Study Notes
Randomised Controlled Trials (RCTs)
- RCTs are the gold standard for research, originally developed for drug trials and now extended to other interventions.
- RCTs aim to provide fair comparisons of interventions, unaffected by initial differences between groups by using objective measures, independent observers, and analysts blind to participant group assignments.
- RCTs evaluate whether innovations genuinely work.
- A theoretical framework is developed to guide intervention design, and evidence is gathered to adapt or incorporate elements of existing interventions.
Developing and Testing Interventions Using RCTs
- Intervention components are modeled and tested for feasibility and acceptability by the researchers.
- Pilot studies assess the intervention and trial procedures.
- A definitive RCT follows, followed by implementation studies.
- Intervention's components are reviewed throughout the development process to ensure they remain central.
Framework for Complex Interventions
- Core elements are revisited continuously throughout the intervention development process.
- Limitations of RCTs include the lengthy process, potential influence of contextual factors (e.g., participant characteristics or organizational culture), difficulty applying them to whole services/areas, and lack of emphasis on service user experience.
- Cost-effectiveness and cost-benefit analysis are increasingly considered.
Alternative Approaches
- Naturalistic studies: Investigate research questions without altering existing care practices, exemplified by cohort studies exploring rehabilitation services for psychosis.
- Quasi-experiments: Non-randomized comparative studies, often using pre-post comparisons or service/area comparisons (e.g., evaluating the TIPS intervention against usual care), have improved with modern statistics and routine data.
- "Big data": Utilize national monitoring data (e.g., NHS digital data), anonymized case notes (e.g., CRIS), and national/local registries (e.g., Swedish cohorts) for efficiency and representativeness.
- Health informatics: The science of using information technology to improve health, supporting innovative approaches to routine data use.
Qualitative Research
- Qualitative research offers insights into service user perspectives, neglected in RCTs.
- Qualitative research uses methods like interviews, focus groups, and diaries to explore text and experiences, informing intervention development and understanding intervention success/failure.
- Qualitative data can be incorporated within mixed-methods designs to enhance evaluations of complex interventions.
Developing Interventions
- Intervention development is driven by a defined clinical problem, unmet need, and target population.
- Available evidence for similar interventions and views of relevant stakeholders (increasingly emphasizing co-production) inform the design.
- A program theory, explaining the causal link to desired change, is crucial.
Program Theories
- Interventions should be theory-driven, potentially incorporating psychological or sociological frameworks (e.g., Theory of Planned Behavior), which are refined throughout.
Theories of Behavior Change
- Interventions frequently use pre-existing behavior change theories, often involving health psychologists.
- A study-specific theory of change (logic model) is crucial to intervention design.
RCTs in Mental Health Research
- Drugs: RCTs remain the primary method to evaluate new drug treatments for adherence and treatment effects. Challenges include issues of partial disclosure, short follow-up times, potentially biased control groups and publication bias. Trials are highly regulated and monitored as CTIMPs (Clinical Trials of Medicinal Products).
- Psychological Treatments: RCTs are the standard for CBT and third-wave therapies. Manualizing interventions, trained therapists, monitoring of intervention provision, and cost-effectiveness assessments are critical.
- Complex Psychosocial Interventions: RCTs evaluating interventions with components like crisis care and supported employment face challenges with quality, replication, participant/organizational/cultural context considerations, and implementation.
Cluster Randomized Trials
- Randomizing at a higher level (e.g., staff or teams) is useful when individual randomization is difficult (e.g., organizational interventions).
- Challenges include larger sample sizes and logistical complexity, particularly for pre-randomization assessments.
Observational Research
- Observational Studies (Drugs): Investigating associations between factors without manipulation, with advantages such as long-term follow-up of drug effects, treatment patterns, and unselected large samples. Observational studies can be helpful for studying differences between drugs in treatment outcomes.
- Observational Studies (Psychological): Investigating small differences in treatment outcomes, therapeutic relationships, and contexts with large samples. These studies are useful for understanding who benefits from particular treatments. Large observational studies are relevant to research on area-level public mental health interventions (e.g., stigma reduction campaigns).
Implementation Gap
- A significant gap exists between research findings and the application of effective interventions, especially in middle/low-income settings. Implementation delays, particularly regarding family interventions, are prevalent.
Implementation Science
- Aims to overcome obstacles to intervention uptake by considering organizational and attitudinal factors, and explore strategies to increase the translation of research into practice.
Other Key Points
- RCTs remain valuable but are challenging in assessing complex interventions.
- Careful consideration of when observational or other methods are more efficient and generalizable is critical.
- Qualitative research is increasingly used in mixed-methods designs, enhancing evaluations of complex psychosocial interventions.
- Qualitative research explores the perspectives of a range of stakeholders to understand what works, identify mechanisms of intervention success/failure and uncover practical constraints/enabling factors. Interventions should be grounded in realistic understandings of how they might be implemented.
