Influence of Biogenetic Explanations of Mental Disorders on Stigma and Help-Seeking Behavior: A Systematic Review and Meta-Analysis.

BACKGROUND: Biogenetic causal explanations of mental disorders are commonly used for public education and campaigns. However, the influence of biogenetic explanations on the ideas about and attitudes toward mental illness is unclear. We examined the influence of biogenetic explanations on attitudes toward mental disorders using a meta-analytic method accompanied by subgroup analyses. METHODS: The protocol for this meta-analysis was registered in PROSPERO (CRD42020158656) in March 2020. Experimental and correlational studies were analyzed separately. Five outcome measures related to attitudes toward mental disorders were included: 'attitude toward help-seeking,' 'blame,' 'perceived dangerousness,' 'prognostic pessimism,' and 'social distance.' Subgroup analyses were performed for the type of mental disorder, population, and geographic region for which a biogenetic explanation was provided. RESULTS: A total of 44 studies were included, of which 24 were experimental and 20 were correlational. A positive attitude toward help-seeking was associated with having a biogenetic concept (d = 0.43; 95% confidence interval [CI], 0.18 to 0.67; P < 0.001) in general population and in Eastern countries in particular. Although a biogenetic explanation was associated with a decreased level of blame (d = -0.20; 95% CI, -0.38 to -0.02; P = 0.029) in the general population, it was also associated with significantly higher levels of perceived dangerousness (d = 0.13; 95% CI, 0.03 to 0.23; P = 0.008). A tendency toward a higher level of prognostic pessimism and social distance was associated with a biogenetic concept of mental disorders although there was no statistical significance. CONCLUSION: Having a biogenetic concept of the cause of mental disorders was related with a positive attitude toward help-seeking, particularly in the general population and individuals living in Eastern countries. Providing a biogenetic explanation decreased blame toward individuals with mental illness but was associated with increased perceived dangerousness and prognostic pessimism. Therefore, although a biogenetic explanation promotes public use of mental health services, it should be carefully applied to avoid an increase in negative thoughts, such as that mental illness is biologically irreversible and untreatable.

Perceived barriers to psychiatric help-seeking in South Korea by age groups: text mining analyses of social media big data.

BACKGROUND: The psychiatric treatment gap is substantial in Korea, implying barriers in seeking help. OBJECTIVES: This study aims to explore barriers of seeing psychiatrists, expressed on the internet by age groups. METHODS: A corpus of data was garnered extensively from internet communities, blogs and social network services from 1 January 2016 to 31 July 2019. Among the texts collected, texts containing words linked to psychiatry were selected. Then the corpus was dismantled into words by using natural language processing. Words linked to barriers to seeking help were identified and classified. Then the words from web communities that we were able to identify the age groups were additionally organized by age groups. RESULTS: 97,730,360 articles were identified and 6,097,369 were included in the analysis. Words implying the barriers were selected and classified into four groups of structural discrimination, public prejudice, low accessibility, and adverse drug effects. Structural discrimination was the greatest barrier occupying 34%, followed by public prejudice (27.8%), adverse drug effects (18.6%), and cost/low accessibility (16.1%). In the analysis by age groups, structural discrimination caused teenagers (51%), job seekers (64%) and mothers with children (43%) the most concern. In contrast, the public prejudice (49%) was the greatest barriers in the senior group. CONCLUSIONS: Although structural discrimination may most contribute to barriers to visiting psychiatrists in Korea, variation by generations may exist. Along with the general attempt to tackle the discrimination, customized approach might be needed.
