In this study, the authors examined relations between volunteer client adult attachment and both (a) memory for negative affect occurring within the first session of therapy and (b) mood awareness (mood labeling and mood monitoring). Participants were 80 volunteer clients (students with a personal issue who volunteered to participate in the research for credit) who participated in 2 counseling sessions with a counselor trainee. As hypothesized, higher levels of attachment anxiety were associated with (a) greater memory for negative affect and (b) more mood monitoring but, contrary to expectation, were not associated with mood labeling. Also contrary to expectation, attachment avoidance was not associated with a minimizing strategy with respect to memory for emotion or monitoring of mood, but it was negatively related to mood labeling. As hypothesized, some evidence emerged for an Attachment Anxiety× Avoidance interaction in predicting memory for negative affect. There were no significant Attachment Anxiety× Avoidance interactions in predicting mood labeling or mood monitoring.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
