The Massie-Campbell Attachment During Stress Scale (ADS, Massie & Campbell, 1983) is an observation guide of the interactions between mothers (or caretakers) and children from 6 to 18 months. This study sought the construct validity (convergent and discriminant) of ADS, as well as its criterion validity (sensitivity, specificity, and predictive values). To that end, child attachment was measured in a group of 32 children aged 8 to 10 months from Lima, Peru using ADS and Attachment Q-set 3.0 (AQS, Waters, 1995). Maternal sensitivity was assessed as well. It was found that ADS attachment classifications were related with AQS attachment security continuous scores (r = .41, p = .02) and with its dichotomous classifications [secure vs. insecure; χ2 (1, N = 32) = 4.69, p = 0.03, d = 0.83]. Additionally, no significant differences between the ADS’s maternal sensitivity of mothers with children classified as secure and mothers with children classified as insecure were found. Since ADS´s sensitivity did not reach satisfactory levels (33.3 %, 95 % CI = [15.48, 56.90]), a cut-off point of 5 secure behaviors was used, which improved its sensitivity (47.6 %, 95 % CI = [26.4; 69.7]) while maintaining satisfactory levels of specificity (90.9 %, 95 % CI = [57.1; 99.5]). The instrument shows adequate convergent validity but lacks evidence of discriminant validity. Further exploration of ADS’s sensitivity, specificity, and predictive values is recommended in order to obtain a cut-off point with greater validity, given that the instrument is considered a screening test.
