Planning and performance in teams: A Bayesian meta-analytic structural equation modeling approach.

We meta-analyzed the relationship between team planning and performance moderated by task, team, context, and methodological factors. For testing our hypothesized model, we used a meta-analytic structural equation modeling approach. Based on K = 33 independent samples (N = 1,885 teams), a mixed-effects model indicated a non-zero moderate positive effect size (ρ = .31, 95% CI [.20, .42]). Methodological quality, generally rated as adequate, was unrelated to effect size. Sensitivity analyses suggest that effect sizes were robust to exclusion of any individual study and publication bias. The statistical power of the studies was generally low and significantly moderated the relationship, with a large positive relationship for studies with high-powered (k = 42, ρ = .40, 95% CI [.27, .54]) and a smaller, significant relationship for low-powered studies (k = 54, ρ = .16, 95% CI [.01, .30]). The effect size was robust and generally not qualified by a large number of moderators, but was more pronounced for less interdependent tasks, less specialized team members, and assessment of quality rather than quantity of planning. Latent class analysis revealed no qualitatively different subgroups within populations. We recommend large-scale collaboration to overcome several methodological weaknesses of the current literature, which is severely underpowered, potentially biased by self-reporting data, and lacks long-term follow-ups.

Longitudinal Effects of a sit-stand desk intervention - persistence, Fade-Out, and psychological momentum: a Randomized Controlled Trial.

BACKGROUND: This study examined whether the effects of a sit-stand desk (SSD) intervention on employees' musculoskeletal complaints (i.e., intensity and prevalence) and activation (i.e., vigilance and vitality) persist or fade out and whether velocity and acceleration of health improvements can predict medium-term (six-month) and long-term (24-month) improvements. Drawing from dynamic models of self-regulation, as well as the psychological momentum theory, we hypothesized that velocity and acceleration of health improvements in the early stages of the intervention would predict medium-term health improvements, which sustain long-term. METHODS: We used data from a six-month seven-wave randomized controlled trial with employees in mostly sedentary occupations and supplemented this by follow-up data from the same participants 18 months later, resulting in eight waves. RESULTS: Bayesian structural equational modeling revealed no significant intervention effect after 24 months implying a fade-out. But more importantly, velocity and, partially, acceleration of health improvements at earlier stages predicted medium-term improvements in musculoskeletal complaints and long-term improvements in vigilance. CONCLUSION: The findings of this study suggest that positive intervention effects fade out over time and health effects benefit from prompt progresses at the beginning of the intervention, warranting exploration in prolonged longitudinal studies.

Losing and regaining organizational attractiveness during the recruitment process: a multiple-degment factorial vignette study / Ganar y recuperar atractivo organizacional durante el proceso de reclutamiento: un estudio factorial multisegmentario con viñetas

How applicants’ perceptions of organizational attractiveness (OA) change over the recruitment process and whether OA, once lost, can ever be regained, has hardly been investigated. Therefore, drawing on organizational justice and signaling theories, we examined the effects of treatment (fair vs. unfair), re-evaluation (positive vs. negative), and outcome (offer vs. rejection) on OA. Results from a multiple-segment factorial vignette study (N = 193 employees) showed a reduction in OA (67%) after applicants were treated unfairly. Up to 24% of this loss was regained in subsequent stages through positive re-evaluation and by being offered a job. The results also showed a reduction in OA (52%) for applicants who were treated fairly but re-evaluated their experience negatively and received a rejection. Thus, one good experience may not be enough to attract applicants, and understanding the combined effect of experiences is even more important than understanding the effect of a single experience.(AU)

Apenas se ha indagado en cómo cambia la percepción del atractivo de la organización (AO) de los aspirantes a lo largo del proceso de reclutamiento y si puede recuperarse cuando se pierde. Así, partiendo de la justicia organizativa y de las teorías de la señalización analizamos el efecto del tratamiento (justo vs. injusto), reevaluación de las teorías de justicia organizacional (positiva vs. negativa) y resultados (oferta vs. rechazo) en el AO. Los resultados de un estudio factorial multisegmentario con viñetas (N = 193 empleados) mostraron una disminución del AO (67%) después de haber tratado a los aspirantes de modo injusto. Hasta un 24% de esta pérdida se recuperó en etapas posteriores gracias a una reevaluación positiva y a una oferta de trabajo. Los resultados igualmente mostraron una disminución del AO (52%) en los aspirantes a los que se trató de modo justo pero reevaluaron su experiencia negativamente y sufrieron rechazo. Así, una buena experiencia no garantiza que se atraiga a los aspirantes. Además, desentrañar el efecto combinado de las experiencias resulta aún más importante que explicar el efecto de una única experiencia.(AU)

Teams in Transition: A Three-Wave Longitudinal Study of Reflection, Implicit and Explicit Coordination and Performance Improvements.

Research has shown that team reflection is a critical transition process for coordination processes and team performance, but our understanding of its dynamics and relationship to action processes and performance is incomplete. The goal of the present study was to examine the long-term change in reflection in teams over time and explore whether these changes are related to implicit and explicit coordination processes and performance improvement. Drawing on the recurring phase model of team processes and team reflexivity theory, we hypothesized that team reflection is at least stable or increases over time for dissimilar tasks, that reflection trajectories are positively associated with implicit and negatively associated with explicit coordination in the later phases, and that implicit coordination mediates the relationship between team reflection and performance improvement. This model was tested in a three-wave longitudinal study (N = 175 teams) over a 2-months period. Results from growth curve modeling and structural equation modeling provided support for our hypotheses.

Beneficial, adverse, and spiraling health-promotion effects: Evidence from a longitudinal randomized controlled trial of working at sit-stand desks.

In a 6-month longitudinal randomized field experiment, we examined how using height-adjustable sit-stand desks could have beneficial, adverse, and spiraling effects on people's musculoskeletal and psychovegetative complaints, and on positive (vitality and vigilance) and negative psychological symptoms, namely, stressor uncontrollability (i.e., perceived uncontrollability of workload), psychological tension, and mental tiredness. A total of 127 employees in various, mostly sedentary, occupations were randomly assigned to either the intervention or the control group. Variables were assessed monthly for 6 months on a self-reported basis. Bayesian structural equation modeling showed that the intervention produced large inhibiting between-subjects effects for musculoskeletal problems in the neck, back, and shoulders (ß ranged between -.26 and -.21). Within-subject analyses revealed that the intervention produced large inhibiting effect sizes for intensity (g = 3.06) and prevalence of musculoskeletal (g = 1.19) and psychovegetative complaints (g between 0.76 and 1.57). For negative psychological symptoms (i.e., psychological tension and mental tiredness), participants in the intervention group showed a steeper decrease than participants in the control group (g between 2.34 and 3.74). For positive indicators (i.e., vitality and vigilance), the intervention produced large promoting effects for participants in the intervention group compared with participants in the control group (g between 0.70 and 1.65). There was no change in stressor uncontrollability between the two groups. Finally, findings suggest that sit-stand desks can be effective in improving occupational health by weakening a downward-spiraling effect.

Acquisition of dental skills in preclinical technique courses: influence of spatial and manual abilities.

Sixty years of research have not added up to a concordant evaluation of the influence of spatial and manual abilities on dental skill acquisition. We used Ackerman's theory of ability determinants of skill acquisition to explain the influence of spatial visualization and manual dexterity on the task performance of dental students in two consecutive preclinical technique courses. We measured spatial and manual abilities of applicants to Hamburg Dental School by means of a multiple choice test on Technical Aptitude and a wire-bending test, respectively. Preclinical dental technique tasks were categorized as consistent-simple and inconsistent-complex based on their contents. For analysis, we used robust regression to circumvent typical limitations in dental studies like small sample size and non-normal residual distributions. We found that manual, but not spatial ability exhibited a moderate influence on the performance in consistent-simple tasks during dental skill acquisition in preclinical dentistry. Both abilities revealed a moderate relation with the performance in inconsistent-complex tasks. These findings support the hypotheses which we had postulated on the basis of Ackerman's work. Therefore, spatial as well as manual ability are required for the acquisition of dental skills in preclinical technique courses. These results support the view that both abilities should be addressed in dental admission procedures in addition to cognitive measures.

Reflexivity in Teams: A Review and New Perspectives.

Team reflexivity posits that the extent to which teams reflect upon and adapt their functioning is positively related to team performance. While remarkable progress has been made to provide evidence of this relationship, the underlying framework is missing elements of current theoretical streams for analyzing and describing teamwork, leaving the diversity of effects of team reflexivity often untouched. In this article, we present an update for this framework, by reviewing previous research on reflexivity, addressing gaps in the literature, and revising the original model by integrating feedback and dynamic team effectiveness frameworks for describing temporal developments of reflexivity. We furthermore propose a new dimensional structure for reflexivity, relying on prior work conceptualizing teams as information-processing systems that learn and advance through social-cognitive elements. Our model is therefore not only suitable for explaining the diverse set of relationships between team reflexivity on outcomes, but also provides valuable directions for viewing reflexivity as process that takes place during both transition and action phases of teamwork. We conclude with implications for managers, identify limitations, and propose an agenda for further research into this area. This article contributes an extended perspective relevant for further theory development and for effectively managing reflexivity in teams.

Formative versus reflective measurement: an illustration using work-family balance.

The aim of this article is to propose the formative measurement approach that can be used in various constructs of applied psychology. To illustrate this approach, the authors will (a) discuss the distinction between commonly used principal-factor (reflective) measures in comparison to the composite (formative) latent variable model, which is often applied in other disciplines such as marketing or engineering, and (b) point out the advantages and limitations of formative specifications using the example of the work-family balance (WFB) construct. Data collected from 2 large cross-sectional field studies confirm the reliability and validity of formative WFB measures as well as its predictive value regarding criteria of WFB (i.e., job satisfaction, family satisfaction, and life satisfaction). Last, the specific informational value of each formative indicator will be demonstrated and discussed in terms of practical implications for the assessment in different psychological fields.
