| Abstract|| |
Addiction and related disorders are chronic lapsing and relapsing disorders where the combination of long term pharmacological and psychosocial managements are the mainstay approaches of management. Among the psychosocial interventions, the Relapse Prevention (RP), cognitive-behavioural approach, is a strategy for reducing the likelihood and severity of relapse following the cessation or reduction of problematic behaviours. Here the assessment and management of both the intrapersonal and interpersonal determinants of relapse are undertaken. This article discusses the concepts of relapse prevention, relapse determinants and the specific interventional strategies.

| Introduction|| |
Addiction is conceptualised as a chronic relapsing brain disorder. Miller and Hester reviewed more than 500 alcoholism outcome studies and reported that more than 75% of subjects relapsed within 1 year of treatment. A study published by Hunt and colleagues demonstrated that nicotine, heroin, and alcohol produced highly similar rates of relapse over a one-year period, in the range of 80-95%. A significant proportion (40–80%) of patients receiving treatment for alcohol use disorders have at least one drink, a “lapse,” within the first year of after treatment, whereas around 20% of patients return to pre-treatment levels of alcohol use. Relapse prevention (RP) is a strategy for reducing the likelihood and severity of relapse following the cessation or reduction of problematic behaviours.
The initial transgression of problem behaviour after a quit attempt is defined as a “lapse,” which could eventually lead to continued transgressions to a level that is similar to before quitting and is defined as a “relapse”. Another possible outcome of a lapse is that the client may manage to abstain and thus continue to go forward in the path of positive change, “prolapse”. Many researchers define relapse as a process rather than as a discrete event and thus attempt to characterize the factors contributing to relapse.
Relapse prevention (RP) is a cognitive– behavioural approach with the goal of identifying and addressing high-risk situations for relapse and assisting individuals in maintaining desired behavioural changes. RP has two specific aims:
- Preventing an initial lapse and maintaining abstinence or harm reduction treatment goals
- Providing lapse management if a lapse occurs such that further relapses can be prevented.
Relapse prevention initially evolved as a calculated response to the longer-term treatment failures of other therapies. The assumption of RP is that it is problematic to expect that the effects of a treatment that is designed to moderate or eliminate an undesirable behaviour will endure beyond the termination of that treatment. Further, there are reasons to presume a problem will re-emerge on returning to the old environment that elicited and maintained the problem behaviour; for instance, forgetting the skills, techniques, and information taught during therapy; and decreased motivation.
Cognitive Behavioural model of relapse
A high-risk situation is defined as a circumstance in which an individual's attempt to refrain from a particular behaviour is threatened. They often arise without warning. While analysing high-risk situations the client is asked to generate a list of situations that are low-risk, and to determine what aspects of those situations differentiate them from the high-risk situations. High-risk situations are determined by an analysis of previous lapses and by reports of situations in which the client feels or felt “tempted.” Appropriate responses are those behaviours that lead to avoidance of high-risk situations, or behaviours that foster adaptive responses. Seemingly irrelevant decisions (SIDs) are those behaviours that are early in the path of decisions that place the client in a high-risk situation. For example, if the client understands that using alcohol in the day time triggers a binge, agreeing for a meeting in the afternoon in a restaurant that serves alcohol would be a SID.
A number of less obvious factors also influence the relapse process. These covert antecedents include lifestyle factors, such as overall stress level, one's temperament and personality, as well as cognitive factors. These may serve to set up a relapse, for example, using rationalization, denial, or a desire for immediate gratification. Lifestyle factors have been proposed as the covert antecedents most strongly related to the risk of relapse. It involves the degree of balance in the person's life between perceived external demands and internally fulfilling or enjoyable activities. Urges and cravings precipitated by psychological or environmental stimuli are also important.
An important part of RP is the notion of Abstinence violation effect (AVE), which refers to an individual's response to a relapse where often the client blames himself/herself, with a subsequent loss of perceived control. It occurs when the client perceives no intermediary step between a lapse and relapse i.e. since they have violated the rule of abstinence, “they may get most out” of the lapse. During RP, these factors need to be worked on. People who attribute the lapse to their own personal failure are likely to experience guilt and negative emotions that can, in turn, lead to increased drinking as a further attempt to avoid or escape the feelings of guilt or failure.
Another factor that may occur is the Problem of Immediate Gratification where the client settles for shorter positive outcomes and does not consider larger long term adverse consequences when they lapse. This can be worked on by creating a decisional matrix where the pros and cons of continuing the behaviour versus abstaining are written down within both shorter and longer time frames and the therapist helps the client to identify unrealistic outcome expectancies.
Marlatt, based on clinical data, describes categories of relapse determinants which help in developing a detailed taxonomy of high-risk situations. These components include both interpersonal influences by other individuals or social networks, and intrapersonal factors in which the person's response is physical or psychological.
| Relapse Determinants|| |
These can be classified as intrapersonal or interpersonal. Intrapersonal Determinants
Self-efficacy is defined as the degree to which an individual feels confident and capable of performing certain behaviour in a specific situational context. The RP model proposes that at the cessation of a habit, a client feels self-efficacious with regard to the unwanted behaviour and that this perception of self-efficacy stems from learned and practiced skills. In a prospective study among both men and women being treated for alcohol dependence using the Situational Confidence Questionnaire, higher self-efficacy scores were correlated to a longer interval for relapse to alcohol use. The relationship between self-efficacy and relapse is possibly bidirectional, meaning that individuals who are more successful report greater self-efficacy and individuals who have lapsed report lower self-efficacy. Chronic stressors may also overlap between self-efficacy and other areas of intrapersonal determinants, like emotional states, by presenting more adaptational strain on the treatment-seeking client.
Outcome expectancies can be defined as an individual's anticipation or belief of the effects of a behaviour on future experience. The expected drug effects do not necessarily correspond with the actual effects experienced after consumption. Based on operant conditioning, the motivation to use in a particular situation is based on the expected positive or negative reinforcement value of a specific outcome in that situation. Both negative and positive expectancies are related to relapse, with negative expectancies being protective against relapse and positive expectancies being a risk factor for relapse. Those who drink the most tend to have higher expectations regarding the positive effects of alcohol. In high-risk situations, the person expects alcohol to help him or her cope with negative emotions or conflict (i.e. when drinking serves as “self-medication”). Expectancies are the result of both direct and indirect (e.g. perception of the drug from peers and media) experiences.
According to this affective model of drug motivation, excessive substance use is motivated by affective regulation, both positive and negative. Later researchers such as Baker proposed the negative reinforcement model of drug addiction and posit that the escape and avoidance of negative affect is the major motive for addictive drug use. Studies with alcohol-dependent patients have shown that on-going depression increases the risk of relapse during and after treatment, and sudden increases in negative affect have been shown to immediately precede nicotine relapse. In one study, alcoholic beverage presentation and negative affect imagery led to increased subjective reporting of desire to drink and predicted time to relapse after inpatient discharge. Negative mood states associated with relapse include anger, loneliness, boredom, fatigue.
One of the most critical predictors of relapse is the individual's ability to utilize effective coping strategies in dealing with high-risk situations. Coping is defined as the thoughts and behaviours used to manage the internal and external demands of situations that are appraised as stressful. A person who can execute effective coping strategies (e.g. a behavioural strategy, such as leaving the situation, or a cognitive strategy, such as positive self-talk) is less likely to relapse compared with a person lacking those skills. Moreover, people who have coped successfully with high-risk situations are assumed to experience a heightened sense of self-efficacy.
There are various classifications of coping described. Shiffman and colleagues describe stress coping where substance use is viewed as a coping response to life stress that can function to reduce negative affect or increase positive affect. They assume a distinction between stress coping skills, which are responses intended to deal with general life stress, and temptation coping skills, which are coping responses specific to situations in which there are temptations for substance which could contribute to relapse.
Approach coping may involve attempts to accept, confront, or reframe as a means of coping, whereas avoidance coping may include distraction from cues or engaging in other activities. Approach oriented participants may see themselves as more responsible for their actions, including lapse, while avoidance-based coping may focus more on their environment than on their own actions.
Coping may also be experienced as inaction. Inaction has typically been interpreted as the acceptance of substance cues which can be described as “letting go” and not acting on an urge. “Staying in the moment” and being mindful of urges are helpful coping strategies.
Craving has been described as a cognitive experience focused on the desire to use a substance and is often related to the expectancies for the desired effect of the drug, whereas urge has been defined as the behavioural intention to use a substance. Craving can be aroused either by interoceptive or exteroceptive cues, environmental situations associated with prior heavy drinking, or with the psychological and physical effects of prior withdrawal experiences. While craving may initiate drinking, relapse is facilitated through the complementary phenomenon of loss of control, a behavioural state characterized by the relative inability to respond to either internal or external cues which regulate alcohol consumption.
Critical for craving and relapse is the process of associative learning, whereby environmental stimuli repeatedly paired with drug consumption acquire incentive-motivational value, evoking expectation of drug availability and memories of past drug euphoria.
Substance users seem to use drugs or relapse more readily in environments associated with prior drug use. The cue-reactivity paradigm, which monitors their reactions to various drug-related stimuli, has been used to explore this relationship. Drug-related stimuli elicit craving, but cue reactivity is not a consistent predictor of relapse.
Oxford English Dictionary defines motivation as “the conscious or unconscious stimulus for action towards a desired goal provided by psychological or social factors; that which gives purpose or direction to behaviour. Motivation may relate to the relapse process in two distinct ways, the motivation for positive behaviour change and the motivation to engage in the problematic behaviour. This illustrates the issue of ambivalence experienced by many patients attempting to change an addictive behaviour. Motivational Interviewing provides a means of facilitating the change process.
Positive social support is highly predictive of long-term abstinence rates across several addictive behaviours. Among social variables, the degree of social support available from the most supportive person in the network may be the best predictor of reducing drinking, and the number of supportive relationships also strongly predicts abstinence. Further, the more non-drinking friends a person with an AUD has, the better outcomes tend to be. Negative social support in the form of interpersonal conflict and social pressure to use substances has been related to an increased risk for relapse. Social pressure may be experienced directly, such as peers trying to convince a person to use, or indirectly through modelling (e.g. a friend ordering a drink at dinner) and/or cue exposure.
While many families can find addiction difficult to deal with, negative family behaviours such as withdrawing from a family member with a substance use disorder or avoiding dealing with the substance use is actually associated with more drinking. In addition to familial, marital, friend, and co-worker relations, research also suggests that community-based support services, such as recovery communities, enhance outcomes for those struggling with cessation once treatment has been completed.
Interpersonal relationships and support systems are highly influenced by intrapersonal processes such as emotion, coping, and expectancies.
Earlier models posited that various factors related to relapse progressed in a linear step wise manner. A revised model proposes that determinants described above are multidimensional and dynamic. Seemingly insignificant changes in one risk factor may kindle a downward spiral resulting in relapse. Multiple factors act at the same time act in varying degrees to ultimately lead onto relapse
Relapse factors can be viewed as distal risk factors (vulnerability in the form of temperament, personality, family loading, environment including social and economic background) and proximal factors being the various determinants of relapse acting and these factors interacting among themselves in a complex manner to lead onto relapse. Hence, the dynamic model posits a non-linear progression to relapse.
Specific Intervention strategies in Relapse Prevention
Identifying and coping with high-risk situations
Along with the client, the therapist needs to explore past circumstances and triggers of relapse. The cues may be both internal and external. Also, the client is asked to keep a current record where s/he can self-monitor thoughts, emotions or behaviours prior to a binge. Once this is done, two strategies may be employed. One is to help clients identify warning signs such as on-going stress, seemingly irrelevant decisions and significant positive outcome expectancies with the substance so that they can avoid the high-risk situation. The second is assessing coping skills of the client and imparting general skills such as relaxation, meditation or positive self-talk or dealing with the situation using drink refusal skills in social contexts when under peer pressure through assertive communication.
In RP client and therapist are equal partners and the client is encouraged to actively contribute solutions for the problem. Client is taught that overcoming the problem behaviour is not about will power rather it has to do with skills acquisition. Another technique is that the road to abstinence is broken down to smaller achievable targets so that client can easily master the task enhancing self-efficacy. Also, therapists can provide positive feedback of achievements that the client has been able to make in other facets of life.
Eliminating myths and placebo
The myths related to substance use can be elicited by exploring the outcome expectancies as well as the cultural background of the client. Following this a decisional matrix can be drawn where pros and cons of continuing or abstaining from substance are elicited and clients' beliefs may be questioned.
Lapse management includes drawing a contract with the client to limit use, to contact the therapist as soon as possible, and to evaluate the situation for factors that triggered the lapse.
Cognitive restructuring can be used to tackle cognitive errors such as the abstinence violation effect. Clients are taught to reframe their perception of lapses, to view them not as failures but as key learning opportunities resulting from an interaction between various relapse determinants, both of which can be modified in the future.
Some of the other common cognitive errors noted are statements like relapse can't happen to me”; “I'll never use alcohol or drugs again”; “I can control my use of alcohol or other drugs”; “a few drinks, pills, won't hurt”; “recovery isn't happening fast enough”; “I need alcohol or other drugs to have fun”; and “my problem is cured.” These cognitions are listed, their validity questioned, and clients have to frame alternate thoughts to replace them as in CBT.
Balanced lifestyle and Positive addiction
Global self-management strategy involves encouraging clients to pursue again those previously satisfying, nondrinking recreational activities. In addition, relaxation training, time management, and having a daily schedule can be used to help clients achieve greater lifestyle balance.
Helping clients develop positive addictions or substitute indulgences (e.g. jogging, meditation, relaxation, exercise, hobbies, or creative tasks) also help to balance their lifestyle.
Stimulus control techniques
These techniques encourage the client to remove all items directly associated with substance use from his or her home, office. To remove all paraphernalia associated with drug use such as needles, mirror, pipes, glasses, bottles. More subtle items may include the favourite chair or the music the client listened to while using alcohol. In these cases, a temporary change in seating or listening habits may be helpful. Similarly, certain social events may have become associated with excessive drinking; client may need to decline these invitations.
Urge management techniques
Urge surfing was developed by Marlatt. Using a wave metaphor, urge surfing is an imagery technique to help clients gain control over impulses to use drugs or alcohol. In this technique, the client is first taught to label internal sensations and cognitive preoccupations as an urge, and to foster an attitude of detachment from that urge. The focus is on identifying and accepting the urge, not acting on the urge or attempting to fight it.
One of the most notable developments in the last decade has been the emergence and increasing application of Mindfulness-Based Relapse Prevention (MBRP) for addictive behaviours. MBRP stresses non-judgmental attention to thoughts or urges.
Relapse road maps
Cognitive-behavioural analyses of high-risk situations that emphasize the different choices available to clients for avoiding or coping with these situations as well as their consequences. Such a “mapping out” of the likely outcomes associated with different choices along the way can be helpful in identifying SIDs.
Outcome Studies for Relapse Prevention
In a meta-analysis by Carroll, more than 24 RCT's have been evaluated for the effectiveness of RP on substance use outcomes. Review of this body of literature suggests that, across substances of abuse but most strongly for smoking cessation, there is evidence for the effectiveness of relapse prevention compared with no treatment controls. However, evidence regarding its superiority relative to other active treatments has been less consistent. Outcomes in which relapse prevention may hold particular promise include reducing severity of relapses, enhanced durability of effects, and particularly for patients at higher levels of impairment along dimensions such as psychopathology or dependence severity.
In a subsequent meta-analysis by Irwin, twenty-six published and unpublished studies representing a sample of 9,504 participants were included. Results indicated that RP was generally effective, particularly for alcohol problems. Additionally, outcome was moderated by several variables. Specifically, RP was most effective when applied to alcohol or polysubstance use disorders, combined with the adjunctive use of medication, and when evaluated immediately following treatment. Moderation analyses suggested that RP was consistently efficacious across treatment modalities (individual vs. group) and settings (inpatient vs. outpatient) 22.
In a study by McCrady evaluating the effectiveness of psychological interventions for alcohol use disorder such as Brief Interventions and Relapse Prevention was classified as efficacious.
In a 2013 Cochrane review which also discussed regarding relapse prevention in smokers the authors concluded that there is insufficient evidence to support the use of any specific behavioural intervention to help smokers who have successfully quit for a short time to avoid relapse. The verdict is strongest for interventions focused on identifying and resolving tempting situations, as most studies were concerned with these.
Following the initial introduction of the RP model in the 1980s, its widespread application largely outpaced efforts to systematically validate the model and test its underlying assumptions. The Relapse Replication and Extension Project (RREP) was a multisite study to replicate and extend Marlatt's taxonomy of relapse precipitants. In addition to replicating Marlatt's original taxonomic system, three independent research teams utilized prospective designs to identify additional predictors of relapse and developed and evaluated two alternative systems for assessing high-risk relapse situations. These conclusions are: (1) reliability of Marlatt's taxonomic system was variable both within and across the three research sites; (2) Marlatt's taxonomic system showed little predictive validity in analyses that used pre-treatment relapse data to predict post-treatment relapse, (3) an alternative taxonomy provided little more predictive validity than the original taxonomy even though it measured more dimensions of relapse.
The dynamic model of relapse takes many of the RREP criticisms into account. Ecological momentary assessment, either via electronic device or interactive voice response methodology, could provide the data necessary to fully test the dynamic model of relapse.
Relapse Prevention in other areas
Principles of relapse prevention have been used in the treatment of sex offenders. In a 2003 meta-analysis relapse prevention treatment revealed moderate mean reductions in recidivism and certain elements of the relapse prevention model (i.e. training significant others in the programme model and identifying the offense chain) yielded stronger effects than others (i.e. provision of booster/aftercare sessions and developing coping skills).
RP has also been used in eating disorders in combination with other interventions such as CBT and problem-solving skills.
Future research with a data set that includes multiple measures of risk factors over multiple days can help in validating the dynamic model of relapse. Elucidating the “active ingredients” of CBT treatments remains an important and challenging goal, Also, integration of neurocognitive parameters in relapse models as well as neural (such as functional circuitry involved in relapse) and genetic markers of relapse will be major challenges moving ahead.
