Purpose
To assess participants’ daily affect over a period of several (6 or 14) days.
Description
On each evening during the interview period, interviewers asked participants to rate, using a 5-point scale, the extent to which a series of mood adjectives described how they had been feeling since they got up that morning. The interview affect questionnaire is included on the second page of the PCS2 interview form and on the last page of the PMBC and PCS3 interview forms.
Scaling
PCS2: 1 = haven’t felt that way at all since getting up; 5 = felt that way a lot since getting up*
PMBC, PCS3: 0 = haven’t felt that way at all today; 4 = felt that way a lot today
*To facilitate data aggregation, PCS2 item scores have been converted to a 0 to 4 scale.
Number of Items
PCS2: 25
PMBC, PCS3: 14
Sample Items
“Happy”, “tired”, “calm”, “sad”, “full of pep”
Psychometrics
PCS2
The internal-reliabilities the multiple assessments range between 0.89 and 0.93 for state Positive Affect scores and between 0.87 and 0.92 for state Negative Affect scores (). Validity of the trait Positive Affect measure (i.e., average across days) is demonstrated by a correlation of .49 (p<.001) with a self-report questionnaire assessment asking participants to rate their “usual” levels of positive mood ().
PMBC
The internal reliabilities of the multiple assessments ranged from 0.82 to 0.90 for state Positive Affect scores and 0.83 to 0.90 for state Negative Affect scores. ()
Variables
State Affect
The 7 individual state affect scale scores were created for each interview day by computing a mean score across the items comprising each scale (see Table 1, top panel). Composite state Positive Affect and Negative Affect variables were created by taking the mean of the relevant individual scales (see Table 1, bottom panel).
Trait Affect
Trait affect variables were created for the entire interview period by taking the mean across interview days of each of the 15 daily affect scores listed in Table 1.
