t An online version of a Picture Story Exercise
(PSE) was administered to 180 participants to assess
implicit motives for achievement, affiliation, and power.
First, data were analyzed with respect to different aspects
of participant behavior (dropout, writing time, story length,
setting). Second, online data were compared with data
collected in the laboratory (n = 93). Results regarding
motive density, internal consistency, picture profiles, and
position effects were comparable among samples and
consistent with previous research (Pang and Schultheiss in
J Person Assess 85:280–294, 2005; Schultheiss and Brunstein
in J Person Assess 77: 71–86, 2001). In addition,
online participants completed self-report measures assessing
explicit motives and the Big Five personality factors.
Explicit motives showed no substantial overlap with PSE
motive scores, replicating previous research. Personality
factors revealed gender differences in correlates: men with
a high implicit power motive reported less agreeableness
and conscientiousness. Results suggest that administering
the PSE online yields reliable and valid data.
