     Evidence from many species demonstrates that the quality of the infant-mother relationship is crucial for understanding offspring development. The Attachment Q-sort is a validated metric for assessing the quality of this relationship, and has been adapted for use with captive Japanese monkeys and free-ranging rhesus monkeys (AQS-RM). We modified the AQS-RM for use with captive rhesus monkeys (AQS-CRM), and correlated this qualitative measure of infant attachment security with discrete behaviors of the mother-infant pairs. We also assessed whether the AQS-CRM scores differed among 10 maternally abused and 10 non-abused infants. Focal observations were collected across the first six months of life, and two observers coded eighty 30-min videotapes to calculate AQS-CRM scores at months 3 and 6. Pearson correlations and independent t-tests were applied with an alpha level of 0.05. AQS-CRM scores were significantly correlated with infant tantrums [r=-0.47], infant contact breaks from mother [r=0.55], mother-infant contact duration [r=0.54], and maternal rejections [r=-0.69]. At month 6, abused infants had significantly lower attachment scores [M=0.17] than non-abused infants [M=0.46]. These results indicate that the AQS-CRM provides a valid measure of attachment security in captive rhesus macaque infants. This measure is also sensitive enough to detect differences in infant-mother security between abused and non-abused infants, and may be useful for predicting developmental outcomes.
