A profound developmental experience is the emergence of adolescent romantic relationships and first feelings of love. However, the daily nature of feeling loved in adolescents' everyday lives is poorly understood. We investigated how daily stress severity was associated with adolescents' levels of feeling loved and whether romantic partner support moderated these associations.

Associations between effortful control and physical and mental health were examined among triads of mothers and twin children by simultaneously modeling the effects of one's own effortful control on one's own health (actor effects) with the effects of the other two family members' effortful control on one's health (partner effects). Families ( = 761 individuals; 254 families) included mothers ( = 39.98, = 5.

Neighborhood social processes may have important implications for parenting processes and ethnic-racial identity (ERI) processes and content in adolescence. Past research suggests that adolescents whose parents engaged in more cultural socialization, an important aspect of parental racial socialization, had higher levels of ERI processes and content. Parenting, however, is also situated within neighborhood contexts and can be influenced by resources available in neighborhoods.

Objectives: Sleep has consistently been shown to have a dyadic nature among married older adults; however, less is known about the influence of a spouses' social characteristics on one's own sleep. Focusing on older adults, we examined the association between one's spouses' educational attainment and one's own sleep duration.

Method: We used the 2004-2018 National Health Interview Survey (NHIS) to analyze heterosexual married adults aged 50-84 (N = 89,180).

During adolescence, interpersonal stressors such as peer rejection pose challenges to emotion regulation. Yet, very little is known about how these transactional processes unfold in adolescents' daily lives. This study investigated adolescents' (a) emotional reactivity to daily perceptions of peer rejection, which concerns concurrent changes in negative and positive emotions, and (b) emotional recovery from daily perceptions of peer rejection, which concerns subsequent changes in negative and positive emotions.

The present study examined daily ethnic/racial identity as a moderator for racial discrimination. The idiographic approach was used to understand when Black youth are at risk for negative outcomes in the context of racial discrimination. The current study assessed if within-person changes in racial centrality, private regard, and public regard moderated the daily relation between racial discrimination and depressive symptoms.

The college transition is uniquely challenging for many first-year students. Few studies have investigated developmental change in students' adjustment across this brief, but significant transition, nor the daily interpersonal dynamics that are associated with adjustment across this same time. Guided by ecological and stage-environment fit frameworks, this study examined trajectories of first-year students' positive and negative affect across the transition to college.

Romantic relationships, although increasingly normative during adolescence, also present unique developmental challenges that can portend psychological difficulties. Underlying these difficulties may be the degree to which daily romantic transactions potentiate fluctuations in negative mood. The present study examined associations between adolescents' daily romantic relationship experiences and their same-day negative affective states (i.

People's reports of their thoughts, feelings, and behaviors are used in many fields of biomedical and social science. When these states have been studied over time, researchers have often observed an unpredicted and puzzling decrease with repeated assessment. When noted, this pattern has been called an "attenuation effect," suggesting that the effect is due to bias in later reports.

Although much is known about people's attempts to cope with stressors, unmeasured heterogeneity in these stressors has made it difficult to assess the effectiveness of coping attempts. We remedied this problem by focusing on coping effectiveness in people preparing for a major, planned, uniform stressor, the Bar Examination. Within-person analyses of longitudinal data on anxiety in 321 persons over 35 days provided evidence on (a) coping effectiveness for the typical person, (b) how effectiveness changed across time, and (c) the extent to which individuals differed in their effectiveness.

Objective: This study documents the strength of relations between key parent and child behaviors as they occur during typical encounters for both mothers and fathers and determines whether there were shifts in the strength of relations between parent and child behaviors during early and middle childhood.

Design: Multivariate multi-level modeling was used to examine associations between three parent behaviors (respect for autonomy, stimulation of development, hostility) and two child behaviors (agency, negativity) as they occurred in typical parent-child activities at four time points from 54 months through 5 grade for 817 families.

Results: For mothers and fathers, respect for autonomy and stimulation were associated with child agency.

Social perception is among the most important tasks that occur in daily life, and perceivers readily appreciate the social affordances of others. Here, we demonstrate that sex categorizations are functionally biased towards a male percept. Perceivers judged body shapes that varied in waist-to-hip ratio to be men if they were not, in reality, exclusive to women, and male categorizations occurred more quickly than female categorizations (studies 1 and 4).

Objective: To investigate daily dietary adherence and diabetes-specific distress among older adults with type 2 diabetes mellitus (T2DM) as a function of spouses' diet-related support and diet-related control (persuasion and pressure) and whether these daily processes differ among couples who do and do not appraise responsibility for managing T2DM as shared.

Methods: End-of-day diaries were completed by 126 couples in which one partner had T2DM (patient) and the other did not (spouse). Using electronic diary methods, each partner independently recorded data for 24 consecutive days (patients recorded their day's dietary adherence and diabetes-specific distress; spouses recorded their day's involvement in patients' dietary management).

We investigated two types of negative and positive social control strategies, warning and encouragement, used by spouses to urge patients with type II diabetes to improve adherence to the diabetic diet. Warning refers to things a spouse may say or do to caution the patient about the consequences of eating a poor diet, and encouragement refers to things a spouse may say or do to promote healthier food choices by the patient. Our dyadic design (n=109 couples) assessed spouses' use of warning and encouragement (reported by spouses and by patients), as well as patients' reports of dietary adherence.

Although spousal support has been linked to positive outcomes in various health-related contexts, some research has found that the amount of social support provided to those who are chronically ill deteriorates over time. The current study refines the literature by considering multiple factors associated with spouses' provision of emotional support to partners with Type 2 diabetes. This diary study (N = 126 couples) examined the roles that stressor (disease severity and diabetes-specific anxiety), recipient (negative and positive affect), provider (negative and positive affect), and relationship (tension and enjoyment) factors play in spouses' provision of emotional support.

Although adults with anxiety disorders often report interpersonal distress, the degree to which anxiety is linked to the quality of close relationships remains unclear. The authors examined the relational impact of anxiety by sampling the daily mood and relationship quality of 33 couples in which the wife was diagnosed with an anxiety disorder. Use of a daily process design improved on prior methodologies by capturing relational processes closer to their actual occurrence and in the setting of the diagnosed partner's anxiety.

Although social support is thought to boost feelings of closeness in dyadic relationships, recent findings have suggested that support receipt can increase distress in recipients. The authors investigated these apparently contrary findings in a large daily diary study of couples over 31 days leading up to a major stressor. Results confirm that daily support receipt was associated with greater feelings of closeness and greater negative mood.

Whereas supportive interactions are usually studied from the perspective of recipients alone, the authors used a dyadic design to incorporate the perspectives of both provider and recipient. In 2 daily diary studies, the authors modeled provider reports of support provision in intimate dyads over several weeks. The 1st involved couples experiencing daily stressors (n = 79); the 2nd involved couples experiencing a major professional stressor (n = 196).

The recent growth in diary and experience sampling research has increased research attention on how people change over time in natural settings. Often however, the measures in these studies were originally developed for studying between-person differences, and their sensitivity to within-person changes is usually unknown. Using a Generalizability Theory framework, the authors illustrate a procedure for developing reliable measures of change using a version of the Profile of Mood States (POMS; McNair, Lorr, & Droppleman, 1992) shortened for diary studies.

Receiving support in committed relationships has frequently been associated with negative psychological outcomes in the recipient, such as increased distress. The authors hypothesized that these negative effects could be offset by support recipients' reciprocation of support, that is, by creating a sense of supportive equity. To investigate this hypothesis, the authors obtained daily reports of mood and of received and given emotional support from both partners in 85 couples throughout a 4-week period.
