Social Media Friendship Jealousy.

A new measure to assess friendship jealousy in the context of social media was developed. This one-factor, seven-item measure was psychometrically sound, showing evidence of validity and reliability in three samples of North American adults (Study 1, n = 491; Study 2, n = 494; Study 3, n = 415) and one-, two-, and three-year stability (Study 3). Women reported more social media friendship jealousy than men (Studies 2 and 3) and younger women had the highest levels of social media friendship jealousy (compared with younger men and older men and women; Study 2). Social media friendship jealousy was associated with lower friendship quality (Study 1) and higher social media use and trait jealousy (Study 2). The relation between social media friendship jealousy and internalizing symptoms indicated positive within time associations and longitudinal bidirectional relations (Study 3). Specifically, social media friendship jealousy predicted increases in internalizing problems, and internalizing problems predicted greater social media friendship jealousy accounting for gender and trait levels of social media friendship jealousy and internalizing problems. Anxious and depressed adults may be predisposed to monitor threats to their friendships via social media and experience negative consequences because of this behavior. Although social media interactions can be associated with positive well-being and social connectedness, our results highlight that they can also undermine friendships and mental health due to jealousy.

Measurement Invariance of the Multidimensional Jealousy Scale and Quality of Relationships Inventory (Friend).

The aim of this study is to measure the invariance of the Multidimensional Jealousy Scale (MJS) and of the Quality of Relationships Inventory (Friend) (QRI-F) across gender, age, education, and being in a romantic relationship in a Portuguese sample (N = 662). A confirmatory factor analysis was performed to test the fit of different potential factor structures. The results pointed out that both MJS and QRI-F were most suitable if represented by three first-order factors correlated between them. Results from multi-group analyses suggested there was factorial invariance for these structures across groups, suggesting that the MJS and the QRI-F provide, respectively, an assessment of romantic jealousy and quality of relationship that are equivalent across gender, age, education, and being in a romantic relationship. The study established the strong psychometric properties of its instruments, validating reliability and convergent and discriminant validity, thereby bolstering the research's overall credibility. Additionally, cognitive jealousy is primarily influenced by heightened conflict values, with education, relationship status, and gender moderating the associations between QRI-F dimensions and MJS behavioral and cognitive jealousy. The research offered in-depth perspectives on jealousy, underscoring its diverse manifestations across demographic variables and illuminating the complexities within the dynamics of friendships.

Clinical Characterization, Course, and Treatment of Othello Syndrome: A Case Series and Systematic Review of the Literature.

BACKGROUND: Othello syndrome (OS) is a condition characterized by a delusion of jealousy that one's spouse is having extramarital affairs. As in the eponymous Shakespearean tragedy, there is an unfortunate risk of violence. For patients with these symptoms, consultation-liaison psychiatrists may be asked to assist with evaluating the differential diagnosis, assessing safety, and developing treatment options. OBJECTIVE: This study's objective was to solidify current knowledge of the clinical presentations and management of OS through a systematic review of the literature and description of 2 new cases. METHODS: We conducted a literature search from the start of relevant databases through August 2023 to identify English language case reports of adults (≥18 years) with OS that described clinical evaluations, biological treatments, and outcomes. We extracted demographics, proposed etiologies, treatment choices and responses, duration of delusions, comorbid psychiatric symptoms, neuro-radiographic findings, and presence of physical violence. We reported clinical findings for 2 new cases. RESULTS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we screened 705 abstracts and conducted full-text reviews of 118 articles to identify 73 cases published from 1983 to 2023 meeting inclusion criteria. The mean age was 58.2 years with male predominance (M:F = 1.88). Etiologies included primary psychiatric disorders (16, 22%), other medical conditions (38, 52%), and medications or other substances (19, 26%). Delusional disorder, cerebrovascular accident, and dopaminergic agonists were the most common etiologies, respectively, in these groups. Antipsychotics were the most common treatment (57, 78%). Symptom remission was reported in 51 (70%) cases. The average duration of OS was 39.5 months. Of 32 cases reporting brain imaging insults, 12 of 20 (60%) showed right-sided lesions, and 8 of 20 (40%) showed left-sided lesions, with 9 of 32 (28%) located in the frontal lobes. The most commonly co-existing psychiatric symptom was depression (14, 19%). Violence was reported in 25 cases (34%). Our 2 new cases were consistent with these findings. CONCLUSIONS: OS may be a manifestation of several neuropsychiatric conditions, primarily delusional disorder, cerebrovascular accident, Alzheimer's dementia, and the use of dopaminergic agonists. One-third of cases include violent behaviors. It appears to respond to antipsychotic medications, but treatment is delayed more than 3 years on average. Available data have not localized OS to a specific brain region.

El centenario de dos Castillas del Pino: el intelectual y el psiquiatra / The Centenary of Two Castillas del Pino: the Intellectual and the Psychiatrist

Con ocasión del centenario de Carlos Castilla del Pino (15 de octubre de 2022) se analiza la relación que existe entre sus dos facetas públicas: la psiquiátrica y la intelectual. Al revisar cronológicamente sus publicaciones aparecen claramente cuatro etapas que oscilan entre esos dos polos: empiezan siendo puramente psiquiátricas (1946-66), se desplazan lue-go hacia lo ensayístico (1966-71), vuelve a predominar la psiquiatría (1971-87) y finalmente se decanta por el ensayo literario-memorístico (1989-2010). El análisis de la recepción que tuvo Castilla del Pino por la psiquiatría académica (hostil) y por la intelectualidad progresista (entusiasta), junto con algunos testimonios personales, acaba de ilustrar esas dos facetas de su personalidad. (AU)

On the occasion of Carlos Castilla del Pino's centenary (15 October 2022), we analyse the relationship between his two public facets: the psychiatric and the intellectual. A chronological review of his publications clearly shows four stages that os-cillate between those two poles: they begin as purely psychiatric (1946-66), then move towards essays (1966-71), psychiatry again predominates (1971-87) and finally he opts for literary-memoiristic essays (1989-2010). The analysis of Castilla del Pino's reception by academic psychiatry (hostile) and by the progressive intelligentsia (enthusiastic), together with some personal testimonies, just illustrate these two facets of his personality.

The Relationship between Jealousy and Mate Retention Strategies in Romantic Relationships among Women during the COVID-19 Pandemic.

Jealousy and mate retention have received attention in research over the last few decades. Despite this, most of the research has examined male jealousy and male mate retention, emphasizing cost-inflicting behavior due to its role in relationships and domestic violence. The aim of this study was to investigate the relationship between jealousy and all mate retention strategies in romantic relationships among women during the COVID-19 pandemic. The sample consisted of 772 Croatian women aged 19 to 40 who were in a heterosexual relationship at the time. This study was conducted online, and the participants completed the Multidimensional Jealousy Scale and Mate Retention Inventory. The results showed that cognitive, emotional, and behavioral jealousy were positively correlated with all mate retention strategies, which indicates that a stronger experience of jealousy can be expected to result in more frequent use of all partner retention strategies. We also found that all three dimensions of jealousy and relationship length positively predicted both cost-inflicting and benefit-provisioning mate retention behavior, whereas age was a negative predictor of benefit-provisioning behavior only. The findings of this study suggest that, although jealousy can substantially explain interpersonally risky and damaging behavior in relationships, it can also explain affectionate and attentive behavior, to some extent.

Validation of the Short-Facebook Jealousy Scale among Colombian Men and Women

Social networks, particularly Facebook, influence romantic relationships, as they can generate jealousy and conflict between members of the couple. The Facebook Jealousy Scale (FJS) is an instrument that assesses jealousy about using Facebook, but no similar instrument is available in Colombia. The main aim was to examine the psychometric properties of the FJS in a Colombian sample of 485 men and 727 women. Participants answered the socio-demographic questionnaire, the adaptation of the Facebook Jealousy Scale, Romantic Partner Conflict Scale, Rosenberg Self-Esteem Scale and Romantic Jealousy Scale. The final version of the FJS was made up of 15 items which were distributed across three dimensions: Partner's Activity, Partner's Surveillance, Partner's Romantic and Sexual relationship. Ordinal's alpha values from its three factors ranged between .90 and .95. Concurrent validity was also provided, as the measure was associated with dimensions from partner conflict, self-esteem, and romantic jealousy. An invariance test by gender was also performed, resulting in compliance with metric invariance. Therefore, the FJS is a useful tool for clinicians and researchers who work on issues related to romantic relationships. Research analyzing Facebook jealousy provides an interesting indicator of couple's monitoring and controlling behaviors, which are features of psychological abuse, a subtype of intimate partner violence.

Las redes sociales, particularmente Facebook, influyen en las relaciones sentimentales, ya que pueden generar celos y conflictos entre los miembros de la pareja. La Escala de Celos de Facebook (FJS) es un instrumento que evalúa los celos por el uso de Facebook, y no hay ningún instrumento similar disponible en Colombia. El objetivo principal fue examinar las propiedades psicométricas del FJS en una muestra colombiana de 485 hombres y 727 mujeres. Los participantes completaron un cuestionario sociodemográfico, la adaptación de la Escala de Celos de Facebook, la Escala de Conflicto de Pareja Romántica, la Escala de Autoestima de Rosenberg y la Escala de Celos Románticos. La versión final de la FJS estuvo conformada por 15 ítems que, a su vez, conformaron tres dimensiones: Actividad de la pareja, Vigilancia de la pareja, Relación romántica y sexual de la pareja. Los valores de alfa ordinal de los tres factores oscilaron entre .90 y .95. También se demostró validez concurrente con otras dimensiones relacionadas con conflicto en la pareja, autoestima y celos románticos. El análisis de invarianza según género resultó en un nivel de invarianza métrica. El FJS es una medida que puede ser útil para la práctica clínica y los investigadores que trabajan en temas relacionados con las relaciones románticas. La investigación que analice los celos asociados al Facebook ofrecerá un interesante indicador de la supervisión en el contexto de pareja y las conductas de control, elementos clave del abuso psicológico, un subtipo de la violencia de pareja.

Maintenance in relationships, satisfaction, jealousy, and violence in young couples: a network analysis.

BACKGROUND: The study explores the associations among Relationship Maintenance, Satisfaction, Jealousy, and Violence in young Peruvian couples, particularly in a post-pandemic context, using a network analysis. METHODS: Eight hundred thirty-two participants aged 18-30 (M = 20.94, SD = 2.29), with 645 females (77.50%) and 187 males (22.50%), were involved. The study aimed to discern relationships among network nodes, emphasizing the link between Relationship Maintenance dimensions and Jealousy and Violence. The research also sought the central node in the network and examined gender-specific node connections, using the SMOTE algorithm for gender data balance. RESULTS: Findings revealed a direct connection between Complementarity and Jealousy, implying intense shared interests can lead to unhealthy dependence. An inverse relationship was seen between Companionship and Violence. Satisfaction was pivotal, showcasing its importance in romantic relationship success. Additionally, the study shows men prioritize Companionship and Sharing, possibly due to cultural norms, while women focus on the Companionship-Complementarity bond, indicating mutual support. CONCLUSIONS: The research emphasizes the critical role of maintenance variables in determining Satisfaction, Jealousy, and Violence in relationships. The pandemic's influence on romantic dynamics is evident, emphasizing the importance of Satisfaction. Future studies should focus on gender equity and further explore these relationships.

The Impact of Romantic Attachment Styles on Jealousy in Young Adults.

Background: Romantic attachment is reflected in various aspects of dyadic interaction in a couple, since it is a self-reinforcing system of cognitive, emotional and behavioral patterns. Romantic jealousy was shown to be associated with dimensions of attachment insecurity in various studies worldwide. Objectives: To identify differences in expressions of romantic jealousy based on romantic attachment style. To determine the influence of attachment-related anxiety and attachment-related avoidance on cognitive, emotional, and behavioral jealousy. Design: The sample comprised 171 heterosexual individuals. The "Experiences in Close Relationships - Revised" questionnaire (ECR-R; Fraley, Waller, & Brennan, 2000; adapted for Russian by Chursina, 2022) and "Multidimensional Jealousy Scale" (MJS; Pfeiffer, & Wong, 1989) were used. Results: A number of significant differences were identified between insecure and secure attachment styles. Avoidant attachment is characterized by cognitive jealousy, ambivalent attachment is characterized by cognitive and behavioral jealousy, while dismissing attachment showed no significant differences in the manifestations of jealousy in comparison with secure attachment style. Emotional jealousy is equally characteristic of all types. The primacy of romantic attachment in relation to cognitive and behavioral jealousy was also proved. Conclusion: The experience of jealousy differs among romantic attachment styles. Attachment-related anxiety is a predictor of intrusive thoughts and behavioral manifestations of jealousy, while attachment-related avoidance is less, the greater the manifestation of jealousy behaviors.

Ideological Mate-guarding: Sexual Jealousy and Mating Strategy Predict Support for Female Honor.

Feminine honor dictates that women should cultivate a reputation for sexual purity via behaviors such as dressing modestly and maintaining virginity before marriage. The dominant explanation for people's support for feminine honor is that female infidelity threatens male partners' honor. Beyond this, the literature affords little understanding of the evolutionary and psychological origins of feminine honor. We propose that feminine honor functions as an ideological form of mate guarding that is shaped by sexual jealousy and mating strategy. Two correlational studies (N = 892) revealed support for predictions derived from this ideological mate-guarding account. In Study 1, dispositional jealousy and mating strategy (more monogamous orientation) predicted male participants' support for a mate's (especially a long-term mate's) feminine honor. Moving beyond mate preferences, in Study 2 male and female participants' dispositional jealousy and mating strategy predicted support for feminine honor of women in general. Results applied beyond masculine honor norms, religiosity, political conservativism, and age. These findings enhance the understanding of the origins and maintenance of feminine honor and related norms and ideologies that enable control over women's socio-sexual behavior.

Relationship risk factors for intimate partner violence among sexual and gender minorities: A multilevel analysis.

Intimate partner violence (IPV) is alarmingly prevalent among sexual and gender minority youth assigned female at birth (SGM-AFAB), making it important to identify risk factors that can be targeted in prevention efforts for this population. Although several relationship-level risk factors for IPV have been identified in different-sex couples, research on SGM-AFAB is sparse and predominantly cross-sectional. The present study used seven waves of data from a longitudinal cohort study of SGM-AFAB youth (n = 463) to explore relationship factors (relationship quality, destructive conflict, and self- and partner-jealousy) as risk factors for perpetration and victimization of three types of IPV (physical, psychological, and coercive control). At each wave, participants reported on relationship factors and IPV for up to three romantic partners in the past 6 months. Multilevel models tested for associations between the relationship factors and IPV at three levels: between-persons, within-persons across time (wave), and within-persons across relationships. Relationship quality was associated with IPV mostly at the between-persons and within-persons (wave) levels. Couple conflict was associated with all IPV outcomes at all levels. Partner jealousy was more consistently associated with IPV victimization; participant jealousy was more consistently linked with IPV perpetration. These novel findings suggest that, within SGM individuals, IPV may be influenced by relationship quality, destructive conflict, and jealousy as they fluctuate within individuals from relationship to relationship and within individuals over time. As such, these relationship factors represent promising potential targets for interventions to reduce IPV among SGM-AFAB youth.

The influence of insecure attachment on undergraduates' jealousy: the mediating effect of self-differentiation.

Background: Jealousy is a complex emotion and can be healthy or pathological, depending on the intensity and the degree of control. Excessive jealousy was characterized by anxiety, anger, and alienation in the insecure attachment relationship. Objective: To explore how insecure attachment triggered this intense emotion, this study investigated the relationship between two insecure attachment dimensions and jealousy and explored the influence of self-differentiation on the relationship. Method: A total of 477 undergraduates participated in the study, and the Bringle self-report jealousy scale (BSJS), the relationship questionnaire (RQ), the intimate relationship experience questionnaire (ECR), and the revised edition of self-the differentiation questionnaire (DSR) were used. Result: The results showed that: (1) attachment anxiety had a significant positive predictive effect on jealousy, but attachment avoidance had no significant positive predictive effect; (2) self-differentiation partially mediated the relationship between attachment anxiety and jealousy, but it has no significant mediating effect between attachment avoidance and jealousy. Conclusion: The results suggest that attachment anxiety was correlated with jealousy because it strengthened the intensity of anxiety and anger toward their attachment figures and became out of control through a lower level of self-differentiation, which has important implications for clinical intervention.

A comparison of older and younger offenders with delusional jealousy.

We sought to determine whether or not there were differences in medical, criminological and legal factors between older and younger offenders with diagnoses of delusional jealousy by undertaking a retrospective case-file search of Australian legal databases. Our results demonstrate that older offenders were more likely to have comorbid dementia whereas younger offenders were more likely to have comorbid substance use and chronic psychotic conditions. A history of domestic violence frequently predated the index offence but we were unable to determine if this was due to psychosis or a pre-existing tendency for violence. Despite a common diagnosis, the older offenders were more likely to be made forensic patients rather than sentenced prisoners when compared with the younger offenders. Consequently, different factors might mediate the pathway to violence in older and younger people suffering from delusional jealousy and could be additional targets for clinical intervention.

Jealousy, sexism, and romantic love myths: the role of beliefs in online dating violence.

With the massification of the Internet and social networks, a new form of dating violence called cyber-violence has emerged, which involves behaviors of control, humiliation, intimidation and threats towards the partner or ex-partner. Using a non-probabilistic sample of 1,001 participants aged 18 to 25 years, the present study used an ex post facto, retrospective, cross-sectional, single-group design to analyze the joint effects that beliefs associated with dating violence such as romantic love myths, jealousy, and sexism have on the victimization and perpetration of cyber-violence. The results evidenced that jealousy is involved in both Cyber-victimization and Cyber-harassment perpetrated, while sexist beliefs are only involved in perpetration. In the discussion section, it is postulated that cyber-violence is a phenomenon that is more related to the probability of aggression, but not to the probability of being a victim. Finally, limitations and implications for future research are discussed.

Naïve Theories of Emotions: Why People Might (Not) Be Uncertain or in Conflict About Felt Emotions.

Beliefs about conflict and uncertainty over felt emotions-for Joy, Pride, Sadness, Jealousy and Envy events-were studied by means of Yes/No and Why questions. Each participant (N = 1,156) judged a typical antecedent for a single emotion-e.g., Jealousy: story protagonist SP sees his or her partner kiss someone. The Yes/No results showed that SP was frequently expected to experience both phenomena, the more so the greater the event impact (Yes range: 40-86%). Beliefs associated with Yes answers (BY) were categorized into 4 categories: (BY1) reason-emotion opposition-felt emotions are unreasonable, inadequate ways of reacting; (BY2) ambivalent emotions-e.g., joy and sadness; (BY3) unclear emotions; (BY4) other causes-e.g., focused on event implications, SP's personality. No conflict or uncertainty answers (BN; range 14-60%) mirrored BY categories: (BN1) no reason-emotion opposition, (BN2) no ambivalent emotions, (BN3) clear emotions, (BN4) other causes. Attributions and beliefs about causes did not generally differ by gender. As a collective entity, expressed beliefs were complex, focusing on one or more emotion component-e.g., appraisal, regulation, expression-as well as on emotion intensity, duration, and on self-concept issues. Overall, expressed beliefs seemed to imply a malleability theory of emotions, and emotion awareness. Results overall confirmed the hypotheses that conflict and uncertainty attributions are more likely for: unpleasant experiences; when emotions are norm-incongruent for the judged event; when mixed, ambivalent emotions are felt. The study confirms that people interpret emotion processes according to their lay theories.

Erectile Dysfunction, Suspicious Jealousy, and Partner-Directed Behaviors in Heterosexual Romantic Couples.

Erectile dysfunction (ED) can have negative consequences for men and their intimate partners. The purpose of the present research was to replicate and extend the results of previous studies concerning the connections that ED has with partner-directed behaviors using a sample of heterosexual romantic couples. Specifically, we used an actor-partner interdependence mediation model to examine whether the associations that ED had with men's mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injuries were mediated by suspicious jealousy, but not reactive jealousy. These associations were examined in 113 romantic couples, using men's self-reports, and partner-reports provided by their female partners. Results indicated that suspicious jealousy (but not reactive jealousy) mediated the associations that ED had with men's use of partner-directed behaviors, such that higher levels of ED were associated with men experiencing more suspicious jealousy, which, in turn, was associated with more cost-inflicting mate retention behaviors, benefit-provisioning mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injury. However, there were some discrepancies between the reports provided by men and women such that these associations emerged more consistently in the partner-reports provided by women than in the self-reports provided by men. Discussion addresses evolutionary implications of these findings, as well as limitations of this research and directions for research concerning ED.

Women's Romantic Jealousy Predicts Risky Appearance Enhancement Effort.

Human appearance enhancement effort has recently been considered from an evolutionary perspective as an adaptive and sexually dimorphic strategy for effective female intrasexual and intersexual competition. Most writing and research on the topic to date has focused on appearance enhancement as a means of mate attraction, with relatively less research examining its role in mate retention. The present study considered whether romantic jealousy, as a negative emotion experienced in response to perceived threat to a desired relationship, predicts costly and/or risky appearance enhancement independent of the closely related emotion of envy. In a sample of 189 undergraduate women, results showed that romantic jealousy and dispositional envy were positively correlated with one another. Results further demonstrated that romantic jealousy predicted women's positive attitude toward cosmetic surgery, willingness to use a one-week free tanning membership, willingness to use a risky diet pill, and intent on spending a greater proportion of their income on appearance enhancement, but not intended use of facial cosmetics. Results held independent of participants' dispositional envy, suggesting that romantic jealousy is a unique predictor of women's efforts at enhancing their physical appearance, which could extend into costly and physically risky mate retention efforts.

Relationship status and gender-related differences in response to infidelity.

Introduction: The sexual imagination hypothesis suggests that responses to a partner's infidelity emerge from the sociocultural factors that affect individuals' imagining of that occurrence irrespective of biological sex, including relationship status (i.e., the experience of a serious, committed relationship). Nevertheless, evolutionary psychological perspectives predict that responses to a partner's infidelity emerge from a sex-specific evolved innate mechanism. Methods: A lower 2D:4D digit ratio is associated with more robust responses to a partner's sexual infidelity. In this study, participants (660 males and 912 females) were requested to measure finger lengths, reactions to their partners' sexual and emotional infidelity, and relationship status. Results: A logistic regression and multiple regression analyses revealed that relationship status was uniquely associated with responses to a partner's sexual and emotional infidelity beyond the effects of sex and 2D:4D. Those in committed relationships were more upset or distressed over their partners' infidelity, particularly over sexual infidelity, than those not in committed relationships. Discussion: The results supported the sexual imagination hypothesis indirectly, while evolutionary psychological perspectives were met with skepticism. Our findings implied that sex differences in jealousy result from relationship status, and that responses to partners' infidelity are more alike than different.

The relationship between self-esteem and aggressive behavior among Chinese adolescents: A moderated chain mediation model.

This study aimed to examine the relationship between adolescent self-esteem and aggressive behavior. Specifically, a moderated chain mediation model was developed to investigate the mediating role of jealousy and self-control and the moderating role of gender. Data were collected from 652 Chinese adolescents who completed the Self-Esteem Scale, Self-Report Jealousy Scale, Self-Control Scale and Aggressive Behavior Questionnaire. Results showed that adolescent self-esteem may significantly negatively affect aggressive behavior by mediating with jealousy and self-control. Moreover, gender possibly moderates the serial mediating effect of jealousy and self-control between adolescent self-esteem and aggressive behavior. The results have important theoretical and practical implications in that these reveal the influencing factors of adolescent aggressive behavior and the pathways to reduce such behavior.

The relationship between parental role expectations and sibling jealousy: the mediating effect of first-born children's role cognition.

This study aimed to explore the relationship among parental role expectations, the firstborns' sibling jealousy and their role cognition. A sample of 190 two-family firstborns aged 3-7 years old and their parents from China participated in the study by using experimental methods, questionnaires, and interviews. The results showed: (1) Parental role expectations had a significant positive effect on firstborns' role cognition. (2) The dispositional sibling jealousy of the first-born children was positively correlated with their parents' role expectations. (3) Firstborns' role cognition mediated the relation between parental role expectations and episodic sibling jealousy completely. The first-born children were more inclined to perceive themselves as resource contender and experience the episodic sibling jealousy the greater the parental role expectations.
