Affect Intensity Measure (AIM, Larsen)
PsychologyReliability: alpha 0.903 sample items
About this scale
A 40-item measure of affect intensity — the typical strength of emotional responses regardless of valence. People who score high feel both highs and lows more intensely.
Sample item(s)
“When I'm happy, I bubble over with energy”
“When I do feel anxiety, it is normally very strong”
“My emotions tend to be more intense than those of most people”
Reliability
Reported internal consistency: alpha 0.90. As a rule of thumb, Cronbach’s α ≥ .70 is considered acceptable, ≥ .80 good, and ≥ .90 excellent for established measures.
