Notes. Independent t tests were conducted to compare younger and older adults on these variables, and Pearson chi-square analyses were used when variables were categorical (e.g., frequencies of relationship status, income level). For the “In a relationship or married variable”: those who were not in a relationship or married were either single, widowed, or divorced. d = Cohen’s standard effect size; MMSE = Mini-Mental State Examination; SD = standard deviation.
