Trajectories of relationship and sexual satisfaction over 2 years in the Covid-19 pandemic: A latent class analysis.

OBJECTIVE: Previous research on the impact of the Covid-19 pandemic on romantic relationships has mainly concentrated on short-term effects and average trends of change. This study aimed to explore different trajectories of relationship and sexual satisfaction from April 2020 to March 2022. METHOD: Including a cross-national sample of 2859 individuals, a latent class approach was applied to identify subgroups of sexual and relationship satisfaction trajectories. Participants' satisfaction levels, attachment style, psychological symptoms, life satisfaction, and living arrangements were taken into account. RESULTS: Three latent classes were identified for both relationship and sexual satisfaction: (1) a group with high satisfaction levels but a slightly declining trajectory, (2) a group with low satisfaction levels but an ascending trajectory, and (3) a fluctuating group. Living apart, having children, psychological symptoms, low life satisfaction, and avoidant attachment characterized the two groups with low or fluctuating trajectories. CONCLUSIONS: The findings suggest that there were different trajectories of relationship and sexual satisfaction during the pandemic, which can be predicted by individual dispositions. Even 2 years after the pandemic, its effects had not disappeared.

Online assessment of musical ability in 10 minutes: Development and validation of the Micro-PROMS.

We describe the development and validation of a test battery to assess musical ability that taps into a broad range of music perception skills and can be administered in 10 minutes or less. In Study 1, we derived four very brief versions from the Profile of Music Perception Skills (PROMS) and examined their properties in a sample of 280 participants. In Study 2 (N = 109), we administered the version retained from Study 1-termed Micro-PROMS-with the full-length PROMS, finding a short-to-long-form correlation of r = .72. In Study 3 (N = 198), we removed redundant trials and examined test-retest reliability as well as convergent, discriminant, and criterion validity. Results showed adequate internal consistency ( ω ¯ = .73) and test-retest reliability (ICC = .83). Findings supported convergent validity of the Micro-PROMS (r = .59 with the MET, p < .01) as well as discriminant validity with short-term and working memory (r ≲ .20). Criterion-related validity was evidenced by significant correlations of the Micro-PROMS with external indicators of musical proficiency ( r ¯ = .37, ps < .01), and with Gold-MSI General Musical Sophistication (r = .51, p<.01). In virtue of its brevity, psychometric qualities, and suitability for online administration, the battery fills a gap in the tools available to objectively assess musical ability.

The Emotion-to-Music Mapping Atlas (EMMA): A systematically organized online database of emotionally evocative music excerpts.

Selecting appropriate musical stimuli to induce specific emotions represents a recurring challenge in music and emotion research. Most existing stimuli have been categorized according to taxonomies derived from general emotion models (e.g., basic emotions, affective circumplex), have been rated for perceived emotions, and are rarely defined in terms of interrater agreement. To redress these limitations, we present research that served in the development of a new interactive online database, including an initial set of 364 music excerpts from three different genres (classical, pop, and hip/hop) that were rated for felt emotion using the Geneva Emotion Music Scale (GEMS), a music-specific emotion scale. The sample comprised 517 English- and German-speaking participants and each excerpt was rated by an average of 28.76 participants (SD = 7.99). Data analyses focused on research questions that are of particular relevance for musical database development, notably the number of raters required to obtain stable estimates of emotional effects of music and the adequacy of the GEMS as a tool for describing music-evoked emotions across three prominent music genres. Overall, our findings suggest that 10-20 raters are sufficient to obtain stable estimates of emotional effects of music excerpts in most cases, and that the GEMS shows promise as a valid and comprehensive annotation tool for music databases.

A prospective study of relationship and sexual satisfaction during the first year of the COVID-19 pandemic: The role of dispositional vulnerabilities and external stressors.

OBJECTIVE: The COVID-19 pandemic had a strong impact on many aspects of life, particularly social relationships. Although there is some evidence regarding short-term effects of the pandemic on cohabitating couples or individuals, it is unclear to what extent these effects persist over time and whether they also apply to noncohabitating individuals. The purpose of this study was to investigate changes in relationship and sexual satisfaction among both cohabitating and noncohabitating individuals during the first year of the pandemic and to examine the extent to which these changes could be accounted for by personal vulnerabilities, pandemic-related stressors, and their interaction. METHOD: We assessed relationship and sexual satisfaction longitudinally with a cross-national sample (N = 2859) that included five prospective measurement time points and analyzed the data with multilevel models. RESULTS: We observed a decrease in relationship satisfaction over the course of the study, especially among noncohabitants. Sexual satisfaction, in turn, conformed to a quadratic trend among noncohabitants while changing only minimally in cohabitating individuals. Of the individual vulnerabilities examined, attachment avoidance was the greatest risk factor for both relationship and sexual satisfaction. Among pandemic-related stressors, mobility restrictions had a negative impact into the relationship and sexual satisfaction of noncohabitating individuals. CONCLUSIONS: Although the pandemic generally showed negative effects on close relationships, these effects varied depending on the type of couple (cohabitants or noncohabitants), the component of relationship satisfaction (relationship satisfaction or sexual satisfaction), the time interval (curfew period or not), and also individual dispositions (especially attachment avoidance).

Salmonella Typhimurium DT 104 response to Lytic bacteriophage and Lactobionic acid on raw chicken breast.

Bacterial food poisoning cases due to Salmonella have been linked with a variety of poultry products. This study evaluated the effects of a Salmonella-specific Lytic bacteriophage and Lactobionic acid (LBA) on Salmonella Typhimurium DT 104 growth on raw chicken breast meat. Each chicken breast was randomly assigned to a treatment group (Control, DI water, phage 1%, phage 5%, LBA 10 mg/mL, LBA 20 mg/mL, and phage 5% + LBA 20 mg/mL) with four chicken breasts per group. Samples were inoculated with 106 CFU/mL of Salmonella and stored at 4 °C for 30 min. The inoculated chicken breasts were randomly assigned to different storage time (0 h, 1 h, 24 h, or 48 h). Both time and treatment showed significance reduction (P < 0.0001) of microbial growth. The weight loss was significantly different (P < 0.0001) between treatments. The LBA treatments were not effective when compared to the control group, but Lytic bacteriophage significantly reduced the amount of microbial growth.

Prosodic discrimination skills mediate the association between musical aptitude and vocal emotion recognition ability.

The current study tested the hypothesis that the association between musical ability and vocal emotion recognition skills is mediated by accuracy in prosody perception. Furthermore, it was investigated whether this association is primarily related to musical expertise, operationalized by long-term engagement in musical activities, or musical aptitude, operationalized by a test of musical perceptual ability. To this end, we conducted three studies: In Study 1 (N = 85) and Study 2 (N = 93), we developed and validated a new instrument for the assessment of prosodic discrimination ability. In Study 3 (N = 136), we examined whether the association between musical ability and vocal emotion recognition was mediated by prosodic discrimination ability. We found evidence for a full mediation, though only in relation to musical aptitude and not in relation to musical expertise. Taken together, these findings suggest that individuals with high musical aptitude have superior prosody perception skills, which in turn contribute to their vocal emotion recognition skills. Importantly, our results suggest that these benefits are not unique to musicians, but extend to non-musicians with high musical aptitude.

Associations between early childhood poverty and cognitive functioning throughout childhood and adolescence: A 14-year prospective longitudinal analysis of the Mauritius Child Health Project.

Associations between childhood poverty and cognitive outcomes have been examined from multiple perspectives. However, most evidence is based on cross-sectional data or longitudinal data covering only segments of the developmental process. Moreover, previous longitudinal research has mostly relied on data from Western nations, limiting insights of poverty dynamics in low- and middle-income countries. Here, we use data from the Mauritius Child Health Project, a large-scale prospective longitudinal study conducted in a then low-income country, to examine long-term associations between poverty in early childhood and cognitive performance across childhood and adolescence. Poverty-related factors were assessed at age 3 years and comprised indicators of psychosocial adversity and malnutrition. Cognitive functioning was assessed at ages 3 and 11 years by using standardized intelligence measures and at age 17 years by means of a computerized test battery. Using multiple hierarchical regression models, we found that chronic malnutrition and parental characteristics showed similar-sized, independent associations with initial cognitive functioning at age 3 as well as at age 11 years. For age 17 years, however, associations with early childhood risk factors vanished and instead, cognitive functioning was predicted by performance on prior cognitive assessments. Sex was also found to be a powerful predictor of cognitive trajectories, with boys improving and girls worsening over time, regardless of the level of their initial exposure to risk. The current findings indicate that, to prevent cognitive impairment, interventions tackling poverty and malnutrition should focus on the infancy period and be designed in a gender-sensitive way.

Relationship satisfaction in the early stages of the COVID-19 pandemic: A cross-national examination of situational, dispositional, and relationship factors.

The outbreak of the COVID-19 pandemic has had a large impact on various aspects of life, but questions about its effects on close relationships remain largely unanswered. In the present study, we examined perceived changes in relationship satisfaction at the beginning of the COVID-19 pandemic by using an international sample of 3,243 individuals from 67 different countries, mostly from Italy, the United States, the United Kingdom, Germany, Austria, and Switzerland. In April and May 2020, participants responded to an online survey that included questions about relationship satisfaction, their satisfaction before the pandemic, other relationship aspects (e.g., shared time), special circumstances (e.g., mobility restrictions), and enduring dispositions (e.g., insecure attachment). A decline in time shared with one's partner was most strongly associated with perceived decreases in relationship satisfaction, resulting in a different pattern of findings for cohabiting and non-cohabiting individuals. Among the most influential moderators were anxious and avoidant attachment. The findings offer insights into both aggravating and protecting factors in couples' responses to pandemic-related stressors.

Early Detection of Temperament Risk Factors: A Comparison of Clinically Referred and General Population Children.

Despite an extensive literature on associations between early childhood temperament and behavior problems, most of this evidence is based on general population samples. Hence, relatively little is known about the temperament characteristics of children who have been referred for in- or outpatient treatment of emotional and/or behavioral problems. Whether temperament-to-behavior problems identified in community samples would also be found in samples of clinically referred children is poorly understood. To redress this limitation, we compared temperament attributes of a predominantly preschool-aged sample of children referred for treatment of emotional and/or behavioral disorders (N = 87) with those from a similarly-aged general population sample (N = 85) by using the Integrative Child Temperament Screener (ICTS)-a new nine-item scale to identify clinically significant temperament attributes. Behavioral symptoms in the clinical sample were assessed through diagnostic interviews in combination with the Child Behavior Checklist (CBCL), which was also administered to the general population children. Compared with general population children, referred children exhibited substantially higher scores on all ICTS subscales except behavioral inhibition. Furthermore, areas under the curve analyses showed that discrimination of both groups based on CBCL scales could be improved by adding the ICTS. Overall, the findings fill a long-standing gap in evidence regarding temperament characteristics of children with serious emotional and/or behavioral symptoms and suggest a useful role for the ICTS in assessment, screening, and prevention.

Assessing musical ability quickly and objectively: development and validation of the Short-PROMS and the Mini-PROMS.

The study of musical ability has gained considerable traction across disciplines in recent years. In comparison, less effort has been invested in the development of sound measures of musical ability. To redress this gap, we conducted four studies to empirically validate two brief measures derived from the Profile of Music Perception Skills (PROMS)-an exceptionally inclusive battery of musical abilities that takes about 1 h to complete. In the Short-PROMS, test duration was reduced to less than half an hour by substantially reducing the number of trials per subtest. In the Mini-PROMS, the number of subtests was reduced to four, resulting in a battery that takes 15 min to complete. Both measures exhibited good internal consistency and retest reliability. Support for convergent, discriminant, and criterion validity was found across the studies. Additional strengths of the new instruments include their suitability for online administration and a feature called Modular PROMS, which offers researchers the possibility to request customized batteries that may include any combination of the subtests. The role of refining objective assessment instruments in research on music and the mind is discussed.
