Competence I: Ch 3, 4, & 21 Flashcards
Research Questions
research questions are key elements in developing a topic area, and in essence are questions that explore the relations among or between constructs. Ex: Does the client’s level of dysfunction affect the working alliance formed in counseling?
Research Hypotheses
more specific in that it states the expected relationship between the constructs. Ex: More-dysfunctional clients will form poorer alliances in counseling than less-dysfunctional clients.
Descriptive Questions
ask what some phenomena or events are like. Developed by collecting inventories, surveys, or interviews to describe events.
Difference Questions
Ask if there are differences between groups of people, or even within individual participants. A comparison must be taking place in some form. Ex. Between group and within group designs
Relationship Questions
explore the degree to which two or more constructs are related or vary together. Use correlations or regression analyses.
Function of a testable research question/ hypothesis
- Asks a question about 2. the relationships between two or more constructs that can be 3. Measured in some way.
- The question should be worded clearly and unambiguously in question form
- the research question should inquire into a relationship between two or more constructs, asking whether construct A is related to construct B (mostly for difference or relationship questions, descriptive questions collect information or categorize information)
- Relationship is examined and also measured
- The question should be worded clearly and unambiguously in question form
Operational Definition
specifying the activities or operations necessary to measure a construct in a particular experiment. Provides a working definition of a phenomenon.
Uniformity Myth
We have oversimplified counseling to assume that psychotherapeutic treatments are standard (uniform) set of techniques, applied in a consistent (uniform) manner, by a standard (uniform) therapist, to a homogeneous (uniform) group of clients. Greatly hampered our progress in understanding counseling research, so encourage questions about best types of treatments for particular types of clients across various settings. Translates into a research design myth, that one type of research is better than all others when we should be asking, what is the best research design for this particular problem at this time.
MAXMINCON Principle
Researcher first tries to maximize the variance of the variable(s) pertaining to research question, second minimize the error variance of random variables, third control the variance of extraneous/ unwanted variables. Applies most directly to experimental research (between or within groups design) can also be applied to all research designs.
Internal Validity
internal validity of a study is the experimental control allowing researchers to make more inferences about causal relationships between variables. High in control use random selection of participants, random selection to treatments, manipulation of IV to allow researcher to make inferences about causality.
External Validity
generalizability of the results to applied settings
Experimental Field Studies
Moderate external validity and internal validity. (high and high in table) Characterized by investigations that manipulate IVs and are conducted in real life settings. Examine causality through random assignment of treatment and control of IVs. Moderately high in external validity. Can never exercise same control in field as in laboratory, only moderately high internal validity as well.
Experimental Laboratory Studies
low in external validity and high in internal validity. Characterized by manipulation of IVs and are conducted in laboratory settings. Low external because instead of using participants directly sampled from a population of interest experimenter sets up a situation to resemble a naturally occurring one. High in internal because experimenter randomly assign participants to treatments and manipulate one or more IV. Can make inferences about causality.
Descriptive Field Studies
High external validity, low internal validity. Are investigations that do not exercise experimental controls and are conducted in a real life setting. High external because sample can be taken directly from a population of interest. Low internal because variables are studied as they occur naturally rather than being manipulated.
Descriptive Laboratory Studies
Low in both internal and external validity. Investigations that do not exercise experimental controls (randomization or manipulation of IV) that are conducted in laboratory settings. Low in external because uses a setting that can only simulate real life. Low in internal validity because lacks experimental control in manipulation of an IV or randomization of participants. This study involves describing , identifying, and categorizing data and obtaining descriptive stats. Two reasons conduct this study: 1. Laboratory setting allows researcher some control over extraneous variables 2. It is impossible to study some phenomena in a field or real life setting.
