Experience of Sibling Relationship: A Qualitative Study

Siblings share an intricate; beautiful yet complex relationship by design. Their bond transforms from fighting for attention from parents, rivalries in childhood to deeper understanding of each other's individuality; often coming to rely on each other and becoming each other's support system in adulthood. The study was conducted with an objective to find out the experience of sibling relationship. Qualitative research method was used with full informed consent from participants. In first phase of the study the researcher developed semi-structured interviewed schedule. In second phase the researcher conducted qualitative study was conducted among four young women, of age ranging from 20-25 years. The sample from various North Indian States: Haryana, New Delhi and Uttar Pradesh were purposively selected for the study. The interviews were recorded, all the recordings were listened again and again carefully in order to get a clear sense of participant’s explanation and views. They were transcribed into text and analyzed. The data analysis was performed simultaneously with data collection. The meaningful units were extracted from the participants in the form of open codes. After that, the codes were reviewed for several times and those which had similarity were classified into themes and sub-themes. Peer debriefing and member checking were used as strategies of rigor in the study. The findings of the study reported the relationship between siblings. The themes developed such as, Infights during childhood and/or adulthood, parental influences, evolution of sibling relationship in adults, common interests and appreciation and/or grievance. This study also provided insights into contrasting relationships shared by same sex siblings and opposite sex siblings in contemporary North Indian states.

Evaluation of Virtual Enhanced Child Adult Relationship Enhancement in Primary Care Intervention.

Because of COVID-19 pandemic social distancing requirements, the in-person Child Adult Relationship Enhancement in Primary Care (PriCARE) positive parenting intervention was adapted for virtual delivery. Objective was to evaluate the efficacy of the virtual PriCARE program to improve parenting capacity, decrease child behavioral problems, and decrease child maltreatment risk. Caregivers of children 2 to 6 years old recruited from pediatric primary care were randomized to PriCARE (n = 92) or waitlist control (n = 90). Dysfunctional parenting, positive parenting skills, child behaviors, and child maltreatment risk were measured at baseline and 2 to 3 months after intervention using the Parenting Scale (PS), Dyadic Parent-Child Interaction Coding System (DPICS), Eyberg Child Behavior Inventory (ECBI), and Child Abuse Potential Inventory (CAPI). Kruskal-Wallis test compared median change scores from baseline to follow-up by treatment arm. Of 182 enrolled caregivers, 92% (168) were mothers and 67% (122) completed study measures at baseline and follow-up. The median decrease (improvement) in total PS score was greater in the PriCARE group compared with the control group (-0.3 [IQR 0.69] vs -0.1 [IQR 0.56], p = 0.028) as was the median decrease (improvement) in ECBI problem score (-3 [IQR 9] vs -1 [IQR 7], p = 0.045) and ECBI intensity score (-9 [IQR 21] vs 0 [IQR 25], p = 0.006). Improvements in 4 positive parenting skills measured by DPICS were greater in the PriCARE group compared with the control group (all p< 0.003). Median decrease in CAPI abuse score did not differ significantly by study arm ( p = 0.055). The PriCARE virtual adaptation demonstrated promise in promoting positive parenting and decreasing child behavior problems.

Associations Among Hypersensitivity, Vagal Tone, and Mood State in Adults.

Although many previous studies have reported the relationship between hypersensitivity and vagal function in children, the relationship in adults is unclear. This study investigates the relationship between hypersensitivity and vagal function, discomfort to sensory stimuli, and daily mood states in healthy adults. Using a questionnaire, 39 healthy adults were divided into hypersensitivity and control groups. We compared the baseline respiratory sinus arrhythmia (RSA), reflecting vagal tone and reactivity, subjective discomfort to sensory stimuli, and daily mood status between groups. Those in the hypersensitivity group had significantly lower baseline RSA and were more likely to experience greater RSA variability and discomfort during exposure to sensory stimuli than the control group. We found no significant difference between groups in daily mood status. These findings suggest that vagal function is an important marker of hypersensitivity in healthy adults.

Emotional Invalidation and Relationship Quality: A Mediational Model Through a Social Learning Lens.

While we know childhood experiences are influential on a child's later socioemotional awareness and behavior, we are still searching for specific mechanisms that influence the transferability of childhood experiences and adult relationship functioning. In this study, we seek to further this area of investigation by examining the interpretation of ambiguous social interactions and perceptions of emotional invalidation as potential mediators of the relationship between perceptions of childhood emotional invalidation and current relationship quality. Participants completed online measures of hostile intent attributions, perceptions of childhood emotional invalidation, and current relationship quality with a significant other. They read emotionally provocative interpersonal scenarios and then reported likely emotionally invalidating reactions from their significant other to measure current perceptions of emotional invalidation. Results supported our hypotheses that perceptions of current emotional invalidation in a close, personal relationship would mediate the relationship between perceptions of childhood maternal emotional invalidation and both current relationship support and relationship conflict. Furthermore, the strength of this mediational pathway outweighed the influence of a more general hostile attribution bias. These findings have implications for prevention and intervention strategies designed to enhance interpersonal functioning.

Parenting practices and trajectories of proactive coping assets among emerging adult Black men.

Positive youth development (PYD)frameworks suggest that a critical response to investigating the challenges young Black men living in resource poor communities experience involves identifying contextual resources in young men's lives and personal assets that promote success. The following study examines heterogeneity in proactive coping assets trajectories, parental practices as predictors of developmental trajectories, and associated outcomes of each trajectory. The study sample consisted of Black emerging adult men living in rural Georgia (N = 504). At baseline, men were between the ages of 19 and 22 (Mage = 20.29; SD = 1.10). At wave four, the participants' mean age was 27.67 (SD = 1.39). Results of growth mixture modeling from waves 1 to 3 discerned three developmental trajectory classes of emerging adults' proactive coping assets: a high and increasing class (n = 247, 49%), a low and stable class (n = 212, 42%), and a moderate and decreasing class (n = 45, 9%). Trajectory classes were linked to baseline levels of parental support, coaching, and expectations. Analysis revealed that parental support and parental coaching predicted proactive coping asset trajectory class identification. Links were then investigated between emerging adults' proactive coping asset trajectory classes and wave four physical health, depression, and alcohol use. Results revealed significant associations between class identification, alcohol use, and physical health. Study findings provide evidence supporting the impact of parenting on emerging adult Black men, underscoring the need to expand resources that support parenting and emerging adult relationships.

Social relationships in adults who were adopted following institutional deprivation

Research examining the effects of severe, prolonged early deprivation has shown elevated rates of neurodevelopmental symptoms, which frequently persist into adulthood and are associated with functional and social relationship difficulties, as well as elevated rates of mental health problems. The behavioural manifestations of these symptoms closely resemble those of ADHD and also ASD. Here, we used qualitative methods to explore and characterise the social experiences and difficulties encountered by young adults exposed to profound early deprivation, in part to highlight any apparent parallels between the experiences in this group and those identified in typically developing samples with ADHD or ASD. To do so, we interviewed young adults and their adoptive parents ( N = 18) from the English and Romanian Adoptees study, about their social lives. Participants were keen to describe not only the challenges they faced but also adaptive responses. A semantic/descriptive thematic analysis revealed that the young adults strongly desired social relationships but struggled to navigate social norms, resulting in frustration and frequent loss of relationships. This was accompanied by strong feelings of loss and rejection, all of which were perceived to have a negative impact upon self-esteem and mental health. Adaptive strategies included the fostering of casual friendships with older individuals and seeking employment with strong social components. Similarities and differences between our findings and the social difficulties experienced by typically developing groups with neurodevelopmental problems, and adopted individuals more generally, are discussed.

A Systematic Review of the Relationship between Social Isolation and Physical Health in Adults.

Background: According to the World Health Organization, social isolation, particularly of older adults, is a public health issue endangering the well-being of individuals, families, and communities. Social isolation affects health through biological, behavioral, and psychological pathways and is associated with physical and psychological/emotional well-being, increases morbidity and mortality rates, and lowers quality of life. Purpose: This systematic review examined the relationship between social isolation and physical health, including subjective and objective dimensions, and factors that influence this relationship in adults. Methods: This systematic review examined six electronic databases covering the field of health and human services and included results from 1 January 2017 to 10 March 2023 with key terms including adult social connection or social isolation coupled with health, physical, psychological, emotional, mental, or behavioral. The initial search yielded 925 research articles across all databases and was narrowed to 710 when the decision was made to focus on social isolation and physical health. Covidence was used throughout the retrieval and appraisal process, as provided in a PRISMA flow diagram. Twenty-four studies that scored 90 or above in the appraisal process were included in the systematic review. Results: The studies represented included seven studies conducted in the United States and seventeen studies conducted internationally. Regarding study design, twenty-three studies were quantitative, one was qualitative, and one was mixed methods. The majority of quantitative studies were correlational in design with nine being longitudinal. The majority of studies were based on large national data sets representing in total 298,653 participants aged 50 and older. The results indicate that social isolation is related to increases in inflammatory biomarkers associated with diseases, all-cause mortality, lower expectations of longevity, and frailty. In addition, social isolation was associated with cognitive decline and disruptions in sleep. Poor oral health increased social isolation. The results further indicated that decreased physical performance/function and a decline in physical activity were associated with social isolation, as well as decreased overall physical health, poor health behaviors, and self-care, and decreased health-related quality of life. Further research is warranted to examine the possible bidirectionality of these relationships and possible mediating, moderating, or confounding variables. Implications: Future research is needed to explore the biological and behavioral pathways in which social isolation negatively impacts physical health. Going forward, studies are needed that move beyond descriptive, exploratory methods and integrate data from qualitative and mixed-method designs that will inform the development and testing of a conceptual framework related to social isolation and health. By advancing the science behind social isolation, comprehensive interventions can be identified and tested with implications at the individual, family, community, and societal levels to reduce social isolation, particularly among adults, and improve health and quality of life.

Behavioral pathways from sibling relationships in adolescence to romantic partnerships in adulthood.

Sibling relationships in adolescence provide rich and relevant socializing opportunities for developing early adult romantic relationships, but much less is known regarding the effect of siblings on future romantic partnerships. Using a prospective, longitudinal design, we investigated the association between observed positive behaviors (warmth, support, positive communication), sibling pairs during adolescence (7th, 8th, 9th, and 10th grades), and the same observed behaviors between adult romantic partners nearly two decades later (M age = 31 years old). In structural equation models (SEMs), we tested four dyadic pathways of interest: (1) individual behavioral continuity; (2) evocative partner effects; (3) sibling modeling; and (4) sibling-to-partner matching. In multiple group analyses, we also investigated gendered socialization effects for different sibling dyads (i.e., brother-brother; sister-sister; and mixed-sex sibling pairs). Results showed strong continuity from adolescent behavior toward their sibling to the same behavior toward their romantic partner in early adulthood, but there was no evidence for sibling modeling effects nor for sibling matching. We also found significant differences between sister-sister sibling dyads compared to brother-brother and mixed-sex sibling dyads for the evocative pathway. Findings highlight the "long view" of positive adolescent behavior in sibling relationships for shaping future romantic partnerships in adulthood.

Computational analysis of value learning and value-driven detection of neutral faces by young and older adults

The rapid detection of neutral faces with emotional value plays an important role in social relationships for both young and older adults. Recent psychological studies have indicated that young adults show efficient value learning for neutral faces and the detection of “value-associated faces,” while older adults show slightly different patterns of value learning and value-based detection of neutral faces. However, the mechanisms underlying these processes remain unknown. To investigate this, we applied hierarchical reinforcement learning and diffusion models to a value learning task and value-driven detection task that involved neutral faces; the tasks were completed by young and older adults. The results for the learning task suggested that the sensitivity of learning feedback might decrease with age. In the detection task, the younger adults accumulated information more efficiently than the older adults, and the perceptual time leading to motion onset was shorter in the younger adults. In younger adults only, the reward sensitivity during associative learning might enhance the accumulation of information during a visual search for neutral faces in a rewarded task. These results provide insight into the processing linked to efficient detection of faces associated with emotional values, and the age-related changes therein.

Association between urinary metals and prostate-specific antigen in aging population with depression: a cross-sectional study

ObjectiveThis study aims to investigate the impact of depression and urinary metals on Prostate-Specific Antigen (PSA).MethodsAnalysis was conducted on 1901 samples collected from the National Health and Nutrition Examination Survey (NHANES) database between 2001 and 2010. Analytical methods included stepwise multiple linear regression (MLR) analysis of the overall population’s urinary metals and PSA relationship, analysis of urinary metals and PSA relationship in older adults and BMI subgroups, analysis of urinary metals and PSA relationship in the depressed population, and restricted cubic spline (RCS) analysis. A significance level of p &amp;lt; 0.05 was considered statistically significant.ResultsIn the stepwise multiple linear regression, beryllium (Be) showed a dose–response association with PSA (third quartile: β = 0.05, 95%CI (0.02, 0.09); fourth quartile: β = 0.07, 95%CI (0.02, 0.12), p trend = 0.048). Subgroup analysis indicated that in individuals aged &amp;gt;60, Be at Q4 level [β = 0.09, 95%CI (0.05, 0.21)] exhibited a dose–response correlation with PSA. In the population with 25 ≤ BMI &amp;lt; 30, Be might more significantly elevate PSA, with Q4 level having a pronounced impact on PSA levels [β = 0.03, 95%CI (0.02, 1.27)]. In the depressed population, urinary cadmium (Cd) levels showed a significant positive dose–response relationship, with Q4 level of Cd having the maximum impact on PSA [β = 0.3, 95%CI (0.09, 0.49)].ConclusionIndividuals exposed to beryllium (Be), especially the older adults and overweight, should monitor their PSA levels. In depressed patients, cadmium (Cd) levels may further elevate PSA levels, necessitating increased monitoring of PSA levels among males.

Maladaptive personality traits and older adult relationship satisfaction: A co-twin control approach to understanding associations.

Maladaptive personality traits have been implicated in romantic relationship dissatisfaction, but the etiology of those links and the degree to which they extend to other types of relationships are unclear. The purpose of this study was to examine associations between maladaptive personality traits and satisfaction in various relationships using a co-twin control design to identify potential environmental contributions. The sample consisted of 1340 older adult twin participants from the Minnesota Twin Registry (Mage = 70.3) that completed the Personality Inventory for DSM-5 Faceted Brief Form and Network of Relationships Inventory (Revised for Older Adults). Several maladaptive personality traits were phenotypically associated with relationship dissatisfaction, with detachment and negative affect having the largest effects. Further, within twin pair differences in detachment and negative affect were associated with greater relationship dissatisfaction, suggesting that observed associations were mediated partly by the unique environment, not solely the result of genetic and familial confounding. Both phenotypic and co-twin associations were strongest overall in the romantic partner relationship. These findings support the notion that maladaptive personality traits are implicated in interpersonal dysfunction across multiple domains.

Self-Care of Diabetes and Diabetes Distress in Non-Hispanic Black Adults With Type 2 Diabetes.

The purpose of the study was to describe the level of self-care of diabetes and diabetes distress and examine their relationship in non-Hispanic Black adults living with type 2 diabetes. This cross-sectional, correlational study was conducted with 275 non-Hispanic Black adults with type 2 diabetes in North Carolina over 10 weeks, July 2022 to September 2022. An online survey collected sociodemographic and clinical characteristics, self-care measures of diabetes, and diabetes distress. The theory of self-care of chronic illness guided the study. Median regression examined the relationship between self-care of diabetes and diabetes distress. Of the 275 participants, over half reported a diagnosis of type 2 diabetes at younger ages than expected, with a mean age of 40. The self-reported mean A1C of 9% exceeded the recommended goal of <7%, with an average of 2 diabetes-related comorbidities. The self-care of diabetes scale scores were low, and total diabetes distress scores were high. Significant positive associations were found between total diabetes distress and self-care monitoring and self-care management. In this sample, non-Hispanic Black adults had low levels of self-care of diabetes and high levels of diabetes distress. The findings indicate a relationship between self-care of diabetes and diabetes distress; as diabetes distress increases, so do the attempted activities of self-care of diabetes. Health care professionals in diabetes care are uniquely positioned to address further the behavioral aspects of diabetes management, particularly diabetes distress, to support non-Hispanic Black adults living with type 2 diabetes.

Additive and Moderating Effect of Parents and Friends on Health and Behavior Outcomes During Emerging Adulthood

Relationships with parents and friends may work together to increase the risk of adjustment problems in emerging adulthood. However, it is still undetermined if social relationships act in an additive (i.e., serve as unique predictors) or moderating (i.e., interact with other predictors) fashion. In a cross-sectional sample of 859 female college students ( M age = 19.53, SD = 1.49; 73.9% White) from a large university in the south-central United States, we assessed how parents and best friends impact emerging adult internalizing symptoms, risky behavior, and health problems. We found that low levels of best friend risky behavior attenuated the links between father-emerging adult relationship quality and risky behavior and internalizing symptoms, and high levels of father-emerging adult relationship quality magnified the association between mother-emerging adult relations and internalizing symptoms. Ultimately, these results indicate that relationships with parents and friends served as additive or unique predictors of emerging adult health and behavior.

Human shoulder anatomy: new ultrasound, anatomical, and microscopic perspectives

This study aimed to describe the shoulder anatomy, together with the anatomical relationships in adults and early stages of development. The shoulder muscles were studied from ultrasound, anatomical, and microscopic perspectives in a sample of 34 human shoulders. Thickness measurements were taken of the tendons and fasciae of the subscapularis, long head tendon of the biceps brachii, supraspinatus, infraspinatus, and teres minor. Ultrasound and dissection techniques are strongly correlated. However, the measurements obtained from the dissection technique were superior to those obtained from the ultrasound in all cases, except for the thickness of the long head tendon of the biceps brachii, the teres minor tendon, and the fascia thickness of the infraspinatus. In addition, the study of shoulder anatomy revealed no differences between females and males. Relevant findings from dissection included a clear overlap between the infraspinatus and supraspinatus, which shared tendon fibers, and a similar connection between the transverse ligament of the long head tendon of the biceps brachii and the subscapularis, which created a more interconnected shoulder function. The study of the anatomical measurements shows an underestimation of the shoulder measurements in the ultrasound compared with the dissection technique, but a high correlation between the measurements made by the two techniques. We present reference values for the tendon and fascia thicknesses of the rotator cuff, with no differences observed by gender. The relationships between shoulder structures described in the anatomical study imply as well that, in the event of an injury, adjacent tissues may be affected. This extended information may facilitate future optimal clinical explorations.

Discrepancies in parents’ perceptions of adult children’s well-being: evidence from mother–father–child triads

ABSTRACT Most studies of discrepancies in parents’ reports about children’s psychological problems address younger children and psychological problems. The current contribution shifts the focus to adult children and to well-being. In adult intergenerational relationships, knowledge of children’s well-being is more uncertain and there is more room for disagreements to arise, especially in the context of divorce. We analyzed Dutch multi-actor survey data, using a sample of triads of adult children, fathers, and mothers (N = 1,440). Two hypotheses were tested about the origins of discrepancies using structural equation models in which child well-being reports were included of parents and self-reports of children. The analyses supported the notion of relational specificity: when parents have a closer and more harmonious relationship with the child, they evaluate the child more positively than the other parent, after controlling for adult children’s self-reports of well-being. Qualified support was obtained for the depression-distortion hypothesis, with mothers who have higher well-being themselves being more positive about the child. Discrepancies were larger among separated parents than among married parents and parent-stepparent combinations. The conclusion is that parents do not always have similar views of adult children’s well-being and that disagreements are systematic, with bias stemming from the informant and the relationship.

Strengths, Struggles, and Strategies: How Adults with Serious Mental Illness Navigate Long-Term Romantic Relationships.

Married individuals and those in committed romantic relationships generally report having better mental health outcomes than their single or divorced counterparts. However, studies of romantic relationships for adults with mental illness have often ignored rewarding aspects of romantic relationships and have focused primarily on relationship difficulties. In this study, 23 adults with serious mental illness in long-term romantic relationships described their relationship strengths and struggles in small focus group discussions. Content analysis was used to characterize themes from participant accounts. Overall, participants described deep emotional bonds with their partners, a mutual willingness to work on their relationship, and good communication skills as relationship strengths. Mental health symptoms and internalized stigma were identified as major contributors to relationship struggles. Participants spontaneously identified intentional strategies that they used to navigate mental health challenges in their relationship that included self-directed, partner-directed, and couple-directed actions. Implications of findings for research and practice are discussed.

The role of perceived negative partner behavior in daily snacking behavior: A dynamical systems approach

Past work suggested that psychological stress, especially in the context of relationship stress, is associated with increased consumption of energy-dense food and when maintained for long periods of time, leads to adverse health consequences. Furthermore, this association is moderated by a variety of factors, including emotional over-eating style. That being said, few work utilized a dynamical system approach to understand the intraindividual and interindividual fluctuations within this process. The current study utilized a 14-day daily diary study, collected between January–March 2020, where participants reported their partner's negative relationship behavior and their own snacking behavior. A differential equation model was applied to the daily dairy data collected. Results showed that snacking behavior followed an undamped oscillator model while negative relationship behavior followed a damped coupled oscillator model. In other words, snacking behavior fluctuated around an equilibrium but was not coupled within dyadic partners. Negative relationship behavior fluctuated around an equilibrium and was amplified over time, coupled within dyadic partners. Furthermore, we found a two-fold association between negative relationship behavior and snacking: while the association between the displacement of negative relationship behavior and snacking was negative, change in negative relationship behavior and snacking were aligned. Thus, at any given time, one's snacking depends both on the amount of negative relationship behaviors one perceives and the dynamical state a dyad is engaging in (i.e., whether the negative relationship behavior is “exacerbating” or “resolving”). This former association was moderated by emotional over-eating style and the latter association was not. The current findings highlight the importance of examining dynamics within dyadic system and offers empirical and methodological insights for research in adult relationships.

Concerns about fertility, social appearance, and relationships in young adults with polycystic ovary syndrome

ABSTRACT Background Polycystic Ovary Syndrome (PCOS), affecting 1–11% of reproductive-age women, is characterised by many symptoms that cause important concerns especially in young adults. Objective This study aimed to evaluate the concerns about fertility, social appearance, and relationships in young adults with PCOS. Methodology This descriptive study included 140 young female adults aged 18–26, who were diagnosed with PCOS, agreed to participate in the onlineresearch through social media between July and December 2022 in Turkey. Data were collected using the ’Participant Interview Form’ and the ”Social Appearance Anxiety Scale (SAAS). Results The mean age of the participants was 22.1 ± 2.1. As the most common symptoms, 78.6% experienced menstrual irregularities, 16.4% were overweight, 7.1% were obese, 67.1% had hirsutism and 65.7% had acne. Most of the participants expressed concerns about future infertility (72.9%), and worried about being unable to conceive due to PCOS in the future (sometimes = 61.4%). Over eighty percent of the participants expressed some level of dissatisfaction with their physical appearance. They commonly believe that their self-esteem, emotionalstate, social relationships and partner relationships could be negatively affected by PCOS. SAAS scores were significantly increased by low income, high BMI, hirsutism, dissatisfaction with physicalappearance, low self-esteem, emotional problems and concerns related to social and partner relationships (p < 0.05). Conclusion Young adults have common concerns about the potential negative impacts of PCOS on fertility, social appearance, and relationships. Health professionals should be aware of their counselling needs about the possible physical and psycho-social effects of PCOS and provide continuous care and support.

Discordant and Concordant Substance Use and Daily Partner Violence in Adolescent and Young Adult Relationships With Baseline Dating Violence

PurposeIntimate partner violence (IPV) and substance use in adolescents and young adults (AYAs) are significant public health issues in the United States. Together, they can harm emotional regulation and romantic relationship functioning. This study examines the role of concordant and discordant substance use on IPV within AYA relationships. MethodsA prospective cohort of community-recruited AYA women in a heterosexual dating relationship with past-month IPV completed four months of daily surveys via a cell phone. Each day, participants reported any IPV perpetration and/or victimization, their alcohol and drug use, and observed partner substance use. Concordant substance use was coded when the participant and partner used drugs or alcohol on the same day. Discordant use was coded when only the participant or partner used drugs or alcohol on a given day. Alcohol and drug use were modeled separately. Generalized estimating equations accounted for the correlation of repeated measures. ResultsParticipants (N = 143) were 18.2 (1.1) years old, 93% African American race. Discordant alcohol and drug use was associated with same-day victimization, perpetration, and co-occurring violence compared to concordant nonuse. Similarly, concordant alcohol use, drug use, and alcohol/drug use were associated with increased odds of victimization, perpetration, and co-occurring violence compared to concordant nonuse. DiscussionDaily data illustrated that dyadic patterns of substance use are associated with IPV. These findings may facilitate the development of effective and developmentally appropriate IPV intervention programs for AYA that also integrate strategies to reduce substance use.

A Study on the Impact of Ego Defense Mechanisms on the Formation of Close Relationships in Young Adults

A Study on the Impact of Ego Defense Mechanisms on the Formation of Close Relationships in Young Adults
