Living well: Empirically developed structural equation model for healthy and effective self-regulation

The purpose of this study is to develop and empirically test a structural equation model (SEM) for healthy and effective self-regulation based on the propositions of self-determination theory (SDT). A cross-sectional data sample (N = 6,705) is used to test the model. The results of the SEM demonstrate good to excellent global fit indices (RMSEA = 0.06, SRMR = 0.04 CFI = 0.97, TLI/NNFI = 0.95) and excellent local fit indices (p < 0.001). It is acknowledged that longitudinal and experimental research designs will be necessary to infer causal effects. However, based on the strong theoretical and empirical grounding of the model, indications for causal effects are discussed beyond correlational relations. The local fit indices imply that autonomy of goals, intrinsic values orientation, mindfulness, and the newly integrated construct clarity about personal values positively affect psychological needs satisfaction and facets of subjective and psychological well-being. Additionally, they indicate that mindfulness and clarity about personal values have the greatest benefits on individual health, well-being, and effectiveness. These results are crucial as they emphasize the significant role of mindfulness in healthy and effective self-regulation. Furthermore, they put the spotlight on a rather new construct; clarity about personal values. By having transferred the knowledge base of SDT into an empirically derived model of healthy and effective self-regulation, this study provides well-grounded indications of how health, well-being, and effectiveness in individuals may be fostered. These indications offer new insights for theory building and practical interventions in domains like psychotherapy, healthcare, organizations, sports, and education.

Loneliness and problematic social networking sites use in young adults with poor vs. good sleep quality: The moderating role of gender

Despite the evidence of a relationship between loneliness, problematic social networking sites use (PSNSU), and sleep quality, associations between specific PSNSU symptoms and loneliness in individuals with poor vs. good sleep quality and possible gender differences have yet to be understood. We examined the relationships between loneliness and PSNSU symptoms (i.e., preference for online social interaction - POSI, mood regulation, deficient self-regulation, and negative outcomes), and possible moderating effects of gender for individuals with poor vs. good sleep quality. Seven hundred and sixty-three young adults completed an online survey including self-report measures of sleep quality, loneliness, and PSNSU symptoms. Individuals with poor sleep quality reported higher levels of loneliness and greater scores on all PSNSU domains than those with good sleep quality. Slope analyses revealed that in men vs. women with poor sleep quality, greater deficient self-regulation of social networking sites use was associated with lower levels of loneliness. Conversely, in men vs. women with good sleep quality, greater POSI was associated with higher levels of loneliness. Our findings showed that individuals with poor sleep quality are characterized by higher levels of loneliness and more severe PSNSU symptoms that may be the result of sleep disturbance-related metabolic, neural, and hormonal processes. Moreover, our results highlight gender differences for individuals with poor vs. good sleep quality which may help clarify the nature of the association between loneliness and PSNSU.

The role of social support in the experience of life with ischemic heart disease for socially disadvantaged patients: A qualitative study

OBJECTIVES

Ischemic heart disease (IHD) displays wide social inequalities that are often explained with reference to lifestyle factors. However, research indicates that social support may also play an important role in social inequality in IHD. This study aims to explore the role of social support in the experience of life with IHD for socially disadvantaged patients.

METHODS

The study was conducted as a critical hermeneutic qualitative study in Denmark between October 2018 and August 2019. Data consist of in-depth qualitative interviews with 30 socially disadvantaged patients with IHD.

RESULTS

The findings showed a notable difference between the participants who were engaged in close and supportive social relationships and those who were not. Life with IHD for those who lacked supportive relationships tended to be marked by feelings of chaos, powerlessness and meaninglessness. Contrarily, those who were engaged in supportive relationships received help to navigate their life with illness, reconcile with what had happened to them, feel empowered, and gain a sense of meaning in their life.Discussion: Social support from close social relationships appears to be crucial for socially disadvantaged ischemic heart patients, and should be encouraged and facilitated in healthcare and interventions targeting this patient group.

The nomological network of drinker identity: A scoping review

BACKGROUND

Despite the growing interest in the construct of drinker identity and empirical evidence for its role in drinking behavior, there is a paucity of papers that evaluate and integrate the results of studies on drinker identity, leaving a gap in our knowledge of the importance of the drinker identity construct. The current paper addresses this gap by reviewing and integrating the results of the studies of drinker identity.

METHODS

The scoping review identified, retrieved, and evaluated the existing literature regarding drinker identity. English language studies from EBSCOHost, PubMed, ScienceDirect, and Scopus databases were reviewed. Studies were included in the review if they were data-based studies or theoretical publications with drinker identity as the primary topic published in peer-reviewed journals. Studies were reviewed and coded based on their reported methodology and findings and codes were used to integrate and present findings.

RESULTS

This review advances this line of research in four ways. First, the operationalization of drinker identity is evaluated by examining the theoretical frameworks defining the construct. Second, the conceptualization and measurement of drinker identity is assessed, with suggestions for future measurement research. Third, an integrated framework of predictors, outcomes, moderators, and mediators is presented. Finally, the research gaps, future recommendations, and clinical implications are discussed.

CONCLUSIONS

There is a need for continued research, specifically research which aims to standardize and improve measurement of drinker identity, considers longitudinal and developmental processes, and broadens the research samples and settings.

Transcranial focused ultrasound modulates the emergence of learned helplessness via midline theta modification

BACKGROUND

Helplessness and hopelessness are states closely related to depressive disorders. They ensue following the anticipated absence of valid behavioral options to alleviate an aversive state. One neural structure involved in the detection of such options, is the cingulate cortex (CC), which conveys the evaluation of behavior against the value of its outcome. Accordingly, CC-related EEG measures are thought to correlate to feedback evaluation but also to anxious and conflict-related states, signaling the need for further adaptation to current requirements. Against this background, this study investigated the role of CC functioning in the emergence and prevention of helpless/hopeless states by applying low-intensity transcranial focused ultrasound (litFUS) neuromodulation prior to a learned helplessness task.

METHOD

In a randomized controlled double blind experimental setup with 55 participants, litFUS was used to inhibit the right lateral prefrontal cortex (lPFC), a region closely connected to CC modulation. Participants were instructed to play 8 games of chess against a computer that was unbeatable to them, while an EEG was recorded. Theta oscillation in midline electrodes, playing performance and self-rate measures on cognitive, affective and physiological parameters were assessed.

RESULTS

The results show a considerable influence of litFUS neuromodulation of the lPFC on midline theta activity (Fz and Pz electrode position) which in turn correlated to several psychological variables including self-report data on emotion, cognition, and arousal as well as behavioral measures (playing performance).

LIMITATIONS

Due to the small sample size and sample characteristics, results cannot be generalized to the field of clinical application. A replication of results in larger samples and in context of other sonication parameters is needed to increase the robustness of results and to maximize the efficacy of litFUS application.

CONCLUSIONS

We conclude that the development of learned helplessness/hopelessness could be positively influenced in its course by litFUS neuromodulation of the right lPFC. In line with previous results, especially the posterior midline electrode Pz seems to be an interesting target for further research in this field as theta activity at this electrode is correlated to control perception and motivated behavior. To our knowledge, this is the first study to use neuromodulation to monitor and manipulate the development of helplessness in the laboratory.

Emotional and social loneliness and their unique links with social isolation, depression and anxiety

BACKGROUND

Loneliness and social isolation are known to be associated with depression, general anxiety, and social anxiety. However, knowledge on the overlapping and unique features of these relationships, while differentiating between social loneliness (perceived absence of an acceptable social network) and emotional loneliness (perceived absence of close connections), is lacking.

METHODS

We constructed a network analysis to examine the relationships between self-reported social loneliness, emotional loneliness, social isolation, depression, general anxiety and social anxiety in a large sample of university students (N = 7314, 67.4 % female, range 16.3-75.8 years, M_age = 23.9, SD_age = 5.7). Hierarchical regression analyses were used to examine whether depression, general anxiety and social anxiety moderated the relationship between social isolation and loneliness types. As comorbidity between anxiety and depression is high, the role of anxiety as a moderator in the relationship between depression and loneliness types was also examined.

RESULTS

The network analysis showed that social loneliness was most strongly explained by social isolation, whereas emotional loneliness was most strongly explained by social anxiety and depression. General anxiety was solely related to loneliness through depression. The regression analyses showed that general and social anxiety and depression did not moderate the relationship between social isolation and loneliness types.

LIMITATIONS

Differences found between loneliness types may be influenced by a methodological artifact of the DJGLS.

CONCLUSIONS

These findings highlight the importance of social anxiety over general anxiety in relation to loneliness. Also, it showed unique relationships for social- and emotional loneliness with psycho-social variables, which has important implications for research- and clinical settings.

Having less means wanting more: Children hold an intuitive economic theory of diminishing marginal utility

Judgments surrounding resource acquisition and valuation are ubiquitous in daily life. How do humans decide what something is worth to themselves or someone else? One important cue to value is that of resource quantity. As described by economists, the principle of diminishing marginal utility (DMU) holds that as resource abundance increases, the value placed on each unit decreases; likewise, when resources become more scarce, the value placed on each unit rises. While prior research suggests that adults make judgments that align with this concept, it is unclear whether children do so. In Study 1 (n = 104), children (ages 5 through 8) were presented with scenarios involving losses or gains to others' resources and predicted the actions and emotions of the individuals involved. Participants made decisions that aligned with DMU, e.g., expecting individuals with fewer resources to expend more effort for an additional resource than individuals with greater resources. In Study 2 (n = 104), children incorporated information about preferences when inferring others' resource valuations, showing how quantity and preference are both included in children's inferences about others' utility. Our results indicate the early emergence of an intuitive economic theory that aligns with an important economic principle. Long before formal learning on this topic, children integrate quantity and preference information to sensibly predict others' resource valuations, with implications for economic decision-making, social preferences, and judgments of partner quality across the lifespan.

Family First: Evidence of Consistency and Variation in the Value of Family Versus Personal Happiness Across 49 Different Cultures

People care about their own well-being and about the well-being of their families. It is currently, however, unknown how much people tend to value their own versus their family’s well-being. A recent study documented that people value family happiness over personal happiness across four cultures. In this study, we sought to replicate this finding across a larger sample size ( N = 12,819) and a greater number of countries ( N = 49). We found that the strength of the idealization of family over personal happiness preference was small (average Cohen’s ds = .20, range −.02 to.48), but present in 98% of the studied countries, with statistical significance in 73% to 75%, and variance across countries <2%. We also found that the size of this effect did vary somewhat across cultural contexts. In Latin American cultures highest on relational mobility, the idealization of family over personal happiness was very small (average Cohen’s ds for Latin America = .15 and .18), while in Confucian Asia cultures lowest on relational mobility, this effect was closer to medium ( ds > .40 and .30). Importantly, we did not find strong support for traditional theories in cross-cultural psychology that associate collectivism with greater prioritization of the family versus the individual; country-level individualism–collectivism was not associated with variation in the idealization of family versus individual happiness. Our findings indicate that no matter how much various populists abuse the argument of “protecting family life” to disrupt emancipation, family happiness seems to be a pan-culturally phenomenon. Family well-being is a key ingredient of social fabric across the world, and should be acknowledged by psychology and well-being researchers and by progressive movements too.

Anodal stimulation of inhibitory control and craving in satiated restrained eaters

OBJECTIVES

Eating and weight disorders are severe and complex clinical conditions which, among other behaviors, include (attempts at) restrained eating, food avoidance, following dietary rules, and overeating. Comparable to women with obesity, restrained eaters (RE) without formal eating disorder diagnosis are worse at inhibiting their motor responses than unrestrained eaters (URE). According to neuroimaging studies, the right inferior frontal gyrus (rIFG) is involved in inhibitory control which, in turn, could be improved by neuromodulation such as anodal transcranial direct current stimulation (tDCS) across rIFG.

METHODS

This double-blind sham-controlled cross-over study was conducted after a standardized breakfast. Normal-weight female RE und URE performed a stop-signal task (SST) with food and non-food stimuli during sham or anodal tDCS. Food craving, hunger, and satiety were self-reported before and after tDCS. We employed a mixed between-subjects (group: RE vs. URE) and within-subjects factorial design (tDCS: anodal tDCS vs. sham; stimuli: food vs. control pictures).

RESULTS

Breakfast consumption was comparable for RE and URE, as well as craving, hunger, and thirst. Regarding inhibitory control, a significant two-way interaction between group and tDCS ermerged: RE had longer stop-signal reaction times (SSRTs) during sham tDCS, but they improved to the level of URE by application of anodal tDCS.

DISCUSSION

Results replicated an inhibitory control deficit in RE with longer SSRTs compared to URE without stimulation. During anodal tDCS to the rIFG, reduced SSRTs in RE indicated an improvement in inhibitory control. The findings suggest a specificity of rIFG stimulation in at-risk groups with regards to inhibitory control irrespective of craving.
