What are some feasibility issues with research?
-Scope of study -Time required -Fiscal costs -Ethical considerations -Cooperation required from others -Obtaining advance authorization
Variables
Broader concepts that vary (include more than one attribute or level of a concept) and that researchers investigate, e.g. age, gender, level of self-esteem, number of abusive incidents, etc.
Variable
A concept being investigated that is characterized by different attributes.
Validity
Are you measuring what you are supposed to be measuring?
Uncritical documentation
Assuming that because something is described in the literature it must be true; literature is cited, but no information is given about how the cited author arrived at a conclusion
TROUT
Tentative- Everything we know today, may change by tomorrow. Replication- All studies need to be replicated Observation- Knowledge is grounded in orderly and comprehensive observations Unbiased- Observations should be unbiased Transparent- All details are openly specified for review and evaluation
Triangulation
The use of more than one imperfect data collection alternative in which each option is vulnerable to different potential sources of error.
Three main threats to culturally competent measurement include:
- The use of interviewers whose personal characteristics or interviewing styles offend or intimidate minority respondents or make them reluctant to divulge relevant and valid information 2. The use of language that minority respondents do not understand, and 3. Cultural bias
Three Ethical Controversies
Observing Human Obedience Trouble in the Tearoom Social Worker Submits Bogus Article to Test Journal Bias
Three Advanced Mixed Methods Designs
=Intervention Mixed Methods Design =Social Justice Mixed Methods design =Multiphase Mixed Methods design
Theoretical sampling
A sampling method associated with the grounded theory paradigm of qualitative research, in which new cases are selected that seem to be similar to those that generated previously detected concepts and hypotheses, but once the researcher perceives that no new insights are being generated from observing similar cases, a different type of case is selected, and the same process is repeated until the observation of different types of cases seems to be generating no new insights.
The Scientific Method
-All knowledge is provisional and subject to refutation (everything is open to question) -Knowledge is based on observations that are: —Orderly and comprehensive (avoidance of overgeneralization) —As objective as possible —Replicated in different studies
Test-retest reliability
A method for assessing a measure’s consistency or stability.
Systematic sampling
An efficient alternative to random sampling, in which every kth element in the sampling frame list-after a random start-is chosen for inclusion in the sample.
Systematic review
reports comprehensive searches for published and unpublished studies that address a research question
Systematic Error
When the information we collect consistently reflects a false picture -Biases: The most common way our measures systematically measure something other than what we think they do is when biases are involved, e.g.: Acquiescent response set Social desirability bias
systematic error
A measurement error that occurs when the information we collect consistently reflects a false picture of the concept we seek to measure.
Study population
The aggregation of elements from which the sample is actually selected.
Straw person argument
illogical reasoning distorting an argument in order to attack it
Stratification
The grouping of units masking up a population into homogeneous groups (or strata) before sampling.
Steps to improve cultural competence
Cultural immersion: cultural and scientific literature; cultural events, travel, etc. Participant observation (Chap 18) Advice from colleagues who are members of the culture of interest Input from community members/leaders Focus groups
Steps in Evidence-Based Practice
Step 1: Formulate a Question to Answer Practice Needs Step 2: Search for the Evidence Step 3: Critically Appraise the Relevant Studies You Find Step 4: Determine Which Evidence-Based Intervention Is Most Appropriate for Your Particular Client(s) Step 5: Apply the Evidence-Based Intervention Step 6: Evaluation and Feedback
Spurious relationship
A relationship between two variables that are no longer related when a third variable is controlled.
sociological propaganda:
the penetration of an ideology by means of its sociological context via economic, political, and sociological structures
Social Justice Mixed Methods design
Methods based on a social justice theory and aimed at yielding a call for action to improve the plight of vulnerable, marginalized or oppressed groups
Social desirability bias
The tendency of people to say or do things that will make them or their reference group look good.
Social constructivism
A paradigm that emphasizes multiple subjective realities and the difficulty of being objective.
Snowball sampling
A nonprobability sampling method used when the members of a special population are difficult to locate. Each selected member of the target population whom one is able to locate is asked to provide the information needed to locate other members of that population that they happen to know.
Simple random sampling
Using a table of random numbers to select sampling units after assigning a single number to each element in the sampling frame list.
self-reports
A source of data that can be used when operationally defining variables according to what people say about their own thoughts, views, or behaviors.
Sampling unit
An element or set of elements considered for selection in some stage of sampling.
Sampling ratio
The proportion of elements in the population that are selected in a systematic sample.
Sampling interval
The standard distance between elements selected in systematic sampling.
Sampling frame
The list or quasi-list of elements from which a sample is selected.
Sampling error
The difference between the true population parameter and the estimated population parameter.
Research Purposes
-Exploration -Description -Explanation -Evaluation -Constructing Measurement Instruments -Multiple Purposes -Explaining and Predicting
Relying on testimonials
Claiming that a method is effective based on one’s own experiences
Relying on case examples
Drawing conclusions about many clients based on one or a few unrepresentative individuals
Reliability
-A particular measurement technique, when applied repeatedly to the same object, would yield the same result each time -The more reliable the measure, the less random error
Relationships between variables can be
positive, negative, or curvilinear
Relationship
Variables changing together in a consistent, predictable fashion.
Relationship
Variables that change together in a consistent, predictable fashion, e.g., height and weight
Reasons for Using Mixed Methods
-Extend main findings -Generate research questions or techniques -Corroborate findings
Reasons for Studying Research
To increase your practice effectiveness by critically appraising research studies that can inform practice decisions (Publication does not guarantee quality) The NASW Code of Ethics requires research utilization Compassion for clients?
Ratio level of measurement
A level of measurement that describes variables (such as age or number of children) whose attributes have all the qualities of interval measures and are also based on a true zero point.
Random selection
A sampling method in which each element has an equal chance of selection independent of any other event in the selection process.
Random sampling
A precise, scientific procedure for selecting research population elements for a sample that guarantees an equal probability of selection of each element when substantial samples are selected from large populations.
Random Error
Random errors have no consistent pattern of effects. They do not bias the measures. Examples: -Cumbersome, complex, boring measurement procedures -Measure uses professional jargon which respondents are not familiar with
Random error
A measurement error that has no consistent pattern of effects.
Quota sampling
A type of non probability sampling in which units are selected into the sample on the basis of pre-specified characteristics so that the total sample will have the same distribution of characteristics as are assumed to exist in the population being studied.
Questions that address Social Validity concerns
1) Are the goals important and relevant to desired change? 2) Are methods acceptable or too costly? 3) Are clients happy with expected or unexpected outcome?
Quantitative research methods
Research methods that seek to produce precise and generalizable findings. Studies using quantitative methods typically attempt to formulate all or most of their research procedures in advance and then try to adhere precisely to those procedures with maximum objectivity as data are collected.
Quantitative Methods Emphasize:
-Precision -Generalizability -Testing hypotheses
Quantitative Emphases
-Deductive -Larger samples -Objectivity -Numbers/statistics -Less contextual detail -Close-ended questions -Less time-consuming -Easier to replicate
Quantitative Collection
Office, agency, mail, or internet data collection setting
Qualitative research methods
Research methods that are more flexible than quantitative methods, that allow research procedures to evolve as more observations are gathered, and that typically permit the use of subjectivity to generate deeper understandings of the meanings of human experiences.
Qualitative Methods Emphasize:
-Deeper understandings -Describing contexts -Generating hypotheses -Discovery
Qualitative Emphases
-Inductive -Smaller samples -Subjectivity -Words/patterns -Rich descriptions -Open-ended questions -More time-consuming -Harder to replicate
Qualitative Collection
Data collected in natural environment of research participants
Quackery
Promotion of something known to be false or untested.
Purposive sampling
Selecting a sample based on your own judgement about which units are most representative or useful.
