A negative mood induction procedure with efficacy across repeated administrations in women

Although several experimental techniques are effective in inducing negative mood, none has established efficacy over repeated testing. The lack of mood induction tools validated across repeated administrations impedes study of emotional changes in the same individual over time. A brief, sad mood induction combining music and an autobiographical memory was administered to 17 women on 6 occasions (two 3-day sets over a 2-week period of time). Mood was measured before and after the induction procedure. Repeated measures ANOVAs showed that the induction produced a large increase in POMS depression (d = 1.48) that recurred consistently across all testing days. A brief negative mood induction combining music and autobiographical memory appears suitable for use in studies that involve repeated administrations.
