He points out that SUD is not a single homogenous set ofsymptoms even though the diverse symptom expressions may reflect some commonunderlying mechanisms. Sher notes that behavior indicators, risk factors, andconsequences are not necessarily equivalent to addiction or to each other. Perhapsmost importantly, he distinguishes recovery from the return to a pre-addictionstate. Addiction continues to be one of the most serious and intractableproblems facing society with alcohol use being the third leading preventablecause https://thepaloaltodigest.com/top-5-advantages-of-staying-in-a-sober-living-house/ of death in the United States (Stahre.2014). The article by Bickel, Crabbe,and Sher (2019) features presentations of two major approaches toaddiction by prominent proponents John Crabbe and Warren Bickel with discussionby noted researcher Kenneth Sher. The article provides an opportunity to examinehow these approaches model addiction in terms of substance use disorder (SUD)criteria and to consider their potential for impact on alcohol and drug usedisorders and interventions in the nonacademic world.
- Studies show that repeated use of a substance (or an activity), encouraged by a surge in dopamine, creates changes in the wiring of the brain—and those changes are reversible after drug use stops.
- Because assessing benefits in large patient groups over time is difficult, diagnostic thresholds are always subject to debate and adjustments.
- The number of informants was not determined in advance, and we had the option of continuing the recruitment process and including informants even if some data from the main study were lacking.
- Psychological Models are a useful tool in understanding the unhealthy behaviours people are susceptible to from addiction.
- A subsequent 2000 paper by McLellan et al. [2] examined whether data justify distinguishing addiction from other conditions for which a disease label is rarely questioned, such as diabetes, hypertension or asthma.
- Dopamine is the neurotransmitter activated by rewarding activities as a way of increasing the likelihood of engaging in such activities in the future.
- In addressing the utility of rodent models of addiction, Crabbe describes thereductionist animal model approach to understanding a complex human behavior byfirst manipulating rodents to simulate distinct key behaviors of addiction and thensynthesizing the inferred fundamental principles into a heuristic model.
Lessons from genetics
That capacity is called neuroplasticity, and it is the basis of all learning and change. In addition, mounting evidence suggests that the brain changes of addiction do not reflect abnormal processes—they are the same processes involved in all learning. And the addicted brain returns to normal, gradually rewiring itself after substance use stops. Calling addiction a brain disorder means, for one thing, that the machinery of addiction is complex and subtle, because the brain is complex and often subtle.
Understanding Own Substance Use
This estimate of harmfulness represents an expectancy related to using these substances in the described patterns. A comprehensive understanding of these models will help to shed light on the multiple factors that contribute to the development and maintenance of addiction, ultimately supporting more effective and evidence-based approaches to treatment and recovery. Aside from this, animal studies possess a tendency to ineffectively translate to clinical situations. Some argue this lack of translatability is a consequence of ill-considered animal study designs, one example being the lack of alternative options to drug taking in classic self-administration studies (Ahmed, 2010). The decision to administer a substance in this case would not illustrate the decision-making process of an addicted individual, and as such is unrepresentative. Some addictive criteria, such as escalation of drug use, can be efficaciously modelled in non-human animal models, whilst other addictive complexities fail in human recapitulation (Ahmed, 2011).
- Instead, research indicates that it is more related to what else is, or isn’t, going on in a person’s life that makes the sensation a substance induces so attractive.
- As we will show, stating that brain mechanisms are critical for understanding and treating addiction in no way negates the role of psychological, social and socioeconomic processes as both causes and consequences of substance use.
- Neuroticism is linked to a wide array of mental health problems, including anxiety, depression, and eating disorders as well as substance abuse.
- Much of this research has centred around protocols allowing laboratory growth of in vitro neural cells that originate from embryonic stem cells (ESCs) or induced pluripotent stem cells (IPSCs) (Altimus et al., 2020).
- Some individuals may be more affected by the rewarding effects of drugs of abuse because they are trying their best to regulate painful emotions.
What are the Psychological Models of Addiction?
For Freud, the goal of psychoanalysis was to strengthen the ego, and to give it more control over the id and more independence from the superego. He believed that most mental disorders (e.g., anxiety) were due to the effect of unrestrained feelings. Increased awareness through psychoanalysis can help the individual to become less self-punitive and be able to tolerate their emotional experiences. Psychological growth requires self-acceptance, which is a state of mind that marks the end of the life-consuming struggle to transform oneself (and others) into the person one wishes one were (or wishes they were).
- In its simplest form, drug addiction can be seen as a way of hacking the brain—of finding a shortcut to feelings of emotional reward by bypassing the normal activities that stimulate such sensations and directly manipulating the neurochemicals responsible for them.
- Research has shown that spirituality can play a significant role in addiction recovery, with many individuals reporting that their spiritual beliefs or practices have been instrumental in their ability to overcome addiction.
- As such,incorporating CBT into behavioral economics based interventions might enhance theireffectiveness.
- We considered that to be sufficient to answer the research question about how the informants perceived and reflected on the recovery process after they were discharged from inpatient treatment; hence data saturation had been achieved [20, 24].

It would be possible to program a self-drivingcar to periodically swerve the vehicle but this would not provide much help inunderstanding erratic driving by intoxicated human drivers. Critics question the existence of compulsivity in addiction altogether [5,6,7, 89], typically using a literal interpretation, i.e., that a person who uses alcohol or drugs simply can not do otherwise. For alcohol addiction, meta-analysis of twin and adoption studies has estimated heritability at ~50%, while estimates for opioid addiction are even higher [44, 45].

Authors should include a subsection in their methods description titled “Transparency and Openness.” This subsection should detail the efforts the authors have made to comply with the Transparency and Openness Promotion (TOP) guidelines. Specifically, APA expects authors to have their data available throughout the editorial review process and for at least 5 years after the date of publication. For studies that report randomized clinical trials or meta-analyses, the abstract also must be consistent with the guidelines set forth by JARS or MARS guidelines, respectively. Thus, in preparing a manuscript, please ensure that it is consistent with the guidelines stated below.
Everything You Need to Know About Psychological Dependence
For those reasons and others, the disease model of addiction, while well-intentioned, is highly controversial. Experts point to the fact that many with substance use disorders quit for life, with or without treatment. They also observe that age 18 to 25 is the peak period of illicit drug use, indicating it is often a developmental disorder, a temporary form of disengagement from life for any number of possible reasons.
How we reviewed this article:
Resolving this issue remains challenging in addiction, but once again, this is not different from other areas of medicine [see e.g., [12] for type 2 diabetes]. Longitudinal studies that track patient trajectories over time may have a better ability to identify subpopulations Top 5 Advantages of Staying in a Sober Living House than cross-sectional assessments [13]. Furthermore, some communities are targeted more heavily with alcohol and tobacco advertisements and have more availability of drugs of abuse than others, particularly impoverished communities (Primack et al., 2007; Rose et al., 2019).
