Neuroticism is a dimensional personality trait, not a relationship diagnosis and not a label for a “bad partner.” In the Big Five tradition, it describes relatively stable individual differences in the tendency to experience negative emotions, distress, threat sensitivity, worry, frustration, and emotional reactivity. The opposite pole is commonly called emotional stability; the BFI-2 uses the closely related domain label Negative Emotionality. For the core personality construct, see Neuroticism: What It Is in the Big Five Personality Model.
In romantic relationships, higher neuroticism is associated on average with lower relationship quality, but the association is moderate rather than deterministic. A 2025 meta-analysis of 148 published studies reported an aggregate correlation of r = −.238 between neuroticism and relationship quality, with broadly similar male and female actor and partner correlations (Esplin et al., 2025). That result means neuroticism is relevant to relationship functioning at the population level; it does not mean a person’s score predicts the quality, duration, or future of a particular relationship.
The most useful question is therefore not whether neuroticism is “good” or “bad” for love. It is how a broad personality disposition can become expressed through relationship-specific processes: how ambiguous partner behavior is interpreted, how strongly emotions change during conflict, how stress spills into the relationship, which conflict behaviors occur, how quickly partners recover, and how each person’s responses affect the other. Longitudinal dyadic research supports this process-focused view, while also showing that cognitive, emotional, and behavioral pathways do not all contribute equally (Kreuzer & Gollwitzer, 2022).
Neuroticism and romantic relationships: the short answer
People higher in neuroticism tend, on average, to report more relationship distress and lower relationship quality. Several mechanisms can contribute. They may react more strongly to negative events, remain distressed longer after a difficult interaction, interpret ambiguous relationship information more negatively, experience more worry about rejection or conflict, and enter recurring interpersonal loops in which interpretation, emotion, behavior, and partner response reinforce one another. These are statistical tendencies across groups, not universal features of every person high in neuroticism.
The relationship is also dyadic. One partner’s neuroticism can matter for that person’s own relationship experience, which researchers call an actor effect, and it can sometimes matter for the other partner’s experience, a partner effect. The evidence for actor effects is especially consistent. Partner effects are real in some studies and outcomes but less uniform, which is one reason a single personality score should never be treated as a compatibility verdict.
Romantic relationships can also feed back into personality-related processes. Relationship-specific interpretation biases can change over time, and those changes have been associated with changes in neuroticism. Daily affective coupling between partners has likewise been linked with later personality change in an older-couple sample. The evidence therefore supports a transactional picture in which personality shapes relationship experience while relationship experience can also become part of personality development (Finn et al., 2015; Mueller et al., 2021).
What neuroticism means in relationship research
Neuroticism is a broad trait dimension. It is wider than anxiety, wider than momentary negative affect, and wider than any single conflict style. A person can score relatively high in neuroticism while functioning well in relationships, and a person can score relatively low while having serious relationship difficulties for reasons unrelated to neuroticism. Trait scores describe tendencies across time and situations; they do not describe every state, every interaction, or every decision.
This distinction is particularly important in relationship discussions because everyday language often collapses multiple constructs into one. Neuroticism is not the same as being anxious during an argument, having an anxiety disorder, experiencing a depressive episode, feeling jealous, having an insecure attachment pattern, or being emotionally abusive. Those phenomena can correlate with one another, but each has its own definition and evidence base. Neuroticism is also distinct from negative affect, which may refer to a transient state or an affective tendency depending on the measure; see Neuroticism and Negative Affect: How the Constructs Overlap and Differ.
Measurement matters. Relationship studies have used different personality instruments, including NEO measures, Eysenck scales, Big Five inventories, and other validated questionnaires. A “high” raw score in one instrument is not automatically equivalent to a high score in another because item content, scoring direction, normative samples, and scale ranges differ. The relationship literature supports conclusions about the neuroticism construct; it does not create a universal cutoff above which relationships become unhealthy.
What the strongest evidence shows
A robust but moderate association with relationship quality
The clearest broad finding is an inverse association between neuroticism and relationship quality. The recent meta-analysis by Esplin and colleagues integrated 148 published studies and found an aggregate r of −.238 (Esplin et al., 2025). An effect of this size is meaningful across large populations while still leaving substantial room for other influences: partner behavior, attachment processes, stress, communication, life circumstances, values, health, economic pressure, relationship history, and many other individual and dyadic factors.
Relationship quality is an umbrella outcome, not a synonym for one specific questionnaire or one momentary feeling. Individual studies may operationalize satisfaction, adjustment, intimacy, conflict, or global relationship evaluation differently. That is why the meta-analytic association is best understood as a broad summary rather than a statement that every subdomain of romantic life changes by the same amount.
Actor effects are usually more consistent than partner effects
Dyadic studies separate a person’s own trait from the partner’s trait. In a nine-year longitudinal analysis of 972 people in heterosexual couples, lower neuroticism and higher conscientiousness were associated with long-term relationship satisfaction through actor effects, while partner effects were not significant in that dataset (Bach et al., 2025). Other studies do detect partner effects, and the 2025 meta-analysis found similar differentiated actor and partner correlations across men and women. The overall record therefore does not support a simple claim that a partner’s neuroticism always harms the other person in the same way.
The actor–partner distinction also clarifies why two people can live through the same interaction and evaluate it differently. Neuroticism can influence the perceiver’s emotional and cognitive processing, so part of the statistical relationship with satisfaction may occur within the person who holds the trait. At the same time, observable behaviors during conflict can affect the partner directly. Both pathways can coexist.
Longitudinal evidence is informative but does not reduce the story to one-way causation
Longitudinal studies help establish temporal ordering, yet they still do not automatically prove causality. In a classic four-year study of 60 newlywed couples, neuroticism was associated with initial marital satisfaction but did not add unique prediction of the rate of satisfaction change; observed marital interaction behavior did predict change over time (Karney & Bradbury, 1997). This finding is important because it separates a relatively stable individual difference from the interaction patterns through which relationships develop.
Other longitudinal work has found that neuroticism predicts later individual relationship satisfaction at the intrapersonal level (Schaffhuser et al., 2014). Across nine years, newer evidence also supports persistent actor-level associations (Bach et al., 2025). At the same time, a Swedish lifespan study found that adolescent neuroticism at age 15 did not significantly predict partner-relationship satisfaction in midlife, even though concurrent adult neuroticism was associated with satisfaction (Möller, 2004). Together these results caution against treating early personality as a fixed romantic destiny.
How neuroticism can shape romantic relationship experience
1. Emotional reactivity changes the intensity of ordinary relationship events
Neuroticism is associated with heightened negative-emotional reactivity to stressors in daily life. In a romantic context, the same external event—a delayed reply, a curt tone, a forgotten plan, a disagreement about chores—can generate different emotional responses in different people. Higher neuroticism may increase the probability that an event is experienced as more threatening, upsetting, or difficult to dismiss. This is one pathway by which general personality can enter the relationship without any partner intending harm.
Emotional reactivity should not be confused with a clinical symptom or with loss of control. It is a continuous individual-difference pattern. It is also shaped by the event itself. A severe betrayal, chronic disrespect, financial crisis, caregiving burden, or unsafe relationship can produce intense distress regardless of personality. Personality science cannot be used to reinterpret legitimate relationship problems as merely the reaction of a “sensitive” partner.
For the broader evidence on appraisal, reactivity, recovery, and stressor exposure, see Neuroticism and Stress: Perceived Stress, Reactivity, and Recovery. In romantic relationships, stress often matters because external demands and relationship processes interact: a person can arrive at an ordinary disagreement already physiologically tired, worried, or overloaded, increasing the chance that a small interpersonal cue becomes emotionally consequential.
2. Ambiguous partner behavior can be interpreted more negatively
One of the most relationship-specific findings concerns interpretation bias. Finn, Mitte, and Neyer developed a measure of relationship-specific interpretation bias: the tendency to interpret ambiguous partner and relationship scenarios in a more negative way. In a dyadic sample of 210 couples, this bias statistically mediated the association between neuroticism and relationship satisfaction even when general interpretation bias and attachment styles were controlled (Finn et al., 2013).
The mechanism is easy to understand conceptually. Ambiguous information invites interpretation. A partner who is quiet after work may be tired, preoccupied, irritated, disappointed, or simply enjoying silence. If ambiguous cues are more often assigned a negative relationship meaning, the interpretation can generate stronger emotion before the couple has established what actually happened. That emotion then changes behavior—perhaps prompting reassurance seeking, withdrawal, criticism, checking, or defensiveness—which can change the partner’s response in return.
This is a probabilistic cognitive tendency, not proof that a person’s interpretation is wrong. Sometimes the negative interpretation is accurate. Research on interpretation bias addresses average patterns across ambiguous scenarios; it cannot adjudicate the facts of a real conflict. The practical value lies in separating three layers that are often fused together: what was observed, what meaning was inferred, and what action followed.
3. Cognitive processes can connect personality with both partners’ satisfaction
A large longitudinal analysis of 2,090 heterosexual couples from the German pairfam study examined cognitive, emotional, and behavioral processes simultaneously using actor–partner interdependence mediation models. Neuroticism predicted variables in all three domains, and those variables in turn predicted both partners’ relationship satisfaction. Cognitive processes played a particularly important role at both intrapersonal and interpersonal levels (Kreuzer & Gollwitzer, 2022).
That result matters because it shifts the discussion away from a trait label and toward processes that happen inside an actual relationship. “High neuroticism” is not an explanation by itself. A scientifically useful explanation asks which interpretations, emotions, behaviors, and partner responses are occurring, under what stress conditions, and with what consequences over time.
4. Conflict behavior may carry part of the association
A seven-day daily diary study of 246 participants examined everyday relationship behaviors and found that a broad cluster of negative behaviors statistically mediated part of the association between neuroticism and relationship satisfaction; a narrower conflict-tactics cluster accounted for additional variance beyond the broader negative-behavior factor (Lange et al., 2025). Because this was observational mediation, the result should be interpreted as evidence for a plausible pathway rather than experimental proof that neuroticism causes those behaviors or that the behaviors fully explain the association.
Older observational research also links neuroticism to negative marital interaction. In a study of more than 400 couples using questionnaire and observational data, self-reported neuroticism correlated positively with negative interactions and negatively with global marital evaluations (Donnellan et al., 2004). The recurring implication is that relationship outcomes are connected not only to how partners feel but to how feelings become expressed during real interactions.
5. Attribution and aggression are distinct pathways, not synonyms for neuroticism
A three-wave study of 268 Chinese couples examined marital attribution and aggression as potential mediating processes. Spouses’ neuroticism was linked to their own and their partners’ marital satisfaction through several intrapersonal and interpersonal paths involving attribution and aggression, with some pathways specific to wives’ neuroticism in that sample (Cao et al., 2019). The cultural context and specific path pattern matter; these findings should not be converted into a universal rule about gender or into the claim that high neuroticism equals aggression.
Aggression is behavior. Neuroticism is a personality trait. A person can be highly neurotic and nonaggressive, and aggression can occur for many reasons unrelated to neuroticism. The distinction becomes especially important in harmful relationships: coercion, intimidation, threats, violence, and controlling behavior require direct attention to safety and behavior rather than a personality explanation.
6. Different components of negative emotionality may matter differently
Broad neuroticism contains heterogeneous emotional tendencies. A study of 301 couples compared anxiety, depression, and angry-hostility components and found negative actor effects for depression and angry hostility, while only angry hostility showed a significant negative partner effect on marital satisfaction in those analyses (Renshaw et al., 2010). This does not mean one facet determines relationship success. It shows why broad-domain scores can conceal different interpersonal pathways.
The same point applies across personality models. NEO PI-R facets, BFI-2 Negative Emotionality facets, Eysenck neuroticism scales, and IPIP measures are related but not interchangeable. A study using one operationalization cannot automatically establish a facet-specific conclusion for every other instrument.
7. Stress can amplify relationship-specific vulnerabilities
Romantic conflict rarely happens in a vacuum. Work pressure, financial strain, poor sleep, caregiving, illness, discrimination, uncertainty, and other stressors can increase the emotional load brought into a conversation. Neuroticism is associated with higher perceived stress and greater negative affective reactivity in many daily-life studies, so external stress can interact with trait sensitivity. This is better described as vulnerability under context than as a fixed deficit.
A seven-year longitudinal study of 103 married couples examined neuroticism together with conflict management, partner support, intimacy, power, and nonmarital stress in relation to internalizing symptoms. The pathways differed for husbands and wives in that sample, underscoring that relationship processes and external stress can combine in complex ways rather than following one universal chain (Brock & Lawrence, 2014).
Emotional reactivity is not the same as relationship instability
A person can react strongly in the moment and still participate in a stable, caring, well-repaired relationship. Emotional intensity becomes more consequential when it repeatedly changes interpretation and behavior in ways that create escalation, withdrawal, unresolved resentment, or repeated reassurance cycles. Conversely, a relationship can be unstable for structural reasons even when both partners are low in neuroticism.
This distinction prevents a common inferential error. Neuroticism is associated with negative affective reactivity, but relationship stability is a dyadic and contextual outcome. Stability depends on commitment, compatibility, life circumstances, conflict patterns, repair, support, safety, resources, and chance events, among other factors. No Big Five trait functions as a standalone predictor of whether a given couple will stay together.
Why partner effects vary across studies
It is tempting to imagine that if one partner is high in neuroticism, the other partner must become less satisfied. The data are more complicated. Some dyadic studies report partner effects, others find mostly actor effects, and the size of partner effects can depend on the outcome, sample, measurement, relationship duration, analytic model, and which components of neuroticism are examined.
One reason is that a partner does not experience the other person’s trait directly. The partner experiences behavior, communication, emotion, support, conflict, affection, withdrawal, repair, and the shared environment. Two people with similar neuroticism scores can express the trait very differently. A person who notices worry early and communicates it clearly may create a different dyadic pattern from someone whose worry becomes accusation or avoidance.
Another reason is statistical. Dyadic data violate the independence assumption used in ordinary individual analyses because partners’ experiences are correlated. Actor–Partner Interdependence Models explicitly model this interdependence. Findings from individual-level studies should therefore not be casually translated into claims about what one person’s score does to their partner.
Neuroticism, attachment, anxiety, and negative affect are related but distinct
Neuroticism vs anxious attachment
Anxious attachment concerns relationship-specific patterns involving fears of rejection or abandonment, heightened concern about partner availability, and strategies for seeking closeness or reassurance. Neuroticism is a broader personality dimension that extends beyond attachment relationships. They correlate, but one is not a renamed version of the other. For the attachment framework, see Attachment Styles in Relationships: Dating, Intimacy, Conflict, and Communication and Anxious Attachment Style: Signs, Triggers, Relationships, and What Research Shows.
Finn and colleagues’ 2013 study is especially useful here because relationship-specific interpretation bias statistically mediated the neuroticism–satisfaction association even after attachment styles were controlled. That result supports overlap alongside distinct explanatory value rather than identity between the constructs (Finn et al., 2013).
Neuroticism vs anxiety
Anxiety can be a state, a symptom dimension, a trait-like tendency, or part of a clinical disorder depending on how it is measured. Neuroticism is broader. Someone high in neuroticism may be prone to anxiety, sadness, irritability, worry, self-consciousness, or other forms of negative emotionality, but a neuroticism score does not diagnose an anxiety disorder.
Neuroticism vs negative affect
Negative affect often describes unpleasant emotional states such as fear, sadness, anger, or distress. Neuroticism describes a relatively stable tendency to experience such states more readily or intensely across time and situations. State negative affect can rise during one argument and fall later the same day; trait neuroticism is assessed as a broader pattern. Studies that measure momentary affect are therefore not measuring the same variable as a personality inventory.
Neuroticism vs emotional stability
Emotional stability is the opposite pole of the neuroticism dimension in many Big Five presentations. It is not a separate diagnosis or a guarantee of healthy relationships. Low neuroticism can be advantageous in stressful interactions because negative emotional responses may be less easily triggered, but extremely low distress sensitivity is not equivalent to empathy, communication skill, responsibility, or secure attachment.
Can romantic relationships change neuroticism?
Personality traits are relatively stable, but they are not fixed. Romantic relationships can become environments in which recurring interpretations and emotional experiences change. In a four-wave study of 245 young adult couples over nine months, decreases in relationship-specific interpretation bias predicted decreases in one’s own neuroticism, with a trend toward a partner effect (Finn et al., 2015). This finding is consistent with a transactional model in which changing relationship cognition may accompany personality development.
In older couples, Mueller and colleagues sampled momentary affect six times per day for one week and reassessed neuroticism 18 months later. Individuals higher in neuroticism showed stronger coupling of their positive affect with their partner’s positive affect. Stronger positive-affect coupling combined with a partner’s higher average positive affect was associated with later decreases in neuroticism, whereas lower partner positive affect was associated with increases in neuroticism (Mueller et al., 2021). The sample was small and age-specific, so the result is informative rather than universally generalizable.
These studies do not imply that a supportive partner can “cure” neuroticism. Trait change, state fluctuation, relationship satisfaction, and symptom improvement are different outcomes. A relationship may influence patterns that contribute to personality development while neuroticism retains substantial rank-order stability over time.
Does high neuroticism mean a relationship will fail?
No. The evidence supports increased average vulnerability, not inevitability. An aggregate correlation of −.238 leaves most individual variation unexplained by neuroticism alone. Relationships involving people high in neuroticism can be satisfying and durable, and relationships involving people low in neuroticism can be distressed or unsafe.
The better interpretation is probabilistic: higher neuroticism can increase the likelihood of certain experiences—worry, stronger negative reactions, threat-sensitive interpretations, prolonged distress—that may place more demand on a couple’s communication and repair processes. Whether those tendencies become chronic relationship problems depends on the partner, the interaction pattern, stress exposure, resources, and how both people respond.
It is also unhelpful to turn population research into interpersonal blame. If one partner says “our problems are because you are neurotic,” the label collapses a dyadic process into a single-person explanation. Relationship science is more informative when it identifies observable sequences: what happened, what each person inferred, what each felt, what each did, how the other responded, and whether the cycle changed over time.
What the evidence does and does not establish about conflict
The evidence supports an association between higher neuroticism and more negative relationship processes, including negative interpretations and certain conflict behaviors. It also supports the idea that these processes can statistically account for part of the association with relationship satisfaction. The evidence is much weaker for a universal causal statement such as “neuroticism causes conflict.”
First, many studies are observational. Even longitudinal mediation can leave unmeasured confounding. Second, conflict can affect emotion and personality-related behavior in the opposite direction. Third, partners select and shape environments together. Fourth, some stressful events are external to the relationship. Fifth, measures differ across studies. These limitations do not erase the association; they define what can responsibly be concluded from it.
A particularly useful example comes from Karney and Bradbury’s newlywed study: neuroticism was associated with the initial level of marital satisfaction, while observed interaction behavior predicted the rate of satisfaction change over four years (Karney & Bradbury, 1997). This pattern suggests that trait vulnerability and relationship process should be studied together rather than treating either as a complete explanation.
Practical implications for couples
Relationship science cannot convert a neuroticism score into a personalized prescription, but the process evidence points to several useful questions. These questions focus on modifiable interaction patterns rather than on blaming a trait.
Separate observation from interpretation
When conflict begins with ambiguity, identify the observable event before assigning meaning. “You looked at your phone while I was talking” is an observation; “you do not care about me” is an interpretation. This distinction is especially relevant because relationship-specific negative interpretation bias has empirical support as a pathway linking neuroticism and satisfaction.
Name the emotional state without turning it into a verdict
Strong emotion can be real without making every interpretation accurate. Saying “I am feeling rejected and activated right now” leaves more room for information than “you are rejecting me.” The goal is not to suppress emotion but to reduce the chance that temporary state intensity becomes a global claim about the relationship.
Track recurring cycles, not isolated incidents
Traits matter through repeated patterns. A single argument says little about neuroticism or relationship prognosis. Repeated sequences are more informative: ambiguous cue → negative interpretation → strong emotion → criticism or withdrawal → defensive partner response → confirmation of the original fear. Once a cycle is visible, partners can work on specific transition points rather than debating personality labels.
Distinguish external stress from relationship threat
If irritability and reactivity rise during periods of work overload, sleep loss, illness, financial strain, or caregiving, the relationship may be absorbing stress generated elsewhere. This does not make conflict unreal. It clarifies one source of vulnerability and can prevent partners from interpreting every stressed reaction as evidence that the bond itself is failing.
Use personality information descriptively, not diagnostically
A Big Five score can help describe recurring tendencies. It cannot establish that a partner has a disorder, attachment problem, or pathological relationship style. Nor should a raw score be used as a compatibility cutoff. Interpretation depends on the instrument, norms, scoring method, and population, and relationship outcomes depend on far more than one trait.
Keep harmful behavior behavior-specific
Neuroticism should never be used to excuse or explain away coercion, intimidation, threats, stalking, violence, or controlling behavior. Those are behaviors with direct consequences and safety implications. The appropriate unit of analysis is the behavior and its impact, not whether a personality trait might correlate with emotional sensitivity.
Research limitations that matter
Much of the classic literature on neuroticism and romantic relationships was conducted with heterosexual married or dating couples, often in Western samples. Some newer studies broaden national and age coverage, and the 2025 meta-analysis included a large body of work across countries and relationship stages, but generalization to every cultural context, sexual orientation, gender identity, relationship structure, and life stage remains an empirical question.
Measurement heterogeneity is another limitation. Neuroticism can be assessed with different instruments, relationship quality can be measured in different ways, and conflict can be self-reported, partner-reported, observed, or sampled in daily life. These methods capture overlapping but nonidentical phenomena. Apparent differences between studies may reflect both genuine population differences and differences in operationalization.
Finally, statistical mediation is not equivalent to experimentally demonstrated mechanism. Studies of interpretation bias, attribution, aggression, conflict tactics, and other mediators provide evidence consistent with pathways; they do not establish that changing one mediator will necessarily produce the predicted relationship outcome in every couple. Intervention research is required for stronger causal claims.
Frequently Asked Questions
Does high neuroticism ruin romantic relationships?
No. Higher neuroticism is associated with lower average relationship quality, but the effect is moderate and probabilistic. It does not determine whether a particular relationship will be satisfying, stable, or healthy.
Does neuroticism cause relationship conflict?
Research links higher neuroticism with negative interpretations, greater emotional reactivity, and some negative conflict behaviors, but most evidence is observational. It supports plausible pathways and vulnerability, not a universal one-way causal rule.
Why can neuroticism affect interpretation of a partner’s behavior?
Research on relationship-specific interpretation bias suggests that people higher in neuroticism may be more likely, on average, to interpret ambiguous partner and relationship scenarios negatively. The bias is a statistical tendency; a negative interpretation can still be correct in a specific situation.
Is neuroticism the same as anxious attachment?
No. Neuroticism is a broad personality dimension. Anxious attachment is relationship-specific and centers on concerns about rejection, abandonment, and partner availability. They can overlap while remaining distinct constructs.
Is neuroticism the same as anxiety?
No. Anxiety may be a temporary state, a symptom, a trait-like tendency, or part of a disorder. Neuroticism is a broader personality trait that includes proneness to several forms of negative emotion.
Can one partner’s neuroticism affect the other partner?
Yes, partner effects appear in some studies and outcomes, but they are less uniform than actor effects. The partner experiences the trait through concrete interactions such as emotion, communication, conflict, support, and repair.
Are actor effects stronger than partner effects?
Many dyadic studies find especially consistent actor effects, and some longitudinal datasets find little or no partner effect. The 2025 meta-analysis nevertheless found broadly similar differentiated male and female actor and partner correlations, so the balance depends on design and outcome.
Can a good romantic relationship reduce neuroticism?
Relationships can be associated with personality change, and longitudinal studies link changes in relationship-specific interpretation and affective coupling with later changes in neuroticism. This does not mean a partner can cure a personality trait or that every relationship produces the same change.
Can neuroticism change over adulthood?
Yes. Neuroticism is relatively stable but not fixed. Mean levels and individual trajectories can change over the lifespan, and relationship experiences are one of many contexts that may contribute to development.
Is high neuroticism a mental disorder?
No. Neuroticism is a dimensional personality trait. A high score is not a psychiatric diagnosis and cannot establish anxiety disorder, depression, OCD, PTSD, a personality disorder, or any other clinical condition.
Should couples use neuroticism scores to judge compatibility?
No universal evidence-based cutoff exists for romantic compatibility. Personality scores can describe tendencies, but relationship outcomes depend on multiple traits, interaction patterns, attachment processes, stress, values, circumstances, and the two partners’ ongoing behavior.
Conclusion
Neuroticism matters in romantic relationships because personality can shape how relationship events are perceived, felt, remembered, and acted upon. The strongest evidence shows a moderate negative association with relationship quality, especially through actor-level experience, while dyadic partner effects vary across studies. Relationship-specific interpretation bias, emotional reactivity, stress, attribution, and conflict behavior provide plausible and partially supported pathways.
The central scientific point is transactional rather than deterministic. Neuroticism can influence relationship processes, relationship processes can influence both partners, and recurring relationship experiences can accompany personality change. A trait score is therefore a starting variable in the model, not the conclusion. The most informative level of analysis is the recurring cycle connecting personality, context, interpretation, emotion, behavior, and partner response.
