Evaluation of a Low-Intensity Online Intervention (LiON) for Reducing Distress and Mental Health Symptoms in Young People.

PURPOSE: Enhancing young people's mental health is crucial given that most adult mental disorders develop before age 24 years. However, it is unclear whether low-intensity interventions delivered online can be effective. This study aimed to provide preliminary evidence on whether a low-intensity online intervention (LiON) can effectively lower young people's distress levels and mental health symptoms. METHODS: We compared the preintervention and postintervention changes in distress level and severity of depression and anxiety symptoms in 137 young people aged 15-24 years who used the LiON service with the three-month changes in a 1:1 propensity score-matched control group of community young people who did not use the service. They participated in one of the following modules for the first time: (1) sleep and relaxation, (2) stress-coping, and (3) problem-solving. RESULTS: Participants who received LiON intervention (mean age 22.88 [standard deviation 3.67] years, 65.7% female) showed significantly greater reductions in distress level (Cohen's f2: 0.079), as well as the severity of depressive symptoms (Cohen's f2: 0.056) and anxiety symptoms (Cohen's f2: 0.044) compared to the control group. DISCUSSION: The findings suggest that the LiON intervention has the potential to effectively reduce distress and mental health symptoms in young people. Future research should aim to confirm these findings through randomized controlled trials and explore the cost-effectiveness of the intervention.

Comorbidity of autism spectrum and attention deficit/hyperactivity disorder symptoms and their associations with 1-year mental health outcomes in adolescents and young adults.

Autism spectrum (ASD) and attention deficit/hyperactivity disorders (ADHD) share genetic, neurological, and behavioural features. However, related research in Asia is limited. We collected self-reported ASD and ADHD symptoms from 2186 Hong Kong adolescents and young adults aged 15-24 years, among whom, 1200 provided 1-year data on mental health-related outcomes. Comparative and network analyses were performed. Rating scale cutoff scores were used to divide participants into ASD, ADHD, comorbid, and control groups. The prevalence rates of ASD, ADHD, and comorbidities in Hong Kong were 13.3 %, 10.6 %, and 2.7 %, respectively. Compared with the control group, the comorbid group experienced more psychotic-like experiences (PLEs), the ASD group had poorer functioning, and the ADHD group had higher depression and anxiety symptoms and a lower quality of life after 1 year. The ability to switch attention, preference for routines and difficulty with change, and problems with organisation and planning were positively associated with depressive symptoms, forgetfulness and working memory issues with anxiety symptoms, and heightened sensory input and difficulties in sustaining attention and task completion with PLEs after 1 year. Our findings provide insight into support strategies to address the needs of young Asians to improving their well-being and long-term outcomes.

Effects of a culturally adapted counselling service for low-income ethnic minorities experiencing mental distress: a pragmatic randomised clinical trial.

BACKGROUND: Culturally competent early mental health interventions for ethnic minorities (EMs) with no formal diagnoses are needed. OBJECTIVES: To determine whether 8-12 weeks culturally adapted counselling (CAC) is better than waiting (waitlist (WL) group) to reduce depressive and anxiety symptoms and stress levels among EMs with elevated mental distress. METHODS: Hong Kong EMs with mild and above-mild mental distress were randomly assigned to CAC or WL in this pragmatic, randomised, WL-controlled trial. The CAC group received the intervention after randomisation and the WL group received the intervention after 8-12 weeks (T1). The prespecified primary outcomes were depressive and anxiety symptoms and stress levels measured by the Depression, Anxiety and Stress subscales of the Depression, Anxiety and Stress Scale (DASS-D, DASS-A and DASS-S, respectively) at postintervention (T1, 8-12 weeks). FINDINGS: A total of 120 participants were randomly assigned to either CAC (n=60) or WL (n=60), of whom 110 provided primary outcome data. At T1, CAC led to significantly lower depressive and anxiety symptom severity and stress levels compared with waiting, with unstandardised regression coefficients of -8.91 DASS-D points (95% CI -12.57 to -5.25; d=-0.90),-6.33 DASS-A points (95% CI -9.81 to -2.86; d=-0.68) and -8.60 DASS-S points (95% CI -12.14 to -5.06; d=-0.90). CONCLUSIONS: CAC clinically outperformed WL for mild and above-mild levels of mental distress in EMs. CLINICAL IMPLICATIONS: Making CAC routinely available for EMs in community settings can reduce healthcare burden.

The Hong Kong youth epidemiological study of mental health (HK-YES)-A population-based psychiatric epidemiology study of youth mental health in Hong Kong: A study protocol.

AIM: Young people in Hong Kong have been facing numerous population-level events over the past year, including social unrest and the COVID-19 pandemic. Representative data concerning the mental health of youths, however, is limited. The Hong Kong Youth Epidemiological Study of Mental Health (HK-YES) is commissioned to provide the first representative prevalence estimates and correlates of mental disorders among young people in Hong Kong. It will also examine the help-seeking behaviours, treatment rates, quality of life, and functional outcomes of the young people. More importantly, the direct and indirect economic costs of mental disorders in youths will be estimated. METHODS: A total of 4500 community-dwelling participants aged 15-24 years from Hong Kong will be surveyed. Participants will be selected using a multistage stratified sampling design to provide representative estimates of the youth population in Hong Kong. All interviews will be conducted using computer-assisted personal interviewing methods for assessments covering areas of psychiatric diagnoses, symptomatology, functioning, quality of life, disability, service utilization, health economic costs of mental disorders, and sociodemographic and lifestyle characteristics. A population-weighted prevalence will be estimated using survey weights. Methods such as multivariate logistic and linear regression analyses will be used to calculate the risks and odds of factors that might be associated with different mental disorders. CONCLUSION: As the first population-based youth study in Hong Kong, HK-YES collects extensive and representative data on different mental conditions and their associated factors among young people. The information gathered will be important for future planning on youth mental health services in Hong Kong and will offer the opportunity for a more meaningful comparison of data with other youth populations.

Visual-stress-related cortical excitability as a prospective marker for symptoms of depression and anxiety in young people.

Visual stress is thought to reflect cortical excitability and has been associated with many neurological, neuropsychiatric, and neurodevelopmental conditions. However, its relationships with symptoms of depression and anxiety have not yet been elucidated. We conducted two separate studies to first examine visual stress in a longitudinal community sample of 104 participants (aged 12-24) in association with prospective symptoms of depression, anxiety, and distress after 3 months, and subsequently in a cross-sectional epidemiological sample of 530 participants (aged 15-24) to validate its associations with current mood and distress symptoms. The Pattern Glare Test was used to examine visual stress to three grating patterns with the spatial frequencies (SF) of 0.3, 2.3, and 9.4 cycles per degree (cpd). Other known factors of mental health, including functioning, as well as resilience, hopelessness, and loneliness, were also assessed at baseline. In both studies, we showed that perceptual distortions were highest toward the pattern with mid-SF (2.3 cpd). Multiple linear regression analyses revealed that greater visual stress was significantly associated with not only baseline but also 3-month symptom outcomes, even when accounting for age, years of education, days of no functioning, resilience, hopelessness, and loneliness. Our findings suggest the importance of visual stress in understanding and predicting poor mental health outcomes. As mental health can lead to far-reaching consequences that extend to adulthood, our findings may inform state-of-the-art innovative strategies for the prediction of poor mental health outcomes and suggest visual stress as a potential marker for early risk detection among young people.

Assessing anxiety among adolescents in Hong Kong: psychometric properties and validity of the Generalised Anxiety Disorder-7 (GAD-7) in an epidemiological community sample.

BACKGROUND: The development of a valid and simple-to-use self-administered tool in Asian adolescents for clinical screening and intervention remains limited. The present study assessed the psychometric characteristics and validity of the Generalised Anxiety Disorder Scale-7 (GAD-7) among adolescents in Hong Kong. METHODS: Epidemiological data from 3,261 Hong Kong adolescents aged 15 - 24 years were analysed for the construct validity, criterion validity, concurrent validity, and Rasch Model. All analyses were age- and gender-weighted according to the distributions of Hong Kong's general population. RESULTS: The GAD-7 showed high internal consistency and strong fit to the one-factor structure. The best cut-off value was set at 7 or more. Regression models found that the total scores of the scale were positively associated with symptoms of depression and hypomania, schizotypal personality and alcohol dependence. Rasch model analysis found that the separation index was 2.18 and 16.51 for the respondents and items, respectively and all residual pairs had small correlation coefficients (i.e., < 0.3). CONCLUSIONS: All psychometric findings presented in this study support the use of the GAD-7 as a legitimate measure of anxiety severity. A cut-off score of 7 should indicate a potential diagnosable condition in Asian adolescents, which requires our attention but should not be used as a formal diagnostic screening tool. The findings revealed the local dependence of the items of the GAD-7 and that the scale can separate respondents into at least two groups and items into numerous groups according to the separation index.

Social context and loneliness in an epidemiological youth sample using the Experience Sampling Method.

BACKGROUND: Previous research has shown the relationship between loneliness and affect, as well as the relationship between trait loneliness and state loneliness. However, none has investigated how social context affects the association between loneliness and affect. The current study aims to examine the association between trait loneliness, state loneliness and momentary affects in different social contexts. METHODS: Participants aged 15-24 were randomly recruited from a Hong Kong epidemiological study to participate in an Experience Sampling Method (ESM) study. The group was divided in two based on the mean trait loneliness score (UCLA Loneliness Scale) at baseline. State loneliness, momentary positive (PA) and negative affect (NA) and social context were assessed using ESM. Multilevel logistic regression was used to analyze the association between momentary affect, state loneliness and trait loneliness in various social contexts. RESULTS: HL (high lonely) and LL (low lonely) groups consisted of 79 participants (44.6%) and 98 participants (55.4%) respectively. HL group had lower PA and higher NA, as well as a higher state loneliness than LL group. HL group had a lower state loneliness when being with intimate company compared to alone. LL group only had a higher PA when being with intimate company compared to non-intimate company and alone respectively. CONCLUSION: Adolescents with high level of trait loneliness experienced higher PA, momentary loneliness and lower NA compared to those with low level of trait loneliness. The quality of social company is crucial in allowing one to experience different degrees of PA and momentary loneliness.

LevelMind@JC hubs-a novel community-based youth mental wellness early intervention in Hong Kong: An evaluation of stakeholders' perceptions and experiences.

OBJECTIVES: LevelMind@JC youth mental wellness hubs have been launched as a novel early intervention initiative to mitigate the inevitable youth mental health problems in Hong Kong in 2019. The present study investigated the perceptions and experiences of these hubs amonst three key stakeholders, namely hub youths, hub carers of youths and hub staff. METHOD: An online survey assessing the perceptions and experiences of hubs on 6 major domains (e.g., youth-friendly and nonstigmatizing characteristics) was administered to three stakeholders in December 2020. Seventy-one hub youths (12-35 years old), 18 hub carers (30-64 years old) and 25 hub staff (24-59 years old) completed the survey. RESULTS: On a 5-point Likert scale with higher ratings representing better outcomes, all three stakeholders reported above-average ratings on their overall satisfaction of hub experiences (hub youths: mean = 4.4, SD = 0.6; hub carers: mean = 4, SD = 0.8; hub staff: mean = 3.8, SD = 0.6). In addition, hub youths and hub carers reported above-average ratings on youth-friendly and nonstigmatizing characteristics regarding hubs (mean >=4.2). CONCLUSIONS: The present findings suggest that the key stakeholders are generally satisfied with and show support to the youth-friendly, empowering and nonstigmatizing LevelMind @JC hubs. These findings along with the suggestions for hub improvement made by the stakeholders highlight the importance of taking cultural values into consideration whilst planning for mental services. More importantly, clinical implications are also highlighted which give insight for the development and implementation of a scalable, effective, and replicable early community intervention for psychiatric practise pertaining to youth mental health.
