The purpose of this study was to examine the effects of the Velten (1968) Mood Induction Procedure (VMIP) on psychological symptomology. Velten created a series of 60 statements designed to produce a particular mood: elated, depressed, or neutral. The VMIP came out of the cognitive movement, has undergone permutations over time, and other MIPs have been developed. Criticisms of the MIPs are discussed. The VMIP is feasible as a therapeutic tool due to flexibility and ease of use; In this study, the VMIP was utilized to induce an elated, depressed, or neutral mood. Hypotheses included: for elated condition (EC), report of symptoms would decrease; for depressed condition (DC), report of symptoms would increase; for the neutral condition (NC), there would be no change, and the DC would show a greater change than the EC, and both would show greater change than the NC. A total of 314 participants were given three measures in a pretest/posttest design: the Multiple Affect Adjective Checklist-Revised (MAACL-R), the Symptom Checklist-90-Revised (SCL-90-R), and 10 frequency questions (FQs). The VMIP was administered as the independent variable; The FQs were included to detect participant bias. Differences were found using ANOVA. The MAACL-R was used as a manipulation check for the VMIP. For the EC, mood changed in the expected direction, significantly for anxiety, depression, and positive affect. For the DC, mood changed significantly in the expected direction for all subscales. For the NC, mood changed significantly in a mixed way. The SCL-90-R was used to test for differences in the report of psychological symptomology. The EC changed significantly in the expected direction for all scales. The DC changed significantly in the expected direction for some subscales. The NC changed significantly in the same direction as the EC for all scales. A visual examination of the means showed that the DC created a greater mood change than the EC or NC. The EC created a greater mood change in the area of positive affect than the NC. The utility of using the VMIP as a therapeutic tool is discussed.
