Reliability and the measurement of activity limitations (ADLs) for children with special health care needs (CSHCN) living in the community

A psychometric evaluation of the interRAI Child and Youth Mental Health instruments (ChYMH) anxiety scale in children with and without developmental disabilities

BACKGROUND

With 10 to 20% of Canadian children suffering with mental illness, the importance of early identification and accurate assessment systems is clear. Unfortunately, many do not receive the mental health treatment necessary and wait-times for assessment can span up to a year. In response, the interRAI suite of assessments were designed to comprehensively assess early signs of mental health impairments in children from birth to 18 years.

METHODS

This study assesses the psychometric properties of the Anxiety Scale and addresses the identification of anxiety within children diagnosed with intellectual and developmental disabilities (IDD); a commonly underrepresented sample in mental health psychometric studies. Data was collected from children aged 4-18 years in three different samples.

RESULTS

Results indicated reliable internal consistency and factor structure, as well as moderate-to-strong convergent validity.

CONCLUSIONS

We conclude that the Anxiety Scale exhibits psychometric qualities which demonstrate its clinical utility for use within a child sample, as well as in children with IDD. The findings provide support to a larger body of research which show consistent psychometric rigour of the interRAI measures.

The Pediatric Personal Care Allocation Model for Home Care (PCAM): A Personal Care Case-Mix Model for Children Facing Special Health Care Challenges

Background:

State Medicaid programs in the United States provide services to children with special health care challenges through the Early Prevention, Screening, Diagnostic, and Treatment program. One element of the services provided is Medicaid Personal Care Services (PCS), which are intended to correct or ameliorate any functional impairments faced by a child or youth (C/Y) in the community. Previous research indicates that considerable variation in the allocation of PCS depends on the assessor. A case-mix model is developed that might make the distribution of such services more uniform and equitable.

Data:

The sample in this research includes 2708 C/Y aged 4 to 20 who were receiving PCS in Texas in 2008.

Results:

A case-mix model was developed that groups sample members into 33 categories based on the number of hours of PCS authorized by an assessor. The Pediatric Personal Care Allocation Model (PCAM) explains 27% of the variance in the allocation of PCS hours.

Discussion:

The implementation of the PCAM should provide guidance to assist in ensuring that C/Y facing similar functional challenges receive similar levels of PCS. However, implementation of any case-mix model is only a first step in moving to a prospective payment system for PCS.

The Pediatric Home Care/Expenditure Classification Model (P/ECM): A Home Care Case-Mix Model for Children Facing Special Health Care Challenges

Case-mix classification and payment systems help assure that persons with similar needs receive similar amounts of care resources, which is a major equity concern for consumers, providers, and programs. Although health service programs for adults regularly use case-mix payment systems, programs providing health services to children and youth rarely use such models. This research utilized Medicaid home care expenditures and assessment data on 2,578 children receiving home care in one large state in the USA. Using classification and regression tree analyses, a case-mix model for long-term pediatric home care was developed. The Pediatric Home Care/Expenditure Classification Model (P/ECM) grouped children and youth in the study sample into 24 groups, explaining 41% of the variance in annual home care expenditures. The P/ECM creates the possibility of a more equitable, and potentially more effective, allocation of home care resources among children and youth facing serious health care challenges.

Medicaid personal care services for children with intellectual disabilities: what assistance is provided? When is assistance provided?

We report on the nature and timing of services provided to children with an intellectual disability (ID) identified by a new comprehensive assessment and care planning tool used to evaluate children's needs for Medicaid Personal Care Services (PCS) in Texas. The new assessment procedure resulted from a legal settlement with the advocacy community. Participants in the study were 1,109 children ages 4-20 with an intellectual disability diagnosis who were assessed between January and April of 2010. The need for assistance is higher on Saturday and Sunday, when school services are not available. We report differences in service patterns for children who vary in ID severity. Finally, we consider the implications of our results for policies and programs that serve families with children with an ID.

Summarizing activity limitations in children with chronic illnesses living in the community: a measurement study of scales using supplemented interRAI items

Background

To test the validity and reliability of scales intended to measure activity limitations faced by children with chronic illnesses living in the community. The scales were based on information provided by caregivers to service program personnel almost exclusively trained as social workers. The items used to measure activity limitations were interRAI items supplemented so that they were more applicable to activity limitations in children with chronic illnesses. In addition, these analyses may shed light on the possibility of gathering functional information that can span the life course as well as spanning different care settings.

Methods

Analyses included testing the internal consistency, predictive, concurrent, discriminant and construct validity of two activity limitation scales. The scales were developed using assessment data gathered in the United States of America (USA) from over 2,700 assessments of children aged 4 to 20 receiving Medicaid Early and Periodic Screening, Diagnostic and Treatment (EPSDT) services, specifically Personal Care Services to assist children in overcoming activity limitations. The Medicaid program in the USA pays for health care services provided to children in low-income households. Data were collected in a single, large state in the southwestern USA in late 2008 and early 2009. A similar sample of children was assessed in 2010, and the analyses were replicated using this sample.

Results

The two scales exhibited excellent internal consistency. Evidence on the concurrent, predictive, discriminant, and construct validity of the proposed scales was strong. Quite importantly, scale scores were not correlated with (confounded with) a child's developmental stage or age. The results for these scales and items were consistent across the two independent samples.

Conclusions

Unpaid caregivers, usually parents, can provide assessors lacking either medical or nursing training with reliable and valid information on the activity limitations of children. One can summarize these data in scales that are both internally consistent and valid. Researchers and clinicians can use supplemented interRAI items to provide guidance for professionals and programs serving children, as well as older persons. This research emphasizes the importance of developing medical information systems that allow one to integrate information not only across care settings but also across an individual's life course.

Medicaid Personal Care Services and caregivers' reports of children's health: the dynamics of a relationship

OBJECTIVE

To investigate the relationship between Medicaid Personal Care Services (PCS) and caregivers' reports of activity (activities of daily living [ADL]) limitations for children with chronic health problems.

DATA SOURCES/STUDY SETTING

Primary data collected in 2008 and 2009. A state Medicaid program was the setting. The focus was children receiving Medicaid PCS.

DATA COLLECTION

Medicaid case managers assessed children to determine their need for PCS, using information provided by the child or informal caregivers. Two thousand seven hundred assessments were provided to researchers directly from case managers.

PRINCIPAL FINDINGS

Medical conditions and impairments explained 58 percent of the variance in the child's activity limitations. Activity limitations and problem behaviors explained 28 percent of the variance in PCS hours authorized. Which case manager completed the assessment also played a substantial role in determining hours of care.

CONCLUSIONS

Caregivers' reports of the severity of a child's activity limitations effectively summarize the effects of conditions and impairments on the child's ADL performance and have a significant impact on the level of services provided. Assessors often respond differently to children's characteristics and circumstances as they move from assessment to decisions concerning care provision. Our results imply that the provision of appropriate services may be enhanced when both case managers and caregivers play an active role in decisions concerning care provision.
