Reasons for illicit drug use in people with schizophrenia: Qualitative study

Characterization of substance use in homeless patients with mental disorders

BACKGROUND

In Denmark, 42% of homeless people suffer from dual diagnosis, i.e. the co-occurrence of a substance use of alcohol and/or illegal substances and another psychiatric disorder. Dual diagnosis homeless patients often cause differential diagnostic difficulties and fail to receive effective treatment. A solid grasp of the role of substance use in these patients may inform the diagnostic decision and contribute to improve their treatment. Today, knowledge of these issues remains scarce. The purpose of this study was to explore substance use in homeless patients with mental disorders and their subjective perspectives on their substance use.

METHODS

44 homeless dual diagnosis patients were included in the study. They were examined in interviews focusing on their substance use and their subjective perspective on their substance use.

RESULTS

The most frequently used substances were cannabinoids (70.5%) and alcohol (45.5%), followed by cocaine, sedative/hypnotics, and amphetamine. The finding suggests that substance use in dual diagnosis homeless patients is a complex phenomenon with most patients (56.8%) using multiple substances. While substance use seems to contribute to keep the patients homeless, substance use was also reported to play an important role in coping with life on the streets by offering social contact and some relief from a desperate situation.

CONCLUSION

Substance use, mental disorder, and homelessness seem to be closely entangled, reinforcing each other and making it difficult to help these vulnerable patients. Diagnostic overshadowing may cause delays in adequate diagnosis and treatment of this group of patients.

Theoretical understanding of contextual motivations for sustained adolescent marijuana use in South Africa

Background

Although various reasons for adolescent marijuana use have extensively been explored, contextual factors that sustain the practice in settings where the plant is illegally cultivated, especially in South Africa, remain a grey area.

Aim

We aimed to explore the contextual factors of sustained adolescent marijuana use in two illicit marijuana-growing settings of the Ingquza Hill Local Municipality of South Africa, based on the differential opportunity theory (DOT) and subcultural theory (SCT).

Setting

The study was conducted in two illicit marijuana-growing communities in the Ingquza Hill Local Municipality of the Eastern Cape Province of South Africa.

Methods

Exploratory qualitative research, using focus group discussions approach, was conducted amongst 37 participants, four focus groups and in two communities in the Ingquza Hill Municipality of the Eastern Cape Province of South Africa. Purposive and snowball sampling techniques were used to select the communities and participants, respectively. The data were analysed using a thematic content analysis approach and presented under various themes.

Results

Nine themes, grouped under two broad factors, DOT influences (availability and affordability of marijuana, idleness and means of dealing with personal problems) and SCT influences (peer conformity, the pleasure derived from marijuana smoking, manipulation of appetite, health reasons, for higher cognitive function and addiction), emerged from the analysis.

Conclusion

As marijuana has been identified to be a gateway drug for the use of other illicit drugs, its sustained usage amongst adolescents poses a health challenge to the user, community and the country’s healthcare system at large. Hence, there is the need to intensify adolescent marijuana use prevention campaigns in illicit marijuana-growing contexts of South Africa, focussing on the differential opportunities and subcultural inclinations that promote the behaviour in those contexts.

Problematic Drug Use Among Outpatients With Schizophrenia and Related Psychoses

Background: Problematic drug use is common among psychiatric patients and is linked with poorer course and outcomes of illness. The aim of this study is to assess the prevalence of problematic drug use, and to explore its sociodemographic correlates and associations with health behaviors and outcomes among outpatients with schizophrenia and related psychoses in Singapore. Methods: Data from 397 individuals who were aged 21-65 years and were seeking treatment for schizophrenia and related psychoses in the outpatient clinics of a tertiary psychiatric hospital were analyzed. The Drug Abuse Screening Test (DAST-10) was used to assess problematic drug use. Information on sociodemographics, smoking status, alcohol use, symptoms severity and quality of life were collected. Multivariable logistic regressions were conducted to explore correlates and associations of problematic drug use. Results: The prevalence of problematic drug use was 5.8% (n = 23) in the sample, and 10.6% (n = 42) of the participants reported having problematic drug use and/or problematic alcohol use. More males than females reported having problematic drug use (p = 0.021), and also problematic drug and/or alcohol use (p = 0.004). Significant associations were observed between problematic drug use and smokers with nicotine dependence, and with physical health domain of quality of life. Individuals with greater symptom severity were approximately twice as likely to have problematic drug use and/or alcohol use. Conclusion: While the prevalence of problematic drug use in this sample population is relatively lower compared to other countries, there is a considerable number who might be at risk. Routine screening and close monitoring of drug use is recommended as part of psychiatric assessment, particularly among males and patients with nicotine dependence.

Considering the Microbiome in Stress-Related and Neurodevelopmental Trajectories to Schizophrenia

Early life adversity and prenatal stress are consistently associated with an increased risk for schizophrenia, although the exact pathogenic mechanisms linking the exposures with the disease remain elusive. Our previous view of the HPA stress axis as an elegant but simple negative feedback loop, orchestrating adaptation to stressors among the hypothalamus, pituitary, and adrenal glands, needs to be updated. Research in the last two decades shows that important bidirectional signaling between the HPA axis and intestinal mucosa modulates brain function and neurochemistry, including effects on glucocorticoid hormones and brain-derived neurotrophic factor (BDNF). The intestinal microbiome in earliest life, which is seeded by the vaginal microbiome during delivery, programs the development of the HPA axis in a critical developmental window, determining stress sensitivity and HPA function as well as immune system development. The crosstalk between the HPA and the Microbiome Gut Brain Axis (MGBA) is particularly high in the hippocampus, the most consistently disrupted neural region in persons with schizophrenia. Animal models suggest that the MGBA remains influential on behavior and physiology across developmental stages, including the perinatal window, early childhood, adolescence, and young adulthood. Understanding the role of the microbiome on critical risk related stressors may enhance or transform of understanding of the origins of schizophrenia and offer new approaches to increase resilience against stress effects for preventing and treating schizophrenia.

Drug use among Teenagers and Young Adults in Bhutan

BACKGROUND

Use, possession, and illegal transactions of controlled substances have increased in recent years in Bhutan. This study aimed to determine the national prevalence of ever drug use and identify its associated factors amongst teenagers and young adults.

METHODS

This study was conducted using data from the National Health Survey 2012 of Bhutan. The outcome variable of interest was ever drug use in teenagers and young adults. The questionnaire was developed following the WHO STEPwise approach to surveillance of non-communicable diseases (STEP). Univariate and multivariate logistic regression were performed to identify correlates of ever drug use.

RESULTS

The prevalence of ever drug use among teenagers and young adults was 3.2% (n = 672). The factors associated with ever drug use were: being men; being single; being in age group of 18-24 years; having a primary school, high school, monastic, university, or diploma education; being technicians or salespersons; feeling always lonely; having ever consumed alcohol, and having ever smoked.

CONCLUSION

Compared to the other countries in the WHO South-east Asia region, the prevalence of ever drug use in Bhutan is low. Use of other substances, including smoking and alcohol use, was associated with ever drug use. For greater effect, drug use prevention strategies should include prevention of smoking and alcohol use.

A qualitative evaluation of an ACT-based substance misuse treatment programme for service users within a secure mental health setting

Purpose

The purpose of this paper is to understand service users’ experience of a new acceptance and commitment therapy (ACT)-based substance misuse programme. The programme is designed for people in secure mental health services, presenting with complex mental health difficulties and co-occurring substance misuse problems.

Design/methodology/approach

A qualitative approach informed an exploratory pilot of this novel intervention. Service users completing a 16-week ACT programme were invited to participate in the current study. Out of the nine individuals enroled on the programme, six opted to take part in the exploratory pilot and completed semi-structured interviews following part 1 of the programme (eight weeks). Four of these participants proceeded into part 2 of the programme (eight weeks) and completed a further semi-structured interview.

Findings

The thematic analysis identified five main themes: “Increased awareness of personal values and the impact of substance use on values”, “Taking committed action towards values”, “Coping skills and the application of skills to manage difficult thoughts and feelings”, “Personal development” and “Use of metaphors/analogies”.

Research limitations/implications

A quantitative evaluation of clinical outcomes is recommended to gauge further programme effectiveness.

Practical implications

The findings provide preliminary support for the use of an ACT-based substance misuse programme in a secure mental health setting.

Originality/value

This study evaluates the use of a novel ACT-based substance misuse intervention with people in secure mental health care with co-occurring mental health and substance misuse difficulties. This paper provides an in-depth understanding of service users’ experience of participating in this new treatment programme.

Schizophrenia in high risk opioid users: A short communication on an autopsy study

The prevalence of schizophrenia among high risk opioid users was investigated as part of a wider investigation into opioid-related deaths. We found that over 6% of our sample of 312 decedents of opioid overdose had received a schizophrenia related diagnosis over a 36 month period prior to their death. This represents a near 8× increase on previously estimated period prevalence of schizophrenia in the general population. Though not conclusive, our findings raise questions about the extent to which opioid drugs are used by people with schizophrenia, and about how to best address high risk opioid use in people with schizophrenia.

Causal beliefs in people experiencing psychosis: The relationship to treatment accessed and the perceived helpfulness of treatment

PURPOSE

Research suggests that the way an individual understands a health difficulty can influence their subsequent behaviour. The aim of this study was to explore the psychometric properties of a new causal belief questionnaire for people who have experience of psychosis. We also planned to provide an overview of current causal beliefs within this group and to explore the relationship between these beliefs and the perceived helpfulness of treatment and the treatment accessed.

METHODS

Three hundred and eleven service-users with experience of psychosis completed a questionnaire designed to explore how they understand the cause of their difficulties. Additional information was collected about different aspects of treatment.

RESULTS

The results of the exploratory factor analysis indicated a two-factor solution comprising a psychosocial and biogenetic scale. Individuals in this study endorsed a variety of different causes, with an overall preference for psychosocial explanations. No relationships were established between beliefs and perceptions about the helpfulness of treatment. Individuals who had accessed cognitive behavioural therapy were more likely to endorse the psychosocial factor.

CONCLUSIONS

Individuals with psychosis consider a number of factors to be important in relation to the development of their experiences. These beliefs should be explored as part of the therapeutic process as this appears to be important to the individual and could potentially help inform treatment decisions.

PRACTITIONER POINTS

The causal belief questionnaire captured two underlying constructs relating to psychosocial and biogenetic causes. Individuals within this group endorsed a range of factors; however, they prefer psychosocial causes overall. There was an indication that some aspects of an individual's beliefs were associated with the treatment they accessed.

"I Believe I Know Better Even than the Psychiatrists What Caused It": Exploring the Development of Causal Beliefs in People Experiencing Psychosis

This study aimed to describe the causal beliefs of individuals experiencing psychosis, specifically exploring how they are developed and maintained. Individuals with experience of psychosis were recruited from mental health services for in-depth interviews. A thematic analysis was used to analyse transcripts and key themes were identified. Fifteen interviews were conducted. Individuals were engaged in the process of exploring explanations for their experiences and reported sophisticated models of causation. Participants described a change in their beliefs, with the cause of their experiences not immediately clear. Individuals generated their models via external (family, professionals) and internal (evaluative, positive affect) processes and reported differing levels of conviction in relation to their beliefs. Clinicians should take the opportunity to explore the causal beliefs of their service-users, as they are able to provide intelligent and thoughtful explanatory models. In particular, clinicians should be aware of the emotional impact of different aetiological models and their personal role in the development of a client's beliefs.

Risk factors of compliance with self-harm command hallucinations in individuals with affective and non-affective psychosis

Clinicians are often left with the difficult task of assessing and managing the risk of violent behaviors in individuals having command hallucinations, which may result in substantial rates of false positive or false negative. Moreover, findings on the association between command hallucinations and suicidal behaviors are limited. In an attempt to better understand compliance to this hallucinatory phenomenon, our objective was to identify the risk factors of compliance with self-harm command hallucinations. Secondary analyses from the MacArthur Study were performed on 82 participants with psychosis reporting such commands. Univariate logistic regression was used to examine the classification value of each characteristic associated with compliance with such commands. Seriousness and frequency of childhood physical abuse, a current comorbid substance use disorder, emotional distress, general symptomatology, history of compliance, and belief about compliance in the future were found to be significant risk factors of compliance with self-harm commands in the week preceding psychiatric inpatient. Multivariate analyses revealed that severity of childhood physical abuse, belief about compliance in the future, and a current comorbid substance use disorder were independent risk factors. The final model showed excellent classification accuracy as suggest by the receiver operating characteristic curve (AUC=0.84, 95% CI: 0.75-0.92, p<0.001). Our results suggest considerable clinical implications in regard to the assessment of risk of compliance to self-harm command hallucinations in individuals with psychosis.

Stuck in limbo: illicit drug users' experiences with opioid maintenance treatment and the relation to recovery

OBJECTIVE

The objective of this article is to gain insight into how individuals who frequent open illicit drug scenes experience opioid maintenance treatment (OMT) and investigate how this appears to affect their recovery processes.

METHOD

By means of the ethnographic method, one of the researchers spent time in an open illicit drug scene over a 1-year span, and gathered data on individuals who frequent the scene on a regular basis, and their experiences with OMT. The data are based on field notes and audiotaped interviews.

FINDINGS

Four themes emerged as relevant for the participants' experiences with OMT: 1) the loss of hope, 2) trapped in OMT, 3) substitution treatment is not enough, and 4) stigmatization of identity.

CONCLUSION

The participants found the OMT to be overruling and degrading. Several of the individuals from the illicit drug scene are part of the OMT programme, but as the treatment does not remove painful emotions, they supplement OMT with illegal substances, violate the OMT regulations, and run the risk of being excluded from the programme. In fear of losing the replacement opioid, they conceal parts of the addiction they seek treatment for and end up lying and cheating instead of exploring strategies for reducing and managing the addiction. The patients' relation to the OMT personnel is negatively affected by the need to hide a large portion of their issues. The result is a feeling of hopelessness, increased stigmatization, lack of control and being trapped between two worlds-in limbo, an intermediate state which interferes with the recovery process.

Understanding How People with Mental Health Difficulties Experience Substance Use

BACKGROUND

Quantitative studies dominate research exploring reasons for substance use and experiences of substance use by people with mental health difficulties. This limits the depth of understanding which can be gained about these experiences.

OBJECTIVES

In the present article, we synthesized current qualitative research in this area to provide enhanced theoretical knowledge of these experiences.

METHODS

Following a systematic literature search, we identified 12 studies which explored how people with mental health difficulties experienced using substances, and which met additional inclusion criterion. We used Noblit and Hare's metaethnographic approach to qualitatively synthesize these studies.

RESULTS

Synthesis led to the development of two themes; "substance use mediates acceptance and social inclusion" and "substance use provides perceived opportunities for control and power."

CONCLUSIONS/IMPORTANCE

The findings suggest that in the studies reviewed people's motivation for substance use was embedded in social and psychological contexts. It indicated that substance use could provide perceived benefits such as mediating the impact of mental health stigma, enabling the development of alternative identities, increasing their sense of power and providing opportunities for social inclusion. Mental health and substance use workers should therefore aim to develop alternative opportunities for people with co-occurring disorders to gain such benefits, and seek to challenge mental health stigma.

Can exploring natural recovery from substance misuse in psychosis assist with treatment? A review of current research

Substance misuse in people with psychosis presents significant problems, but trials of treatments to address it show little sustained advantage over control conditions. An examination of mechanisms underpinning unassisted improvements may assist in the refinement of comorbidity treatments. This study reviewed existing research on natural recovery from substance misuse in people with psychosis. To address this issue, a systematic search identified only 7 articles that fulfilled the criteria. Their results suggest that people with psychosis report similar reasons to change as do non-psychotic groups, although they did not clarify whether the relative frequencies or priority orders were the same. Differences involved issues relating to the disorder and the functional problems faced by this group: receipt of treatment for mental health difficulties, worsening of mental health difficulties, and homelessness. The current research on reasons for change in people with psychosis is sparse and has significant limitations, and as yet it offers little inspiration for new treatments. A more fertile source may prove to be a detailed investigation of successful substance control strategies that are used in self-management by this group.

Walking the fine line: self-reported reasons for substance use in persons with severe mental illness

Many theoretical models have been proposed to explain the relationship between severe mental illness (SMI) and substance use. Because many of these are contradictory quantitative American studies, a qualitative, exploratory study of a Scandinavian sample may offer a new perspective. The aim of the study is to explore reasons for substance use through analysis of the participants' experiences. A qualitative study with semistructured interviews was used. Purposeful sampling (N=11) of patients with substance use disorder (SUD) and SMI, who were included in assertive community treatment teams, was completed. Inclusion criteria are increased quality of life or increased general functioning, and decreased substance use, after a minimum of 12 months in treatment. Reasons given for using substances were categorized as (a) controlling the symptoms of mental illness, (b) counteracting medication side effects, or (c) balancing the ambiguity. The conclusion is that the study findings mainly support secondary substance use models in explaining the comorbidity of SMI and substance use. However, there is some support for the traditional self-medication hypothesis (SMH), iatrogenic vulnerability, and the supersensitivity model. This may be because the majority of the study participants reported having a mental illness with subsequent substance use. The expressed ambivalence to substance use also lends some support to bidirectional models.

Family history of schizophrenia as a risk factor for axis I psychiatric conditions

People with first-degree relatives with schizophrenia are at an elevated risk of developing the disorder themselves. High rates of psychotic symptoms in non-psychotic disorders, high rates of comorbidity in psychotic disorders, and diversity of outcomes following psychosis-risk states together suggest that this vulnerability may be for psychiatric conditions in general, not limited to schizophrenia. In this study, data from the National Survey of American Life (NSAL) were used to examine the association between having a first-degree relative with schizophrenia and the lifetime development of a range of non-psychotic axis I psychiatric disorders using adjusted odds ratios. Having a relative with schizophrenia was associated with increased risk for most non-psychotic psychiatric conditions examined, including those expected to be associated with schizophrenia (affective, anxiety, and substance use disorders) and those not expected (bulimia, disorders of childhood onset), excluding respondents with lifetime psychotic symptoms and controlling for demographic factors. Family history of schizophrenia among this predominantly African-American and Afro-Caribbean sample appears to be a risk factor for a range of axis I diagnoses, supporting a continuous rather than categorical nature of psychiatric vulnerability. Future studies should examine whether these associations are due to genetic or environmental factors, or both.

[Motivational interviewing in psychiatry]

Motivational Interviewing and associated communication techniques and intervention methods have been widely applied in patients with substance use disorder and other psychiatric disorders in the last twenty years. Intensive research on effectiveness and underlying mechanisms as well as the increasing efforts to apply MI in other psychiatric disorders has lead to a large number of scientific publications in this field. MI has been shown to be effective in situations where the patient's ambivalence seems to impede the therapeutic process. Communication skills and the ability of the care taker to induce the so called "change talk" by the patient play a particularly important role and correlate with the positive effects of MI. Those groups of patients in which other factors than ambivalence affect the therapeutic process seem to benefit much less from this intervention method. MI hallmarks the substantial change that gradually took place during the last two decades in caretakers' attitude towards patients with dependence and other psychiatric patients: away from "prescriptive" towards "supportive" treatment and communication style. Therefore, it seems to be reasonable to implement the basics of MG in the training curricula for psychiatrists.
