Care partners are often uncompensated and face multifaceted challenges that contribute to stress. The Care Partner Stress Scale (CPSS) was developed to assess caregiver stress across seven domains: cognition, behavior, function; unmet needs and emotional impact; work and financial strain; family and interpersonal conflict; and situational perception.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To evaluate psychometric properties of the CPSS in care partners of individuals with neurocognitive or neurodegenerative diseases of aging.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n The CPSS was completed by 168 (83.93% female, age\u2009=\u200961.98 years) care partners in the CAN-PROTECT online cohort. Participants completed measures of depression, anxiety, quality of life, function, loneliness, and life satisfaction and engagement. We assessed internal consistency, item-total correlations, convergent and discriminant validity, and floor\/ceiling effects.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The CPSS demonstrated excellent internal consistency (\u03b1\u2009=\u20090.95, 95% CI: 0.94\u20130.96), with item-total correlations >0.23. Higher CPSS scores were associated with greater depression (\n b<\/jats:italic>\n \u2009=\u20092.38, 95%CI [0.72, 4.03],\n p<\/jats:italic>\n \u2009=\u20090.005), anxiety (\n b<\/jats:italic>\n \u2009=\u20094.47, 95%CI [2.44, 6.50],\n p<\/jats:italic>\n \u2009<\u20090.001), and anxious distress (\n b<\/jats:italic>\n \u2009=\u20096.37, 95%CI [3.54, 9.21],\n p<\/jats:italic>\n \u2009<\u20090.001), as well as lower life satisfaction (\n b<\/jats:italic>\n \u2009=\u2009\u22123.42, 95%CI [\u22125.61, \u22121.23],\n p<\/jats:italic>\n \u2009=\u20090.002), poorer social relationships (\n b<\/jats:italic>\n \u2009=\u2009\u22122.31, 95%CI [\u22124.54, \u22120.09]\n p<\/jats:italic>\n \u2009=\u20090.042), greater loneliness (\n b<\/jats:italic>\n \u2009=\u20095.26, 95%CI [1.33, 9.19],\n p<\/jats:italic>\n \u2009=\u20090.009), and poorer life engagement (\n b<\/jats:italic>\n \u2009=\u20092.89, 95%CI [1.23, 4.65],\n p<\/jats:italic>\n \u2009=\u20090.001).
