Utilizing the Pediatric Symptom Checklist

September 10, 2020

A good approach to knowing when a child needs referral for mental health evaluation, the Pediatric Symptom Checklist has evolved over the years to better screen children.

When I started my pediatric residency, I knew my long-term career goal was to be a child and adolescent psychiatrist. I very much appreciated that the pediatric residency built my core identity as a physician, capable of caring medically for children whether in an intensive care unit or in primary care. However, my natural bent was to always include the psychosocial aspects of care and to ask more psychologically oriented questions after the necessary medical information was gathered, for example, when admitting a child to the hospital. When I went to my primary care clinic, I, of course, completed all the usual screening and vital sign measures. Height, weight, urine screening for infection and diabetes, as well as traditional vital signs were done at every visit. In infants and toddlers, developmental issues such as sitting, walking, first words, and toilet training were well noted. However, through working in both an academic and community clinic setting, I was increasingly convinced that there were psychosocial concerns unaddressed and not recognized by any available screening approach.

Most supervising attendings would ask 1 or 2 questions about school or friendships that had a ‘hit or miss’ quality. The director of the clinic was wonderfully intuitive and almost magically sensed which children needed a mini-psychiatric review. However, at the time, there was no training requirement in behavioral pediatrics and even the rotations now instituted could not train someone to select children in a primary care setting without some screening mechanism. Overall, the recognition of emotional problems in pediatrics was highly variable, and the research conducted in the late 1970s indicated that the identification of emotional problems in pediatric primary care was well below expectations set by epidemiological studies.1 I wondered if there could be a short, valid screening questionnaire that could fit into the flow of a busy clinic and identify children in need of further pediatric evaluation and potential mental health referral.

I knew the time pressure and workflow in primary care practice. Any screening process, like a urine dipstick or blood pressure, had to be brief, take no more than 3 or 4 minutes to administer and score, and not clog up the waiting room that had been built to accommodate the typical flow of patients. The screen had to be understandable and readily accepted by parents and teenagers and, if possible, one form had to be applicable to a broad age range. The front desk had enough paper to deal with (electronic records were still 30 years in the future) that there could not be different screening forms by age, gender, or other demographic factors. Using the metaphor of a urine dipstick, the screening had to be simple with one form on one shelf. Given the economics of practice, the screen had to be free to administer and score and potentially be reimbursable like other routine procedures.

1. What issues or problems should a set of screening questions identify?

As a psychiatrist, I was trained to look for sets of symptoms that met criteria for a disorder—a system better suited to adults than to children, given the complexities of development and family considerations. Pediatricians were not familiar with lists of symptoms, with a certain number of symptoms needed for a diagnosis, independent of family or developmental history, and with a diagnostic result of more than one mental health diagnosis. A child diagnosed with major depression from the psychiatric perspective could be 11 or 16 years of age, could have a strong family history of depression suggesting a largely biological etiology, or could be trying to cope with divorcing parents, bullying at school, an alcoholic, abusive father, or a family’s food insecurity. Many pediatricians had no experience with this psychiatric diagnostic approach, were uncomfortable with one or more diagnoses not grounded in an etiology, and/or found it of limited use in communicating with parents or colleagues.

Rather than lists of symptoms, pediatricians start by asking how old is the child and how are they functioning with friends, school, activities, in family life? What is the status of the child’s mood and self-esteem? Given the strong reluctance to use the psychiatric symptom-based approach, to be broadly accepted, psychosocial screening in primary care would have to be based on understandable questions regarding daily functioning. A child’s daily functioning is an expression of their strengths and stressors. A child’s functioning is the common pathway for the influences of genetics, their psychological development, social determinants of health, coping abilities, and resilience. In the context of the epidemiology of childhood psychosocial issues, a screen will find 10%-15% of all 4-16-year-old children “positive,” meaning the pediatricians should include assessing the child further as part of the pediatric visit.

The questionnaire items reflect difficulties in psychosocial functioning with the goal of coming to a score that reflects risk versus non-risk. The first version of the screening tool had 35 questions for parents to rate their child’s problems as occurring “never,” “sometimes,” and “often.” Naming the screening questionnaire, “The Pediatric Symptom Checklist” (PSC) emphasized that a child’s psychosocial functioning was a core and routine part of pediatric healthcare. The PSC was freely available with no charge for the tool, its use, or scoring. More than a decade after initial validation, some colleagues found that groups of questions on the PSC clustered together and could reliably identify risk in 3 different domains: externalizing, internalizing, and attention problems in a shorter 17-item format of the PSC.2,3

2. Who should answer the questions?

Generally, a parent or legal guardian brings the child for the pediatric visit and is typically the person in the best position to assess the child’s functioning. The questionnaire reflects a parents’ perceptions and when considering the psychosocial functioning of a child, a parent is more like the umpire in a baseball game. A ball thrown by the pitcher is defined as a ball or strike by the umpire, and once defined, enters history as what the umpire indicated. Is a child more often alone, having fun, or not listening to rules? There are no objective counts, only a parents’ sense of the situation and that is why “often” scores are so relevant. The major area where parents’ perception is limited is with teenagers, when their thoughts are often private, and a related depressive mood may be hidden. A youth-completed version of the PSC has been developed and other instruments specific to adolescent depression such as the patient health questionnaire (PHQ-9 )are also available.

3. What is the clinical path of a primary care pediatrician if a screen is “positive”?

The goals for the clinician are to assess if the screen is a true positive (similarly to other positive screens, eg, repeating a higher than expected blood pressure), and, if deemed valid, assessing the level of severity and next steps. Questions answered “often” are a good starting point for the pediatrician to solicit the parent’s understanding, and to explore the impact of the behaviors on the child’s and family’s functioning. The next step is to have the pediatrician ask questions about other areas of functioning (school, friends, activities, family, and mood). Depending on these answers, it may be relevant to ask about family violence, any mental health treatment, family history of emotional disorders, and safety concerns (access to guns or dangerous adult medications). Usually, in about 15 minutes, pediatricians get a sense of whether this is a true positive, the general nature of the issue and the severity of impairment or suffering. Next steps might be to offer counseling, schedule a follow-up (“watchful waiting”), or refer to a mental health consultation. Repeat PSCs can be given at the appropriate interval to monitor watchful waiting or get some feedback on the course of treatment post referral. The PSC more than doubled both the recognition and referral rate for psychosocial dysfunction (See Figure).

Since its initial creation, over 35 years of research on the PSC in more than 200 studies has shown its validity and reliability in a wide range of settings,2 demonstrated that it is understood and well-accepted by parents and clinicians,4-7 is sensitive to the impact of social determinants of health and poverty on mental health,4,5,8 can be shortened from a 35- to a 17-item version, can be used in both a parent- and youngster-reported format,9-11 and that regular use of the PSC is associated with an increase in mental health treatment.12-14 The PSC is also used in specialty pediatric and mental health clinics, schools, Head Start, state agencies, and online.2

In Massachusetts, the PSC was one of a handful of recommended screening questionnaires mandated by a Federal Court as part of a remedy to broaden mental health services for children with Medicaid.15-17 The PSC has been endorsed by the Massachusetts and California Medicaid programs, the American Academy of Pediatrics, and the National Quality Forum, both for overall screening and for screening adolescents for depression using its internalizing scale.2 The PSC is now included in many if not most US electronic medical record systems (EMR) including two of the most widely used (EPIC and Centricity).

Studies of the PSC in an EMR indicate that 70%-90% of children in large systems can be screened routinely, that pediatricians document their discussion of PSC scores in medical records, generally selecting the higher scoring children for mental health referral. The screen is now a routine feature of the visit and increases referrals for mental health services.7

Many questions, however, still remain unanswered: Which children benefit the most from early recognition (those with the highest scores or those with lower levels of risk)? Can the PSC be used to track progress in treatment or highlight the need for more intensive treatment? What is the natural history of an individual’s scores over a decade or more of childhood and adolescence, how should outcomes in functioning be measured, and can the PSC be used more effectively to identify impending adolescent risk taking and suicidal behavior? The PSC is now widely used and is a major bridge between pediatric and mental health care. However, with the burden of mental health problems rising, especially during and post COVID, the bridge should be busier, better resourced, and refined by future research.
