“…We assessed positive activation with six positive affect items from the Positive and Negative Affect Schedule (PANAS; "active," "interested," "excited," "strong," "inspired," and "alert"; Watson, Clark, & Tellegen, 1988), serenity with four items ("calm," "relaxed," "laid-back," and "placid") from a measure developed by Abele-Brehm and Brehm (1986), negative activation with six negative affect items from the PANAS ("distressed," "upset," "irritable," "nervous," "jittery," and "afraid"), and fatigue with four items from the Profiles of Mood Scales ("fatigued," "tired," "exhausted," "spent"; We assessed daily hassles during evenings and sleep duration as day-level control variables. We measured daily hassles in the bedtime survey with nine 5-point Likert items adapted from the measure developed by Bolger et al (2003;g. "Today I had an argument with my spouse").…”
