*3.5. Effectiveness of Doll Therapy on Emotions*

Four studies [20,29,31,32] reported benefits in the use of dolls to provide emotional support. Three of those studies found statistically significant improvements regarding the emotional component of people with dementia. Shin [20] reported statistically significant differences in positive mood and found a significant diminishment in depression (*p* < 0.01). In this way, Moyle's work [29] had a positive effect on well-being (*p* < 0.05), and Balzotti's study [31] reported mood changes at the third week of treatment: IC del 95% (−1.09 a 0.20) and the presence of anger (CI: −0.51 a 0.51). It also found improvements in depression (Z = 2.02, *p* = 0.04) and apathy (Z = 2.01, *p* = 0.04).
