Harith Swadi is Associate Professor in the Department of Psychiatry and Behavioural Sciences at the United Arab Emirates University (PO Box 17666, Al Ain, United Arab Emirates; Fax: (9713) 672 995; e-mail: samitara{at}emirates.net.ae) and a consultant child and adolescent psychiatrist currently practising in the Middle East. Formerly, he was Senior Lecturer at the St Thomas' Hospital Campus of the United Medical and Dental Schools.
There is increasing evidence that substance misuse among British adolescents is escalating (Miller & Plant, 1996; Sutherland & Willner, 1998). Swadi (1992) found that, among adolescents aged 1217 years referred to mental health services, the prevalence of drug use was 13.1% (16.3% among boys and 9.3% among girls). Despite this relatively high prevalence, there are very few organised treatment services for adolescents in the UK. Instead, there is extensive emphasis on prevention even though there is no universal agreement on what prevention can achieve. This approach also overlooks the fact that a significant number of adolescents fail to respond to preventive measures in any form.

Substance misuse in adolescents is, on the whole, significantly dissimilar to that in adults. The aetiological factors, the patterns of use, the context of use and the therapeutic approaches can be different:
In conclusion, the needs of adolescent substance users are different from those of adults. Furthermore, they present to services with a complex pattern of psychological, personal and social problems and needs, including delinquent behaviour, homelessness, family problems and educational and vocational needs.

It is also important to determine whether the adolescent is in need of protection and/or crisis intervention, and whether there are any urgent legal issues that need to be addressed (Meyers et al, 1999).

The assessment should also determine the most suitable treatment setting for the adolescent. The possibilities include out-patient, residential and day programmes. Most cases that are not severe and chaotic can be dealt with on an out-patient or day basis, with particular attention to educational needs. However, most will need input from different professionals with different skills and the support and collaboration of a number of agencies such as social services, voluntary organisations, education and health.
The main components of a comprehensive assessment are described below.
Pattern of use and its significance
Unlike adult addicts who mainly use psychoactive substances just to feel normal, adolescents use psychoactive substances for many different reasons. It is essential to determine the context of use, as it has a crucial bearing on the intervention process. There are five different clinical contexts of adolescent involvement (Nowinski, 1990):
Exploratory or experimental
The primary motive in this type of substance misuse is curiosity and risk-taking. The mood-altering effects are secondary to the adventure of use. Use takes place mostly with others. The user may try more than one substance, but usually not more than a few times. The adolescent is experimenting with the mood swing caused by psychoactive substances.
Social
The context here is strictly social, for example, parties, friends' houses, car parks, bicycle sheds, etc. The primary motive is social acceptance. The peer group plays a large role. Substances are shared freely or sold at cost. The aim is to fit in with the crowd and to loosen up. The adolescent is usually still experimenting with the mood swing.
Emotional or instrumental
In this context, the adolescent learns to use substances purposefully to manipulate feelings, emotions and behaviour, that is, to elicit or to inhibit certain behaviours and feelings. The adolescent is generally seeking the mood swing. There are two types of instrumental use:
Generative\hedonistic
The purpose is to seek pleasure and to have fun. Use is characterised by binges motivated by the desire to get high and feel good. The purpose is to elicit pleasurable feelings or to explore new feelings or emotions.
Suppressive\compensatory
The purpose is to cope with stress and uncomfortable feelings, that is, to suppress negative and distressing emotions. Mostly, use is solitary but also takes place with the peer group.
Habitual
Typically, the frequency of use begins to show a characteristic of compulsiveness and preoccupation. Lifestyle and activities begin to converge around psychoactive substances. Former relationships, activities and friends begin to be replaced by new substance-related ones. Sleep and concentration difficulties begin to appear. Withdrawal symptoms appear occasionally, especially after periods of heavy sustained use. Craving may occur, tolerance may increase and the adolescent may begin to think about use most of the time. Behavioural problems increase and school performance becomes seriously affected. The adolescent is preoccupied with the mood swing.
Dependent or addictive
This is the stage at which physical and psychological addictions become the main feature. Tolerance, craving, withdrawal symptoms and the compulsion to use become prominent. The adolescent is completely preoccupied with use and life centres around the substance and the next fix. The adolescent takes substances only to feel normal.
Adolescents in the first two categories of use (exploratory and social) tend to be primarily involved with lower-tariff substances such as volatile substances, cannabis and amphetamines, whereas those using habitually could be involved in a variety of substances, including opiates and crack cocaine.
Substance misuse has different consequences depending on the individual, the patterns of use and the environment. These consequences must be documented. Problematic substance use can be defined as that which has resulted in demonstrable or documented evidence of sustained adverse consequences, with evidence of continued use despite these consequences. This would be in areas related to education (e.g. being expelled or having left school prematurely), delinquency (e.g. being arrested or getting involved in theft), intra-familial relationships (e.g. running away from home or violence towards family members) and psychiatric symptomatology (e.g. severe conduct problems or depressive symptoms). Such consequences make treatment and/or intervention extremely desirable if not necessary.
Associated psychopathology (comorbidity)
Psychopathogy is increasingly emerging as a very influential factor, in relation not only to initiation into substance use but also to response to intervention and outcome (Scourfield et al, 1996). Clinicians should be able to recognise and treat coexisting psychopathology. Conduct problems have long been recognised as associates of substance misuse. The strong links with emotional problems are now universally accepted. Consistently, reports indicate that affective symptoms predominate in females whereas conduct problems are more common in males. In an earlier paper (Swadi, 1992), I stressed the need to be aware of the existence of mood disorders among substance users, as they are easy to miss, particularly when associated with conduct and antisocial behaviour. Substance misuse is also related to increased suicidal ideation and attempted suicide. Many adolescents who overdose do so while under the influence of alcohol or other drugs. A major risk factor for completed suicide after parasuicide in adolescents is substance misuse (Hawton et al, 1993).
Young substance misusers also show higher rates of psychosomatic complaints, anxiety, relationship problems and social dysfunction. Adolescents with poor coping skills tend to use psychoactive substances to deal with stress (Labouvie, 1986) and as a means of emotional self-regulation. There is also an emerging link between eating disorders (both anorexia and bulimia) and substance misuse, particularly alcohol use (Lavik et al, 1991). American literature consistently reports strong links between attention-deficit hyperactivity disorder and substance misuse in adolescents (e.g. Milberger et al, 1997). A psychiatric assessment must include a good account of adverse life events, particularly victimisation and loss.
Another important point in the assessment is the need to ascertain the temporal relationship between existing psychopathology and substance misuse. Particular care should be taken when assessing adolescents with coexisting affective problems and substance misuse. Psychiatric problems may be the result of substance misuse, particularly in the case of central nervous system depressants. On the other hand, many adolescents with psychopathology may turn to psychoactive substances for psychological relief.
Functioning
The assessment of functioning should include an appraisal of the adolescent's motivation for treatment and his or her education, coping skills, social skills, self-perception and emotional adjustment. The primary objective is to determine the adolescent's strengths/assets and weaknesses/deficiencies. Building on assets and addressing deficiencies is an essential part of the intervention process.
Family assessment
This is almost a must given the many different ways in which family factors play a role in adolescent substance misuse. Family background and parenting styles, including parental divorce, parental discord, family disruption, negative communication, inconsistent parental discipline, and lack of closeness, have been identified as influential risk factors in adolescent drug use (Stoker & Swadi 1990; Isohanni et al, 1991). Families of children who misuse drugs were characterised as being those whose fathers were distant and disengaged and whose mothers were too involved (Kaufman & Kaufman, 1979; Stoker & Swadi, 1990). Families can also behave in a way that increases the risk of maintaining substance use. Commonly, clinicians refer to enabling behaviour (Nowinski, 1990). This is a natural response by the family to stay intact and to survive. It motivates families to compensate for one dysfunctional member and to avoid issues that threaten its integrity. It may involve all family members siblings may conspire to keep parents in the dark or parents may avoid the subject. Bailing out, minimising and avoiding are the most frequent enabling behaviours. The family assessment should focus on family dynamics, communication patterns, cohesion, affect and value transmission.

Detoxification
Alcohol
By the time they are referred, adolescents are unlikely to have developed an alcohol dependence syndrome that requires detoxification. However, if the assessment confirms the presence of dependence, then detoxification along the conventional lines used in adults is indicated. Benzodiazepines are useful in this respect as they have been shown to reduce withdrawal severity and the likelihood of delirium (for a detailed account see Lejoyeux et al, 1998). The dosage and the type of benzodiazepine and the duration of the detoxification regimen depend on the severity of the withdrawal syndrome and the motivation of the adolescent. However, guidance can also be gained from the use of withdrawal scales. Other drugs that may be helpful in reducing the severity of withdrawal syndrome include phenothiazines, clonidine, acamprosate, naltrexone, carbamazepine and beta-blockers, but they are not as effective as benzodiazepines in dealing with the risk of delirium and convulsions.
Opiates
Regarding opiates, detoxification usually follows the same lines as with adults. It may be carried out on an out-patient or residential basis depending on the severity and the presence of a supportive environment in the community. Methadone is the drug of choice. Studies in adult populations suggest that other drugs such as clonidine and naltrexone may also be useful. Symptomatic relief from signs of the withdrawal syndrome (such as diarrhoea and central nervous system arousal) may also be useful. The dose and duration of treatment with methadone depend, as in alcohol dependence, on the severity of dependence and the adolescent's motivation. However, the aim should be rapid reduction long-term methadone maintenance is not advisable in young people.
Other substances
Detoxification programmes for dependence on other drugs such as benzodiazepines and cocaine also follow the same lines as with adults. No pharmacological substitutes are available for them and the objective should be graded reduction of use. However, the use of antidepressants such as desipramine and fluoxetine may help, particularly in adolescents with coexisting affective disorders (Kaminer, 1992; Riggs et al, 1997).
Individual counselling
A recent development in individual counselling is the use of brief intervention techniques. This began with the use of simple advice in primary care settings leading to significant reduction in use, particularly in relation to alcohol use. However, a major new approach is that based on the theory of change (Prochaska & DiClemente, 1982); motivational enhancement interviewing (Miller & Rollnick, 1991). This approach is becoming increasingly popular and has added a new and exciting dimension to therapeutic intervention.
The cycle of change identifies 56 stages intervention begins with identifying where in this cycle the person is. The objective is to help the young person move along from one stage to another through increasing motivation to change behavioural patterns, including substance use. This approach is particularly useful with resistant clients (such as adolescents). Different stages require different techniques. The stages and main objectives of the therapist at each stage are:
Stage I
Pre-contemplation
User is not thinking about stopping drinking raise doubt; increase perception of risks and problems with substance use.
Stage II
Contemplation
User is thinking about change: "Maybe I should stop drinking" tip the balance; evoke reasons for change; strengthen self-efficacy for change.
Stage III
Determination
User is determined to change: "I must stop drinking" help to determine the best course of action for change.
Stage IV
Action
User actually changes: "I stopped drinking" help client to take steps towards maintaining change.
Stage V
Maintenance
User continues not to drink help client to identify and use strategies to prevent relapse.
Stage IV
Relapse
User goes back to drinking help to renew contemplation.
In essence, people who misuse substances who are not sufficiently motivated to change, or who do not appear ready to use treatment to deal with their drug problem, are at higher risk for early relapse (DeLeon et al, 1997).
Family work and therapy
Families can be helpful in the process of therapy. They can also be obstacles. Families and family dynamics have been shown to be influential as risk factors for initiation and progression (the process of moving from experimentation to chronic use). On the other hand, most recovered addicts report family systems as being very helpful in their recovery. In particular, the family can help improve compliance with treatment that involves medication.
Family therapy can take the form of structural, strategic or behavioural work. It should be time-limited and goal-oriented, especially using goals identified by the family. Family tasks are very useful in this sense. The therapist should keep the issue of drug use alive and avoid getting into other red herring issues. If the family members wish to discuss other issues, they should be advised that they might wish to discuss these after the current goal is achieved. Parents' roles should be enhanced and given a major advisory and decision-making capacity vis-à-vis the treatment process. Family therapy should also help to reduce conflict among family members and help the adolescent replace friendships that encourage deviant behaviour with others that encourage social conformity (Knight & Simpson, 1996).
A recent approach in family therapy is multi-dimensional family therapy (MDFT). This is an out-patient, family-based, behaviourallystrategically oriented approach (Liddle, 1998). It views adolescent drug use in terms of a matrix of influences (i.e. individual, family, peer and community). Behavioural changes occur via multiple pathways, in differing contexts and through different mechanisms.
The MDFT model includes individual and family sessions (which may include others outside the family). The therapist helps to organise treatment by introducing several generic themes. These are different for the parents (e.g. feeling abused and without ways to influence their child) and adolescents (e.g. feeling disconnected and angry with their parents). The therapist uses these themes of parentchild conflict as assessment tools and as a way to identify workable content in the sessions.
During individual sessions, the teenager is helped to acquire communication skills and problem-solving skills to deal better with life stressors. Job skills and vocational training are also part of treatment. At the same time, sessions with the parents address parenting styles and belief systems. The parents are helped to examine their particular parenting style, to distinguish influence from control, and to develop parenting approaches that lead to positive influence on their child (Liddle et al, 1998).
Group work (therapy)
This can be substance misuse-oriented or non-substance misuse-oriented. The latter can deal with social skills, relationships and can have an element of education and catharsis. Group therapy, particularly that which involves peer confrontation, seems to be effective for adolescents, at least in the short term (Wheeler & Malmquist, 1987). However, most substance misuse-oriented work has really been based on the Alcoholics Anonymous (12-step) model (Alford et al, 1991). The basic objective is self-help and relapse prevention. However, although this model of work can be beneficial for adults, there are some problems with adolescents. The concept of self-help has to be modified to take into account the process of adolescent development.
External support network, education and employment
For adolescents in treatment, abstinence is a major change in lifestyle, and needs support to be maintained. Once treatment is completed, it is important for the adolescent, in order to function satisfactorily and stay off drugs, to be able to return to an environment that will support this. The nature and degree of support must be explored as part of the continued review and assessment process. Such support will inevitably involve opportunities for adequate accommodation, education, training and employment. Often, it is also useful to provide psychological support either on a regular or an ad hoc basis. Most well-developed treatment programmes have included an element of extended day or community follow-up and support.

Pharmacological methods of relapse prevention have been used mostly with alcohol dependence and aim at dealing with and reducing craving, which is the main cause of short-term relapse. Apart from the use of disulfiram (which has not been evaluated in adolescents), adult studies seem to indicate that some relatively new drugs such as naltrexone and acamprosate show some promise in reducing craving for alcohol, particularly in those with comorbid disorders (Bonn, 1999). However, there are no similar studies among adolescent populations.
Cognitivebehavioural therapy is increasingly gaining credence in relapse prevention. This approach aims to help generate mechanisms to cope with situations of high risk for relapse. Social pressure is the most important high-risk situation for adolescents. The indications are that abstinence is directly related to the ability of the adolescent to develop coping strategies to deal with social pressure. The most successful strategies are those characterised by a cognitivebehavioural approach, such as avoiding high-risk situations, refusal and engaging in alternative activity (Myers & Brown 1990).
| Box 1. Points of good practice Some parents panic when they learn that their child is abusing drugs it is wise not to join them. In many cases, all that is needed is simple counselling Families must be involved in every case. They have a great deal to offer, but their involvement does not necessarily have to follow the conventional lines of family therapy Substance misuse may be a symptom of a dysfunctional family system, no more that system must be helped to become more functional Always look for psychopathology and deal with it vigorously. It may not come in the form of a full-blown syndrome, but it may, nevertheless, be very significant to the adolescent Substance misuse is not necessarily a conduct disorder. It is likely that it is a manifestation of an emotional problem Sometimes it is wiser to view substance misuse as a behaviour that needs to be changed, rather than a disorder that has to be treated The motivation to change always comes from within. The strategy is to facilitate that process. Human beings do not change a behaviour unless they have to, or wish to A good assessment is a sound investment Try to avoid treating adolescents within adult services. Some bad habits of adult misusers (like injecting) tend to rub off Multi-agency intervention is the rule rather than the exception
