About the PSC
The Pediatric Symptom Checklist is a one-page questionnaire listing a broad range of children's emotional and behavioral problems that reflects parents' impressions of their child's psychosocial functioning. The screen is intended to facilitate the recognition of emotional and behavioral problems so that appropriate interventions can be initiated as early as possible.
The PSC consists of 35 items that are rated as “Never” “Sometimes,” or “Often” present and scored 0, 1, and 2, respectively. The total score is calculated by adding together the score for each of the 35 items. Cutoff scores for pre-school and school-age children indicating clinical levels of dysfunction have been empirically derived using Receiver Operator Characteristic analyses in studies comparing the performance of the PSC to other validated questionnaires and clinicians' assessments of children's overall functioning (Jellinek, 1986; Jellinek et al., 1986; Little et al., 1994). Positive screens are those with scores above 27 for ages 6-18 and scores of 24 and higher for children ages 4 and 5. For the PSC-Y, the cutoff is 30 and higher and for the PSC-17, the cutoff score is 15. More detailed instructions on scoring the PSC can be found in the Scoring the PSC.
Factor analysis of the full set of 35 items has also led to the validation of three subscales for use in identification of attentional, internalizing, and externalizing problems. A description of the items in each of these scales and scoring instructions can also be found in Scoring the PSC.
The philosophy of routine psychosocial screening using the Pediatric Symptom Checklist is congruent with the evolving concept of a “medical home” for children, which is a key facet of the redesigned healthcare system that is being put into place in the US in 2012 (Deloitte Center for Health Solutions, 2008). The pediatric medical home is well described on the AAP website (http://pediatrics.aappublications.org/content/110/1/184.full.pdf). The concept of the medical home encourages a stronger focus on the integration of emotional and behavioral issues into routine pediatric care, especially through the earlier identification of and intervention for children who have or are at risk for emotional, social, or behavioral disorders.
The current focus on mental health as a key aspect of physical health builds on many efforts over the past decade. Early mental health screening was included as a named goal by the President's 2003 New Freedom Commission on Mental Health. Early Periodic Screening, Diagnosis, and Treatment (EPSDT), the regulations governing well child care for children with Medicaid health insurance, includes a clear requirement for routine psychosocial screening. The Surgeon General’s national health goals (Healthy People 2010) included the specific recommendation that pediatricians and other primary care physicians include routine screening for mental health problems as a part of primary care. In light of the growing recognition that mental health is a critical component of overall wellbeing and quality of life in children and adults, the American Academy of Pediatrics (AAP) recently issued a call for pediatricians to consider mental health during all well child visits using validated, reliable measures like the PSC (AAP, 2012). This recommendation followed the AAP’s endorsement of an expanded focus on psychosocial functioning through the publications of its Bright Futures and Bright Futures Mental Health guidebooks which date back more than two decades (http://brightfutures.aap.org/3rd_Edition_Guidelines_and_Pocket_Guide.html).
Because of the screen’s utility in facilitating the recognition of mental health problems, some investigators have recommended that the PSC be considered "basic office equipment" in pediatrics for several decades (Sturner, 1991). Others have urged that the PSC become a mandated part of all well-child visits in managed care settings or large programs like Medicaid EPSDT (Murphy et al., 1996; Pagano et al., 1996). Several states (e.g. Arizona, Massachusetts, Tennessee) now recommend the PSC or other brief questionnaires for psychosocial screening during EPSDT visits, and a number of HMO’s (Kaiser of Northern California, Neighborhood Health Plan of Massachusetts) use the PSC as a routine part of well-child visits. The PSC is also being used as a part of annual screenings in a variety of non-health care settings like Ventura County, California Head Start (Jellinek et al., 2005).
As of this writing, the PSC has been used in dozens of studies and is listed as a recommended screening instrument in reviews posted on the websites of at least a half dozen states, a number of school districts, and several children’s advocacy organizations including the Section of Developmental and Behavioral Pediatrics of the American Academy of Pediatrics and the Bazelon Center for Mental Health Law (Bazelon, 1997). In January 2011, the PSC received a provisional endorsement for possible use as a national standard of care from the National Quality Forum (http://www.qualityforum.org), one of the two main standard setting organizations in the US. More information on the widespread use of the PSC can be found in PSC Research.
A series of reviews conducted by the Bazelon Institute (Bazelon, 1997; Semansky et al., 2003) have found evidence that, although they are inconsistent in the rigor of their implementation and follow through, most states do require mental health screening as part of their EPSDT programs. In the Bazelon reviews, the PSC was found to be the most commonly recommended measure for general psychosocial screening for school-aged children. Other instruments are recommended for screening younger children or teenagers or to screen for specific problems such as substance use disorder or depression. The PSC is currently recommended for psychosocial screening in pediatrics on the websites of at least a half dozen states: Arizona (Pinal/Gila Long Term Care, 2007), Massachusetts (Massachusetts Behavioral Health Partnership, 2004), Minnesota (Minnesota Department of Health, 2007), North Carolina (North Carolina Department of Mental Health and Human Services, 2007), New York (New York State Office of Mental Health, 2006), and Tennessee (Tennessee Department of Mental Health and Developmental Disabilities, 2007).
As a result of expanded reimbursement policies by the state's major insurers, the practice of routine screening for psychosocial problems in pediatrics took two major steps forward in Massachusetts in recent years. First of all, the state’s largest insurers, including Blue Cross Blue Shield, now reimburse pediatricians for this kind of screening at rates ranging from $15 to $20 per screen (Massachusetts Chapter of the American Academy of Pediatrics, 2007). Similar policies and a reimbursement of about $10 are also mandated for patients with Medicaid health insurance (Goldberg, 2007).
Although the results of these new policies in Massachusetts have not been fully evaluated, a recently published study by Kuhlthau and colleagues (2011) demonstrated that a funded, court-ordered mandate to screen for mental health during Medicaid well-child visits in Massachusetts appears to have resulted in a significant increase in the number of screened children as well as the number of children found to be at risk for emotional or behavioral problems. Another interesting line of questioning is whether, as hoped for by expert opinion like Healthy People 2010, implementing routine psychosocial screening will have a measurable impact on children’s mental health or overall health and the costs associated with these conditions. This will likely be an area for fruitful research in the future.
In the meantime, it is clear that the PSC is one of the most frequently recommended instruments for children with both Medicaid and commercial health insurance and that the vast majority of studies over the past decade have shown the PSC’s usefulness as a marker for psychosocial dysfunction. The use of the PSC as a screener and its more recent application as an outcome measure for intervention studies, when added to the number of studies assessing the validity of the measure, provide a simple way of describing the types of studies which have been done with the PSC over the past decade. A review of each can be found in the section on PSC Research.
The under-detection of child mental health problems in pediatric practice has been well-documented (Costello, 1986; Costello, Edelbrock, & Costello, 1988; Navon et al., 2001). Psychosocial dysfunction has been found to contribute substantially to morbidity among children and adolescents (Prince, 2007) and early detection and treatment of psychosocial problems may lead to considerable health benefits (Reijneveld, 2006) including improved prognosis (Nelson et al., 2003). Screening for psychosocial dysfunction using a brief screening questionnaire among children and adolescents seeking routine medical care can greatly facilitate this process (Eisert, Sturner & Mabe 1991, Sturner 1991).
Over the past decade, the PSC has served as an easy-to-use tool that is broadly valid and reliable and can meet a growing array of therapeutic, research, and administrative assessment needs in a wide range of clinical, educational, and public health settings in the US and other countries. We expect continuing use of the PSC in pediatric settings now that it and other similar measures are mandated in Massachusetts and other states for all children enrolled in Medicaid. The fact that almost all major insurers are reimbursing pediatricians in this and other states for psychosocial screening is also expected to lead to increasing utilization of the PSC. Many offices use implementation of psychosocial and behavioral screening to review broader areas of communication with families. For example, having an introductory letter that explains the pediatrician’s policies and philosophy can be used to alert parents to the practice’s screening procedures, best books or AAP websites for developmental and psychosocial information, policies related to confidentiality, etc. As pediatricians start screening they might want to think through what information they have available in the office on key developmental and psychosocial topics.
Using the PSC
In the field of mental health, the PSC has been used as an outcome measure in an outpatient child psychiatry clinic and has demonstrated preliminary validity and utility for both global and subscale scores (Murphy et al., 2011; 2012). Educational uses of the PSC have expanded from a screen and a marker in some Head Start and school breakfast programs to one of the cornerstones of a national screening program that has grown to more than 50,000 students per year in Chile (JUNAEB, 2007). The nationwide Chilean program incorporates a comprehensive intervention and prevention program in conjunction with routine screening using the PSC in schools. Published results from Chile suggest that psychosocial problems as measured by the PSC have a strong and statistically significant relationship with standardized academic achievement test scores (Guzman et al., 2011).
With datasets in public health, psychiatric, and educational settings growing, we expect to work more extensively with subscales of the measure. For example, the Chilean group (JUNAEB, 2007) has added a subscale that measures resilience to the subscales of attention, conduct, and anxiety/depression problems that have been used in English language studies. Another paper assessing the mental health functioning of school children in Cambodia used these same subscales to examine the precise areas where children in an impoverished and socially stressed nation were experiencing dysfunction (Dany et al., 2012).
We also expect to use the PSC and its subscales more as a way to track functioning during pediatric or psychiatric treatment, educational initiatives, or public health interventions. In a large, hospital-based outpatient child psychiatry clinic at Massachusetts General Hospital, the PSC is currently used in an integrated system that inputs data directly into patient electronic medical records through the use of digital pens (Murphy et al., 2011; 2012). Using this system, PSC scores are obtained every three months and clinicians are required to use changes in these scores to guide treatment planning. The PSC is also one of the most commonly used measures in several different state-of-the-art software systems that physicians can use to assess and monitor changes in patients’ functioning and performance. In the CHADIS child health and development interactive system, the PSC is emailed to parents to complete before well child visits, filled out at home, and scored instantly so that any positive screens can become part of the follow up plan. In the CNS Vital Signs system of neurocognitive and behavioral assessment, the PSC can be entered on line, with scored reports emailed back instantaneously to the clinician, parent, or program. The Commonwealth of Massachusetts has adopted an innovative approach to reimbursement for the PSC and other brief psychosocial screens. By requiring a U1/U2 modifier to be included along with the CPT code of 96110, the data system is alerted to the presence of a positive screen. This in turn permits system wide monitoring to insure that children who are screened positive receive follow up visits.
In is important to keep in mind that the goal of the PSC is not rapid diagnosis or an express conduit to the use of medications. Instead, the PSC is a brief assessment of dysfunction in major areas of a child’s daily life. As an administrative or research tool, it is merely a snapshot. As a clinical measure, it is the first step in what should be a multistage assessment procedure. Positive screens with the PSC deserve careful, considerate, intelligent follow up by trained and trustworthy clinicians who will work with parents to understand each child within the totality of a unique individual, family, and community context and then hopefully find ways to provide more of the help that many parents of dysfunctional children so desperately desire.
