El objetivo de este estudio fue analizar el comportamiento de los practicantes de ejercicio físico durante dos años, considerando su frecuencia como un predictor de la frecuencia futura. Participaron en este estudio 4788 nuevos practicantes de ejercicio físico (mujeres = 2556) con edades comprendidas entre 18 y 75 años. El acceso a gimnasios y health clubs se recopiló utilizando los sistemas electrónicos. Los datos se analizaron utilizando un modelo de ecuación estructural y un modelo de mediación. En cuanto a la tasa de abandono y posterior exclusión del análisis: 39% abandonó la práctica de ejercicio físico entre los primeros seis meses (T1) y los siguientes seis meses (T2); 25% abandonó la práctica entre T2 y seis meses después de un año de práctica regular (T3); y 10% abandonó entre T3 y seis meses después de un año y medio de práctica regular (T4). Según los resultados del modelo de ecuaciones estructurales, se encontraron varios efectos directos e indirectos significativos, lo que sugiere que T2 y T3 pueden ser mediadores entre T1 y T4. Según los resultados del modelo de mediación, es posible observar que el efecto directo no es significativo. Los resultados muestran la existencia de una mediación total entre el período T1 → T4, ya que el efecto indirecto total es significativo y superior al efecto directo. Las personas que practican ejercicio físico al menos dos veces por semana sin interrupción fueron las que tenían más probabilidades de permanecer en la práctica después de dos años de monitorear su comportamiento. This study aimed to examine the behavior of exercisers across two years, considering their exercise frequency as a predictor of future frequency. In total, 4788 new gym exercisers (female = 2556) aged between 18 and 75 years were enrolled for analysis. Adherence. Computerized records at the gyms and health clubs were used to measure exercise adherence. The collected data was analyzed using structural equation modelling and mediation model specifications. Regarding the dropout rate and later exclusion from the analysis: 39% dropped out within the first six months (T1) and the following six months (T2); 25% withdraw the practice between T2 and six months after one year of regular practice (T3); and 10% dropped out between T3 and six months after a year and a half of regular practice (T4). According to the results of the structural equation model, several significant direct and indirect effects were found, thus suggesting that T2 and T3 may play a mediation role between T1 and T4. Looking at the results from the mediation model, it is possible to observe that the direct effect was not significant. The results show the existence of total mediation between the period T1 → T4, since the total indirect effect is significant and greater than the direct effect. Individuals who practice physical exercise at least twice a week without interruption were those who were more likely to remain in practice after two years of monitoring their behavior. Lo scopo di questo studio era di analizzare il comportamento dei professionisti dell'esercizio fisico per due anni, considerando la loro frequenza come un fattore predittivo della frequenza futura. In questo studio hanno partecipato 4788 nuove praticanti di esercizio fisico (femmina = 2556) di età compresa tra 18 e 75 anni. L'accesso alle palestre e ai centri benessere è stato raccolto utilizzando i sistemi elettronici delle palestre. I dati sono stati analizzati utilizzando un modello di equazione strutturale e un modello di mediazione. Per quanto riguarda il tasso di abbandono e la successiva esclusione dall'analisi: 39% ha abbandonato la pratica dell'esercizio fisico tra i primi sei mesi (T1) e i successivi sei mesi (T2); 25% ha rinunciato alla pratica tra T2 e sei mesi dopo un anno di pratica regolare (T3); e 10% ha abbandonato tra T3 e sei mesi dopo un anno e mezzo di pratica regolare (T4). Secondo i risultati del modello di equazione strutturale, sono stati trovati diversi effetti diretti e indiretti significativi, suggerendo così che T2 e T3 possono essere mediatori tra T1 e T4. Secondo i risultati del modello di mediazione, è possibile osservare che l'effetto diretto non è significativo. I risultati mostrano l'esistenza della mediazione totale tra il periodo T1 → T4, poiché l'effetto indiretto totale è significativo e superiore all'effetto diretto. Le persone che praticano esercizio fisico almeno due volte alla settimana senza interruzione erano quelle che avevano maggiori probabilità di rimanere in pratica dopo due anni di monitoraggio del loro comportamento. O objetivo deste estudo consistiu em analisar o comportamento dos praticantes de exercício físico ao longo de dois anos, considerando a sua frequência como preditor da frequência futura. Participaram neste estudo 4788 novos praticantes de exercício físico (feminino = 2556) com idades compreendidas entre os 18 e 75 anos. Foi recolhida os acessos aos ginásios e health clubs com recurso aos sistemas eletrónicos dos ginásios. Os dados foram analisados com o recurso a um modelo de equações estruturais e um modelo de mediação. Relativamente à taxa de abandono e posteriormente exclusão da análise: 39% abandonaram a prática de exercício físico entre os primeiros seis meses (T1) e os seis meses seguintes (T2); 25% desistiu da prática entre T2 e os seis meses após um ano de prática regular (T3); e 10% abandonaram entre T3 e os seis meses após um ano e meio de prática regular (T4). De acordo com os resultados do modelo de equações estruturais, foram encontrados diversos efeitos diretos e indiretos significativos, sugerindo assim que T2 e T3 poderão ser mediadores entre o T1 e T4. De acordo com os resultados do modelo de mediação é possível observar que o efeito direto não é significativo. Os resultados mostram a existência de mediação total entre o período T1 → T4, dado o efeito indireto total ser significativo e superior ao efeito direto. Os indivíduos que praticam exercício físico pelo menos duas vezes por semana sem interrupção foram aqueles que demonstraram maior probabilidades em se manterem na prática após os dois anos de acompanhamento do comportamento.

In this study, we investigated the relations between family interaction, gratitude, and depressive symptoms among Chinese emerging adults. It also investigated gratitude as a mediator in the relation between family interaction and depression. Data were obtained from 321 college students who completed the online questionnaire about the Family Assessment Instrument, Gratitude Questionnaire, Patient Health Questionnaire, and demographic information. Structural equation modeling (SEM) was used to test hypotheses and bootstrapping with 5,000 resamplings (95% confidence interval) was used to confirm the mediation model. Results showed that gratitude partially mediated the relation between family interaction and depression. In other words, students with healthy family interaction, as indicated by perceived better family communication, mutuality, and harmony with family members, tended to report higher general gratitude, and subsequently diminished depressive symptoms. The practical implications were discussed.

The aim of this study was to investigate the degree to which genetic and environmental influences affect variation in adolescent exercise behavior. Data on regular leisure time exercise activities were analyzed in 8,355 adolescent twins, from three-age cohorts (13-14, 15-16, and 17–19 years). Exercise behavior was assessed with survey items about type of regular leisure time exercise, frequency, and duration of the activities. Participants were classified as sedentary, regular exercisers, or vigorous exercisers. The prevalence of moderate exercise behavior declined from age 13 to 19 years with a parallel increase in prevalence of sedentary behavior, whereas the prevalence of vigorous exercise behavior remained constant across age cohorts. Variation in exercise behavior was analyzed with genetic structural equation modeling employing a liability threshold model. Variation was largely accounted for by genetic factors (72% to 85% of the variance was explained by genetic factors), whereas shared environmental factors only accounted for a substantial part of the variation in girls aged 13-14 years (46%). We hypothesize that genetic effects on exercise ability may explain the high heritability of exercise behavior in this phase of life.

Drawing on conservation of resources (COR) theory, this study examines how and when sincere social interaction affects tourist immersion at the destination. We develop a moderated mediation model in which emotional solidarity mediates the relationship between sincere social interaction and tourist immersion, while extraversion moderates the link between sincere social interaction and emotional solidarity. Data were collected from 391 tourists via an online survey and were analyzed using partial least squares structural equation modeling (PLS-SEM). The findings indicate that sincere social interaction directly influences tourist immersion, and this relationship is mediated by emotional solidarity. Furthermore, extraversion significantly moderates the effects of sincere social interaction on emotional solidarity, and this effect is stronger for tourists with high extraversion scores. Additionally, extraversion strengthens the indirect link between sincere social interaction and tourist immersion, and again, the link is stronger for highly extraverted tourists.

Purpose Taking a social identity approach, the purpose of this paper is to examine the extent to which age-based stereotype threat mediates the relationships between older workers’ negative age-based metastereotypes and two negative work attitudes: organizational disidentification and work disengagement. Design/methodology/approach A two-wave cross-sectional design was adopted to collect data from 423 blue-collar older workers of the Portuguese manufacturing sector. Structural equation modeling was used to test the mediation model. Findings The analyses show that age-based stereotype threat partially mediates the relationship between negative age-based metastereotypes and negative work attitudes. Moreover, findings suggest that older workers respond to negative age-based metastereotypes through threat reactions, and undesirable work attitudes. Originality/value This paper contributes to the literature by showing the importance of negative age-based metastereotypes and age-based stereotype threat in workplace dynamics. It also provides evidence that age threats impair the relationship older workers keep with their organization and their work.

Many studies demonstrate the importance of communication in project performance. However, little is known about how project communication exerts its effects on the outcomes of capital projects that have a large impact on environmental and economic sustainability. Using a longitudinal survey and bootstrap-based structural-equation modeling, this study uncovers how project competencies and team innovative behavior affect the relationship between project communication and capital project performance. This study collects repeated measures from project managers at two time points: immediately after the initiation and planning stages end and immediately after project completion. Excluding responses with missing data, this study’s sample includes 108 capital projects. This study finds that project technical and managerial competencies completely mediate the relationship between project communication and project performance. This study also finds that team innovative behavior affects project performance through the mediating effect of project technical competence. Team innovative behavior also moderates the relationship between project technical competence and project performance. Project communication has the largest effect on project performance despite having the smallest direct effect; project managerial competence possesses the next-largest effect on project performance despite having the largest direct effect. This study discusses the managerial and research implications.

Purpose Organizational democracy is the new model of organizational design for a Democratic Age, and out of this new model grows a freedom-centered and healthy climate. Democratic management is a key to greater organization success and a necessity to gain higher levels of performance and innovation. The purpose of this paper is to explore the antecedents and consequences of organizational democracy in an Iranian context. Design/methodology/approach Statistical population includes the employees of the Gas Company of Isfahan Province. For data analysis, 263 accurate completed questionnaires are used. Structural equation modeling is applied to investigate the relationship between the research variables. Findings The findings showed that some types of organizational culture (i.e. self-criticism, team, and participatory culture) (β=0.33); and some dimensions of organizational structure (i.e. decentralization, flat hierarchy, and less formalization) (β=0.55) as antecedent variables have a significant direct effect on organizational democracy. Also, organizational democracy has a significant direct effect on human resources outcomes consist of organizational commitment, self-efficacy, and improving work relationships (β=0.64); and organizational outcomes consist of organizational learning and organizational agility (β=0.96). Originality/value Despite years of encouragement from consultants and theorists, managers have generally shown little interest toward democratic process as a system of decision making and management in organizations. This study proposes a comprehensive model for identifying the antecedents and consequences of organizational democracy. Most studies in this field are theoretical rather than empirical. But, in this research, the proposed relationships are examined empirically.
