Study Notes

Session 4: 4th Oct - pt1

Measurement Instruments: The session covered choosing measures for mental health research, outcome measurement domains. The reading list included PSBS0002: Core Principles of Mental Health Research from University College London.
Class Prep: Students were assigned readings on new trends in assessing mental health interventions, clinician confidence in using outcome measures across cultures, and overcoming barriers to recruiting ethnic minorities in mental health research. They also needed to review outcome measures for adult psychiatry, a catalogue of mental health measures, quality criteria for health status questionnaires, and strategies for making mental health research more inclusive.

What Do We Measure in Mental Health?

Objectives: The session aimed to introduce key domains of mental health measurement and familiarize participants with the strengths and limitations of various measures.
Selecting a Measure: The process involves formulating a clear research question, identifying relevant concepts, and selecting or developing appropriate measures for those concepts.

Which Contexts are Scales Used?

Research Studies: Scales are used to describe participants, assess intervention outcomes, and measure potential contributing factors.
Clinical Practice: Scales are used to track individual progress, assess needs, and evaluate services.

Types of Measures Used in Diagnosis

Semi-structured Interviews: Allow in-depth exploration of symptoms and provide a narrative account from participants; gold standard but expensive and time-consuming.
Structured Interviews: Often rely on self-reports or lay interviewers; useful because less training/time intensive.
Symptom Measures: Include overall screening measures (e.g., GHQ), measures covering a range of psychiatric symptoms (e.g., BPRS), and those specific to certain disorders (e.g., BDI).
Psychological Measures: Many assess personality traits, cognitive style, and other characteristics relevant to mental health problems.

Social Functioning: Involves daily living activities and social roles, from personal care to work. Disability is limitations on activities due to physical impairments.
Scales: Social Functioning Questionnaires and Life Skills profiles are often used.

Quality of Life

Objective Measures: Used in health economic analysis (e.g., EQ-5D), assess aspects like social functioning, pain, and anxiety.
Subjective Measures: Assess individual satisfaction with various aspects of life (e.g., MANSA questionnaire).

Outcomes that Service Users Value

Patient-Rated Outcome Measures (PROMS): These measures can capture the patient experience of mental health recovery.
Well-being: Scales like the Warwick-Edinburgh Wellbeing Scale measure positive aspects of how people feel.
Social Relations: Includes measures of social network size, supportive relationships, loneliness, and social capital.

Defining Data – Applied Statistics

Epidemiology and Medical Statistics: Exposure/independent variable, outcome/dependent variable, explanatory/predictor variables, response variables.

Statistical Inference and Samples

Statistical Inference: Using sample data to make inferences about a population.
Sampling and Populations: Distincting between a sample and a population and considerations for sample variability.

Type of Data

Variables and Categorical Variables: Identifying different types of data such as numerical or categorical as well as rates.

Summary

Different kinds of outcome measures (numerical, binary) depending on the nature of outcome/variable being studied.

Measurement Instruments (Notes)

Objectives: Review core principles of selecting measures, focusing on practical and psychometric aspects; apply these in questionnaire design and outline a plan for testing psychometric properties; evaluate challenges in conducting mental health research considering outcome measurement in various cultures.
Prep Group Task: Design a randomized controlled trial to evaluate a new group CBT for schizophrenia symptoms, using several outcome measures such as PANSS, PSYRATS, and Psychosis Screening Questionnaire. Compare the tools and choose the best for the trial.

Will the Questionnaire Pick Up Changes?

Responsiveness: Evaluate if the questionnaire detects changes over time and between groups; important from stakeholder perspectives.
Precision: Evaluate if the questionnaire provides a useful range of scores; addresses issues such as floor and ceiling.
Appropriateness: Assess whether the questionnaire is suitable for the intended study population and study question.

Questionnaire Feasibility?

Feasibility: Evaluate factors such as time constraints, tool complexity, and access to training and resources when evaluating tool use in practice.
Acceptability: Determines how appropriate the instrument is for a population based on elements such as language, stigma, and tone.

Cross-cultural Validity

Cross-cultural validity: Explore if instruments work similarly across different cultures and considering issues such as translation and validation.

Processes to ensure Validity

Translation/back translation to ensures meaning equivalence between languages
Qualitative investigation on how cultural factors may affect the outcome variable, and the different levels of the instrument.
Piloting the revised/translated tool across a diverse population.
