A comparative study of socio-demographic and substance use correlates in early-onset psychosis

Substance use patterns in an adolescent psychiatric unit in Johannesburg, South Africa

Background

Substance use among adolescents carries a significant public health and socioeconomic burden with potential long-term consequences for the adolescent substance user (SU). Adolescents with mental health challenges are vulnerable to substance use and substance use worsens outcomes in this population.

Aim

This study aimed to describe the substance use patterns among inpatients admitted to a specialised tertiary adolescent inpatient unit in Johannesburg over a 4-year period.

Setting

This study was conducted at the Tara H. Moross Centre (Tara Hospital), in Johannesburg in the Gauteng province of South Africa.

Methods

This was a retrospective comparative record review of all patients admitted to the adolescent unit over the 4 years.

Results

A lifetime history of substance use was documented in 44.1% (n = 52) of the 118 patient's records included in the final analysis. Cannabis was the most frequently used substance (n = 36, 69.2%). There were significant differences between the SU and substance nonuser groups regarding family structure (p = 0.012), family history of substance abuse (p = 0.046) and conflict within the family (p < 0.001).

Conclusion

The high prevalence of substance use in this sample demonstrates the dual burden of mental health disorders and substance use in an adolescent treatment programme in Johannesburg. Primary caregiver burden and relational difficulties within the family unit should be observed for planned multidisciplinary interventions.

Contribution

The findings of this review provide an update on the pattern and prevalence of substance use among this adolescent mental healthcare user group, highlighting potential therapeutic targets.

The association of cognitive impairment with quality of life and functional impairment in Ugandan first-episode psychosis patients: a cross sectional study

INTRODUCTION

Cognitive impairment is common in first-episode psychosis patients and often associated with poor quality of life and functional impairment. However, most literature on this association is from high income countries and not low resource countries like Uganda. We aimed to determine the association between cognitive impairment with quality of life and functional impairment in Ugandan first-episode psychosis patients.

METHODS

At Butabika national psychiatric hospital of Uganda, we enrolled 94 first-episode psychosis patients aged 18-60 years with a confirmed first-episode of psychosis and no previous treatment with antipsychotic medication. Neuropsychological assessment was performed using the MATRICS consensus cognitive battery (MCCB). Quality of life and functional impairment were assessed using the brief version of the World Health Organisation Quality of Life scale (WHOQOL-BREF) and the MINI International Neuropsychiatric Inventory (MINI) respectively. Linear regression analyses determined the association between impairment in different cognitive domains with various quality of life and functional impairment domains while controlling for age, gender and level of education.

RESULTS

High scores in the reasoning and problem solving cognitive domain were associated with better quality of life in the psychological domain of WHOQOL-BREF (p = 0.029). For functional impairment, high cognitive scores in the domains of speed of processing (p = 0.018), reasoning and problem solving (p = 0.015), working memory (p = 0.017) and visual learning and memory (p = 0.002) were associated with psychosis "having a greater impact on other members of the family" on the MINI. Higher scores in the social cognition domain were associated with "less aggressive and disruptive behaviour" (p = 0.003).

CONCLUSION

Cognitive impairment in Ugandan first-episode psychotic patients is associated with both poorer quality of life and functional impairment. Remediation of cognitive function may be a plausible intervention to improve outcomes in Ugandan first-episode psychosis patients.

Insights about Cannabis and Psychosis Using Video Games for Young People with a First Episode of Psychosis, particularly those from Black Racialized Backgrounds: Study Design

Background

Cannabis use disorder among young people with a first episode of psychosis contributes to relapse, hospitalization, and impaired functioning. However, few studies have examined what young people with early phase psychosis, particularly those from Black racialized communities, understand or appreciate about this relationship, even though they may be at risk. There are no formally tested knowledge translation strategies that disseminate these research findings for young people with emerging psychosis from Black racialized communities.

Objective

This study aims to conceptualize what young people with early phase psychosis/cannabis use disorder understand about the relationship between cannabis and psychosis, focusing on people from racialized backgrounds. This study also aims to assess whether the knowledge translation product, the “Back to Reality Series,” increases awareness of the impact of cannabis use on psychosis from the perspectives of young people with emerging psychosis and cannabis use disorder from Black African and Caribbean communities.

Methods

Qualitative analysis will reveal themes from qualitative interviews about cannabis and psychosis from the perspectives of young people with emerging psychosis and cannabis use disorder from Black African and Caribbean communities. Perceptions before and after exposure to the Back to Reality Series will be qualitatively analyzed. A control game will be used for comparison, and scores on a quiz after playing the Back to Reality Series will be quantitatively analyzed to establish whether the Back to Reality Series raises awareness of the effects of cannabis on psychosis. An advisory council involving young people from Black communities, family members, and clinicians will bring community perspectives to this research.

Results

We began recruiting participants for this study in September 2021. We will complete data collection on demographic and clinical factors, qualitative interviews, and quantitative assessments of the Back to Reality Series.

Conclusions

The voices of young people from racialized backgrounds will generate preliminary data to inform early psychosis programs, addressing cannabis use in this population. The findings may advance the use of a new knowledge translation product that deals with gaps in knowledge about cannabis use for people experiencing early phase psychosis, particularly those from racialized communities.

Comparison of antipsychotic naïve first-episode psychosis patients and healthy controls in Uganda

INTRODUCTION

The risk factors for a first episode of psychosis in low and middle-income countries (LMICs) are not well described. The study compared the association of different risk factors in patients with first-episode psychosis patients and healthy controls from an LMIC context.

METHODS

A comparative, descriptive, cross-sectional study was performed in antipsychotic naïve first-episode psychosis patients and healthy controls at the National referral hospital in Uganda. Standardized tools were used to assess sociodemographic (e.g., age, sex, socioeconomic status) and clinical (e.g., childhood trauma, quality of life) variables. First episode psychosis participants were compared to healthy controls in terms of sociodemographic and clinical variables, and logistic regression was used to determine predictors of FEP.

RESULTS

Our final sample included 198 antipsychotic naïve first-episode psychosis participants and 82 controls. Most participants were female (68.5%) with a mean age of 29.4 years. After adjusting for age and sex, FEP patients when compared to controls were less likely to be female [AOR 0.18 (95%CI 0.03-0.85; p = .031)], more likely to have experienced emotional abuse [AOR 1.30 (95%CI 1.02-1.65; p = .032)] and more likely to have a poor quality of life [AOR 0.93 (95%CI 0.89-0.97; p = .002)].

DISCUSSION

The risk factors for a first episode of psychosis in this low and middle-income population were like those described in high-income countries. Further studies on interventions to prevent the transition to psychotic disorders in this sub-groups of patients are recommended. Also, the use of specialized early intervention services in improving the quality of life needs to be evaluated.

Early onset psychosis and cannabis use: Prevalence, clinical presentation and influence of daily use

Most of the studies examining the impact of cannabis use in first episode psychosis (FEP) have been carried out in samples with adult-onset FEP. Data in persons with early onset psychosis (EOP) is scarce. The aims of the study were: To describe the prevalence of lifetime cannabis use, current use, and daily use in patients with EOP compared to healthy controls. To study the differences in clinical presentation between cannabis users and non-users. To examine the risk of presenting an EOP associated with cannabis use and the effect of doses and age of onset of use. An observational cross-sectional study was performed in 90 EOP cases and 62 healthy controls, aged between 7 and 17 years. Our results show a higher prevalence of lifetime use (p = 0002), current use (p < 0.001), and daily use (p < 0.001) in EOP cases in comparison with healthy controls. Regarding clinical presentation, we did not find significant differences in any subscale of the Positive and Negative Syndrome Scale (PANSS). Non-user patients presented more severe depressive symptoms (p = 0002) and worse social functioning than cannabis users (p = 0026). Compared with subjects who never used cannabis, the risk of an EOP was significantly higher for those with a lifetime use (OR = 2.88, p = 0.002)current use (O.R = 6.09, p < 0001), and especially in those with daily use (O.R = 42.77, p = <0001). We found a higher risk of EOP in patients that have used cannabis before 15 years of age. In conclusion, it is necessary to develop early- detection and specific treatment programs for adolescents with cannabis use.

Substance use in adolescents with mental illness in Durban, South Africa

Comorbid substance use in adolescents with mental illness is often an indicator of poor treatment outcome. This study aims to determine the prevalence of, and associated risk factors for, substance use in adolescents with mental illness attending a mental health service. Data was collected from hospital records of 162 adolescents, using a structured data sheet, over a two-year period. Substance use was more significant in older adolescents and those with severe mental illness. Sixty-two (38.3%) adolescents used substances. Thirty-seven (38.1%) male adolescents reported substance use compared to 25 (38.5%) female adolescents. Alcohol was the most commonly used substance (n = 48; 29.6%), followed by cannabis (n = 32; 19.8%). There were significant direct associations between substance use and history of abuse or neglect, forensic history, educational setting, admission status, and the psychiatric diagnoses of schizophrenia, other psychotic disorders, and bipolar mood disorder. Inverse associations were found between substance use and adjustment disorders, attention deficit hyperactivity disorder, and intellectual disability. The results of this study indicate an urgent need for substance misuse programmes for at risk youth, and the introduction of dual diagnosis intervention programmes in this age group.
