Objective: To identify the determinants of service use by young Canadians with mental health problems.
Methods: Data were drawn from a recent large Canadian mental health survey. The analyses were conducted on a subsample of 1092 Canadians aged 15 to 24 years and identified as presenting a mood disorder, an anxiety disorder, or a substance-related disorder in the 12 months preceding the survey. We classified variables potentially associated with any type of service use for a mental health problem over a 12-month period according to predisposing, enabling, and need factors. We conducted weighted multivariate logistic regressions to determine the association of each factor with service use.
Results: In the final model, being female and living alone were the predisposing factors associated with service use. None of the enabling factors predicted help seeking. In regard to the perceived need factors, those who had difficulties with social situations were more likely to use services. Having a mood disorder and (or) having a diagnosed chronic illness were the evaluated need factors associated with service use.
Conclusion: Certain groups of young Canadians are less likely to seek help for mental health problems and could be the target of interventions aimed at increasing service use.

Clinical Implications
* Only 25% of young Canadians with mental health problems seek help. Therefore, it is essential to initiate interventions that will aim at increasing their use of services.
* Sex, living arrangement, reaction to social situations, diagnosis of mood disorders, and chronic physical disorder influence the likelihood of service use.
* Interventions to encourage service use should be targeted toward people who are less likely to use the services, namely, young men, young people living with their parents or with unrelated others, and people diagnosed with an anxiety or a substance-related disorder.
Limitations
* The survey, which is not specifically designed for young people, does not contain information on familial context.
* The study does not account for the impact of income on service use.
* No distinction is made between types of service, disorder, age, and sex.

National surveys across developed countries indicate that, when compared with older age groups, people aged 15 to 24 years have the highest rates of mental disorders (1,2). This trend is also observed in the CCHS 1.2 (3), which specifies that 18% of Canadians aged 15 to 24 years meet the criteria for a mood disorder, an anxiety disorder, or a substance-related disorder, compared with almost 12% of those aged 25 to 44 years, 8% of those aged 45 to 64 years, and 3% of those aged 65 years and over. Although young people are particularly at risk for mental disorders, they underuse services for these problems (1,3). Therefore, it is important to investigate factors associated with service use in this particular subgroup.
Prior research has examined potential determinants of help seeking by young people with mental disorders. However, these studies have overlooked some of the factors examined in studies targeting adults in general. For example, factors associated with service use, such as the size of the social network (4) and certain types of living arrangements (5), may also influence young people's help-seeking behaviour. Moreover, few studies based their analyses on an established model of service use. Finally, the only Canadian study that explored the determinants of help seeking by young people with mental disorders only considered a few variables (6). Considering these limitations, this study aims to identify the factors associated with service use for mental health problems by young Canadians. We used Andersen's Behavioural Model of Health Care Use as a theoretical framework (7,8).
Method
Data were drawn from the CCHS 1.2 (n = 36 984), which is a nationally representative, computer-assisted, face-to-face household survey. The sampling procedure used was a multistage stratified cluster design. The response rate was 77% (3). A more detailed description of the methodology used for this survey is provided elsewhere in this issue (9).
Sample
For the present study, the sample (n = 1092) included people aged 15 to 24 years meeting the criteria for mood disorders (major depressive episode or mania), anxiety disorders (panic disorders, social phobia, or agoraphobia), or substancerelated disorders (alcohol or illicit drug dependence) during the 12 months preceding the survey. We assessed mental disorders, using a modified version of the WMH-CIDI according to the DSM-IV (3).
Variables
This study looked at the determinants of service use for mental health problems over a 12-month period. The services considered included hospitalization, as well as consultation with psychiatrists, psychologists, GPs, nurses, social workers, support groups, help lines, alternative health care providers, and clergy.
We looked at the determinants that were found to be associated with service use in previous studies and classified them according to Andersen's Behavioural Model of Health Care Use (7,8), an established framework used to study service use for mental health problems (4,10,11 ). The model suggests that use of health services is a function of predisposing, enabling, and need factors. Predisposing factors are present before illness onset. They are related to the individual's propensity to service use. In the present study, the predisposing factors included age, sex, country of origin (Canada or other), type of living arrangement, and occupation (that is, school attendance and employment status). The enabling factors are related to the means by which individuals might access mental health services, for example, factors influencing knowledge about where to seek help. The enabling factors considered in this study were social support, determined by the global score on the MOS social support survey form (12); size of the social network; mental disorders among relatives; province of residence; and MIZ. MIZ typology devises areas outside CMAs and CAs according to the percentage of people commuting to and the distance from a CMA or a CA. The MIZ classification better reflects the urban-rural continuum than is possible with the urban-rural dichotomy (13).
Originally, a third category in Andersen's model comprised perceived and evaluated needs. However, in recent studies using Andersen's model, perceived and evaluated needs were considered separately (10,11). This study follows this trend. The perceived need factors included perception of mental and physical health, ability to face day-to-day demands, reaction to social situations, and psychological distress. A global measure of psychological distress was assessed by the KlO symptom scale (14). The evaluated need factors category comprised each assessed disorder (that is, mood disorders, anxiety disorders, or substance-related disorders) and their cooccurrence, as well as each chronic physical disorder.
Analyses
We conducted frequency analyses to assess the 12-month prevalence of any service use. We used multivariate logistic regressions to determine the association of each of the predisposing, enabling, perceived, and evaluated need factors with service use. According to Andersen's model, variables were entered in blocks: predisposing, enabling, perceived need, and evaluated need. To account for the complexity of the CCHS 1.2 sampling plan, we conducted analyses using the Wesvar software (15) and applied bootstrap weights. The strength of the associations is reported in ORs, with a 95%CI.
Results
Over a period of 12 months, only 25% of people with a mental disorder consulted for mental health problems. The results of the regressions showed that, when only predisposing factors were entered into the model, being female increased the likelihood of service use for mental health problems. Young people who were unemployed, whether attending school or not, were more likely to use the services than were those who were employed and (or) attending school. Moreover, people living with someone were less likely to seek help than were those living alone.
With the enabling factors added to the model, being female remained associated with service use. People living with someone were still less likely to seek help than were people living alone, whereas occupation ceased to be a significant predictor. Regarding the enabling factors, having relatives experiencing the same disorder and having more social support predicted service use.
When perceived need factors were added to the model, being female, living alone, and having relatives with the same disorder remained associated with service use. Social support ceased to be a significant predictor. In addition, those who perceived their mental health as poor or fair were 4 times more likely to use any service during the 1-year period than were those who perceived it as excellent. Having difficulties with social situations was also a predictor of help seeking.
The final model was obtained with the inclusion of evaluated need factors. Being female remained a predictor of service use. Canadians who were living with someone were less likely to use the services than were those living alone, with the exception of those who were living with a partner and (or) a child. The association between having difficulties with social situations and service use persisted, whereas the perception of mental health ceased to be a significant predictor. Having a mood disorder and having a diagnosed chronic physical disability were associated with an increased likelihood of service use.
Discussion
Results from the CCHS 1.2 indicate that few Canadians aged 15 to 24 years use services for their mental health problems. This suggests a need for interventions.
We explored various potential determinants of service use to identify those that predicted help seeking. A final regression model emerged from the simultaneous inclusion of predisposing, enabling, perceived need, and evaluated need factors. Regarding the predisposing factors, young women were more likely to use the services than were young men. The direction of this finding is supported by previous studies that have found an association between sex and service use (16-19). Our study was also interested in the association between types of living arrangement and help seeking. Living alone was also found to be a significant predictor of frequent service use in a study of adults of all ages (5). However, of the studies concerned with young people, this is the first to examine the association between this type of living arrangement and help seeking. We also found that being unemployed, whether attending school or not, increased the likelihood of service use. However, this association disappeared when enabling factors were entered into the model. Biddle and others also studied the impact of occupation on consultation of GPs for mental health problems and found no association (20).
No enabling factors had a significant impact on the final model. Social support was a predictor of service use until perceived need factors were entered into the model. In the literature, findings concerning the association between social support and service use for mental health problems are inconsistent. Biddle and others found that social support was not a predictor of consultation with a GP (20), whereas Saunders and others found that use of informal support was associated with service use (21). These inconsistencies could result from conceptual differences in the definition of social support or from the type of services studied. We also found that having relatives who suffered from the same disorder was associated with an increased likelihood of service use, but the association disappeared when evaluated need factors were added to the model. Cunningham and others (22) and Wu and others (23) have demonstrated that, when relatives received mental health care, young people were significantly more likely to use services. Unfortunately, information concerning the use of services by relatives was not available in the CCHS 1.2.
In the final model, having difficulties with social situations was associated with an increased likelihood of help seeking. In previous studies focusing on young people, this specific measure of impairment was not explored, although some studies examined the impact of other impairment variables. Even if the definition of these variables varied considerably between studies, impairment was found to be associated with service use (23-25). The perception of poor or fair mental health was also found to be a predictor of service use, but its influence disappeared in the final model, with the inclusion of evaluated need factors. Biddle and others did not include evaluated need factors in their final model (20) and found that perception of mental health was not a predictor of consultation. Bearing in mind that they only investigated help seeking from a GP, these diverging results could indicate that the impact of this variable may vary according to the type of professional considered.
Finally, evaluated need factors were entered into the model. We found that having a diagnosed chronic physical disability increased the likelihood of service use. Wu and others have comparable findings (23), whereas Haarasilta and others found no significant association (26). A possible explanation for this association is that regular contact with health care professionals for physical problems may give more opportunities to discuss mental health issues and may increase the likelihood of being identified as having a mental health problem. We also found that young people with a mood disorder were more likely to use services than were those with either an anxiety disorder or a substance-related disorder. This conclusion can be reached because our sample only includes people diagnosed with one of these 3 disorders; thus not having one disorder implies having one of the others. This result cannot be directly compared with previous findings, since the population (for example, the general population vs people with mental disorders) and the disorders studied differ between studies.
Some variables that were not associated with service use in the present study found empirical support in prior studies targeting young people. For instance, some studies identified age as a predictor of service use for mental health problems, but the direction of the association is inconsistent (16,19,23,24,27). Moreover, some studies indicated that age is not a significant predictor of service use (17,19,25,26). These inconsistencies may result from an interest in different age groups, different countries, and differences in the setting surveyed (for example, school or community). Finally, the size of the social network was only considered by studies targeting adults (4). Therefore, the absence of association for young people could be specific to this population.
This study has limitations that should be noted. Considering that the survey was not specifically designed for young people, data on specific determinants of service use by youth were not available for the analyses. For instance, there is a lack of information on other family members and on family functioning. Previous studies have found that determinants related to familial context, such as the impact of symptoms on family functioning (24) and parents' marital status (21), are associated with help seeking. Therefore, this study may overlook predictors of service use.
Further, when considering young people, it is difficult to correctly engage some concepts. One problematic variable is income. With the information collected by the CCHS 1.2, it is impossible to establish the extent of the monetary support provided by parents. Thus the declared personal income does not necessarily reflect the amount of money that a young person may benefit from. Further, many young people are unaware of their parents' income; thus missing data for family income are substantial.
Future research could examine determinants of health care use for particular types of services, disorders, and ages, and for both sexes. It has been demonstrated that specific determinants may be associated with different types of services (23,24,28). Certain determinants may be associated with service use only for specific types of disorders or may vary for adolescents and young adults as well as for men and women.
Conclusions
Despite the high prevalence of mental disorders among young Canadians, this study revealed that relatively few youth consulted a professional for their mental health problem. It is therefore essential to initiate interventions that will aim at increasing young Canadians' use of services for such problems.
This study also provides unique information about the determinants of service use by young Canadians. The results indicate that certain groups of people are less likely to use the services for mental health problems. These groups can be targeted to increase service use. Efforts should be made to reach young men, people living with their parents, and those living with unrelated others. The results indicate that people with anxiety disorders and substance-related disorders are less likely to seek help. Consequently, interventions aimed at increasing the detection of these disorders may be required. For example, interventions could aim at increasing parents' capacity to detect mental health disorders and to incite their children to seek professional support.
