    Study Notes

    Clinical Mental Health Investigating Studies

    • Evidence-based medicine is a revolt against tradition and unsupported clinical intuition
    • Evidence-based practice establishes a hierarchy of evidence
    • Randomised controlled trials (RCTs) prioritized by funders, reviewers, and guideline developers as the gold standard for research
    • RCTs aim for fair comparisons, unaffected by initial differences between groups

    Intervention Development

    • Interventions should address clinical problems with demonstrable unmet need, considering the relevant population
    • Existing evidence, adaptable interventions, and stakeholder views (service users, carers, clinicians) are important
    • Programme theories underpin interventions, explaining how they achieve change
    • Detailed intervention content, delivery methods, and contexts need to be specified

    RCTs in Psychosocial Interventions

    • RCTs are recommended for developing and testing psychosocial interventions
    • Key steps include developing theoretical frameworks, assembling relevant evidence, adapting or incorporating elements, testing feasibility and acceptability, and conducting definitive trials and implementation studies.

    Complex Interventions

    • Complex interactions are often developed by enthusiastic service leaders
    • Stages of development include feasibility assessment for intervention and evaluation design, developing or identifying interventions, core elements, engagement of stakeholders/relevant parties, refining interventions, implementation and evaluation
    • Programme theories are crucial for interventions, describing intended causal links between intervention and outcomes

    Theories of Behavior Change

    • Theories of behavior change are frequently used frameworks in intervention development
    • Studies often adapt these frameworks to specific contexts
    • They are key to grant applications and major studies, often incorporating health psychologists.

    Limitations of Trials

    • Trials are slow, taking 15+ years to reach definitive evidence
    • Contextual factors (e.g., treatment content) influence outcomes compared to interventions
    • Interventions delivered to entire service areas or healthcare systems require special consideration and thorough implementation planning

    RCTs in Current Mental Health Research

    • RCTs are crucial for testing interventions (e.g., drugs) and evaluating effectiveness
    • They are the standard for CBT and third-wave psychological treatments
    • Considerations include manualizing interventions, monitoring fidelity, and assessing cost-effectiveness

    Cluster Randomised Trials

    • Randomisation occurs at higher levels (e.g., teams, caseloads) for interventions impacting groups
    • Useful when individual randomisation is challenging
    • Researchers must account for challenges like group size and logistics of pre-randomisation assessment

    Quasi-Experiments and Naturalistic Studies

    • Quasi-experiments involve non-randomized comparative studies (e.g., pre-post comparisons)
    • Naturalistic studies investigate research questions without changing ongoing care practices

    Observational Studies of Psychological Treatments

    • Observational studies contribute alongside RCTs, especially with large sample sizes to observe small differences in treatment efficacy
    • Understanding user experience and relationships with treatment are crucial
    • Observational studies can explore various facets of treatment relationship, context, and key aspects of the treatment.

    Big Data

    • Routine data (national monitoring, NHS Digital, case notes) are increasingly used
    • Analyses use these data to rapidly perform large-scale studies.
    • Health informatics (using IT) improve data analysis in healthcare settings

    Implementation Gap

    • Widespread failure to translate research into practice, particularly in low-income countries and across healthcare settings is cited as a critical failing across most services.
    • Obstacles such as organizational and attitudinal factors hinder the adoption of effective interventions in clinical practice.
