How do you derive value expectancies in SPSS by multiplying each expectancy variable (e.g., It would help me cope with stress) by the corresponding value variable (e.g., How positive or negative would you feel about coping well with stress)?Note that the value variables (C1pre through C8pre) are coded from -1 (Very Negative) to 1 (Very Positive) so that the new variables you compute here can, in theory, range from -5 (Strongly Agree and Very Negative) to 5 (Strongly Agree and Very Positive)
