Subjective measures are used to assess mood, feelings, emotions, or other individualized responses to stimuli. CReSS Lab provides a full-featured questionnaire creation and administration function that gives you full control over the subjective instrument you want to create. Using a variety of different question types, you are able to create scales that assess nearly any subjective response. The data from subjectives are collected in simple flat files that can easily be imported into your favorite statistics package. You also have the option of generating printed reports (if your system is connected to a printer).

Creating and editing questionnaires is easy with CReSS Lab. The information you enter is stored on the PC in Test Configuration Files that can be moved from machine to machine. The links below provide screen shots for some of the common tasks used to create questionnaires:

• Creating a new questionnaire
• Adding a True/False element
• Adding a 5-Point Scale element
• Adding a 7-Point Scale element
• Adding a 7-Point Anchored Scale element
• Adding a Visual Analog Scale (VAS) element
• Adding an N-Point Scale element

Once created, the questionnaire becomes one of potentially many instruments you can administer in your research. The links below show several of the common tasks used to administer questionnaires:

• Selecting the Battery to administer
• Logging the Test Administrator and Volunteer IDs
• A True/False question
• A 5-Point Scale question
• A 7-Point Scale question
• A 7-Point Anchored Scale question
• A Visual Analog Scale as it appears
• An N-Point Scale question
• The "completion screen" shown after the final question

Smoking topography refers to the measures that assess puffing behavior. This includes number of puffs, puff volume, puff duration, inter-puff interval, and peak flow. You may want to measure smoking topography in order to quantify compensatory behavior. In addition, CReSS Lab provides a controlled-smoking mode that can be used to ensure each study participant receives the same exposure to the smoked product. As with the features discussed above, measured topography data are stored in flat files on the system and you have the option of generating printed reports.

CReSS Lab supports several different smoking topography modes. From ad-lib smoking to calibration, you have a complete set of tools for assessing puffing behavior. The links below provide screen shots for the different modes:

• Ad-Lib smoking
• Defining controlled (or directed) smoking profile
• Running controlled smoking
• Calibration of the smoking equipment

Performance tasks allow you to assess changes in physical coordination or cognitive power. CReSS Lab provides a pattern-matching task as well as one that measures changes in time perception. As with the features discussed above, measured performance data are stored in flat files on the system and you have the option of generating printed reports.

CReSS Lab supports a set of fully-configurable performance tasks that are easily administered to your study participants. The links below provide screen shots for the different modes:

• Creating a Digit Symbol Substitution Task (DSST)
• Running a DSST
• Creating a Time Estimation Task
• Running a Time Estimation Task

Physiological conditions are measured using one of the supported third-party vital signs monitors and a data cable from Plowshare Technologies. CReSS Lab accepts vital signs data via the PC serial port. It time/date tags the readings and stores them in flat files on the system with other measures. This gives you a time-ordered set of measures that are easily correlated with other recorded data. CReSS Lab collects heart rate, oximetry, skin temperature, and blood pressure.

CReSS Lab supports the following third-party physio monitoring devices:

• Criticare 507E Scholar II or Scholar III, available from Criticare
• Datascope Passport, available from Datascope
