Cross-lagged panel analysis of the relationship between social networking sites use (SNSU) and sleep problems among university students.

BACKGROUND: Sleep remains a cornerstone for sociopsychological well-being, but it is in decline, especially among today's youth. Simultaneously, engagement with social media is escalating. Research has identified a link between social networking sites use and sleep problems; however, the nature and direction of the relations remain obscure. Therefore, it is imperative to pursue longitudinal research to elucidate this correlation and guide suitable intervention practices. The present study aimed to examine the reciprocal relationship between social networking sites use and sleep problems. METHODS: By adopting a three-stage cross-lagged design across four time points, assessment results from 194 university students were gathered at four-week intervals. RESULTS: The findings indicate that (1) Social networking sites use was significantly greater in females than in males at all four time points, while sleep problems were significantly greater in females than in males at Time 3 and Time 4. (2) Sleep problems at the second time point serve as a positive predictor of subsequent social networking sites use at the third time point. (3) Social networking sites use at the initial time point could marginally significantly predict sleep problems at the fourth time point. CONCLUSIONS: This study elucidates the dynamic relationship between social networking sites use and sleep problems across an academic term, suggesting the need for temporally tailored interventions.

Harsh parenting and child conduct and emotional problems: parent- and child-effects in the 2004 Pelotas Birth Cohort.

In high-income countries, links between harsh and abusive parenting and child conduct and emotional problems are well-documented. However, less is known about these relationships in low- and middle-income countries, where harsh parenting may be more widely accepted and higher rates of conduct or emotional problems may exist which could influence the strength of these associations. We sought to investigate these relationships in a large population-based, prospective longitudinal study from Brazil, which also allowed us to test for sex differences. Using data from the 2004 Pelotas Birth Cohort Study (N = 4231) at ages 6 and 11 years, we applied cross-lagged path analysis to examine the relationships between harsh parenting (Conflict Tactics Scale Parent-Child version), and child conduct and emotional problems (Strengths and Difficulties Questionnaire). We found reciprocal relationships between harsh parenting and child conduct problems, with harsh parenting at age 6 predicting child conduct problems at age 11, and vice versa, even after adjusting for initial levels of conduct problems and harsh parenting, respectively. For child emotional problems, only unidirectional effects were found, with harsh parenting at age 6 predicting child emotional problems at age 11, after adjusting for initial levels of emotional problems, but not vice versa. No significant sex differences were observed in these relationships. These observations based on a middle-income country birth cohort highlight the potential universality of detrimental effects of harsh parenting on child conduct and emotional problems and affirm the importance of addressing parent- and child-effects in preventive and treatment interventions, especially those targeting conduct problems.

Longitudinal relations between abusive supervision, subordinates' emotional exhaustion, and job neglect among Pakistani Nurses: The moderating role of self-compassion.

The main purpose of this study was to investigate reciprocal relationships between abusive supervision, subordinates' emotional exhaustion, and job neglect, and to examine the mediating role of emotional exhaustion in the cross-lagged relationship between abusive supervision and job neglect. Besides, we tested the moderating role of self-compassion in the cross-lagged relationship between abusive supervision and emotional exhaustion. We applied a two-wave cross-lagged panel design with a time lag of six months. Participants were 331 staff nurses of public sector hospitals in Islamabad, Pakistan. Data were collected using a self-report questionnaire at two points in time. Longitudinal structural equation modeling (SEM) was used to compare nested models. Results of cross-lagged SEM analyses supported the posited reciprocal model, indicating that abusive supervision, emotional exhaustion, and job neglect are mutually related. Results of mediation analysis showed that emotional exhaustion partially mediates the cross-lagged relationship between abusive supervision and job neglect. Further, we found that self-compassion attenuates the positive cross-lagged effect of abusive supervision on emotional exhaustion, and the indirect effect of abusive supervision on job neglect was weaker at higher levels of self-compassion. Our findings suggest that subordinates may find themselves in abusive relationships, in part, because their own behavioral responses to abuse can reinforce abusive supervision. Moreover, we identified the stress-buffering effect of self-compassion on emotional exhaustion.

Association between eating frequency and eating behaviours related to appetite from 4 to 7 years of age: Findings from the population-based birth cohort generation XXI.

The examination of specific characteristics of eating habits in childhood and its influence on eating behaviours is needed to better understand the establishment of appetite-related eating behaviours. This study aimed to assess the association between eating frequency (EF) (main meals vs. snacks) at 4 and 7y and problematic eating behaviours and appetite-related eating behaviours at 7y. The analysis included 1359 children from the birth cohort Generation XXI who provided 3-day food diaries, at both ages, and complete information on the Child Eating Behaviour Questionnaire, at 7y. Problematic eating behaviours were assessed using parental perception of child's poor eating (including not eating enough, eating too slow or overeating) at both ages. A time-of-day approach was used to distinguish main meals from snacks. A cross-lagged analysis was performed to check the direction of the association between EF and parental concerns regarding problematic eating behaviours. Associations between EF and appetite-related eating behaviours were evaluated through linear regression models. Between 4 and 7y a moderate tracking of EF was described as well as a strong tracking of parental concerns. We found a bidirectional relationship between EF and parental concerns. Prospectively, a higher frequency of snacks at 4y was independently associated with higher scores in 'Desire to Drink' at 7y (ß = 0.051, 95%CI:0.009; 0.093). At 7y, a higher EF had a positive association with 'Satiety Responsiveness' but an inverse association with 'Enjoyment of Food'. A higher number of main meals had a positive association with 'Enjoyment of Food' and 'Food Responsiveness'. In conclusion, children who had more eating occasions seem to have more food-avoidance behaviours, traits that might protect these children from gaining excessive weight.

[Impact of Intimate Partner Violence on Child's Cognitive Development - Results from the Evaluation of the Home Visiting Program "Pro Kind"]. / Einfluss von Partnergewalt auf die kindliche kognitive Entwicklung ­ Ergebnisse der Begleitforschung zum Hausbesuchsprogramm "Pro Kind".

Impact of Intimate Partner Violence on Child's Cognitive Development - Results from the Evaluation of the Home Visiting Program "Pro Kind" Intimate partner violence (IVP) is a socially relevant problem area of high prevalence. Direct or indirect IVP leads to well documented problems in child socioemotional development. Longitudinal studies on influences of IVP on child's cognitive development are rare. The present study adds to close this gap. We analyze data from n = 535 families living under psychosocial risk conditions. All families took part in the evaluation of the home visiting program "Pro Kind". We administered one item of a parent questionnaire to assess the occurrence of IVP. The child's cognitive development is assessed at the ages of 6, 12, and 24 months of age with the Bayley Scales-II. We test the hypothesis that IVP to the mother causally affects early cognitive development of children in a structural equation model with Cross-Lagged-Panel design. The results show a causal influence of IVP on child's cognitive development during the period from t3 (12 months of child's age) to t4 (24 months of child's age). The explanatory power of results is limited by methodological problems, e. g. the operationalization of IVP with only one item and a high panel mortality. Implications for early prevention and intervention of IVP are derived.

Modeling Longitudinal Relationships Between Habit and Physical Activity: Two Cross-Lagged Panel Design Studies in Older Adults.

These longitudinal studies in older adults targeted mediated relationships between habit and physical activity (PA). In The Netherlands two independent studies were conducted among 1976 (Study 1: Mage = 63.63, SD = 8.66, 30% functional limitations) and 2140 (Study 2: Mage = 62.75, SD = 8.57, 45% functional limitations) adults aged 50 years or older. Cross-lagged panel designs were applied to examine whether habit mediates the relationship between prior and later PA and whether PA simultaneously mediates the relationship between prior and later habit. Data on habit and PA were collected by means of questionnaires at baseline (t0) and at 6 (t1) and 12 (t2) months after baseline measurement. Results of structural equation modeling analyses were not unambiguous. Indications for the existence of both hypothesized mediation effects were found, but no clear, unequivocal pattern appeared. Somewhat more support was found for the PA-habit-PA path than for the habit-PA-habit path. More research is needed to draw more definitive conclusions.

Time-lagged relationships between leadership behaviors and psychological distress after a workplace terrorist attack.

PURPOSE: The impact of leadership practices on employee health may be especially evident after extreme events that have physical, psychological, or material consequences for the members of an organization. In this prospective study, we aimed to examine the association between leadership behavior and psychological distress in employees who had experienced a workplace terror attack. METHODS: Ten and 22 months after the 2011 Oslo bombing attack targeting their workplace, ministerial employees (n = 2272) responded to a questionnaire assessing fair, empowering, supportive, and laissez-faire leadership, as well as psychological distress. Cross-sectional and time-lagged associations between the constructs were tested using structural equation modeling. RESULTS: Cross-sectionally, higher levels of supportive leadership were associated with lower levels of psychological distress. Longitudinally, negative relationships were found between psychological distress and subsequent ratings of fair and empowering leadership. CONCLUSIONS: Supportive leadership was associated with employees' psychological health after trauma, but seems not to have long-term effects on subsequent psychological distress. Rather, psychological distress may lead the employees to perceive their leaders as more negative across time.

Deprivation as a fundamental cause of morbidity and reduced life expectancy: an observational study using German statutory health insurance data.

Across all developed countries, there is a steep life expectancy gradient with respect to deprivation. This paper provides a theoretical underpinning for this gradient in line with the Grossman model, indicating that deprivation affects morbidity and, consequently, life expectancy in three ways: directly from deprivation to morbidity, and indirectly through lower income and a trade-off between investments in health and social status. Using rich German claims data covering 6.3 million insured people over four years, this paper illustrates that deprivation increases morbidity and reduces life expectancy. It was estimated that highly deprived individuals had approximately two more chronic diseases and a life expectancy reduced by 15 years compared to the least deprived individuals. This mechanism of deprivation is identified as fundamental, as deprived people remain trapped in their social status, and this status results in health investment decisions that affect long-term morbidity. However, in the German setting, the income and investment paths of the effects of deprivation were of minor relevance due to the broad national coverage of its SHI system. The most important aspects of deprivation were direct effects on morbidity, which accumulate over the lifespan. In this respect, personal aspects, such as social status, were found to be three times more important than spatial aspects, such as area deprivation.

Longitudinal relationships between depressive symptoms and cognitive function after stroke: A cross-lagged panel design.

OBJECTIVE: Stroke is a leading cause of mortality and disability. This study aimed to investigate the temporal and directional relationships between post-stroke depressive symptoms and cognitive impairment using a cross-lagged panel design. Depressive symptoms and cognitive impairment are two common post-stroke complications. However, the precise underlying mechanism remains unclear despite their close relationship. Therefore, elucidating the causal relationship between these two issues is of great clinical significance for improving the poor prognosis of stroke. METHODS: This study employed a hospital-based multicenter prospective cohort design. A total of 610 patients with ischemic stroke were eligible. Depressive symptoms (measured using the seventeen-item Hamilton Rating Scale for Depression) and cognitive function (measured using the Montreal Cognitive Assessment) were assessed at baseline and the 12-month follow-up. Spearman's correlation was used to examine the correlation between cognitive function and depressive symptoms. Additionally, a cross-lagged panel analysis was employed to elucidate the causal relationship between these factors after adjusting for potential covariates. RESULTS: The results of a four-iteration cross-lagged panel analysis substantiated a bidirectional relationship between post-stroke depressive symptoms and cognitive function over time. Specifically, higher scores for early depressive symptoms were associated with lower scores for later cognitive function; additionally, higher baseline cognitive function scores were associated with lower depressive symptom scores at a later point. CONCLUSION: This study establishes a reciprocally causal long-term relationship between depressive symptoms and cognitive function after an ischemic stroke. Therefore, interventions aimed at improving cognitive function and ameliorating depressive symptoms may positively affect both cognition and mood. TRIAL REGISTRATION: ChiCTR-ROC-17013993.

The longitudinal relationship between bullying victimization and depressive symptoms for middle school students: A cross-lagged panel network analysis.

BACKGROUND: Previous research about the relationship between bullying victimization and adolescent depressive symptoms was mostly based on latent variable modeling. This study, instead, applied item-level analysis to explore the cross-sectional relationship and longitudinal development between bullying victimization and adolescent depressive symptoms with network models. METHODS: This study used Olweus Bully/Victim Questionnaire and Children's Depression Inventory to collect data. A total of 1911 middle school students (55.2 % female; Mage = 12.98 ± 0.60 at T1) completed measures on four occasions at 6-month intervals. Nine network analysis models were employed to better understand the relationship between variables. RESULTS: (1) "Being threatened or intimidated" was the most influential bullying behavior within bullying victimization items; (2) "being excluded", "being spoken ill of" and "negative mood" were the bridge items between bullying victimization and adolescent depressive symptoms; (3) the most influential bullying victimization item on adolescent depressive symptoms was "being robbed or blackmailed" for short-term development and "being excluded" for long-term development. While the most affected depressive symptom by bullying victimization was "anhedonia" for short-term development and "negative mood" for long-term development. LIMITATIONS: Self-report measure is adopted for all variables in the study, and there may be some deviation. Due to the questionnaires, the items of bullying behaviors and depressive symptoms included in the network analysis are limited. CONCLUSIONS: From the item level, this study found more specific relationships between bullying victimization and adolescent depressive symptoms. These findings highlight depressed mood and anhedonia are depressive symptoms that should be more paid attention to in clinical intervention for bullying victims.

A Longitudinal Study of the Impact of Personal and Professional Resources on Nurses' Work Engagement: A Comparison of Early-Career and Mid-Later-Career Nurses.

To predict and ensure a healthy and high-performing nursing workforce, it is necessary to identify the antecedents that promote work engagement, especially among early-career nurses. To date no study has focused on this. This longitudinal survey, administered to 1204 nurses working in seven general hospitals with 200 or more beds in four prefectures in Japan at two different times in 2019, aims to examine the causal relationship between the personal and professional resources for nurses to work vigorously (PPR-N) and work engagement among nurses in the early stages of their careers, considering time as a key mediating factor. The analysis of structural equation modeling using the cross-lagged effect model supported that PPR-N had significant and positive effects on work engagement after 3 months among early-career nurses with less than 10 years of nursing experience. The PPR-N is a reliable antecedent of work engagement, which is typical of early-career nurses. These results may be provided guidance for managers in overseeing the work environment to ensure a thriving sustainable nursing workforce.

The relevance of pharmacological neuroenhancement for stress and resilience-A multistudy report.

Background: Pharmacological neuroenhancement (PNE) is discussed as coping strategy in academic and work-related contexts. Depending on the definition of PNE and sample population, different prevalence rates for various groups have been reported. In the three parts of the study, prevalence rates for work and student populations in Germany are detected and the reasons for PNE and possible causal associations between PNE, stress and resilience are investigated. Methods: In part 1 of the study, 152 occupational physicians (OPs) were surveyed about prevalence rates and reasons for PNE. In part 2 of the study, 1,077 German students reported on their PNE behavior. 704 students were then longitudinally considered to draw conclusions on causal associations between PNE, stress, and resilience. Results: The OPs' estimated prevalence rate of 10.9% in a working population is higher than the prevalence rate of 5.4% for prescription and illicit substances found in the student sample in part 2 of the study. The reason suspected by OPs to be most important for PNE with prescription drugs were performance pressure and long working hours. Using soft enhancers, such as caffeine, is most common with a prevalence rate of 76.8% in the student sample. Stress predicts a higher (ß = 0.179, p < 0.001) and resilience a lower use of PNE (ß = -0.13, p = 0.001). Resilience predicts a lower (ß = -0.35, p < 0.001) and PNE a higher level of stress (ß = 0.11, p < 0.001). Conclusion: OPs suspect a prevalence rate of 10.9% among the working population, while we found a prevalence rate of 5.4% among students. Caffeine is the most used substance for PNE, while the use of prescription and illicit substances remains low. Higher levels of stress and lower levels of resilience result in a higher use of PNE. Universities should therefore include the promotion of resilience and methods for dealing with study stress in health programs to reduce PNE.

Associations Among the Big Five Personality Traits, Maladaptive Cognitions, and Internet Addiction Across Three Time Measurements in 3 Months During the COVID-19 Pandemic.

The present study examined the longitudinal association among the Big Five personality traits, maladaptive cognitions, and Internet addiction during the COVID-19 pandemic. A total of 481 Chinese university students (247 men; mean age = 20.31 years) were surveyed three times (interval of 1 month) by using the Chinese version of the Big Five Personality Traits Scale, Maladaptive Cognitions Scale, and Internet Addiction Scale. The results of a cross-lagged panel analysis highlighted that (i) extraversion, agreeableness, conscientiousness, and openness were negatively associated with maladaptive cognitions and Internet addiction, whereas neuroticism was found to be positively associated with maladaptive cognitions and Internet addiction across time; (ii) associations among the Big Five personality traits, maladaptive cognitions, and Internet addiction were dynamic and bidirectional; and (iii) maladaptive cognitions played mediating roles in extraversion, agreeableness, conscientiousness, openness, and Internet addiction across time. The Big Five personality traits, maladaptive cognitions, and Internet addiction predicted each other across time, and maladaptive cognitions were likely to be the key mediating factor in the associations between the Big Five personality traits and Internet addiction, which supported and expanded the Davis' cognitive-behavioral model.

Cross-lagged longitudinal analysis of pain intensity and sleep disturbance.

BACKGROUND: There is substantial evidence that pain intensity and sleep are related, with findings generally suggesting more support for the influence of sleep on pain intensity than vice versa. However, the strength and direction of the relationship has been found to vary among different populations, with few studies in individuals with chronic physical disabilities. OBJECTIVE: Examine the directionality of the sleep and pain relationship in individuals with chronic physical disabilities. METHODS: Cross-lagged effects models were generated using data from a longitudinal observational survey study of individuals (N = 1660) with multiple sclerosis (MS), muscular dystrophy (MD), post-polio syndrome (PPS), and spinal cord injury (SCI). Models evaluated the correlational effects of sleep disturbance and pain intensity, as well as the cross-lagged effects of sleep disturbance to pain intensity and vice versa. RESULTS: The effects of pain on sleep were stronger than sleep on pain, although the magnitude of the effects were both relatively weak. Analyses within individual samples were consistent with the overall sample results for MS, MD, and PPS. In the SCI sample the magnitude and direction of the cross-lagged model paths were more variable than in the other samples. CONCLUSIONS: The relationship between pain intensity and sleep disturbance appears bi-directional, but the effects are small in a sample of individuals with long-term disabilities. The temporal effects of pain on sleep disturbance appear stronger than the effects of sleep disturbance on pain intensity. Future research is needed to better understand this relationship in the context of pain and/or sleep disturbance treatments.

Temporal Precedence of Physical Literacy and Basic Psychological Needs Satisfaction: A Cross-Lagged Longitudinal Analysis of University Students.

: Purpose: Building on self-determination theory and extending research in the physical education context in terms of basic psychological needs satisfaction and physical literacy, this study examines the bidirectional effects of basic psychological needs satisfaction and physical literacy over time in a university physical literacy context. METHOD: Using a two-wave design, data were collected twice with an 18-week time lag from a sample of 549 university students. Utilizing full cross-lagged analyses, we examined the bidirectional effects between basic psychological needs satisfaction and physical literacy. RESULTS: The results provide support for a positive relationship between physical literacy (Time 1) and basic psychological needs satisfaction (Time 2), but we cannot reject the possibility of a bidirectional relation, supporting our expectations. CONCLUSION: Overall, the study highlights the importance of a reciprocal relationship between physical literacy and basic psychological needs satisfaction.

Converging Development of English as Foreign Language Listening and Reading Comprehension Skills in German Upper Secondary Schools.

Receptive skills in English as a second language are important for students on the verge of entering higher education as this student group (aged 17-19) is expected to apply English regularly in their later life. Previous research in this age group in Germany already implied an increasing overlap between both skills in this age group, although robustness of this effect across student groups with different learning experiences was not tested. We used language assessment data collected from upper secondary schools (i.e., from 17 to 19-year-old students) in Germany to compare correlations at the beginning and the end of upper secondary education in groups of students from (1) language-related versus non-language-related study profiles and (2) from students with frequent versus less frequent self-reported English-language out-of-school learning activities. In all of these groups, correlations were increasing, indicating converging skills in upper secondary education. The results are discussed in terms of implications for current theories of language research.

Cyberbullying: relationship with developmental variables and cyber victimization.

BACKGROUND AND OBJECTIVE: Cyberbullying is increasingly turning into a significant problem for children and adolescents due to its adverse psychological and academic outcomes. In the present study, the protective and risk factors for cyberbullying has been investigated. One of the aims of the study was to examine the relationship between peer relations, negative emotion regulation strategies, and cyberbullying. The successful identity development process is thought to influence both cyberbullying behaviors as well as adolescents' peer relations and emotion regulation. Also, cyber victimization is seen as a risk factor for cyberbullying. The second aim of the study is to investigate the causal relationship between cyber victimization and cyberbullying. METHOD: The study is a descriptive research in which both cross-sectional and longitudinal data were used. In the cross-sectional part of the study, 1,151 adolescents have participated, and the data of the second wave was obtained from 322 of them four months later. Data were analyzed through structural equation modeling (SEM) and hierarchical regression analyses. RESULTS AND CONCLUSION: According to the results of SEM, good peer relations predicted less cyberbullying. The expressive repression explained the cyberbullying through peer relationships. For identity development, contrary to expectations, commitment dimension of identity seemed to be positively related to more cyberbullying and so did higher reconsideration of commitment. Cross-lagged panel analyses revealed that Time 1 cyber victimization predicted Time 2 cyberbullying. Given the pattern of cross-lagged relationships, it was tentatively inferred that cyber victimization was the temporal precursor to cyberbullying. The results of the study have implications for the prevention of cyberbullying.

The Interplay of Students' School Engagement, School Self-Concept and Motivational Relations during Adolescence.

Existing literature evidences the association between adolescents' school self-concept and engagement, both concepts being related to students' perception of teachers and peers as motivators. However, few longitudinal studies explore the interplay of these factors. The present study aims to close this gap, applying latent cross-lagged panel design to two-wave data from German adolescent students [1088 8th grade students at T1 (Mage = 13.7, SD = 0.53; 53.9% girls) and 845 9th grade students at T2 (Mage = 14.86; SD = 0.57; 55% girls) from the initial sample]. Besides direct effects, three cross-lagged over-time paths were found to be significant: students' perception of peers as positive motivators (PPMs) at the beginning of 8th grade (T1) positively predicts their behavioral school engagement at the end of 9th grade (T2), as well as emotional school engagement at the beginning of 8th grade positively predicts students' perception of PPMs 1.5 years later. Furthermore, behavioral school engagement at T1 functions as a predictor of a student's school self-concept at T2.

The impact of second-generation antipsychotic adherence on positive and negative symptoms in recent-onset schizophrenia.

OBJECTIVE: The aim of the study was to explore the extent to which initial severity of positive or negative symptoms in patients with recent-onset schizophrenia is related to medication nonadherence during the first outpatient year. METHODS: The study involved 64 first-episode schizophrenia patients treated with the second-generation oral antipsychotic medication, risperidone, for 12 months. Symptoms were evaluated using the SANS and SAPS completed every 3 months. Pearson correlations between medication adherence and symptoms were examined over each 3-month interval during 12 months of follow-through treatment. Possible causality was inferred from cross-lagged panel analyses. RESULTS: As expected, higher levels of adherence with antipsychotic medication were generally associated with lower levels of concurrent reality distortion (mean of SAPS delusions and hallucinations). Greater adherence during the 3-month baseline interval was generally associated with lower levels of avolition-apathy as well as alogia throughout the first outpatient year. However, medication adherence was not significantly associated with decreases in avolition-apathy or alogia over time. Cross-lagged panel analyses based on correlation coefficients are consistent with a causal relationship between initial medication adherence and lower levels of alogia. A test of mediation confirmed that an indirect path through reality distortion mediated the relationship between medication nonadherence and alogia. CONCLUSIONS: The associations between greater medication adherence and lower levels of negative symptoms appeared to be accounted for by the relationship of both variables to positive psychotic symptoms. The findings suggest that the impact of second-generation antipsychotic medication on suppression of negative symptoms might be mediated via a reduction in positive symptoms.
