A qualitative analysis of tattooing in an inmate population

Purpose: The purpose of this investigation was to determine the quantitative effects of laughter on sleep patterns in a nursing home setting. The prediction was made that induced laughter would significantly improve sleep patterns in subjects over other treatment and conditions. Methods: Using a within-subjects design, three different conditions were manipulated for three consecutive periods of five days each. During the first five day period, the subjects were questioned about their sleep patterns and other related behavioral issues. This questioning continued with the addition of funny movies during the second consecutive five day period. The third five day period was conducted in the same manner as the second except that not-funny, interesting movies were shown. Findings: 1. The original hypothesis, that laughter induced through the funny movie treatment condition would significantly affect sleep patterns relative to the other treatment conditions, was not confirmed. 2. However, both the funny and not-funny conditions were significantly different from the no-movie treatment (p< .0001). 3. Likewise, self-esteem measured during the funny movie and not-funny treatments was significantly different from the no-treatment condition (p < .005).
