Study Notes
Core Principles in Mental Health Research
- Measuring accurately is crucial in mental health research
- Questionnaires and rating scales are common measurement tools
- Reliability and validity are key properties for assessing these tools
- Important to ensure the measures consistently capture the same thing
- Understand how to accurately measure symptoms and functioning
Psychometric Properties of Measures
- Reliability: Measurements are consistent and replicable
- Validity: Measures what it's intended to measure
- Feasibility and Acceptability: Is the measure practical and not burdensome?
- Sensitivity to Change/Responsiveness: Does the measure detect important changes adequately?
- Appropriate Scaling: Avoids floor or ceiling effects (extreme low/high scores)
Reliability
- Inter-rater reliability: Agreement between multiple raters/observers
- Test-retest reliability: Consistency of results over time
- Internal consistency: Items on a scale measure the same underlying construct. Cronbach's alpha is a common measure of internal consistency.
- Parallel forms reliability: Agreement between results using different versions of a measure.
Validity
- Internal Validity: Ensuring observed effects are due to the manipulated variable, not confounding factors. Techniques for improvement include controlling extraneous variables, using standardized instructions, and counterbalancing.
- Face Validity: The measure appears to measure what it intends to.
- Content Validity: The measure represents all aspects of the relevant domain.
- Criterion Validity: Accuracy based on correlation with a known standard (concurrent and predictive).
- Construct Validity: Examining the meaning and significance of results. (convergent and divergent).
Additional Considerations
- Cultural Considerations: Instruments need validation in diverse cultures
- Measurement Issues: Poor rater training or fluctuating conditions might affect instrument's reliability.
- Clinical Significance: Measures should be able to detect and capture clinically-important changes.
