Abstract

The prevalence of mental health problems, some of which seem to be occurring among younger cohorts, leads

researchers and policy-makers to search for practical solutions to reduce the burden of suffering on children and their

families, and the costs to society both immediate and long term. Numerous programs are in place to reduce or alleviate

problem behaviour or disorders and/or assist positive youth development. Evaluated results are dispersed throughout

the literature. To assess findings and determine common elements of effective children’s services, a literature search was

undertaken for evidence-based evaluations of non-clinical programs for school-age children. Prescriptive comments aim

to inform service-providers, policy-makers and families about best practices for effective services such as: early, long-

term intervention including reinforcement, follow-up and an ecological focus with family and community sector

involvement; consistent adult staffing; and interactive, non-didactic programming adapted to gender, age and cultural

needs. Gaps are identified in our understanding of efficiencies that result from effective programs. Policy implications

include the need to develop strategies for intersectoral interventions, including: new financing arrangements to

encourage (not penalize) interagency cooperation and, to ensure services reach appropriate segments of the population;

replication of best practices; and publicizing information about benefits and cost savings. In many jurisdictions

legislative changes could create incentives for services to collaborate on service delivery. Joint decision-making would

require intersectoral governance, pooling of some funding, and policy changes to retain savings at the local level.

Savings could finance expansion of services for additional youth.

Introduction

This paper provides an overview, drawn from reviews,

of evidence on the effectiveness and efficiency of mental

health services for school-aged children, and addresses

the policy implications of its findings. Evidence of

effectiveness compares outcomes for children (and

youth) receiving and not receiving services; efficiency,

in this paper, considers the cost of providing services

compared to the cost to society of not providing such

services. The study included both universal population-

based services (provided to all children) and early

intervention population-based services (provided only

to at-risk children).

There is a high prevalence of mental health problems

in children (20–30%) (Stephens, Dulberg, & Joubert,

1999) and many of them have multiple problems (Byrne

et al., 2002), which are inadequately treated or

undetected (Offord et al., 1999). Numerous publicly

funded but uncoordinated agencies in the health,

education, social services, recreation and corrections

sectors provide various types of care for children, yet

many still lack the appropriate care that would be

informed by a more comprehensive view of their

problems. Untreated problems in children is costly in

human and fiscal terms, for themselves, their families

and the wider society (Offord, Boyle, & Racine,

1992) (such as, the costs of lost potential, observed in

school dropout rates, unemployment, welfare rates and

crime).

The following questions, suggested by Knapp (1997),

will be used to address the issues:

1. What outcomes are the interventions or services

trying to achieve, a reduction of problems or

promotion of competencies?

2. How? With what mix of services: prevention,

enhancement of positive factors or treatment of

negative factors?

3. For whom is the service intended, for what age or

other characteristics?

4. Where is it delivered: at school, within the family,

primary care, the community or in some combina-

tion?

5. Why and how is the program expected to help? Is the

strategy specialized, or part of a coordinated or

integrated plan?

6. What results are shown?

This paper sets out to analyse the evidence, focussing

on reviews of the literature and seminal studies which

address the above questions.

Correlates of child health outcomes and conceptual

framework

Considerable research has confirmed associations

between developmental, emotional and behavioural

disorders and a wide array of interrelated influences on

the individual, direct and indirect, biological and

contextual (Greenberg, Domitrovich, & Bumbarger,

2001). Contextual factors include influences on a child

within the family, neighbourhood, school and commu-

nity (Offord & Lipman, 1996). Inherited traits and pre-

dispositions, physical health, cultural norms, parental

education, parenting style, income and family stability,

among other factors—all are potentially positive or

negative influences. The positive relationship between

emotional/behavioural problems and family socioeco-

nomic status, e.g., is well established in population

studies (Marmot, Ryff, Bumpass, Shipley, & Marks,

1997). Risk may include specific biological or environ-

mental insults that produce neurological or psychologi-

cal defects, but, as well, may involve the presence or

absence of resources and opportunities that more subtly

shape developmental pathways.

In as much as they provide a child with resources to

cope with or buffer negative stressors and thrive despite

deficits, internal and external factors are protective of

mental health. Both risk and protective factors interact

to help determine child development (Benson & Saito,

1999). Exposure to accumulating risk factors increases

the likelihood of mental health, developmental or

behavioural problems (Offord et al., 1999), yet protec-

tive factors lessen the effect of risk factors as long as

some degree of balance is maintained (Catalano,

Berglund, Ryan, Lonczak, & Hawkins, 1999).

A strong current has developed in the United States

and elsewhere over the past 20 years for services to

strengthen this mental ‘immune system’ in children,

termed resilience, accompanied by a sizable literature. A

resilience checklist by Grotberg (1998) identifies char-

acteristics of resilience across various ages and culture.

Resilience theory suggests that all children can benefit

from preparation to help them respond to adversity with

effective, healthy strategies and coping mechanisms

(Catalano et al., 1999). Being risk free is not the same

as being prepared (Greenberg et al., 2001). One is

prepared, despite risks, when one can say, to paraphrase

Grotberg, that one has caring people for support and

guidance, confidence in one’s own self-worth, and good

coping skills. Recreational, educational or social pro-

grams may aid healthy child development through risk

factor reduction or positive youth development. Com-

petence, engagement, support, identity and efficacy are

frequently included as mechanisms. Programs may also

address specific behaviours (e.g., substance abuse) or

treat children’s mental health disorders and symptoms

(e.g., attention-deficit hyperactivity). Whereas the for-

mer are likely universal or early intervention, the latter

are more likely targeted or clinical interventions (i.e.,

limited to children exhibiting symptoms or with a

diagnosed disorder).

Since more attention has been given to pre-school

research (Zoritch, Roberts, & Oakley, 1998), we

focussed primarily on reviews of universal and early

intervention services for older children. Programs

providing clinical services were excluded.

chrane; Centre for Reviews and Dissemination, UK;

Universit!e de Qu!ebec !a Montr!eal (UQAM); Health

Canada (2000), international health research organiza-

tions, and related links. Restricting reviews to English-

only articles may, unfortunately, have omitted some

useful international findings. Reference Manager (data

management software) provided detailed lists from 1714

studies, which produced additional sources from refer-

ences. Research centres, funding agencies, government

departments, and health service agencies recommended

unpublished material.

Content and quality were the primary selection

criteria for investigators. Evaluation methods were

critically appraised using parameters suggested in

several references (Oxman, 1994). Economic evaluations

had to address program goals, breadth of focus, timing

and intensity, venues, audience, evaluation rigour and

connections to other programs and the community.

Investigators concentrated their attention on ‘multi-

disciplinary’ programs that involved several service

sectors and/or professions, where possible, and used

only reviews of randomized controlled trials or quasi-

experimental comparison groups to increase reliability.

Where articles included a mix of experimental and non-

experimental studies, those meeting the criteria were

assessed first to assemble key conclusions. Non-experi-

mental studies such as descriptive narrative literature

and informed opinion were later considered for context.

The quality of review articles was assessed using

suggestions from relevant literature (Oxman, Cook, &

Guyatt, 1994; Guyatt et al., 2000). A review had to:

address a focussed question; have effective, appropriate

selection methods for relevant articles; appraise study

validity; give sufficient methodology to reproduce

assessments; provide consistent, complete and precise

results; and consider results in terms of importance,

applicability, benefits and limitations. Table 1 rates the

quality of the 23 reviews summarized.

Results

Tables 2–7 provide a study-by-study summary of

findings. Here we discuss a number of patterns and

characteristics common to the early intervention pro-

grams, and to both early intervention and universal

programs.

Reviews discussed efforts to reduce deficiencies

related to depression, anxiety, externalizing/internalizing

or other psychological/social problems (Table 2),

reductions in risky behaviours (Table 3), outcomes to

increase competence and resilience through various

protective strategies (Table 4) or programs with a

combination of both outcome strategies (Table 5). Some

reviews contained school-based programs to promote

positive behaviours and prevent psychosocial problems

(Table 6); others contained community-based programs

with similar aims (Table 7).

Although universal or early intervention programs to

develop protective factors (generally by increasing

competence or skills), are more effective (Tables 4

and 5) than programs to reduce existing negative behavi-

ours (Tables 2 and 3) (Greenberg Domitrovich, &

Bumbarger, 1999); nevertheless, program effectiveness

can vary by age, gender and ethnicity of children.

Younger children, either pre-school age or in early

grades, benefit more than older children (Zoritch et al.,

1998) but programs for some older children are also

effective (Ploeg, Ciliska, & Brunton, 2000). Programs

to address a specific problem or problems, which are

sensitive to cultural or gender-based differences

(Thomas et al., 1999), have greater effect than broad,

unfocussed interventions. For example, because, adoles-

cent boys and girls have responded differently to suicide

prevention programs, gender-focussed programs are

advisable. Similarly, programs for aboriginal children

have more positive results when they use traditional

knowledge and modes, are based on community

initiatives, and involve both family and community

(Kirmayer, Boothroyd, Laliberte, & Simpson, 1999).

Programming that has multiple, integrated elements

involving more than the single domain of family, school

or community, is more likely to have positive results

than single focus, single domain interventions (Tables 4

and 5). This characteristic was shared by initiatives to

create competence by skills acquisition (Catalano et al.,

1999), to address clustered risky behaviours (Dowswell,

Towner, Simpson, & Jarvis, 1996), to reduce risk and, to

some extent, to change established behaviour (Lister-

Sharp, Chapman, Stewart-Brown, & Sowden, 1999).

Theoretical bases of programming seem effective

when appropriate for the type of intervention (Con-

tento, Balch, Bronner, & Lythe, 1995). For example,

positive outcomes associated with skill acquisition were

enhanced by interventions using interactive learning

based on social learning theory, developmental social

norms, social influence and social reinforcement (Lister-

Sharp et al., 1999), on social pressure modelling and on

skill rehearsal (Tables 4 and 5) (DiCenso, Guyatt, &

Willan, 1999). Effect sizes decreased over time for

knowledge and skills acquisition (Rispens, Aleman, &

Goudena, 1997) and behaviour reduction (Thomas et al.,

1999), suggesting the need for periodic follow-up and

reinforcement of positive interventions. An exception,

Marcotte (1997), found an increased effect size over time

(Table 2) among programs to treat depression in

adolescents by cognitive behavioural change. This may

derive from the intervention or from unrelated factors

such as the natural progression of milder disorders.

Certain methods of program delivery (Table 6) are

associated with lower effectiveness. Fear-inducing

tactics such as ‘shock incarceration’ programs (Table 5)

seem ineffective (Greenwood, Model, Rydell, & Chiesa,

2000). Programs that deliver information only, and in a

didactic mode, appear to be less effective (Hertzman &

Wiens, 1996) than interactive activities impacting both

school and family. Long-term programming, from

several months to years, is shown to be more effective

than short, intensive initiatives (Heneghan, Horwitz, &

Leventhal, 1996). Early interventions for children at risk

(Durlak & Wells, 1997) or in the early stages of

disordered behaviour can also be effective (Greenwood

et al., 2000). Certain behaviours and attitudes proved

more resistant to change (e.g., substance misuse, unsafe

sex and oral hygiene (Thomas et al., 1999).

The continuing presence of appropriate adult staff

(Tilford, Delaney, & Vogels, 1998), and mentoring or a

stable relationship with a successful adult, were im-

portant aspects of program delivery. The latter pro-

motes positive social/emotional development, academic

achievement, and reduces disordered behaviour (Gross-

man & Tierney, 1998). Peer mentoring effectively

promotes favourable academic and social behaviour in

early intervention programs (Kalfus, 1984) and social

skills in children with behaviour disorders (Mathur &

Rutherford, 1991), but is less reliable for general

competencies and skill maintenance (Odom & Strain,

1984).

Almost every review dealt with services that were all

or, in part, within a school venue. Easily accessible on-

site, school-based services encourage continuing partici-

pation, an important element of an intervention, yet risk

breaches of confidentiality and labelling of participants.

Programs operated out of community centres can

provide confidentiality and serve a larger catchment

area, but reach a smaller proportion of area children

than school-based programming. When children are

already exhibiting symptoms, the inclusion of families in

community-centre-based interventions is an important

factor for success (Greenwood et al., 2000). A compre-

hensive solution would include services in both venues.

Educational and fiscal policies that limit the use of

schools for non-curricular activities are current chal-

lenges to such a solution.

Though a lack of data about cost–benefits in the

reviews renders economic evaluation difficult, other

findings in the policy literature (Browne et al., 1999;

Browne, Byrne, Roberts, Gafni, & Whittaker, 2001)

identify cost savings from preventive children’s health

initiatives.

Discussion

The findings have numerous implications for further

research and policy direction in the child mental health

field. Reviewers noted some inconsistent methodology

and deficiencies in study design, intervention strategies

and reporting, necessitating caution toward some results

(Breton et al., 1998). However, the number of common

findings from so many differing samples and interven-

tions lends credence to their reliability.

The benefits of creating programs around an ecolo-

gical approach to children’s services are echoed in the

broader literature (US Public Health Service, 2000). It

seems clear that effective services for school-aged

children should address their individual needs and

involve the multiple domains and support systems in

their lives. The evidence calls for universal services to

bolster protective factors and for tailored, long-term,

timely interventions for high-risk children, an approach

consistent with other recent findings (Board on Chil-

dren, Youth and Families, 2002; Offord et al., 1999). An

underlying thread is that effective children’s services,

and agencies, should address the whole child rather than

focussing only on a single problem behaviour, since

children often have a cluster of emotional/behavioural

problems, interrelated with one another and with

external factors. Research is still needed to prove the

benefits of specific innovative, intersectoral combina-

tions of health, social, educational and recreational

programs to promote competence in the face of

deficiencies and risks, assist behavioural change, and

affect the prognosis of child/youth behaviour problems.

We need to determine the accessibility and population

coverage of effective, universal and early intervention

strategies by age, gender and culture and evaluate

policies to encourage their adoption and support.

Comprehensiveness of research into interventions can

be assessed using the framework proposed in Fig. 1.

Furthermore, we need to understand what organiza-

tional and financial barriers impede the implementation

of ecological, community-wide, universal and early

intervention strategies, study best practices and normal-

ize inclusion of cost effectiveness as a part of evaluation.

Such evidence would then inform policy changes to

facilitate intersectoral cooperation and appropriate

long-term funding. Transparent public decision-making

would rely on the dissemination of evidence about

effective interventions and upon mechanisms to encou-

rage replication of proven effective services.

With some notable exceptions (Knapp, 1997), re-

search overlooks organizational and financial govern-

ance and policy mechanisms needed to foster integration

within and across differently financed services. Few

studies evaluate whether universal and early intervention

initiatives can save the public sector money. However,

that aspect is receiving more recent attention (Browne

et al., 2001).

Current programs developed to influence children’s

development and mental health are generally uncon-

nected and certainly unintegrated. Many programs

initiated locally to meet perceptions of community need

compete for funding and community support. Deter-

mining program effectiveness is only a beginning.

Given service delivery problems, some children are

undoubtedly not receiving potentially beneficial pro-

grams. Jones and colleagues make the point that

‘universally available’ is not synonymous with ‘equal

access’ or ‘equal participation’ (Jones, 1992). Policy

initiatives need to be developed to ensure sufficient

funding and promote delivery of effective programs to

appropriate children. Program planning should also

consider meeting intersectoral needs, providing trans-

portation if necessary, or other tangible aid to families,

to reduce program attrition or bolster intervention

effectiveness.

A strategy of risk factor reduction entails long-term

initiatives in education and a rebalance of societal

resources to address core risk factors such as socio-

economic inequity. Protective factor enhancement and

promoting of competencies may be more readily

achievable with ‘relatively’ short-term comprehensive,

early, multimodal and multidisciplinary initiatives.

Though further research is needed, the findings from

this and similar reviews could enhance current services

and inform development of effective intersectoral

services for youth.

This evidence compels us to examine policy changes to

foster integration of separately financed and governed

children’s services at a local level. For many jurisdic-

tions, legislative changes could create incentives for such

services to collaborate on service delivery. Collaboration

rather than consolidation avoids creating a new bureau-

cracy, and preserves both agency autonomy and peer

checks and balances necessary for productivity. Joint

decision-making would require intersectoral governance,

pooling of some funding, and policy changes to retain

savings at the local level. Savings could finance

expansion of services for additional youth. An inter-

sectoral governance structure could include all the

sectors identified in Fig. 1, representatives of the

continuum of services and public, private, not-for-profit

funding sources.
