Identify how the concept was measured. Be specific by identifying the measurement tool. For example, if you are interested in measuring depression among postpartum women, the Edinburgh postnatal depression scale may have been used in a study as it is a commonly used instrument.

Data Collection Techniques in Nursing
One of the most important decisions that a researcher has to make is how data will be collected. The nurse who is implementing evidence-based practice also needs to consider how outcomes will be measured
Consider the following concepts frequently used in nursing research:

Caring
Quality of life (patient)
Nurses’ job satisfaction
Critical thinking
Empowerment
Stress

Once you have identified a published research study address the following:

Identify the concept (how is it defined).
Identify the type of research design and provide a copy of the article via a PDF file.
Identify how the concept was measured. Be specific by identifying the measurement tool. For example, if you are interested in measuring depression among postpartum women, the Edinburgh postnatal depression scale may have been used in a study as it is a commonly used instrument.
If a measurement tool was used to collect the data, briefly describe the instrument. (Example: The Finley Fall scale is a 10-item Likert scale with 2subscales). Also describe the validity and reliability of the tool. State if the validity and reliability is not described. If the measure is diagnostic test, describe the specificity and sensitivity.
