Abstract Objective Based on past research demonstrating increased worry among the oldest old compared to younger older adults, this study tested an existing cognitive model of worry to determine whether differences in executive functioning during aging contribute to increased worry among the oldest old. Method 97 community-dwelling older adults (M age = 74.49; range = 60–89 years) completed self-report questionnaires including the Penn State Worry Questionnaire, Geriatric Anxiety Scale, and Cognitive Problems and Strategies Assessment, and were individually evaluated with neurocognitive measures including the RBANS, DKEFS Color-Word Interference Test, and Modified Wisconsin Card Sorting Test. Results Two-way ANOVAs revealed no significant differences in worry based on age group (i.e., 60s, 70s, and 80s; F[2, 85] = 1.31, p = 0.28) or gender (F[1, 85] = 3.22, p = 0.08). Further, response inhibition and problem-solving did not predict anxiety or worry severity in multiple regression analyses. Lower education was the only consistent predictor of both anxiety and worry when accounting for cognitive performance, age, and gender. However, subjective cognitive functioning also predicted worry among older adults, independent of objective performance. Conclusion(s) No age differences in worry or anxiety severity were found. Also, no evidence was found to support age-differences in executive functioning as a contributor to worry presentation in late life. The cognitive model of worry may only be applicable to pathological worry or executive decline among the sample was not pronounced enough to impact anxiety. Overall, this study demonstrates that the cognitive model of worry is not supported in healthy, community-dwelling older adults. However, limitations included limited demographic diversity, small sample size, and limited measurement of executive functioning.
