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.
