Abstract
Objective:
To identify the percentage of 4–17 year olds with mental disorders in Australia who attended health professionals for single or repeat visits to get help for emotional and behavioural problems during a 12-month period. To identify factors associated with single and repeat visits, and the average length of time between visits. To compare the number of parent-reported visits with visits recorded in the Medicare Benefits Schedule.
Method:
The study used data from the national survey of the mental health and wellbeing of 4–17 year olds conducted in 2013–2014 (
Results:
Parents reported that 51.1% of 4–17 year olds with mental disorders had attended a health professional during the previous 12 months. However, 13.6% of these children had attended on only a single occasion, most commonly with a general practitioner. With the exception of occupational therapists, 2–4 visits was the most common number of repeat visits. Children with comorbid disorders and severe functional impairment and those aged 12–17 years were more likely to have repeat visits. Among those with linked Medicare Benefits Schedule data, more children were reported by parents to have attended Medicare Benefits Schedule-funded health professionals (47.9%) than were recorded in Medicare Benefits Schedule data (38.0%).
Conclusion:
The typical number of visits to health professionals by children with mental disorders during a 12-month period is relatively small. Furthermore, parent-reports may overestimate the number of visits during this time. It seems unlikely that current patterns of attendance are of sufficient duration and frequency to allow full implementation of evidence-based treatment programmes for child and adolescent mental disorders.
Introduction
Child and adolescent mental disorders have a significant adverse impact on children, families and the community (for brevity, the term ‘children’ will be used to describe children and adolescents in this manuscript) (Institute for Health Metrics and Evaluation (IHME), 2017; Kessler et al., 2005; Knapp et al., 2011). To successfully address this problem at a population level, it is essential that universal, targeted and clinical services are employed in the most effective manner possible. This is particularly important for services provided by health professionals because such services are expensive to provide and often relatively scarce.
Accurate information about the proportion of children with mental disorders in the general community who have contact with health professionals and the nature of this contact is an essential prerequisite to determine the effectiveness of clinical interventions at a population level. While more recent studies have reported that a higher proportion of children with mental disorders in the community have contact with health professionals, a significant limitation of almost all previous studies is lack of information about the extent to which this contact is comprised of a single visit or includes sufficient ongoing contact to allow delivery of evidence-based treatment programmes (Farmer et al., 1999; Green et al., 2013; Johnson et al., 2016). This is an important issue because interventions recommended in treatment guidelines for the management of childhood mental disorders such as major depressive disorder (MDD), attention-deficit hyperactivity disorder (ADHD), conduct disorder (CD) or anxiety disorders (AD) uniformly require multiple contacts with service providers (National Institute for Health and Care Excellence, 2016, 2017a, 2017b). In contrast, there is no evidence of which the authors are aware that demonstrates a single visit with a health professional is sufficient to effectively treat these disorders. A further limitation of previous studies is lack of information about the frequency of visits (e.g. weekly, monthly or annually). This is a significant omission because of the potential adverse impact that long gaps between visits can have on the quality of therapeutic relationships required for effective delivery of treatment programmes.
Four previous studies have reported the number or frequency of service attendances by children with mental disorders in population samples (Farmer et al., 1999; Lawrence et al., 2015; Meltzer et al., 2000; Merikangas et al., 2011). In Australia, Lawrence et al. (2015) reported that over a 12-month period, 41.7% of visits to general practitioners, 31.7% to paediatricians, 21.3% to psychiatrists and 17.2% to psychologists by children with mental disorders seeking help for emotional and behavioural problems consisted of single visits (Lawrence et al., 2015). However, the extent to which these children had also attended other health professionals on repeated occasions during this time was not reported. This makes it difficult to interpret the meaning of the results as access to psychiatrists and paediatricians, and commonly psychologists, for the treatment of mental health problems requires a referral from a general practitioner in Australia. As such, a single visit with a general practitioner may have been for the purpose of obtaining a referral to a specialist. It is also possible that a child who had a single consultation with one health professional may have attended another on several occasions.
In Great Britain, Meltzer et al. (2000) reported that over a 12-month period 25% of 5–15 year olds with a mental disorder had attended their general practitioner >2 times compared to 13% of children without a disorder. However, the authors indicated that these visits could be for any health problem rather than specifically for management of mental health problems. In the United States, in a 1-year prospective study of 1007 children aged 9, 11 or 13 years at baseline, approximately 30% of those who used a health or education service to address a mental health problem during a 3-month period continued to use services during a subsequent 3-month period. However, less than 10% used services during multiple 3-month periods across the year of the study (Farmer et al., 1999). For mental health services, the most common pattern was 1–2 visits over a 3-month period. Using data from the National Comorbidity Survey, Merikangas et al. (2011) reported that 68% of 13–18 year olds with mental disorders in the United States had less than six ‘service contacts’ (p. 38) across their life time. The authors described this as a very small number of lifetime visits for young people with disorders typically associated with high service needs.
This study had three main aims: (1) to identify the percentage of 4–17 year olds with mental disorders in Australia who attended health professionals for single or repeat visits during a 12-month period, (2) to identify factors associated with single and repeat visits and (3) to identify the typical length of time between repeat visits. To assess the accuracy of parent-reported service use, for 13–17 year olds we also compared the number of parent-reported visits to health professionals, visits recorded in the Medicare Benefits Schedule (MBS) and self-reported visits over the 12-month period.
Methods
Participants
The participants were children identified as having a mental disorder in the second Australian Child and Adolescent Survey of Mental Health and Wellbeing (Lawrence et al., 2015). The survey was conducted during 2013–2014 and the dataset is available to research professionals (Zubrick et al., 2014). Participants were a nationally representative sample of 6310 4–17 year olds and their parents/carers (for brevity referred to as parents; response rate = 55%). Young people aged 11–17 years (89% of those eligible,
Participation in the survey was voluntary and all participants gave written consent to participate. The research protocol for the study was approved by the Australian Government Department of Health Human Research Ethics Committee and The University of Western Australia Human Research Ethics Committee.
Measures
Mental disorders
Mental disorders were assessed using the Diagnostic Interview Schedule for Children–Version IV (DISC-IV) completed by parents (Fisher et al., 1993; Shaffer et al., 2000). The DISC-IV implements the criteria for mental disorders set out in the
Functional impairment
Detailed information about the measure used to assess children’s level of functional impairment is available in a technical report (Zubrick et al., 2015). In brief, the measure consists of 17 items that rate the extent to which AD, MDD, ADHD or CD adversely affect children’s schooling, friendships, family and the children themselves. For the purpose of this study, we used tertiles from the total functional impairment score to categorise children into one of three impairment groups described as mild, moderate and severe impairment. If a child had an impairment score for more than one diagnosis, the most severe level of functional impairment was utilised in this study.
Parental psychological distress
The Kessler-6 (K6) scale was used to assess parental psychological distress in the past 4 weeks. For the purpose of this study, recommended cut-off scores were used to categorise parents into one of two distress levels described as ‘high’ and ‘normal’ (Furukawa et al., 2003).
Family functioning
A short version of the General Functioning Scale of the Family Assessment Device completed by parents was used to assess family functioning. Recommended cut-off scores were used to categorise families into one of two groups described as ‘unhealthy’ and ‘healthy’ (Boterhoven de Haan et al., 2015).
Parent-reported service use
Parents were asked whether their child had attended a general practitioner, paediatrician, psychologist, psychiatrist and/or another health professional (i.e. social worker, occupational therapist, counsellor/family therapist) to get help for emotional or behavioural problems during the last 12 months. Parents who responded positively were asked for the location of this service (e.g. ‘doctor’s rooms or other private practice’, Child and Adolescent Mental Health Service and hospital emergency). They were also asked whether their child had attended 1, 2–4, 5–9 or ⩾10 times during the 12 months. Children aged 13–17 years (
For the purpose of this study, the number of visits with health professionals during the 12 months before the survey were categorised as follows:

Sociodemographics
Family type, household income and household location (metropolitan vs non-metropolitan) were collected using the Australian Bureau of Statistics standard formats (Australian Bureau of Statistics, 2014).
Statistical analyses
Statistical analyses used parent responses to the national survey to identify the percentage of children with mental disorders who had single and/or repeat visits with health professionals during the 12 months prior to the survey. In all the analyses, survey data were weighted to represent the full Australian population of 4–17 year olds and to adjust for patterns of non-response. Visits to nurses or health professionals whose professional discipline was unknown were not included in these analyses.
Logistic regression was then used to examine the strength of the relationship between number of visits (single and repeated), and child and family demographic characteristics, children’s level of functional impairment, family functioning, parental distress and the presence of comorbid disorders. All analyses were conducted using the Stata software ‘svy’ procedure to account for the clustered nature of the sample design and use of survey weights (StataCorp, 2017). In these analyses, two sets of logistic regression models were fitted. Initially bivariable logistic models were used to assess the strength of the relationship between service use and each predictor variable. Subsequently, a single multivariable model was produced in which all the predictor variables were included in the model to identify the strength of the relationship between service use and each predictor variable, after adjusting for the effect of the other predictor variables. The analyses using parent-reported visits were all repeated using MBS data.
Throughout the presentation of results, the percentages are weighted to represent the full Australian population of 4–17 year olds while the number of participants shown is the number in the survey sample.

As compared to those with no visits to health professionals, a higher percentage of children who had ⩾2 visits were 12–17 year olds, had severe functional impairment, a comorbid disorder and lived in lower income and single-parent families (Table 3). In the multivariable logistic regression models, children with ⩾2 visits were 6.1 times more likely to have severe functional impairment, 2.0 times as likely to have a comorbid disorder and 1.5 times more likely to be in the 12–17 year age group than children with no visits to health professionals (Table 4).
Time between visits to health professionals
Information about the time between visits for children with ⩾2 visits was available for 181 of the children with linked MBS data (Table 5). This showed that repeat visits with general practitioners had a median gap of 75 days (IQR = 33–153 days) (Table 5). The median gap for psychologists was 14 days (IQR = 9–28 days), for psychiatrists it was 31 days (IQR = 15–54 days) and for paediatricians it was 70 days (IQR = 29–125 days).

Discussion
Several findings are evident from this study. First, parents reported that 51.1% of the 4–17 year olds with mental disorders in the study had contact with a health professional during the 12 months prior to the national survey. However, 13.6% of these contacts were for a single visit, most commonly with a general practitioner. Single visits were also relatively common with other health professionals ranging from 16.1% of visits with psychologists to 30.6% of visits with paediatricians. With the exception of occupational therapists, 2–4 visits was the most common number of visits with each of the health professionals over the 12 months assessed in this study.
Second, none of the demographic and psychosocial factors examined in the study had a strong relationship with single visits. In this area, the absence of a relationship between family functioning and service use is consistent with results of previous studies (Ryan et al., 2015). However, as compared to children with no visits to health professionals, children with ⩾2 visits were six times more likely to have severe functional impairment, twice as likely to have comorbid disorders and 1.5 times more likely to be aged 12–17 years old.
Third, there was a sizable gap in time between visits with most health professionals. For example, the median number of days between appointments with psychiatrists was 31 days and for paediatricians it was 70 days. For psychologists, the median number of days between visits was 14 days. For all these health professionals, there was also a very wide range in the length of time between visits.
Finally, comparisons of parent-reports and MBS records suggest that parent-reports may overestimate the number of 13–17 year olds who attend health professionals for help with mental health problems. They also suggest that parent-reports may overestimate the number of repeat visits 13–17 year olds have with health professionals.
The results suggest that although the number of children having contact with health professionals appears to have increased in Australia over the last 20 years (Lawrence et al., 2015; Sawyer et al., 2000), the number of repeat visits to health professionals remains small. Saloner et al. (2014) have suggested that ⩾4 visits are required for minimally adequate treatment for mental disorders involving a psychotropic medication and ⩾8 visits for treatment without medication. While it was not possible to identify the nature of children’s treatment in this study, it is notable that among the children with mental disorders, less than 30% (
Relatively little is known about how long children with mental disorders stay enrolled in services and what influences ongoing use of services. The results from this study suggest that somewhat different factors influence single versus repeat visits with health professionals. Specifically, the characteristics of those with single visits were not significantly different from those with no visits. However, those with ⩾2 visits had higher levels of functional impairment and comorbidity and were also more commonly older than those with no visits. This is consistent with one of the few previous studies to examine this issue which reported that higher symptom levels among children, greater parental psychopathology and higher parent education were associated with persisting service use over a 12-month period (Farmer et al., 1999). In this study, level of functional impairment and presence of comorbid disorders had a stronger association with participation in ongoing treatment than other demographic characteristics such as family income and family structure. This suggests that it is the clinical characteristics of children’s problems, rather than their demographic characteristics that are playing the key role in decisions about the provision of ongoing care and support.
The low percentage of children with mental disorders receiving minimally adequate treatment is similar to that reported in a recent national study of adults with affective and/or anxiety disorders in Australia where only 16% of participants were receiving minimally adequate treatment, defined in a similar way to this study (Harris et al., 2015; Saloner et al., 2014). This frequent pattern of inadequate care cannot be identified in studies where level of service use is described using a dichotomous indicator that simply records service contact versus no contact. However, it is an important issue because epidemiological studies conducted during the last decade have demonstrated that the prevalence of child and adult mental disorders is not decreasing in Australia and other industrialised countries (Collishaw, 2015; Collishaw et al., 2010; Jorm et al., 2017; Lawrence et al., 2015; Sawyer et al., 2000). Jorm et al. (2017) have suggested that a potential reason for the lack of change in prevalence of mental disorders among adults is that much of the treatment provided may fail to meet minimal standards of clinical practice guidelines. The results from this study suggest that similar problems may exist with much of the treatment provided to children with mental disorders.
Problems with service systems, health practitioner issues, and parental knowledge and attitudes all have the potential to adversely affect the dose of treatment received by children with mental disorders. Service system issues include problems with service access, the cost of services (including incidental costs such as travel costs, lost work time and costs of child care for siblings) and lack of availability of ongoing appointments (Lawrence et al., 2015; Sawyer et al., 2000). Health care provider issues include failure to deliver evidence-based treatments, variations in clinical practice and insufficient time or remuneration for delivery of evidence-based treatments. Parent issues include uncertainty about whether children need help, a preference to handle problems themselves and difficulties getting children to attend appointments (Lawrence et al., 2015; RCH National Child Health Poll, 2017). It is notable that in both Australian national surveys, practical problems of this kind were more commonly identified as barriers than issues related to stigma (Lawrence et al., 2015; Sawyer et al., 2000). This suggests that while it is important to continue addressing issues of stigma, doing this without addressing the significant practical problems experienced by parents seeking help for children with mental disorders will not improve treatment outcomes.
Finally, the results highlight the value for population-level service planning of combining information collected in epidemiological studies with that available in electronic health records, such as MBS. As noted by Angus (2015), electronic health records have the advantages of being inexpensive to access, specific to individuals and also descriptive of entire populations. The value of this information is evident in this where it appears that parents may overestimate the number of visits children with mental disorders have with health professionals as compared to data collected contemporaneously at the time of the visit. It is possible that this occurred because parents were reporting visits to health professionals funded through private health insurance schemes or for services based in schools or in public health services. However, when comparisons were limited to services provided in doctor’s rooms or other private practice settings, the gap remained.
Limitations
Strengths of this study include its national scope, the quality of its sampling methods, and its use of well-established diagnostic criteria and methods. However, it also has some limitations. These include a response rate of 55% and diagnostic information limited to parent-report. Extensive checking showed that the participants were highly representative of the national population of 4–17 year olds (Hafekost et al., 2016; Lawrence et al., 2015). However, it is possible that inclusion of children who did not participate in the survey may have changed population estimates. It is also possible that additional information from other informants such as children or teachers may have altered the proportion of children who were considered to meet the criteria for one or more of the disorders in the study. Finally, it was beyond the scope of this study to investigate use of school-based services, but previous work has shown that these are also an important source of support for children with mental disorders (Lawrence et al., 2015).
Conclusion
This study demonstrates that while slightly more than 50% of children with mental disorders have contact with health professionals during a 12-month period, many of these children will have insufficient visits to allow for the delivery of interventions that meet minimum recommended clinical practice guidelines (National Institute for Health and Care Excellence, 2016, 2017a, 2017b).
The results highlight an urgent need to better understand why so few children with mental disorders receive minimally adequate care. There is also a continuing need to develop, implement and evaluate new interventions delivered in routine clinical practice that can benefit larger numbers of children than is possible with traditional face-to-face treatment approaches. Achieving these goals will require changes to service systems to optimise access to care, upskilling of existing workforces in evidence-based mental health care and greater use of Internet-based services to reach larger numbers of children with disorders. It will also require ongoing monitoring and feedback to health care professionals about both the care they provide and its effectiveness in providing help for children with mental disorders. Finally, success in these areas will only be achieved by working in partnership with parents and children to help facilitate early recognition of mental health problems and reduction of practical barriers that currently impede effective engagement with mental health systems of care.
