This study aims to validate a Spanish version of the Glasgow Depression Scale for Learning Disability (GDS-LD) and of the Glasgow Depression Care Supplement Scale (GDS-CS).

The GDS-LD was administered to 120 adults with mild and moderate intellectual disabilities and the GDS-CS to the staff from their occupational workshops (n = 120) to detect symptoms of depression. Internal consistency, inter-rater reliability, test-retest reliability, criterion validity, construct validity and the feasibility and applicability of both scales were analysed.

Both scales showed an adequate internal consistency (GDS-LD, a = 0.86) (GDS-CS, a = 0.88). Exploratory factor analysis revealed four well-defined factors in GDS-LD and three in GDS-CS. Pearson correlation analysis data has also been carried out with both tools for test-retest and inter-rater, showing good correlations.

In terms, of limitations, the participants were recruited from the same centre, so this could be a problem in terms of generalisation. In addition, the GDS-LD and GDS-CS scales were developed for people with mild and moderate ID; it would be worth it to develop a version for people with severe and profound disabilities.

From its clinical perspective, it will be possible to have a specific tool that assesses the symptoms of depression in the Spanish population with ID. Furthermore, as it is a user-friendly scale; it can be administrated by both mental health and other professionals working in the field of disability.

The Spanish version of the GDS-LD and GDS-CS showed adequate rates of feasibility and reliability to assess symptoms depression among Spanish speaking adults with mild and moderate ID.

The International Air Transport Association (IATA) New Distribution Capability (NDC) standard aims at modernising the airline distribution landscape. It has supported the spread of Direct Connects by providing a common standard for linking airlines to travel agencies. The purpose of this paper is to analyse the historical development of airline distribution and to derive implications for the future.

This paper follows the approach of Yeoman and McMahon-Beattie (2017) in providing a chronological account based on published research.

Direct Connects are discussed to be a step back in the evolution of the distribution landscape because they foster disaggregation. An analysis of the history of distribution finds that a comparison of Direct Connects to the early stages of computer reservation system technology falls short to recognise the tremendous technological and market changes connected to the internet, cloud computing and the rise of low-cost carriers. Moreover, drawing on the seminal article by Anderson and Tushman (1990) on technical discontinuities and dominant designs, the current state of the distribution landscape is characterised to be an era of ferment that is driven by design competition and that might end up in a new dominant design.

The originality of this paper lies in a critical review of the turning points of distribution. By reviewing the past developments, the paper sheds light on the contribution that IATA NDC and Direct Connect technology might deliver to the field of airline distribution.

Competition had traditionally been highly intense in the airline sector, forcing airlines to continually foster collaborative practices. Although Information & Communication Technologies (ICT) had always been the backbone of any airline collaborative practice, research investigating the role of ICT in supporting collaboration had been solely concentrated on Global Distribution Systems (GDS) and their impact on marketing practices. In this vein, the importance of GDS to support streamlined supply chains in the airline sector has been neglected. This paper aims to show how the functionality and core competences of GDS are exploited to facilitate collaborative supply chain management and enhance airlines’ competitiveness.

The purpose of this paper is to extend the social loafing literature by investigating the role of group development process on perceptions of social loafing within groups. Building on extant literature, it is contended that group members’ association with the group development stages can help in predicting their perceptions of social loafing.

Using a cross-sectional survey data were collected from 164 individuals nested in 39 groups. Mixed-effect modeling in R was unitized to test the proposed hypotheses.

Results of mixed-effect modeling in R show that group development stage of inclusion and dependency (stage 1) has no significant effect on perceptions of social loafing. Whereas, group development stage of counterdependency and fight (stage 2) has positive, and trust and structure (stage 3) and work (stage 4) has negative effect on perception of social loafing by group members.

This study investigates unique relationships between group members’ association with different stages of group development and their perceptions of social loafing. Additionally, a newer, shorter and cost-effective scale to measure four stages of group development is developed.

This study aimed to develop the Thai gaming disorder scale (T-GDS) in children and adolescents to serve medical staff and investigate the effectiveness of the scale.

This is a research and development study. In total, 217 participants were children and adolescents between 8–18 years, then classified into four groups according to Children's Global Assessment Scale (CGAS). The T-GDS was developed; its content validity was then investigated by three experts. Mock assessment was conducted on 15 individuals replicating the actual sample group before the assessment was tested on the sample group by two medical staff. The quality of the scale is assessed through reliability, validity and cut-off point analysis.

Exploratory factor analysis (EFA) extracted four components with 18 items meeting the criteria and have Cronbach's alpha of 0.95. The analysis of ROC curve, to determine the cut-off point, associated the mild game addiction group with T-GDS score = 14; moderate group score = 28; and severe group score = 42.

Investigation of cut-off point by practitioners is vital to compare whether it aligns with the point determined by doctors in game addiction diagnosis. Future research should select critical item in order to reduce the number of questions and construct validity should be examined using confirmatory factor analysis.

This paper provides a comprehensive insight regarding severity of game addiction based on related criteria. As a result, treatment appropriate for each type of severity could be enhanced.

This study aimed to examine for differences on how symptoms relating to depression and anxiety were reported by males and females with intellectual disability as part of the development of the Self‐Assessment Intervention Package (SAINT), a guided self‐help tool.

Three self‐report questionnaires were administered (The Glasgow Depression Scale – Learning Disabilities (GDS‐LD)), Glasgow Anxiety Scale – Intellectual Disabilities (GAS‐ID) and Self‐Assessment Intervention Package (SAINT) to a group of people with mild intellectual disabilities (n=36), to allow comparison of symptom reporting between genders, in particular examining the SAINT across the two groups.

Statistically significant differences in self‐reported symptoms as assessed with SAINT were found between males and females. The symptoms where related mainly to mood and self‐esteem. Overall, endorsement of self‐reported depressive symptoms was between 2.7‐3.2 times higher in female than male patients.

There was evidence to suggest differences in self‐report and symptom profiles of depression and anxiety of males and females with mild intellectual disabilities with females reporting higher in terms of symptoms using the SAINT. The SAINT is a valid tool for screening and self‐reporting symptoms of anxiety and depression in people with intellectual disabilities.

Using data from 36,981 respondents to the Global Drug Survey (GDS) COVID-19 Special Edition, this study aims to compare changes, following the first “lockdown,” in alcohol consumption between lesbian, gay, bisexual and other sexual minority (LGB+) and heterosexual respondents with and without lifetime mental health and neurodevelopmental (MHND) conditions.

Characteristics and drinking behavior of respondents to GDS who disclosed their sexual orientation and past 30-day alcohol use were described and compared. LGB+ participants with and without MHND conditions were compared, and logistic regression models identified correlates of increased drinking among LGB+ people. The impact of changed drinking on the lives of LGB+ participants with and without MHND conditions was assessed.

LGB+ participants who reported that they were “not coping well at all” with the pandemic had twofold greater odds of reporting increased binge drinking. LGB+ participants with MHND conditions were significantly more likely than those without to report increased drinking frequency (18.7% vs 12.4%), quantity (13.8% vs 8.8%) and that changed drinking had impacted their lives.

This study, which has a uniquely large and international sample, explores aspects of alcohol use not considered in other COVID-19 alcohol use research with LGB+ people; and to the best of the authors’ knowledge, this is the first study to explore alcohol use among LGB+ people with MHND conditions.

The purpose of this paper is to examine the evolution and transformation of tourism distribution channels, focusing on the role the internet has played in such a process. It attempts to graphically illustrate, in a temporal manner, the evolving complexity of the tourism distribution systems.

This paper provides insights into the change of the structure of tourism distribution that has not been extensively explored. Indeed, the complexity of the tourism distribution structure has been diagrammatically depicted multiple times by previous researchers and each depiction has contributed to a fuller understanding of the body of knowledge by focusing on different aspects of that structure. This paper builds upon those valuable knowledge contributions by focusing on the evolution of the structure over time, systematically and diagrammatically revealing the progressively larger number of intermediation layers, in spite of concurrent disintermediation and reintermediation activity. This paper does not focus on every action of every participant in detail, but rather focuses on categories of intermediaries, looking at pioneering examples of each. Likewise, the comparative rates of technology adoption in different regions of the world are not investigated.

The complex network proposed in this paper indicates that the advance of information and communication technology has not reduced the number of intermediaries in the distribution channel, but rather resulted in an increasingly complex array of intermediaries. The structure of the tourism industry has taken the form of a complex global network. In the struggle to prosper in this environment, participants at various levels will continue to compete, cooperate, merge, form partnerships, and change relationships on a regular basis.

The extant literature has covered many aspects of intermediation, disintermediation, and reintermediation, albeit with differing terminologies. Most of these studies have adopted a static and cross‐sectional approach in examining the structure and use of tourism distribution channels. This paper examines the historical evolution and progression of tourism distribution channels which is not only important in understanding where we are now as an industry, but also where we came from and where we are heading to.

This paper explores the pattern of technical change in the Korean economy from 1970 to 2013 and investigates its determinants. We use the Classical growth-distribution schedule to show that the labor-saving and capital-using pattern has predominated. For the rationale behind this Marx-biased technical change, we focus on the relationship between technical change and real wage growth via the evolution of labor and capital productivity, and verify the historical direction of technical change against the rise and fall of the working class. Furthermore, we find that the deviation during the post-crisis period from the long-run trend of Marx-biased technical change is not attributable to the vitality of new technological innovations, but rather the reflection of class dynamics over extracting productivity under weaker capital deepening. The results suggest that the recent deterioration of labor share and labor unions in Korea is closely associated with low incentive for technological progress, which contributes to prolonged stagnation.
