Effectiveness of interventions for children and adolescents with autism spectrum disorder in high-income vs. lower middle-income countries: An overview of systematic reviews and research papers from LMIC

Attitudes Toward and Usage of Evidence-Based Mental Health Practices for Autistic Youth in Bangladesh and Germany: A Cross-Cultural Comparison

The implementation of evidence-based practices (EBPs) for autistic youth is a critical concern worldwide. Research examining factors facilitating the implementation of EBPs found that providers' attitudes are an important factor. In this study, we evaluated cross-cultural differences in attitudes toward and use of EBPs. We tested socio-demographic factors as predictors of attitudes, and attitudes as predictors of EBPs use among mental health professionals working with autistic youth in Bangladesh and Germany. We used purposeful sampling. Two-hundred-ninety-two professionals who worked in a clinical setting responded to the survey and fulfilled the inclusion criteria (101 in Bangladesh, 191 in Germany). Participants were asked to respond to nine subscales of the Evidence-Based Practice Attitude Scale-36 (EBPAS-36), to indicate which of nine types of treatments they used, and to provide sociodemographic data. Measurement invariance across countries could be established for four subscales of the EBPAS-36. Comparative analyses of attitudes showed that professionals in both countries were open to using EBPs, but German practitioners were more likely to use EBPs when they appealed to them. By contrast, Bangladeshi professionals claimed to be more likely to adopt an EBP when required and to be more willing to learn EBPs to enhance job security. The relationship between caseload and attitudes varied between countries. A broader variety of EBPs was used in Germany. The findings highlight the importance of considering country-specific factors when implementing EBPs. Directions for conducting comparative studies on mental health professionals' attitudes towards EBP including methodological considerations are discussed.

Evaluation of the effectiveness of behavioral interventions for autism spectrum disorders: A systematic review of randomized controlled trials and quasi-experimental studies

The objective of this research was to assess the efficacy of behavioral therapy interventions in the treatment of autism spectrum disorders (ASD). The study utilized the PubMed and Embase databases to locate randomized controlled trials, quasi-experimental treatment studies, and randomized clinical trial comparisons. The experimental group received treatment based on an applied behavioral approach, such as PECS, DTT, PRT, TEACCH, ESDM, and EIBI. After examining seventeen studies, the researchers found that each type of behavioral intervention had a positive impact. Naturalistic protocols that employed PRT and PECS improved ASD symptoms in general, despite their targeting of particular cognitive domains such as language. ESDM enhanced receptive language, particularly in preschool-aged children. Structured and integrated interventions, like EIBI and TEACCH, improved overall adaptive functioning. Combining DTT with a TEACCH program produced greater benefits in linguistic, affective-social, and personal autonomy domains. However, there is a scarcity of high-quality research available on behavioral interventions for ASD. Further comparative studies are necessary to identify cost-efficient interventions. For example, PRT and PECS significantly improved social communication skills in only 15-40 hours over six months. The authors emphasized the need for continued research and the application of evidence-based interventions in specialized settings.

Nurturing the Positive Mental Health of Autistic Children, Adolescents and Adults alongside That of Their Family Care-Givers: A Review of Reviews

The rising prevalence of autism internationally has been accompanied by an increased appreciation of the poorer mental health experienced by people with this condition and also of their family care-givers. In particular, higher incidences of anxiety and depression are reported in high-income nations and these conditions are likely to be under-recognised and under-reported in lower-resourced regions or countries. Mainstream mental health services seem to be ill-equipped to respond adequately to the needs of autistic persons and their care-givers. This literature review of 29 recently published reviews covering nearly 1000 journal articles summarises the insights and strategies that have been shown to promote the mental health and emotional wellbeing of autistic persons. In particular, a focus on family-centred, community-based supports is recommended that aim to enhance social communication, extend social connections and promote an individual's self-esteem, self-determination and social motivation. These low-cost interventions are especially pertinent in low-resourced settings, but they can be used internationally to prevent mental illness and assist in the treatment of anxiety and depression in autistic persons and their family carers. The priority is to focus on primary-care responses with cross-sectoral working rather than investing in high-cost psychiatric provision.

Psychosocial interventions for autistic children and adolescents delivered by non-specialists in low- and middle-income countries: a scoping review

Background

Most autistic individuals reside in low- and middle-income countries (LMIC) and have limited access to medical providers and specialists. Support for delivery of psychosocial interventions by non-specialists is growing to address this mental health care gap. This scoping review involved a systematic analysis of studies of non-specialist delivered psychosocial interventions for children and adolescents diagnosed with autism and living in low- and middle-income countries.

Methods

The primary objective of this review was to identify psychosocial interventions for autistic children and adolescents in LMIC delivered by non-specialists (parent, teacher, peer, community, multi-level) and to summarize resulting effects on targeted outcomes. The search strategy was completed in four databases with predetermined inclusion and exclusion criteria. The systematic search generated 3,601 articles. A total of 18 studies met inclusion/exclusion criteria. Data extraction was completed, and results summarized by; (1) participant sample; (2) intervention procedures; (3) implementation by non-specialists; (4) effect on evaluated outcomes; and (5) assessment of risk of bias. Studies examined a range of child and adolescent outcomes including assessment of communication skills, social skills, motor skills, functional and adaptive behaviors, emotional regulation, attention and engagement, sensory challenges, depression, anxiety, and quality of life. Several studies also evaluated intervention effects on family relationships, parent/caregiver stress and parent/caregiver mental health.

Results

Collectively, the 18 studies included a total of 952 ASC participants ranging in age from 2 to 16 years. Of the included studies, 8 studies were parent/caregiver-mediated, 1 study was peer-mediated, 2 studies were teacher-mediated, and 7 studies included multi-level non-specialist mediated components. Effects on evaluated outcomes are reported.

Conclusion

Non-specialist delivered interventions for autistic children and adolescents are effective for an array of outcomes and are particularly well suited for low- and middle-income countries. Implications for future research are discussed.

Attitudes Towards Evidence-Based Practice of Professionals Working with Children and Adolescents with Autism Spectrum Disorder in Bangladesh

Like in many lower-middle-income countries (LMIC), progress in implementing evidence-based practices (EBPs) for children with autism spectrum disorder (ASD) has been slow in Bangladesh. This cross-sectional study examined professionals' attitudes towards evidence-based practice (EBP) for children and adolescents with ASD and explored how providers' demographic factors are related to attitudes to and adoption of EBPs in Bangladesh. The sample consisted of 150 mental health professionals and special teachers from the urban area of Dhaka. Attitudes were assessed by the Evidence-based Practice Attitude Scale-36. Findings indicated that professionals have favorable attitudes towards EBP. Their attitudes varied depending on service settings (public clinical, private clinical, and special school) and caseload per year. Professionals who work in private and special school settings claimed to be more willing to adopt an EBP when required and perceived a higher fit of EBPs and their work than those in public clinical settings. The number of different EBPs used also differed by service setting. Every type of intervention (except medication) was used by more professionals in special schools than in private and public clinical settings. Many professionals reported few barriers to the implementation of EBPs. These findings indicate conditions that are often conducive to the implementation of EBPs. However, these results do not reflect the situation in rural areas, in which poverty is more widespread and the number of specialized professionals is low.
