  4. 4. Respondents were being asked whether they will agree or disagree High scores are given to an agreement with positively worded items and disagreement with negatively worded items. This scale is also called summated rating scales
  5. 5. Semantic Differential Scales  The respondents will be ask to rate a concept on a series of bipolar adjectives.  easy and flexible to construct  concept can be anything like a person, situation, abstract idea, controversial issue, and others.  It can be presented as a word, phrase, or even as visual material.
  6. 6.  Several concepts can also be included in the semantic differential scale.  Two considerations that the researchers used as a guide in selecting bipolar scale.  Three independent dimensions:  Evaluation  Potency  Activity
  7. 7. The evaluative ones such as effective/ineffective, valuable/worthless, good/bad, and others were the most important group. The potency adjectives includes strong/weak and large/small. The examples of activity adjectives are active/passive and fast/slow.
  8. 8. Cognitive and Neuropsychological Tests  The study participant’s cognitive skills is also assessed by the researchers.  There are several types of cognitive tests.  Intelligence test - an example of cognitive tests - It evaluates a person’s global ability to perceive relationships, solve problems and aptitude test - measures a person’s potential for achievement  Neuropsychologic functioning among people with potential- cognitive impairments. E.g Mini- Mental Status Examination (MMSE)

It is also difficult and time.  It cannot be incorporated into mailed or Internet questionnaires or administered in telephone interviews.
  10. 10. Vignettes  Brief case reports or descriptions of events to which respondents are asked to react.  The descriptions can be either fictitious or based on fact which are structured to elicit information about respondents.  Usually written in narrative descriptions but researchers also use videotaped vignettes.  Economical means of eliciting information about how people might behave in situations that would be difficult to observe in daily life.
  11. 11. Vignettes can be incorporated in a questionnaire which makes it an inexpansive data collection. The main problem of vignette is the validity of responses. Potential biases should be taken into account in interpreting results.
