- Improving adherence to an online intervention for low mood with a virtual coach: Study protocol of a pilot randomized controlled trialPublication . Provoost, Simon; Kleiboer, Annet; Ornelas, José; Bosse, Tibor; Ruwaard, Jeroen; Rocha, Artur; Cuijpers, Pim; Riper, HeleenInternet-based cognitive-behavioral therapy (iCBT) is more effective when it is guided by human support than when it is unguided. This may be attributable to higher adherence rates that result from a positive effect of the accompanying support on motivation and on engagement with the intervention. This protocol presents the design of a pilot randomized controlled trial that aims to start bridging the gap between guided and unguided interventions. It will test an intervention that includes automated support delivered by an embodied conversational agent (ECA) in the form of a virtual coach. Methods: The study will employ a pilot two-armed randomized controlled trial design. The primary outcomes of the trial will be (1) the effectiveness of iCBT, as supported by a virtual coach, in terms of improved intervention adherence in comparison with unguided iCBT, and (2) the feasibility of a future, larger-scale trial in terms of recruitment, acceptability, and sample size calculation. Secondary aims will be to assess the virtual coach’s effect on motivation, users’ perceptions of the virtual coach, and general feasibility of the intervention as supported by a virtual coach. We will recruit N = 70 participants from the general population who wish to learn how they can improve their mood by using Moodbuster Lite, a 4-week cognitive-behavioral therapy course. Candidates with symptoms of moderate to severe depression will be excluded from study participation. Included participants will be randomized in a 1:1 ratio to either (1) Moodbuster Lite with automated support delivered by a virtual coach or (2) Moodbuster Lite without automated support. Assessments will be taken at baseline and post-study 4 weeks later. Discussion: The study will assess the preliminary effectiveness of a virtual coach in improving adherence and will determine the feasibility of a larger-scale RCT. It could represent a significant step in bridging the gap between guided and unguided iCBT interventions.
- Validation of a job satisfaction scale for predicting employee churn in commercial airlines in PortugalPublication . Brito, António Pimenta de; Moreira, Ana; Sousa, Maria JoséPurpose – The purpose of this study is to validate a job satisfaction scale that can predict employee churn for Portuguese commercial airline companies. Design/methodology/approach – A total of 369 subjects voluntarily participated in this study, all of whom worked for commercial air transport companies. An exploratory and confirmatory factor analysis was carried out to test the instrument. Findings – The results of the psychometric qualities of this instrument indicate that it can be used in future empirical studies. This instrument assesses various dimensions of job satisfaction: leadership, safety, work/life balance, career and pay. Research limitations/implications – One of the limitations of this study is the small sample size and the data collection process. Another limitation is that the questionnaire is self-administered and consists of closed questions. Practical implications – This turnover, satisfaction and performance assessment can be critical, especially when companies struggle with high employee turnover like aviation companies. Aviation professionals are a very skilled profession, with high qualification costs. Social implications – By providing a reliable tool to measure and improve job satisfaction, the research can help reduce employee turnover, leading to more stable employment in the airline industry in Portugal and other countries. Originality/value – By presenting a validated job satisfaction scale tailored for predicting employeechurn specifically within Portuguese commercial aviation companies. This concern benefits employees’ mental health, job security and enhances service quality for assengers
