The field of psychology that examines the diverse properties of tests is referred to as psychometrics
Assessment principles
Reliability
Validity
Objectivity
Reliability
A test produces consistent outcomes in a particular individual when administered twice with a small time interval
Validity
The degree to which a particular method measures the psychological property it is intended to measure
Validity measures
Construct validity
Discriminant validity
Convergent validity
Cross-validity
Objectivity of research method
Independence of results from researcher's intentions and personality
Analysis of all data obtained, not merely those related to the research hypothesis
Verification of data by other methods
Equal procedures for all participants
Interview
1. Introduction
2. Main phase
3. Conclusional phase
Interview topics
Area of free facilitation (emotionally neutral)
Area of psychodynamic (emotionally significant, mostly traumatic)
Ensuring psychological comfort in interview
Well-prepared interview
Calm atmosphere and trust with interviewee
Encourage openness
Interview types
Unstructured
Semi-structured
Structured
Clinical interview
Identifies if an individual has personality traits associated with a particular mental disorder
Self-assessment scales
Questions or statements that allow participants to assess their personal states, experiences, beliefs, interests, convictions, attitudes, and other subjective factors
Test
Laboratory-based examination where individuals perform a task or demonstrate abilities
Questionnaire
Self-assessment form used for researching personal characteristics
Construct being studied (e.g. cognitive process, personality trait, state)
Measurement scales
Dichotomous scale
Likert scale
Dichotomous scale
Provides alternative response with two categories (e.g. yes/no)
Likert scale
Allows expressing degree of agreement/disagreement with a statement
Psychological questionnaires
Measuring current states
Measuring personality traits
Psychological assessment methods and measures employed in clinical research are essentially psychometric techniques
Psychological research norms are updated every 20-30 years due to dynamic cultural and environmental influences on the human psyche
Cognitive methods
Investigation of cognitive functions - attention, memory, thinking, and perception
Cognitive methods
Investigation of the cognitive functions - attention, memory, thinking, and perception
Cognitive methods
Serve to evaluate the characteristics of cognitive processes, including concentration and attention distribution, memory retention and reproduction, cognitive capacity (logic, speed, flexibility, criticality, etc.), and consistency of perception
Have high diagnostic value in assessment of the individual psyche and in relation to cognitive disorders accompanying various neuropsychiatric disorders
Constitute a large heterogeneous group of assessment tools that are highly effective for clinical and psychological screening needs
Chappuis Labyrinth
1. Subjects trace the exit path of a labyrinth from the centre to the exit without making contact with the walls
2. Score determined based on execution time, mistake rate, and touching limit lines
3. Specialist may assume primary attention characteristics (concentration, persistence, and switchability) have not been impacted pathologically
4. Unified coefficient of success calculated reflecting the ability to cope with the task
Luria Memory Test
1. A set of ten monosyllabic or two-syllable words read to a person
2. First part requires person to listen and repeat the words to assess auditory memorization rapidity
3. Second part requires person to reproduce the words an hour later to assess auditory memory stability and long-term memory capabilities
4. Results plotted on a graph depicting memory dynamics
Poor dynamic results in Luria Memory Test may indicate organic brain diseases or emotional problems, even schizophrenia
Insufficient sustained attention can produce fluctuations in Luria Memory Test results, indicating emotional passivity or lack of interest
Attention
A critical metric for assessing the properties of all cognitive processes
Mini-Mental Status Exam (MMSE)
1. Cognitive screening tool that provides a brief, objective measure of cognitive function
2. Tests orientation to time and place, attention/concentration, short-term memory (recall), language skills, visuospatial abilities - visual and spatial relationships between objects, ability to understand and follow instructions
3. Maximum score is 30, with 25 or higher classed as normal
A high MMSE score does not necessarily mean that you don't have cognitive impairment, and a low score does not necessarily mean that you have dementia
Verbal intelligence
Studied through verbal stimuli
Non-verbal intelligence
Studied through graphic visual stimuli
Raven's Progressive Matrices (RPM)
1. Consists of 60 picture-based problems, divided into five series (A, B, C, D, and E) with 12 problems each
2. Difficulty increases with each series
3. Assesses capability of logical and abstract thinking and the G factor (individual's ability to solve mathematical and logical problems, as well as their general educational capacity)
An extremely poor performance on the Raven test may indicate shortcomings in cognitive and intellectual development
Projective methods
Tests to examine unconscious emotional states, processes, and personality characteristics
Rorschach test
1. Participant provides subjective interpretation of inkblot pictures, including what they perceive, what it resembles, what it could represent, and what it brings to mind
2. Associations recorded with accuracy per research protocol, taking into account latency time
3. Examiner and participant discuss features of the inkblot that led to the response and what facilitated associations
Projective methods
Efficient in evaluating creativity, cognitive style, and personal unconscious aspects (e.g., needs, motives, emotions, and attitudes)
Divided into different groups according to their purpose, stimulus, and research goal (constructive, associative, complementary, expressive)
Anamnesis
Patient's history in relation to the development of the disease, using both the patient's self-report and the report of others
