This study investigates longitudinally predictors and outcomes of sliding (a desire to avoid clarifying the status of a romantic relationship; measured as relationship talk avoidance) among emerging adults (N = 244) in cyclical (ending and renewing a relationship) and noncyclical romantic relationships. Avoidance of relationship talk was positively associated with relationship uncertainty 7 weeks earlier and negatively related to dedication and satisfaction 7 weeks later, through decreased relationship maintenance (measured by constructive communication). We hypothesized that sliding would both predict and be predicted by lower dedication. Dedication did not predict later sliding for cyclical partners, but was associated with lower sliding for noncyclical partners, suggesting dedication may buffer the negative impact of uncertainty for noncycling partners.
