This article explores the understudied yet prevalent phenomenon of on‐again/off‐again (on‐off) dating relationships. Study 1 (N= 445 U.S. college students) showed that almost two thirds of participants had experienced an on‐off relationship. Analyses of open‐ended responses about relationship experiences showed on‐off partners were less likely to report positives (e.g., love and understanding from partners) and more likely to report negatives (e.g., communication problems, uncertainty) than partners who had not broken up and renewed. Study 2 (N= 236), employing quantitative measures, substantiated these findings and further showed a greater number of renewals was associated with greater negatives and fewer positives. Results highlight the need for further investigation regarding on‐off relationships, and theories potentially useful in explaining these relationships are discussed.

Exploratory factor analysis is a popular statistical technique used in communication research.Although exploratory factor analysis (EFA) and principal components analysis (PCA) are different techniques, PCA is often employed incorrectly to reveal latent constructs (i.e., factors) of observed variables, which is the purpose of EFA. PCA is more appropriate for reducing measured variables into a smaller set of variables (i.e., components) by keeping as much variance as possible out of the total variance in the measured variables. Furthermore, the popular use of varimax rotation raises some concerns about the relationships among the factors that researchers claim to discover. This paper discusses the distinct purposes of PCA and EFA, using two data sets as examples to highlight the differences in results between these procedures, and also reviews the use of each technique in three major communication journals: Communication Monographs, Human Communication Research, and Communication Research.

The current study employed a confirmation perspective to examine the relationship between communication with significant others and individuals’ weight management. Confirmation was conceptualized as consisting of two components—acceptance and challenge. In Study 1, 413 participants (aged 18-66) completed a survey assessing their diet and exercise behaviors as well as interactions with a significant other about weight management. As predicted, the combination of acceptance and challenge from significant others was related to the highest levels of body self-esteem, eating and exercise self-efficacy, and healthy eating behaviors beyond the individual effects of acceptance and challenge. In Study 2, 161 participants (aged 18-62) rated the effectiveness of messages varying in acceptance and challenge. Messages higher in both acceptance and challenge were rated as more effective in motivating healthy behaviors than messages primarily higher in either acceptance or challenge or lower in both. Overall, both studies suggest the contribution of one component of confirmation was enhanced by the presence of the other component in predicting weight management attitudes and behaviors.

Although relational research predominantly conceptualizes romantic relationships as either together or apart, some relationships break up and renew (i.e., on-again/off-again relationships). Partners’ accounts of on-again/off-again relational experiences were qualitatively analyzed to explore both reasons for breakups and reasons for renewals. Themes were interpreted within an interdependence framework to explain why partners dissolved as well as renewed their relationships. The themes in combination suggest renewals occurred due to dissatisfying experiences with alternative relationship partners and an increase in outcomes (i.e., rewards minus costs) after breakups. Partners’ post-dissolution contact and their uncertainty about relational status may have further facilitated renewals. More generally, the themes suggest, for on-again/ off-again partners, breakups did not indicate the end of interdependence but rather a redefinition of the relationship.
