“…Comprehensive explanation in these studies can be summarized as follows: Mood is an emotional state that lasts for a long time, having indistinct objects (Clark & Watson, ; Guerrero, Andersen, & Trost, ); emotion is an intense feeling, having an object and shorter duration (Planalp ); and affect is an expressed emotion, having both positive and negative dimensions (Cohen‐Mansfield et al., ; Lawton et al., ; Lee, Algase, & McConnell, ; Lee, Boltz, Lee, & Algase, ; Lee et al., ; Magai et al., ). Although the meaning of the three words is different (Williams & Tappen, ), they were often used interchangeably (Beerens et al., ; Boersma, Van Weert, Lissenberg‐Witte, Van Meijel, & Droes, ; Kolanowski, Hoffman, & Hofer, ). In most studies, affect is described more comprehensively to encompass the other terms (Cohen‐Mansfield et al., ).…”
