID and ASD in a family, we first performed a genome-wide copy number variation (CNV) analysis using chromosomal microarray analysis (CMA). We found a 3.7 Mb microdeletion at 22q13.3 in the younger sister. This de novo microdeletion resulted in the haploinsufficiency of SHANK3 and several nearby genes involved in neurodevelopment disorders. Hence, she was diagnosed with Phelan–McDermid syndrome (PMS, OMIM#606232). We further performed whole-genome sequencing (WGS) analysis in this family. We did not detect pathogenic mutations with significant impacts on the phenotypes of the elder brother. Instead, we identified several rare, likely pathogenic variants in seven genes implicated in neurodevelopmental disorders: KLHL17, TDO2, TRRAP, EIF3F, ATP10A, DICER1, and CDH15. These variants were transmitted from his unaffected parents, indicating these variants have only moderate clinical effects. We propose that these variants worked together and led to the clinical phenotypes in the elder brother. We also suggest that the combination of multiple genes with moderate effects is part of the genetic mechanism of neurodevelopmental disorders.

Cognitive assessment using the Rapid Assessment for Developmental Disabilities, Second Edition (RADD-2)

BACKGROUND

Individuals with developmental disabilities (DD) often have severe impairments and maladaptive behaviours that make it difficult to reliably assess their cognitive abilities. Given these challenges, the Rapid Assessment of Developmental Disabilities, Second Edition (RADD-2), was designed to measure general cognitive ability in this population. The purpose of this study is to demonstrate the battery's psychometric properties when used with individuals with DD who have challenging behavioural and psychiatric conditions and for those who have limited verbal skills.

METHOD

The cognitive and adaptive behaviour skills of 193 children and adults with DD and considerable medical, behavioural and/or psychiatric problems were evaluated using the first and second editions of the RADD, Kaufmann Brief Intelligence Test - 2nd Edition, and Scales of Independent Behaviour - Revised Edition. Medication side effects and challenging behaviours were assessed using the Aberrant Behaviour Checklist.

RESULTS

There were no floor or ceiling effects on the RADD-2. Both the nonverbal index and total scores had strong concurrent validity with other abbreviated tests of intellectual ability and good discriminant validity from measures of adaptive behaviour and medication side effects. RADD-2 scores also had strong criterion validity as they successfully differentiated between all levels of intellectual functioning. Age and sex did not differentially affect RADD-2 performance, and the co-occurrence of psychiatric conditions did not negatively affect performance. The only medical condition associated with lower RADD-2 performance was epilepsy.

CONCLUSIONS

The RADD-2 can quantify the differential cognitive abilities of individuals with DD, even for those with minimal communication skills, challenging behaviours or severe medication side effects that can typically complicate assessment. This brief cognitive battery can be used to measure changes due to interventions, on the one hand, and progression of neurological disease, on the other.

Predictors of community-based employment for young adults with intellectual disability and co-occurring mental health conditions

PURPOSE

To identify predictors of community-based employment and employment quality for young adults ages 23-30 with intellectual disability and co-occurring mental health conditions (YA-ID-MH).

METHODS

We conducted secondary analysis of the 2017-2018 National Core Indicators^® (NCI^®) In-Person Survey. The NCI^® survey was conducted in 35 states and Washington DC. Participants: YA with ID, ages 23-30 who had complete data. We conducted multiple regression analyses to examine demographic and environmental predictors of community-based employment, in addition to employment quality indicators: hourly wages, hours worked, and job duration. We also descriptively examined job satisfaction.

RESULTS

YA-ID-MH were somewhat less likely to be employed per record review and self-report than YA with ID only, but these findings did not reach statistical significance. On average, YA with ID only had higher hourly wages and worked more hours than those with ID-MH, but there were no significant differences in job duration. For YA-ID-MH, predictors of employment included gender, race, level of ID, and residential setting. Multiple demographic and environmental factors predicted employment quality.

CONCLUSIONS

YA-ID-MH experience employment disparities compared to YA with ID only. Service providers should specifically attend to those at the highest risk of unemployment/low quality employment.IMPLICATIONS FOR REHABILITATIONYoung adults with intellectual/developmental disabilities and co-occurring mental health conditions (ID-MH) experience employment disparities.Young adults with ID-MH who are non-white and female may have particularly low employment rates and employment quality.Societal-level interventions to address racial and gender-based bias may support individuals with ID-MH to acquire and maintain jobs by addressing disparities in social networks/social capital and ensuring equitable service provision and supports for those at the highest risk for unemployment.Policy makers should consider additional funding for employment services for transition-age youth with ID-MH, particularly those from marginalized populations.
