The purpose of this study was to determine if the use of humorous video, especially humor that produces laughter, would prove effective and valuable in reducing the level and degree of anxiety among law enforcement officers. Prior studies have incorporated the use of humorous video to successfully reduce stress and anxiety levels among other populations. Seventy-nine officers from two law enforcement agencies participated in this study. The experimental participants were given a first-round of the State Trait Anxiety Inventory (STAI, Speilberger, Gorusch, Vagg, & Jacobs, 1983) then shown a short laughter-producing humorous video, after which a second round of the measurement was administered. A 30-day follow-up STAI Self-Evaluation Questionnaire was also administered. Officers from the control participant group followed the same procedures, but were shown a non-laughter producing video travelogue of the same duration. Analysis was conducted and significant reductions between STAI state scores before and after viewing the videos were determined and found to be similar for both groups. Thirty-day follow-up STAI state scores increased, indicating the effects of the video wore off for the experimental group; however, there was no effect on state scores for the control group. Thirty-day follow-up scores revealed no effect on trait for the experimental group; however, testing of the control group revealed a decrease in trait scores. Results suggest the travelogue video shown to the control group may not have been truly neutral and may have evoked a sense of escape and rest thereby contributing to measured lower levels of state anxiety. Additionally, it is suggested demand characteristics may have influenced participants and impacted subsequent results.
