This study empirically investigated the effectiveness of the characteristics of sports sharing economy services that has been highlighted recently. The study used consumers’ attitude and trust as parameters of the association between the characteristics and use intention of consumers. There are three research questions in the study. The first question is whether the characteristics of sports sharing economy services affect the consumers’ use intention. The second question is whether the characteristics of sports sharing economy services affect the attitude of consumers and the trust level in sports sharing economy services. The third question is whether the attitude and trust level of consumers mediate sports sharing economy services and use intention. A survey was conducted among college students using a convenient sampling method. We found that: (1) service characteristics such as usefulness, bonding, and consistency had a positive influence on use intention, and risk factor had a negative influence; (2) the service characteristics significantly influenced consumer attitudes and trust of the sharing economy services; usefulness, bonding, and consistency had a positive influence, and risk factor had a negative influence; and (3) the attitude and trust of consumers toward sharing economy services affected use intention; usefulness, bonding, and sustainability had a positive influence, while risk factor had a negative influence. Thus, it was confirmed that the attitude and trust level of consumers mediated sports sharing economy services and use intention. This study also suggested academic and practical implications to establish a more effective sports sharing economy service marketing strategy and develop quality content in relation to the service characteristics and consumers.

“…48,49 The analysis procedure was performed in the following 3 stages: (1) investigating the possibility of factor analysis, (2) determining the number of factors by an exploratory rotation, using geomin oblique rotation because the correlation between each factor was not 0, and (3) conducting factor analysis based on oblique rotation to a partially specified target. [48][49][50] We consulted the following fit indices to determine global model fit: (1) comparative fit index (CFI), 51 (2) Tucker-Lewis incremental fit index (TLI), 52 (3) root mean square error of approximation (RMSEA), 53 and (4) standardized root-mean-square residual (SRMR). 54 To determine good fit of the model, the following values were used: CFI and TLI above .90, and RMSEA below .08, and SRMR below .10.…”

“…In addition, the correlations between factors in a partially specified target rotation increased compared to the factors in an exploratory rotation (.406). In this study, given that the modification index value was less than 10 for covariance between measurement errors, no further analysis, such as exploratory structural equation modeling, was performed 50…”

Study Objectives: This study aimed to examine psychometric properties of the Disturbing Dream and Nightmare Severity Index (DDNSI) in individuals aged between 18 and 39. Methods: All participants (n = 674) were asked to complete the DDNSI, including the modified Nightmare Effects Survey. Additionally, 109 participants were tested for test-retest reliability after 3 months. Among our sample, 229 (33.9%) reported having at least 1 nightmare per month. Results: Internal consistency was evaluated for the total sample (Cronbach's α = .920) and separately for individuals reporting more than once per month (Cronbach's α = .755). Test-retest reliability after 3 months was .705. Convergent validity of the DDNSI with Nightmare Effects Survey was also satisfactory (r = .638, P < .001). Finally, exploratory factor analysis was conducted to explore the construct of the DDNSI, and results indicated that it consisted of 2 factors, nightmare frequency and nightmare distress [ χ 2 (df ) = 2.241(1) Δχ 2 (Δdf ) = 155.575(4), Tucker-Lewis incremental fit index = .980, root mean square error of approximation (90% confidence interval) = .074 (0, .208), standardized root-mean-square residual = .011]. Conclusions: The DDNSI is a reliable measure of nightmare severity that can be used in various settings.

“…The present study followed the exploratory factor analysis procedures of Lee et al 26 and also referenced Fabrigar and Wegener. 27 The tools used for analysis were SPSS (version 23.0, IBM Corp., Armonk, NY, USA), Factor 10.8, Mplusn 8.1.…”

tervention, later developmental presentation is known to be different. 3 It has been reported that the earlier the intervention through early screening, the better the prognosis for the child's language, emotional, behavioral, and academic development. Infants receiving ASD diagnosis and intervention after three years of age have been found not to benefit in terms of brain development plasticity. Given the known effectiveness of early screening and intervention for ASD, research on screening instruments for early childhood ASD was launched as a national project in South Korea in 2014. 4 The process of ASD-related early recognition, screening, and intervention has tended to be slow in South Korea. 5,6 According to one South Korean study, among various types of disorders, ASD showed the largest difference between the time of discovery by parents and the time of diagnosis; further,a lack of assessment instruments for developmentally disabled infants was reported to pose significant difficulties at clinical sites. 7 A study of 84 young (one to three years) children with ASD was investigated the major problems reported by the parents. In terms of the initial recognition of the problems, 28.3%
