Diversity in singlehood experiences: Testing an attachment theory model of sub-groups of singles.

OBJECTIVE: Relationship science has developed several theories to explain how and why people enter and maintain satisfying relationships. Less is known about why some people remain single, despite increasing rates of singlehood throughout the world. Using one of the most widely studied and robust theories-attachment theory-we aim to identify distinct sub-groups of singles and examine whether these sub-groups differ in their experience of singlehood and psychosocial outcomes. METHOD: Across two studies of single adults (Ns = 482 and 400), we used latent profile analysis (LPA) to identify distinct sub-groups of singles. RESULTS: Both studies revealed four distinct profiles consistent with attachment theory: (1) secure; (2) anxious; (3) avoidant; and (4) fearful-avoidant. Furthermore, the four sub-groups of singles differed in theoretically distinct ways in their experience of singlehood and on indicators of psychosocial well-being. CONCLUSIONS: These findings suggest that singles are a heterogeneous group of individuals that can be meaningfully differentiated based on individual differences in attachment security.

Affirmation-support, parental conflict, and mental health outcomes of transgender and gender diverse youth.

Background: Transgender and gender diverse young people (TGDY) are at higher risk of psychosocial distress relative to their cisgender counterparts. TGDY rely heavily on their parents to support their desired affirmation and to facilitate access to legal and medical affirmation. While it is well understood that parent conflict negatively impacts the well-being of children and young people, little is known about how parental conflict and parental affirmation support are related to TGDY well-being. Aims: The aim of the present study was to (1) explore affirmation experiences of TGDY, as reported by their parents, focusing in particular on parental support for affirmation and barriers to affirmation, and (2) test whether parental support and aspects of the coparenting relationship predicted TGDY mental health outcomes. Method: A sample of 63 parents (Mage = 45.71 years) of TGDY (aged 11 to 17 years) completed an online survey. Results: Almost 90% of the TGDY reported on had socially affirmed their gender, though fewer had taken steps to legally or medically affirm their gender. Parental support for affirmation was generally very high, and reported discrepancies between coparents were generally low; however, discrepancies were greatest for medical affirmation. Finally, parent support for affirmation was a strong predictor of lower TGDY depressive symptoms, though parental conflict did not predict TGDY mental health. Conclusion: Results highlight the important role of parental support for gender affirmation. Further research is needed to track the role of parental support and affirmation on TGDY well-being over time, and to ensure that such research is completed with more diverse samples.

Comparative mitochondrial genomics of sponge-dwelling snapping shrimps in the genus Synalpheus: Exploring differences between eusocial and non-eusocial species and insights into phylogenetic relationships in caridean shrimps.

The genus Synalpheus is a cosmopolitan clade of marine shrimps found in most tropical regions. Species in this genus exhibit a range of social organizations, including pair-forming, communal breeding, and eusociality, the latter only known to have evolved within this genus in the marine realm. This study examines the complete mitochondrial genomes of seven species of Synalpheus and explores differences between eusocial and non-eusocial species considering that eusociality has been shown before to affect the strength of purifying selection in mitochondrial protein coding genes. The AT-rich mitochondrial genomes of Synalpheus range from 15,421 bp to 15,782 bp in length and comprise, invariably, 13 protein-coding genes (PCGs), two ribosomal RNA genes, and 22 transfer RNA genes. A 648 bp to 994 bp long intergenic space is assumed to be the D-loop. Mitochondrial gene synteny is identical among the studied shrimps. No major differences occur between eusocial and non-eusocial species in nucleotide composition and codon usage profiles of PCGs and in the secondary structure of tRNA genes. Maximum likelihood phylogenetic analysis of the complete concatenated PCG complement of 90 species supports the monophyly of the genus Synalpheus and its family Alpheidae. Moreover, the monophyletic status of the caridean families Alvinocaridae, Atyidae, Thoridae, Lysmatidae, Palaemonidae, and Pandalidae within caridean shrimps are fully or highly supported by the analysis. We therefore conclude that mitochondrial genomes contain sufficient phylogenetic information to resolve relationships at high taxonomic levels within the Caridea. Our analysis of mitochondrial genomes in the genus Synalpheus contributes to the understanding of the coevolution between genomic architecture and sociality in caridean shrimps and other marine organisms.

Minority Stress and Psychological Outcomes in Sexual Minorities: The Role of Barriers to Accessing Services.

Lesbian, gay, and bisexual (LGB) individuals are at higher risk for poor mental health than their heterosexual counterparts, and these disparities are largely accounted for by minority stressors. Less is known about the mechanisms underlying associations between minority stress and mental health. In a sample of 592 LGB adults (Mage = 29.39), we tested a model in which minority stress (internalized stigma, stigma consciousness, and lived discrimination) was associated with poor mental health when mediated by stigma-related barriers to accessing psychological services. Structural equation modeling revealed that minority stressors predicted more barriers to service use which, in turn, predicted poorer mental health outcomes. Internalized stigma was also directly associated with poor mental health. Results suggest that links between minority stress and poorer mental health in LGB individuals are at least partly explained by stigma-related barriers to accessing services. Future research is needed to investigate methods which may ameliorate these barriers.

Minority Stress and Same-Sex Relationship Satisfaction: The Role of Concealment Motivation.

Most lesbian, gay, and bisexual (LGB) people want a stable, satisfying romantic relationship. Although many of the predictors of relationship outcomes are similar to those of heterosexual couples, same-sex couples face some additional challenges associated with minority stress that also impact upon relationship quality. Here, we investigate the association between minority stressors and relationship quality in a sample of 363 adults (M age = 30.37, SD = 10.78) currently in a same-sex romantic relationship. Internalized homophobia and difficulties accepting one's LGB identity were each negatively associated with relationship satisfaction via heightened concealment motivation. We also examined the protective role of identity affirmation on relationship quality, finding a direct positive relationship between the two variables. Minority stressors were negatively associated with couple relationship satisfaction via heightened concealment motivation. The finding that identity affirmation directly predicted increased couple satisfaction also highlights the important role of protective factors in same-sex couple relationships.

La mayoría de las personas lesbianas, gais y bisexuales (LGB) desean una relación amorosa estable y satisfactoria. Aunque muchos de los predictores de las complicaciones en las relaciones son similares a los de las parejas heterosexuales, las parejas del mismo sexo enfrentan algunas otras dificultades asociadas con el estrés de las minorías que también repercuten en la calidad de la relación. Aquí investigamos la asociación entre los factores desencadenantes de estrés en las minorías y la calidad de la relación en una muestra de 363 adultos (edad promedio = 30.37, desviación estándar = 10.78) que están actualmente en una relación amorosa del mismo sexo. La homofobia internalizada y las dificultades para aceptar la identidad LGB propia estuvieron asociadas negativamente con la satisfacción en la relación mediante un incremento de la motivación por la ocultación. También analizamos el papel protector que desempeña la afirmación de la identidad en la calidad de la relación y encontramos una relación positiva directa entre las dos variables. Los factores desencadentantes de estrés en las minorías estuvieron asociados negativamente con la satisfacción en la relación de pareja mediante un incremento de la motivación por la ocultación. El hallazgo de que la afirmación de la identidad predijo directamente una mayor satisfacción en la pareja también destaca el papel importante que desempeñan los factores protectores de las relaciones de pareja del mismo sexo.

The Effects of Mindfulness on Sexual Outcomes: The Role of Emotion Regulation.

Individuals higher in dispositional mindfulness, a quality of non-judgmental attention to the present moment, fare better than their less mindful counterparts on a wide range of psychological and interpersonal outcomes. However, remarkably little is known about the potential influence of dispositional mindfulness on sexual outcomes. Here we investigated whether dispositional mindfulness was associated with a range of sexual outcomes, including sexual satisfaction, sexual hyperactivation (heightened sexual desire and worry), sexual deactivation (suppression of sexual desire and behavior), and problematic pornography use. We also tested whether capacity for emotion regulation was the mechanism underlying the mindfulness-sexual outcome association. These hypotheses were tested in two samples: a sample of adults in a committed romantic relationship (N = 407) and a group of adults who were long-term single (N = 400). Across both samples, dispositional mindfulness predicted more adaptive sexual outcomes, and emotion regulation generally mediated these associations. Of particular importance, the positive effects of dispositional mindfulness on sexual outcomes appear to generalize across relationship statuses, with both partnered and long-term single individuals displaying a similar pattern of results. These findings highlight that high dispositional mindfulness may predict a range of positive sexual outcomes in both partnered and single individuals.

Integrating between-session interventions (homework) in therapy: the importance of the therapeutic relationship and cognitive case conceptualization.

Between-session interventions, or homework, are crucial to a range of psychological therapies, including cognitive behavior therapy (CBT). Therapeutic interventions often involve experiencing emotions and situations, or examining strongly held views about their problems, that clients can find distressing. Hence, the clinician faces a particular challenge in collaborating with the client to carry out these interventions between sessions. In this article, we convey how this process in CBT requires not only a consideration of the theoretically meaningful determinants of adherence behavior but also a sophisticated cognitive case conceptualization. Using case material, we illustrate the interplay between in-session design, planning, and review of between-session interventions and the conceptualization. We also include a distinction between generic elements of the therapeutic relationship and CBT-specific elements. The case material also attends to the person of the therapist, and his or her own cognitive and emotional reactions occurring throughout the process of discussing between-session interventions.

Reservations about the conclusions of the interdivisional (APA Divisions 12 & 29) task force on evidence-based therapy relationships: what do we know, what don't we know?

We offer a critical and constructive appraisal of the conclusions provided by the Interdivisional (American Psychological Association [APA] Divisions 12 & 29) Task Force on Evidence-Based Therapy Relationships. We highlight problems in overlapping terminology and definitions, as well as problems in the conduct of its meta-analyses (i.e., duplication of studies between reviews, inappropriate study inclusion, and use of measures of specific constructs for the calculation of effects for multiple relationship elements). On this basis, we express reservation about the conclusions offered by the APA Task Force. This special issue explores whether there are other therapeutic relationship elements that warrant consideration and further study. We were particularly interested in those elements that showed promise based on empirical or theoretical grounds, and in each article, we asked for an account of how the case formulation would guide the methods of adaptation for each individual client, and how the element would contribute to clinically relevant changes.
